Belgium has one of Europe's biggest gaps between gross and net pay. Enter your gross salary, pick your commune, and see what actually lands in your account each month — after social security, income tax and the Brussels communal surcharge.
Estimate. Belgium's gross-to-net has several moving parts (social security, the work bonus, progressive brackets, your commune's surcharge). This lands within ~1–2% of the SD Worx / official payslip figure for a single person. Pick your commune and confirm at fin.belgium.be.
Your salary before tax — Belgian contracts usually state this per month (×13.92 with holiday pay + 13th month).

The communal surcharge (4.9%–7% of your income tax) is the only Brussels-specific swing — it's settled at your annual tax return.
