Self-employed in France: social contribution withholding by platforms from 2026 | KAY Solutions
What is withholding at source for self-employed workers?
Until now, every auto-entrepreneur had to personally declare their turnover to the Urssaf (France’s social security collection body) and pay the corresponding social contributions. Although simplified under the micro-enterprise regime, this process remains a common source of forgotten deadlines, errors, and under-reporting — especially for those who earn income through digital platforms.
The new system changes everything: it is now the platform itself that calculates, withholds, and forwards your social contributions to the Urssaf. You no longer have anything to declare for income earned through that platform.
8 pioneering platforms launching as early as 2026
Without waiting for the official rollout in 2027, eight voluntary platforms are implementing withholding at source ahead of schedule in 2026:
Extracadabra
Les Sherpas
Mon Spécialiste Auto
StaffMe
Student Pop
Truckrs
Uber Eats
Wecasa
If you use one of these platforms, the Urssaf will notify you soon — in coordination with each platform — of the exact date your withholding at source will begin.
Why this reform? 3 key objectives
– Administrative simplification : No more monthly turnover declarations for your platform income. The platform handles everything with the Urssaf on your behalf, every single month.
– Protection of your social rights : Automatic and regular payment of your contributions guarantees access to your entitlements: daily sickness allowances, pension rights, and more. No more risk of losing benefits due to a forgotten declaration.
– Fairness and fraud prevention : The system helps limit the under-reporting of platform income and restores a level playing field between all independent professionals in France.
How does it work in practice?
The process is straightforward and requires no action on your part for the income concerned:
1/You carry on your activity through the platform as normal..
2/For each payment you receive via the platform, it calculates your social contributions using the rate provided by the Urssaf — based on your sector of activity and personal situation.
3/Each month, the platform sends your previous month’s turnover to the Urssaf and transfers the withheld contribution amount.
4/You can view the details of these monthly declarations (turnover + contributions) directly in your personal account at autoentrepreneur.urssaf.fr
Will your contribution rates change?
No. Withholding at source does not change your contribution rates or calculation rules. Everything remains identical to what applies to all auto-entrepreneurs in France — only the collection mechanism changes.
The platform simply applies the rate communicated by the Urssaf, tailored to your sector of activity and your situation.
What about income earned outside platforms?
Withholding at source only applies to income generated through participating platforms. Two situations remain your responsibility:
