If you own property in Denmark, the public property assessment (ejendomsvurdering) does not arrive as one letter — it is a SERIES: first a data letter, then the assessment itself, and for older assessment years a separate letter opening your right to appeal. Each letter has its own deadline, they all arrive in Danish, and the official English pages stop short of the deadlines. Here is the table that tells you which letter you are holding — and what to check.
Find your letter in the table
| Letter type | What you check | Where the deadline is |
|---|---|---|
| Deklaration — arrives BEFORE the assessment and shows the data that will be used | Is the data about your property correct and complete? BBR errors: update bbr.dk, then flag it in an objection | In the letter — the objection window is 4 weeks, and objecting is free |
| The assessment (vurderingsmeddelelse — 2022 assessment / 2021 reassessment) | The numbers behind the property and land value — and whether an appeal could move the value by more than 20 per cent | In the letter — the Tax Appeals Agency must receive the appeal within 3 months of receipt |
| Letter opening your appeal window (2020 and the historical 2013-19 assessments) | That the letter concerns your property — and which assessment year it opens the appeal for | In that letter — before it arrives, there is no appeal step to take |
| Preliminary assessment (foreløbig vurdering — used for property tax 2024-2026) | Orientation only — and note: the 2024 assessment cannot be appealed; it builds on the 2022 assessment | No appeal deadline to watch — a successful 2022 appeal is carried forward automatically |
Objection and appeal are two different tracks
- Objection (indsigelse) belongs to the deklaration: if you have found wrong or missing information, you file an objection within 4 weeks — free of charge. The process runs through vurderingsportalen.dk (Danish; the portal's English section explains the assessment system itself).
- Appeal (klage) belongs to the assessment: the Tax Appeals Agency must have received your appeal no later than 3 months after the day you received the assessment — and the appeal must be capable of changing the property or land value by more than 20 per cent, otherwise the appeals authority cannot change the assessment. There is an appeal fee (the amount is stated in the appeal guidance in your letter), and you can ask for reassessment (genoptagelse) instead.
- Neither track goes through your kommune. Municipal decisions — benefits, day-care, social support — have a completely different complaint route; that one is covered in our Danish guide to appealing kommune decisions.
The assessment feeds directly into your property tax: when the assessment arrives, your property tax is recalculated and settled. The yearly rhythm of the big letters — including the tax assessment notice (årsopgørelse) — is mapped in the Danish letter calendar.
What you check, whichever letter it is
1. Which letter is it? (deklaration, assessment, appeal-window letter — or a preliminary assessment)
2. Which property and which assessment year does it concern?
3. Is there a deadline — and from which day does it run?
4. What exactly does the letter ask you to do — and through which channel?
5. Keep the letter: later letters in the series refer back to it.
Where this page stops
This page helps you tell the letter types and deadlines apart. Whether your assessment is CORRECT — the numbers, the method, your property's particulars — it does not judge; that track belongs to vurderingsportalen.dk and the appeal guidance in your own letter. Sofia helps you decode which letter you are holding and what it asks of you — in plain English.

Explain my letterFrequently asked questions
What is the deklaration?
A letter you receive BEFORE the assessment itself. It lists the data the Danish Tax Administration intends to use to assess your property. If you find errors or missing information, you can file an objection (indsigelse) — you have 4 weeks, and it is free. If the error concerns BBR data (the building register), bbr.dk must be updated first, after which you flag it in an objection.
Who do I appeal to about the assessment itself?
The Tax Appeals Agency (Skatteankestyrelsen). For the 2022 assessment and the 2021 reassessment, the agency must have RECEIVED your appeal no later than 3 months after the day you received the assessment. Your appeal must also be capable of changing the property or land value by more than 20 per cent — otherwise the appeals authority cannot change the assessment. The exact deadline and procedure are stated in your own letter.
Can I appeal my 2024 assessment?
No — the 2024 assessment cannot be appealed, because it is based on the 2022 assessment, adjusted for house-price developments. If your appeal against the 2022 assessment succeeds, the changes are carried forward to your 2024 assessment.
Why can I not appeal my 2020 assessment or the historical assessments yet?
Because the right to appeal opens in stages: you can only appeal the 2020 assessment — and the historical 2013-19 assessments — once you have received a letter telling you that your appeal window is now open. Until that letter arrives, there is no appeal step to take.
