Denmark Business Tax Return Guide (Selskabsskat, SEL-angivelse)

Corporate Tax Rate (Selskabsskat)

Denmark applies a flat corporation tax rate of 22% on taxable profits for all limited companies. This is one of the lowest rates in the European Union and applies to both ApS (Anpartsselskab) and A/S (Aktieselskab) as well as other limited liability entities such as erhvervsdrivende fonde (foundations) and andelsforeninger (cooperatives) that are subject to corporate tax.

Key points about the corporate tax rate:

• Flat 22% rate — No progressive brackets for companies. All taxable income from all sources (trading, investments, capital gains) is taxed at 22%.
• Not applicable to sole proprietors — Enkeltmandsvirksomhed owners pay personal income tax (up to 52.07% in 2026 including AM-bidrag) on business profits, not corporate tax. Sole proprietors report business profit as B-income on their personal tax return.
• Effective tax rate considerations — While the headline rate is 22%, the effective rate can be lower after tax adjustments, depreciation, and loss carryforwards. Some income may be tax-exempt (e.g., certain dividends from subsidiaries under the participation exemption).
• Comparison with personal tax — The 22% corporate rate is significantly lower than the top marginal personal rate of 52.07%. However, distributed dividends are taxed again at the shareholder level (27% up to 61,000 DKK, 42% above), creating a combined rate if profits are distributed.

Filing Deadline

The standard deadline for filing the Danish corporate tax return (SEL-angivelse) is June 30 in the year following the income year. For the tax year 2025 (calendar year companies), the return is due June 30, 2026. For companies with a broken financial year, the deadline is 6 months after the end of the financial year.

Key deadline rules:

• Standard deadline — June 30 for calendar-year companies. Example: 2025 income year → due June 30, 2026.
• Extension possible — If you use a revisor (approved auditor) who is authorized by SKAT, the deadline can be extended to September 30 (or later in certain cases). The extension must be requested and the revisor must confirm their involvement.
• Penalty for late filing — A daily interest charge of approximately 7.7% per annum (2026 rate) accrues on any unpaid tax from the day after the deadline. Additionally, a late-filing fee of 700 DKK may apply.
• Estimated tax payments — Companies must pay estimated corporation tax in two instalments: March 20 and November 20 of the income year. Failure to pay sufficient estimated tax results in interest charges from the due dates.
• Final payment — Any remaining tax balance (after deducting estimated payments) is due on November 20 in the year following the income year. For tax year 2025, final payment is due November 20, 2026.

Missing the deadline triggers automatic interest and penalty assessments from SKAT. If you cannot meet the June 30 deadline, engage a revisor as early as possible to secure an extension. Note that estimated tax payments (påregnet skat) are due in two instalments during the income year: March 20 and November 20. If your estimated payments are too low, interest accrues from the instalment dates. Overpayments earn interest at a lower rate. Accurate estimation is a key part of tax planning, and many businesses use the previous year's tax as a baseline for current-year estimates.

Digital Filing (TastSelv Erhverv)

All corporate tax returns must be filed electronically through TastSelv Erhverv, SKAT's digital portal for businesses. Access requires MitID Erhverv, the mandatory digital signature system for Danish businesses. The process includes:

• SEL-angivelse form — The main corporate tax return form, which captures the income statement, balance sheet, tax adjustments, and calculation of taxable income. The form is pre-populated with certain data from the previous year and from SKAT's records.
• Annual report (årsrapport) — Must be attached to the tax return. The annual report includes: income statement (resultatopgørelse), balance sheet (balance), notes (noter), management review (ledelsesberetning), and auditor's report (revisionspåtegning) if applicable.
• Balance sheet and P&L — The balance sheet and profit and loss statement must be filed in a format compatible with SKAT's digital systems. Many accounting software packages (e.g., Dinero, e-conomics, Billy) can export directly to TastSelv Erhverv format.
• Auditor report — If your company exceeds the audit thresholds (balance sheet above 4 million DKK, revenue above 8 million DKK, or more than 12 employees on average), a revisor's (auditor's) report must be attached.

Errors in digital filing are common and can trigger SKAT reviews. We recommend having a revisor review the return before submission, especially in the first year. For detailed expense documentation, see the business expenses and deductions guide →.

Tax Return Contents

The Danish corporate tax return requires detailed financial information. The SEL-angivelse form has several sections that must be completed accurately:

• Income statement (resultatopgørelse) — Shows revenue, cost of goods sold, gross profit, operating expenses, depreciation, financial income and expenses, and net profit before tax. This should match the statutory annual report.
• Balance sheet (balance) — Assets (fixed and current), liabilities (short-term and long-term), and equity. The balance sheet total must tie to the annual report figures.
• Equity statement (egenkapitalopgørelse) — Movement in equity during the year: opening balance, profit/loss for the year, dividends paid, capital increases/reductions, and closing balance.
• Specification of added-back costs — Certain costs deducted in the financial statements must be added back for tax purposes, including non-deductible representation costs, fines, gifts, and depreciation differences.
• Tax adjustments (skattemæssige reguleringer) — Permanent and temporary differences between accounting profit and taxable profit. Common adjustments include: non-deductible expenses, tax-exempt income, timing differences from depreciation, and provisions.
• Depreciation and amortization schedules — Detailed schedules for tax depreciation (skattemæssige afskrivninger) on: buildings (bygninger), operating equipment (driftsmidler), goodwill, and intangible assets (patents, trademarks).
• Transfers to/from reserves — If using the Virksomhedsordning or other special schemes, specify transfers between reserves and taxable income.

All amounts must be reported in Danish kroner (DKK). If your accounting records are kept in a foreign currency, you must convert to DKK using SKAT's official exchange rates for the relevant period. For more on taxable income calculation, see our personal tax guide → if you are a sole proprietor. For reporting cryptocurrency income, capital gains, and digital asset transactions, see our Business Crypto Guide →.

Tax Adjustments

Danish tax law requires specific adjustments to accounting profit to arrive at taxable income. Understanding these adjustments is essential to avoid errors and penalties:

Non-deductible costs: Certain expenses are never deductible for tax purposes and must be added back to accounting profit:

• Fines and penalties — All fines, including traffic fines, SKAT penalties, and regulatory fines, are non-deductible.
• Gifts — Gifts to customers are deductible only up to limited amounts (approximately 100 DKK per recipient per year for promotional gifts). Gifts to employees are deductible up to specific tax-free limits; amounts above those are taxable for the employee and deductible for the company.
• Representation costs — Only 75% of restaurant and entertainment costs for business contacts are deductible. The remaining 25% is non-deductible and must be added back. Proper documentation (who, when, purpose, attendees) is essential.
• Private expenses — Any private expenses paid by the company (e.g., personal travel, family meals, private use of company assets) are not deductible.

Tax depreciation (skattemæssige afskrivninger): Assets must be depreciated according to tax rules, which may differ from accounting depreciation:

• Operating equipment (driftsmidler) — Declining balance method at up to 25% per year. Assets under 32,000 DKK (2026 threshold) can be expensed immediately under the småaktiver rule.
• Buildings (bygninger) — Straight-line depreciation over the useful life (typically 25-50 years depending on building type). No depreciation on residential portion.
• Goodwill — Declining balance at 1/7 per year (approximately 14.3%), meaning goodwill is written off over 7 years.
• Intangible assets — Patents, trademarks, and software licenses may be depreciated over their useful life, typically 5-10 years.

For detailed expense classification, refer to our business expenses and deductions guide →.

Loss Carryforward

Danish tax law allows companies to carry forward operating losses indefinitely. However, there are important limitations:

• Unlimited carryforward period — Tax losses can be carried forward with no time limit. There is no expiry for loss carryforwards under current Danish tax law.
• Annual utilization cap — Losses can offset up to approximately 8.5 million DKK per year (indexed annually). Above this threshold, only 60% of taxable income exceeding the cap can be offset by carried-forward losses. Example: if taxable income before loss offset is 18.5 million DKK, the first 8.5 million DKK can be fully offset, and only 60% of the remaining 10 million DKK (i.e., 6 million DKK) can be offset, leaving 4 million DKK currently taxable.
• No carryback — Denmark does not allow loss carryback. Losses cannot be applied to previous tax years. They can only be carried forward.
• Group relief (sambeskatning) — Companies in a Danish joint taxation group can transfer current-year losses between group members. The loss must be used in the current year and cannot be carried forward by the transferring company.
• Change of ownership limitations — If there is a change of ownership (more than 50% of shares or voting rights), loss carryforwards may be restricted or forfeited entirely. This rule prevents loss trafficking. Exceptions apply for reorganization, inheritance, or group restructurings meeting certain conditions.

Loss carryforwards must be tracked and documented carefully. SKAT may audit loss utilization, particularly after ownership changes. Maintain detailed records of the loss origins and subsequent utilization. For more on corporate tax obligations, see our starting a business guide → and company forms guide →.

Corporate Restructuring (Fusion, Spaltning, Tilførsel af Aktiver)

Danish tax law under the Fusionsskatteloven (FUL) allows qualifying corporate restructurings to be carried out tax-free (skattefrit), meaning no immediate taxation of gains on transferred assets. The most common forms are skattefri fusion (merger), skattefri spaltning (demerger), and skattefri tilførsel af aktiver (asset contribution). All require valid business reasons and must be filed with Erhvervsstyrelsen within prescribed deadlines.

Skattefri Fusion (Tax-Free Merger)

• No permission required from Skattestyrelsen since 2007 — self-assessment applies (FUL §§ 1-15).
• Conditions: The acquiring company issues shares to the target's shareholders as consideration (cash consideration ≤ 10% allowed).
• Succession: The acquiring company steps into the target's tax positions — including acquisition costs, depreciation balances, and loss carryforwards.
• Loss carryforwards transfer subject to limitation (FUL §8, stk. 7): ownership tests of 25%/50% apply.
• Merger date (fusionsdato) must align with a fiscal year boundary (FUL §5).
• Documentation must be filed within 1 month of adoption (FUL §6).

Skattefri Spaltning (Tax-Free Demerger)

• Governed by FUL §§ 15 a-15 b. Two types: with or without permission from Skattestyrelsen.
• Holding period (3 years): The receiving company must not dispose of shares received within 3 years. If an owner holding ≥10% sells within 3 years, the spaltning becomes taxable retroactively.
• Types: Continuation spaltning or partial demerger (grenspaltning).
• Loss carryforwards stay with the continuing entity — they cannot be split between resulting entities.

Skattefri Tilførsel af Aktiver (Tax-Free Asset Contribution)

• Governed by FUL §§ 15 c-15 d. One company contributes a whole business or branch (virksomhedsgren) to another in exchange for shares.
• Succession applies — the receiving company takes over the tax base values of the contributed assets.
• Consideration shares are valued at market value (handelsværdi) of contributed net assets.
• 3-year holding period applies to the consideration shares.

Key Conditions for All Tax-Free Restructurings

• Valid business purpose — tax avoidance motivation disqualifies the transaction.
• Share consideration primarily shares; cash limited to 10% (merger) or as permitted.
• 3-year holding period for shares received (unless subsequent qualifying restructuring).
• Continuity of business — the transferred activity must continue.
• Proper documentation filed with Erhvervsstyrelsen within deadlines.

VSO → ApS Conversion (Skattefri Virksomhedsomdannelse)

Sole proprietors using the Virksomhedsordning (VSO) can convert to an ApS tax-free under certain conditions via skattefri tilførsel af aktiver. Skatterådet has confirmed this treatment. The conversion allows you to transfer business assets to the new ApS at tax base values without triggering immediate taxation. The VSO's accumulated retained profits (opsparet overskud) are converted to share capital or contributed capital in the new ApS. For more on VSO, see our starting a business guide →.

Corporate restructuring is complex and carries significant tax risks if done incorrectly. Always engage a revisor and advokat (corporate lawyer) before proceeding. For company structure comparisons, see our company forms guide →. For holding company structuring and group joint taxation (sambeskatning), see our holding companies guide →.

FAQs

What is the deadline for filing the Danish corporate tax return?

The standard deadline is June 30 following the income year. For calendar-year companies, the 2025 tax return is due June 30, 2026. An extension to September 30 is possible with an authorized revisor.

Can I file the SEL-angivelse on paper?

No. All corporate tax returns must be filed digitally through TastSelv Erhverv using MitID Erhverv. Paper filing is not accepted except in exceptional circumstances approved by SKAT.

What happens if I miss the June 30 deadline?

SKAT imposes a daily interest charge of approximately 7.7% per annum on unpaid tax from July 1. A late-filing fee (700 DKK) also applies. Contact SKAT or your revisor immediately if you cannot meet the deadline.

How do I report tax depreciation in the return?

Tax depreciation is reported in the skattemæssige afskrivninger section of the SEL-angivelse. You must provide schedules for each asset category (operating equipment, buildings, goodwill, intangibles) showing cost, accumulated depreciation, and current year depreciation.

Are group companies required to file jointly?

Companies in a Danish joint taxation group must file a joint tax return (sambeskatningsangivelse) in addition to individual company returns. The group return shows the combined taxable income and loss transfers between group members.
