The number of WOZ objections has decreased sharply in recent years, according to the Waarderingskamer (Valuation Chamber). This may be because municipalities are assessing more accurately. New rules limiting compensation to objection agencies may also play a role.
In 2023, the percentage of homes under objection in April was still 7.2 percent, or 595,000 homes. Last year, this fell to 3.9 percent (325,000 homes). The figures for 2025 in April show a further decrease to 3.3 percent (285,000 homes), the Waarderingskamer reports on Thursday.
The large decrease last year was probably due to stricter rules for agencies that specialize in WOZ objections. These agencies object to the assessed WOZ value on behalf of homeowners.
In the past, these agencies received high process cost allowances for this. But at the beginning of last year, these amounts were greatly reduced. This makes these activities less profitable for the agencies.
The WOZ value is determined annually by municipalities and is used to calculate the property tax and sometimes the sewerage charges for homeowners. These owners can object if they do not agree with the amount of the assessed value.
