Yes. As soon as you start renting out a furnished property in France—whether it's under a traditional lease or short-term rental (like Airbnb)—you must obtain a SIRET number. This requirement applies even if you rent occasionally or on a non-professional basis.
Why is a SIRET number required?
Furnished rentals are considered a commercial activity under the BIC (Industrial and Commercial Profits) tax regime. As such, the landlord must register with the authorities.
How to obtain a SIRET number?
Registration is free and can be done online through the one-stop portal for business formalities (which replaced the Business Formalities Centres in 2023):
Steps:
-
Create an account
-
Choose “rental of residential properties” in the business activity form
-
Upload the required documents (ID, proof of address, etc.)
-
Once validated, your SIRET number will be issued
This number is essential for your tax reporting (income declaration, LMNP or LMP registration, etc.).
Important Notes:
-
The SIRET obligation applies to all furnished rental landlords, including individuals who are not professionals.
-
If you fail to comply, you risk tax penalties.
-
In some cities like Paris, additional formalities may be required, especially for short-term rentals (e.g., registration number, change-of-use authorization, etc.).
