Definition
You have just declared 30,000 euros collected over the year as a non-regulated professional, and Urssaf has taken 7,680 euros, that is 25.6% of the declared amount in 2026.
On screen, a single line: social contributions.
Nothing says that part of that money buys a second layer of pension, the very one many new business owners believe does not exist in this status.
The supplementary pension is a compulsory scheme sitting on top of the Basic state pension.
In a micro-enterprise it is funded by a share of the flat-rate Social contributions calculated on the turnover you actually collect: you do not sign up for it, you are already paying for it.
Craftspeople, traders and non-regulated liberal professions belong to the self-employed supplementary scheme attached to Self-employed social security.
Regulated liberal professions belong to CIPAV, which runs its own supplementary scheme.
What your flat-rate charge really pays into the supplementary scheme
The rate you pay says nothing about where the money goes.
On 1 January 2026 the internal split of the charge changed without the headline rate moving: CSG-CRDS (the general social levies) gives ground to the contributions that build entitlements.
Here is what goes to the supplementary scheme out of every 100 euros of contributions paid in 2026, according to the breakdown published by Urssaf.
| Activity declared in 2026 | Supplementary share per 100 euros of contributions | On 30,000 euros collected in the year |
|---|---|---|
| Sale of goods (12.3%) | 19.75 euros | 728.78 euros |
| Commercial and craft services, BIC (21.2%) | 19.75 euros | 1,256.10 euros |
| Non-regulated professional, BNC under the general scheme (25.6%) | 21.00 euros | 1,612.80 euros |
| Regulated professional attached to Cipav (23.2%) | 30.70 euros | 2,136.72 euros |
How to read it.
A non-regulated freelance developer collecting 30,000 euros in 2026 pays 7,680 euros of contributions, that is 30,000 by 25.6%, of which 1,612.80 euros reach the supplementary scheme.
An architect attached to Cipav, on the same turnover, pays less overall, 6,960 euros at the 23.2% rate, and yet 2,136.72 euros go to the supplementary scheme, against 1,612.80 euros for the first.
These amounts are calculations, not officially published figures.
And those rates cover neither the vocational training contribution, nor the chamber levy, nor income tax, none of which fund any pension.
One sentence has been circulating since January: "in 2026 the pension share goes up for everyone".
It is false for non-regulated professionals, whose basic pension share falls from 47.60% of the charge in 2025 to 46.40% in 2026.
What rises for them is the amount in euros, because the overall rate moved from 24.6% in 2025 to 25.6% in 2026.
Paying is not always earning. A pensioner who starts trading again as a micro-entrepreneur pays the full charge, supplementary share included, without their pension rising by a single cent.
The same logic applies to arrears: entitlements are calculated on the contributions actually paid, never on the contributions due.
A late payment plan costs entitlements, not just surcharges.
Points, not quarters
The most common confusion sets two mechanisms against each other that have nothing in common.
The basic pension counts quarters.
For micro-entrepreneurs covered by the Assurance retraite, the general pension body, so outside Cipav, Pension quarter validation follows the rule of 150 hours of the hourly minimum wage as it stands on 1 January.
That works out at 1,803 euros of pensionable income for 2026, that is 150 by 12.02 euros. It is a calculation rather than a published amount.
The result is truncated, never rounded up to the next quarter.
The rise of the minimum wage to 12.31 euros on 1 June 2026 does not affect the current year's quarters, and the maximum stays at four quarters per calendar year.
The share of the charge allocated to the basic pension is converted into pensionable income using a ratio set by regulation, then compared with those 150 hours.
Outside the regulated liberal professions, the administration no longer publishes a turnover figure per activity: the official career statement is what counts.
Cipav members follow another path, their scheme not being part of the Assurance retraite: they are the only category for which Urssaf still publishes a turnover table per quarter.
The supplementary scheme ignores quarters entirely.
It accumulates points, bought by your contributions and converted into euros when the pension is drawn, using parameters the scheme sets and publishes each year.
Quarters decide when you can leave, points decide how much you get. A very good year will therefore never earn more than four quarters, but it will buy that many more points.
One last neighbour not to mix up: the Retirement savings plan (PER). The PER is voluntary saving, funded when you decide, with its own tax rules.
The supplementary pension is a compulsory charge, proportional to turnover, that you can neither refuse nor increase.
Frequently asked questions
Does ACRE relief reduce my supplementary pension?
No.
During the ACRE period, entitlements are calculated on the charge that would have been due without it, and the same neutralisation applies to the reduced rates of the French overseas departments.
One condition, and it is never optional: being up to date with payment of your contributions.
Employee and micro-entrepreneur: do I get two supplementary pensions?
Yes, the two schemes run in parallel and add up when the pension is drawn.
The ceiling of four quarters per calendar year changes nothing here: an employee already validating four quarters gains none from the micro-enterprise, but keeps building extra entitlements on top.
Can I pay more to improve my supplementary pension?
Not within the compulsory scheme.
The charge is strictly proportional to the turnover you collect and cannot be chosen: on 10,000 euros as on 60,000 euros, the supplementary share follows the same percentage.
The only voluntary lever left is personal saving, never a purchase of extra points.
Does a year without turnover count?
No. With nothing collected there is no contribution, therefore no point earned and no quarter validated, even though the declaration itself remains compulsory with a zero amount.
