End-of-year allowance
Last updated : May 13, 2026
The end-of-year allowance — often referred to as the “13th month” — is additional remuneration provided for in article 26 of the CCT SAS 2025.
Amount and payment
The allowance is equal to one twelfth of the sum of the base salaries paid to the employee during the year in question. It is paid:
- with the December salary, or
- at the end of the employment contract, in the event of departure during the year.
Under a regime of continuous presence, the amount therefore corresponds to one additional month of base salary.
Composition of the base salary
The base salary to be taken into account is made up of the following elements:
- the remuneration corresponding to the employee's career and seniority level, as set out in the grid in article 23;
- any function or responsibility premium.
Exclusions
The following elements are not included in the calculation of the allowance:
- supplements for night, Sunday and public holiday work;
- overtime;
- on-call allowances;
- holiday pay;
- 2025 one-off premium.
Special case — Dismissal for serious misconduct
The end-of-year allowance is not payable in the event of dismissal for serious misconduct.
