Effective January 1, 2024, a new legal provision requires the inclusion of the “property tax ID” in all lease agreements subject to the law of July 6, 1989. Specifically, all lease agreements must now include this 12-character numeric identifier, with the first two digits corresponding to your department number.
Why has the property tax ID become mandatory?
The mandatory inclusion of this tax identification number in residential leases is intended to modernize and streamline contractual and administrative relationships between landlords, tenants, and government agencies.
In particular, this will make it easier to identify rental properties, conduct audits, and cross-check information among tax authorities, the CAF, and other agencies.

Which housing units are affected?
This applies to all rental properties—whether unfurnished or furnished—used as a primary residence. Whether you are a landlord or a real estate agent managing rental properties, you must include this identifier on all lease agreements for unfurnished or furnished properties used as a primary residence.
Leases Not Affected
However, please note that this new requirement does not apply to:
- vacation rentals,
- mobility leases
- commercial leases
- roommate arrangements formalized through multiple contracts between each roommate and the landlord
- other agreements for temporary occupancy
Mandatory in 2028 for the French overseas departments and territories
For French overseas departments and territories such as Martinique, French Guiana, Réunion, and Mayotte, this requirement will not take effect until January 1, 2028.
Where can I find the property’s tax ID number?
Also known as the “fiscal property identification number, “ this identifier is listed on your property tax bill. It also appears in your personal or business account on the impots.gouv.fr website.
1. Log in to the impots.gouv.fr website.
2. Depending on your situation, log in to your personal or business account.
If you have lost your tax ID number or forgotten your password, follow these instructions.
3. Click the corresponding tab
➡️ For the “Personal” section, select “Real Estate.”
➡️ For the professional section, select “Procedures” and then “Manage My Properties”
4. Go to the “View” section for the property in question
If you own multiple properties, be sure to select the one related to your request. To avoid any errors, please verify that you are entering the tax ID for the residence itself, not for any outbuildings (basement, parking space, etc.).
You’ll find your home’s tax ID at the top of the description 👇
