Qu'est-ce que Net Salary ?
Definition
Net salary is the actual amount of remuneration that arrives in the employee's bank account each month after all mandatory deductions have been applied to the gross salary — specifically, ONSS/RSZ employee contributions (13.07%) and the payroll withholding tax (précompte professionnel). It is the amount available for personal spending and budgeting.
In practice
Calculating net salary from gross in Belgium requires accounting for multiple variables: the applicable ONSS/RSZ reductions (low-wage employees benefit from significant reductions), family situation (number of dependants, single/couple status), applicable tax deductions (transport allowance, professional expenses), and regional factors (Brussels Capital Region vs. Wallonia vs. Flanders may apply different regional tax credits). Online salary simulators (IPP simulator, Partena Professional salary calculator) allow candidates to estimate their net for a given gross. Key benchmark: a €3,500 gross monthly salary typically yields approximately €2,200–€2,500 net for a single person with no dependants. Including meal vouchers, group insurance, company car and other extra-legal benefits significantly changes the effective total net benefit.
Key takeaway
Net salary is the real-life figure — always verify it with a salary simulator before accepting an offer, as the gross-to-net ratio varies significantly depending on your personal and family situation.
