Frequently asked questions

How much income tax will I pay if I move to Belgium?

Belgium has a progressive income tax system with four brackets ranging from 25% to 50%, plus a 7% communal tax surcharge on top of your federal income tax. After deducting your personal basic exemption of EUR 10,910 and a 30% employment expense deduction (capped at EUR 5,930), your remaining income is taxed according to these brackets, so your effective rate depends on your total earnings.

What's the difference between gross and take-home pay in Belgium?

Your take-home pay is reduced by employee social security contributions of 13.07% on your gross income, plus income tax and the communal surcharge. For example, a EUR 50,000 gross salary would have approximately EUR 6,535 in social contributions deducted, plus income tax calculated on the remaining taxable income after allowances and deductions.

Do I have to pay regional taxes in Belgium?
