Social security contributions are normally paid by the manager himself, but in practice they are generally levied directly on the business' account. The contributions paid on behalf of the manager are deducted from the business' tax income.

The payment of contributions is made in two stages:

  • In December, the company receives only one installment call for assessment for the next year
  • In October, it receives a notification that the previous year's contributions have been adjusted according to the real income

Provisional contributions are paid either monthly (on the 5th or 20th of the month) or every 3 months (5 February, 5 May, 5 August and 5 November).

Payment can be made in one of the following ways:

Unassociated Manager

The manager has the status of a person treated as an employee: he depends, like the employee, on the general social security scheme.

The social contributions linked to the non-associated manager and paid by the company are the same as those of an executive employee, except unemployment insurance. The manager may, however, if he wishes, take out additional unemployment insurance.

He is covered by sickness and maternity insurance, family allowances, insurance against accidents at work, basic pension insurance, supplementary pension insurance and pension insurance.

Since he is not entitled to unemployment insurance, he does not have to pay the unemployment insurance contribution.

A manager who has a manager's social mandate and an employment contract may be eligible for unemployment insurance if Pôle emploi grants him or her unemployment insurance.

Social contributions and contributions shall be calculated on the following income:

  • Wages
  • Allowances
  • Supplementary social benefits
  • Accident at work Replacement income in case of sickness, maternity or
  • Extra-legal family benefits (additional benefits to those already provided by social security)
