Net Salary Calculation: Complete Guide 2026

Introduction

The calculation of net salary constitutes one of the fundamental operations in payroll management within an organisation. Between the gross salary negotiated at the time of recruitment and the amount actually transferred to the employee's bank account, multiple social contributions, levies and deductions modify the final amount. In 2026, mastering this calculation remains a major concern for HR services and payroll managers, particularly in a constantly evolving regulatory context. This guide details the key steps in converting gross to net, incorporating the latest legislative changes and applicable rates.

From gross salary to net salary: the calculation steps

Gross salary corresponds to the total remuneration before deduction of social contributions. It includes the base salary, bonuses, overtime, benefits in kind and any commissions. From this amount, several categories of deductions are applied to obtain the net salary.

Employee social contributions represent approximately 22 to 25% of gross salary for a non-management employee, and up to 28% for a manager. They are broken down into several items: pension insurance (capped and uncapped), AGIRC-ARRCO supplementary pension, general equilibrium contribution (CEG), unemployment insurance (for certain categories), deductible and non-deductible CSG, and CRDS.

The main social contributions in 2026

CSG (Generalised Social Contribution) is applied at the rate of 9.2% on 98.25% of gross salary (for the portion below 4 PASS). Of these 9.2%, 6.8% are deductible from taxable income and 2.4% are non-deductible.

CRDS (Contribution to Repayment of Social Debt) is levied at the rate of 0.5% on the same basis as CSG.

Pension contributions include basic old-age contribution (6.90% capped + 0.40% uncapped) and AGIRC-ARRCO supplementary pension (3.15% on bracket 1 and 8.64% on bracket 2 for the employee portion).

APEC contribution (0.024%) applies only to managers.

Tax at source: net salary before and after tax

Since 2019, income tax at source is applied directly on the payslip. It is therefore necessary to distinguish between two concepts:

• Net salary before tax: obtained after deduction of social contributions

• Net salary payable after tax: amount actually transferred to the employee after application of the personalised rate transmitted by the tax authority

The withholding rate is communicated to the employer via the DSN (Nominative Social Declaration). In the absence of this, a neutral rate based on a rate table applies.

Specific cases to master

Certain situations require particular attention: overtime benefits from an exemption from employee contributions and a partial exemption from income tax (capped at 7,500 € per year). Restaurant vouchers, mandatory health insurance and transport expenses also receive specific treatment on the payslip. Finally, the social tax and the general reduction in employer contributions (formerly Fillon reduction) impact employer costs without modifying employee net salary.

Conclusion

Mastering net salary calculation is essential to ensure payslip compliance and respond to legitimate employee questions. With constantly evolving rates and the increasing complexity of schemes, the use of up-to-date payroll software and continuous training of HR teams are essential. An employee well informed about the composition of their remuneration is also a more engaged employee.
