Converting a SARL into a SAS
Updated March 2026 - Converting a French SARL into a SAS is often considered when the company grows, welcomes investors or needs more flexible governance. The move affects legal rules, the manager's social status and sometimes the tax position.
Why make the change?
Typical reasons include:
- ▸more flexible bylaws
- ▸easier investor onboarding
- ▸a different governance model
- ▸switching from self-employed manager status to assimilated employee status

Main steps
- ▸run a legal, social and tax diagnostic
- ▸appoint a transformation commissioner when required
- ▸approve the conversion and redraft the bylaws
- ▸complete the filing through the French one-stop shop
Costs and tax treatment
Formalities alone are usually not the main cost. The budget depends mostly on whether a commissioner is required and on the complexity of the new bylaws.
Tax neutrality is possible in many regular transformations, but it must be checked carefully, especially if the tax regime changes or if the operation is combined with other restructuring steps.
