Danish Tax Deductions to Claim

The one-line versionSome deductions are automatic; others you must claim yourself on your tax return. The commonly-missed ones are commuting, union/A-kasse fees, and home-service work - all entered by you.

Automatic vs claim-it-yourself

Denmark pre-fills most of your tax, but not everything. The employment deduction is automatic - the ones people leave on the table are those you have to enter on your forskudsopgørelse or årsopgørelse.

The big automatic one

Employment deduction (beskæftigelsesfradrag): 12.75% of your employment income, capped at DKK 63,300 in 2026 (up from DKK 55,600 in 2025). It's applied automatically to everyone who works - you don't claim it, but it's worth knowing it's there.

The ones you must claim

Deduction	2026 detail
Commuter deduction (befordringsfradrag)	For round trips over 24 km; a set rate per km. You enter it.
Union & A-kasse fees	Union fees deductible up to DKK 7,000/yr; A-kasse (unemployment insurance) also deductible.
Pension contributions	Private contributions reduce personal income - and can pull you under a tax bracket.
Home services (servicefradrag/BoligJob)	Certain domestic and handyman work, up to an annual cap.
Interest on loans	Mortgage and loan interest reduces capital income (mostly pre-filled, but check).

Commuting adds up fastIf your daily round trip exceeds 24 km, the commuter deduction can be worth thousands of kroner a year - but SKAT doesn't know your route, so you must enter it yourself. Long-distance commuters lose the most by forgetting.

When to enter them

Two moments matter. Update your forskudsopgørelse (preliminary assessment) during the year so your monthly tax already reflects the deduction - you feel it in every payslip. And check your årsopgørelse in spring to catch anything missed - you can still add deductions and get money back.

Pension is the quiet win for higher earnersBeyond the direct deduction, pension contributions lower your personal income, which can drop you below the middle- or top-tax threshold. For earners just over a bracket line, it's often the most efficient move available.

SKAT won't add these for youThe commuter deduction, union fees and home-service work aren't pre-filled - if you don't enter them, you simply overpay. A few minutes on your assessment is genuinely worth real money.

Common questions

Which deductions are automatic?

The employment deduction and most interest on Danish loans are pre-filled. Commuting, union/A-kasse fees and home services are not - you enter them.

Can I backdate a missed deduction?

You can usually correct your årsopgørelse for prior years within SKAT's time limits - check TastSelv. It's often worth doing.

Does the commuter deduction apply if I bike or cycle?

It's based on distance over 24 km round trip regardless of transport mode - you claim the set per-km rate. Check skat.dk for the current rate and bands.
