Social security contributions in France: What employers need to know
Social security contributions finance social protection in France. Understanding how they work, how they are calculated and how they are declared allows employers to secure their obligations.
In a nutshell
- Social security contributions fund social protection (health, retirement, unemployment, etc.).
- They are declared monthly via the nominative social declaration (DSN).
- Exemptions and reductions may lower employer costs depending on the situation.
What is the purpose of social security contributions in France?
In France, social security contributions consist of sums deducted from employees’ income to fund the social protection system. They are calculated based on salaries, as well as certain benefits and supplementary pay.
These contributions are primarily collected by URSSAF, the agency responsible for collecting social security contributions, centralizing payments and redistributing them to the various branches of social protection. This includes health insurance, retirement, family allowances, unemployment insurance and workplace accidents.
This mechanism ensures the shared financing of social risks and serves as a cornerstone of the French social model.

What are the different types of social security contributions?
Social security contributions are categorized by how they are funded. Some are paid by the employer, while others are deducted directly from the employee’s income.
Employer contributions
Employer contributions are paid by the employer in addition to the gross salary. They represent a significant portion of the total cost of an employee and fund:
- Social security (health, maternity, disability, death, basic retirement, family allowances and workplace accidents).
- Unemployment insurance and associated guarantees.
- Supplementary pension.
- Professional training.
- Various contributions, such as the mobility payment or the apprenticeship tax.
Employee contributions
Employee contributions are deducted directly from the employee’s gross salary to arrive at the net salary. They primarily cover:
- Social security contributions (old-age insurance).
- Social contributions (CSG, CRDS).
- Unemployment contributions (APEC for skilled employees).
Like employer contributions, they play a vital role in funding social protection.
How are social security contributions calculated?
The calculation of social security contributions is based on a structured mechanism. Each contribution is defined by a specific rate applied to a calculation base.
In practice, the calculation is carried out in three steps:
- Identifying the income elements subject to contributions (salaries, bonuses, benefits in kind)
- Applying the corresponding rates for each contribution
- Declaring and paying the amounts due via the DSN
Calculation rules may vary based on several parameters, including the business’s workforce size, the sector of activity, the salary level or the employee’s specific status. Certain contributions are capped or subject to specific conditions.
How to declare and pay social security contributions?
Social security contributions are declared and paid every month via the DSN. This mechanism centralizes all payroll-related information and allows for the automatic transmission of data to the relevant bodies.
Employers can handle this declaration themselves or outsource it to a third party, such as a chartered accountant. In either case, using DSN-compatible payroll software is necessary to ensure compliance.
URSSAF then collects the contributions and distributes them among the various social protection bodies. To learn more, visit the dedicated DSN portal.
Support from URSSAF
URSSAF offers a 12-month support program for businesses hiring their first employee. To find out more, log in to your personal account and go to the Contact section.
Are there any exemptions from social security contributions?
The French system provides several mechanisms to reduce the level of social security contributions under certain conditions. These exemptions may depend on:
- The business’s location, particularly in specific designated zones.
- Economic circumstances, in the event of exceptional situations affecting business activity.
- The business’s status, such as a new business startup or an innovative company.
- The employee’s salary level.
These mechanisms make it possible to adapt labor costs to the business’s situation while maintaining the funding of the social protection system.
