If you are right, money comes back

The municipality lowers the value and refunds the tax you overpaid. You keep the full saving; no share goes to an agency.

Paying less tax does not mean a lower selling price

The WOZ value is the municipality’s calculation figure, not an asking price.

More detail

The WOZ value is a municipal calculation, not an asking price. What a buyer pays is set by the market: condition, location and recent sales nearby.

A WOZ value that is too high costs you money again every year, for as long as it stands. A sale happens once, and usually years away.

Why this exists

Municipalities appraise thousands of homes at once with a model. That goes wrong regularly.

More detail

Municipalities value thousands of homes at once with a model. It goes wrong regularly: a wrong floor area, an extension that is not there, a comparison with a sale at the top of the market.

Since the fees were cut in 2024, the no-cure-no-pay agencies have largely gone. Woonbelasting gives you the same public data, free.

Frequently asked questions

See all questions
What does Woonbelasting cost?
Nothing. There is no account, no subscription and no paywall. The source code is public so you can verify that it stays that way.
How long do I have to object?
Six weeks from the dagtekening on your WOZ decision: the date printed on the letter from your municipality. Woonbelasting works out your end date as soon as you enter it.
Is objecting to the WOZ free?
Yes. An objection to your municipality costs nothing, even if you lose. Only an appeal to the district court carries a court fee.
Where do the figures come from?
Your address comes from the national address and buildings register (BAG) via the PDOK location server. The valuations come from the national WOZ register. Both are public government sources; Woonbelasting adds no estimates of its own.
Why is there no floor area for my home?
Not every municipality publishes the floor area in the WOZ register. You can enter it yourself; it is on your valuation report or in your deed of purchase. And if the area the municipality uses is wrong, that alone is a strong ground for objection.
Do you store my data?
No. Your name, address and any BSN stay in your browser and only reach the server at the moment the PDF is built. The PDF is assembled in memory, sent straight to you and stored nowhere. There are no trackers, no third-party cookies and no advertising.
