A Skatteverket decision letter always states a deadline for disputing it, but the deadline is not the same on every letter. Some decisions give six years to act. Others give two months. Confusing the two tracks is the easiest way to lose the right to challenge a decision at all.
This guide sets out both deadline tracks, the difference between omprövning (Skatteverket's own reconsideration) and överklagande (the appeal to court), what happens to the disputed tax while the case is under review, and the appeal path available beyond Skatteverket itself. For other Sweden Unpacked guides on appeals and disputes, start with the topic overview.

Read the Decision for the Deadline That Applies to It
Most decisions on your annual income tax can be reconsidered or appealed within six years of the end of the income year, according to Skatteverket's guidance on changing, reconsidering, or appealing a tax return. In 2026, that six-year window still reaches back to income year 2020. Some other Skatteverket decisions carry a two-month deadline instead, stated directly on the decision itself.
If the decision is an annual income-tax assessment, the six-year deadline applies; if it is one of the shorter-deadline decision types, two months applies instead. The two-month clock starts on the day you receive the decision, not the day Skatteverket issues it. Check the deadline printed on your own letter before assuming either track applies to you.
| Track | Deadline | Counted from |
|---|
| Annual income-tax decision (omprövning or överklagande) | Six years | End of the relevant income year |
| Other Skatteverket decision types | Two months | Day the decision was received |
| Appeal to kammarrätten (tax cases) | Two months | Day the förvaltningsrätten decision was received |
| Appeal in most other administrative matters | Three weeks | Day the decision was received |

Omprövning and Överklagande Are Not the Same Request
Omprövning asks Skatteverket to reconsider its own decision. Överklagande asks the administrative court to review the decision instead, though the request is still sent to Skatteverket first.
You can request omprövning even when you already agree with most of the decision and only want one correction added. Överklagande fits a different situation: you want the court, not Skatteverket, to make the final call. Both requests start on the same form and go to the same address, so choosing the wrong label rarely blocks the case, but naming the right one speeds up how Skatteverket handles it.
Write the Request: What It Must State
The request must identify which decision you are disputing, explain why you believe it is wrong, state how you want it changed, and include your contact details, according to Skatteverket's English-language review-and-appeal guidance.
Attach the evidence that supports the correction: receipts, contracts, or other documentation relevant to the disputed item. Send a written request to Skatteverket, 205 30 Malmö, or use the online form if the case is already in progress. Keep a copy of everything submitted, since the request forms the basis for both the internal reconsideration and any later court review.
Skatteverket Reviews the Case Again Before Any Court Sees It
When Skatteverket receives an överklagande, it examines the case again before any court becomes involved. This internal re-examination is a genuine second look, not a formality on the way to court.
If Skatteverket agrees with you, it issues a new decision instead of forwarding the case to förvaltningsrätten. If it disagrees, or agrees only in part, it sends your original request and its new decision to förvaltningsrätten together. Either way, you receive the outcome in writing before the case moves any further.
Unique insight: Most descriptions of a Skatteverket dispute treat it as a single filing step to a court. The actual route has three successive filters, not one appeal: Skatteverket's own re-examination on receiving an överklagande, then a separate leave-to-appeal gate at kammarrätten, then a second leave-to-appeal gate at Högsta förvaltningsdomstolen. A case only reaches a judge for a full hearing at the first of those three filters, förvaltningsrätten; the two stages above it decide only whether the case is heard at all.
The Disputed Tax Is Still Due While the Case Is Under Review
Filing a request for omprövning or överklagande does not pause the payment due under the original decision. The tax and any interest charges stated in the decision remain due on the original schedule while Skatteverket, and later the court, reviews the case.
Anstånd is available only in exceptional, documented circumstances, not simply because a case is open. If Skatteverket grants anstånd, the payment deadline moves; if it does not, the original due date stands regardless of how the review is progressing. Assume the payment obligation continues unless anstånd has been confirmed in writing.
What Förvaltningsrätten Reviews, and How You Find Out the Result
Förvaltningsrätten reviews the case Skatteverket forwards to it and notifies you by letter once a decision has been made, according to Sveriges Domstolar's guidance on appealing a tax decision. There is no fee to have a tax appeal decided at this stage.
Förvaltningsrätten is the first court instance in a tax dispute, separate from Skatteverket's own internal reconsideration. The letter is how you learn the outcome; expect no phone call and no automatic update to your Skatteverket account. Read the letter carefully, since it also states whether further appeal is possible.
Appealing Further Needs Prövningstillstånd, at Two More Stages
A förvaltningsrätten decision can be appealed to kammarrätten, and a kammarrätten decision can be appealed to Högsta förvaltningsdomstolen, but both stages require prövningstillstånd, according to Sveriges Domstolar's guidance on appealing to kammarrätten. Leave to appeal is granted only if the case sets a precedent or an exceptional reason applies, not simply because you disagree with the earlier ruling.
Tax cases generally carry a two-month deadline to appeal to kammarrätten, longer than the three-week deadline used in most other administrative matters. If prövningstillstånd is refused at either stage, the refusal cannot itself be appealed, and the lower court's decision stands as final, per Sveriges Domstolar's guidance on appealing to Högsta förvaltningsdomstolen.
For comparison, how a citizenship decision is appealed, on a much shorter deadline follows a different clock entirely, which is why checking the specific deadline on each decision type matters.
Frequently Asked Questions
How long do you have to appeal a Skatteverket decision?
Most income-tax decisions carry a six-year deadline from the end of the income year. Some other decision types carry a two-month deadline instead, counted from the day you receive the decision and stated on the decision itself, per Skatteverket.
What is the difference between omprövning and överklagande?
Omprövning asks Skatteverket to reconsider its own decision. Överklagande asks the administrative court to review the decision, though the request is still sent to Skatteverket first, per Skatteverket.
Do you have to pay disputed tax while the case is under review?
Yes. The original payment schedule continues unless Skatteverket grants anstånd for documented exceptional circumstances, per Skatteverket.
Can a kammarrätten decision be appealed further?
Yes, to Högsta förvaltningsdomstolen, but only with prövningstillstånd, granted for precedent value or an exceptional reason. If leave is refused, kammarrätten's decision stands, per Sveriges Domstolar.
Conclusion
The single action that protects your case is reading the deadline printed on your own decision letter before assuming either track applies to you. The two-month track overrides the six-year default for specific decision types, and missing it closes the door regardless of how strong the underlying case is, since no filter further along the process, Skatteverket's re-examination, förvaltningsrätten, kammarrätten, or Högsta förvaltningsdomstolen, can revive a request submitted too late.
