In L’Echo – 27 May 2026
Brussels’ taxation of office real estate is particularly high, with a property tax rate of 58.48%, compared with 55.22% in Wallonia and 47.22% in Flanders.
The capital therefore remains the most heavily taxed Region, notably due to the weight of municipal surcharges. In 2026, eight of Brussels’ 19 municipalities increased these surcharges, by an average of 20%. In addition, there is a specific regional tax on non-residential buildings, as well as an additional tax on office buildings in almost all Brussels municipalities. A tax on parking spaces is also levied throughout Brussels, with a few exceptions.
