The United States taxes based on citizenship, not residency. A US citizen who moves to France remains subject to US federal income tax on worldwide income, the same as a citizen living in the United States. This principle, established in the Internal Revenue Code and upheld consistently by US courts, is the foundation of every compliance obligation discussed in this cluster.
France taxes based on residency. A US citizen who establishes French tax residency also becomes subject to French income tax on worldwide income. Without the available mitigation tools, the same income would be taxed twice, in full, by both countries. The mitigation tools exist specifically to address this overlap.
Understanding US tax obligations as an American in France requires separating two distinct tracks: income tax, and information reporting. Both tracks require annual attention, but they operate under different rules, different forms, and very different penalty structures.
The Annual Income Tax Obligation
Who Must File
Every US citizen must file a federal income tax return (Form 1040) each year, regardless of residence. The filing obligation does not require income above a threshold, although certain income levels do trigger the requirement even for citizens with minimal US connections. The income threshold is lower than most people expect, and the safest default is to file every year regardless.
Income Tax on French Income
French-source income is includable in US gross income. All wages, business income, rental income, capital gains, dividends, and interest earned in France are reportable on the US return. The two primary tools for preventing double taxation are:
Foreign Earned Income Exclusion (Form 2555). Allows up to $130,000 (2025) of foreign earned income to be excluded from US income tax. Only earned income (wages, self-employment income) qualifies. The exclusion requires qualifying under either the Bona Fide Residence Test or the Physical Presence Test (330 full days abroad). Full details on the FEIE.
Foreign Tax Credit (Form 1116). Allows French income taxes paid to offset US income tax liability, dollar for dollar. The credit applies to income tax paid or accrued to France, organized by income basket. For Americans in France, where marginal tax rates are often higher than US rates, the FTC typically eliminates US income tax liability on French-source income and may generate carryforward credits. Full details on the FTC.
The FEIE and FTC cannot be claimed on the same dollars of income. Choosing between them requires analyzing the taxpayer’s specific income composition, French effective rate, and long-term plans.
Common error: Assuming the FEIE eliminates all US tax. For self-employed individuals, the exclusion reduces income tax but does not eliminate US self-employment tax. Totalization agreement coverage determines whether US or French social security obligations apply.
Information Reporting
Information reporting is a separate compliance track from income tax. These forms do not assess tax; they report the existence and value of foreign assets and accounts to the US government. Penalties for failure to file information returns are often far larger than any associated income tax liability.
Key Information Reporting Requirements
| Form | Trigger | Threshold | Filed With |
|---|---|---|---|
| FinCEN 114 (FBAR) | Foreign financial accounts | Aggregate balance exceeds $10,000 at any point during the year | FinCEN (separately from IRS) |
| Form 8938 (FATCA) | Specified foreign financial assets | $200,000 on last day of year or $300,000 at any point (single/MFS); $400,000/$600,000 (MFJ) — higher thresholds for overseas filers | With Form 1040 |
| Form 5471 | Ownership in a foreign corporation | Various ownership thresholds; US shareholders of CFCs always required | With Form 1040 |
| Form 8621 | PFIC ownership (foreign mutual funds, ETFs, assurance-vie) | Any interest in a PFIC | With Form 1040 |
| Form 3520 | Foreign trusts, large foreign gifts or inheritances | Receipt of gift or bequest from a foreign person exceeding $100,000 | Separately from Form 1040 |
For most Americans in France, the FBAR and Form 8938 are the most commonly required information returns. French bank accounts, investment accounts, and assurance-vie policies all count toward the relevant thresholds. Full details on FBAR and FATCA reporting.
The PFIC Problem
French collective investment vehicles — including assurance-vie policies holding funds, Plan d’Épargne en Actions (PEA) accounts, and most French mutual funds — are classified as Passive Foreign Investment Companies (PFICs) under US law. PFIC ownership triggers Form 8621 filing and subjects income and gains to punitive US tax treatment unless a QEF or mark-to-market election is made. This is one of the most significant and underappreciated tax issues for Americans who invest in France using standard French investment structures. Full details on PFIC reporting.

Catching Up: Non-Filers and Late Filers
Americans who did not file US returns while living in France are not uncommon. Many were unaware of the obligation. The IRS offers the Streamlined Foreign Offshore Procedures specifically for this situation: non-willful non-filers who lived abroad during the years in question file three years of delinquent returns, six years of FBARs, pay any tax owed plus interest, and self-certify that their failure to file was non-willful. No penalties apply under this program.
Taxpayers who believe their non-compliance may be characterized as willful should seek qualified tax counsel before making any voluntary disclosure. The distinction between willful and non-willful failure to file has significant consequences for both the applicable program and potential penalty exposure. Full details on the Streamlined Procedures.
Technical Reference
Worldwide income inclusion: IRC §61 defines gross income as “all income from whatever source derived.” US citizens are subject to this provision regardless of residence. No treaty provision exempts US citizens from US income taxation on a general basis; the saving clause in Article 29 of the US-France tax treaty preserves the US right to tax its citizens as if the treaty did not exist.
Foreign Earned Income Exclusion: IRC §911. Maximum exclusion of $130,000 for 2025. Requires Form 2555 and satisfaction of either the Bona Fide Residence Test or Physical Presence Test.
Foreign Tax Credit: IRC §901–908. Computed on Form 1116. Available for income taxes paid or accrued to France. Income must be allocated to the appropriate basket. Credit carryforward is available for 10 years within the same basket.
FBAR: Bank Secrecy Act, 31 USC §5314. Filed using FinCEN Form 114. Due April 15 with automatic extension to October 15. Penalties for willful failure to file reach the greater of $100,000 or 50% of the account balance per violation, subject to inflation adjustment.
FATCA (Form 8938): IRC §6038D. Filed with Form 1040. Penalty for failure to file: $10,000, increasing to $50,000 if not filed after IRS notice. Assets reported on Forms 5471, 8621, 3520, and 8865 are exempt from detailed 8938 reporting but count toward the threshold.
