US Taxes for Americans Living in France
France is one of Europe's most complex tax environments for US expats. The French tax authority (Direction Générale des Finances Publiques) and the IRS both assert jurisdiction over US citizens residing in France, and France's tax rates rival the highest in the world. The US-France tax treaty is extensive, but a significant additional challenge is France's Impôt sur la Fortune Immobilière (IFI), a wealth tax on real estate holdings that is not creditable against US income tax. Navigating all of this correctly demands expertise.
Local tax authority
The US-France tax treaty (1994, updated 2009) is one of the most comprehensive US bilateral tax treaties. It covers income tax, capital gains, pensions, dividends (15% treaty rate), interest (0%), and royalties (0%). Notably, Article 29 (Limitation on Benefits) is detailed, and the treaty includes special provisions for US social security and French pension portability.
France-specific complexities
- France's top income tax rate of 45% plus 17.2% social charges (prélèvements sociaux), FTC is the dominant strategy
- French Impôt sur la Fortune Immobilière (IFI), real estate wealth tax on holdings above €1.3M, is not creditable against US income tax
- French social charges (CSG/CRDS) creditability as foreign taxes is partially recognized after the Eshel court ruling but remains complex
- France requires residents to report foreign accounts on the annual Cerfa 3916 form, analogous to FBAR
- US-France totalization agreement coordinates Social Security / French pension (retraite) contributions
- French gift and inheritance tax rates are high and can interact with US estate tax on the same assets
What's different about filing from France
French income tax and social charges
France's income tax (impôt sur le revenu) runs up to 45%, but that's only part of the picture. Social charges (prélèvements sociaux), CSG, CRDS, and related levies, add up to 17.2% on investment income and 9.2% on employment income. The total marginal rate for investment income can exceed 62%. The Foreign Tax Credit is virtually always the right tool for US expats in France, and even then, the social charges create complications around creditability, a nuanced area that we navigate carefully.
The IFI (French wealth tax on real estate)
France abolished its general wealth tax (ISF) in 2018, replacing it with the narrower Impôt sur la Fortune Immobilière (IFI), which applies only to net real estate holdings above €1.3 million. US expats who own significant French real estate, directly or through entities, may owe IFI. Critically, IFI is not an income tax and is not creditable against US income tax through the Foreign Tax Credit. It represents a genuine additional cost for property-rich US expats in France.
French pension (retraite) and the totalization agreement
The US-France totalization agreement prevents dual social security taxation. Employees in France generally contribute to the French retraite system rather than US Social Security. For US purposes, French pension income received in retirement is subject to special treaty provisions, often taxable only in France for French residents, or only in the US for US citizens who have returned. The interaction of totalization coverage, future Social Security benefits, and French retraite rights requires long-term planning.

Frequently asked questions about US taxes in France
Should I use FEIE or FTC for my French income?
FTC is almost always the right choice for US expats in France. Between income tax (up to 45%) and social charges (up to 17.2%), French taxes typically far exceed US rates. Using FEIE in France wastes a large amount of available foreign tax credits and triggers the 5-year revocation bar, making it very difficult to switch back if you later move to a lower-tax country.
Are French social charges (CSG/CRDS) creditable against US tax?
Partially, and it depends. After the Eshel v. Commissioner decision, the IRS has agreed that some French social charges may qualify as creditable foreign taxes. Whether CSG/CRDS on your specific income qualifies is fact-dependent. We apply the most favorable supportable position for your situation.
Do I need to report my French bank accounts on FBAR?
Yes. All French financial accounts, BNP Paribas, Société Générale, Crédit Agricole, Boursorama, etc., count toward your FBAR threshold. France also requires French residents to report their foreign accounts on Cerfa 3916 annually, creating overlapping reporting in both directions.
I own French real estate, how does IFI affect my US taxes?
If your net French real estate assets exceed €1.3M, you likely owe IFI to France. This cannot be credited against your US income tax (IFI is not an income tax). IFI is a genuine additional French cost. Rental income from French property must be reported on your US return (Schedule E) with FTC for French taxes paid on that rental income.
