UDK 450 Housing Benefit: Declare Your Wealth (Formue)

What is UDK 450 — Housing benefit: declare wealth (formue)?

Danish housing benefit (boligstøtte) depends partly on the wealth (formue) of everyone who lives in the home. The form's own guidance gives the 2026 limits: combined wealth above 896.400 kr. counts in the calculation, or above 1.060.300 kr. if you or someone else in the home is a state pensioner or an early-retirement pensioner from before 2003. Udbetaling Danmark therefore checks the figures, and each January it writes to recipients under the heading 'Bekræft formuen for at boligstøtten fortsætter' (confirm your wealth so your housing benefit continues).

UDK 450 is the paper answer. If the figures in the letter are right, you tick 'Jeg bekræfter formuen' and sign. If not, pages 2 and 3 have a grid with one column per person, up to four people, identified by CPR number. Section A covers property value, bank deposits, bonds, mortgage deeds, shares and debt. B covers loans from the municipality or Udbetaling Danmark, and C compensation and the value of a cooperative flat. D, other wealth such as cash, cars, boats, business equity and assets abroad, is only needed when the household's combined wealth is above 100.000 kr.

FileIt shows the grid one person at a time, in English with the Danish line names, and prints the amounts right-aligned in the kroner boxes of Udbetaling Danmark's own PDF. Names and remarks keep letters such as ø, ł or ș. You print the form, then you and every other adult in the home sign page 1 by hand before you post it.

How to fill out UDK 450 — Housing benefit: declare wealth (formue), step by step

1 Dine oplysninger (your details)

The recipient's name, CPR number, address and phone number.

2 Jeg bekræfter formuen (I confirm the wealth)

Tick this if the figures in the January letter are correct. Then you don't fill in pages 2-3, but you still sign.

3 A. Formue (wealth)

For each person: property value, money in banks, bonds and investment fund certificates, mortgage deeds in a deposit, shares, and remaining debt on loans. Whole kroner, with Danish dots if you like (125.000).

4 B. Lån ydet af kommunen eller Udbetaling Danmark (public loans)

Debt on a housing benefit loan (boligstøttelån) and on a property tax loan (ejendomsskattelån).

5 C. Egne oplysninger (your own information)

Compensation, damages or restricted wealth, and the value of a cooperative flat as approved at the last general meeting.

6 D. Anden formue (other wealth)

Only if everyone's wealth together is more than 100.000 kr.: cash, cars, private receivables, other securities, boats, business equity, property abroad, deposits abroad and other debt. Room for remarks at the bottom of page 3.

Everyone signing declares on their honour that the information is correct and consents to Udbetaling Danmark obtaining and passing on relevant information. The recipient dates and signs the first box, and other adults in the home sign the three boxes below.

Common mistakes to avoid

Using the provisional property value (foreløbig ejendomsværdi) from Skattestyrelsen. The form asks for the latest final value.
Leaving out someone who lives in the home. The form asks about everyone, children included.
Forgetting the other adults' signatures. Everyone over 18 in the home must sign page 1.
Filling in section D when the household's combined wealth is 100.000 kr. or less. It isn't needed then.
Guessing the cooperative flat's value instead of using the share value approved at the last general meeting.

Yes. FileIt lets you fill it in online, one person at a time, in English with the Danish line names, and prints the figures into the official PDF. You still print, sign and post it.

How much wealth can you have and still get boligstøtte?

The form says wealth counts in the calculation once the household's combined wealth is more than 896.400 kr. (2026), or 1.060.300 kr. if someone in the home is a state pensioner or a pre-2003 early-retirement pensioner. It doesn't say that benefit stops at those amounts.

Not if you tick 'Jeg bekræfter formuen' because the figures in the January letter are correct. Otherwise, give each person's current wealth.
