Income Tax FAQ — pick your country

This calculator uses the latest published Belgium tax brackets and personal allowance for the 2026 tax year, sourced from SPF Finances — federal PIT, simplified (excl. municipal surcharge ~7%).. Enter any gross salary above to see the bracket-by-bracket breakdown, your effective rate, and your marginal rate.

We start with your gross salary, apply the Belgium personal allowance and any standard deductions, run the result through the 2026 progressive income tax brackets, then subtract mandatory employee social-security and equivalent contributions. The number left is your annual and monthly net pay.

Yes. The Belgium calculator models employee-side social security, pension, health, and any solidarity or surcharge components that apply to wages. Employer-side contributions are excluded because they don't reduce your take-home pay.

It's a single-filer wage estimate that uses official 2026 rates. Your actual tax can differ based on filing status, dependants, regional or municipal taxes, salary-sacrifice arrangements, capital gains, and other personal credits. Treat the result as a strong first estimate, not tax advice.

At €100,000 gross per year, the model returns an effective tax-and-social-security rate of about 37.1% and a marginal rate of about 50.0% — leaving roughly €49,845 as annual take-home. Enter your own salary above for a tailored breakdown.
