Even if income tax is deducted at source, you must declare your income and file your taxes each year, starting the year after your arrival in France.
This allows the tax authorities to bring your tax status up to date, adjust your withholding tax rate, and issue you a tax notice (‘avis d’impôts’).
When to file your tax return
Tax returns should be filed between April and June of each year.
The exact deadlines for filing returns are determined each year and vary depending on your département of residence and whether you file your tax return online or by post.
You must always meet the applicable deadlines when filing your tax returns.

How to file your tax return
You are filing a tax return for the first time in France
The first annual tax return for newcomers in France must be made using paper forms, which should be sent to or handed in at the Centre des Finances Publiques.
(Unless you have received a letter from the tax office inviting you to file your return online).
The main tax return form is form "2042 : Déclaration de revenus".
It can be collected from your local tax office or
downloaded from the impots.gouv.fr website.
The tax return form to declare income received in 2025, for the 2026 tax return campaign, will be available by the end of April, under the tab "Millésime 2026".
In addition to the completed, dated and signed 2042 form, please remember to provide:
- a copy of your identity document: passport (identity page and Schengen entry stamp if applicable), residence permit,
- a RIB (your bank details),
- proof of residence in France (see form 2042 for more details).
Other documents may be useful depending on your situation during the year concerned by the declaration, for example:
- if you worked: a copy of your last payslip and your employment contract,
- if you were doing an internship: a copy of your work 'convention de stage',
- if you were receiving a grant: a copy of your grant notification,
- if you were a student: a copy of your proof of registration ('certificat de scolarité'),
- if you have a bank account outside of France: the form 3916 completed, dated and signed.

The automatic tax return
If you are eligible for the automatic tax return system with a pre-completed form, the tax authorities will duly inform you of this – either by email or by post.
You should always check the information entered on the pre-completed form.
If this is correct, you don't need to do anything and your tax return will be validated automatically.
If you need to change or add any new information, however, you will need to modify and complete the relevant items.

The online tax return
If you are not eligible to use the new pre-completed / automatic tax return system, you should complete your tax return online via your
personal account ('espace Finances publiques') on the impots.gouv.fr website.
Important
There are many
international conventions, in particular with a view to preventing double taxation.
If your country has signed a convention with France, remember to indicate this when filing your tax return.
