Verified 19 September 2025 - Directorate of Legal and Administrative Information (Prime Minister)
Are you thinking about becoming or are you a micro-entrepreneur and want to know more about the social regime that applies? We present the calculation and payment rules.
The micro-entrepreneur benefits from a simplified regime for the calculation and payment of social security contributions.
These are calculated according to a fixed percentage applied to turnover.
This percentage represents one package that includes all social security contributions.
The declaration of turnover and the payment of contributions must be made to the Urssaf.
The declaration is to be made online, each month or each quarter, depending on the option chosen:
Micro-entrepreneur: online declaration of turnover (simplified micro-social regime)
Please note
The first declaration can be made at least 3 months (90 days) after the start of the activity.
Example :
In case of option for monthly declaration and payment: creation in September 2025 and declarations of the first 4 months of activity in January 2026, then every month.
If the turnover is equal to €0However, there are no social contributions to be paid.
The micro-entrepreneur can, however, ask to pay minimum social contributions.
The option to pay minimum contributions allows to continue to benefit from the guarantees linked to the payment of contributions despite a low or zero turnover.
In this case, the contractor switches to the self-employed ‘classic’: contributions are calculated on his professional income (to be reported once a year), instead of turnover. They are provisional, rather than definitive, and are then recalculated based on real income.
The request must be addressed to theUrssaf: titleContent (or at the general social security funds in the overseas territories) by post or by e-mail via the online account (reason: "Daily management of my account" > "I have another question regarding the management of my account") before one of the following dates depending on the situation:
- By 31 December for an application to 1erJanuary of the following year
- In case of creation of activity, no later than the last day of 3e month after creation.
To waive the option, the request must be addressed to theUrssaf: titleContent before 31 December of the previous year the year for which the option will no longer apply.
The social security contributions of the micro-entrepreneur are calculated monthly or quarterly according to his turnover or income in the previous month or quarter.
