We often talk about the WOZ value on our website. But what exactly is this?

The meaning

The term WOZ value derives from Real Estate Valuation Act (Wet waardering onroerende zaken. This law states that your home is regarded as immovable property and a value is assigned to it. The law calls the value of a property the WOZ value. A municipal official determines the WOZ value. You can find you value at WOZ-waardeloket .

The government uses the WOZ value to calculate taxes. Think of the sewerage levy (rioolheffing), property tax (onroerendezaakbelasting), water board tax (waterschapsbelasting) and notional rental value (eigenwoningforfait). In addition, it is also important for corporate income tax (vennootschapsbelasting), gift tax (schenkbelasting), inheritance tax (erfbelasting) and landlord levy (verhuurderheffing). Because all taxes use the same WOZ value, all the aforementioned taxes may be lower if you object. If you want to calculate your savings, take a look at our savings calculator.

The WOZ value also partly determines the maximum rent of a rental property. For example, the WOZ value is used in the calculation of the amount of points for a rental property. The WOZ value, together with other characteristics of the house, then determine the maximum rent of the rental property.

The value of your home therefore affects many taxes, etc., which makes it important that the value is determined as accurately as possible. After all, nobody wants to pay too much tax.

Because determining the value of your home is a decision of the municipality, you can object to the value according to article 22 WOZ. You can read further on the site in our WOZ-Wiki. The WOZ-Wiki has been specially created to explain the process of objecting to the value of your home and all additional matters as clearly as possible.
