Belgium Income Tax Overview
Belgium has some of the highest personal income tax rates in the world, reaching 50% quickly. Employee social security (13.07%) is deducted before income tax. A tax-free personal allowance and employment expense deduction also reduce the tax base. Municipal taxes (7% of income tax) apply on top.
Tax rules for expats in Belgium
Inbound Taxpayer Regime: Expats earning over €70,000 (2026 threshold) can receive a tax-free expense allowance of up to 35% for five years. This can be extended a further three years. Workers must be recruited from outside Belgium to be eligible, living more than 150km from the border for the previous five years before applying. (KPMG Belgium)

Estimate for relocation planning
This calculator provides a simplified estimate of income tax and mandatory social contributions. It is designed to help expats and relocating professionals compare take-home pay across countries, not to replace professional tax advice.
Assumes you are a full-year resident employee with a single gross salary.
Does not include deductions/credits, dependents, or special tax regimes.
What this calculator does
This tool provides an estimation of your take-home pay based on current Belgium tax laws. It factors in national income tax brackets and, where applicable, local or social security contributions to help you understand your net earnings.
How to use the calculator
- Enter your gross salary: Input your total annual or monthly income before any deductions.
- Select your frequency: Choose whether you are entering a yearly, monthly, or weekly sum.
- Review the breakdown: The tool will display your total tax liability, social contributions, and your final take-home pay.
Understanding your tax rates
When you see your results, you will notice two different rates:
- Marginal Tax Rate: This is the tax applied only to the next euro you earn. In a progressive system, this rate increases as your income moves into higher brackets.
- Average Tax Rate: This is your overall tax burden. It is calculated by dividing your total tax paid by your total gross income. It is almost always lower than your marginal rate because it accounts for tax-free allowances and lower-taxed lower brackets.
