First check whether an objection stands a chance

Compare your WOZ value per m² with similar homes in your street. It takes ten seconds and uses the same public data the municipality uses. If your value is clearly above the street level, you have concrete evidence for your objection.

Where do you send your objection?

The municipality of Wormerland has outsourced its municipal taxes to Cocensus. Your objection therefore does not go to the town hall, but to:

Cocensus
T.a.v. de Inspecteur Belastingen
Postbus 16
1960 AA Heemskerk

You can also file your objection with Cocensus online, usually with DigiD. File the objection digitally

Always check the address against your own WOZ decision. Agencies and postal addresses change occasionally, and an objection sent to the wrong address misses the deadline.

The deadline: six weeks from the decision date

You can object up to six weeks after the date on the WOZ decision. In Wormerland the decision usually arrives late February, so the deadline runs to early April. Miss it and your objection is declared inadmissible, and its substance no longer matters. Running out of time? Send a pro-forma objection to secure the deadline.

Objecting is free, no agency needed

You do not need a no-cure-no-pay agency to object. The municipality treats your own objection exactly like an agency’s, and filing it yourself costs nothing. This site lets you check your value and produce a complete, legally correct objection letter as a PDF, entirely free.
