The micro-entreprise, formerly called auto-entreprise, is the simplest French regime to start a sole business.
Contributions are a percentage of the turnover received, depending on the type of activity.
It is easy to declare, but real expenses cannot be deducted: it helps to know what you will actually keep.
What the simulator calculates
- Social contributions
- Net income, before tax
- Income after French income tax
- The effect of the flat-rate income tax option (versement libératoire)
- Monthly or annual figures
- Mixed activities (sales and services)
This official simulator is provided by Urssaf, the French social security agency (mon-entreprise.urssaf.fr). It loads from its website when you start it.
Indicative result, based on the figures entered and the rules known to date. It is no substitute for professional analysis: check your situation with a chartered accountant before deciding.
What next?
As the business grows, the micro-entreprise often becomes limiting: real expenses are not deducted, turnover thresholds apply and social protection is limited.
The standard regime or a company then takes over. To compare, see our self-employed contributions and SAS president salary simulators.
We will be glad to work with you as soon as you move to the standard regime or to a company. See how we start after incorporation
Frequently asked questions
How are micro-entrepreneur contributions calculated?
They are a percentage of the turnover received, with a rate that depends on the activity (sale of goods, services, liberal profession).
You declare your turnover monthly or quarterly and pay contributions at the same pace: no turnover, no contributions.
Does the simulator take my expenses into account?
No, because the regime does not allow them to be deducted: contributions and tax are based on turnover.
To see what you really keep, also subtract your business expenses from the income shown.
What is the versement libératoire?
An option to pay income tax together with contributions, as a percentage of turnover.
It is only available to households below an income threshold, and is only worthwhile in some situations: the simulator lets you compare.
When should I move to the standard regime or a company?
When your expenses become significant, you approach the turnover thresholds, or you want to hire, invest or better protect your assets and social rights.
We will be glad to work with you from that point. See how we start after incorporation
Are the results reliable?
The simulator is kept up to date with French social security rules by Urssaf.
It gives an estimate: in particular, it does not include the local business tax (CFE), generally due from the second year.
