Your 2027 preliminary tax assessment: what to prepare

Prepare next year’s finances

The preliminary assessment is your budget for tax and income. The Danish Tax Agency normally opens next year’s assessment from mid-November. Written in September 2026, this guide prepares for 2027; it does not announce a confirmed opening date.

Start with known changes, such as a new job, retirement or relocation.

Information to have ready

Estimate income for all of 2027, including salary, pension and fees. Gather expected interest expenses, pension contributions and commuting days. Identify income, property and other matters abroad that need clarification.

Check the figures when the assessment opens

Compare prefilled information with your own budget and use the published 2027 rates. Ask the Danish Tax Agency if relevant fields are missing. Keep a list of uncertain estimates to revisit as contracts and plans are finalised.
