It is important for you to know what the WOZ value is. The WOZ determines, to some extent, the maximum rent for your property. However, this only applies to social rental housing.
The maximum rent for social rental housing is determined by a point system. The WOZ value can influence this. The Dutch government provides more information on this topic, which you can find on the page Hoeveel huur betaal ik maximaal voor mijn woning? | Rijksoverheid.nl
The WOZ value does not impact the amount of your RBG tax bill.
