What Documents Do You Need to Open a Sole Proprietorship in Denmark?

Understanding the Danish Sole Proprietorship (Enkeltmandsvirksomhed)

A sole proprietorship in Denmark, known as an enkeltmandsvirksomhed, is the simplest formal business structure for an individual. You and the business are legally the same entity, which means there is no separate company capital requirement and no separate legal personality. Because the structure is so straightforward, the list of documents required is shorter than for limited companies, but there are still several indispensable items you must have ready before you can register and operate properly.

In Denmark, most of the process is digital and goes through public portals such as Virk.dk and TastSelv on skat.dk. Therefore, many of the “documents” you need are, in practice, digital credentials, identification numbers, and well‑prepared information rather than paper forms. Ensuring you have these in place before starting the registration will save you time and prevent frustrating rejections or delays.

Personal Identification: CPR Number and Valid ID

The absolute foundation for opening a sole proprietorship in Denmark is your personal identification. Because the business is linked directly to you as a private person, the authorities use your personal details to create and connect your business registration.

First, you must have a Danish Civil Registration Number (CPR‑nummer). For Danish residents, this is already assigned and appears on your yellow health insurance card (sundhedskort). For foreign residents moving to Denmark, obtaining a CPR number typically requires registering your address and residence rights with the local municipal office (Borgerservice). Without a CPR number, you cannot proceed with the standard digital registration process for an enkeltmandsvirksomhed.

In addition to the CPR number, you should have a valid form of ID available, such as a passport or national ID card. While you will not normally upload a scan of this during the online registration on Virk.dk, you may need it when you visit your bank, when you apply for MitID (or similar identification), or if the authorities request further verification. Banks in particular are strict about identity verification under “Know Your Customer” and anti‑money‑laundering rules, so an updated, unexpired passport or ID card is extremely helpful.

NemID / MitID and NemKonto Documentation

Because almost all official interactions in Denmark are conducted digitally, having the correct digital identity tools is essential. Historically, NemID was used, but it is being replaced by MitID. Regardless of name, you will need one of these secure login solutions to access:

- Virk.dk for business registration

- skat.dk (TastSelv Erhverv) for tax matters

- e‑Boks for official digital mail

To obtain MitID, you usually need your CPR number, valid ID, and sometimes a Danish address. The procedure may vary depending on your residency status and whether you are already registered in Denmark, but banks or designated MitID agents typically handle the registration. Treat your MitID credentials with the same care as your physical ID; without them, you cannot submit or amend registrations for your business.

Additionally, you must have a NemKonto. A NemKonto is a regular Danish bank account that has been designated as your official account for receiving public payments and tax refunds. For a sole proprietorship, your personal NemKonto is usually used, although some business owners designate a separate business account. The key document here is confirmation from your bank that an account is open in your name. While you may not upload this during registration, you will need it if there are any issues and to ensure that the Danish Tax Agency (Skattestyrelsen) can make transfers correctly.

Business Name and Address Details

Another crucial area of information concerns the identity of your business itself. At registration, you must provide:

- Your chosen business name (virksomhedsnavn)

- The business address (virksomhedsadresse)

The business name does not always require separate documentation, but it must comply with Danish naming rules. Your personal name can always be used; however, if you choose a distinctive trade name or brand, it must not be misleading or identical to an existing registered company in the same field. Before registering, you should check the Central Business Register (CVR‑registret) via Virk.dk for existing names. While there is no formal “document” to upload, it is wise to keep a record of your name searches and decisions for your own files.

For the business address, you will typically use your residential address, especially for small freelancers or consultants. If your business operates from a different location, such as rented office space or a shop, you should have a lease agreement or written permission from the property owner that allows you to use the address as a business location. This lease or agreement may not be uploaded during the basic registration, but it is an important document in case the municipality or landlord requests proof that commercial use is allowed.

Industry Code (Branchekode) and Activity Description

When you register the sole proprietorship through Virk.dk, you must select an appropriate industry code (branchekode, often referred to as NACE code) and briefly describe your business activities. This may not sound like a traditional “document”, but in practice you should prepare these details in advance as a written description.

Your activity description should clearly state what you will be doing, for example:

- “Freelance graphic design and digital illustration services for businesses”

- “Retail sale of clothing via an online webshop”

- “Small‑scale carpentry and repair services for private households”

Choosing the correct industry code is more than an administrative detail. It can influence how the tax authority evaluates your income, which sector regulations might apply, and what statistical category your company appears in. To avoid confusion or later changes, prepare a short written description of your activities and note the most accurate NACE code after researching on the Danish Business Authority's website or through the CVR register. Keeping this description as a document in your records ensures consistency if you are asked to explain your business by your bank, accountant, or the tax office.

Tax and VAT Registration Information

When starting a sole proprietorship, you must consider which tax registrations apply to you. The most common are:

- Registration as a business for income tax purposes

- Registration for VAT (moms), if your turnover exceeds the threshold

- Registration as an employer, if you plan to hire staff

You will not typically upload separate “tax documents” at the time of registration, but you must have certain information ready. This includes an estimate of your expected annual turnover, whether you expect to trade with foreign customers, and whether you will import or export goods or services. These estimates help determine whether you must register for VAT from the start and what deadlines apply for filing VAT returns.

If you are already registered with skat.dk as a private individual using TastSelv, you will access the same system but will now also manage business‑related tax matters. It is wise to keep a written projection of your expected income and expenses for the first year. While this is not a formal document requested at registration, it is extremely helpful when answering questions about VAT registration and planning your preliminary tax (B‑skat, if applicable).

Bank Account and Financial Documentation

Although Danish law does not strictly require a separate business bank account for a sole proprietorship, many banks and accountants strongly recommend it for clarity and bookkeeping. Opening a business account may require additional documentation beyond what is needed for the basic registration of the sole proprietorship.

Banks often ask for:

- Proof of identity (passport or ID card)

- CPR number and address documentation

- Description of the business activities (the same document you prepared for registration)

- Expected annual turnover and typical transaction sizes

- Information about suppliers, customers, and whether you will trade internationally

Some banks request a simple business plan or written summary explaining why you are opening the account and how the business will operate. While this is not mandated by the Danish Business Authority, it is an informal requirement from many financial institutions to meet compliance obligations. Preparing a concise document that outlines your services, expected customer types, and forecast turnover will make the bank process smoother and can double as a reference document for your own planning.

Accounting and Record‑Keeping Preparations

Danish law requires that you keep orderly accounts and documentation of all business transactions. Even for a small sole proprietorship, you need a robust system for handling invoices, receipts, and other financial records.

Before or soon after registration, you should prepare:

- A consistent invoicing template that includes your name, business name, CVR number (once assigned), address, and VAT details if applicable

- A method for storing receipts and invoices, whether digital or paper based, in a way that can be presented to the tax authority on request

- Bank statements for the account(s) connected to the business

These items may not be requested on the day you register your enkeltmandsvirksomhed, but they are, in practice, essential documents for running a compliant business. Invoices and receipts must be kept for several years; failing to maintain them properly can cause problems during a tax inspection. Many small business owners choose an accounting system or app in advance and configure the templates so that from the very first sale, their invoices meet Danish requirements.

Special Permits and Sector‑Specific Documentation

Some types of activity require additional permits, authorisations, or registrations beyond the standard sole proprietorship registration. Whether you need such documents depends entirely on your sector and activities. Examples include:

- Serving alcohol or operating a restaurant may require municipal permits and food safety approvals from the Danish Veterinary and Food Administration (Fødevarestyrelsen)

- Health and care services might require professional authorisation or municipal approval

- Certain construction or technical trades may require certification or registration under specific regulations

Each of these areas involves its own application process and documentation, such as diplomas, proof of qualifications, lease agreements for premises, or safety plans. If your planned activity falls into a regulated area, you should research these requirements early and compile the necessary documents so you can apply for the permits in parallel with your business registration. Keeping copies of all permits in a dedicated folder is essential, since they may have to be shown to inspectors or renewed periodically.

Bringing It All Together in Practice

In practical terms, opening a sole proprietorship in Denmark revolves around preparing a focused set of personal documents, digital credentials, and well‑structured information about your business. The core elements include your CPR number and ID, access to MitID and NemKonto, a clear business name and address, a carefully chosen industry code and activity description, and an understanding of your tax and VAT obligations. Around this core, your bank may require additional written descriptions or simple plans, and your specific sector might demand separate permits or authorisations.

By approaching the process systematically, treating each of these items as part of a coherent documentation package rather than isolated requirements, you can move through the digital registration on Virk.dk with confidence and start operating your enkeltmandsvirksomhed without unnecessary administrative obstacles.

Opening a sole proprietorship (enkeltmandsvirksomhed) in Denmark is relatively straightforward compared with many other business forms, but the process is still document‑driven and highly structured. Understanding which documents are required at each step will save you time, reduce the risk of rejection from the authorities, and help you start trading legally from day one. This guide walks carefully through all the key documents you typically need, from personal identification to tax and banking paperwork, and clarifies where the requirements differ for residents, EU/EEA citizens, and non‑EU nationals.

Core Personal Identification: CPR, NemID/MitID and Address

The foundation of any Danish sole proprietorship registration is the personal identity of the owner. A sole proprietorship is not a separate legal entity; it is legally identical to you as a private person, so the authorities rely entirely on your personal data.

The first document you must have is a valid Danish Civil Registration Number (CPR‑nummer). This is your unique personal ID in Denmark, and it appears on your yellow health insurance card. Without a CPR number, you cannot complete digital registration via the Danish Business Authority's platform (Virk.dk) in the ordinary way. The CPR number connects your business activities directly to your personal tax profile, social security, and public records.

Closely tied to this is your NemID or its successor, MitID. Although not a “document” in the traditional sense, NemID/MitID is a digital identity and login solution used to sign forms, submit registrations and access both SKAT (the Danish Tax Agency) and the Danish Business Authority. For the purposes of setting up a sole proprietorship, your NemID/MitID functions as your electronic signature, replacing the need for handwritten signatures on many forms. You must therefore have:

- An active NemID/MitID linked to your CPR number

- Access to the authentication app or key card

- Up‑to‑date contact details in your NemID/MitID profile

You will also need proof of your registered address in Denmark, because official communication from the authorities often relies on your civil registration address and your digital mailbox (e‑Boks). Usually this is not a separate document you submit, but the address stored under your CPR. However, if you plan to use your home address as your business address, be prepared for banks or specific authorities to ask for evidence such as a housing contract, rental agreement or recent utility bill, especially if your residential status is relatively new or if you are a foreign national.

Documents for Foreign Nationals Without a Danish CPR Number

If you do not yet have a Danish CPR number, the documentation requirements change and become more paper‑based and manual. In such cases, you cannot use the standard fully digital procedure and may need to proceed via special forms or contact the Danish Business Authority directly.

Foreign nationals typically must present:

- A valid passport (copy of the identity page in colour)

- Any existing national ID card from an EU/EEA country (if applicable)

- Documentation of lawful residence in Denmark or another EU/EEA state (residence card, work and residence permit, registration certificate, or similar)

Where you lack a CPR number, the authorities may assign a temporary identification or use an alternative reference in their systems. You may be asked to fill in specific registration forms in PDF format and submit them with scanned identification. For non‑EU citizens, residence and work permits issued by the Danish Immigration authorities are essential, as they demonstrate that you are legally allowed to carry out independent business activities. It is important that the wording of your permit does not restrict you solely to one employer or prohibit self‑employment.

If you reside abroad but wish to register a Danish sole proprietorship, the Danish Business Authority may require:

- Proof of foreign address (utility bill, bank statement, or local registration document)

- Tax identification number (TIN) or equivalent from your home country

- Any relevant documentation justifying a business presence in Denmark, such as contracts with Danish clients or a lease for a Danish office or warehouse

In these more complex constellations, document requirements can vary, so always verify the latest instructions on Virk.dk and be prepared for the authorities to request additional supporting material.

Business Name, Purpose, and Address Confirmation

Once your personal identity is documented, the next step focuses on the business itself. The Danish Business Authority needs clear information about your trade name, activities, and address. While not all of these are “documents” in the classic sense, you will often be required to support them with written or digital evidence, especially when banks or local authorities become involved.

You should prepare:

- The chosen business name (virksomhedsnavn), including any alternative names or trading names

- A brief but precise description of the business purpose (formål), such as “web design services,” “small‑scale catering,” or “consultancy in marketing”

- A primary business address in Denmark, which can be your home address or commercial premises, depending on zoning and lease permissions

If you use a rented commercial space, keep the lease agreement at hand, as banks and in some cases municipal authorities may request a copy to verify that you are permitted to conduct commercial activities there. If you operate from home, and particularly from a tenant apartment, some landlords include clauses about running a business from the property. Having your rental contract available is therefore prudent, even if it is not explicitly required by the Danish Business Authority during online registration.

Note that if your planned business name suggests regulated activities (for example, using words like “bank,” “insurance,” or “investment”), additional approvals or documentation might be necessary to demonstrate that you are entitled to use such terms. This is less common for basic sole proprietorships, but it underlines why you should keep all relevant contracts, licences, and permissions in a structured, accessible format.

Central Business Registration (CVR) and Digital Forms

Registering for a CVR number is the formal step that turns your sole proprietorship into a recognised business in Denmark. The registration is done digitally through Virk.dk, most commonly using your NemID/MitID. During this process, you complete an online form that effectively becomes the central “document” describing your business.

The online form requires you to provide:

- Your personal identity details (CPR, full name, contact information)

- Business name and any secondary names

- Business address and, if applicable, postal address

- Date when the business activity starts

- Description of main business activity, typically via an industry code (branchekode/NACE code)

- Indication of whether you will have employees from the start

- Information on expected turnover, relevant for VAT registration

Once submitted and approved, the system issues your CVR number. The output from this process is an electronic registration certificate, which you can download or print. This CVR registration extract (often called a CVR report or company profile) functions as an important document for later dealings with banks, suppliers and public authorities, as it proves your formal business status.

Although the initial application is online, many institutions still request a PDF or printed copy of your CVR registration as supporting documentation. It is wise to save the confirmation email and the registration extract in both digital and physical form as part of your core business document pack.

Tax‑Related Documentation: SKAT, VAT and Income Tax

Tax documentation is another central pillar in establishing your sole proprietorship. From the moment you register, SKAT needs to know how your business income will be taxed and whether you will be registered for VAT (moms), payroll taxes, or other schemes.

When registering your business, you typically complete an integrated tax registration form via Virk.dk that feeds into SKAT's systems. In that form and subsequent tax processes, you will be asked for:

- An estimate of your expected annual turnover

- Information about whether your turnover will exceed the VAT registration threshold

- An indication of whether you intend to register voluntarily for VAT

- Expected profit levels, which SKAT may use to adjust your preliminary tax (forskudsopgørelse)

The key tax‑related documents to prepare and keep include:

- Your preliminary income assessment (forskudsopgørelse), which is updated when you start the business

- Any correspondence from SKAT confirming your VAT registration and VAT number (if applicable)

- Documentation on previous income if you are converting from employment or another business form; this helps you estimate future earnings more accurately

If you plan to employ staff, further documents are needed to register as an employer, including information on payroll administration, wage payments and holiday pay. For many very small sole proprietorships without employees, this extra layer is not relevant in the early stages, but should be considered if you intend to grow.

For foreign residents, SKAT may require additional documents such as foreign tax identification numbers and evidence of tax residency status in another country. These documents help avoid double taxation and ensure your income is correctly categorised within Danish tax law and any applicable tax treaties.

Bank Account and Financial Documentation

While Danish law does not always require a separate business bank account for a sole proprietorship, in practice it is strongly recommended and often expected by banks and accountants. To open a business account, Danish banks operate under strict anti‑money laundering (AML) and know‑your‑customer (KYC) rules, which means the document requirements can be extensive.

Typically, when you approach a bank to open an account for your sole proprietorship, you will need:

- A valid passport or national ID card to confirm your identity

- Your CPR number, and your CVR registration certificate or extract

- Proof of residential address, such as a recent utility bill or official letter

- A description of your business activities and anticipated transaction volumes

Banks may also ask for a simple business plan, client or supplier contracts, or prior financial data if you have run a business before. These are not always mandatory, but they greatly facilitate the assessment process and can expedite approval.

If you have recently moved to Denmark or are a non‑EU citizen, be prepared for additional documentation, such as residence and work permits, previous bank statements from your home country, and tax declarations. The bank's compliance team decides what is necessary to satisfy regulatory requirements, which means two different banks might request slightly different sets of documents.

Once the account is open, you should store all bank correspondence, account opening agreements, and terms and conditions. These documents form part of your business's financial core and are often needed when applying for credit facilities, leasing arrangements, or government programmes that support small businesses.

Industry‑Specific Licences, Permits and Registrations

Some types of business activity in Denmark are regulated and require specific licences or permits before you can legally operate. When you register your sole proprietorship, the basic business registration alone does not automatically grant you the right to carry out all kinds of activities. In regulated sectors, you must be ready to present additional documentation to the relevant authority.

Examples of activities that may require special permits include:

- Operating a restaurant, café or bar, which can involve food safety approvals, alcohol licences and municipal permissions

- Providing certain health or care services where professional authorisation or registration is required

- Handling specific hazardous substances or waste, which may involve environmental licences and technical documentation

Each permit or licence comes with its own application forms, supporting documents and renewal requirements. Usually you must provide evidence of qualifications, insurance coverage, safety procedures, or technical compliance. These supporting documents then become part of your overall business documentation set and should be stored alongside your general registration papers.

Before registering your business activity on Virk.dk, it is sensible to research whether your chosen branch code triggers any automatic notifications or additional documentation obligations. In some cases, the Danish Business Authority's system will guide you towards sector‑specific information, but you should still check municipal and national regulations independently, especially for food, health, childcare, construction and transport sectors.

Internal Record‑Keeping and Supporting Papers

Although not formally required during the moment of registration, robust internal documentation and record‑keeping are essential to operating a sole proprietorship responsibly in Denmark. Danish bookkeeping and tax rules expect you to retain all relevant financial and contractual documents for several years.

Key documents to maintain include:

- Invoices issued to clients and invoices received from suppliers

- Contracts or written agreements with major customers, subcontractors and landlords

- Receipts for all business‑related expenses, including small purchases

- Insurance policies, such as liability insurance or professional indemnity insurance

- Any written policies or internal guidelines relevant to regulated activities

In practice, this means establishing a clear digital or physical filing system from the day you register your business. Keeping these documents in order not only satisfies legal and tax obligations; it also makes it easier to demonstrate business viability to banks, investors, or public bodies if you later seek financing or support schemes.

Wrapping Up: Building a Complete Documentation Package

Opening a sole proprietorship in Denmark is a relatively accessible process, but it relies on a coherent documentation package that covers both your identity and your business. At the core are your CPR number, NemID/MitID, and the online registration form that creates your CVR number. Around this core you assemble tax registration documents, banking paperwork, proof of address and, where relevant, immigration and residence documents for foreign nationals.

On top of these general requirements come any industry‑specific licences or permits, which must be obtained before you commence regulated activities. Lastly, a disciplined approach to internal documentation - from invoices and receipts to contracts and insurance certificates - ensures that your business can withstand scrutiny from SKAT, banks and other authorities over time.

By collecting these documents systematically before and during registration, you give your Danish sole proprietorship a solid, compliant start and minimise administrative friction as your business grows.
