Are you thinking about setting up or have set up an SAS and would like to know the social regime that applies? We present you with the necessary information.
The president of SAS has the status ofemployee-equivalent : it depends, as does the employee, on the general social security system.
The social contributions linked to the manager and paid by the company are the same as those of an executive employee, except unemployment insurance. However, they may, if they so wish, also take out supplementary unemployment insurance.
He is covered by sickness and maternity insurance, family allowances, accident at work insurance, basic pension insurance, supplementary pension insurance and provident insurance.
Since the manager is not entitled to unemployment insurance, he does not have to pay the unemployment insurance contribution.
Social contributions and contributions are calculated on the following income:
- Salaries
- Allowances
- Supplementary social benefits
- Replacement income in the event of sick leave, maternity or accident at work
- "Extralegal" family benefits
- Cash benefits provided by the Social and Economic Committee (CSE)
- Benefits in kind such as food and lodging, provision of a professional vehicle for private use
