US Expats in France: Complete Financial Planning Guide (2026)

France is home to more than 100,000 US citizens — in Paris, Lyon, Bordeaux, and the tech corridors of Sophia Antipolis. For Americans, France is also one of the more complex financial environments in the world: high income tax rates (up to 45%), broad social charges on both earned and investment income, an IFI wealth tax on French real estate, and an investment culture built around products — the PEA and assurance-vie — that create reporting landmines for US citizens. Getting the Foreign Tax Credit vs FEIE decision wrong, stumbling into a PFIC inside a PEA, or opening an assurance-vie without understanding the Form 3520 exposure can add years of costly corrections.

1. The Core Tax Decision: Foreign Tax Credit Wins in France for Most Earners

US citizens abroad must choose between two mechanisms to avoid double-taxation on earned income:

• Foreign Earned Income Exclusion (FEIE, Form 2555) — excludes up to $132,900 of foreign earned income from US gross income in 2026.¹
• Foreign Tax Credit (FTC, Form 1116) — credits French income taxes (and creditable social charges) paid directly against your US tax liability, dollar for dollar.²

French Income Tax Rates (2026 Tax Return, Applicable to 2025 Income)

France uses a progressive bracket system (barème) with five tranches, applied per quotient familial share. For a single person (1 share), the thresholds apply directly to individual taxable income. For a couple filing jointly (2 shares), all thresholds double. The 2026 Loi de Finances indexed thresholds upward by 0.9% for inflation.³

A US citizen earning €75,000 (~$82,500 at 2026 rates) in Paris as a single filer pays approximately €14,000 in French income tax — an effective rate near 19% — before social charges. Adding creditable CSG/CRDS of roughly €7,275 (9.7% on wages), total creditable French taxes are approximately €21,275 (~$23,400). US federal tax on $82,500 of ordinary income (single filer, after standard deduction) is approximately $11,500. The FTC of $23,400 fully eliminates the US liability, with over $11,000 of excess credits to carry forward 10 years.

By contrast, FEIE would exclude $82,500 from US gross income — but you'd still owe all French taxes, lose IRA contribution eligibility for excluded income, pay US self-employment tax in full on the excluded income under §1402(a)(8), and be locked into the FEIE election for five years after revocation. Use our FEIE vs FTC calculator to model your specific income level.

The main scenario where FEIE might be considered: very low earners in France whose French tax is minimal and who have significant unearned income they want to keep in the US tax base. Even then, the loss of IRA eligibility and SE tax exposure usually tip the analysis toward FTC. For mid-to-high earners (income in the 30% or 41% French bracket), FTC wins unambiguously.

2. French Social Charges: CSG, CRDS, and the New CFA

France levies social charges on top of income tax. For US citizens, these are critical because they are creditable as foreign taxes for US FTC purposes — confirmed by the IRS in 2019 via diplomatic communication with France, reversing earlier uncertainty.⁴

Social Charges on Earned Income (Wages, Self-Employment)

Employees in France pay:

• CSG (Contribution Sociale Généralisée): 9.2% on 98.25% of wages (of which 6.8% is partially deductible for French income tax purposes)
• CRDS (Contribution au Remboursement de la Dette Sociale): 0.5%
• Combined employee-side social charges: approximately 9.7% on gross wages

These are entirely creditable on Form 1116 since the 2019 IRS-France agreement confirmed they are not social security taxes covered by the US-France Totalization Agreement — and therefore qualify as income taxes for FTC purposes.

Social Charges and PFU on Capital Income

French-source investment income (dividends, interest, capital gains) is subject to the prélèvement forfaitaire unique (PFU) — a flat tax of 31.4% in 2026. This is composed of:⁵

• Income tax component: 12.8%
• CSG: 10.6% (raised from 9.2% by the 2026 Finance Act's new contribution financière pour l'autonomie)
• CRDS: 0.5%
• Solidarity contributions: 7.5%

For US citizens, the creditable portion (CSG + CRDS + income tax) typically exceeds the US tax on the same passive income — again generating excess FTC credits rather than US tax owed. Taxpayers may alternatively opt for the progressive bracket rates (barème) on capital income if that produces a lower combined rate; specialist guidance is needed to optimize.

3. The PEA (Plan d'Épargne en Actions): A Potential PFIC Trap

The PEA is France's flagship equity savings account, offering attractive French tax treatment: no French income or capital gains tax on gains if the account is held for at least five years, with a contribution cap of €150,000 (classic PEA) or €225,000 (PEA-PME for small-cap investments). For French taxpayers, it is an excellent tool.

For US citizens, the picture is more complicated:

• PFIC risk from pooled funds: If you hold French or European mutual funds, OEICs, SICAV, or ETFs domiciled in France or elsewhere in the EU inside a PEA, those holdings are almost certainly Passive Foreign Investment Companies (PFICs) under IRC §1297. Holding them without a QEF or mark-to-market election triggers the §1291 excess-distribution regime — taxed at the highest ordinary rate plus compound interest back to when the investment began appreciating. See our PFIC tax impact calculator for how severe this penalty compounds over a decade.
• Individual stocks avoid PFIC: If you limit PEA holdings to individual French or European listed equities (no pooled vehicles), you avoid PFIC classification. The PEA does allow individual stock holdings, and this is theoretically workable — but requires active management and discipline to never buy a fund within the account.
• French tax deferral not recognized by the US: Growth inside the PEA is not tax-deferred for US purposes. Dividends and realized gains are taxable in the US in the year earned regardless of the French wrapper.
• Reporting required: The PEA is a foreign financial account that must be reported on FBAR (FinCEN 114) if aggregate foreign accounts exceed $10,000, and on Form 8938 above the applicable FATCA threshold for taxpayers living abroad ($200,000 single / $400,000 MFJ at year-end, or $300K / $600K at any point during the year).

Most US-aware advisors recommend that US citizens in France hold their equity investments in a taxable brokerage account (FBAR-reportable) using US-domiciled ETFs, which can be acquired through US brokerages and have no PFIC issues. The tax efficiency lost by forgoing the PEA wrapper is far smaller than the potential §1291 penalty from accidental PFIC exposure.

4. Assurance-Vie: France's Favorite Savings Vehicle — Largely Impractical for US Citizens

The assurance-vie is the most popular long-term savings vehicle in France. It is structured as a life insurance wrapper around investment sub-accounts (unités de compte), offering French tax deferral, reduced rates after eight years of holding, and favorable inheritance treatment outside the French estate. Over €1.8 trillion in assets are held in French assurance-vie contracts.

For US citizens, the assurance-vie presents serious compliance obstacles:

• Foreign grantor trust classification: If the contract allows the policyholder to direct investments and retains beneficial ownership characteristics, the IRS may classify it as a foreign grantor trust under IRC §679 or §671-677 — requiring annual filing of Form 3520 and Form 3520-A (failure penalty: 35% of the gross value of any contribution or distribution). This is the most common US tax characterization of assurance-vie.
• PFIC exposure: Sub-accounts (unités de compte) typically hold French or European pooled funds — PFICs. If the grantor trust classification doesn't apply, the PFIC rules apply to the underlying holdings, requiring Form 8621 filings and potentially triggering §1291 excess-distribution treatment on any gains.
• No US tax deferral: Income earned inside the assurance-vie is taxable in the US in the year earned regardless of whether France defers it for French tax purposes.
• FBAR and FATCA reporting: The assurance-vie is a foreign financial account and must be included on FBAR and potentially Form 8938.

The practical advice for US citizens: do not open a new assurance-vie. If you already hold one, get specialist advice before the next filing deadline. Late-filed Form 3520s (required annually) carry substantial penalties. The reporting complexity vastly exceeds any benefit the wrapper provides.

5. IFI — France's Real Estate Wealth Tax

France replaced its broad wealth tax (ISF) in 2018 with the IFI (Impôt sur la Fortune Immobilière), which applies only to net French and worldwide real estate assets. The IFI is payable by French tax residents whose net real estate wealth exceeds €1.3 million on January 1 of the tax year.⁶

IFI Rates (2026)

The IFI applies only if net real estate wealth exceeds €1.3M. Once subject, the tax is calculated on the full wealth using these progressive rates starting from €800,000 (a "decote" — reduction clause — phases in the full liability at the threshold to avoid a sharp cliff).

Key IFI Points for US Citizens

• 5-year exemption on non-French assets: US citizens arriving in France who were not French tax residents for the five years preceding their arrival are exempt from IFI on non-French real estate until December 31 of the fifth year after arrival. This is a meaningful planning window — worldwide real estate is excluded from the IFI calculation during this period.
• US creditability: IFI is generally creditable on Form 1116 as a foreign tax. Because IFI is levied on wealth (real estate) rather than income, it falls in the passive basket on Form 1116 and can only offset US tax on passive income. A specialist can optimize the basket allocation.
• Deductions: Debts secured by French real estate (mortgages) reduce the IFI base. A 30% abatement applies to your primary residence.
• Real estate held through companies: IFI applies to the real estate asset value of companies (French SCIs, French REITs, and certain investment vehicles), not just directly owned property. US citizens holding French real estate through entities should get specialist review of how this flows through to their IFI liability.

6. French Pensions and US Social Security

France has a two-tier pension system: the basic national pension (CNAV — Caisse Nationale d'Assurance Vieillesse) and supplementary pension schemes (AGIRC-ARRCO for private-sector employees). Contributions are mandatory for employees working in France.

US-France Totalization Agreement

The US-France Totalization Agreement prevents dual Social Security taxation and allows contribution periods to be combined for benefit eligibility:⁷

• While working in France under a local employment contract, you generally pay only into the French system (CNAV), not US Social Security — no dual contributions.
• If you haven't accumulated enough quarters in either system to qualify for benefits independently, the totalization agreement lets French contribution periods count toward US Social Security eligibility (and vice versa) — but the actual benefit paid by each country is proportional to that country's credited contributions.
• US citizens on assignment from US employers (posted workers) may continue paying US Social Security and be exempt from French social contributions for up to five years with a Certificate of Coverage from the SSA.
• The totalization agreement addresses Social Security only, not income taxes. It is entirely separate from the income tax treaty.

Note: The Social Security Fairness Act (January 2025) repealed the Windfall Elimination Provision (WEP) and Government Pension Offset (GPO), which previously reduced US Social Security benefits for people also receiving pensions from non-covered employment. Those reductions no longer apply — relevant for US citizens receiving both a French CNAV pension and US Social Security.

French Pension US Tax Treatment

Under Article 18 of the US-France income tax treaty, French-source pension income is generally taxable only in France. However, Article 29 (the saving clause) allows the US to tax US citizens as if the treaty did not exist — so US citizens must still report French pension income on their US return. The practical result: French pension income is included in US gross income, but the French tax paid on it generates a foreign tax credit. A specialist can coordinate the treaty position and FTC to minimize double-taxation on retirement income.

7. FBAR and FATCA for French Accounts

Standard FBAR and FATCA reporting applies in full for all French-held accounts:

• FBAR (FinCEN 114): Required if aggregate foreign account balances exceed $10,000 at any point during the year. Includes French bank accounts (BNP Paribas, Crédit Agricole, Société Générale, LCL, La Banque Postale, online banks like Boursorama), PEA accounts, assurance-vie contracts, and employer pension accounts (CNAV and AGIRC-ARRCO may require FBAR depending on account characterization).
• Form 8938 (FATCA): Required for taxpayers living abroad if foreign assets exceed $200,000 single / $400,000 MFJ at year-end, or $300K / $600K at any point during the year.
• France-IRS data sharing: France operates under a FATCA IGA (Model 1A) — French financial institutions report US-accountholder information to the French tax authority (DGFiP), which shares it with the IRS. Your French bank account activity is visible to the IRS. Compliance is not optional.
• French déclaration 3916: French residents must also declare foreign accounts to the French tax authorities (a requirement for US citizens to be aware of when advising on reverse-side compliance).

8. US-France Tax Treaty: What It Actually Does for US Citizens

The US-France income tax treaty (Convention of August 31, 1994, as amended by protocols through 2009) is extensive — but its benefits for US citizens are more limited than most people expect due to the saving clause.

• Article 29 (saving clause): The US reserves the right to tax its citizens as if the treaty did not exist. For US citizens in France, this means the tiebreaker rules (Article 4), residency-based exemptions, and most income-source rules don't override US citizenship-based taxation. You pay US taxes on worldwide income regardless of how long you've lived in France.
• Saving clause exceptions: A few treaty articles survive the saving clause for US citizens — including Article 18 (pensions, to a degree), Article 19 (government employees), and Article 24 (non-discrimination). These exceptions are narrow and should not be relied on without specialist review.
• Tiebreaker (Article 4): The dual-residency tiebreaker is available to resolve conflicts where someone is both a French and a US tax resident — but this is primarily relevant for non-US-citizen dual residents. US citizens cannot use the tiebreaker to escape US tax; the saving clause prevents it.
• No treaty protection from PFIC rules: The treaty does not override the PFIC regime. Holding French mutual funds triggers §1291 regardless of treaty status.

The practical impact of the treaty for US citizens is mostly indirect: it eliminates French withholding on US-source dividends and interest above certain thresholds, and it provides the FTC framework that prevents true double-taxation — but it does not reduce the filing complexity of being a US citizen in France.

9. The State Tax Trap

Moving to Paris does not automatically end your California or New York state tax liability. Both states aggressively assert continued residency for domiciled taxpayers who have not taken affirmative steps to sever their connection:

• California does not recognize the federal Foreign Earned Income Exclusion. Income excluded on Form 2555 may still be fully taxable by California if you haven't formally abandoned California domicile. California's 9-factor domicile test, the 546-day safe harbor, and the requirement to change all California-based connections (license, voter registration, professional memberships, bank accounts) apply in full. See our state residency planning guide.
• New York has a statutory residency rule: if you maintain a "permanent place of abode" in New York and spend more than 183 days there during the year, you're a New York resident for tax purposes regardless of domicile. Even for those who don't meet that test, New York's clear-and-convincing standard for domicile change makes it one of the hardest states from which to cleanly depart.

State taxes don't benefit from the FTC in the same way federal taxes do. A specialist can model the full federal + state picture before you move — the state piece is often more painful than expected.

10. Before You Move to France: A Planning Checklist

1. Model FEIE vs FTC for your income. For most France-bound earners, FTC wins — but model it before departure, especially if you have self-employment income, are near the FEIE limit, or have significant unearned income.
2. Resolve your US state domicile. Change driver's license, voter registration, bank relationships, and professional memberships. Don't maintain an available pied-à-terre. Document the move date carefully — California and New York audit this.
3. Evaluate your brokerage accounts. US-domiciled ETFs (Vanguard, iShares US, Schwab) are PFIC-free and can be held in taxable accounts while you're in France. French financial institutions may push you toward French or Irish-domiciled ETFs once you're a local resident — resist this.
4. Do not open an assurance-vie. The Form 3520 filing obligation and PFIC risk make it impractical for US citizens. This is the most common expensive mistake US citizens make after arriving in France.
5. Understand PEA limitations. You can hold individual stocks — but no funds. If you're not comfortable managing a stock-only French equity account, don't open a PEA.
6. Assess IFI exposure. If you own real estate anywhere in the world and your net real estate wealth approaches €1.3M, understand how France's IFI will apply. The 5-year exemption on non-French assets gives planning runway for new arrivals.
7. Plan your IRA strategy. If you use FTC (recommended), IRA contribution eligibility is generally preserved as long as you have US earned income not fully offset. Roth conversions before departure while still in the US tax environment may be worth considering.
8. Confirm your posting agreement for Social Security. If assigned by a US employer, request a Certificate of Coverage from the SSA to formalize that you remain in the US Social Security system and are exempt from French social contributions.
9. Identify all accounts to report on FBAR. Every French bank account opened on or after arrival must go on FBAR. Don't wait until tax season — open a list from day one.
10. Get a specialist before year-end of your arrival year. The most expensive mistakes happen in the first year. A US-licensed, France-specialist advisor can prevent the assurance-vie and PEA errors before they become Form 3520 penalty situations.

What a France-Specialist Expat Advisor Handles

Most US financial advisors cannot or will not take clients who live outside the US. Most French conseillers en gestion de patrimoine (CGPs) are expert in French law but have no US tax license or training. The intersection — a US-licensed, fee-only advisor who focuses on US expats in France — is rare. What they do:

• Model FEIE vs FTC for your specific income, filing status, and French tax position — including social charges
• Advise on PEA structuring (individual stocks only) and whether it's worth the complexity vs a US brokerage account
• Review any assurance-vie for Form 3520 obligations and advise on exit or remediation strategies
• Coordinate Form 1116 (FTC) to capture CSG/CRDS as creditable taxes and optimize basket allocation for IFI
• Handle FBAR/FATCA compliance and advise on PFIC elections if you've inherited foreign funds
• Plan the move: state domicile severance, account restructuring, IRA timing, Roth conversion windows
• IFI assessment: worldwide real estate valuation, 5-year exemption planning for new arrivals, mortgage deduction optimization
• Non-US spouse planning: QDOT trust for estate assets approaching the $15M exemption, $190,000/year non-citizen spouse gift exclusion (2026), FBAR signature authority for French accounts held by a French-citizen spouse
