US-France Taxes for American Retirees: The Complete Guide

France has a reputation as one of the most heavily taxed countries in the developed world, and for high earners that reputation is mostly earned. So it surprises a lot of Americans to learn that, for a retiree living on Social Security, a pension, and withdrawals from retirement accounts, the French system is usually favorable. The reason is a tax treaty between the United States and France that treats American retirement income unusually well — though, as we cover below, one French health contribution sits outside that treaty and deserves a look if you plan to live mostly off investments.

This guide explains how that works in plain terms: when France starts to consider you a tax resident, what the treaty protects and what it doesn't, how each kind of retirement income is actually taxed, what you still owe the United States, and the parts of the French system that catch Americans off guard, including the wealth tax, social charges, and inheritance rules. It answers the questions people planning a move to France actually ask. It is not advice on your specific situation, and the last section explains who is qualified to give you that.

The two tax systems you'll live under

Once you retire to France, two tax systems apply to you at the same time.

The United States taxes its citizens on worldwide income for life, regardless of where they live. You will keep filing a US federal return every year for as long as you hold US citizenship, no matter how long you have been gone. The treaty does not change this. The clause that preserves it is called the saving clause, and its effect is that the US can still tax you even when France considers you a resident.

France taxes its residents on their worldwide income. So once you become a French tax resident, France also expects an annual return that reports everything you earn, everywhere.

The treaty exists to keep these two systems from taxing the same income twice. It does that well for retirees, but only if both returns are prepared correctly and the treaty positions are actually claimed. The rest of this guide is about how that plays out.

When does France consider you a tax resident?

This matters because residency is what pulls your worldwide income into the French system. People assume it comes down to spending 183 days in France. It does not. Under Article 4 B of the French tax code (the Code général des impôts), you are a French tax resident if you meet any one of four tests. Meeting a single one is enough, and it makes you resident for the whole calendar year.

The four tests are:

Your home (foyer) is in France. Your habitual, settled home, the place your personal and family life is based. For a couple who moves to France together, this is usually met from the day you set up your household, often the day you arrive.
Your main professional activity is in France. Where you actively work, whether employed or self-employed. This test is about your job.
Your principal place of stay is in France. This is the 183-day idea. It only becomes the deciding test when you don't have a settled home anywhere.
The center of your economic interests is in France. Where your main investments and assets sit, and where most of your income comes from. This test is about your money, not your work.

For a retiree, only two of these usually come into play. The professional-activity test rarely applies, since you're not working. The economic-interests test tends to point away from France rather than toward it, because your assets and income are still mostly in the US. That leaves the foyer test, which almost always makes you resident the moment you set up home in France, with the 183-day stay as a backstop for people who have no settled home anywhere.

So if you're moving to France to live, assume you become a French tax resident on arrival. Residency is a factual question the French tax authority decides, not a box you check. And if you split time between two countries, the treaty has its own tie-breaker rules to settle which one treats you as resident.

What the US-France tax treaty actually is

When this guide refers to "the treaty," it means the Convention between the United States and France for the avoidance of double taxation with respect to taxes on income and capital, signed on August 31, 1994, in force since December 30, 1995, and amended by protocols in 2004 and 2009.

There is also a second, separate treaty that covers inheritance: the US-France estate and gift tax convention, signed November 24, 1978, and amended by a 2004 protocol. People often assume the income treaty handles everything. It doesn't. Estates are governed by their own agreement, which is covered in the inheritance section below.

The income treaty assigns each type of income to one country or the other, or splits the taxing rights and provides a credit so the same euro isn't taxed twice. For American retirees, the relevant articles are Article 18 (pensions and social security), Article 24 (relief from double taxation, which covers most US investment income), and Article 29 (the saving clause). Here is what they mean for each kind of income you're likely to have.

How your retirement income is taxed, type by type

The picture below is for the common case: a US citizen who is a French tax resident. One theme runs through all of it. Even income that France does not tax must still be reported on your French return, because France adds it to your total to work out the rate it applies to whatever income it does tax. Tax professionals call this the taux effectif (effective rate). "France won't tax this" is not the same as "France doesn't need to see it."

The short answer: no, France does not tax it. Under Article 18 of the treaty, US Social Security paid to a French resident is taxable only in the United States. You still list it on your French return so France can work out your effective rate, but France charges no tax on it.

The United States taxes your Social Security exactly as it would if you'd never left: depending on your total income, up to 85% of your Social Security benefits can be subject to US federal income tax. Moving to France doesn't raise that, and it doesn't stack a French tax on top. (If you want the technical reason this holds up: the saving clause described earlier normally lets the US tax its own citizens as if the treaty didn't exist, but Article 18 is one of the specific provisions carved out of it, so this protection survives.)

How are my pension, IRA, 401(k), and annuity distributions taxed?

The short answer: the US keeps the main right to tax them, and France does not tax them on top. For US employer plans, private pensions, 401(k)s, and 403(b)s, Article 18 assigns the distributions to the country they come from, the US, and France relieves them, exempting the income and counting it only toward your effective rate. In practice these are taxed under US rules, at ordinary US rates, with France taking nothing on the distributions themselves.

IRAs reach the same result by a slightly different route. Because an IRA is individually funded rather than tied to past employment, practitioners don't all classify it the same way under the treaty. But for a US citizen the outcome matches the employer plans: France applies a tax credit equal to the French tax that would otherwise be due, which cancels it, so the distribution is not taxed in France. You still report it on your French return and it counts toward your effective rate, but France collects nothing on it.

Either way, this is a big part of why France works for American retirees: the income most retirees actually live on lands under US tax rules rather than stacked on top of France's higher ones.

Will France tax my US dividends, interest, and other investment income?

The short answer: for a US citizen, US-source dividends and interest are not taxed by France at all. Under Article 24, France grants a tax credit equal to the French tax that would otherwise be due on this US-source income. Because the credit equals the French tax, it cancels it completely, not just the income tax, but the CSG and CRDS social charges too. For income tax and those social charges, the result is full neutrality: this income is taxed only by the US. (One separate French health contribution can still reach this income regardless of the treaty; it has its own section below.)

There is one practical catch that matters. For the relief to be applied correctly, your French return has to include a specific declaration (a mention expresse) claiming it. The French tax administration frequently gets this provision wrong, so this is exactly the kind of thing a specialist who knows the treaty makes sure is handled right. You still report the income in France; it just has to be done properly so the credit actually lands.

How are my capital gains taxed if I sell US investments after moving?

The short answer: for a US citizen, gains on the sale of US securities are generally not taxed by France, the same way dividends aren't. When you sell US-source securities (stocks, ETFs, funds) as a US citizen, the Article 24 credit equals the French tax, so France collects nothing, just as with dividends and interest. The same point about claiming it correctly on the French return applies.

Where this changes is for income that isn't a clean US-source securities gain. Employer equity such as RSUs is treated differently, because part of that gain is really compensation tied to where you worked. And gains on non-US-source assets fall outside this relief and can be taxed in France at the flat rate of 31.4% (the prélèvement forfaitaire unique). So the rule of thumb is: ordinary US-source investment gains are protected, but anything involving employer equity or non-US assets needs a specialist to look at it before you sell.

How are Roth IRAs treated? Do Roth withdrawals stay tax-free?

The short answer: report it in France, but it isn't taxed there. Qualified Roth distributions are tax-free under US law, and they are not taxed in France either. France has no domestic Roth equivalent, which once made the treatment look uncertain, but the established position now is that a qualified Roth withdrawal is declared on your French return and not taxed. The result for most retirees is that a qualified Roth stays tax-free on both sides, which makes it an unusually powerful account to carry into a French retirement. As with the rest, report it correctly so it's treated the right way.

Can I keep my US brokerage and retirement accounts?

The short answer: yes, and you generally should, and what you hold inside them matters. Keeping your money in US accounts and US-domiciled investments is usually the right move, for two separate reasons that point the same way.

First, the US side. Moving into French or European investment funds creates a serious US tax problem: under the US "PFIC" rules, most non-US mutual funds and ETFs are taxed punitively for US citizens, with onerous reporting.

Second, the French side. The treaty relief that keeps your investment gains out of French tax depends on those gains being US-source. Gains on US-source funds are protected, as described above, while gains on non-US funds fall outside that relief, and France can tax them. So holding US-domiciled funds rather than local ones keeps your gains away from French tax as well as out of the US PFIC trap.

One practical wrinkle to plan for: some US brokerages restrict or even close accounts once you have a non-US address, so confirm your broker's policy before you move and consider one that serves Americans abroad. This is a place where good cross-border advice pays for itself.

What about my US home or other US real estate?

The short answer: rental income is taxed in the US, but a gain when you sell can produce a French surprise, with one important exception. Rental income from US property is taxable in the US, and France relieves it through the effective-rate mechanism.

Capital gains on US real estate need more care, and this is where people get caught out. If you sell a US property that is not your main home while you are a French tax resident, you must declare the gain in France, and the French credit equals the tax you actually paid in the US, not the full French tax. If your US tax on the sale was low, France can still tax the difference, which is a common and unwelcome surprise. This is very different from US securities, where the credit cancels the French tax entirely.

The important exception: if you sell the main home you owned before moving, and you sell it within about a year of arriving in France, the gain is fully exempt in France. So the timing of selling your US home around your move can matter a great deal, and it is worth planning before you list it.

For the French wealth tax, your US home also gets a meaningful break for new arrivals, explained in the next section.

The French wealth tax (IFI)

France has a wealth tax, but since 2018 it applies only to real estate, not to financial assets. It is called the Impôt sur la Fortune Immobilière (IFI), and it applies when your household's net taxable real estate is worth more than €1.3 million on January 1. The word net matters here: any outstanding mortgage debt on a property is deducted, so only your net equity counts toward the threshold. It is an annual tax, charged every year on a progressive scale that tops out at 1.5%, not a one-time levy.

Two points matter for retirees:

It's real estate only. Your IRAs, brokerage accounts, and cash don't count. Many retirees never come near the threshold.
New arrivals get a five-year break on foreign property. This exemption applies only if you were not a French tax resident during the five calendar years before the year you moved. If you qualify, your real estate located outside France (your US home, for instance) is excluded from the IFI base until the end of your fifth year of residency. During that window only French real estate counts toward the €1.3 million threshold. After it, your worldwide real estate counts.

Beyond income tax, France levies social charges on many kinds of income. The two main ones are the CSG (contribution sociale généralisée, the general social contribution) and the CRDS (contribution au remboursement de la dette sociale, which funds repayment of France's social-security debt). For retirees the treatment is nuanced and depends on your situation, so treat this as the area most worth confirming with a professional.

In general terms: the US-source income that the treaty protects, your Social Security, your pension and retirement-account distributions, and your US-source investment income, is not hit with these French social charges. For a US citizen, the same treaty credit that cancels the French income tax on US-source dividends, interest, and securities gains cancels the CSG and CRDS on them as well. Where these social charges can apply is on French-source or other non-US investment income, at rates up to 18.6%.

There is, however, a separate French levy that the treaty does not relieve and that can reach your US investment income directly. It is common enough among retirees that it gets its own section next.

The PUMa health contribution (the "taxe PUMa")

There is one French charge that can reach income the treaty otherwise protects, and it catches a lot of American retirees off guard. Once you are covered by French public health insurance through residence, under the PUMa system, France can levy a health contribution called the cotisation subsidiaire maladie, informally the "taxe PUMa," on your investment income. Despite the nickname, it isn't legally a tax at all: the French courts have consistently treated it as a social-security contribution — the legal counterpart of your health coverage — and it's assessed by URSSAF, France's social-security collection agency, not by the income-tax authority.

Two things determine how much it matters for you.

First, whether it touches you at all usually comes down to pension income. The law exempts any household where you — or your spouse — received a retirement pension during the year, and the text doesn't say the pension has to be French. In practice, URSSAF has generally treated Americans drawing Social Security, a US pension, or regular retirement-account distributions as exempt on that basis. That practice hasn't yet been confirmed by a court ruling, though, and URSSAF's own written guidance is stricter about non-European pensions — so exemption is something to confirm with your advisor, not to assume. The household most clearly in scope is one living mainly off a portfolio with no pension income yet: say, retired at 58, drawing down a brokerage account, and not claiming Social Security until later.

Second, the treaty does not relieve it. The relief that makes your US-source dividends, interest, and gains free of French income tax and of CSG/CRDS does not extend to this contribution. Your US investment income can be free of French income tax and social charges and still be caught here.

Who it actually hits comes down to two thresholds. It applies to a French tax resident whose earned income taxable in France is below about €9,600 and whose worldwide investment income runs above about €24,000, and it is charged at 6.5% on the investment income above that level. (Those are the 2026 figures; both thresholds track the French social-security ceiling and shift a little each year.) Most retirees have little or no French earned income, so the deciding factor is usually the size of your portfolio income, and a couple living off a US portfolio with no pension income can land squarely inside it.

Three softeners are worth knowing. The base is capped at eight times the social-security ceiling — about €384,000 of investment income in 2026 — so the charge cannot grow without limit. The test is more forgiving for couples than it first sounds: one spouse drawing a pension, or earning above the €9,600 floor, exempts both of you, and when both spouses are assessed, the investment income is split between them and each gets their own ~€24,000 allowance. And the bill arrives in arrears — URSSAF sends the notice each November for the previous year's income — so a household that knows its position never meets it as a surprise.

This is one of the clearest reasons the French-side advice matters as much as the US-side. The contribution isn't in the treaty, it's easy to miss, and for a retiree with a sizable portfolio it can be a real yearly cost. In practice URSSAF assesses first, using the income on your French return, and you contest afterward — by a written réclamation, with no guaranteed outcome — and application is known to vary between regional offices. A cross-border specialist can tell you whether it applies to you and roughly what it would come to, well before any notice arrives.

One more development to have on your radar, as of July 2026: a law passed in December 2025 adds a separate, flat annual participation for residents who are covered by PUMa but exempt from French social contributions under an international agreement — a description aimed squarely at Americans on visitor visas. The amount is still to be set by decree, and until that decree is published nothing is owed. Early signals from the parliamentary debates suggest it will be modest compared with the contribution described above. It's exactly the kind of moving rule worth having someone track for you — the number will be known the week the decree lands.

Inheritance and estate planning

This is where Americans get the biggest surprises, and it is governed by the separate 1978 estate and gift treaty, not the income treaty.

Two things to know. First, France has forced heirship (the réserve héréditaire): a fixed share of your estate is reserved by law for your children. By default this can override what a US will says, but it is not as automatic as many people assume. Under the EU Succession Regulation, commonly called Brussels IV, a US national resident in France can state in their will that the law of their nationality should govern their succession, which can displace French forced heirship. There is an important catch: a 2021 French law lets children who are cut out under the chosen foreign law claim compensation out of assets located in France, up to the share they would have received under French rules. So the election changes the picture significantly, but it does not necessarily free your French property from forced heirship, and it only works when it is set up properly in a valid will. Second, France does not cleanly recognize US trusts, so a revocable living trust that works perfectly in the US can behave very differently, and create reporting complications, once French assets or heirs are involved.

On the tax side, French inheritance tax (droits de succession) is paid by the heir on their share, and the 1978 treaty uses situs rules and credits to prevent the same assets being taxed twice. A US person who inherits more than $100,000 from a French estate generally must file IRS Form 3520, even if no US tax is due. Estate planning across the two countries is specialist work. It usually involves a French notaire (the public officer who handles successions in France) working with a cross-border estate advisor, which can be a French tax lawyer (avocat fiscaliste) or a US estate attorney with French experience. What matters is that someone on the team genuinely understands both legal systems.

Two French products that often backfire for US citizens

Once you're settled in France, you'll likely be offered two popular French planning products. Both make sense for French nationals and are genuinely problematic for Americans.

Assurance vie. This is the cornerstone of French savings and estate planning, a tax-advantaged investment wrapper that most French residents own. For a US citizen it's a trap. The US does not recognize its tax-deferred status, the funds inside it are usually foreign mutual funds that trigger the punitive PFIC rules described earlier, and it can carry heavy US reporting on top. It is one of the first things retirees get pitched in France, and it should not be bought without cross-border advice.
SCI (société civile immobilière). This is a French company widely used to own property and pass it to heirs, and for French families it's a useful tool. For US citizens, holding your home in an SCI can pull you into onerous US foreign-entity reporting (forms such as the 5471 or 8858), entity-classification questions, and real ongoing compliance cost. An SCI is occasionally still the right answer for an American, but only after a US-aware advisor has looked at it, never as a default.

What you still owe the United States

The treaty does not reduce your US filing obligations. As a US citizen in France you generally still:

File a US federal income tax return (Form 1040) every year, reporting worldwide income.
Report your foreign financial accounts. If your non-US accounts together exceed $10,000 at any point in the year, you file an FBAR (FinCEN Form 114). Separately, above higher thresholds, you file IRS Form 8938 under FATCA. These are reporting forms, not extra taxes, but the penalties for missing them are severe, and an ordinary French checking account can trigger them.
Claim treaty benefits and credits correctly, which can involve Form 8833 to take a treaty position and Form 1116 for foreign tax credits, so that income taxed in France isn't taxed again by the US.

Don't forget your former US state

Leaving the country does not automatically end your state tax residency, and some states are aggressive about this. California, New York, and a few others are known as "sticky" states. They keep taxing you as a resident until you genuinely change your domicile, meaning the permanent home you intend to return to.

For retirees this is a trap, because California's well-known "546-day safe harbor" only applies to people abroad under an employment contract. It does not cover retirees. To stop being a California resident, a retiree generally has to change domicile by severing ties: the state looks at where your home, driver's license, vehicle registration, voter registration, bank accounts, and doctors are. A clean approach many people use is to establish residency in a state with no income tax (Florida, Texas, Nevada) before leaving the US, which creates a clearer break.

There is one firm federal protection worth knowing. Under US federal law, a state cannot tax the IRA, 401(k), or pension distributions of someone who is no longer a resident of that state, no matter how aggressively the state tries to hold onto you. So even with a sticky state, your retirement-account income is shielded once you have genuinely established non-residency, and the state's reach is limited to income actually sourced there, not your retirement distributions or investment income.

How the French tax system works, briefly

A few basics, since you'll be filing inside it.

Who runs it. Income tax is administered by the Direction Générale des Finances Publiques (DGFiP), and returns are filed online at impots.gouv.fr, where every resident has a personal account. If you use a professional, they prepare the return and can either file it for you under a mandate or hand it back for you to submit through your own account. Either way, the account and the ultimate responsibility for what's filed stay with you.
The tax. Personal income tax (Impôt sur le Revenu) is progressive, currently running from 0% to 45%. As an approximate guide for recent years, the brackets per "part" of the household run roughly: 0% up to about €11,500, 11% to about €29,300, 30% to about €83,800, 41% to about €180,000, and 45% above that. These thresholds are indexed every year, so check the current figures. One thing to keep in mind: these brackets only bite on income France actually taxes. As explained above, the treaty removes most US retirement income before you ever reach this table, so for many retirees the income running through it is small or zero.
Households, not individuals. France taxes the household (the foyer fiscal). Married couples and civil partners file jointly by default. A "civil partner" here means a couple bound by a PACS (pacte civil de solidarité), France's registered-partnership status that sits between cohabitation and marriage and carries most of the same tax treatment. The household's total income is divided across "parts" (the quotient familial) before the brackets apply, which often helps couples.
How it's collected. Since 2019, France collects income tax through the year rather than in one annual bill, a system called prélèvement à la source. Where there is no French payer to withhold from, such as your US pensions, France instead takes monthly or quarterly installments by direct debit, based on your last return, and squares up when you file. For most American retirees this is close to a non-issue: where the treaty leaves France little or nothing to tax, there is little or nothing to collect. It only ever changes the timing of any French tax, never the amount.
When you file. The annual return (déclaration de revenus) is filed in spring and reports the prior year's income. Online deadlines fall roughly between late May and early June and vary by département; the paper deadline is earlier, around mid-to-late May.
Investment income. French-source dividends, interest, and gains are generally taxed at a flat 31.4% (the prélèvement forfaitaire unique), or you can elect the progressive scale if it's lower. For US retirees, recall that the treaty relieves US-source investment income from French tax in the first place, so this flat rate mainly bites on any genuinely French-source investment income you have.

Who can actually do your taxes?

The professional titles don't map across the two countries, and using the wrong one is a common, expensive mistake. A quick guide:

US CPA (Certified Public Accountant): a US credential. A CPA prepares your US return and US filings. Some CPAs specialize in Americans abroad and handle things like the FBAR and FATCA forms well, but knowing the US expat side is not the same as knowing France. Most won't prepare a French return, and most don't know the treaty's nuances. They can do the US half correctly and leave the French half, and the coordination between the two, undone.
Expert-comptable: the French chartered accountant. Many prepare individual returns and advise residents, including expatriates, on income tax, the IFI wealth tax, and succession. A capable expert-comptable can absolutely handle your French side. The title is not the issue. The issue is whether the person also understands US taxation and the treaty, which most don't.
Avocat fiscaliste: a French tax lawyer. This is the profession for French tax advice, planning, and disputes, particularly anything complex or contested.

In France you are not required to use any of them. Most French residents simply self-file online. The question is not whether you're allowed to file yourself, it's whether your situation is simple enough that you should.

For a cross-border retiree, the real requirement is that someone covers both sides and the treaty between them. A handful of firms genuinely do both French and US tax under one roof, with real command of the treaty. They are rare, and they cost more than a local accountant. For income and accounts spread across two countries, that premium is usually justified: it reflects how few people can do this work properly, and a single coordinated filing is exactly what prevents the expensive gaps. The workable alternative is a US preparer and a French preparer who actively coordinate. The one to avoid is a US accountant and a French accountant who never speak, each filing as if the other doesn't exist, because the costly errors happen in the gap between the two returns.

So how much will you actually pay?

Honestly, it depends entirely on your mix of income and assets, and anyone who gives you a number without seeing your situation is guessing. But the shape is encouraging, and it's the opposite of France's high-tax reputation.

Because the treaty routes most US retirement income, Social Security, pensions, IRA and 401(k) withdrawals, and US investment income, to US taxation, a typical American retiree often finds that France taxes little or none of it directly. You generally pay US tax on that income at US rates, and France's role is mostly to include it for the effective-rate calculation and to tax any genuinely French-source income you have. For many retirees the combined result is comparable to, or lower than, what they paid at home, and in some cases lower than staying in a high-tax US state would have been.

The flip side is that the protections only work if the returns are done right: residency assessed correctly, treaty positions claimed (with the mention expresse where it's needed), US reporting kept up, and the French and US filings coordinated. The one charge to keep in view alongside all of this is the PUMa health contribution covered above — the piece of the French system most likely to surprise a household living off a large portfolio, and also the one good advice sees coming a year ahead. That is the real work, and it's why getting the right help matters more than any single rule in this guide.
