How to Update Your Sole Proprietorship Registration When Circumstances Change

Starting and running a sole proprietorship can be an incredibly rewarding endeavor. However, as your business grows and changes, so too may your requirements for registration and compliance. The need to update your sole proprietorship registration can arise from various circumstances, such as a change of business name, change of business address, expansion of business activities, or even a shift in ownership. These changes necessitate timely updates to keep your business compliant with local laws and regulations. This article provides detailed information on how to effectively update your sole proprietorship registration, ensuring your business is operating legally and efficiently.

Understanding Sole Proprietorship

Before delving into the specifics of updating your registration, it is essential to understand what constitutes a sole proprietorship. A sole proprietorship is a type of business entity owned and managed by one individual. Characteristics of a sole proprietorship include:

- Simplicity: The formation and operation of a sole proprietorship are simpler compared to other business structures. There are fewer regulatory requirements, making it an attractive option for many entrepreneurs.

- Ownership: The owner has complete control over all business decisions and retains all profits, but is also personally liable for all debts and obligations incurred by the business.

- Tax Treatment: Income generated by the business is reported on the owner's personal tax return, simplifying tax filing.

Understanding these aspects is vital for any sole proprietor contemplating updates or changes to their registration.

When Do You Need to Update Your Registration?

There are several key situations in which you may need to update your sole proprietorship registration:

Change of Business Name

If you decide to rebrand your business or simply want to operate under a different name, you must update your registration to reflect this change. This not only ensures compliance with local regulations but also helps maintain your brand identity.

Change of Business Address

If you move your business from one location to another, updating the registered address is crucial. The business address is often listed publicly, and failing to keep this information current can lead to complications with tax authorities and clients.

Expansion of Business Activities

As your business grows, you may decide to expand the range of services or products you offer. It's important to update your registration to indicate these changes, as different activities might require different licenses or permits.

Change in Ownership Structure

If there are changes in ownership- for instance, if you enter into a partnership or if your business is inherited- it may be necessary to update your registration to reflect the new ownership structure.

Steps to Update Your Sole Proprietorship Registration

Updating your registration involves several critical steps. Below are the steps you should typically follow:

Step 1: Identify Your Local Registry Requirements

Start by identifying where you registered your sole proprietorship. This is usually a government office or agency, such as:

- Department of Revenue

- Secretary of State

- Local business registry office

Each jurisdiction has its own rules and requirements for updating registration.

Step 2: Gather Necessary Documentation

Once you've established where to go, gather the documentation necessary for making updates. Generally, you may require:

- Proof of your new business name (if applicable)

- Proof of your new business address (such as a lease agreement)

- Updated business licenses or permits

- Identification (e.g., driver's license or government-issued ID)

Ensure you have all required documents ready to avoid delays in processing.

Step 3: Complete the Required Forms

Most jurisdictions require specific forms to be filled out when updating registration. These could typically include forms for:

- Name change

- Address change

- Activity update

- Ownership transfer

Download, print, and complete these forms from your local registry's website or obtain them in person.

Step 4: Submit Your Application

Once you have completed the necessary forms and gathered all supporting documentation, submit your application. This can often be done online, via mail, or in person, depending on local requirements.

Step 5: Pay Appropriate Fees

Updating your registration may come with associated fees. Be prepared to pay a fee at the time of application submission, which can vary significantly depending on the nature of the update and your jurisdiction.

Step 6: Await Confirmation

After submitting your application, it may take some time for the changes to be processed. Keep an eye out for any correspondence from the registration office to confirm that your updates have been made.

The Importance of Keeping Your Registration Updated

Keeping your sole proprietorship registration updated is important for several reasons:

Legal Compliance

Failure to update your registration can lead to legal repercussions, including fines or penalties. Various authorities may require current information about your business, and non-compliance can have serious financial implications.

Business Credibility

An up-to-date registration enhances your business's credibility in the eyes of customers, suppliers, and other stakeholders. Clients are more likely to trust a business that maintains transparency about its operations.

Protection of Intellectual Property

When you update your business name or any related branding, ensuring that your registration reflects these changes protects your intellectual property and helps prevent potential legal issues.

Tax Responsibilities

It is crucial to ensure that your business tax records reflect the current information associated with your business. Accurate registration reduces the risk of tax issues and makes it easier to manage your tax obligations.

Common Challenges in Updating Sole Proprietorship Registration

Updating your registration can be straightforward, but several common challenges may arise:

Bureaucratic Delays

Government agencies often deal with a high volume of applications, which can lead to unexpected delays. It's essential to allocate adequate time for your application to be processed.

Lack of Clarity on Requirements

Each jurisdiction has unique regulations and requirements for updating registrations. Lack of clarity can be a significant barrier, so it's vital to research thoroughly or consult local authorities if you're unsure.

Inaccurate Documentation

Submitting incorrect or incomplete documentation can lead to rejections and delays. Double-check all materials before submission to ensure compliance with local requirements.

Best Practices for Managing Your Sole Proprietorship Registration

While keeping your registration updated is crucial, maintaining good practices from the get-go can save you time and hassle in the long run.

Maintain a Clear Record of All Changes

Keep clear documentation of all changes made to your business, including registrations, licenses, and any permits obtained. This makes future updates easier and ensures you have a readily available history of your business's evolution.

Know Deadlines and Renewal Dates

Stay informed about renewal deadlines for permits and licenses associated with your business. This knowledge can help you avoid late fees and ensure continued compliance.

Consult with Professionals

When in doubt, consider consulting professionals such as tax advisors or legal experts familiar with business regulations. Their insights can help you navigate complexities and reduce the potential for mistakes.

Establish a Routine Check

Schedule regular reviews of your business registration and associated documents. An annual audit can help you stay ahead of any necessary updates and ensure you remain compliant.

Pursuing Additional Resources for Guidance

In addition to the steps outlined above, consider pursuing additional resources for further guidance on business registration processes.

Government Websites

Most local government entities maintain websites that offer a wealth of information regarding business registration, required updates, forms, and associated fees. These websites should be your first stop for research.

Local Business Associations

Many cities and municipalities have local business associations or chambers of commerce that provide support to small business owners. These organizations often offer seminars, forums, or webinars that can provide valuable insights into managing your business registration.

Online Courses and Workshops

Consider enrolling in online courses or workshops focusing on business compliance and registration processes. Many institutions provide affordable options for education on this topic.

Alternatives to Sole Proprietorships

While a sole proprietorship is a popular choice for many entrepreneurs, it's essential to consider other business structures if your circumstances change significantly.

Partnerships

If you're looking to bring in a partner or investor, forming a Partnership may be a better option. Partnerships involve multiple individuals sharing ownership and are often regulated differently than sole proprietorships.

Limited Liability Companies (LLC)

An LLC can be an attractive alternative if you're looking to separate personal liability from business liability. This structure also provides flexibility in management and tax treatment.

Corporations

Forming a corporation may be beneficial if your business is expanding rapidly or planning to take on investments. This structure provides greater liability protection but comes with more regulatory requirements.

Key Danish Authorities and Systems Involved in Updating Your Registration (Virk, Erhvervsstyrelsen, SKAT)

When you update your sole proprietorship registration in Denmark, you will mainly interact with three key systems and authorities: Virk, the Danish Business Authority (Erhvervsstyrelsen) and the Danish Tax Agency (SKAT/Skattestyrelsen). Understanding who does what helps you avoid mistakes, missed deadlines and unnecessary letters from the authorities.

Virk – your main entry point for business changes

Virk (virk.dk) is the central online portal where you submit almost all changes related to your sole proprietorship. It is not an authority in itself, but a shared platform used by several public bodies.

Through Virk you typically:

• Register a new sole proprietorship and obtain a CVR number
• Change business details such as name, address, industry code (branchekode/NACE), contact information and start or end dates
• Register for or deregister from VAT (moms), payroll tax (lønsumsafgift) and other schemes
• Notify that you start or stop having employees

All updates are made using MitID, and in most cases changes are processed automatically. Once you submit a change via Virk, the information is forwarded to the relevant authority, primarily Erhvervsstyrelsen and Skattestyrelsen.

Erhvervsstyrelsen – CVR and business registration

Erhvervsstyrelsen is responsible for the Central Business Register (CVR). This is where your sole proprietorship’s core registration data is stored and made publicly available. Whenever your circumstances change, you must ensure that your CVR information is updated.

Typical updates handled by Erhvervsstyrelsen via Virk include:

• Change of business name (including adding or removing a secondary name)
• Change of business address or place of business
• Change of industry code (branchekode), for example when you shift from consulting to e‑commerce
• Change of start or end date of the business or specific activities

These changes affect how your business appears in public databases and how other authorities classify your activity. An incorrect industry code can, for example, lead to wrong guidance on tax, VAT or sector‑specific rules.

SKAT/Skattestyrelsen – tax, VAT and duties

Skattestyrelsen (often still referred to as SKAT) is responsible for your tax, VAT and certain duties. While you submit most changes through Virk, they are crucial for how Skattestyrelsen calculates and expects your payments.

Key areas where Skattestyrelsen is involved when you update your registration include:

• Registration and deregistration for VAT (moms) when your turnover crosses the VAT threshold or your activity changes
• Changes in expected profit that affect your preliminary income assessment (forskudsopgørelse) and B‑tax instalments
• Registration as an employer and ongoing reporting of salary, A‑tax and labour market contributions (AM‑bidrag) via eIndkomst
• Registration for payroll tax (lønsumsafgift) for certain VAT‑exempt activities, such as some financial or health services

If you fail to update your information, Skattestyrelsen may calculate your tax and VAT based on outdated data, which can result in incorrect instalments, interest and possible penalties.

How the systems work together in practice

In practice, you usually only log in to Virk to submit your changes. Virk then distributes the information to Erhvervsstyrelsen and Skattestyrelsen. For example, if you change your business address on Virk, Erhvervsstyrelsen updates your CVR record, and Skattestyrelsen uses the new address for tax and VAT correspondence.

Because the systems are connected, one incorrect or missing update can spread across several registers. Keeping your data correct in Virk ensures that both Erhvervsstyrelsen and Skattestyrelsen have the right information about your sole proprietorship at all times.

Updating Your CVR Registration Details (Business Name, Address, and Industry Code)

In Denmark, your sole proprietorship is identified by a CVR number and registered through the Danish Business Authority (Erhvervsstyrelsen). Keeping your CVR registration up to date on Virk is a legal obligation and directly affects how the authorities, banks and customers see your business. Whenever you change your business name, address or industry code (branchekode/NACE code), you must update your registration as soon as possible.

Where and how to update your CVR information

You update your CVR details online via Virk (virk.dk) in the self-service solutions provided by Erhvervsstyrelsen. You log in with MitID and select your sole proprietorship under your profile. From there, you can file a change notification (ændring af virksomhed). Most changes are registered immediately or within a short processing time and are visible in the public CVR register (cvr.dk).

For most sole proprietors, there is no fee for updating basic registration data such as name, address or industry code. However, if your change triggers additional registrations (for example, VAT registration, payroll registration or special permits), separate rules and possible fees may apply.

Changing your business name

Your registered business name (virksomhedsnavn) is the official name that appears in the CVR register, invoices, contracts and communication with authorities. If you change it, you must update it in the CVR system; it is not enough to just change your logo or website.

When choosing a new name, you should ensure that:

• It is not misleading and clearly indicates that you are a sole proprietorship, not for example an ApS or A/S
• It does not infringe existing registered company names or trademarks in Denmark
• It can be used consistently on invoices, contracts, your website and social media

On Virk, you submit a change of name by editing the company’s basic information. The new name will appear in the CVR register once the change is processed. If you use a secondary business name (binavn), you should also update or deregister it if it no longer reflects your activities.

After the change is approved, remember to update:

• Invoice templates and accounting system settings
• Bank and payment providers (e.g. acquiring agreements, MobilePay Erhverv)
• Contracts, terms and conditions, and your website’s legal information
• Insurance policies and any sector-specific registrations or licences

Updating your business address

Your registered business address is used by Erhvervsstyrelsen, the Danish Tax Agency (Skattestyrelsen/SKAT), your municipality and other authorities. It also appears publicly in the CVR register. You must update your address when you:

• Move your business to a new location in Denmark
• Start working from a different home address than before
• Relocate your main place of business abroad

The address you register must be an address where you can actually be reached and where you can receive physical mail, if relevant. If you run your business from home, you normally register your private address as the business address, unless you have a separate business location.

When you change your address in the CVR register via Virk, the new address is shared with other public systems. However, you should still check and, if necessary, update:

• NemKonto and your bank, so payments from authorities are not delayed
• Digital mail settings (e-Boks/Mit.dk) and contact details on skat.dk
• Website, social media profiles and online directories
• Insurance coverage, especially if you move to premises with different risk conditions

If your move involves a change of municipality, your local tax, business regulations and certain fees (for example waste collection or local environmental permits) may change. It is therefore important to coordinate the address change with both Erhvervsstyrelsen and your municipality.

Choosing and changing your industry code (branchekode/NACE)

Every Danish business is registered with at least one primary industry code (branchekode, based on the NACE classification). This code describes your main business activity and is used by authorities for statistics, risk assessments, control selection and, in some cases, to determine which rules apply to you.

You should review and, if necessary, change your industry code when:

• Your main activity changes (for example from consulting to online retail)
• A side activity becomes your primary source of turnover
• You add a new line of business that is significantly different from your current code

On Virk, you can update your primary industry code and add secondary codes if you have substantial additional activities. When choosing the correct code, consider:

• Which activity generates the largest share of your turnover
• Where you expect the core of your business to be in the coming years
• Whether the code matches how you present your business to customers and partners

An incorrect or outdated industry code can lead to:

• Increased risk of tax audits if your figures deviate from typical businesses in your registered industry
• Missing out on relevant sector-specific guidance or support schemes
• Misunderstandings with banks, insurers or potential partners who rely on CVR data

How changes interact with VAT (moms) and tax registration

Updating your CVR details does not automatically change your VAT or tax obligations, but certain changes can trigger new requirements. For example:

• If your new activity involves selling goods or services in Denmark and your annual turnover exceeds 50,000 DKK within a 12‑month period, you must be VAT registered
• If you move from purely Danish customers to cross‑border trade within the EU, you may need EU VAT registration and to report via the One Stop Shop (OSS) for certain B2C services and distance sales
• If your new activity involves employees, you must register as an employer and report salary via eIndkomst

When you change business name, address or industry code, always check that your VAT registration, tax prepayments (B‑skat) and preliminary income assessment (forskudsopgørelse) on skat.dk still match your actual situation. If your expected profit changes significantly, you should adjust your preliminary tax to avoid large back payments or unnecessary overpayments.

Practical tips for keeping your CVR data accurate

To avoid problems with authorities and business partners, it is good practice to:

• Review your CVR information at least once a year, for example when preparing your annual accounts
• Update your registration immediately when you decide on a new name, move address or change your main activity
• Keep documentation of your changes (for example board or owner decisions, lease agreements, contracts) together with your accounting records
• Align all systems – accounting software, invoicing tools, website, bank and insurance – with the updated CVR data

Accurate CVR registration strengthens your professional image, reduces the risk of misunderstandings with SKAT and other authorities, and makes it easier to apply for financing, grants or public tenders. If you are unsure which industry code to choose or how a change affects your VAT and tax position, it is often worthwhile to consult a Danish accountant who knows the current rules and thresholds.

How Changes Affect Your Tax and VAT (Moms) Obligations as a Sole Proprietor in Denmark

Any change in your sole proprietorship registration in Denmark can affect how you are taxed and how you handle VAT (moms). Updating your data correctly ensures that SKAT (the Danish Tax Agency) calculates your income tax, labour market contributions and VAT obligations on the right basis, and that you avoid interest, surcharges or fines.

Income tax and AM-bidrag when your business changes

As a sole proprietor, your business income is taxed as personal income. You pay:

• 8% labour market contribution (AM-bidrag) on your business profit before other income taxes
• Personal income tax according to the municipal, church (if applicable) and state tax rates
• Top-bracket tax (topskat) on the part of your personal income that exceeds the current top-tax threshold

When your business circumstances change, your expected profit often changes as well. This should be reflected in your preliminary income assessment (forskudsopgørelse). Typical changes that require an update include:

• Switching from part-time side business to main occupation
• Significant increase or decrease in turnover or profit
• Adding or removing major cost items (for example, rent for business premises, car expenses, employees)

You update your expected business income in TastSelv on skat.dk. SKAT then recalculates your monthly or quarterly tax payments (B-skatterate). If you do not adjust your preliminary income, you risk either a large tax bill with interest and possible surcharge, or overpaying tax throughout the year.

When you must register for VAT (moms)

You must register for VAT when your VAT-liable turnover in Denmark exceeds, or is expected to exceed, 50,000 DKK within a 12‑month period. This threshold applies to most ordinary commercial activities. Some activities are VAT-exempt (for example many health services, certain financial services and some educational services), but even then, changes in your activities can affect your VAT status.

If you expect to pass the 50,000 DKK threshold, you must register for VAT on Virk before you start charging VAT. You cannot legally add VAT to your invoices until you are registered. If you fail to register on time, SKAT can demand payment of VAT retroactively, even if you did not charge it to your customers.

Changing your VAT status when your turnover or activities change

Several types of changes in your sole proprietorship require you to update your VAT registration:

• Turnover rises above or falls below 50,000 DKK: If you exceed the threshold, you must register for VAT. If your VAT-liable turnover falls permanently and clearly below the threshold, you can apply to deregister for VAT, but only if your activity is genuinely minor and not expected to increase again.
• Change in business activities (industry code): If you add new services or products, or change your main activity, your VAT treatment may change. Some activities are fully VAT-liable, some are VAT-exempt, and some have mixed treatment. You must update your industry code (branchekode) and activity description on Virk so that SKAT can assess your VAT obligations correctly.
• Switching between VAT-exempt and VAT-liable activities: If you start offering VAT-liable services in addition to VAT-exempt ones (for example, a therapist who also sells courses or books), you may need to allocate input VAT between VAT-liable and VAT-exempt activities. This affects how much VAT you can deduct on your purchases.

VAT rates and what you must charge

In Denmark, the standard VAT rate is 25% on most goods and services. There is no reduced VAT rate for food, books or similar categories, and there is no general zero-rate for domestic supplies. When you are VAT-registered, you must:

• Charge 25% VAT on your VAT-liable sales, unless a specific exemption applies
• Issue invoices that clearly show the VAT amount and your CVR number
• Report and pay VAT to SKAT according to your assigned reporting frequency

If your business changes so that you start selling products or services to customers in other EU countries or outside the EU, special VAT rules may apply (for example, reverse charge for B2B services in the EU or distance selling rules for digital services). In such cases, you may need to update your registration for EU VAT schemes and adjust how you invoice foreign customers.

VAT reporting frequency and how changes in turnover affect it

Your VAT reporting frequency is determined by your annual turnover:

• Small businesses typically report VAT once a year
• Medium-sized businesses report quarterly
• Larger businesses report monthly

If your turnover increases significantly, SKAT can change your reporting frequency, usually from annual to quarterly or from quarterly to monthly. When this happens, you will receive a notice in your digital mail (e‑Boks). You must then adapt your bookkeeping routines and cash flow planning to the new deadlines.

Conversely, if your turnover falls and remains lower, you may be moved to a less frequent reporting schedule, but this is not automatic in every case. Always check your VAT calendar in TastSelv Erhverv to see your current deadlines.

Deducting business expenses and input VAT after changes

When your business changes, the type and amount of expenses you can deduct for tax and VAT purposes often change as well:

• If you move from home office to rented premises, you may deduct rent and operating costs as business expenses and deduct the related input VAT.
• If you start using a car for business, you must choose between actual costs and standard mileage deduction for tax purposes, and you must follow the specific VAT rules for cars and fuel.
• If you hire employees, salary is not subject to VAT and does not give right to input VAT deduction, but related costs (for example, office equipment) may be VAT-deductible.

Whenever you change your setup, review which expenses are now business-related and how much VAT you can deduct. Proper documentation and updated bookkeeping procedures are essential if SKAT asks for evidence.

Crossing important tax thresholds

Changes in your business income can push you above or below key tax thresholds. This can affect:

• Whether you pay top-bracket tax (topskat) on your personal income
• How much you can contribute to pension schemes with tax advantages
• Whether certain deductions or allowances are reduced or phased out

When you update your registration and preliminary income, you should also consider whether it is time to adjust pension contributions, savings or other tax planning measures. A large, sudden increase in profit without an update to your forskudsopgørelse often leads to an unexpected tax bill later.

Moving, hiring and structural changes – tax and VAT impact

Several common registration changes have direct tax and VAT consequences:

• Changing address or municipality: Your municipal tax rate may change, which affects your total income tax. You must update your address with the National Register (Folkeregisteret) and ensure that your business address and CVR data on Virk match.
• Hiring employees: You must register as an employer, report salaries via eIndkomst, withhold A‑tax and AM-bidrag from employees, and pay ATP and other mandatory contributions. This does not change your VAT status directly, but it changes your cost structure and tax-deductible expenses.
• Changing from side business to main occupation: Your business income may become your primary source of income. You should update your forskudsopgørelse so that B‑tax instalments match your new reality and review whether you need to adjust pension contributions or insurance.

Stopping, pausing or converting your business

If you close, pause or convert your sole proprietorship, you must update your registration and settle your tax and VAT correctly:

• Closing the business: You must deregister for VAT and as an employer (if relevant) on Virk, submit a final VAT return and include your final business result in your personal tax return. You may need to account for VAT on remaining stock or fixed assets.
• Temporarily pausing activity: If you have no VAT-liable turnover for a period, you may still have to submit VAT returns (with zero turnover) unless you are formally deregistered. Check your registration status and deadlines carefully.
• Converting to an ApS or other company form: When you transfer your activity to a company, your tax and VAT treatment changes fundamentally. The company becomes a separate taxpayer and VAT entity. The transfer can often be done tax neutrally if specific conditions are met, but the process is technical and usually requires professional advice.

Why timely updates matter for tax and VAT

Keeping your registration, CVR data and preliminary income updated is not just a formality. It directly affects:

• How much tax and VAT you must pay and when you must pay it
• Your risk of interest, surcharges and fines from SKAT
• Your cash flow and ability to plan investments or withdrawals from the business
• Your chances of passing a tax or VAT audit without problems

Whenever you make a significant change in your sole proprietorship – new activities, higher or lower turnover, new address, employees, or a change in your main occupation – review both your tax and VAT situation and update your registrations accordingly. If you are unsure how a specific change affects your obligations, it is usually more cost‑effective to seek professional advice early than to correct mistakes later.

Updating Registration When You Move Between Municipalities or Abroad

Moving to a new municipality in Denmark or relocating abroad has direct consequences for your sole proprietorship registration. Your address, tax municipality, and in some cases your VAT (moms) and social security position will change. Failing to update your details in time can lead to incorrect tax assessments, delayed mail from the authorities, and potential fines.

Moving to a new municipality within Denmark

When you move your residence and/or place of business to another municipality, you must update your information both as a private person and as a business owner.

As a rule, you must report your move to the National Register (Folkeregisteret) via borger.dk no later than 5 days after you have moved. This update is the basis for which municipality you pay municipal tax to and which municipality administers certain benefits and services.

For your sole proprietorship, you must also update your business registration in the Virk / Erhvervsstyrelsen systems:

• Log in to Virk with MitID
• Find your business under “Mine virksomheder”
• Update the business address and, if relevant, the place of activity (driftssted)
• Check that your contact details, email and phone number are correct

The new address is automatically shared with SKAT (the Danish Tax Agency) through the CVR register. However, you should still verify in skat.dk that your tax information reflects the new municipality and that your preliminary income assessment (forskudsopgørelse) is updated. Municipal tax rates vary between municipalities, so your total tax percentage may change when you move.

If you are VAT registered, your VAT obligations do not disappear when you move municipality. You must continue to submit VAT returns on time (typically quarterly or half-yearly for small businesses) and ensure that your invoices show the correct business address and CVR number.

Moving abroad while keeping your Danish sole proprietorship

If you move abroad but continue to run a Danish sole proprietorship, the situation becomes more complex. You must consider both Danish tax rules and the rules in your new country of residence, as well as any applicable double taxation treaty.

First, you must report your move abroad to the National Register via borger.dk. When you deregister from Denmark, you are usually no longer fully tax resident in Denmark, but you may still be subject to limited tax liability on income connected to your Danish business.

From a business perspective, you must decide whether the sole proprietorship remains registered in Denmark:

• If the business continues to have its main activity and customers in Denmark, you will typically keep your Danish CVR number and VAT registration.
• If the activity is effectively moved abroad and no longer has a real connection to Denmark, it may be more appropriate to close the Danish sole proprietorship and register a business in your new country.

When you keep the Danish sole proprietorship, you must:

• Update the business address in the CVR register to your new foreign address (if the business is effectively managed from abroad)
• Clarify with SKAT whether you are still subject to Danish tax on business profits and how the double taxation treaty applies
• Continue to submit Danish tax returns and VAT returns as long as you are liable to Danish tax and VAT

In some cases, SKAT may consider that the business has a permanent establishment (fast driftssted) in Denmark, for example if you keep premises, employees or a fixed place of business in Denmark. In that case, the profits attributable to the Danish permanent establishment are taxable in Denmark, even if you live abroad.

VAT (moms) and cross-border moves

If you move to another EU country, you must pay particular attention to VAT rules. You may need to:

• Keep Danish VAT registration if you still sell goods or services from Denmark to Danish customers
• Register for VAT in the new EU country if you have a fixed establishment there or exceed local distance selling thresholds
• Apply the correct VAT rules for cross-border B2B and B2C sales within the EU, including reverse charge where applicable

If you move outside the EU, your sales to customers in Denmark and the EU may be treated as imports or exports, with different VAT consequences. In all cases, you must ensure that your invoices, bookkeeping and VAT reporting reflect your actual place of establishment and the correct VAT treatment.

NemKonto, Digital Post and communication with authorities after moving

Whether you move within Denmark or abroad, you must ensure that your NemKonto and Digital Post (e-Boks) are correctly set up. Public authorities, including SKAT and Erhvervsstyrelsen, send important messages and decisions exclusively via Digital Post.

When you move:

• Check that your NemKonto is still linked to an active bank account that you can access from your new location
• Update your contact email and phone number in e-Boks and on skat.dk
• Make sure you can still use MitID from abroad, or arrange alternative access before you move

If you lose access to Digital Post or NemKonto after moving abroad, you risk missing deadlines for tax returns, VAT submissions and other mandatory filings, which can lead to penalties and interest.

When should you consider closing or pausing the business?

If your move means that you will not be actively running the business for a period, you should consider whether to:

• Temporarily pause the business (for example by deregistering for VAT if your turnover drops below the VAT registration threshold of 50,000 DKK over 12 months)
• Fully close the sole proprietorship in the CVR register if you no longer intend to carry out business activity in Denmark

Closing or pausing the business can simplify your tax situation when moving abroad and reduce the risk of errors in your Danish reporting. However, you must still submit final tax returns and VAT returns up to the closing date and keep your accounting records for the required retention period.

Because cross-border moves often involve complex tax and social security issues, it is usually advisable to consult a Danish accountant with experience in international matters before you move, especially if you plan to keep your Danish sole proprietorship active.

Changing from Part-Time Side Business to Main Occupation: Registration Implications

Turning your Danish sole proprietorship from a small side activity into your main occupation is more than just a business decision. It has direct consequences for your registration, tax position, social security, and practical obligations. If you fail to update your information correctly, you risk incorrect tax assessments, loss of deductions, or problems with benefits and pension contributions.

Below you will find the key implications and steps you should consider when your part-time business becomes your primary source of income.

1. Clarifying when your business becomes your main occupation

There is no single legal definition that says your business is “main occupation” from a specific number of hours. In practice, the Danish Tax Agency (Skattestyrelsen) and other authorities look at several factors together:

• Whether the majority of your total working time is spent on the business rather than employment
• Whether the main part of your income comes from the business
• Whether the activity is run with a clear profit motive and on a commercial basis
• Whether you have reduced or ended your employment to focus on the business

Once your business clearly becomes your primary source of income, you should update your registration and tax information so that advance tax (B-skat), VAT (moms) and social contributions reflect the new situation.

2. Updating your registration on Virk and with Erhvervsstyrelsen

When your sole proprietorship changes character from a small side business to your main occupation, you should log in to Virk and review your registration details:

• Business description and industry code (branchekode/NACE) – if your activities have expanded or changed, update your industry code so it reflects your actual main activity. This affects statistics, some regulatory requirements and, in some cases, access to specific schemes or subsidies.
• Contact details and business address – if you now use a separate office, co-working space or shop as your primary place of business, update the address. This can affect municipal rules, local taxes and inspection obligations.
• Start date of significant change – if the shift to main occupation is tied to a specific date (for example, the day you quit your job), note this for your own records and, where relevant, in communication with authorities.

The CVR number itself does not change just because the business becomes your main occupation, but the underlying information must be kept accurate and up to date.

3. Adjusting your preliminary income assessment (forskudsopgørelse)

When your business becomes your main occupation, your business income will typically rise and salary income may fall or disappear. You must update your preliminary income assessment with Skattestyrelsen so that your advance tax payments match your expected income.

In your preliminary assessment you should:

• Increase your expected business profit (overskud af selvstændig virksomhed)
• Reduce or remove expected salary income if you have left your job
• Adjust expected interest, deductions and any transport deductions (befordringsfradrag)

Denmark has a progressive income tax system with municipal tax, health contribution via tax, labour market contribution (AM-bidrag) and, for higher incomes, top-bracket tax (topskat). For 2024, topskat is paid on personal income above approximately DKK 588,900 after AM-bidrag. If your business profit as main occupation pushes you above this level, you should factor this into your preliminary assessment to avoid large underpayments.

4. Labour market contribution (AM-bidrag) and personal income

Business profit in a sole proprietorship is treated as personal income for tax purposes. You pay 8% labour market contribution (AM-bidrag) on your business profit before income tax is calculated. When your business becomes your main occupation and the profit increases, AM-bidrag will make up a larger share of your total payments.

Make sure that your bookkeeping clearly separates business income and expenses so that your taxable profit is calculated correctly. This is essential for both AM-bidrag and income tax.

5. VAT (moms) obligations when activity increases

If your turnover from taxable activities exceeds DKK 50,000 over a 12‑month period, you must be VAT-registered. Many side businesses stay below this threshold, but when the business becomes your main occupation, you will often cross it.

When you move to main occupation, you should:

• Register for VAT if you expect to exceed DKK 50,000 in turnover within 12 months
• Check your VAT reporting frequency – many small businesses report quarterly, but higher turnover can lead to monthly reporting
• Ensure your invoicing, accounting system and documentation meet VAT requirements, including correct VAT rates and proper invoice information

If you are already VAT-registered, review whether your new level of activity and turnover requires a change in your reporting frequency or accounting setup.

6. Impact on social benefits and unemployment insurance (A-kasse)

Changing from side business to main occupation can affect your access to unemployment benefits (dagpenge) and other social benefits.

• Unemployment insurance (A-kasse) – if you are a member of an A-kasse as an employee, your rights can change when you become primarily self-employed. Many A-kasser have specific rules for self-employed members, including requirements for closing or significantly reducing the business to receive benefits.
• Public benefits – if you receive benefits such as early retirement pension (efterløn), cash benefits (kontanthjælp) or other income-dependent benefits, increased business income can reduce or eliminate these. You must report changes in income and work situation to the relevant authority or municipality.

Before you fully switch to self-employment as your main occupation, it is wise to contact your A-kasse and, if relevant, your municipality to clarify how your rights and obligations will change.

7. Pension contributions and long-term security

As an employee, pension contributions are often paid automatically by the employer, typically 8–12% of salary on top of your own contribution. When your sole proprietorship becomes your main occupation, this automatic saving usually disappears.

You should therefore consider:

• Setting up a private pension scheme (ratepension, livrente or aldersopsparing) through a pension provider or bank
• Paying regular contributions based on your expected annual profit
• Using the tax deduction for pension contributions within the applicable annual limits

Ignoring pension when you move to full-time self-employment can significantly weaken your financial security later in life, even if your current income is high.

8. Bookkeeping, deductions and business structure

When your business becomes your main occupation, the volume and complexity of transactions usually increase. This makes proper bookkeeping and documentation even more important.

Consider whether you should:

• Switch from simple spreadsheets to professional accounting software
• Formalise procedures for invoicing, expense handling and archiving of vouchers
• Review your use of deductions, including home office, car expenses, telephone, internet and other mixed-use costs

At this stage, many business owners also start considering whether remaining a sole proprietorship is still the best structure, or whether converting to a private limited company (ApS) would provide advantages in terms of liability, taxation and opportunities for reinvestment. Even if you stay as a sole proprietor, the fact that the business is now your main occupation justifies a more professional setup.

9. Insurance and risk management

As long as your business is a small side activity, you may have managed with minimal or no business insurance. Once it becomes your main occupation, your financial dependence on the business increases, and so does your risk exposure.

You should review:

• Professional liability insurance if you provide advice or services where errors can cause financial loss to clients
• Business contents and equipment insurance if you have significant tools, inventory or IT equipment
• Occupational injury insurance if you work with physical tasks or plan to hire employees
• Loss of earnings insurance (sygedagpengeforsikring for selvstændige) to secure income during illness

Some insurances are voluntary but highly recommended when the business is your main livelihood.

10. Practical checklist when your sole proprietorship becomes your main occupation

When you move from part-time side business to main occupation, you can use the following checklist as a guide:

1. Update your CVR information on Virk, including business description, industry code and address
2. Adjust your preliminary income assessment with Skattestyrelsen to reflect higher business profit and any reduced salary income
3. Register for VAT or review your existing VAT registration and reporting frequency
4. Clarify your rights and obligations with your A-kasse and, if relevant, your municipality
5. Set up or adjust pension contributions so you continue to save for retirement
6. Strengthen your bookkeeping system and documentation routines
7. Review and, where needed, expand your business insurance coverage
8. Consider whether remaining a sole proprietorship is still optimal, or whether you should plan for a later conversion to ApS

By handling these points proactively, you reduce the risk of unpleasant surprises and ensure that your transition from side business to main occupation in Denmark is both compliant and financially sustainable.

Updating Registration When You Hire Employees for the First Time (eIndkomst, ATP, Insurance)

Hiring your first employee in Denmark is a major step for a sole proprietor and it triggers a number of mandatory registration updates. You must register as an employer, report salaries through eIndkomst, pay labour market contributions and ATP, and ensure that you have the right insurance and agreements in place. Failing to update your registration correctly can lead to fines, back payments and problems with SKAT and other authorities.

Registering as an employer and updating your CVR data

Before your new employee starts working, you must register your sole proprietorship as an employer. This is done via Virk, where you update your CVR registration to indicate that you have employees. In the registration, you typically need to specify:

• That you will pay A-income (salary) to employees
• Whether you will withhold A-tax and AM-bidrag (labour market contribution)
• Whether you will be paying ATP contributions
• Whether you will have employees covered by collective agreements or special schemes

Once you are registered as an employer, SKAT and other authorities expect regular reporting and payments, even if you only have one part-time employee. If your situation changes later (for example, you no longer have employees), you must update your registration again to avoid unnecessary reporting obligations.

Setting up eIndkomst and payroll reporting

All salaries in Denmark must be reported electronically through the eIndkomst system. As a sole proprietor, you can either use a payroll system that integrates with eIndkomst or report manually via TastSelv Erhverv. For each pay period, you must report at least:

• Gross salary
• A-tax withheld
• AM-bidrag (8% labour market contribution)
• ATP contributions
• Any holiday pay and other taxable benefits

Most small employers choose a monthly pay cycle, but you can also pay and report more frequently. The key is that the eIndkomst report and the payment of withheld A-tax and AM-bidrag must reach SKAT by the statutory deadlines. Late reporting or payment can result in interest and surcharges.

Understanding AM-bidrag, A-tax and ATP

When you hire employees, you become responsible for withholding and paying several mandatory contributions:

• AM-bidrag (labour market contribution): 8% of the employee’s gross salary is withheld before A-tax is calculated. You report and pay this together with A-tax.
• A-tax: Income tax withheld from the employee’s salary based on their tax card. The rate depends on the employee’s personal tax card, so you must always obtain the correct tax information from SKAT before paying the first salary.
• ATP (Arbejdsmarkedets Tillægspension): A statutory pension contribution for employees. For most full-time employees, the contribution is a fixed amount per month, shared between employer and employee. You withhold the employee’s share from salary and pay the total to ATP.

These obligations do not depend on whether your business is part-time or full-time. As soon as you have an employee with A-income, you must handle these correctly and on time.

Mandatory insurance and workplace obligations

In addition to tax and pension, hiring employees usually requires you to take out certain insurances and comply with health and safety rules. Depending on your industry and the type of work, you may need:

• Workers’ compensation insurance (arbejdsskadeforsikring)
• Occupational injury and liability insurance
• Possibly additional insurance required by collective agreements or specific sectors

You must also ensure that your workplace complies with Danish working environment rules, including risk assessments, safety instructions and, where relevant, registration with Arbejdstilsynet. If you operate from your home, you may need to adjust your insurance and inform your insurer that employees will be working there.

Holiday pay, contracts and HR documentation

Hiring your first employee also changes your obligations in terms of contracts and record-keeping. Under Danish law, you must:

• Provide a written employment contract when the employment exceeds the minimum duration or hours threshold set by law
• Accrue and pay holiday pay according to the Danish Holiday Act, typically 12.5% of the holiday-qualifying salary if you use a holiday account scheme
• Keep accurate records of working hours, salary calculations, holiday pay, sick leave and other employment-related data

These records must be stored securely and in line with data protection rules, but also be available for inspection by authorities if requested. This is an important part of your overall registration and compliance as an employer.

Updating your registrations when your workforce grows or changes

Once you are registered as an employer, further changes in your staffing may require additional updates. For example, if you:

• Move from only having casual or student workers to permanent full-time employees
• Start using freelancers and need to distinguish between B-income and A-income correctly
• Enter into a collective agreement that affects pension, insurance or working hours

you may need to adjust your CVR registration, your ATP setup, your insurance policies and your payroll routines. It is important to review your registrations each time your employment pattern changes to ensure that your information with SKAT, ATP and other authorities remains accurate.

When to seek professional help

For many sole proprietors, the first hire is the point where payroll and employer obligations become too complex to manage alone. If you are unsure about eIndkomst reporting, ATP rates, insurance requirements or how to classify workers, it is often cost-effective to consult a Danish accountant or payroll specialist. They can help you set up correct procedures from the start, so your registration as an employer supports your growth instead of creating compliance risks.

Adjusting Your Registration After Significant Change in Turnover or Business Activities

Significant changes in your turnover or business activities are not just an internal matter – in Denmark they often trigger a duty to update your registration with Erhvervsstyrelsen and Skattestyrelsen. Keeping your CVR data and tax setup aligned with your real activity helps you avoid incorrect VAT (moms), wrong preliminary tax (forskudsskat) and potential penalties.

When a change in turnover requires an update

As a sole proprietor (enkeltmandsvirksomhed), you should review your registration when your annual turnover moves clearly above or below key Danish thresholds or changes pattern over time. In particular, you should reassess your setup when:

• Your 12‑month taxable turnover exceeds DKK 50,000 and you are not yet VAT registered
• Your turnover drops so much that you no longer expect to reach DKK 50,000 in any 12‑month period and you consider deregistering for VAT
• Your expected annual profit changes materially compared with the income you reported in your preliminary tax (forskudsopgørelse) – for example, a change of more than DKK 20,000–30,000 in expected profit
• Your income pattern changes from occasional assignments to stable, full‑time business activity

When your situation changes, log in to skat.dk with MitID and update your forskudsopgørelse so that your B‑income, business profit and expected deductions reflect the new level of activity. This helps ensure that your ongoing tax payments match your real income and reduces the risk of a large back payment when you receive your annual tax assessment (årsopgørelse).

Turnover changes and VAT (moms) obligations

If your taxable turnover over any rolling 12‑month period exceeds DKK 50,000, you must register for VAT via Virk.dk. This applies whether the increase comes from more customers, higher prices or expanding into new services. You must register no later than when you can see that the threshold will be exceeded, not only after it has happened.

Once registered, you must charge 25% VAT on most sales and report and pay VAT according to the frequency assigned by Skattestyrelsen. The reporting frequency is linked to your turnover:

• Many smaller sole proprietors report VAT quarterly
• Higher turnover businesses may be moved to monthly reporting
• Very small activities may in some cases be allowed half‑yearly reporting

If your turnover grows and Skattestyrelsen changes your VAT period, you will receive a notice in your Digital Post (e‑Boks). Always check the new deadlines and adjust your bookkeeping routines so you can submit VAT on time.

If your turnover falls and you no longer expect to reach DKK 50,000 in any 12‑month period, you can apply to deregister for VAT via Virk. Before deregistration is approved, you must submit a final VAT return and handle any adjustment of VAT on assets and inventory if relevant.

Changes in business activities and industry code (branchekode)

When you significantly change what you sell or how you operate, you may need to update your registered industry code (branchekode/NACE code) and business description in the CVR register. Examples include:

• Switching from pure consulting to also selling physical products or software licences
• Adding online trading (webshop) to a previously local, service‑based business
• Moving from hobby‑like creative work to structured commercial production and sales
• Starting to offer regulated services (for example, financial advice or health‑related treatments)

You can update your business activities and industry code via Virk.dk under your CVR registration. Having the correct code is important for statistics, potential sector‑specific rules, and in some cases for insurance and collective agreements if you later hire employees.

Impact on tax type and preliminary tax (forskudsskat)

A major increase in turnover usually means a higher profit – and therefore higher income tax. In Denmark, personal income tax is progressive, and your total tax burden can change substantially when your business becomes your main source of income.

When your business grows, you should:

• Update your expected business profit in your forskudsopgørelse at skat.dk
• Check whether you are paying sufficient B‑tax (B‑skat) and AM‑contribution (8% labour market contribution)
• Consider whether to use the virksomhedsordning or kapitalafkastordning if your situation meets the conditions and it is advantageous for you

If your turnover drops and you expect a much lower profit or even a loss, you should also update your forskudsopgørelse. This can reduce your ongoing tax payments and improve cash flow. Losses from your sole proprietorship can, under certain conditions, be offset against other personal income, which can lower your total tax for the year.

From side business to main occupation

Many Danish sole proprietors start with a small side business alongside employment or studies. When turnover grows and the business becomes your main occupation, you should adjust your registration and tax setup to reflect this. In practice, this often means:

• Updating your expected income from employment and business in your forskudsopgørelse
• Ensuring you are correctly registered for VAT if your turnover exceeds the threshold
• Reviewing whether you need business insurance, professional liability insurance or occupational injury insurance (if you plan to hire staff)
• Considering pension contributions and savings, as you may no longer have an employer‑funded pension scheme

A clear separation between private and business finances becomes more important as your turnover rises. Using a dedicated business account and structured bookkeeping makes it easier to document income and expenses if Skattestyrelsen requests information.

When turnover changes suggest a different company form

Very strong growth in turnover and risk exposure can be a sign that you should consider changing from a sole proprietorship to a limited liability company (for example, an ApS). While this is a separate process, the trigger often comes from:

• Consistently high annual turnover and profit
• Greater contractual and financial risks in your projects
• Plans to bring in partners or investors

Before you change company form, make sure your current sole proprietorship registration is fully updated. This makes the transition smoother and reduces the risk of errors in the transfer of assets, VAT and ongoing contracts.

Practical steps to adjust your registration

When you experience a significant change in turnover or activities, you can typically handle the updates in three places:

1. Virk.dk – to update CVR data such as business description, industry code, VAT registration status and, if relevant, other registrations (for example, import/export)
2. skat.dk – to update your forskudsopgørelse, expected profit, B‑tax and any scheme you use for business taxation
3. Digital Post (e‑Boks) – to monitor messages from Erhvervsstyrelsen and Skattestyrelsen confirming changes or informing you about new reporting obligations

Always save documentation of the changes you make and keep your bookkeeping aligned with your updated registration. This gives you a clear audit trail if authorities ask for clarification later.

How to Update Your NemKonto and Digital Mail (e-Boks) Settings When Your Business Changes

In Denmark, your NemKonto and Digital Mail (e-Boks) are central to how you receive payments and official messages related to your sole proprietorship. When your business circumstances change – for example, you move, change bank, alter your business structure or suspend your activity – you must ensure that both your NemKonto and Digital Mail settings are updated so you do not miss important information from SKAT, Udbetaling Danmark, municipalities or other authorities.

What NemKonto Is and Why It Matters for Sole Proprietors

NemKonto is the bank account that public authorities use to pay money to you. As a sole proprietor, you can have:

• a NemKonto linked to your CPR (personal) for private payments, and
• a NemKonto linked to your CVR for business-related payments (for example VAT refunds, tax refunds or subsidies).

If your business NemKonto is not updated, refunds from SKAT (for example negative VAT, moms) or other public payments may be delayed or fail, which can affect your liquidity. Authorities do not manually check whether your account is still valid – they simply pay to the NemKonto registered for your CVR.

How to Update Your Business NemKonto

You manage NemKonto settings through the official NemKonto self-service. For a sole proprietorship, you normally log in with your personal MitID and then select the CVR you want to manage.

1. Go to the NemKonto self-service via the official NemKonto website or through Virk.dk.
2. Log in with MitID and choose your sole proprietorship (CVR) if prompted.
3. Select the option to register or change NemKonto for your business.
4. Enter the new bank account number (reg. nr. and account nr.) that should receive public payments.
5. Confirm and save the change. In most cases, the new NemKonto is active the same day.

If you change bank, close an account or open a dedicated business account, you should update NemKonto immediately. Do not wait until you expect a refund. If the registered account is closed, payments may be returned to the authority and you will have to contact them to resend the money after you correct the NemKonto.

When You Must Review Your NemKonto Settings

It is good practice to review your NemKonto whenever you make structural or financial changes in your sole proprietorship, including when you:

• switch to a new bank or close an existing account
• separate private and business finances and open a new business account
• change from part-time side business to main occupation and expect higher VAT or tax refunds
• temporarily pause or reactivate your business
• convert your sole proprietorship to another legal form (for example ApS) and obtain a new CVR.

When you convert to a company (such as an ApS), the new company must have its own NemKonto linked to the new CVR. The NemKonto linked to your old sole proprietorship CVR does not automatically transfer.

Understanding Digital Mail and e-Boks for Your Business

Digital Mail is the system used by Danish public authorities to send you official messages. Most of these messages are delivered to your e-Boks or another approved digital mailbox. For a sole proprietorship, you typically have:

• Digital Mail for you as a private person (CPR), and
• Digital Mail for your business (CVR), which you access via MitID Erhverv or your personal MitID with business roles.

Authorities such as SKAT, Erhvervsstyrelsen, Udbetaling Danmark and your municipality send legally binding messages to your Digital Mail. This can include VAT deadlines, tax assessments, reminders, decisions on benefits, and control letters. If you do not read these messages, you can miss important deadlines, incur surcharges or lose rights to benefits.

How to Check and Update Your Digital Mail Settings

You manage your business Digital Mail primarily through e-Boks and Virk. When your business changes, you should check:

• who has access to the business mailbox
• which email addresses and phone numbers receive notifications
• whether forwarding rules are still relevant and secure.

To update settings in e-Boks for your sole proprietorship:

1. Log in to e-Boks with MitID and select your business profile (CVR).
2. Go to settings for the business mailbox.
3. Update contact information such as notification email and mobile number.
4. Review and, if necessary, change who has user access (for example your accountant or employees).
5. Check any forwarding rules and ensure they point to current, secure email addresses.

If you use another digital mailbox provider approved for Digital Mail, the steps are similar: log in on behalf of the business, review access rights and update contact details.

Updating Access When You Hire or Change Advisors

When you hire employees, change accountant or otherwise change who helps you with administration, you should review Digital Mail access. You can grant or revoke access in two main ways:

• via e-Boks user management for your business mailbox, and
• via MitID Erhverv roles and rights, where you assign rights to handle post and self-service on behalf of the business.

Ensure that only trusted persons have access to read and act on official messages. When cooperation with an advisor ends, remove their access immediately to protect confidential information and avoid confusion about who is responsible for responding to authorities.

Address Changes and Moving Abroad

When you change your business address in the CVR register via Virk, authorities will use the new address in their systems, but your Digital Mail remains your primary channel for official communication. You should still:

• log in to e-Boks for your business and verify that your notification email and phone number are up to date
• ensure that you can access MitID and Digital Mail from your new location, especially if you move abroad.

If you move abroad while keeping your Danish sole proprietorship, you are still obliged to receive and read Digital Mail. Make sure your MitID works from abroad and that your contact details in e-Boks are linked to channels you actually use (for example an international phone number and email you check regularly).

Pausing, Reactivating or Closing Your Sole Proprietorship

When you temporarily pause your business, you still keep your CVR and Digital Mail, and authorities may continue to send you messages (for example confirmations of zero VAT returns or control letters). In this situation you should:

• keep your MitID active and ensure you can log in to Digital Mail
• regularly check your business mailbox or set up reliable notifications.

When you permanently close your sole proprietorship and deregister the CVR, authorities may still send messages for some time, for example final tax assessments or confirmations of deregistration. Do not stop checking Digital Mail immediately after closure. Keep access until you are sure all final statements and decisions have been received and handled.

Security and Data Protection When Updating Settings

Both NemKonto and Digital Mail contain sensitive financial and personal data. When you update settings, consider the following:

• Only update NemKonto and Digital Mail through official websites (NemKonto, e-Boks, Virk, skat.dk) using MitID.
• Do not share your MitID with employees or advisors; instead, grant them appropriate roles via MitID Erhverv or user access in e-Boks.
• Review access rights at least once a year and whenever someone leaves your business or advisory team.

Keeping your NemKonto and Digital Mail settings accurate and secure is a key part of managing your sole proprietorship in Denmark. It reduces the risk of missed deadlines, lost payments and data breaches, and ensures that communication with Danish authorities remains smooth as your business evolves.

Special Considerations for Regulated Professions and Licensed Activities

Some types of one‑person businesses in Denmark are subject to special rules, permits and supervision. If you run a regulated profession or a licensed activity as a sole proprietor, you must coordinate both your general business registration (CVR, tax and VAT) and your sector‑specific authorisations whenever your circumstances change.

Regulated and licensed activities typically include, among others:

• Health professionals (e.g. doctors, dentists, chiropractors, physiotherapists, psychologists, nurses)
• Legal and financial services (e.g. lawyers, auditors, certain financial advisers)
• Real estate agents and property administrators
• Taxi and other commercial passenger transport operators
• Food businesses (restaurants, cafés, catering, food trucks, food production)
• Hairdressers, beauty clinics and tattoo studios
• Security services and alarm companies
• Trades requiring authorisation (e.g. electricians, plumbers, gas fitters)

Aligning CVR data with sector licences

When you update your sole proprietorship registration in the CVR, you must ensure that the information matches the data held by the relevant authority. In practice this means that when you change your business name, address, industry code (branchekode), ownership structure or scope of services, you often need to update at least two places:

• Your general registration via Virk (CVR, SKAT, VAT/moms)
• Your sector authority or licensing body (for example Styrelsen for Patientsikkerhed, Fødevarestyrelsen, Færdselsstyrelsen, Sikkerhedsstyrelsen or Erhvervsstyrelsen in its supervisory role)

If the information does not match, you risk warnings, orders to correct the data, or in serious cases suspension or withdrawal of your licence.

Health professionals and clinics

If you are a registered health professional running a sole proprietorship, your personal authorisation is managed through the Danish Health Authority and the Danish Patient Safety Authority. When you change clinic address, open or close a practice, add new treatment locations or change your business name, you must:

• Update your CVR registration with the new address and industry code if relevant
• Notify the health authorities of the new practice details, including any satellite clinics
• Ensure your professional liability insurance covers the new activities and locations
• Update information in sundhed.dk and any patient‑facing directories if applicable

Failure to keep practice details updated can affect your authorisation status and may have consequences for patient safety assessments and insurance coverage.

Food businesses and hygiene approvals

Restaurants, cafés, food trucks, catering businesses and food producers must be registered or approved by the Danish Veterinary and Food Administration (Fødevarestyrelsen). When you change your business in a way that affects food handling, you must:

• Update your CVR registration with the correct industry code and address
• Submit a change notification to Fødevarestyrelsen before you start operating under the new conditions
• Request a new inspection if your premises or production setup change significantly

Typical changes that trigger an update include moving to new premises, adding takeaway or delivery, starting food production instead of only serving ready‑made food, or expanding into online food sales. Your smiley report and inspection frequency are based on the registered activity, so it is important that the description is accurate.

Transport, taxi and passenger services

Commercial passenger transport, including taxi services, requires permits and compliance with specific rules overseen mainly by the Danish Transport Authority (Færdselsstyrelsen) and municipalities. When you update your sole proprietorship registration, pay special attention to:

• Changes in business address or operating area, which may affect municipal permits
• Adding or removing vehicles, which may require updates to vehicle permits and insurance
• Shifting from part‑time to full‑time operations, which can influence your obligations regarding driving and rest times, bookkeeping and tax

If you operate via a platform or dispatch centre, check whether your contract or platform registration also needs to be updated when your CVR data changes.

Trades requiring technical authorisation

Electricians, plumbers, gas installers and similar trades often need authorisation from the Danish Safety Technology Authority (Sikkerhedsstyrelsen). When you change your business details, you must ensure that:

• The authorised responsible person is correctly registered for your CVR number
• Your business address and contact details match across CVR and Sikkerhedsstyrelsen’s registers
• Your insurance and quality management systems cover any new types of work you undertake

If you stop offering a particular regulated service, you should deregister that activity with the authority to avoid unnecessary inspections and fees.

Professional secrecy, AML and ethical rules

Lawyers, auditors, real estate agents and certain financial advisers are subject to strict rules on confidentiality, anti‑money laundering (AML) and client due diligence. When you update your registration, consider whether the change affects:

• Your AML risk assessment and internal procedures
• Where and how you store client data and documents
• Who has access to confidential information, especially if you move to shared offices or hire staff

Significant changes, such as opening a new branch, starting to serve higher‑risk clients or expanding into cross‑border services, may require you to update your AML policies and notify your supervisory authority.

Impact of address and premises changes

For many licensed activities, the physical premises are part of the authorisation. When you move, expand or significantly rebuild, you may need:

• New or updated municipal permits (e.g. building permits, environmental approvals, signage)
• New fire safety and occupational health assessments
• Updated approvals from sector authorities that have inspected your previous premises

Do not assume that a licence automatically follows you to a new address. Always check whether the permit is tied to the person, the company, the location or a combination of these.

Changing or expanding your range of services

When you broaden your services within a regulated field, you may cross into activities that require additional authorisations. Examples include:

• A beauty clinic adding laser treatments or medical‑grade procedures
• A café starting in‑house food production or alcohol service
• A fitness instructor offering diet plans that qualify as health advice
• An IT consultant starting to provide regulated payment services or investment advice

In these cases you must both update your CVR industry code and verify with the relevant authority whether extra licences, insurance or qualifications are required before you start the new activity.

Cross‑border and online services

If you begin offering regulated services to clients in other EU/EEA countries or outside the EU, you may face additional requirements. Depending on your profession, this can include notification to foreign authorities, recognition of qualifications, or compliance with foreign consumer and marketing rules. When you update your registration to reflect cross‑border activity, review:

• Whether your Danish licence is valid abroad or only nationally
• Insurance coverage for services provided outside Denmark
• Any need to register for VAT in other countries when selling digital or regulated services

Documentation and inspection readiness

Whenever you change your registration as a regulated or licensed sole proprietor, keep clear documentation of:

• What changed (address, services, premises, staff, equipment)
• When the change took effect
• Which authorities and organisations you notified and how (Virk submissions, emails, forms)
• Updated permits, approvals, inspection reports and insurance policies

Authorities can request this documentation during inspections or in connection with complaints. Having a complete paper trail makes it easier to demonstrate compliance and avoid sanctions.

Because regulated professions and licensed activities involve multiple authorities and complex rules, it is often wise to seek professional advice before you implement major changes to your sole proprietorship. This helps you avoid unintentionally operating without the necessary approvals while your business evolves.

Record-Keeping Requirements When You Amend Your Registration Data

Whenever you change your sole proprietorship registration in Denmark – for example your business address, industry code (branchekode), VAT status or employment registrations – you must be able to document what you changed, when you changed it and on what basis. Proper record-keeping is not only a legal obligation; it also protects you in case of a tax audit, SKAT (Skattestyrelsen) control or disputes with customers, suppliers or authorities.

What documents you should keep when you update your registration

When you amend your registration data in the CVR register via Virk.dk or directly with SKAT, you should systematically save:

• Confirmation receipts from Virk.dk and other public self-service systems (for example, PDF confirmations or screenshots showing date, time and reference number)
• Copies of submitted forms and applications (for example, changes to VAT registration, payroll registrations, import/export registrations)
• Correspondence with authorities (Skattestyrelsen, Erhvervsstyrelsen, Udbetaling Danmark, municipality) related to the change
• Internal documentation that explains the change (for example, board or owner decisions, business plans, contracts, lease agreements, employment contracts)
• Updated agreements with banks, insurance companies, pension providers and key suppliers that reflect new business details
• Updated terms and conditions, website imprint and privacy policy if your legal or contact details have changed

Minimum retention periods you need to respect

For Danish sole proprietors, bookkeeping and documentation rules are primarily set by the Danish Bookkeeping Act and tax legislation. As a rule of thumb:

• Accounting and tax-related documentation (including evidence of registration changes that affect tax, VAT or payroll) must be kept for at least 5 years from the end of the financial year to which the material relates.
• Payroll-related documentation (eIndkomst reports, salary specifications, holiday pay calculations, ATP contributions and related registration changes) should also be kept for at least 5 years, and in practice many businesses keep them for up to 10 years to be safe in case of disputes.
• Contracts and long-term agreements (for example, leases, franchise agreements, major supplier contracts) that are directly connected to a registration change should be kept for the entire contract period and at least 5 years after termination.

If a change affects several years (for example, a shift from hobby to full business activity, or from non-VAT to VAT-registered status), keep all related documentation for the whole affected period plus 5 years after the last relevant year.

Linking registration changes to your bookkeeping

Every significant update to your registration should be traceable in your accounts. This makes it easier for you, your accountant and SKAT to understand your business history. In practice, this means you should:

• Note the effective date of each change (for example, the date you became VAT-registered or started employing staff) in your accounting system
• Align your bookkeeping periods and tax/VAT reporting with the new status (for example, changing VAT settlement frequency when your turnover crosses the relevant threshold)
• Store registration confirmations together with the financial documents they affect (for example, keep the VAT registration confirmation with the first VAT return where you start charging moms)
• Document any transitional arrangements, such as invoices issued before and after a change of VAT status, or payroll before and after registering as an employer

Digital vs. paper records

Danish rules allow you to keep your records digitally, on paper or as a combination, as long as they are complete, secure and easily accessible for authorities. For most sole proprietors, a digital approach is more practical:

• Download and archive all confirmations from Virk.dk, TastSelv Erhverv, eIndkomst and other systems as PDF files
• Organise them in clearly named folders (for example, “2026-Change-to-VAT-Registration” or “2025-Address-Change-CVR”)
• Ensure regular backups, preferably in at least two separate locations (for example, local drive and encrypted cloud storage)
• Maintain a simple index or log file that lists all major registration changes with dates and where the documentation is stored

If you receive physical letters that relate to a registration change, scan them and store them with your digital records, but keep the originals for at least the same retention period.

Data protection and access control

Registration changes often involve personal data, especially when you register employees, change contact persons or update ownership details. To comply with Danish data protection rules and the GDPR, you should:

• Limit access to your registration documents to people who actually need it (for example, you and your accountant)
• Protect digital files with strong passwords and, where possible, two-factor authentication
• Store sensitive documents (for example, CPR numbers, employment contracts, health-related information) in encrypted form or in a secure physical location
• Delete or anonymise data that is no longer needed once the legal retention period has expired, unless you have a clear legal basis to keep it longer

Practical checklist whenever you amend your registration

To keep your record-keeping consistent, follow the same routine each time you update your sole proprietorship registration:

1. Make a short written note describing the change, the reason and the effective date.
2. Submit the change via the relevant system (for example, Virk.dk, TastSelv Erhverv, eIndkomst).
3. Download and save all confirmations and receipts immediately.
4. File related documents together (contracts, correspondence, internal decisions).
5. Update your accounting system and, if relevant, your payroll and invoicing systems to reflect the new status.
6. Review whether the change affects your VAT, tax prepayments (B-skat), social contributions or insurance, and document any adjustments.

By treating every registration amendment as a formal event and documenting it carefully, you reduce the risk of errors in your Danish tax and VAT reporting, make potential audits smoother and create a clear, verifiable history of how your sole proprietorship has developed over time.

How Registration Changes Impact Social Benefits and Pension Contributions

Changes to your sole proprietorship registration in Denmark can directly affect your access to social benefits and the way you build up pension savings. Whenever your income level, working hours, municipality, or business status changes, you should consider how this impacts your social security coverage, contributions and future entitlements.

Link between your business registration and Danish social security

As a self-employed sole proprietor, you are generally covered by the Danish social security system on similar terms as employees, but the way contributions are paid and benefits are calculated is different. Your registration details and reported income influence in particular:

• Eligibility and level of unemployment benefits (A-kasse and efterløn)
• Sickness and maternity/paternity benefits
• Public pension (folkepension) and supplementary labour market pension schemes
• Social assistance and other income-tested benefits administered by your municipality

Unemployment insurance (A-kasse) and change of business status

If you are a member of an unemployment insurance fund (A-kasse) as a self-employed person, any change in your business registration can affect your right to dagpenge (unemployment benefits). Key situations include:

• Switching from side business to main occupation: When your sole proprietorship becomes your main source of income, you are normally considered self-employed for A-kasse purposes. To qualify for unemployment benefits later, you must document that you have ceased or significantly reduced the business, for example by deregistering for VAT (moms), closing the CVR registration or leasing/selling key assets.
• Reducing or pausing activities: If you temporarily pause your business (for example by setting it to inactive at Erhvervsstyrelsen), your A-kasse will assess whether you are still considered self-employed. This assessment affects whether you can be considered available for the labour market and receive benefits.
• Income thresholds: To qualify for unemployment benefits, you must meet an income requirement within a reference period. For self-employed, this is based on your taxable business income reported to SKAT, not on hours worked. If your turnover or profit changes significantly, your future benefit level may increase or decrease accordingly.

Always inform your A-kasse when you update your registration, especially when you change from part-time to full-time self-employment or when you plan to close or convert the business.

Municipality benefits and moving between municipalities or abroad

When you move to another municipality and update your business address, your case may be transferred to a new municipality (kommune). This can affect:

• Access to and administration of social assistance (kontanthjælp) and other income-tested benefits
• Rehabilitation, sickness benefits and integration services
• Local business support schemes or subsidies

If you move abroad and keep or close your Danish sole proprietorship, your coverage under the Danish social security system may change or end, depending on where you move and whether EU/EEA rules or bilateral agreements apply. In such cases, you should contact Udbetaling Danmark and your municipality before changing your registration to clarify your future coverage.

Sickness, maternity and paternity benefits for the self-employed

Your registration and reported income also influence your right to sickness and parental benefits:

• Sickness benefits: As a self-employed person, you normally receive sickness benefits from your municipality after a waiting period. You can choose to pay voluntary insurance contributions to reduce the waiting period. The benefit level is based on your documented income from the business.
• Maternity and paternity benefits: For barselsdagpenge, you must meet specific conditions regarding activity and income in your business. If you significantly reduce or close your business before or during the benefit period, this can affect your entitlement and the amount paid.

When you update your registration to reflect reduced activity, a pause or a change in working hours, you should check how this may influence any current or planned claims for sickness or parental benefits.

Public pension (folkepension) and income-tested supplements

Your sole proprietorship registration itself does not determine your right to the Danish state pension (folkepension), which is primarily based on residence. However, changes in your business income influence income-tested supplements, such as:

• Pension supplement (pensionstillæg)
• Personal supplement and housing benefits for pensioners

Business profits reported to SKAT are included when calculating whether you exceed the income thresholds for these supplements. If your turnover and profit increase after a registration change (for example, when you expand activities or move from side business to full-time), you may lose part of your income-tested supplements. Conversely, a reduction in business income may increase your entitlement.

Labour market contributions and pension build-up

As a sole proprietor, you pay the mandatory labour market contribution (AM-bidrag) of 8% on your business income before income tax. This contribution is part of the financing of the Danish welfare system and indirectly supports social benefits and public pensions, but it does not create an individual pension account for you.

Any significant change in your business activity or turnover that you register will therefore affect:

• The absolute amount of AM-bidrag you pay
• Your taxable income base for personal income tax
• The room you have for tax-deductible pension contributions

Private and occupational pension contributions as a sole proprietor

Unlike many employees, self-employed sole proprietors are not automatically enrolled in an occupational pension scheme with employer contributions. You must actively set up and fund your own pension. When your registration changes, you should reassess your pension strategy:

• Higher or more stable income: If your business becomes your main occupation and income increases, you may be able to increase your pension contributions. Contributions to private pension schemes are typically tax-deductible within specific annual limits, which are adjusted periodically.
• Lower income or temporary pause: If you reduce your activity or temporarily pause your business, you may need to lower or temporarily stop contributions. This can affect your long-term pension build-up and should be planned carefully.
• Switch to company form (e.g. ApS): If you later convert your sole proprietorship to an ApS, pension contributions can be paid as employer contributions from the company, which follows different tax rules than personal contributions as a sole proprietor.

Because tax rules and deduction limits for pension contributions are specific and change over time, it is advisable to coordinate major registration changes with a review of your pension plan.

Impact on early retirement and senior schemes

If you participate in or plan to participate in early retirement or senior schemes administered via A-kasse or Udbetaling Danmark, your status as self-employed and your business income are important factors. For example, to qualify for certain early retirement benefits, you may need to document that your business has been fully or substantially discontinued, which often requires deregistration or a clear reduction in activity in the official registers.

Practical steps when updating your registration

Whenever you make a significant change to your sole proprietorship registration, consider the following actions in relation to social benefits and pensions:

• Inform your A-kasse about changes in your business status, especially when shifting between side business and main occupation or when closing or pausing the business
• Notify your municipality if you receive or apply for income-tested benefits, sickness benefits or social assistance
• Review your pension contributions and savings plan in light of your new income level and risk profile
• Check how your updated income may affect any current or future public pension supplements
• Consult a Danish accountant or advisor if you are unsure how specific changes will affect your benefits and pension rights

By aligning your registration updates with a careful review of your social benefits and pension situation, you reduce the risk of unpleasant surprises and ensure that your business decisions support both your current security and your long-term financial future.

When and How to Temporarily Pause or Reactivate a Sole Proprietorship in Denmark

Many sole proprietors in Denmark experience periods where business activity slows down or stops temporarily. Instead of closing your sole proprietorship (enkeltmandsvirksomhed) completely, you can often pause it and later reactivate it. Understanding how this works in practice helps you avoid unnecessary tax, VAT (moms) and reporting obligations, while keeping the option open to restart.

What “pausing” a sole proprietorship really means

There is no formal legal status called “paused business” in Danish law. In practice, pausing means that you:

• Stop or significantly reduce business activity for a period
• Update your registrations so you are not treated as actively trading for VAT, payroll and certain tax purposes
• Keep your CVR number and business identity available for future use, unless you fully deregister the business

You can choose between:

• Keeping the CVR active but with no activity (e.g. deregistering VAT and employees, but not closing the business), or
• Fully deregistering the sole proprietorship and later starting a new one (which will normally get a new CVR number)

Typical reasons to pause a sole proprietorship

Common situations where pausing or temporarily scaling down makes sense include:

• Taking parental leave, sick leave or a longer break from work
• Accepting full-time employment and putting the side business on hold
• Seasonal businesses with long off‑seasons
• Studying or staying abroad for a period
• Testing a new business model before fully restarting

Key decisions before you pause your business

Before you change your registration, clarify:

• Will you have any turnover at all during the pause?
• Do you want to keep your CVR number visible in the CVR register?
• Are you currently VAT registered (momsregistreret)?
• Do you have employees registered in eIndkomst?
• Do you receive public benefits (e.g. dagpenge, kontanthjælp, efterløn) that are affected by business activity?

How to temporarily stop activity while keeping your CVR

If you expect to restart within a relatively short period, you can keep your sole proprietorship registered but “inactive” in practice.

1. Deregister for VAT (moms), if relevant

If your turnover drops to zero or stays clearly below the VAT registration threshold (currently 50,000 DKK over a 12‑month period), you can deregister for VAT via Virk:

1. Log in to Virk.dk with MitID Erhverv
2. Go to the form for “Ændre virksomhed” or “Afmeld virksomhed/registreringer”
3. Select that you want to deregister VAT (moms)
4. Enter the date when you stopped VAT‑liable activity

After deregistration you must:

• Submit a final VAT return up to the deregistration date
• Stop charging VAT on invoices issued after that date
• Stop deducting input VAT on new purchases (except in limited cases where costs relate to the winding‑down period)

2. Deregister as an employer, if you have employees

If you no longer have employees or pay A‑income, you must deregister as an employer:

1. Log in to Virk.dk
2. Choose the registration form for RUT/indberetning and employer registrations (often via “Registrering af virksomhed”)
3. Deregister as an arbejdsgiver from the date you paid the last salary

Remember to:

• Submit final eIndkomst reports for the last salaries
• Settle outstanding A‑tax, AM‑bidrag and ATP
• Adjust or cancel mandatory insurances (e.g. arbejdsskadeforsikring) if you have no employees

3. Inform SKAT about expected income

Your business income affects your preliminary income assessment (forskudsopgørelse). When you pause activity, update your expected income via TastSelv:

• Set expected business profit (overskud af selvstændig virksomhed) to 0 DKK or to a realistic low amount
• Adjust expected AM‑bidragsgrundlag and personal income accordingly

This helps avoid overpaying or underpaying tax and AM‑bidrag during the pause.

4. Keep accounting and record‑keeping in order

Even with no or low activity you must:

• Keep accounts and documentation for at least 5 years
• File your annual tax return (udvidet selvangivelse) if requested or if you have any business‑related income or expenses
• Be able to document that there was genuinely no activity if SKAT asks

How to fully deregister (close) your sole proprietorship

If you do not expect to continue the business, you can fully deregister it. This is more than a pause, but some owners choose this route and later start a new business.

Steps to close the business

1. Log in to Virk.dk
2. Use the function to “Afmeld virksomhed”
3. Deregister:
   • VAT (moms)
   • Employer registration (arbejdsgiver)
   • Any other registrations (excise duties, import/export, etc.)
4. Submit final:
   • VAT return
   • eIndkomst reports
   • Tax return including business income and any cessation gains (ophørsavance)

Once fully deregistered, your CVR will be marked as “ophørt” in the CVR register. To restart later, you usually create a new registration, which may result in a new CVR number.

How to reactivate a paused sole proprietorship

Reactivation depends on how far you went when pausing the business.

Scenario 1: You kept the CVR but deregistered VAT and employees

To restart activity:

1. Log in to Virk.dk
2. Use the form to change your registration (“Ændre virksomhed”)
3. Re‑register for:
   • VAT (moms), if you expect turnover above 50,000 DKK over 12 months or choose voluntary registration
   • Employer status, if you will have employees or pay A‑income
4. Update:
   • Business address, industry code (branchekode) and contact details if they changed
   • NemKonto and e‑Boks settings if needed

From the re‑registration date you must again:

• Charge and report VAT according to your reporting frequency (monthly, quarterly or half‑yearly)
• Report salaries in eIndkomst and pay A‑tax, AM‑bidrag and ATP on time
• Keep full bookkeeping records of all transactions

Scenario 2: You fully deregistered the sole proprietorship

If the business was closed, you reactivate by registering a new sole proprietorship:

1. Go to Virk.dk and choose to register a new sole proprietorship (enkeltmandsvirksomhed)
2. Provide:
   • Business name and address
   • Industry code (NACE/branchekode)
   • Expected turnover and whether you need VAT registration
   • Information about employees, if any
3. Receive your new or reactivated CVR number and registration confirmations

After registration, update your customers, suppliers, bank, insurance and any contracts with the new CVR details if they have changed.

Tax and benefit implications of pausing and reactivating

When you pause or restart your business, consider how it affects:

• Personal tax: Update your forskudsopgørelse so SKAT withholds the right amount of tax and AM‑bidrag.
• Top tax and church tax: Changes in business profit may move you above or below thresholds for top tax and affect your overall tax rate.
• Public benefits: Inform your unemployment fund (a‑kasse), municipality or Udbetaling Danmark if your business activity changes while you receive dagpenge, kontanthjælp, efterløn or pension‑related benefits.
• Pension contributions: If you pay into private or business‑related pension schemes, consider whether contributions should be adjusted when your income changes.

Practical tips for a smooth pause and restart

• Document the date you stop and restart activity (contracts, invoices, emails)
• Keep a simple overview of:
  • Which registrations you changed (VAT, employer, CVR status)
  • Which authorities you informed (SKAT, a‑kasse, municipality)
• Check deadlines for final VAT and tax filings when you pause, and for first filings when you restart
• Review your insurances (professional liability, contents, workers’ compensation) so you are neither over‑ nor under‑insured during the pause

Handled correctly, pausing and later reactivating a sole proprietorship in Denmark is straightforward. The key is to adjust your registrations on Virk, keep SKAT informed about expected income and maintain proper records throughout the inactive period.

Converting a Sole Proprietorship to an ApS or Other Company Form: Procedural Overview

At some point, many sole proprietors in Denmark consider converting their business into a limited liability company, most commonly an ApS (Anpartsselskab). The main reasons are usually limiting personal liability, attracting investors, or signalling a more established structure to customers and partners. However, the conversion is not automatic: you are essentially closing or transferring your sole proprietorship and starting a new legal entity with its own CVR number.

Below is a practical overview of how the conversion typically works in Denmark, what formalities you need to handle, and what to consider from a tax and compliance perspective.

1. Decide on the Target Company Form (ApS, A/S or Other)

For most small businesses, an ApS is the natural next step. Key features:

• Minimum share capital: 40,000 DKK in cash or eligible assets
• Limited liability: you are only liable up to the invested capital, unless you provide personal guarantees
• Separate legal entity: the company, not you personally, enters into contracts and owns assets

An A/S (Aktieselskab) requires at least 400,000 DKK in share capital and is usually relevant only for larger or investor-backed businesses. You can also consider other forms (e.g. I/S with a partner), but these do not provide the same level of limited liability as an ApS or A/S.

2. Choose the Method: Asset Transfer or Tax-Neutral Conversion

Converting a sole proprietorship to an ApS can be done in two main ways:

• Simple asset transfer: you establish a new ApS and sell or contribute the business assets to it at market value
• Tax-neutral conversion (skattefri virksomhedsomdannelse): you transfer the sole proprietorship to the ApS under specific rules in the Danish Tax Assessment Act (Virksomhedsomdannelsesloven), so that latent gains are not immediately taxed

The tax-neutral route is often preferred, but it requires that you meet a number of conditions, including:

• All assets and liabilities related to the business are transferred to the company
• The consideration you receive is primarily shares in the new company, not cash
• The conversion is carried out based on an opening balance sheet at fair value
• Formal deadlines and documentation requirements towards the Danish Tax Agency (Skattestyrelsen) are respected

Because the choice of method has long-term tax consequences (for example, on future sale of shares or assets), it is strongly recommended to obtain professional advice before deciding.

3. Prepare the Financial Basis for the Conversion

Before you can register the new company, you need a clear financial picture of the sole proprietorship. In practice this means:

• Preparing a closing balance sheet for the sole proprietorship at the conversion date
• Valuing assets such as inventory, equipment, goodwill, customer lists and possibly real estate at fair market value
• Listing all business-related liabilities, including loans, supplier debts and tax/VAT liabilities

If you contribute assets instead of paying the entire share capital in cash, you normally need a valuation statement from a state-authorised or registered public accountant to document that the non-cash contribution covers the required share capital. This is especially relevant when using the tax-neutral conversion model.

4. Establishing the ApS: Founding Documents and Registration

The next step is to formally create the new company via the Danish Business Authority (Erhvervsstyrelsen) on Virk.dk. You must prepare:

• A memorandum of association (stiftelsesdokument)
• Articles of association (vedtægter) describing company name, purpose, share capital, financial year, management structure and rules for general meetings
• Documentation for the paid-in share capital (bank confirmation or auditor’s statement for non-cash contributions)

When you submit the registration, you will receive a new CVR number for the ApS. This number will be used for all future registrations, invoices, contracts and tax/VAT reporting. The sole proprietorship’s CVR number will either be deregistered or limited to any remaining non-business activities, depending on your situation.

5. Transferring Assets, Contracts and Registrations

Once the ApS is registered, you must ensure that all practical and legal relationships are moved from you personally to the company. Typical steps include:

• Transferring customer and supplier contracts to the ApS, often via assignment agreements or new contracts
• Changing the name and CVR number on leases, insurance policies, telephone and internet subscriptions, software licences and other agreements
• Moving business bank accounts and payment solutions (e.g. card terminals, MobilePay Erhverv) to the ApS
• Transferring tangible assets (machinery, vehicles, inventory) and intangible assets (domain names, trademarks, software, goodwill) to the company

In many contracts, the counterparty must consent to the transfer, especially for leases and loan agreements. Banks and landlords often require updated financial information and may ask for personal guarantees, even if you operate through an ApS.

6. VAT (Moms) and Tax Registration for the New Company

The ApS must be registered separately for VAT and tax, even if your sole proprietorship was already registered. Through Virk.dk you should:

• Register the ApS for VAT (moms) if the expected annual turnover exceeds 50,000 DKK
• Register as an employer if the company will have employees, so you can report salary, A-tax and labour market contributions (AM-bidrag) via eIndkomst
• Register for any relevant industry-specific schemes (e.g. environmental fees or excise duties)

VAT and tax periods for the ApS may differ from those of your former sole proprietorship, depending on turnover. You must also ensure that the final VAT return and income tax for the sole proprietorship are filed correctly up to the conversion date.

7. Closing or Winding Down the Sole Proprietorship

After the transfer, the sole proprietorship will typically have no ongoing business activity. You should:

• Deregister the sole proprietorship’s VAT and employer registration on Virk.dk
• Submit final VAT returns and pay any outstanding VAT
• Prepare and file the last business tax return (udvidet selvangivelse) including the closing accounts

If you have used the Danish business scheme (virksomhedsordningen), special rules apply for how equity, loans and interest are handled at conversion. This can significantly affect your personal tax and should be reviewed with an accountant.

8. Updating NemKonto, Digital Mail and Public Information

The ApS must have its own NemKonto, which is usually linked to the company’s business bank account. You also need to:

• Ensure the ApS is correctly set up for Digital Post (e-Boks/Mit.dk) so you receive messages from public authorities
• Update business information on your website, invoices, email signatures and marketing materials with the new company name, CVR number and address
• Check that public registers (e.g. CVR, Branchenavne, possibly industry-specific registers) show the correct data

9. Accounting, Annual Report and Corporate Obligations

Unlike a sole proprietorship, an ApS must comply with the Danish Companies Act (Selskabsloven) and the Annual Accounts Act (Årsregnskabsloven). This means:

• Keeping double-entry bookkeeping and separate accounts for the company
• Preparing an annual report that complies with the relevant reporting class and filing it with Erhvervsstyrelsen within the statutory deadline after the end of the financial year
• Holding at least one annual general meeting where shareholders approve the accounts and decide on profit distribution

Depending on the size of the company, you may be exempt from mandatory audit, but you still need to meet all bookkeeping and reporting requirements. Mixing private and company funds is not allowed; all transactions between you and the company must be documented as salary, dividends, loans or reimbursements according to the rules.

10. Key Strategic and Tax Considerations Before You Convert

Before you initiate the conversion, it is worth clarifying a few strategic points:

• Whether your current and expected turnover, risk level and financing needs justify the extra administrative burden of an ApS
• How you plan to pay yourself from the company (salary vs. dividends) and the combined effect on income tax and company tax
• Whether a tax-neutral conversion is possible and beneficial in your specific situation
• How existing loans, leasing contracts and guarantees will be handled when the business moves into a company

A well-planned conversion can significantly strengthen your legal protection and make it easier to grow the business, but only if the process is carried out correctly in terms of registration, contracts and tax. For most owners, involving an accountant with experience in Danish company conversions is a cost-effective way to avoid errors that can later lead to unexpected tax bills or legal issues.

Data Protection and Privacy Considerations When Updating Public Business Information

When you update your sole proprietorship registration in Denmark, many of the changes you submit become visible in public registers such as the CVR register. At the same time, you are required to comply with the General Data Protection Regulation (GDPR) and Danish data protection rules. Understanding what is public, what must be protected, and how to handle personal data correctly is essential for both your own privacy and that of your customers, suppliers and employees.

Which business information is public in Denmark?

For sole proprietors, the CVR register generally publishes:

• Business name (including your own name if it is part of the business name)
• CVR number
• Business address and any production or branch addresses
• Industry code (branchekode/NACE code)
• Contact details such as phone number, website and email if you provide them as business contact data
• Information about VAT (moms) registration and registration for payroll tax (lønsumsafgift)

These data are considered business information and are normally accessible to the public via virk.dk and cvr.dk. You cannot make your CVR number or business address fully private, but you can often choose which contact details you publish and which you keep for internal or tax purposes only.

Protecting your private address and contact details

If you run your sole proprietorship from your home address, you should be aware that this address will usually appear in the CVR register. To protect your privacy, consider:

• Using a separate business address, such as an office hotel, co-working space or c/o address, if this is practically and legally possible for your type of business
• Registering a dedicated business phone number and email address instead of using your private ones
• Ensuring that the contact details you submit to SKAT and other authorities as “internal” are not automatically reused as public CVR contact information

If you have a protected address (adressebeskyttelse) in the Danish civil registration system, special rules may apply. In that case, you should contact Erhvervsstyrelsen or a professional advisor before updating your registration to avoid unintentionally publishing sensitive address information.

Handling personal data when you update your registration

When you change your registration, you may need to submit personal data about yourself and others, for example:

• Your own CPR number when you log in with MitID
• Details about employees when registering as an employer (eIndkomst, ATP, holiday pay schemes)
• Information about co-owners or key persons if relevant for your business

Under GDPR, you must ensure that any personal data you provide are:

• Collected for a clear and lawful purpose (e.g. tax, VAT, employment registration)
• Limited to what is necessary for that purpose
• Accurate and kept up to date
• Stored securely and only for as long as required by law or business needs

Authorities such as SKAT and Erhvervsstyrelsen are themselves data controllers for the information you submit through their systems. However, you remain responsible for how you store and use copies of documents, confirmations and correspondence in your own accounting and business systems.

Minimising unnecessary personal data in public fields

Many registration forms contain free-text fields, for example for business descriptions or additional information. To protect privacy and comply with GDPR, avoid entering unnecessary personal data in these fields, such as:

• Full names and contact details of private individuals who are not required to be listed
• Health information or other sensitive personal data about yourself, employees or customers
• CPR numbers, bank account numbers or NemKonto details

Keep detailed personal information in your internal records and accounting systems, not in public registration texts. If you accidentally submit personal data in a public field, contact Erhvervsstyrelsen as soon as possible to request correction or removal.

GDPR responsibilities when your business changes

Changes in your sole proprietorship registration often mean changes in how you process personal data. Typical examples include:

• Hiring employees for the first time and registering as an employer
• Starting online sales with customer accounts and newsletters
• Expanding into new services that require more detailed customer information

In these situations, you should review your GDPR compliance, including:

• Updating your privacy policy so it reflects your actual data processing activities
• Ensuring you have valid legal bases for processing (e.g. contract, legal obligation, consent)
• Checking that your data processors (e.g. cloud accounting, payroll, CRM, newsletter tools) have proper data processing agreements and store data within the EU/EEA or under valid transfer mechanisms
• Adjusting access rights and internal procedures so only relevant staff can see sensitive information

Public business information vs. confidential tax and payroll data

It is important to distinguish between:

• Public business data in CVR and on virk.dk
• Confidential data submitted to SKAT, ATP, Udbetaling Danmark and other authorities

Your VAT returns, income tax information, payroll data and detailed financial statements for a sole proprietorship are not automatically public, even though they are submitted digitally. Always use secure channels such as TastSelv Erhverv, e-Boks and authorised accounting or payroll systems when sending or receiving this type of information.

Data security when using NemID/MitID, NemKonto and e-Boks

When you update your registration, you typically use MitID, NemKonto and e-Boks. To protect your data:

• Never share your MitID login or codes with employees, bookkeepers or others; instead, grant them separate roles and authorisations via virk.dk and TastSelv
• Regularly review who has access to your business’s digital mail (e-Boks) and remove access for people who no longer work with you
• Ensure that your NemKonto is linked to a business account that is not used for private payments, reducing the risk of mixing business and personal data

Retention periods and deletion of data after changes

When you change your registration, you create new documents, confirmations and correspondence that contain personal and business data. Under Danish bookkeeping rules, you must generally keep accounting records, vouchers and related documentation for five years. In some cases, labour law or tax rules may require longer retention for specific types of data.

At the same time, GDPR requires that you do not keep personal data longer than necessary. A practical approach is to:

• Follow the statutory retention periods for accounting and tax documentation
• Regularly review older files, emails and backups and delete data that are no longer needed and not subject to a legal retention requirement
• Document your retention policy so you can demonstrate compliance if the Danish Data Protection Agency (Datatilsynet) asks

Correcting mistakes and exercising data subject rights

If you discover that your public business information is incorrect or reveals more than you intended, you should correct it as soon as possible via virk.dk or by contacting Erhvervsstyrelsen. Under GDPR, individuals also have rights such as access, rectification and, in some cases, erasure of their personal data.

As a sole proprietor, you must be prepared to handle such requests from customers, employees or other individuals whose data you process. This includes being able to:

• Explain what data you hold and why
• Correct inaccurate information without undue delay
• Restrict or delete data when you no longer have a legal basis to keep them

When to seek professional advice on data protection

If your business handles large volumes of personal data, sensitive information, or operates in a regulated sector (for example health, finance or childcare), data protection issues can quickly become complex. In such cases, it is often wise to consult an accountant or legal advisor with experience in Danish GDPR compliance before making major registration changes or implementing new systems.

By combining accurate, up-to-date public registration with robust data protection practices, you can meet your legal obligations in Denmark while safeguarding both your own privacy and the rights of the people whose data you process.

When to Seek Professional Help: Accountant vs. Legal Advisor in Complex Changes

Not every change to your Danish sole proprietorship requires professional support. Updating your address or phone number in the CVR register is usually straightforward. However, once your situation affects tax, VAT (moms), employees, or legal risk, it is often safer and more cost‑effective to involve a specialist. In Denmark, that usually means choosing between an accountant (revisor/bogholder) and a legal advisor (advokat). In more complex cases, you may need both.

When an accountant is the right first choice

An accountant or experienced bookkeeper is typically your main partner when your registration changes have financial or tax consequences. You should strongly consider using an accountant when:

• Your turnover approaches or exceeds the VAT registration threshold (currently 50,000 DKK over a 12‑month period) and you are unsure how and when to register for moms with Skattestyrelsen.
• You change business activities or industry code (branchekode/NACE) and are unsure how this affects deductions, VAT rates, or special schemes (for example, mixed activities with both VAT‑liable and VAT‑exempt services).
• You move from hobby‑like activity to a real business and need to clarify whether Skattestyrelsen will treat your activity as erhvervsmæssig virksomhed, including rules on loss deductions and business schemes.
• Your turnover increases significantly and you are considering the Danish business tax schemes such as virksomhedsordningen or kapitalafkastordningen, or you want to optimise between personal income, AM‑bidrag (8%), and capital income.
• You start paying A‑income or B‑income to others and must register as an employer in eIndkomst, calculate A‑tax, AM‑bidrag, and possibly ATP contributions.
• You have cross‑border elements (customers or suppliers abroad, or you move to or from Denmark) and need to understand Danish tax residency, double taxation agreements, and VAT on international services and goods.
• You are late with updates or filings and risk interest, surcharges, or estimated assessments from Skattestyrelsen.

An accountant will typically help you:

• Update your registration in TastSelv Erhverv and on Virk.dk (CVR data, tax, VAT, employer registration)
• Set up or adjust your bookkeeping system to reflect the new structure
• Estimate and plan your B‑tax (B‑skat) and on‑account tax payments
• Prepare annual accounts that match your updated registration and chosen tax scheme

When you should talk to a legal advisor (advokat)

A legal advisor is more relevant when your changes create legal risk, contract issues, or regulatory obligations that go beyond pure tax and accounting. You should consider an advokat when:

• You plan to convert your sole proprietorship to an ApS or another company form and need to understand liability, transfer of assets, and whether a tax‑free restructuring is possible.
• You enter into complex contracts with customers, suppliers, agents, or partners that may affect your liability or intellectual property, and you want to ensure your business name and registration match your contractual obligations.
• You operate in a regulated profession or licensed activity (for example, financial services, healthcare, transport, food, or construction areas with special permits) and must align your CVR registration with sector‑specific rules.
• You change ownership or control in practice (for example, a spouse or partner starts working in the business, profit‑sharing agreements, or silent partners) and need to clarify what is legally allowed within a sole proprietorship.
• You face disputes, claims, or inspections from authorities, customers, or employees, and your registration data or past changes may be part of the case.
• You process personal data in a new way (for example, new online services, customer portals, or international data transfers) and must ensure your public information, privacy policy, and internal procedures comply with GDPR and Danish data protection rules.

A legal advisor can help you assess risk, draft or adjust contracts, and ensure that the way your business is registered matches how you actually operate, so you do not unintentionally assume personal liability or violate sector‑specific regulations.

Situations where you may need both

Some changes affect both your legal position and your tax or VAT situation. In these cases, coordination between an accountant and a legal advisor is often the safest approach. Typical examples include:

• Converting from sole proprietorship to ApS, especially if you transfer assets such as goodwill, inventory, or property and want to minimise tax while securing limited liability.
• Entering into cooperation agreements or joint ventures where you remain a sole proprietor but share revenue, costs, or intellectual property with others.
• Large changes in turnover or business model (for example, moving from local consulting to an online platform or subscription service) that raise both VAT and contract/privacy questions.
• Relocating abroad while keeping your Danish sole proprietorship active, which can affect tax residency, social security, and legal jurisdiction in contracts.

How to prepare before contacting a professional

To keep costs under control and get precise advice, prepare clear information before you contact an accountant or legal advisor. It is helpful to gather:

• Your current CVR number and registration details from cvr.dk or Virk.dk
• Recent financial data: turnover, main expense categories, and expected changes
• Any letters or decisions from Skattestyrelsen, Erhvervsstyrelsen, or other authorities
• Draft contracts, cooperation proposals, or descriptions of new services or markets
• Your goals: for example, reduce risk, limit tax, prepare for hiring, or prepare for incorporation as ApS

The clearer you can describe your planned change, the easier it is for the advisor to tell you whether a simple registration update is enough, or whether you need a more thorough restructuring.

Choosing the right advisor for your Danish sole proprietorship

When selecting an accountant or legal advisor in Denmark, look for professionals who:

• Have concrete experience with Danish sole proprietorships and small businesses
• Understand the interaction between CVR registration, tax, VAT, and social benefits
• Are familiar with the digital systems you must use (Virk, TastSelv Erhverv, eIndkomst, NemKonto, e‑Boks)
• Can give you a clear estimate of costs and scope before starting the work

For many sole proprietors, an ongoing relationship with an accountant and occasional targeted input from a legal advisor is enough to keep the business compliant and flexible as circumstances change. The key is to seek help early, before a registration change creates tax problems, legal disputes, or unexpected personal liability.
