Understanding the Income Tax Scale in France (Taxation en France)

When it comes to taxation en France, income tax is calculated using a progressive tax scale. This system divides your taxable income into brackets, with each bracket taxed at a different rate ranging from 0% to 45%.

How the Progressive Tax Scale Works

To apply the tax scale, you must first calculate your family quotient, which is determined by the number of parts (or shares) in your household. These parts reflect your marital status and the number of dependents. Your taxable income is divided by the number of shares, and the tax is calculated per share before being multiplied by the total number of shares.

ℹ️ Note: The income tax scale is updated annually through the Finance Law. For instance, the 2025 tax scale applies to income earned in 2024.

  • The marginal tax rate (TMI) is the rate applied to the highest portion of your income.

  • The average tax rate is your total tax divided by your total income, indicating what proportion of your income goes to taxes.

The Impact of the Family Quotient and Its Cap

The family quotient significantly affects your final tax bill. However, the tax benefit for dependents is capped, which means there’s a limit to how much your tax can be reduced based on family size.
