Updated on
Since 1 November 2026, withholding tax on pay has been calculated differently (Royal Decree of 27 September 2026). The calculations on this page still follow the previous rules: for pay received from 1 November, withholding tax and net pay may differ. Update in progress.
In Haacht, the municipal tax is 6.7% of the tax you owe the State for tax year 2026 (2025 income). For a single white-collar worker on €3,500 gross a month, it comes to about €543 a year on your 2026 income, assuming the rate is unchanged in 2027, €69 less than the Belgian average (7.55%).
