Estimate your Cadastral Income online
Are you paying too much property tax?
It may be because of your Cadastral income.
Take the test:
In Belgium, the Property Tax is calculated based on the Cadastral Income (CI). However, the calculation of CI corresponds to the rental value of your property, depending on its location and its characteristics (comfort, age, etc.).
But this Cadastral Income was calculated by the administration... in 1975! It does not take into account changes in your property or the rental market.
To update the RC of each property, the FPS proposes a fixed indexation each year, common to all properties. It is 2.09 in 2023; which means that to calculate your Indexed Cadastral Income (2023), you simply need to multiply the RC by 2.09.
Example for a 2-bedroom apartment in Woluwe-Saint-Pierre:
Non-indexed cadastral income (1975): €860
Indexed Cadastral Income (2023): 860 x 2.0915 = €1,798
So does the 1975 RC still suit your property?
Not necessarily, and if that's the case, you may be paying too much property tax. There are ways to revise your cadastral income, but you still need to have arguments to justify a new cadastral income tax.

Answers to your questions about Cadastral Income
What is Cadastral Income?
Cadastral income (CI) constitutes the basis for the collection of property tax and for the determination of property income subject to personal income tax.
The RC is not a real income, but a fictitious income that corresponds to the average annual net income that a property would provide to its owner. It is therefore the average annual net rental value of the property at the reference time. Until today, this reference time is January 1, 1975.
What is the difference between Property Tax and Cadastral Income?
Cadastral income is determined at the federal level. Cadastral income does not have to be paid, but serves as the basis for calculating property tax and for determining property income subject to personal income tax.
Property tax is an annual tax payable based on indexed cadastral income. It is a regional tax . From now on, regions will process and collect property tax directly from properties located within their territory.
Why calculate my Cadastral Income?
Calculating your Cadastral Income allows you to better understand whether you are in a situation where you pay more Property Tax or less Property Tax than if you had your Cadastral Income updated by the administration.
When is it possible to reassess the Cadastral Income?
You can request a revaluation of the Cadastral Income after major modifications to your property (works).
The administration can also send you a notification of a change in your Cadastral Income: in this case, you have 2 months to contest this.
However, it is not possible to request a review of your cadastral income outside the specified claim period. The administration will only correct the cadastral income if it can be proven that a material error (e.g., clerical or calculation error) was made.
The purchase of real estate does not give the new owner the right to file a claim against the previously established cadastral income.
What is Indexed Cadastral Income?
The cadastral income (CI) taken into consideration for the registration of property tax and for the calculation of property income in the tax return is the indexed cadastral income .
By law, cadastral income must be reassessed every 10 years during a general equalization. Since this general revision has been delayed, cadastral income has been adjusted, since the 1991 income year, according to the consumer price index (automated indexation).
