The aarsopgorelse, your annual reckoning
What it is
The aarsopgorelse is your final tax settlement for the year - the reconciliation between what was withheld from your pay and what you actually owed. SKAT prepares it from data sent by employers, banks and pension funds, and publishes it in March. For most people it is already correct and finalises automatically.
The rhythm
- March: your pre-filled aarsopgorelse appears in TastSelv on skat.dk.
- Check it: confirm income, and add any deductions SKAT could not know about.
- Deadline: changes are usually due around 1 May (extendable to 1 July in some cases). Check skat.dk for the current year's date.
Refund or bill
If too much tax was withheld, you get a refund paid to your NemKonto. If too little, you owe the difference - pay by the deadline to avoid interest. The result flows directly from how accurate your forskudsopgorelse was during the year.
What to check
- Commuter deduction if your round trip exceeds 24 km - you must enter it.
- Union and A-kasse fees.
- Foreign income and accounts - tax residents must declare worldwide income.
- Any life changes (marriage, property, moving municipality) that affect your tax.
If your statement shows you owe money, see what to do if you underpaid tax.
