What is the France Income Tax?
France uses a quotient familial system: household income is divided by the number of "parts" (1 for a single person, 2 for a couple, plus 0.5 per child), taxed at progressive rates, then multiplied back. This gives families a substantial advantage.
Employee social charges of roughly 20–23% are deducted first, and a 10% professional expenses allowance applies before the bands.
Formula & worked example
Per part = Taxable / parts → progressive bands (0/11/30/41/45%)
Tax = Per-part tax × parts
Worked example: €60,000 gross for a single person with 22% social charges. After charges and the 10% allowance, taxable income is €42,120 in one part, giving income tax of about €5,740. Net take-home lands near €41,060 a year.
How to use this france income tax calculator
- Enter household gross income — France taxes the household, not the individual.
- Set family parts: 1 single, 2 married, +0.5 for each of the first two children, +1 thereafter.
- Adjust the social charges rate for your status.
- Note how adding parts sharply reduces the effective rate.
Smart tips
- The quotient familial is the biggest lever — a couple with two children has 3 parts, cutting the effective rate substantially.
- PER pension contributions are deductible from taxable income and are the main planning tool for higher earners.
- Tax is now collected at source (prélèvement à la source), but the annual declaration still reconciles it.
- The benefit of each additional part is capped, so very high earners gain less from children than the raw formula suggests.
- Non-residents are taxed on French-source income only, at a minimum rate of 20%.
