Goal and impact
The aim of the valuation process is to determine the most accurate WOZ value possible.
Rotterdam residents pay taxes based on the WOZ value.
Considerations
By determining the WOZ value using this application, the value can be determined faster and more effectively. The valuation chamber monitors the proper execution of the WOZ valuation.
Human intervention
There is an assessment by a valuer between the application outcome and sending the WOZ value.
Risk management
Legal basis
Valuation of Immovable Property Act + Municipal Act + Real Estate Tax Regulation

Technical design
Every year, the municipality of Rotterdam determines the WOZ value for your home. The WOZ value is stated on the municipal tax assessment notice. The WOZ value is the value of a building on a specific reference date. Based on this value, you pay taxes to the municipality, the water board and the Tax Authorities. When determining the WOZ value, the municipality assumes what the value would have been on 1 January of the previous year. This date is the valuation date.
Based on the WOZ value, the government levies three different taxes. The municipality levies real estate tax (OZB) from owners of a home. In addition, the government uses the WOZ value to determine the water board tax and to determine the owner-occupied home tax for income tax.
