Verified 21 April 2023 - Directorate for Legal and Administrative Information (Prime Minister)
The social contribution of solidarity of businesses (C3S) contributes to the financing of old-age insurance. All companies with a duty-free turnover of more than EUR 19 million must declare and pay C3S.
The social solidarity contribution of businesses (C3S) shall be paid when the following conditions are met:
- The company realizes a turnover duty-free greater than €19 million
- The company exists at 1er January of the year. The C3S is not due in the year of its creation.
Guadeloupe, Martinique, French Guiana and Reunion fall within the scope of the C3S.
FYI
Companies with a turnover before tax of less than or equal to €19 million are exempt from C3S and are not required to report C3S.
The following companies are affected by C3S:
- Société anonyme (SA), simplified share business (SAS), business of public limited liability (SELAFA)
- General partnership (SNC),
- Limited Liability Company (LLC), business of Liberal Practice (SELARL)
- Limited Partnership (SCA) and Limited Partnership (SCS), Liberal Limited Partnership businesses (SELCA)

Warning
Low-rent housing and building credit businesses, condominium businesses, mixed-economy building businesses, investment businesses, land-use businesses and rural establishment are exempt from C3S.
The plate of the C3S consists of the following elements:
- Amounts taxable at VAT: titleContent
- Amounts falling within the scope of VAT but which are exempt from VAT (lines A1, E1, E2 and F2 of VAT-3310-CA3).
The rate of the C3S is 0.16% turnover.
The calculation of the C3S is therefore:(CAHT: titleContent - 19 million ) x 0.16%
The C3S is covered by the Urssaf Provence-Alpes-Côte d'Azur (PACA).
