Frequently asked questions

How much income tax will I pay in Belgium as an employee?

Belgium uses a progressive tax system with four income tax brackets ranging from 25% to 50%. Your federal tax is calculated on your taxable income after deducting a personal basic exemption of EUR 10,910, a 30% employment expense deduction (capped at EUR 5,930), and your employee social security contributions of 13.07%. Additionally, a 7% communal tax surcharge is applied on top of your federal income tax, so your total tax burden includes both federal and local components.

What are the Belgium income tax brackets for employees?

The four federal income tax brackets are: 25% on income up to EUR 16,320, 40% from EUR 16,320 to EUR 28,800, 45% from EUR 28,800 to EUR 49,840, and 50% on income above EUR 49,840. These rates apply to your taxable income after allowances and deductions are applied, not your gross salary.

How much do I pay in social security contributions in Belgium?

As an employee in Belgium, you pay 13.07% in employee social security contributions on your gross income. The good news is that this contribution is tax-deductible, meaning it reduces your taxable income before your income tax is calculated, which lowers your overall tax burden.

What deductions and allowances reduce my taxable income in Belgium?

You receive three main deductions: a personal basic exemption of EUR 10,910, a standard employment expense deduction of 30% of your gross earnings (capped at EUR 5,930), and your employee social security contributions at 13.07% of gross income. These reduce your taxable income before the progressive tax brackets are applied.

Do tax rates vary by region in Belgium?

While this calculator uses averaged federal rates that apply across Belgium, regional communal taxes do vary slightly by location and are included here as a 7% surcharge on your federal income tax. The federal tax brackets themselves are consistent nationwide, but your exact total tax may differ slightly depending on which region (Flanders, Wallonia, or Brussels) you work in.
