Are You a French Tax Resident?
You are a French tax resident (and must file French taxes) if any one of these applies:
- Your principal home (foyer fiscal) is in France
- You spend 183 days or more in France in a calendar year
- Your principal activity (work or business) is in France
- France is the center of your economic interests (main investments, bank accounts, business)
Once you meet any of these tests, France taxes you on your worldwide income — but the US-France tax treaty prevents double taxation through the Foreign Tax Credit mechanism.
2025 French Income Tax Brackets (Barème IR)
| Annual Income (per Part) | Tax Rate |
|---|---|
| Up to €11,294 | 0% |
| €11,294 – €28,797 | 11% |
| €28,797 – €82,341 | 30% |
| €82,341 – €177,106 | 41% |
| Over €177,106 | 45% |
Note: The quotient familial system (parts) reduces effective rates for families. Social charges (CSG, CRDS, prélèvements sociaux) add approximately 9.7–17.2% on top for certain income types.
How to File Your French Tax Declaration
- File online at impots.gouv.fr — online filing is now mandatory for all taxpayers with internet access
- First-time filer? Create an account using your numéro fiscal (tax number). Find it on any French tax document or request one from your local tax office (SIP)
- Deadline varies by department: late May to mid-June each year. Check impots.gouv.fr for exact 2025 dates.
- You declare: all French income (salary, self-employment, rental, investment), and also foreign income under specific categories
- Foreign income: use forms 2047 (foreign income) and 2042 (main return). Report US income in euros using ECB average exchange rate.
- Prélèvement à la Source: If employed, French income tax is withheld at source by your employer monthly. The annual declaration adjusts the final amount.
How to Avoid Double Taxation: Foreign Tax Credit
The US-France Tax Treaty (Article 24) allows you to claim a credit for French income taxes paid against your US tax liability. For most Americans in France earning income taxed at French rates (which are generally higher than US rates), this means little or no US tax is owed — but you still must FILE a US return each year. The FEIE (Foreign Earned Income Exclusion) is an alternative but choosing FEIE vs FTC requires careful analysis.
Key Deductions & Credits in France
Professional Expenses
10% abatement forfaitaire (flat deduction) on salary income — automatic. Or deduct actual expenses if higher (receipts required).
