Why You Need to Log In to Your Personal Tax Account

Your personal account on impots.gouv.fr stores private tax information, so it is protected for confidentiality. Whether you are an employee of a French company, a freelancer, or a foreign resident, your personal account is necessary to:

  • File and pay taxes

  • View your tax notices

  • Track your personal tax situation

Every member of a household can log in individually with their tax number, making it possible for each to manage the household’s tax responsibilities.

Finding Your Log-In Information

Your Tax Number

If you’re wondering, “I work with a French company—do I have a tax ID?”, your tax number is the answer. It’s a 13-digit identifier found on:

  • The first page of your latest income tax return

  • Any official tax notices, such as income or local taxes

If you’ve already created an account but lost this number, click “Où trouver votre numéro fiscal ?” on the impots.gouv.fr website and follow the instructions to receive it by email.

🔐 Tip: Keep this number safe. You’ll need it each time you log in.

Your Online Access Number

This number is also located on the first page of your latest income tax return. You might also find it:

  • If you are 20+ and filing for the first time after being listed under your parents’ tax household

  • On your spouse’s online tax return (if they already created an account)

This number changes yearly—always use the latest one.

Your Base Taxable Income

This figure appears:

  • On the cover page of your most recent income tax assessment (under “Vos références”)

  • Or in the “Renseignements complémentaires” section of your tax notice

If you were declared under your parents’ household, simply enter “0” in this field.
