Taxes: the procedure for accessing your personal space is evolving

On June 25, 2025, the General Directorate of Public Finance set up a double authentication system for access to your particular space on the impots.gouv.fr website.

When you log in, after entering your tax number and password, you must now enter a 6-digit security code ; this code is yours sent to the email address associated with your account impots.gouv.fr.

When you perform this dual-authentication connection on a device (computer, mobile phone, etc.), the device is recognized as “trusted”. For 6 months, you no longer need to perform the operation Dual authentication to connect, provided you use this “trusted” device with the same web browser. On the other hand, a new code to be filled in is sent to you by email:

• when using another device;
• when you connect to your particular space impots.gouv.fr from another web browser;
• if you delete cookies from the web browser you used for your login.

The Directorate-General for Public Finance states that the implementation of double authentication is a way to strengthen the protection of your personal and tax data, in a context of constantly increasing risks (fake emails, fraudulent calls, etc.).
