French Income Tax Declaration Deadline for 2025 and Penalties for Late Filing
Tax Delinquency Solutions: Your Options if You Missed the Deadline
Stay informed about the exact dates and prepare your 2025 income tax declaration in advance to ensure accuracy and timely submission.
French taxpayers are required to file an annual income tax declaration to determine their tax liability based on the income earned in the preceding year. Whether submitted online or by paper, respecting the deadlines is crucial to prevent penalties and surcharges.
In 2025, the income tax declaration deadlines for different regions are as follows:
- Departments 01 to 19 and non-residents: Thursday, May 22, 2025 for online filing; Tuesday, May 20, 2025, for paper submissions.
- Departments 20 to 54: Wednesday, May 28, 2025 for online filing; as for paper submissions, the deadline remains the same as for other regions.
- Departments 55 to 976: Thursday, June 5, 2025 for online filing; paper submissions also follow the deadline for other regions.
What to Do If You Missed the Deadline
In case you realize your oversight after the deadline, it is crucial to file your income tax return as soon as possible, even if late, to minimize penalties. You can do this online on the tax website; late submissions are still accepted.
If you have legitimate reasons for your delay (such as health or administrative issues), you can request a waiver from the tax administration to reduce or cancel penalties. This request must be motivated and sent to your tax office.
Incase of an error in your declaration after the deadline, you can file an amended return via your personal space on the tax website, allowing you to modify or add missing information.
Penalties for Late Income Tax Declaration
Late interest is charged when you pay your taxes late, at a rate of 0.20% per month on the outstanding tax amount, calculated from July 1st following the year of revenue collection (2.4% per year). The administration may also apply a tax increase if it finds an error or omission in the declaration.
These increase rates vary from 10% to 80%, depending on the severity of the offense found and whether it was made intentionally or not. Refusal to cooperate with the administration during a tax audit can also lead to an increase in penalties.
The applicable increase affects the additional taxes claimed, and there is also an additional 0.20% interest per month of delay.
Stay informed, prepare your declaration early, and avoid financial penalties.

The exact dates will be confirmed by the French tax authorities nearer the time. For paper filers, the deadline will likely be in mid-to-late May.
