The year you move to or leave France creates two concurrent filing obligations: a partial-year French return and a full-year US return covering the same calendar period. The two returns overlap, tax some of the same income, and must be coordinated carefully to avoid both double taxation and missed relief.
France taxes residents from the date domicile is established, not from January 1. The United States taxes US citizens on worldwide income for the full calendar year, regardless of when they moved. Foreign tax credits and, in some cases, the Foreign Earned Income Exclusion resolve the overlap — but only if applied correctly.
Year of Arrival: What Changes and When
The Start Date
French tax liability begins on the date the first criterion under Art. 4B CGI is satisfied. For most US citizens relocating to France, this is the date they establish a household — often the date of arrival or the date they sign a lease and move in. It is not the date they register with a local authority, open a bank account, or obtain a visa.
The start date is precise. Identifying it correctly matters because:
- Only income from that date onward is reportable on the French return
- The FEIE (if used) is prorated from that date
- FTC claims on the US return cover only French taxes attributable to the post-arrival period
What Is Reportable in France
From the date of arrival through December 31, a French tax resident is liable for French income tax on worldwide income. This includes:
| Income Type | French Treatment |
|---|---|
| Salary from a French employer | Taxable in France; employer withholds via prélèvement à la source |
| Salary from a foreign employer (remote work) | Taxable in France from arrival date; no automatic withholding; acompte installments required |
| French investment income (dividends, interest) | Taxable; subject to PFU (30% total) or progressive barème election |
| Foreign investment income | Taxable in France for the post-arrival period; treaty may limit or allocate taxing rights |
| Foreign pension income | Subject to treaty allocation; the US–France treaty grants exclusive taxation rights to the source state for some pensions |
Income earned before the arrival date is not reportable on the French return, even if received during the French tax year.
Withholding at Source: The Default Rate Problem
France’s prélèvement à la source system withholds income tax monthly for employees and collects quarterly installments (acomptes) from the self-employed. New arrivals with no prior French tax history are assigned a default withholding rate by the DGFiP. This default rate is calculated without knowledge of the individual’s actual income profile and may be significantly too high or too low.
Recommended steps on arrival:
- Create an Espace Particulier account at impots.gouv.fr
- Enter estimated income for the partial year to request a revised withholding rate
- Keep records of all French taxes withheld and paid throughout the year
The annual declaration (filed in spring of the following year) reconciles the actual liability against the amounts withheld. Any shortfall is collected; any excess is refunded.
Filing the First French Return
The first French tax return is filed in spring of the year following arrival, covering the partial year from the date of domicile through December 31. The form is Form 2042, submitted electronically via impots.gouv.fr.
On the form, the taxpayer indicates the date French residency began. The DGFiP applies the progressive barème (or PFU for investment income) to the reported income for the partial year.
Practice note: France requires online filing for virtually all taxpayers. First-time filers must create an Espace Particulier account. The process can take several weeks if identity verification is required. Begin this process promptly after arriving.
US Return Coordination in the Year of Arrival
The US return covers the full calendar year. All worldwide income — pre-arrival and post-arrival — is reported on Form 1040. The challenge is ensuring that post-arrival income is not taxed twice.
Foreign Tax Credit (Form 1116)
French income taxes paid on post-arrival income are creditable on the US return via Form 1116. The credit offsets US tax dollar-for-dollar, subject to the FTC limitation:
- Wages and active income taxed in France: general category basket
- Investment income subject to the PFU: passive category basket (12.8% income tax component only; the 17.2% social charges component is a separate creditability question)
Only French taxes attributable to post-arrival income are creditable. French taxes attributable to pre-arrival income (if any French-source income was received before arrival) are analyzed separately.
Foreign Earned Income Exclusion (Form 2555)
The FEIE is available for the qualifying portion of the year, but the exclusion must be prorated. A US citizen who arrives in France in April and qualifies for the full remainder of the year can exclude only the portion of the $130,000 limit (2025) that corresponds to the qualifying days.
Proration formula: Maximum exclusion × (qualifying days ÷ 365)
For a taxpayer who arrives April 1 and qualifies through December 31 (275 days), the 2025 proration is approximately $97,945.
Critical planning note: The FEIE and FTC are mutually exclusive on the same income. French income taxes paid on FEIE-excluded income are not creditable on the US return. For most US persons in France, the FTC alone eliminates US tax on French-source income, making the FEIE unnecessary and potentially counterproductive. The decision should be modeled before filing.
Year of Departure: What Changes and When
The End Date
French income tax liability ends on the date French tax domicile ceases. This is typically the day the individual leaves France and establishes domicile elsewhere. As with the arrival date, precision matters — the partial-year French return covers income only through that date.
Before fixing the departure date, exit tax exposure under Art. 167 bis CGI must be evaluated. The exit tax is assessed as of the departure date on unrealized gains in qualifying financial assets. Once the taxpayer departs, pre-departure restructuring options are closed.
The Partial-Year Departure Return
The departure-year French return covers income from January 1 through the date of departure. The taxpayer files Form 2042 in the spring following the departure year, indicating the departure date.
Administrative step: Departing residents must notify the DGFiP of their change of address and change to non-resident status. Failure to do so can result in continued assessment of French income tax as a resident.
Continued French Exposure After Departure
Departure from France does not eliminate all French tax obligations. Non-residents with French-source income remain subject to French income tax on:
| Income Type | Post-Departure Treatment |
|---|---|
| Salary for work physically performed in France | Taxable in France |
| Rental income from French property | Taxable in France |
| French-source dividends | Taxable at treaty withholding rate (generally 15% under the US–France treaty) |
| Capital gains on French real estate | Taxable in France |
| French pension income | Subject to treaty allocation (exclusive source-state taxation under Art. 18(1)) |
Non-residents are subject to minimum flat rates under Art. 197A CGI: 20% on income up to approximately €29,579 (2025 threshold) and 30% on income above that threshold. Non-residents may elect the taux moyen (average rate) option if their worldwide effective rate, calculated using the progressive barème on all worldwide income, is lower than the applicable minimum. This election requires disclosing worldwide income to the DGFiP on the annual return.
US Return Coordination in the Year of Departure
The US return again covers the full calendar year. French taxes paid for the partial-year period of French residency are creditable on Form 1116. French withholding taxes on French-source income received after departure are also generally creditable.
Technical Reference
Governing statutes: Art. 4B CGI (residency start and end date); Art. 167 bis CGI (exit tax, assessed at departure date); Art. 197 and 197A CGI (progressive barème and non-resident minimum rates).
Form references:
- Form 2042: French annual income tax declaration; partial-year version for arrivals and departures
- Form 1116: Foreign Tax Credit; credits French income tax against US liability; basket allocation required (general category for wages, passive for most investment income)
- Form 2555: Foreign Earned Income Exclusion; prorated for partial qualifying year; mutually exclusive with FTC on excluded income
- Schedule SE: Self-employment tax; not eliminated by the FEIE; totalization agreement may exempt if coverage is in France
Treaty reference: Art. 18(1) of the US–France treaty grants exclusive source-state taxing rights for social security and pension income; relevant for both arriving and departing taxpayers receiving French or US pension income.
Key coordination issues:
- FTC timing: French prélèvement à la source withheld throughout the year is creditable in the year withheld (cash method). Ensure the US tax year in which the credit is claimed matches the French payment year.
- FEIE revocation: If a taxpayer previously claimed FEIE for a pre-France foreign assignment and revokes it to switch to FTC upon arrival in France, the 5-year lockout against re-election applies. Revocation requires a statement attached to the return for the first year the exclusion is not claimed.
- Proration of housing exclusion: If the FEIE is used, the housing exclusion base amount ($39,000 for 2025; $37,950 for 2024) is also prorated by qualifying days. The location-specific limit for Paris is published in the annual IRS Notice (Notice 2025-16 for 2025).
Frequently Asked Questions
When exactly does French tax liability begin in my year of arrival?
French tax liability begins on the date French tax domicile is established under Art. 4B CGI, not on January 1. For most US citizens relocating to France, this is the date they establish a household (the foyer criterion). Income earned before that date is generally not subject to French income tax, though French-source income may be subject to withholding.
Do I report my full year’s income to France or only the income earned after I arrived?
Only income from the date of arrival through December 31. The partial-year French return covers worldwide income for that period, subject to treaty allocation of taxing rights. Income earned before French domicile was established is not reportable on the French return.
How does the FEIE work if I moved to France mid-year?
Yes, the FEIE is available for the qualifying portion of the year, but the exclusion is prorated. The maximum exclusion ($126,500 for 2024; $130,000 for 2025) is multiplied by the number of qualifying days divided by 365. You must meet either the bona fide residence or physical presence test for the days claimed.
How do I avoid being taxed on the same income by both France and the US in my year of arrival?
The Foreign Tax Credit (Form 1116) is the primary mechanism. French income taxes paid on post-arrival income are creditable against US tax liability on a dollar-for-dollar basis, subject to the FTC limitation. The same income appears on both returns, but the credit prevents double taxation in most cases.
What French return do I file for my first partial year in France?
Form 2042, the standard French annual income tax declaration, filed in the spring following your year of arrival. You indicate that the return covers a partial year. The return is filed electronically via impots.gouv.fr.
What is prélèvement à la source and how does it affect me in my year of arrival?
Prélèvement à la source is France’s withholding-at-source system, in effect since 2019. New arrivals with no prior French tax history are assigned a default withholding rate, which may not reflect actual liability. Creating an Espace Particulier account at impots.gouv.fr and entering estimated income helps establish a more accurate rate. The annual declaration reconciles actual liability against amounts withheld.
When does French tax liability end in the year I leave France?
French income tax liability ends on the date French tax domicile ceases, typically the date of departure. The individual files a partial-year French return for income through that date. French-source income received after departure may still be taxable in France as non-resident income.
Do I owe French tax on income I earn after leaving France?
Yes, on French-source income. Non-residents pay French income tax on income sourced to France, including employment income for work performed in France, rental income from French property, and certain French-source investment income. Worldwide income from non-French sources after the departure date is not subject to French income tax.
