Micro-Enterprise Management: Understanding Your Obligations Towards Urssaf

When you start your business, managing a micro-enterprise benefits from a simplified framework, but it still involves a number of obligations that must be respected. Between Urssaf declarations, social contribution payments, and accounting record-keeping requirements, it is best to understand the rules from the outset. Let’s take a closer look at the key obligations that structure the day-to-day management of your business as a self-employed entrepreneur.

Declaring Your Turnover: The Foundation of Micro-Enterprise Management

The first essential step in effectively managing your micro-enterprise is informing Urssaf each month or quarter of the turnover you have generated. This declaration is mandatory, even when your business has not generated any income during the period. When registering, you choose the reporting frequency that best suits your needs, either monthly or quarterly, and you must maintain that schedule throughout the year.

The turnover declared corresponds to the amounts actually collected, not merely invoiced. To remain eligible for the micro-enterprise regime, your business must also stay within specific annual turnover thresholds. In 2026, these thresholds are €203,100 for goods sales activities and €83,600 for service activities. Exceeding the limit during a single year does not automatically remove you from the regime. However, exceeding the threshold for two consecutive years results in a transition to the standard tax regime.

Other Tax Obligations for a Micro-Enterprise

Once your turnover has been declared, your social contributions are automatically calculated based on the declared amount. Subject to eligibility conditions, you may choose the simplified income tax payment option (versement libératoire). This option allows you to pay both your social contributions and income tax in a single payment through Urssaf.

If you have not selected this option, your micro-entrepreneur income is added to the rest of your household’s taxable income and must be reported each year during the income tax filing period. You will then pay income tax through advance payments deducted monthly or quarterly, unless you have opted for the versement libératoire scheme.

Managing Your Micro-Enterprise Day-to-Day: Invoicing and Accounting

Beyond administrative declarations, managing a micro-enterprise also requires compliance with certain accounting obligations. While these requirements are lighter than those imposed on traditional companies, they remain essential for staying compliant with French regulations.

Electronic Invoicing: A New Requirement to Prepare For

Micro-enterprise management is evolving with the gradual rollout of electronic invoicing between businesses. From 1 September 2026, you must be able to receive invoices in electronic format. You will then have until 1 September 2027 to issue your own invoices electronically. It is therefore advisable to prepare in advance by researching software solutions that are compatible with your business activities.

At the same time, every invoice you issue must continue to include all mandatory legal information and must display the words “Entrepreneur individuel” or “EI” before or after your name on all commercial documents.

Maintaining an Income Record Book: A Key Habit for Smooth Micro-Enterprise Management

Another essential accounting obligation is maintaining a record book that lists, in chronological order, the amount and source of every payment received as part of your business activity. For each payment collected, specify the payment method used and keep the corresponding supporting documentation.

If you benefit from the VAT exemption scheme, you must also maintain an annual register detailing your purchases of goods and services, as well as a day book recording your income on a daily basis.

Retaining Accounting Documents and Opening a Dedicated Bank Account

You must keep all invoices and supporting documents for ten years. In addition, once your turnover exceeds €10,000 for two consecutive years, opening a bank account dedicated to your business activity becomes mandatory. Below this threshold, it remains a recommended best practice, allowing you to clearly separate your personal and business finances.
