I’m a profession liberale (BNC) microentrepreneur, paying monthly social charges based on turnover to USSAF since 2020.
However, for the 2024 financial year impots have charged additional prélèvements sociaux (CSG - CRDS and PREL SOL) totalling 17.2% of assumed profit of 66% of turnover.
Is this additional charge correct? If so, it brings my total social charges up to around 35% of turnover (or 53% of assumed profit), which is much higher than anticipated.
If I have been charged incorrectly, what is the procedure for challenging the excess charges?
Many thanks for any light you can shine on this.
