This year’s deadline for the “paper” version of your tax return is May 26, 2021 (midnight).

May 26th at midnight for the departments numbered 1-19
June 1st at midnight for the departments numbered 20 to 54
June 8th at midnight for the departments numbered 50 to 976.

A very general look at your income tax obligations in France
The French tax year extends from 1st January to 31st December.
It is up to you to complete your own tax return (la déclaration des impots) and hand it in for the deadline, usually on or around 31st May. Failure to meet the deadline could mean a fine of up to 10% of your unpaid tax bill, and the French tax officials are not known for their charitable acts!
To ensure it is received, hand it in yourself at your tax office or send by recorded delivery.
You may opt to pay in three equal instalments (tier provisionnel) or 10 monthly instalments (mensualisation) by direct debit.
Tax residents should simply visit their local tax office (Hotel des Impôts) to arrange this, whereas non-residents with tax obligations in France should contact the Centre des Impôts des Non-résidents, TSA 10010 – 10 rue du Centre – 93465 Noisy le Grand Cedex. Telephone: 0033 (0)1 57 33 83 00 – E-mail: email@example.com
