- The company has 60k budget.
- 25% goes to employer tax (charges patronales). 45k left. That's commonly called the gross salary (salaire brut).
- 25% goes to employee tax (charges sociales). 34k left. Commonly called the net salary (salaire net)
- Employee pays income tax at the end of the year. The rate is progressive and highly variable depending on personal situation. (30k left if you're single living alone).
Tip: Generally speaking I strongly advise to avoid discussing taxes with French citizens, fact is absolutely nobody understands where money goes to or how much. The usual payslip only shows the "charges sociales" itemized as 10 to 20 lines of things.
