TLDR: To access the online tax return, you must have been subject to income tax in the previous year. Use your tax number, online tax filer number, and reference tax income to obtain a password. Access is then available via the official website impots.gouv.fr using these credentials.
Who can file online?
You can access the online tax return if you were subject to income tax in the previous year. Taxpayers whose main residence is equipped with internet access are required to file electronically, except in cases of exemption (e.g., areas without mobile coverage until 31/12/2024).
Required credentials
To create your password, you will need three elements:
- Your tax number and your online tax filer number: these two numbers are listed on the first page of your last paper tax return or on a specific letter from the tax authorities.
- Your reference tax income: it is indicated on your last income tax notice.
Access procedure
- Go to the website impots.gouv.fr.
- Use your tax number and password to log in to your personal area.
- Access the section dedicated to the income tax return, where a pre-filled form corresponding to your tax situation will be provided.
Features of the online tax return
The online tax return offers several advantages:
- Pre-filled form: information known by the tax authorities (income, deductions, etc.) is already entered.
- Automatic checks: fillable fields are verified to avoid inconsistencies (e.g., inability to enter negative amounts).
- Online help: explanations are available for each field.
- Secure validation: the form cannot be validated if anomalies are detected.
Declaration and payment
The declaration and payment are two separate actions. After signing and submitting your return, you can make the payment:
- Immediately, via the "Payer" button.
- Later, while respecting the payment deadline.
Special cases
If you reside in an area without mobile coverage, you are exempt from the obligation to file and pay taxes online until 31 December 2024. In this case, use the other means provided by the tax authorities.
