The tax-free allowance (quotite exemptee, a credit of about 2,795 EUR for a single person), the professional-expenses deduction (30% of income after social contributions, capped 6,070 EUR), and the communal surcharge (taxe additionnelle communale) are all applied on income after social contributions. The surcharge uses a representative 7% of the tax and varies by municipality from 0% to about 9%. The surcharge is computed on the tax before the allowance credit, over-stating it by about 196 EUR where the credit is fully used. Per-dependent increases to the allowance are not modelled.

🇧🇪 Belgium

Belgium has one of the highest marginal tax rates in Europe (50% above €51,070). However, the BBIB regime (introduced January 2022, replacing the old "special tax status for expats") provides a tax-free cost allowance of up to 35% of gross remuneration for income tax, uncapped since income year 2025 (30% capped €90,000 for social security). Social security is 13.07% of gross salary with no cap. Tax is calculated on gross salary minus social security contributions.
