Managing payroll for a whole team? discover the Iberis HR Payroll module
Simulation based on the general CNSS regime (RSNA) and the 2026 IRPP tax scale, for an employee with no benefits in kind or specific bonus. Indicative result only: collective agreements, bonuses, benefits in kind or special regimes (manager, non-resident...) may change the exact calculation. For exact, multi-regime payroll, use the Iberis HR Payroll module.
How is net salary calculated in Tunisia?
Net salary is obtained by deducting the employee CNSS contribution (9.68%) from gross salary, then income tax (IRPP) calculated on an annual base after a professional expense allowance and family deductions, and finally the social solidarity contribution (CSS). Each step follows a precise legal rule, detailed below.

CSS (social solidarity contribution)
0.5% of the monthly taxable base, unless annual taxable income does not exceed 5,000 TND (full exemption in that case).

Does this calculation apply to all contract types?
This simulator applies the general CNSS regime (RSNA), the most common for permanent/fixed-term employees. Some statuses (non-salaried manager, CIVP contract, non-resident...) follow different rules not covered here — the Iberis HR Payroll module natively handles these multiple regimes.
