How it Works

French income tax (impôt sur le revenu) is calculated using a progressive bracket system. Each slice of income is taxed at a specific rate, ranging from 0% for the lowest incomes to 45% for the highest earners. This ensures taxation is proportional to each household’s ability to pay.

The quotient familial is a distinctive feature of the French tax system. It divides taxable income by the number of fiscal shares in the household, thereby accounting for family composition. This mechanism benefits larger families and couples with children by mechanically reducing the effective tax rate.

The décote is an additional relief mechanism for modest households. It reduces the gross tax when it falls below a threshold set annually by the finance law. In 2025, this threshold stands at €1,929 for a single person and €3,191 for a couple filing jointly.

Our simulator faithfully applies the 2025 scale and lets you instantly visualize the impact of each bracket on your taxation, as well as the effects of the quotient familial and décote on your final tax bill.

Frequently Asked Questions

What are the French income tax brackets for 2025?

The 2025 scale has 5 brackets: 0% up to €11,294, 11% from €11,294 to €28,797, 30% from €28,797 to €82,341, 41% from €82,341 to €177,106, and 45% above €177,106. These apply to the quotient familial (income divided by number of shares).

How does the quotient familial work?

The quotient familial divides taxable income by the household's number of tax shares (parts). A single person has 1 share, a married couple 2 shares, and each child adds 0.5 shares (1 share from the third child onward). Tax is calculated on the quotient then multiplied back by the number of shares.

What is the décote?

The décote is a rebate for low-income taxpayers. In 2025, it applies when gross tax is below €1,929 (single) or €3,191 (couple). It gradually reduces the tax payable to zero.

What is the difference between average and marginal tax rate?

The average rate is total tax divided by total income, reflecting the real tax burden. The marginal rate is the rate applied to the last euro earned, useful for assessing the fiscal impact of additional income.

Does this tool replace the official French tax return?

No. This simulator provides an indicative estimate based on the progressive scale. The actual calculation considers tax credits, deductions, categorical income, and special situations. Only impots.gouv.fr is authoritative.
