On 27 October 2026, the Danish Tax Agency announced that the preliminary income assessment (forskudsopgørelse) for the 2027 tax year will open on 24 November 2026. Approximately 5.5 million taxpayers will gain access to their draft assessments via the TastSelv digital platform. The preliminary assessment projects monthly tax withholdings based on expected income and deductions. Taxpayers are urged to review and update their information — including expected earnings, commuting deductions, pension contributions, and other allowances — to ensure accurate monthly tax deductions throughout 2027. Failure to adjust the assessment may result in under‑ or over‑payment of taxes, leading to year‑end balancing payments or refunds with interest. The Agency provides guidance tools and assistance for complex situations, such as multiple income sources or foreign income.
Key Takeaways
- Early Access Window: Taxpayers have from 24 November 2026 to adjust their 2027 preliminary assessment before the tax year begins.
- Digital Self‑Service: Updates are made through TastSelv, the Tax Agency’s online portal, with real‑time recalculation of monthly withholdings.
- Proactive Compliance: Accurate preliminary assessments reduce year‑end settlements, interest charges, and administrative burden for both taxpayers and the Agency.
