Definition
You and your former salaried colleague earn roughly the same this year.
Same carte Vitale (health insurance card), same registered doctor, same refunds at the pharmacy: on that ground, nothing separates you.
Then comes the month when neither of you works, and the gap appears all at once.
Social protection for a micro-entrepreneur means every entitlement your Social contributions open up: refunds on medical care, maternity and paternity, daily benefits during sick leave, invalidity, death cover, a basic pension and a supplementary pension.
It is compulsory and automatic: it starts when you register, with no membership to apply for and no box to tick, and it is funded by a single charge proportional to the turnover you collect.
That is what the Self-employed social security label covers: a body of rules, not a counter to sign up at.
What the flat-rate charge buys, in euros
Take a non-regulated freelance graphic designer who collects 20,000 euros in 2026. Her contribution rate is 25.6% in 2026, so 5,120 euros over the year.
Urssaf publishes how that charge is split internally for BNC (non-commercial profit) activities under the régime général (general scheme); here it is converted into euros, rounded.
A regulated liberal profession affiliated to the Cipav does not read this table: it pays 23.2% in 2026, and its charge is split differently.
| What the charge funds | Share of the charge in 2026 | Out of 5,120 euros |
|---|---|---|
| Basic pension | 46.40% | 2,376 euros |
| CSG-CRDS (general social levies) | 25.20% | 1,290 euros |
| Supplementary pension | 21.00% | 1,075 euros |
| Invalidity and death cover | 3.30% | 169 euros |
| Health and maternity | 2.60% | 133 euros |
| Daily sickness benefits | 1.50% | 77 euros |
Three things stand out. These shares are calculated on the charge you pay, never on your turnover: the basic pension does not take 46.40% of 20,000 euros, it takes 46.40% of 5,120 euros.
The two pension lines together absorb 67.40% of the charge in 2026, which comes to 3,451 euros: your social cover is first and foremost a pension contribution.
And the line you use most, health, is the cheapest in the table at 133 euros for the year, because refunds on care do not depend on how much you pay in.
One reading point specific to 2026: for BNC activities the share going to the basic pension has fallen (47.60% of the charge in 2025, 46.40% in 2026), and it is the amount in euros that rises, because the overall rate went from 24.6% in 2025 to 25.6% in 2026.
The table says what the charge buys, it does not say who it buys for. These 5,120 euros open entitlements for the person who pays them and for nobody else.
A spouse who takes a regular part in the business without being declared builds nothing for those hours.
Collaborating spouse status, by contrast, opens entitlements in their own name, against contributions that come on top of yours.
The three gaps the charge does not fill
Unemployment first.
Losing your main client opens no unemployment insurance entitlement: a Self-employed allowance (ATI) does exist, but it comes with strict conditions on ceasing activity and on income, and it is nothing like the cover a dismissed employee receives.
Workplace accidents next: read the table again, no line is devoted to them. Falling down a staircase while delivering an order follows the same rules as catching flu.
Daily sickness benefits, finally, are indeed funded, at 1.50% of the charge in 2026 for a BNC activity; how much they pay and what opens them depend on your income and on how long you have been affiliated, and they are read on the Assurance Maladie website rather than guessed at.
Paying in is not enough: your entitlements are calculated on the contributions actually paid, not on those you owe. On identical turnover, someone up to date validates a quarter where someone in arrears validates none.
Pension quarter validation is where this shows up first, so unpaid contributions cost far more than the late-payment surcharge.
These gaps are filled by optional contracts you pay for yourself: Top-up health insurance for the share of care left to pay, and Personal protection insurance to keep an income coming during a long period off work.
Not to be confused with your business insurance
Many new business owners take out Professional liability insurance and believe their cover is sorted. The two subjects have nothing in common.
Business insurance repairs the damage you cause to a client; social protection covers you when health or age stops you working.
The first is a private contract, compulsory in some trades; the second is a mandatory scheme for everyone.
A second and costlier confusion: the contribution rate is neither a tax nor everything you pay Urssaf.
Income tax is settled separately, and the CFP (vocational training contribution) is added on top of the rate, 0.2% of turnover in 2026 for a liberal activity, and Acre relief does not cover it.
Finally, close to a quarter of what you pay, the CSG-CRDS, opens no personal entitlement whatsoever: it funds everyone's social protection.
Its share falls on 1 January 2026 in favour of the lines that build entitlements: for sales, BIC services and Cipav professions, whose overall rate has not moved, the same amount is taken and more rights are earned.
For BNC activities, that rebalancing comes on top of a rise in the overall rate.
Frequently asked questions
Does a quarter with no turnover cost me my cover?
You remain affiliated and your medical care is still refunded. The declaration stays compulsory: you enter 0 euros and pay nothing.
A period without income, however, opens no new entitlement, neither a pension quarter nor daily sickness benefits.
Does Acre relief shrink my social protection?
No. Your entitlements are calculated on the charge that would have been due without it, and the same neutralisation applies to the reduced rates in the French overseas departments.
One condition is never optional: being up to date with payment.
Does paying contributions alongside a salaried job improve my pension?
Four quarters at most are validated per calendar year: an employee who already validates four gains none on top, even though other entitlements do build up.
A pensioner paying contributions as a micro-entrepreneur increases neither the basic nor the supplementary pension.
How much must I collect to validate a quarter in 2026?
The rule gives one quarter per band of pensionable income equal to 150 hours of the hourly minimum wage on 1 January, which works out at 1,803 euros for 2026 (150 by 12.02 euros), a calculation rather than a published amount, and the result is truncated rather than rounded.
Outside the regulated liberal professions, the administration no longer publishes a turnover figure per activity: the official career statement is what counts.
For Cipav, Urssaf publishes 2,792 euros of turnover for one quarter in 2026, and 11,168 euros for four. Figures checked on 5 September 2026.
