The service of your cadastral income

Once we have determined your cadastral income, you will receive a service notice. This is the official notice through which we inform you of your new cadastral income. Find out what is mentioned in your service notice and what you can do if you have a question.

  • For each new cadastral income you will receive a service via a registered letter. The service states the reason why we have allocated a new cadastral income. You will also find the characteristics of the immovable property on which we have based the cadastral income.

    • If you agree with the cadastral income, you do not have to do anything.
    • If you do not agree with the cadastral income, you can file an objection.

    The amount mentioned in the service is the non-indexed cadastral income, which is not the amount to be paid! A cadastral income is not a tax in itself. It is indexed and then serves as a basis for calculating other taxes:

    • For Belgian immovable property, it forms the basis for the property tax. This is a regional tax you must pay annually
    • For foreign and Belgian immovable property, it serves to determine the property income in the tax return.

    For questions about your service, please contact us on +32 (0)2 572 57 57 (normal rate). We are available every working day between 9 am and 5 pm. You can also make an appointment with the assessor who determined the cadastral income.

    • What is the difference between the useable area, the built area and the floor area in the service notice?

      Useable area

      This is a weighted surface area of ​​a property. It is calculated by multiplying the gross surface area of all parts and floors (including internal and external walls) of a property by a coefficient that reflects the usability of this part. The sum of these products is the useful surface area.

      Built area

      This is the area of ​​the perpendicular, horizontal projection of the building onto the ground surface.

      Floor area

      This is the sum of the gross floor areas (including internal and external walls) of all floor levels of the building.
