Returning to France from the United States: American citizenship, green card, and expatriate status

Returning from the United States triggers obligations on both sides. As soon as a criterion for French tax residency is met, France imposes obligations on you. If you are a US citizen, your obligation to file tax returns in the United States continues. If you hold a green card, relinquishing this status has its own specific rules. This page follows these three threads, adding information on the tax regime for expatriates and the reporting of your US accounts, based on official French websites and the IRS.

The day France becomes your tax residence again

French tax residence is based on alternative criteria: the home or principal residence, the center of economic interests, and professional activity (Article 4 B of the French General Tax Code). It is sufficient for one of these criteria to be met (BOI-IR-CHAMP-10). The tax treaty takes precedence over domestic law: if you remain a resident of both countries, Article 4 § 4 of the Franco-American tax treaty establishes the following order of priority: permanent home, center of vital interests, habitual residence, and nationality. Our page on the treaty provides further details on this text.

The year of the return: two declarations the following year

Income earned in the year of your return (N) is declared the following year (N+1). If you had income from French sources before your return, income received from January 1st to the date of your return should be declared on form 2042-NR; income received after your return, whether from French or foreign sources, should be declared on form 2042. Since you had no tax obligations in France during your absence, you declare all income received from the date of your return to December 31st, and you must complete a paper return if this is your first time filing in France.

American citizen: returning does not change the American obligation

American citizens living abroad report their income as if they were residents of the United States (IRS). The safeguard clause of the convention (Article 29, paragraph 2) allows the United States to tax its citizens as if the convention did not exist; it leaves Article 24 on tax credits and Article 18, paragraph 1 on pensions unaffected. Two American mechanisms limit double taxation:

• Exclusion of income earned abroad (Form 2555), for citizens and residents who have their tax home abroad and reside in good faith abroad or are present there for 330 full days in any twelve-month period. 2026 ceiling: 132,900 $ (IR-2025-103). Income still needs to be declared.
• The foreign tax credit (form 1116). No credit is allowed for tax relating to excluded income.

On the French side, Article 24 § 1 b) extends the tax credit to certain U.S.-source income for U.S. citizens residing in France. The IRS also outlines simplified procedures for Americans living outside the United States who certify the absence of deliberate conduct; these procedures are excluded if an audit is already underway.

Green card: exiting US resident status

A green card holder for at least 8 of the last 15 tax years is considered a "long-term resident." If they terminate their residency, the expatriate tax may apply. This tax targets "covered expatriates," defined by one of the following criteria: net worth of at least $2 million at the departure date, average five-year tax liability exceeding an indexed threshold (206,000 $ for 2025), or the absence of a five-year tax compliance certificate. Form 8854 is the expatriate tax return (with a 10,000 $ penalty for failure to file). For a covered expatriate, assets are deemed to have been disposed of the day before departure, with an exclusion of 890,000 $ for 2025. The year of departure is typically a dual-status year (IRS and resident tax status).

The regime of impatriates (article 155 B)

It requires tax residency outside France for the five calendar years preceding the start of employment, and direct recruitment from abroad or intra-group mobility; individuals who come of their own accord are excluded. It applies until December 31 of the eighth calendar year following the start of employment. It exempts the expatriation bonus, the portion of remuneration linked to work abroad, and 50% of certain foreign-source income (investment capital, intellectual property, capital gains from the sale of securities). The real estate wealth tax is limited to assets located in France until December 31 of the fifth year following the establishment of residency. A tax ruling is possible. The official website (updated April 8, 2026) is the starting point; the 30% allowance is not specified here.

US Accounts, Contracts and Securities: 3916 and 3916-bis

Once you are domiciled in France, you must declare, with your 2042 tax return, any bank accounts opened, held, used, or closed abroad (form 3916) and any capitalization contracts or similar investments, including assurance-vie, taken out outside of France (3916-bis). The declaration is made online if the 2042 form is online. The penalty is €1,500 per undeclared account or contract, increased to €10,000 per undeclared bank account if the French government has not concluded an administrative assistance agreement granting access to banking information. A surcharge of 80% of the tax due applies to the amounts held in an undeclared account or contract when these amounts have not been declared for tax purposes; this surcharge replaces the penalty, the amount of which constitutes its minimum (BOI-CF-INF-20-10-50). A U.S. citizen also remains subject to FBAR beyond 10,000 $ in foreign accounts, and to Form 8938, the thresholds for which for taxpayers living abroad are 200,000 $ at year-end or 300,000 $ at some point during the year (single).

US income received in France: tax credit and form 2047

Foreign-source income is declared on form 2047, an annex to form 2042. According to Article 24, paragraph 1(a), the tax credit is equal to the corresponding French tax on most income, and to the US tax paid (up to the limit of the French tax) on dividends and interest. Article 18, paragraph 1, restricts retirement pensions to the state of origin; the effect on a French tax return, particularly for a 401(k) plan or an IRA, is explained in the text.

Exit tax: what the return changes

If you left France subject to exit tax (at least six years of tax residence out of ten, and holding securities whose thresholds are detailed on our exit tax page), form 2074-ETD provides for a tax reduction or refund upon returning to France for tax purposes, provided you still hold the securities. A tax reduction is also granted, provided you still hold the securities, after a period of two years if the total value is less than €2.57 million, and after five years if it exceeds that amount. Our page on exit tax forms details the declarations.

The expatriate tax regime: a numerical example (fictitious profile)

Situation. A fictional French executive returns from Boston and takes up his post in France on September 1, 2026. Recruited directly from abroad, he has not been a resident of France for the previous five calendar years. He receives €24,000 in dividends from foreign sources annually.

Issue. He wants to know the duration of the scheme, the end date of the IFI cap and the portion of his dividends that is exempt.

Strategy. He applies the rules of the official expatriates page, and notes his declaration dates.

Result. The tax regime runs until December 31, 2034, and the limitation of the French wealth tax (IFI) to assets located in France lasts until December 31, 2031. On €24,000 of dividends, the 50% % exemption applies to €12,000, and the remaining €12,000 remains taxable, subject to conditions and the cap on the cumulative exemptions (this example assumes that the cap is not reached, as no remuneration is paid). Income from 2026 is declared in 2027: 243 days (from January 1 to August 31) on form 2042-NR for French-source income only, and 122 days (from September 1 to December 31) on form 2042.

What changes depending on your situation

• Your nationality and US status: citizen, green card holder, or neither.
• The exact date of your return and the nature of your income before and after.
• Your eligibility under Article 155 B depends on your recruitment method.
• Your US accounts and contracts: thresholds and declarations on the French and US sides.
• The five-year rule in Article 23 § 6 of the convention refers to the ISF; its application to the IFI is not established here.
