Do I need to declare my transactions?
In France, capital gains are subject to a single flat-rate withholding tax and are taxed at a global rate of 30%. You will therefore have to declare your taxable transactions when you file your taxes. In accordance with article 150 VH bis of the French General Tax Code, the total capital gain realized during the year is taxable if the total of all sales exceeds 305 euros.

When should I do my tax declaration?
Your capital gains must be declared each year when you file your taxes. The dates are different depending on the country in which you are a fiscal resident.
Your capital gains must be declared each year even if you have already declared them the previous year. It is always for the year N-1. Effectively, if you opened an account in 2022, you will have to report it in 2023 during the 2022 tax filing season.
