Published Last updated

The deadlines for submitting income tax returns in 2024 were confirmed to The Connexion by France’s tax authorities today (March 12).

Due to the high volume of declarations, there are, as usual, separate deadlines depending on where you live in France - or if you live abroad.

The deadlines for 2024 declarations (relating to 2023 income) are:

  • Before midnight on Thursday May 23 for departments 01 (Ain) to 19 (Corrèze), and for non-residents who have French income that must be declared

  • Before midnight on Thursday May 30 for departments 20 (Corse-du-Sud) to 54 (Meurthe-et-Moselle)

  • Before midnight on Thursday June 6 for departments 55 (Meuse) to 95 (Val-d'Oise) and overseas departments

Non-residents must declare any income that is assessable in France. This typically concerns people who rent out their property/ies in France.

The date when the online tax declaration service will open has not yet been confirmed but is likely to be in the first half of April.

Paper form deadline not yet announced

Most people with French income declarations to make do so online via the French tax website, however it is possible for some people, for example those without internet access at home, and those who cannot declare online due to age or disability, to do so on the traditional paper forms.

The deadline for when paper forms can be sent in has not yet been confirmed, however last year it was a few days before the first online deadline.

If you miss your deadline, your tax bill may increase by 10% by way of penalty. This rises up to potentially 40% if you ignore subsequent reminder letters.

The Connexion will be publishing our annual French Income Tax help guide at the end of March. It includes information on topics such as how to declare common kinds of income, how to claim tax credits and other ways of lowering your tax bill, and how your bill is worked out.
