Micro-entrepreneur simulator
Enter your annual turnover and activity type: the simulator computes your social contributions, your income tax (flat allowance or flat-rate payment) and what is left.
Loading the calculation model…
Calculations based on Urssaf's open source model (mon-entreprise.urssaf.fr), run in your browser. Indicative estimate: it replaces neither a payslip nor professional advice.
How to read the result
- Contributions are a percentage of the turnover collected, depending on the type of activity.
- Without the flat-rate payment, tax is computed on the turnover after a flat allowance, with the household's scale.
- With the flat-rate payment, tax is a percentage of the turnover, paid with the contributions. It has household income conditions.
- Business expenses are not deductible under the micro regime: the net income shown ignores your real costs.
What the simulator does not cover
Tax is estimated for a household with no other income: it will be higher if your household has other resources. ACRE, overseas departments, craftsmen's training contribution and the business property contribution are not detailed.
Frequently asked questions
What are the contribution rates of a micro-entrepreneur?
They depend on the activity: sale of goods, commercial or craft services, liberal services. The simulator applies the current Urssaf model rates and shows the effective rate.
What is the flat-rate tax payment?
An option to pay income tax together with the contributions, as a percentage of the turnover. It is open under household income conditions.
What if I exceed the turnover ceiling?
Above the ceiling for your activity you leave the micro regime. The simulator warns you when the turnover entered exceeds the threshold.
Does my net income include my expenses?
No. Under the micro regime, contributions are computed on turnover without deducting expenses. Subtract your real expenses yourself to find your disposable income.
