Frequently asked questions
What are the French income tax brackets in 2026?
The 2026 scale has five brackets from 0 to 45 percent, uprated by 0.9 percent versus last year. The calculator applies the exact scale and shows your marginal and average rates.
Marginal versus average rate, what is the difference?
The marginal rate applies to your last bracket: it is what one extra euro of income costs. The average rate is total tax divided by income: it is what you actually pay.
How does the family quotient work?
Household income is divided into shares based on your family, the scale is applied per share, then the tax is multiplied back. The benefit of each extra half share is capped at 1,807 euros in 2026.
