A Guide to Corporate Taxes in Denmark

Introduction to Corporate Tax in Denmark

Denmark applies a standard corporate income tax rate of 22%, as confirmed by the Danish Tax Agency, making compliance planning critical for financial efficiency. Companies must align with detailed reporting, filing, and payment obligations under the Danish corporate tax system.

The corporate tax system in Denmark requires accurate bookkeeping, timely filings, and adherence to digital reporting standards through the official TastSelv platform managed by the tax authority. Businesses must also comply with advance tax payments and annual tax return submissions, ensuring alignment with statutory deadlines. These requirements make structured corporate tax filing in Denmark a core operational priority.

Commenda supports global finance teams with end-to-end corporate tax compliance services, including entity management, filings, and reporting across jurisdictions. 

What Is the Corporate Tax Rate in Denmark?

The corporate tax rate in Denmark is 22% for most companies, including private limited (ApS) and public limited (A/S) entities. This standard corporate income tax rate in Denmark is confirmed by the Danish Tax Agency and applies to taxable profits.

The rate is generally uniform and does not vary based on company size, revenue, or ownership structure. However, specific sectors may face different regimes, such as oil and gas activities, which are taxed at 25% plus a 52% hydrocarbon tax, resulting in an effective rate of up to 64%.

• No reduced small-business rate; the same rate applies to all entities.
• Cooperative associations may be taxed at 14.3% under specific rules.

Withholding Taxes and Other Business Taxes in Denmark

• Value-Added Tax (VAT): Standard VAT rate: 25% on most goods and services

These taxes form a critical part of Denmark’s overall corporation tax, particularly for companies engaged in international transactions.

Corporate Tax Incentives, Deductions, and Exemptions

The Danish corporate tax system offers targeted incentives to support innovation, investment, and business growth, while aligning with EU and OECD standards.

Key incentives include:

• R&D Super Deduction
  • Companies can deduct up to 110%+ over time for qualifying R&D expenses.
  • Capital expenditure on R&D can be fully expensed immediately or depreciated over 5 years.
• Tax Credit for Loss-Making R&D Companies
  • Loss-making companies may receive a cash refund of 22% of qualifying R&D losses.
  • Capped at DKK 5.5 million (based on DKK 25 million in R&D expenditure).
  • Applies at the group level under joint taxation rules.

  • Costs related to the exploration of raw materials can be fully deducted in the same year.
• Participation Exemption
  • Dividends and capital gains from qualifying subsidiaries are generally tax-exempt (0%).

  • For specific assets, platforms, wells, and inter-platform installations, depreciation may be calculated at up to 15% on a declining-balance basis, while pipelines and other infrastructure assets may be depreciated at up to 7%.

These provisions enhance the attractiveness of operating under the corporate tax rate in Denmark, particularly for innovation-driven and multinational companies.
