Life is never dull in France and when it comes to taxes, the French tax authorities like to keep things interesting by making changes to the online tax system every year.
If you haven’t already, now is the time to make a start on your tax return or check with your tax adviser that they have all the documents and information that they need to complete your return for you. The deadlines for submitting the returns are as follows:
| Paper returns |
19th May 2026 |
| Department 01 to 19 |
21st May 2026 |
| Department 20 to 54 |
28th May 2026 |
| Department 55 to 974 and 976 |
4th June 2026 |

The paper returns must be put in the post box by midnight on 19th May.Whilst you can download our free Spectrum guide on your tax returns HERE, here are some tips that I have about doing the tax return given the recent changes to the system:
