Understanding your salary in Belgium (2026)
Belgium consistently ranks as one of Europe's highest-taxed countries for employees. With progressive tax rates reaching 50%, social security at 13.07%, and municipal surcharges on top, the difference between gross and net salary is significant. However, Belgium also offers a generous tax-free allowance and employment deductions that help lower earners.
Income tax brackets — 2026
Belgium uses four progressive tax brackets for income earned in 2026: 25% on income up to €16,320, 40% on €16,320 to €28,800, 45% on €28,800 to €48,320, and 50% on everything above €48,320. The tax-free personal allowance is €11,180, applied as a tax credit at 25% (worth €2,795 in tax reduction).
Social security contributions (RSZ/ONSS)
Employees pay 13.07% of their gross salary to social security, which is deducted before calculating income tax. This funds healthcare, pensions, unemployment benefits, and disability insurance. Employers pay an additional 25% (approximately) on top of gross salary — making Belgium one of the most expensive countries in Europe for employers. Social security contributions are tax-deductible, meaning they reduce your taxable income.
Municipal surcharge (Gemeentebelasting)
On top of federal income tax, every Belgian municipality charges a surcharge — typically 0-9% of your federal tax bill. The average varies by region: Brussels averages about 6.5%, Flanders about 7%, and Wallonia about 7.5%. This means the same gross salary can result in different net pay depending on your commune.
Employment expense deduction
Employees receive an automatic professional expense deduction (beroepskosten forfait). For 2026, this is calculated as a tiered percentage: 30% on the first €6,640 of net professional income, 11% on €6,640 to €13,220, and 3% above that, up to a maximum of approximately €5,520. You can also claim actual professional expenses if they exceed the automatic deduction.
