Overview
France has one of the most favorable treaty positions in this guide for American retirees. Under Article 18 of the US–France treaty, as amended by the 2004 protocol, US Social Security and distributions from US retirement plans paid to a French resident are taxable only in the United States. France formally confirmed this reading in a 2020 ministerial answer to the French Senate. Some sources still say France taxes these payments; they rely on the pre-2004 treaty text or generic OECD rules. The Roth IRA remains the one genuinely open question.
Traditional IRA / 401(k) / Pension Treatment — Settled
Article 18, paragraph 1, as replaced by the 2004 protocol (in force since 2009), provides for exclusive source-country taxation of pension distributions and similar payments from a retirement arrangement established in one country to a resident of the other, whether paid periodically or as a lump sum. The US Treasury's Technical Explanation of the protocol states this directly.
The French government has confirmed it applies the rule this way. In a January 2020 answer to a written question from the French Senate (question no. 13777), the Ministry stated that amounts from US retirement plans, whether paid in a lump sum or periodically, are taxable only in the United States under Article 18(1), and that the list of US plans in Article 18(2) doesn't limit that rule.
How it works on your French return: you still declare the income, and France may include it when calculating the rate on any other French-taxable income. France then grants a tax credit equal to the French tax on those amounts, so the net French tax on them is zero.
Why some sources disagree: sources stating that France taxes US pensions as the country of residence reflect either the original 1994 treaty text or the generic OECD model, not the amended treaty.
One narrow edge case: the treaty refers to payments "in consideration of past employment." Rollovers from a 401(k) fit cleanly. An IRA funded only by personal contributions is a theoretical gray area, though the Ministry's broad wording suggests France doesn't draw that line.
Roth IRA Treatment — Contested
This is the one open question on this page. If a Roth IRA counts as a US retirement arrangement under Article 18, qualified Roth distributions are taxable only in the US, where they're tax-free, and France's credit mechanism cancels any French tax. Several cross-border planners, including Creative Planning, take this position. The French administration's 2020 Senate answer addressed "US retirement plans" generally but didn't name the Roth, and there is no formal French guidance on Roth IRAs specifically. Some advisors therefore recommend declaring Roth distributions on the French return and claiming treaty relief rather than assuming automatic exemption.
The favorable position is strong, but not officially confirmed. A retiree who wants certainty for their own situation can request a rescrit fiscal, a written ruling from the French tax administration that binds it for that taxpayer.
Social Security Treatment — Settled
US Social Security paid to a French resident is taxable only in the United States under Article 18(1). As with retirement plan distributions, you declare it on your French return and France grants a credit equal to the French tax on it, so the net French tax is zero.
The Distinct French Trap: Social Charges (CSG/CRDS)
French social charges on investment income (CSG, CRDS, and related levies) add roughly 17–19% on top of income tax. They don't apply to US retirement plan distributions or Social Security, which are covered by Article 18.
For years, many sources said these charges weren't covered by the treaty and couldn't be credited against US tax. That changed in 2019: the IRS recognized that CSG and CRDS count toward the foreign tax credit under the US–France treaty, and the French administration's official commentary treats them as covered taxes. For US-source dividends and interest, a special treaty rule for US citizens generally gives a French credit that cancels the French tax. Social charges remain a real cost on French-source and other non-US investment income.
Wealth Tax Exposure — Settled
France does not have a comprehensive net-worth wealth tax, but does levy the IFI (Impôt sur la Fortune Immobilière), a tax specifically on real estate holdings above a threshold — narrower than Spain's worldwide wealth tax, but real for anyone holding significant French or global property.
Key Planning Consideration
France's treaty position makes it unusually attractive for retirees drawing down Traditional IRAs and 401(k)s: what's left is the US tax you'd owe anyway, with no French layer on top and no requirement to live in a particular region. The planning questions that remain are the Roth IRA (above), any French-source or non-US investment income, and French inheritance tax, which can matter more than income tax for larger estates.
