How income tax works in France: the scale and the family quotient
French income tax divides your income by the number of shares in your household before applying the scale.
France taxes the household's net taxable income using a progressive scale. The household's income is divided by the number of shares (the family quotient), the scale is applied to each share, and the result is multiplied back. This means a family pays less tax than a single person on the same income.
The 2026 scale (income earned in 2025), per share
| Income per share | Rate |
|---|---|
| Up to €11,600 | 0% |
| €11,601 to €29,579 | 11% |
| €29,580 to €84,577 | 30% |
| €84,578 to €181,917 | 41% |
| Over €181,917 | 45% |
Worked example from the Ministry of Economy: €32,000, single
A single person has one share, so the income per share is €32,000.
11% of the slice from €11,600 to €29,579 is about €1,978. 30% of the slice from €29,579 to €32,000 is about €726.
The tax is about €2,704, which the Ministry's example gives as €2,703.58.
Family example: couple with two children, €55,950
With three shares each share has €18,650, taxed at 11% above €11,600, giving about €775.50 a share and €2,326.50 in total. Because that is under the €3,277 threshold for couples, the décote reduces it by about €430, to roughly €1,896.50.
✨ Key Takeaways
- Income is divided by your number of shares before the scale is applied.
- The reduction from the family quotient is capped per half-part.
- The décote reduces tax for modest incomes.
