Frequently asked questions

There are many differences between houses. It could be due to one of the following factors:

If everything is exactly the same, schedule a phone appointment with one of our appraisers. The appraiser will then immediately check if a mistake has been made and often adjust the WOZ value right away.

There are many differences between homes. It could be due to any of the following:

Make a call appointment with one of our appraisers if everything is exactly the same. The appraiser then immediately checks if a mistake was made. And often the WOZ tax base can be adjusted accordingly right away.

We determine the WOZ tax base by comparing with sales figures of comparable homes. These are based on sales figures from a year earlier. This is a national calculation procedure.

We also look at the differences between these properties. Consider differences such as whether or not you have a dormer or canopy. And difference in maintenance and amenities such as kitchen and bathroom, for example.

The appraisals are based on the rules set out in the WOZ Act (Special Act for Real Estate Assessment). It is not necessary to visit each property separately. The Netherlands Council for Real Estate Assessment audits all municipalities and Tax Authorities that determine the WOZ tax base.

Yes, you can see the values via www.wozwaardeloket.nl

Your valuation report is available in My RBG. It is also available on MijnOverheid – Wonen (residential).

Yes, that has been taken into account. Our appraisers base WOZ values on the prices of sold homes, among other factors. They check whether they can apply these prices and adjust WOZ values where necessary. In this case, they adjust the WOZ value downwards. They do this because the VCE share is not part of the property. This method applies to apartments and ground and upper-floor townhouses.

We will look at sales prices of comparable houses that have been sold between 1 January, 2023 and January 1, 2025. Were no comparable houses sold during this period? Then we look at previous sales prices. Naturally, there can be major differences in how houses have been constructed. That is why we look at the characteristics that can be compared. Such as:

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.

We will consider the situation of the residence on 1 January of the current tax year. If the dormer is present on 1 January, then it is counted towards the WOZ value. We do use the price level of the previous year.

Yes, you are obliged to give us information that is important for the WOZ value. We will only use your data to determine the WOZ value. We will not give your data to third parties. We are obliged to maintain confidentiality. This is all set in the State Taxes Act.

This allows us to better determine the condition of the sold property. With this, we determine the WOZ value. The answers enable us to compare properties more effectively. To determine the value, we compare properties with similar sold properties. We take into account the differences between the properties. We obtain these differences from many sources, including the completed questionnaires.
