Definition
Last day of an employment contract: HR explains that the company health plan will soon stop. Three weeks later the micro-enterprise is up and running, and the phone starts ringing.
Brokers offer the compulsory health cover for self-employed workers. That contract does not exist.
A mutuelle, which insurers call a complémentaire santé or top-up health insurance, is a private policy.
It reimburses the share of medical costs left to you by the Assurance maladie, the compulsory health insurance fund.
That share covers the ticket modérateur, the patient's own contribution, fees charged above the official tariff, and most of optical and dental care.
It never replaces compulsory cover, it sits on top of it.
In a micro-enterprise it is optional: no rule requires a self-employed worker to take one out. The obligation everyone has heard about applies to employers towards their employees, and you are not your own employee.
Your basic cover comes from the Self-employed social security, opened by your declaration of start of activity alone.
What your contributions already repay
Take 20,000 euros collected in 2026 from commercial or craft services.
The full rate for that activity is 21.2% in 2026, so 4,240 euros of Social contributions over the year, on top of which come the vocational training contribution (CFP), the chamber levy and income tax, none of which are included in that rate.
Urssaf publishes the internal breakdown of the charge as of 1 January 2026: health and maternity account for 8.80% of it and daily sickness benefit for 1.25%, so roughly 373 euros and 53 euros over the year.
These percentages are shares of the charge you pay, never shares of your turnover.
Those 373 euros buy exactly what an employee gets: a carte Vitale, a registered doctor, and a reimbursement calculated on the official social security tariff.
They buy nothing beyond that, and what lies beyond is precisely the ground a mutuelle covers.
One remark for anyone comparing two activities: under BNC in the general scheme, outside Cipav, the overall rate is 25.6% in 2026 and the health share 2.60% of the charge as of 1 January 2026.
The amount devoted to healthcare therefore differs from one activity to another, while the reimbursement itself is identical.
The trap closes at signature. A broker praises a loi Madelin policy (deductible cover for the self-employed) and its tax break, an unbeatable argument for someone taxed on actual profit.
In a micro-enterprise no real expense is deductible: not the mutuelle, not personal protection cover, not rent, not equipment. Your taxable income is calculated solely through the Standard allowance, set in 2026 at 34% for BNC and 50% for BIC services.
A health policy premium therefore comes out of your pocket after contributions and after tax, with no tax advantage whatsoever to expect from it.
Who pays what, item by item
The useful question is not whether compulsory cover reimburses, but where it stops. Here are the four items on which top-up health cover is worth its price for a self-employed worker.
| Type of expense | What the Assurance maladie takes on | What the mutuelle targets |
|---|---|---|
| Visit to your registered doctor | A reimbursement based on the official social security tariff | The ticket modérateur, never the flat patient charge |
| Fees charged above the tariff | Nothing, they are above the tariff by definition | All or part of them, depending on the policy |
| Glasses, dental work, hearing aids | Partial cover only | The remainder, up to an annual cap |
| Hospital stay | The care and the stay itself | The daily hospital charge and a private room |
Comparing two policies therefore means reading the third column, and nothing else: the rest is already paid for by your contributions. One point of vocabulary is worth clearing away here.
A policy sold as professional, or as reserved for the self-employed, remains an individual policy like any other for a micro-entrepreneur.
The commercial label opens no special tax treatment, and it changes neither the calculation of your contributions nor that of your income tax.
Health cover and income protection: two policies, two risks
Here is the most frequent confusion, and the most expensive one.
A mutuelle reimburses care, while Personal protection insurance replaces income. A back injury that keeps you off work for several weeks costs very little in medical fees, but takes your Turnover down to zero.
That risk belongs to the Daily sickness benefit of the compulsory scheme, funded by the line of the charge set aside for it, 1.25% under BIC and 1.50% under BNC as of 1 January 2026, and they require a minimum annual income and a waiting period without replacing a salary.
The mutuelle pays nothing at all in that situation, whatever its price bracket. Many new business owners buy the first policy and discover the gap on the day they stop working.
Frequently asked questions
Must a micro-entrepreneur hold top-up health cover?
No, and nobody can impose one.
There is no obligation to hold a complémentaire santé as a self-employed worker: calls and letters presenting it as a set-up formality are commercial offers, and should be treated as such.
I am keeping a salaried job on the side, do I need a second policy?
No. Your employer's health plan remains compulsory and keeps covering you, including for care received while you are working for your own clients.
Combining with employment creates no further obligation on that front, and two policies do not double the reimbursements.
What happens to my former employer's plan when I leave?
It continues for a limited time and free of charge, under the portabilité (continued cover) rules, provided you are receiving unemployment benefit.
The exact duration you are entitled to appears on the documents handed over when you leave. It also stops on the day your benefit does: that is the day the next policy has to be ready.
Without top-up cover, what is actually left for me to pay?
The ticket modérateur on every consultation and every medicine, fees above the official tariff, a large part of optical, dental and hearing care, and the daily hospital charge.
Two lines stay with you whatever you sign: the participation forfaitaire (flat patient charge) and the franchises médicales (medical deductibles), which a contrat responsable (compliant policy) is not allowed to reimburse.
Subject to a means test, the complémentaire santé solidaire (state-backed top-up cover) takes over: it is applied for at the Assurance maladie, never at Urssaf.
