The French income tax calculator (impôt sur le revenu) estimates your net salary after progressive tax bands, CSG, and CRDS social levies. France's household-based quotient familial system means tax is calculated per part fiscale, so filing status and dependents significantly affect your tax bill. This tool uses the 2025 barème de l'impôt and current social charge rates.

How to Use the French Income Tax Calculator
Understanding your French income tax (impôt sur le revenu) is more complex than most European countries because France uses a household-based system. Your tax is not calculated on your personal income alone — it depends on your household size via the quotient familial (parts fiscales). This calculator uses the 2025 barème de l'impôt to give you an accurate estimate of your net annual and monthly take-home pay, including CSG and CRDS social levies.
Step 1: Enter Your Gross Annual Salary
Enter your total gross salary before any deductions. In France, your employment contract typically specifies your gross salary (salaire brut). Before income tax is applied, French employers also deduct employee social contributions (cotisations salariales) of roughly 22–25% — the gross salary this calculator uses is after those deductions but before income tax and social levies (CSG/CRDS).
Step 2: Choose Your Filing Status and Parts Fiscales
France taxes households, not individuals. Select whether you are single (célibataire) or married/PACS. Then select the number of dependent children. A single person has 1 part, a couple has 2 parts, and children add 0.5 parts each (1 full part from the third child). More parts means your income is divided across more shares before tax, reducing your effective rate significantly — particularly for families.
Step 3: Review CSG and CRDS Deductions
Before the barème income tax is applied, two social levies are deducted: CSG (Contribution Sociale Généralisée) at 9.2% and CRDS (Contribution au Remboursement de la Dette Sociale) at 0.5%. Part of the CSG (6.8%) is deductible from your taxable income, which slightly reduces the income tax calculation. The calculator applies this automatically using the 2025 rates.
Step 4: Understand the 2025 Tax Bands
The French income tax bands for 2025 apply to your taxable income per part: 0% up to €11,497, 11% from €11,497 to €29,315, 30% from €29,315 to €83,823, 41% from €83,823 to €180,294, and 45% above €180,294. The calculator also applies the standard 10% professional expense abattement (capped at €14,426) before applying these rates, as required by French tax law.
Step 5: Check Your Monthly Take-Home Pay
The results show your annual and monthly net pay after all deductions. The effective rate shows the combined burden of income tax and social charges as a percentage of gross. The marginal rate shows your income tax rate on the next euro earned — useful for evaluating bonuses, freelance income, or investment decisions. For official French tax calculations, always consult an expert-comptable or the Direction générale des Finances publiques.
Frequently Asked Questions
Is this French income tax calculator free?
Yes, completely free with no signup required. All calculations run locally in your browser. You can use it as many times as needed to estimate your French net salary.
Is my salary data private?
Absolutely. All calculations happen entirely in your web browser. No salary figures or personal data are sent to any server. You can disconnect from the internet after the page loads and the calculator will still work.
What are parts fiscales (quotient familial)?
Parts fiscales determine your household's tax quotient. A single person has 1 part, a couple has 2 parts, and each of the first two dependent children adds 0.5 parts, subsequent children add 1 full part. Your total income is divided by your parts to find the taxable income per part, which is then taxed and multiplied back.
What is the difference between CSG and CRDS?
Both are social levies deducted at source on earned income. CSG (Contribution Sociale Généralisée) is 9.2% and funds the French social security system. CRDS (Contribution au Remboursement de la Dette Sociale) is 0.5% and was created to repay social debt. Together they total 9.7% on gross salary.
Which 2025 French tax brackets does this calculator use?
This calculator uses the 2025 barème de l'impôt: 0% up to €11,497, 11% from €11,497 to €29,315, 30% from €29,315 to €83,823, 41% from €83,823 to €180,294, and 45% above €180,294. These are the bands applied to income per part fiscale.
How does the abattement of 10% work?

Should I use this to file my French taxes?
No. This tool is an estimate for planning purposes only. French tax returns must be filed with the Direction générale des Finances publiques (DGFiP) via impots.gouv.fr. Always consult a tax professional (expert-comptable) for official advice.
