How it works

A minute-and-a-half walkthrough. Free, no account and no cookies. The letter is not stored on the server; you send it yourself.

Video transcript

Here's how to check your W-O-Z value, with Woonbelasting.

Step one. Enter your postcode and house number. That's all it needs.

Then tap: Work out my saving.

Step two. You see the assessed W-O-Z value, the floor area, and how the value has changed.

It compares your home with similar homes nearby. Here, there wasn't enough data for a verdict, and it says so honestly.

You can still create an objection letter.

Step three. Add your name. Your address is already filled in.

Use your municipality's postal address,

and add the number and date of your W-O-Z decision. You'll see how many days you have left.

Step four. Choose why the value is too high, and add a short explanation.

Step five. Review your letter. It's in Dutch, and you can still edit everything.

A short pro-forma objection keeps your deadline safe while you gather evidence.

Then download the PDF, sign it, and send it yourself.

It's free, with no account and no cookies. And your letter isn't stored on the server.

That's it! Try it at woonbelastingcheck dot N L.

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.

How it works

Frequently asked questions

See all questions
What does Woonbelasting cost?
Nothing. There is no account, no subscription and no paywall. There are no advertisements and no third-party trackers.
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?
There is no account and no database holding your letter. What you type stays in this tab until you close it. The postcode and house number go to the server to look the home up; your name, address and any BSN go with the preview or the PDF. We do not write that letter to a file. Answers from the public registers stay in the server’s memory for a while, six hours by default. The privacy page has the detail.
