Tax Incentives for Research and Development in Denmark - 2026 Overview

Introduction to R&D Tax Incentives

Research and development (R&D) tax incentives in Denmark are designed to reduce the effective cost of innovation for companies and to make Denmark an attractive location for high‑value activities. The Danish rules allow qualifying R&D expenditure to be treated more favourably than ordinary operating costs, either by increasing the deductible amount in the corporate tax calculation or by providing a cash refund of tax losses linked to R&D.

For corporate income tax purposes, Denmark applies a standard corporate tax rate of 22%. R&D incentives work by allowing companies to deduct their qualifying R&D costs in the normal way and, in addition, to apply an uplift to those costs when calculating taxable income. Depending on the specific scheme and the company’s tax position, this can result in a lower tax bill or a cash payment from the tax authorities if the company is in a loss‑making position.

The incentives are available to Danish companies and Danish permanent establishments of foreign companies that carry out eligible R&D activities. In practice, this includes a wide range of sectors, from manufacturing, life sciences and clean tech to software, gaming and fintech, provided that the work aims at developing new or improved products, processes or services and involves a degree of technological or scientific uncertainty.

Unlike some jurisdictions, Denmark does not operate a separate, reduced “innovation tax rate” on R&D profits. Instead, the focus is on the treatment of R&D costs. Companies can typically:

These mechanisms are particularly important for start‑ups and scale‑ups that invest heavily in development but do not yet generate taxable profits. By converting part of their tax loss into a cash refund, the Danish system helps to improve liquidity and supports continuous investment in innovation.

To benefit from the incentives, companies must be able to document that their projects meet the Danish definition of R&D and that the related costs are directly connected to those activities. The Danish Tax Agency places emphasis on clear project descriptions, technical objectives and evidence that the work goes beyond routine improvements or standard commercial activities.

Overall, R&D tax incentives in Denmark form a central element of the country’s innovation policy. They complement other measures such as innovation grants and collaboration programmes with universities and research institutions. For businesses, understanding the basic structure of these incentives is the first step towards optimising their tax position and financing ongoing development projects.

Key Features of the R&D Tax Program

The Danish R&D tax incentive scheme is designed to support companies that invest in innovation, technology and product development. It is available to both Danish and foreign-owned businesses that are fully or partially tax liable in Denmark, regardless of size or industry, as long as they carry out qualifying research and development activities.

At its core, the scheme allows companies to obtain an immediate cash refund of part of their tax loss that arises from approved R&D costs. Instead of carrying the tax loss forward to future years, eligible businesses can convert a portion of that loss into a payable tax credit. This improves liquidity and reduces the financial risk associated with long-term development projects.

The key feature is the possibility to receive a cash refund equal to 22% of the tax value of R&D-related losses, up to a maximum R&D cost base of DKK 25 million per income year per company (or per jointly taxed group). In practice, this means that qualifying R&D expenses of up to DKK 25 million can generate a tax loss that may be converted into a credit, and the credit is paid out after the annual tax return has been assessed by the Danish Tax Agency.

The scheme is closely aligned with the general corporate tax rules. R&D costs are normally deductible as operating expenses, and the R&D tax credit is calculated on the part of the tax loss that can be attributed to these costs. If the company’s total R&D expenses exceed DKK 25 million, the excess still contributes to a tax loss that can be carried forward without time limitation, but only the portion up to the cap can be converted into a cash refund in the relevant year.

Another important characteristic is that the incentive is volume-based rather than incremental. Companies do not need to demonstrate an increase in R&D spending compared to previous years. Instead, all qualifying R&D costs within the income year can be included, provided they are properly documented and directly linked to eligible research or development projects.

The program is also neutral with respect to sector and technology. It covers a wide range of activities, from fundamental research and experimental development to applied research in areas such as software, engineering, life sciences, green technologies and advanced manufacturing. What matters is the presence of technological or scientific uncertainty and a systematic, project-based approach to resolving it.

From an administrative perspective, the R&D tax incentive is claimed through the standard corporate tax return, with a specific request for conversion of the R&D-related tax loss into a credit. Companies must be able to substantiate their claim with project descriptions, cost breakdowns and internal documentation that clearly separates R&D expenses from routine operational costs.

Finally, the Danish scheme is designed to be compatible with other forms of public support, such as innovation grants or EU funding, although double financing of the same cost item is not allowed. This makes the R&D tax program a central element in the broader Danish innovation ecosystem, providing predictable and rules-based tax relief that can be integrated into long-term R&D planning and budgeting.

Eligible R&D Activities and Costs

To benefit from Danish tax incentives for research and development, it is essential to understand which activities qualify as R&D and which costs can be included in the tax relief calculation. The Danish rules broadly follow the OECD Frascati principles, focusing on projects that seek to achieve scientific or technological advancement and involve a systematic approach to resolving uncertainty.

What qualifies as R&D activity in Denmark

In Denmark, R&D activities must be aimed at creating new knowledge, products, processes or services, or significantly improving existing ones. Typical eligible activities include:

Routine or cosmetic changes, such as minor updates to existing products, standard bug fixing, adaptation to a specific customer without technological uncertainty, or activities that are purely commercial or administrative, are not treated as R&D for tax purposes.

Eligible R&D costs

Denmark allows companies to deduct and, under specific conditions, obtain a cash refund for certain R&D-related costs. To qualify, expenses must be directly connected to eligible R&D projects and properly documented in the company’s accounts. Key categories include:

Costs and activities that are typically excluded

Not all innovation-related spending qualifies for R&D tax incentives. Commonly excluded items include:

Practical considerations for documenting eligibility

To make full use of Danish R&D tax incentives, companies should document their projects and costs in a structured way. This typically involves:

By aligning activities and costs with these criteria and maintaining robust documentation, companies operating in Denmark can maximise their access to R&D tax deductions and refunds while reducing the risk of adjustments during tax audits.

How to Apply for R&D Tax Relief

Applying for R&D tax relief in Denmark is closely linked to the ordinary corporate tax return process and to the rules on immediate expensing and cash refunds of R&D-related tax losses. The procedure is relatively straightforward, but it requires careful documentation and correct classification of costs to ensure that the Danish Tax Agency (Skattestyrelsen) accepts the claim.

1. Decide on the form of relief: deduction, uplift or cash refund

Companies can benefit from R&D incentives in Denmark in three main ways, which are all handled through the corporate tax return:

Before you start preparing your filing, clarify whether you expect a taxable profit (where deductions reduce tax payable) or a tax loss (where a cash refund of the tax value of R&D-related losses may be more attractive).

2. Map and document eligible R&D activities

The first practical step is to identify which projects qualify as research and development under Danish tax law. In broad terms, qualifying activities involve systematic work aimed at acquiring new knowledge or developing new or significantly improved products, services, processes or technologies, with a clear element of technological or scientific uncertainty.

For each project you intend to include in your claim, prepare internal documentation that typically covers:

This documentation does not have to follow a specific statutory format, but it should be detailed enough to demonstrate that the work goes beyond ordinary commercial development and meets the Danish definition of R&D.

3. Identify and allocate eligible costs

Once the projects are defined, you need to identify the costs that can be linked directly to those projects. Typical eligible cost categories include:

Costs must be allocated to projects on a reasonable and consistent basis. For salaries, this usually requires time registration or another reliable method of allocating working hours to specific R&D activities. For shared equipment or overheads, you should apply a documented allocation key that reflects actual use.

4. Prepare the corporate tax return (SEL § 8 B and refund rules)

R&D tax relief is claimed through the Danish corporate income tax return (selskabsselvangivelse). The key steps are:

  1. Ensure that R&D costs are correctly classified as deductible expenses under the Danish Corporation Tax Act provisions for research and development
  2. Include the total amount of eligible R&D costs in the relevant fields of the tax return, distinguishing between:
    • Costs deducted immediately in the income statement
    • Any additional deduction or uplift, if applicable
    • R&D-related losses that may form the basis for a cash refund
  3. Calculate the tax effect at the current corporate tax rate and determine whether a refund claim is possible based on your total tax position for the year

If you are part of a Danish tax consolidation group, the R&D costs and any resulting losses must be reported at group level, and the group’s administrative company is responsible for filing the consolidated return and any refund claim.

5. Claiming a cash refund of R&D-related tax losses

Denmark allows companies to request a cash refund of the tax value of certain losses that arise from R&D costs, up to a statutory annual cap per company or per jointly taxed group. The refund is calculated by multiplying the eligible loss by the corporate tax rate.

To apply for the refund, you must:

The Danish Tax Agency will process the refund after the tax return has been filed and may request additional information before paying out the amount.

6. Deadlines and electronic filing

Corporate tax returns, including R&D claims and refund requests, must be filed electronically via TastSelv Erhverv. The general filing deadline for companies is linked to the end of the income year and is set by the Danish tax rules for corporate returns. Late filing can lead to penalties and may delay or jeopardise the R&D tax relief.

Before the deadline, make sure that:

7. Supporting documentation and potential audits

Although you do not need to submit all documentation with the tax return, you must be able to present it promptly if Skattestyrelsen requests it. This typically includes:

The tax authorities may review whether the activities qualify as R&D and whether the cost allocation is reasonable. Well-structured documentation significantly reduces the risk of adjustments and helps secure the relief you are entitled to.

8. Using professional support

Many Danish companies choose to involve tax and accounting advisors to review their R&D portfolio, validate eligibility and optimise the claim within the current legal framework. Professional support can be particularly valuable if you are:

Regardless of whether you handle the process internally or with external assistance, a structured approach to identifying projects, documenting activities and allocating costs is essential to successfully applying for R&D tax relief in Denmark.

SkatteFUNN and Its Role in the Tax Relief Scheme

In Denmark, there is no dedicated R&D scheme called “SkatteFUNN” – this is a Norwegian program that is often mentioned in international discussions about research and development tax relief. In the Danish context, R&D support is provided through other instruments, primarily enhanced tax deductions for research and development costs and cash refunds of tax losses related to R&D. Because of the similarity in purpose, SkatteFUNN is frequently used as a reference point when comparing Danish rules with other Nordic regimes.

While SkatteFUNN in Norway is a state aid scheme that combines tax credits with a formal project approval process, Denmark relies on its own framework under the Danish Tax Assessment Act and related legislation. Danish companies can generally deduct 100% of their qualifying R&D expenses as operating costs and, in addition, obtain an extra deduction (uplift) for certain research and development activities. Loss-making companies may request a cash refund of the tax value of part of their R&D-related losses, subject to annual caps and specific conditions.

For international groups that know SkatteFUNN from Norway, it is important to understand that the Danish system:

In practice, the role that SkatteFUNN plays in Norway – encouraging companies to formalise R&D projects, document innovation activities and claim targeted tax relief – is fulfilled in Denmark by the combination of:

When planning cross-border R&D in the Nordic region, businesses should therefore treat SkatteFUNN as a Norwegian reference model and, for Denmark, focus on the specific Danish R&D tax deduction and refund rules, the documentation expected by the Danish Tax Agency, and the interaction with other Danish innovation incentives. Understanding these differences helps ensure that R&D projects are structured and documented in a way that maximises available Danish tax relief while remaining compliant with local regulations.

Tax Credits, Deductions, and Refunds

Denmark offers a combination of tax credits, enhanced deductions and cash refunds to encourage companies to invest in research and development. Understanding how these mechanisms work together is essential to optimise your overall tax position and secure the full benefit of the R&D scheme.

Enhanced deduction for R&D expenses

The core incentive is an enhanced tax deduction for qualifying R&D costs. Danish companies can deduct more than 100% of eligible R&D expenses when calculating taxable income, provided the activities meet the definition of research or development under Danish tax law. The enhanced deduction applies to both internal R&D and certain outsourced activities, as long as the company bears the financial risk and retains the rights to the results.

Qualifying costs typically include salaries and social security contributions for employees directly engaged in R&D, materials and consumables used in experimental work, depreciation of R&D equipment and software, and a proportionate share of overheads that can be clearly allocated to R&D projects. Non‑R&D costs, such as routine quality control, market research or general administration, are not eligible for the uplift and must be separated from genuine R&D expenditure.

Tax credits through loss utilisation

For profitable companies, the main benefit of the enhanced deduction is a lower corporate tax base and therefore a reduced corporate income tax liability at the standard Danish rate. For companies in a loss‑making position, the additional deduction increases tax losses that can be carried forward without time limitation and used to offset future taxable profits, effectively acting as a deferred tax credit.

Because the value of this tax credit depends on the company’s current and future tax position, it is important to model different scenarios before deciding how aggressively to claim the enhanced deduction. In some cases, it may be more advantageous to combine the deduction with a cash refund of R&D‑related losses, particularly for early‑stage or high‑growth businesses.

Cash refunds of R&D‑related tax losses

Danish rules allow certain companies to convert part of their R&D‑related tax losses into an immediate cash refund. This mechanism is especially relevant for start‑ups and innovative companies that invest heavily in R&D but do not yet generate sufficient taxable income to benefit from the deduction alone.

To qualify for a refund, the company must:

The refund is calculated as a percentage of the R&D‑related tax loss, up to a specified monetary cap per income year. Any remaining loss that is not refunded can still be carried forward and used to offset future profits. This structure allows companies to balance short‑term liquidity needs with long‑term tax planning.

Interaction between credits, deductions and refunds

In practice, Danish R&D tax incentives operate as a coordinated system rather than separate, isolated benefits. The enhanced deduction reduces taxable income, the resulting tax saving functions as a tax credit for profitable companies, and the refund mechanism provides liquidity for loss‑making businesses. Choosing the optimal combination depends on factors such as the company’s profitability, expected growth, group structure and the size and nature of R&D projects.

Because the same R&D costs cannot be used multiple times for different incentives, careful tracking and allocation of expenses is essential. Companies should maintain clear project‑based records, reconcile R&D costs with the general ledger and ensure that only eligible expenditure is included in the tax calculation. This not only maximises the benefit of the incentives but also reduces the risk of disputes with the Danish tax authorities.

Strategic considerations for Danish R&D tax planning

Effective use of Danish R&D tax incentives requires more than simply identifying qualifying costs at year‑end. Many companies benefit from integrating tax considerations into their R&D budgeting and project management processes. This can include aligning internal cost centres with tax categories, documenting the scientific or technological uncertainties addressed by each project, and assessing whether to claim a refund or carry losses forward based on cash‑flow forecasts.

By understanding how tax credits, enhanced deductions and refunds interact under Danish law, businesses can significantly reduce the net cost of innovation, improve liquidity and strengthen their competitive position while remaining fully compliant with current tax regulations.

Deadlines and Filing Requirements

Correct timing and accurate filing are essential to benefit from Danish R&D tax incentives. Missing a deadline or submitting incomplete documentation can result in losing the right to an uplift deduction or a cash refund, even if the underlying R&D activities are fully eligible.

Corporate tax return deadlines

Companies claiming R&D tax incentives must do so through the annual corporate tax return (Form Selvangivelse for selskaber). The standard filing deadline is:

The R&D uplift deduction and any request for a cash refund of tax losses must be included in the return submitted by this deadline. Late filing can lead to loss of the uplift and delay or denial of refunds.

Deadline for requesting the R&D uplift and cash refund

Denmark allows an additional deduction (uplift) on qualifying R&D costs and a cash refund of tax losses up to a specified ceiling. To benefit:

There is no separate later deadline for the uplift or refund claim: if the R&D incentive is not included in the original or corrected return filed within the statutory time limits, the right to claim may be lost.

Amended returns and correction window

If errors are discovered after filing, companies can usually submit an amended return within the general reassessment period. As a rule, the Danish Tax Agency may reassess corporate tax up to 3 years after the end of the relevant income year. Within this period, it is often possible to correct or supplement an R&D claim, provided that:

However, relying on later corrections is risky. The tax authorities may reject late or insufficiently documented claims, especially where the original return did not mention R&D incentives at all.

Documentation and record‑keeping requirements

To support an R&D tax incentive claim, companies must maintain detailed records that can be presented to the Danish Tax Agency on request. At a minimum, this should include:

These records should be kept for at least the duration of the tax reassessment period, and in practice many companies retain them longer to support ongoing or related projects.

Interaction with advance tax and instalments

R&D incentives can affect the company’s effective tax burden and therefore its advance tax payments. When planning instalments, companies should:

Although adjustments to instalments can be made during the year, the final R&D claim must still be aligned with the figures reported in the annual corporate tax return.

Practical steps to stay compliant

To meet deadlines and filing requirements efficiently, many Danish companies integrate R&D tax planning into their year‑end closing process. Recommended practices include:

By aligning internal processes with statutory deadlines and documentation standards, companies can secure the full benefit of Danish R&D tax incentives while reducing the risk of disputes with the tax authorities.

Benefits of R&D Tax Incentives for Innovation

R&D tax incentives in Denmark are designed to reduce the effective cost of innovation and make it more attractive for companies to develop new or improved products, services and processes. By allowing enhanced deductions for qualifying R&D costs and offering a cash refund option for tax losses, the Danish regime directly supports both liquidity and long‑term competitiveness.

One of the most important benefits is the possibility to deduct qualifying R&D expenses at a rate higher than 100% when calculating taxable income. Companies can currently claim a super deduction of 108% of eligible R&D costs, meaning that for every DKK 1,000 spent on qualifying R&D, DKK 1,080 can be deducted from the taxable base. This reduces the effective corporate tax burden on innovative activities and makes it easier to justify long‑term development projects in internal budgeting.

Another key advantage is the opportunity to convert tax losses generated by R&D activities into a cash refund. Danish companies that report a tax loss after applying the R&D super deduction can request a refund of the tax value of the loss, up to a capped amount of R&D costs per year. This mechanism is particularly valuable for start‑ups and scale‑ups that invest heavily in development but do not yet generate sufficient taxable profits. Instead of waiting several years to use tax losses, they can strengthen their cash flow in the short term and reinvest the funds into further research, hiring or market expansion.

R&D tax incentives also help Danish businesses manage risk. Innovation projects often involve uncertain outcomes and long payback periods. By lowering the net cost of each project through enhanced deductions and potential refunds, the tax system effectively shares part of the financial risk with the company. This can encourage management teams to approve more ambitious projects, explore new technologies and enter new markets, while still maintaining a responsible approach to cost control.

From a strategic perspective, the Danish R&D tax regime supports the development of high‑value activities within the country. Companies that take full advantage of the incentives are more likely to locate their development teams, laboratories and pilot production lines in Denmark, rather than moving them abroad. This can lead to stronger in‑house know‑how, closer collaboration between R&D and operations, and better protection of intellectual property. Over time, these factors contribute to higher productivity, stronger brands and a more resilient competitive position on international markets.

The incentives also create a more favourable environment for collaboration with universities, research institutes and technology partners. Because a broad range of R&D costs can be included in the tax calculation, companies can structure joint projects, contract research and technology trials in a way that remains tax‑efficient. This supports knowledge transfer, accelerates the commercialisation of scientific results and helps businesses access specialised expertise that would be difficult or costly to build internally.

For many companies, an additional benefit lies in the discipline that comes with documenting R&D activities for tax purposes. To qualify for the incentives, businesses must describe their projects, objectives, uncertainties and technical challenges, and keep clear records of related costs. This documentation can also be used for internal project management, funding applications and intellectual property strategies. As a result, the tax incentive framework indirectly promotes better governance of innovation portfolios and more informed decision‑making.

Finally, R&D tax incentives in Denmark play a role in attracting foreign investment. International groups comparing locations for new development centres often look at the overall tax environment, including the treatment of R&D. A predictable regime with clear rules on eligible activities, enhanced deductions and refund options can make Denmark more attractive as a hub for regional or global innovation. For Danish subsidiaries, this can translate into larger R&D budgets, more advanced projects and increased responsibility within the group.

When used strategically and in full compliance with the rules, Danish R&D tax incentives can therefore deliver benefits that go far beyond immediate tax savings. They support liquidity, reduce risk, encourage collaboration and help build a long‑term culture of innovation that strengthens both individual companies and the wider Danish economy.

Common Mistakes and How to Avoid Them

Many companies in Denmark miss out on a significant part of the available R&D tax relief simply because of avoidable errors in documentation, classification and timing. Below are the most frequent mistakes businesses make when claiming Danish R&D tax incentives, together with practical ways to avoid them.

1. Treating Routine Work as R&D

A common mistake is to classify ordinary product updates, bug fixing or routine quality control as research and development. The Danish rules require that R&D activities aim at achieving new scientific or technological knowledge or solving technological uncertainties, not just maintaining existing products or processes.

To avoid this, clearly distinguish between:

Document the uncertainties you faced, the hypotheses you tested and the experiments or prototypes you developed. This makes it easier to demonstrate that the work qualifies as R&D under Danish tax law.

2. Incomplete or Weak Documentation

Another frequent error is relying on high-level descriptions or informal notes instead of structured documentation. The Danish Tax Agency expects you to be able to show how your projects meet the R&D criteria and how the related costs have been calculated.

Good practice includes:

Consistent documentation not only supports your claim but also reduces the risk of adjustments during a tax audit.

3. Misallocating Staff Costs

Wage and salary costs are often the largest component of an R&D claim, and they are also a common source of mistakes. Businesses sometimes include 100% of an employee’s salary even when the person spends only part of their time on eligible R&D activities, or they fail to include eligible staff such as project managers and supporting technical staff.

To avoid misallocations:

4. Overlooking Eligible Indirect Costs

Some companies focus only on direct project costs and forget that certain indirect costs can also be linked to R&D when they are clearly attributable to the projects. This can lead to underclaiming the available tax relief.

Review whether you can reasonably allocate, for example:

Make sure that your allocation method is consistent, documented and based on objective criteria such as usage hours or project budgets.

5. Missing or Misunderstanding Deadlines

R&D tax incentives in Denmark are tied to the corporate tax return and specific filing deadlines. A frequent mistake is assuming that claims can be adjusted at any time or that late documentation will always be accepted.

To stay compliant:

Missing a deadline can limit your ability to claim or adjust R&D tax relief for that year.

6. Ignoring the Impact of Loss Positions and Refund Options

Companies that operate at a loss sometimes assume that R&D tax incentives are not relevant to them. Under Danish rules, however, certain R&D-related tax benefits may be available even when the company is not yet profitable.

Common pitfalls include:

Regularly review your tax position and R&D pipeline so that you can plan the timing of projects and claims in a way that maximises the benefit.

7. Treating All External Work as R&D

Another mistake is to assume that any invoice from a technology or consulting provider automatically qualifies as R&D expenditure. Only work that directly contributes to your eligible R&D projects can be included, and the nature of the work must meet the same criteria that apply to in-house activities.

To avoid this error:

8. Poor Coordination Between Finance and Technical Teams

In many organisations, the finance department prepares the tax return while engineers and developers manage the R&D projects. If these teams do not coordinate, important projects and costs may be missed, or non-qualifying work may be included by mistake.

Improve coordination by:

9. Not Preparing for a Possible Tax Audit

Some companies only think about documentation when they receive questions from the Danish Tax Agency. This reactive approach increases the risk of adjustments, additional tax and interest.

To be audit-ready:

Being prepared makes the audit process smoother and reduces the time and resources needed to respond.

10. Failing to Review the Rules Regularly

R&D tax rules and administrative practices in Denmark can change over time. A common mistake is to rely on outdated assumptions or to copy last year’s approach without checking whether the legal framework or guidance has been updated.

To avoid this, review official guidance from the Danish Tax Agency on a regular basis and update your internal policies and project templates when needed. If your business model or R&D strategy changes, reassess how this affects your eligibility and the way you calculate and document R&D costs.

By addressing these common mistakes proactively, companies operating in Denmark can strengthen their compliance, reduce the risk of disputes with the tax authorities and make full use of the R&D tax incentives available to support innovation and long-term growth.
