Chapter 8 Real property

The ownership of real estate is taxed through an advance levy on cadastral income. Cadastral income is a fictive revenue that used to correspond to the net annual revenue a building would generate for its owner if rented out on the market.21 Tax rates are set at regional level, on which provinces and municipalities can add “surtaxes”, which are expressed in percentages of the regional tax. Those surtaxes represent the main source of income for municipalities and provinces.

In 2020, the regional rates are:

  • 3,97% in Flanders
  • 1,25% in Brussels and Wallonia

Surtaxes differ by province and municipality. Averages by region (expressed in % of the regional tax) are given in Table 8.1.

Brussels 2996 989 3985
Flanders 896 173 1069
Wallonia 2579 1652 4231
