Social Contributions for Micro-Entrepreneurs: Key Information
/in Blog /by escecVerified by Directorate of Legal and Administrative Information (Prime Minister’s Office)
Micro-entrepreneurs are subject to a specific social security system. This guide outlines the applicable contributions, declaration procedures, and potential exemptions.
Calculation and Declaration of Social Contributions
Micro-entrepreneurs benefit from a simplified system for calculating and paying social contributions. These contributions are determined as a fixed percentage of revenue and cover all required social charges.
- The calculation is based on revenue generated in the previous month or quarter.
- Contributions must be declared and paid to Urssaf either monthly or quarterly, depending on the chosen reporting schedule.
- Declarations are made online through the Micro-Social Regime portal.
Applicable Contribution Rates
Rates vary depending on the nature of the business activity:
- Retail trade and accommodation services (excluding furnished rentals and tourist lodgings)
- Furnished residential rentals
- Furnished tourist rentals
- Service-based activities (Industrial and Commercial Profits – BIC)
- Liberal professions outside Cipav (Non-Commercial Profits – BNC)
- Liberal professions under Cipav (BNC)
It is possible to estimate contribution amounts using an online simulation tool.
Revenue of Zero: Consequences
If no revenue is generated, no social contributions are due. However, micro-entrepreneurs can opt to maintain minimum contributions to preserve access to benefits such as health coverage and retirement rights.
- This request must be submitted to Urssaf by December 31 of the preceding year or, for new businesses, within three months of registration.
- To withdraw from this option, a written request must be sent before the end of the year.

Social contributions deducted from revenue cover:
- Health and maternity insurance
