How to File Income Tax in France
Filing deadline
The typical filing deadline in France is 31 May, though extensions may be available depending on your filing method and residency status.
How filing actually works in France
Income tax is withheld monthly at source (prélèvement à la source) based on your prior year's return, then reconciled through an annual declaration each spring.
Who needs to file
- Employees whose only income is salary may have tax fully withheld by their employer and may not need to file separately, depending on local rules.
- Self-employed individuals, freelancers, and business owners generally must file an annual return.
- Anyone with additional income (investments, rental property, foreign income) should check local filing thresholds.
Do non-residents need to file?
Residency status changes what you owe and whether you need to file at all. You are a French tax resident if your home or main place of stay (183+ days) is in France, your main professional activity is based there, or your center of economic interests is there. Non-residents are typically taxed only on France-source income, often at different rates or without access to resident-only allowances.
Steps to file
- Gather income statements (employer statements, invoices, investment income records) for the 2026 tax year.
- Determine your filing status and applicable deductions — see the deductions guide.
- Calculate taxable income and tax owed — use the calculator on this site as a starting estimate, and check the brackets guide for a worked example.
- Submit your return through Direction Générale des Finances Publiques (DGFiP) or with a licensed preparer before 31 May.
- Keep records for at least the period required by local law (commonly 4–7 years).
What happens if you file late
Most tax authorities charge a late-filing penalty (often a percentage of unpaid tax, sometimes a flat fee) plus interest that accrues daily until the balance is paid. Filing on time even without full payment usually avoids the larger late-filing penalty, leaving only late-payment interest to deal with.
This is general guidance, not tax advice. Filing rules vary by residency, income type, and year — confirm details with Direction Générale des Finances Publiques (DGFiP).
