tax return

It is the season of income tax returns in France. Whether you are submitting your details via the traditional paper form method or online at, here are all the important dates and deadlines you need to know about. 

Since 11th April, tax officials in France have been accepting income declarations for the 2023 tax year, but the final deadlines for submissions depend on where in France your main residence is located as well as your chosen method of submission. 

The final day for paper form-based declarations is 21st May.

The deadline for French departments numbered 01 to 19, which includes the Alpes-Maritimes, is 23rd May, while residents in departments 20 through to 54 get an extra week, with the deadline falling on 30th May. Departments 55 to 976, such as the Var, have more time still. Their deadline is set for 6th June.  

Everyone over the age of 18 who is considered to be a resident of France, i.e. you spend more than 183 days of the year in the country, must declare their income.  

If you notice an error on the form after it has been submitted, fear not. Corrections are possible in France until mid December.
