Belgium salary after tax
Calculate your net take-home pay in Belgium for 2026. Includes income tax, social insurance, and all deductions.
Belgium has one of the highest personal tax burdens in the EU. The top rate of 50% kicks in at just €48,320, and employees pay 13.07% in RSZ/ONSS social security contributions before income tax is calculated. Municipal surcharges of 6-9% on top of federal tax add further. However, Belgium's extensive benefits system (meal vouchers, eco-cheques, company cars, hospitalisation insurance) means the real take-home picture is often better than the headline rate suggests.
