How Onroerende Voorheffing is Calculated
The annual property tax assessment in Belgium combines regional, provincial, and communal taxes:
- Indexed KI: The historical cadastral income (KI) from 1975 is indexed annually (indexation coefficient approx. 2.1763).
- Regional Base Tax:
- Flanders: 3.97% of indexed KI.
- Wallonia and Brussels: 1.25% of indexed KI.
- Opcentiemen (Surcharges): Municipalities and provinces levy additional surcharges (opcentiemen / centimes additionnels) calculated on the regional base tax, representing the largest portion of the final bill.
- Reductions: Homeowners with at least two dependent children entitled to child benefits qualify for a regional reduction (in Flanders, approx. €8 to €15 per child or percentage relief for modest dwellings).
