Declare and pay your employees' social contributions and contributions

Verified 01 January 2024 - Legal and Administrative Information Directorate (Prime Minister)

Regardless of the contract, the employee receives a net salary after deduction of contributions and social contributions. It's theemployer that carries out the statement of those contributions to theUrssaf: titleContent (general case) or MSA: titleContent (if it is an agricultural activity). We'll explain everything to you.

In summary

Social contributions are sums (payments) deducted of the gross salary. They are prepayments on the gross salary, i.e. withheld before payment of the salary. The employee then receives the net salary that the employer pays him.

Contributions entitle the employee to a social protection in case of, for example, sickness, unemployment or when claiming pension rights.

It's theemployer who must calculate and declare the social security contributions of each of its employees to theUrssaf, or MSA (for agricultural professions).

The social contributionsmay be charged to:

  • either of the employee (wage share)
  • or the employer (employer's share). For example, the sickness contribution includes only an employer's share.
  • either of both


If you are an individual entrepreneur, micro-entrepreneur or equivalent employee manager, subject toincome tax, you should not be confused with your own contributions asself-employed. For more than details, you can consult our section I manage my taxes and contributions. Or our summary sheets on the subject such as: All you need to know about the contributions of your micro-company

General principle of calculation

They are calculated in percentage salary.

Of different rates correspond to each contribution (sickness, old age, unemployment, etc.). They are set by order in council.

The basis of the calculation may be some or all of the remuneration of the employee for his work performed.

The amount of contribution is the product of multiplication : the amount of remuneration (also known as the basis of calculation or the basis of assessment) multiplied by the rate in force.

Example :

Concerning theold-age insurance for pension entitlements, the contribution rate applies only to the part of the remuneration below a ceiling. This ceiling is called the annual social security ceiling (PASS). Its amount is fixed every 1er January. It stems from the Social Security Finance Act (SFSA). In 2023, for example, the monthly limit is €3,864.

Payment (payment) of contributions

The employer shall carry out payments, i.e. the payment contributions (employer's and employee's share) to the Urssaf (general case) or the MSA (in the case of an agricultural activity).

Payment of contributions open then the employees' rights their social protection benefits.

Please note

The social protection of the most employees and self-employed (unregulated craftsmen, traders and liberals settled from 2019) is insured by the general social security scheme. Only the self-employed of the regulated professions (lawyers, accountants, architects, etc.), micro-entrepreneurs settled before 2018 and the unregulated professions settled before 2019, have specific insurance funds (Cnavpl: titleContent and Cipav: titleContent).

The calculation rules and rates for each contribution are sometimes complex for a new employer.

Calculate the social contributions for the hiring of an employee and the expected remuneration

What are the contributory elements of the remuneration?

These are the following compensation elements:

  • Gross wages (e.g. overtime pay, night work allowances, tips, etc.)
  • Premiums and allowances (leave with pay, seniority, performance, periodic penalty payment, 13e months, strain, etc.)
  • Accident at work Replacement income and supplementary social benefits: the salary paid to an employee who is away from work, in order to maintain all or part of his remuneration during his interruption of activity (sickness, maternity or freedom from work)
  • Extra-legal family benefits (nursery premiums, family supplements)
  • Benefits (sums of money) provided by the Social and Economic Committee (ESC)
  • Benefits in kind (food and accommodation for example).

Please note

Where the employer makes available to the employed person a electrical terminal of vehicle charging located at the workplace, the benefit in kind from the use of this kiosk for non-business purposes is not recognized.

What are the non-contributory elements of remuneration?

The following elements included in the remuneration are not subject to contribution:

  • Per diem paid by social security 
  • Substitute earnings: retirement and invalidity pensions, unemployment and early retirement benefits 
  • Premiums linked to theprofit sharing or to the participation of employees to the company's performance (under a collective agreement) 
  • Bonuses related to the presentation of the Medal of Honor of Work, within the limit of the basic monthly salary 
  • Compensation considered as damages (severance pay)
  • Employer's supplementary pension and supplementary pension contributions
  • Reimbursement of professional expenses may be justified (e.g. catering costs, travel, purchase of clothing, etc.)

What is the minimum threshold and the social base ceiling?

The basis for calculating contributions may not be less than minimum remuneration legal or conventional (i.e Smic). This minimum tax base shall not apply to contributions calculated on a flat-rate basis. It does not apply to multi-card VRPs, interns and certain managers (those who are not bound by a company employment contract).

Conversely, some contributions are capped : beyond a certain amount or ceiling, remuneration is no longer taken into account for the calculation of contributions. This is the case for part of the old-age and Final: titleContent.

This ceiling is called the annual ceiling on social security. Its amount is fixed every 1er January. It stems from the Social Security Finance Act (SFSA). The amount taken into account is that of the monthly ceiling social security (PMSS). In 2023, for example, the monthly cap is set at €3,864.

Tableau - Social security ceiling by pay frequency










































The reward of a trainee, which is compulsory from 2 months of an agreed traineeship, shall be exempt from social security contributions if it is less than €4.35 per training hour. Above this threshold, it is subject to social contributions.

You can visit the Ameli website to learn more about the different ceiling amounts used :

  • Current year’s daily, weekly, monthly (PMSS), quarterly, or annual (Pass) PSS
  • Commonly used PSS multiples (e.g. 0.10% of the Pass)

The other contributions are due on the entire remuneration, they are said uncapped.

Please note

The CSG-CRDS calculation base is broader than that of social contributions. The non-contributory elements of remuneration are added.

Over what period should the ceiling be determined?

The determination of the social security ceiling for the calculation of social contributions shall be that of the period of work giving rise to remuneration.

The ceiling shall be adjusted in proportion to the time actually elapsed. That is, according to the pay periodicity.

Where the employee has not been present during the whole of that period, the ceiling shall be adjusted according to the days covered by the employment contract during that period.

Special rules apply to part-time employees and those excluded from monthly payments.

Example :

In the case of payment of the December salary at the beginning of January, the applicable social security ceiling shall be that of December.

This ceiling will also be applied to remuneration linked to the same pay payable for work performed, if any, in other periods.

  • Or do it yourself
  • Either assign it to a reporting third party such as a chartered accountant or to your human resources department
