Qu'est-ce que Gross Salary ?

Total remuneration agreed in an employment contract before deduction of employee social security contributions and withholding tax.

Definition

Gross salary is the total contractual remuneration for an employee before any mandatory deductions — specifically before employee social security contributions (ONSS/RSZ — approximately 13.07% of gross) and payroll withholding tax (précompte professionnel/bedrijfsvoorheffing). It is the figure stated in the employment contract and referenced in pay slips.

In practice

The relationship between gross salary and what the employee actually receives (net salary) in Belgium involves two key deductions: employee social security contributions (13.07% flat rate) and withholding tax (progressive rate depending on gross income, family situation and applicable reductions). A gross salary of €4,000/month typically yields approximately €2,500–€2,700 net depending on personal circumstances. The total employer cost (cost-to-company) is higher still: the employer also pays employer social security contributions of approximately 25% of gross salary, plus any extra-legal benefits. When comparing offers in Belgium, candidates must be aware of these significant gaps — a gross salary figure alone does not allow direct comparison without understanding all components of the total package.

Key takeaway

Always compare offers on a gross-to-gross basis and understand the total compensation package — the net salary is the relevant figure for day-to-day budgeting but gross drives most comparisons and negotiations.
