Belgium Personal Income Tax
Detailed personal income tax rates and rules for Belgium in 2026.
Belgium applies progressive federal income tax rates from 25% to 50%. A tax-free allowance (belastingvrije som) of approximately €10,160 applies, increased for dependents. Municipal taxes (commune surcharges) of 0% to 9% of the federal tax add to the burden. Belgium's three regions (Flanders, Wallonia, Brussels) have some tax authority, particularly over regional surcharges and certain deductions. The combined top marginal rate (including social security) can exceed 65% for employees.
| Income Range (EUR) | Tax Rate |

| €16K – €28K | 40% |
| €28K – €48K | 45% |
| €48K+ | 50% |

An individual is a Belgian tax resident if their domicile or seat of wealth is in Belgium. Residents are taxed on worldwide income. Belgium applies an irrefutable presumption of residency for persons registered in the Belgian National Register. Non-residents are taxed on Belgian-source income.
