What is the withholding tax deduction?

The deduction at source of income tax entered into force on January 1, 2019, in accordance with ordinance no. 2017-1390 of September 22, 2017.

Why is the withholding tax rate updated?

the withholding tax rate is calculated from the items entered in your last tax return and the corresponding gross tax. Thus, since January 2022, you pay withholding tax on your income at a rate which has been established on the basis of your 2020 income tax return (filed in May or June 2021) and your 2021 tax (calculated on your income of 2020).

From September 2022, your rate will be updated based on the items entered in your tax return 2021 (filed in May or June 2022) and your 2022 tax (calculated on your 2021 income).
