The social solidarity contribution of companies (C3S) is a tax

based on turnover

Exemption thumb

The C3S is based on the turnover declared for VAT purposes after applying an allowance equal to 19 million euros. Its rate is, in principle, 0.16% of declared turnover.

A tax whose amount may seem limited but which can quickly constitute a significant burden for companies with a large turnover and a low margin.

It is therefore essential to take an interest in the functioning of this tax and the various preferential regimes that make it possible to limit its impact.

Who is affected by C3S?

In principle, all companies are subject to C3S (SA, SAS, SNC, persons governed by public rights, foreign companies operating in France and GIEs). The C3S applies in mainland France but also to companies established in overseas departments such as Guadeloupe, Martinique, Réunion and Guyana.

On the other hand, several companies expressly covered by the texts are exempt from C3S (low-rent housing companies, condominium real estate companies, press editor companies, maritime cooperative companies, etc.).

What is the amount of the C3S?

The C3S is calculated on the basis of the total turnover declared to the tax authorities under VAT.

The rate is fixed at 0.16% in principle with an allowance of 19 million.

Thus, a company that generates a turnover subject to C3S of 30 million euros will in principle only be subject to C3S on a taxable basis of 11 million euros.

However, this rule is subject to several exceptions in order to limit the weight of the social solidarity contribution of companies for certain sectors.

Are there reduced C3S rates?

Several reduced C3S rates are applicable. Some companies may benefit from a reduced tax base or benefit from a reduced C3S rate only on their gross margin. In this case, the C3S rate is 3.08% of the gross margin.

What sanctions?

The C3S return must be filed by May 15 of each year and the C3S must be paid by the same date.

Increases for late reporting amount to 10% of the contribution due, while late payment leads to the application of a 10% increase, automatically increased by an increase of 4.8% per year or part of a year of delay.
