In the case of a posting, an employee may be sent abroad for a limited period of time (from one to a few years). All of their contributions continue to be paid to the French Social Security. The employee is exempt from local assessment that is required in those countries that signed a bilateral agreement with France.
In the absence of a bilateral agreement between France and the host country of the employee, there exists the obligation to settle local mandatory contributions.
The employee therefore continues to receive benefits paid by the French social security which may be supplemented by additional international coverage.
In the case of expatriation, the employee is sent abroad for a long time. Contributions to the French Social Security for this employee stop, but he can be a member of, and contribute to, the welfare regime of the country of expatriation.
The employee leaves the general scheme of the French Social Security and therefore no longer enjoys the benefits. Expatriation is recommended in the absence of bilateral agreements between France and the host country of the employee.
To maintain a link with the French general scheme, it is possible to join the Fund for French Abroad (CFE) and choose a supplementary international option. In other cases, a coverage called « the 1st Euro » should be envisaged.
