How to Use the Foreign Tax Credit (Form 1116) to Avoid Double Taxation as an American in France

Updated: Fabruary 11, 2026

Most Americans in France pay meaningful French income tax. The Foreign Tax Credit (FTC), claimed on Form 1116, is the primary mechanism for ensuring those French taxes reduce, rather than stack on top of, US tax on the same income. The concept is simple: taxes you have already paid to France on a given item of income generally reduce your US tax liability on that same income dollar for dollar, subject to a limitation. The execution is not simple, because the IRS requires you to calculate the credit separately for different categories (baskets) of income, apply a mathematical limitation to each basket, track unused credits as carryovers, and potentially recalculate the credit for the Alternative Minimum Tax. This article covers each layer of Form 1116 specifically for Americans living in France, including which basket applies to which type of French-taxed income, how the limitation works in practice, when the FTC produces better results than the FEIE, and what carryover mechanics mean for multi-year planning. This article is for informational purposes only and does not constitute tax or legal advice. Tax rules are complex and change frequently: consult a qualified cross-border tax professional before making any filing or planning decisions.

The Basic Mechanics: How the Foreign Tax Credit Works

The Foreign Tax Credit is a credit against your US federal income tax liability, not a deduction against income. A credit reduces tax dollar for dollar; a deduction only reduces taxable income. If you owe $15,000 in US federal income tax and you have $12,000 in creditable French taxes paid on the same income, your US tax liability is reduced to $3,000. The credit eliminates the double taxation rather than merely reducing its impact.

To be creditable, a foreign tax must meet four requirements. It must be an income tax (or a tax in lieu of income tax). It must be a legal and actual foreign tax liability, not a voluntary payment. It must be imposed on you as the taxpayer. And it must be paid or accrued during the tax year for which you are claiming the credit.

French income tax (impôt sur le revenu) satisfies all four requirements and is fully creditable. The French prélèvements sociaux (CSG, CRDS, and related social contributions), however, present a more complex picture. The IRS has historically taken the position that French social contributions are not creditable because they are not income taxes. As a result, the prélèvements sociaux on investment income, rental income, and similar passive income received by French residents are often not creditable on Form 1116. This is one of the most significant practical limitations for Americans in France with investment portfolios or rental income: the approximately 17.2% combined social contribution rate on that income may not generate any FTC benefit. For recent administrative guidance on this, see the IRS's International Taxpayer guidance and consult a cross-border tax advisor for the current state of this issue for your specific income types.

Cash basis versus accrual basis: US taxpayers generally have the choice to claim the FTC based on taxes paid during the year (cash basis) or taxes accrued during the year but not yet paid. For most Americans in France who pay French income tax annually based on their prior-year return, the accrual method can match the French tax accrual with the US taxable year that generated the underlying income. This is a methodological election on Form 1116 and an area where the choice can meaningfully affect the timing of FTC benefit.

The Income Baskets: Why Category Matters

The IRS requires that the foreign tax credit be calculated separately for different categories of income, called baskets. You complete a separate Form 1116 for each basket relevant to your situation. Credits cannot be mixed between baskets: an excess credit in the passive income basket cannot offset a limitation shortfall in the general limitation basket.

The baskets most relevant to Americans in France are:

The general limitation basket covers most ordinary income: wages, salaries, self-employment income, active business income, and most pension income (including distributions from US retirement accounts that France taxes as pension income). If you are employed in France or earn self-employment income that is taxed in France, the French taxes on that income belong in the general basket.

The passive income basket covers investment income: dividends, interest, royalties, rents (in most cases), and capital gains that are not part of an active business. If you hold US or French investments that generate dividends or interest, and France taxes that income, those French taxes belong in the passive basket. This is the basket where the prélèvements sociaux limitation matters most: many Americans with investment portfolios find they have significant French taxes on investment income but cannot credit the prélèvements portion.

The section 901(j) basket applies to income from sanctioned countries and is not relevant for France.

The foreign branch income basket covers income of US branches of foreign corporations and applies primarily to corporate structures rather than to individual Americans in France.

For most individual Americans in France, the relevant baskets are general limitation and passive. If you have both employment income and investment income taxed by France, you complete two separate Form 1116 calculations: one for each basket.

The Limitation Calculation: Why You Often Cannot Credit Everything

The FTC limitation ensures you cannot use foreign taxes to offset US tax on income that is not actually subject to foreign tax. The limitation caps the credit at:

(Foreign source income in the basket / Worldwide income) × US tax before credits

This formula means the credit is limited to the proportion of your US tax that is attributable to foreign source income. If France is your only source of foreign-taxed income and all of your income is foreign-source (which is not typically the case for Americans with US-based assets), the limitation is your entire US tax. More commonly, Americans in France have a mix of US-source income (US Social Security, US pensions, US dividends, US rental income) and French-source income, and the limitation applies proportionally.

The limitation is calculated separately for each basket. Here is a simplified illustration:

An American in France has: €80,000 of French employment income (general basket), $20,000 of US Social Security income (general basket, US-source), and $15,000 of US dividends (passive basket, US-source).

Total worldwide income for limitation purposes is approximately $130,000 (combining all sources at relevant exchange rates). French employment income is foreign-source for the general basket. US Social Security and US dividends are US-source.

For the general basket, the foreign-source fraction is approximately €80,000 / $130,000 (converted), or roughly 60-65%. The general basket credit is limited to 60-65% of your total US tax before credits.

For the passive basket, the US dividends are US-source income, and if there is no French-sourced passive income at all (or only prélèvements-only income), the foreign source fraction for the passive basket may be zero or very small, and the passive basket limitation may effectively be zero.

This is the practical reason why many Americans in France who pay substantial French taxes do not eliminate their US tax liability entirely: the US-source income they retain (Social Security, US pensions, US dividends) is not foreign-source income for the limitation, so the credit on it is proportionally reduced.

General Basket in Detail: Employment and Pension Income

For Americans employed in France, the general basket calculation is the most important. The French income tax paid on French wages is fully creditable in principle, subject to the limitation. For Americans who have French income tax withheld at source (précompte, applicable in some employment situations) or who pay via acomptes provisionnels (quarterly installments), those payments count as foreign taxes paid and are aggregated for the year.

The French income tax assessed on your French return (impôt sur le revenu net) is the figure that goes on Form 1116 as creditable foreign taxes paid. This figure appears on your avis d'imposition (annual tax assessment). It does not include the prélèvements sociaux, which appear as a separate line on the avis d'imposition and, as noted above, are generally not creditable.

For Americans receiving French pension income or income from French employment after retirement from a French company, the same general basket applies. The French income tax on those pension distributions is creditable.

The US-France treaty's taux effectif mechanism (described in our French income tax return guide) means that some income, such as US-source employment income earned by a French resident, inflates the French tax rate without generating actual French income tax on that specific income. In those cases, there is no creditable French tax on the US-source portion to enter on Form 1116. The credit only applies where actual French tax was assessed and paid on foreign-source income.

Passive Basket in Detail: Dividends, Interest, and Rental Income

The passive basket is where Americans with US or French investment portfolios encounter the most complexity in the France context.

For US-source dividends and interest received by an American living in France, France's right to tax these as a resident of France depends on the treaty category. The treaty generally permits France to tax US-source dividends at up to 15% withholding (at the US source) plus French income tax at marginal rates on the net dividend (after a treaty-provided abattement), with a credit for the US withholding. The French income tax actually paid on these dividends is creditable in the passive basket. The prélèvements sociaux on the same dividends are generally not.

For French-source dividends (from French company shares), France withholds a portion and the remainder is taxable at marginal rates or at the flat prélèvement forfaitaire unique (PFU) rate of 30% total (including 17.2% prélèvements). The French income tax component of the PFU (the 12.8% income tax portion) is creditable; the prélèvements portion (17.2%) is generally not.

For US-source capital gains, France taxes them as a French resident. The French income tax on the gain is creditable in the passive basket. Again, the prélèvements sociaux are generally not. This is a significant planning consideration for Americans who realize large capital gains in France: the effective French tax rate on the gain may be 30% (PFU) or higher at marginal rates, but only the income tax portion generates a creditable FTC, and the limitation then further restricts how much of that credit can offset US tax.

Rental income from foreign property (whether French or US) falls into the passive basket for FTC purposes unless the rental activity rises to the level of an active trade or business. For most Americans with a few rental properties, rental income is passive. French income tax on French rental income is creditable in the passive basket. For US rental income taxed by France as a French resident, the same passive basket applies.

FTC Versus FEIE: The Core Decision for Americans in France

The FEIE (Foreign Earned Income Exclusion, Form 2555) and the FTC (Form 1116) cannot be applied to the same income. The choice between them is one of the most consequential annual tax decisions for Americans in France, and it is not always the same answer from year to year or even from one income type to another.

The FEIE excludes up to a maximum amount of foreign earned income from US taxable income entirely ($130,000 in 2025, adjusted for inflation). Income excluded under the FEIE is not taxed in the US, but it also generates no FTC benefit, because you cannot claim a credit for taxes paid on excluded income.

The FTC credits French taxes against US taxes on a dollar-for-dollar basis, subject to the limitation. Excess credits can be carried over.

For Americans in France, the FTC generally produces better results than the FEIE in several situations:

When your French income tax rate significantly exceeds your US marginal rate. France's marginal rates go to 45%. If your French tax rate on employment income is 41% or 45% and your US marginal rate is 22% or 24%, the French taxes paid significantly exceed the US tax on the same income. The FTC eliminates the US tax on that income entirely, and the excess credit carries forward.

When you have significant US-source income alongside French income. The FEIE only excludes foreign earned income. US-source income (dividends, interest, Social Security) is still taxed in the US regardless of whether you claim the FEIE. The FTC on French income can potentially offset US tax on the entire package, while the FEIE only addresses the French income portion.

When you want to maintain IRA contribution eligibility. As explained in our 401(k) and IRA in France guide, the FEIE reduces your earned income for IRA contribution purposes. The FTC does not. Americans who want to continue making IRA contributions must have unexcluded earned income.

The FEIE can be better when: your US marginal rate exceeds your French rate (less common in France given France's higher marginal rates for high earners); when you are in the early years in France and have not yet generated a high French tax bill; or when your income mix is predominantly earned income at lower brackets.

In practice, many cross-border tax advisors run the calculation both ways for each year and choose the method that produces the lower combined tax. The election is annual, and switching from FEIE to FTC requires a mandatory six-year period before switching back, so the multi-year consequences must be considered.

The Limitation in Practice: Excess Credits and Carryovers

When your creditable foreign taxes exceed the FTC limitation in a given year (which happens when your French tax rate is higher than the US rate on the same income, as is common in France), you have an excess credit. Excess credits cannot be used in the current year, but they can be:

Carried back one year: you amend the prior year's return to apply the excess credit.

Carried forward ten years: unused excess credits from the current year can be applied in any of the next ten tax years in the same basket, subject to that future year's limitation.

For Americans who are newly established in France and who have relatively high French tax bills from the start, excess credits in the general basket are common. These carryovers accumulate and can be valuable when the limitation in a future year is higher (for example, a year with high US-source income that increases the foreign-source fraction).

Tracking carryovers requires maintaining records of each year's Form 1116 for each basket. The carryover amounts are reported on Form 1116 Part III and Part IV. Each basket's carryovers are tracked separately. When you switch between the FEIE and FTC, excess credits from prior FEIE years may be limited in their applicability, which is another reason the FEIE-to-FTC election transition requires careful modeling.

In our experience, excess credit carryovers are one of the most systematically mismanaged elements of American expat tax returns in France. Americans who use a US-only CPA who is not familiar with the French tax system often fail to report and track excess credits on Form 1116 Part III, which means the carryovers are lost rather than accumulated for future use. A cross-border tax advisor who completes Form 1116 correctly each year preserves and tracks these carryovers as a long-term tax asset.

The AMT Foreign Tax Credit

The Alternative Minimum Tax (AMT) applies to Americans whose regular tax liability falls below the AMT calculation. If you are subject to AMT in any year, you must also calculate a separate AMT foreign tax credit, which is allowed against the AMT liability (not the regular tax).

The AMT FTC is calculated on a separate Form 1116 for AMT purposes. It follows the same general structure as the regular FTC but uses the AMT income base rather than the regular tax income base. The AMT FTC is generally more limited than the regular FTC: the AMT limitation restricts the credit to 90% of the AMT (pre-credit) liability in some circumstances, leaving at least 10% of AMT payable even if your foreign taxes are substantial.

For most Americans in France whose French tax rates are high, the AMT is less likely to apply, because the high FTC tends to reduce regular US tax below the AMT threshold. However, Americans with significant US-source passive income (US dividends, US capital gains) can still encounter AMT in specific income configurations, particularly when the regular FTC limitation results in a lower effective credit than expected.

AMT FTC carryovers are tracked separately from regular FTC carryovers and can be carried forward for ten years under similar rules.

The AMT calculation is complex enough that it should not be approached without tax software or a qualified preparer. What we see most often is Americans who self-prepare their returns and correctly compute the regular Form 1116 but entirely omit the AMT FTC calculation, producing an overstated AMT liability in years where the AMT applies.

Special Situations: The Per-Country Election and Passive Income Details

Form 1116 normally aggregates all foreign taxes in a basket regardless of which country paid them: taxes paid to France and taxes paid to any other country go into the same basket. This is called the overall limitation method.

There is an election, available to certain taxpayers, to use a per-country limitation method, which calculates the FTC limitation separately for each country. The per-country method can be beneficial in specific circumstances, such as when taxes paid to one high-tax country (like France) are limited by the overall basket calculation due to low-tax foreign income in the same basket from another source. It can be harmful in other configurations.

For Americans whose foreign income is predominantly from France and who do not have significant other foreign income in the same basket, the per-country election often makes no material difference. It is worth discussing with a cross-border advisor if you have multi-country income in the same basket.

For the passive basket specifically, qualified dividend income from non-US corporations and certain capital gains receive specific treatment in the limitation calculation. The numerator of the limitation fraction for passive income uses net passive income, meaning passive income reduced by expenses allocable to it. Passive losses in France (from rental activity, for example) reduce the numerator and therefore the limitation for the passive basket, which can restrict the creditable FTC on other passive income. This interaction between French passive losses and the passive basket limitation is a planning consideration for Americans with French rental properties that generate losses in early years.

What Goes Where on Form 1116: A Practical Map

Part I: identifies the basket and lists your foreign-source gross income in that category. For the general basket: your French-source wages, pension income, and other earned income. For the passive basket: French-source dividends, interest, capital gains, and rental income.

Part II: lists the foreign taxes paid or accrued. For the general basket: the French income tax (impôt sur le revenu) allocated to your French employment and pension income. This figure comes from your avis d'imposition, specifically the ligne showing your impôt net à payer, allocated across income categories. For the passive basket: the income tax component of French taxes on your investment income. All figures in dollars at the exchange rate applicable to the date of payment or accrual.

Part III: the limitation calculation. Line 34 is the US tax before credits (from your regular Form 1040 calculation). Line 38 is the foreign-source income fraction for the basket. Line 40 is the limitation (the product of lines 34 and 38). Line 41 is the credit actually allowed (the lesser of line 40 and the total creditable foreign tax in Part II).

Part IV: carryovers. Line 10 lists unused prior-year credits in the basket. Line 12 shows how much of those carryovers can be used in the current year (limited by the current year's limitation minus current year's creditable taxes). The remaining excess becomes a new carryover.

Converting French tax figures to dollars is required for all amounts on Form 1116. Use the exchange rate on the date of payment (for cash basis) or accrual (for accrual basis). The IRS accepts the annual average exchange rate for most purposes. The annual average rate for major currencies is published by the IRS on its international exchange rate page.

Common Mistakes to Avoid

Claiming the FTC on prélèvements sociaux without checking the current IRS position is the most consistent error we see from Americans self-preparing returns in France. Entering the full avis d'imposition amount (which includes both impôt sur le revenu and prélèvements sociaux) as creditable foreign tax overstates the credit and creates an IRS examination risk.

Not completing a separate Form 1116 for each basket and instead filing a single combined Form 1116 is a structural error that understates or incorrectly calculates the limitation. The IRS requires separate forms for each basket.

Failing to track and carry forward excess credits is an annual omission that compounds over time. In years where the general basket limitation exceeds the French taxes paid (for example, a year with high US-source income in the basket), prior-year carryovers can eliminate US tax entirely. Losing them by not entering them on Part IV is a real and recoverable loss.

Not considering the FEIE-to-FTC switch implications before making the election is a multi-year planning error. Switching from the FEIE (Form 2555) to the FTC has a mandatory six-year waiting period before reverting. Modeling the multi-year trajectory before switching, not just the current year, is essential.

Using the wrong exchange rate for French tax conversion is a common preparation error that produces a technically incorrect Form 1116. The IRS annual average exchange rate should be used consistently rather than a spot rate from a financial data source.

Practical Checklist

Gather your French tax documents: your avis d'imposition for the year, broken down by tax type (impôt sur le revenu separately from prélèvements sociaux), your French income categorized by type (wages, dividends, rental income, etc.).

Identify which baskets apply: general (wages, pensions, self-employment) and passive (dividends, interest, capital gains, rental income). If you have both, prepare two Form 1116 instances.

Determine whether French taxes on each income category are creditable income taxes or non-creditable contributions (prélèvements sociaux). Only include the income tax component on Form 1116.

Convert all French tax figures to dollars using the IRS annual average exchange rate for the year.

Complete Part I for each basket with the correct foreign-source income for that category.

Complete Part II with the creditable French taxes for that basket.

Complete the Part III limitation calculation and determine the allowable credit.

Complete Part IV with any carryovers from prior years and calculate any new carryover.

If AMT applies, complete a separate Form 1116 for AMT purposes.

Review the FEIE versus FTC decision for the year by modeling both methods and comparing results, taking multi-year implications into account.

When to Get Help

Form 1116 is one of the few elements of an American expat's tax return where a preparation error has both an immediate cost (wrong current-year credit) and a multi-year cost (lost carryovers). It is also the form where the interaction between French tax law, the treaty, and US Internal Revenue Code produces the most counterintuitive results.

Americans with exclusively French-source earned income and no investment portfolios can often manage Form 1116 correctly with good tax software (TurboTax for foreign countries, TaxAct, or expat-specialist software like Greenback). Americans with investment portfolios, prélèvements sociaux implications, retirement distributions, passive basket losses, or AMT exposure should work with a cross-border CPA who understands both the French avis d'imposition structure and the Form 1116 basket mechanics.

For Americans who are already in France and want to confirm prior returns were done correctly, a cross-border tax professional can review Form 1116 for prior years and identify any missed carryovers that can still be claimed on an amended return.

FAQ

What is the difference between the Foreign Tax Credit and the Foreign Earned Income Exclusion for Americans in France?

The FEIE (Form 2555) excludes up to a capped amount of foreign earned income from US taxable income, eliminating US tax on that income but also generating no credit for French taxes paid on it. The FTC (Form 1116) credits French income taxes against your US tax liability on a dollar-for-dollar basis, subject to the limitation. Both cannot be applied to the same income. In France, where marginal income tax rates are higher than US rates for most income levels, the FTC typically produces better results because the French taxes paid often exceed the US tax on the same income, generating excess credits that carry forward. The FEIE has the advantage of simplicity and can be better when French tax rates are low relative to US rates. The decision requires modeling both methods for your specific income profile. For the IRA contribution interaction with the FEIE, see the IRS Publication 54 for Americans abroad.

Are French prélèvements sociaux (CSG, CRDS) creditable on Form 1116?

The IRS has generally taken the position that French prélèvements sociaux (CSG, CRDS, and related contributions) are not creditable on Form 1116 because they do not qualify as income taxes under IRC Section 901. This issue has a complex legal history, including a 2019 court case (Eshel) that challenged the IRS position, and the current state of the guidance should be verified with a cross-border tax advisor. For most practical purposes, Americans filing Form 1116 should include only the impôt sur le revenu component from their avis d'imposition as creditable, not the full amount including prélèvements. Incorrectly claiming prélèvements sociaux as creditable taxes overstates the FTC and creates examination risk.

What happens when my foreign tax credit exceeds the limitation in France?

When your creditable French taxes in a basket exceed the FTC limitation for that basket, you have an excess credit. Excess credits can be carried back one year (by amending the prior return) or carried forward for up to ten years in the same basket. The carryover is recorded on Form 1116 Part IV each year and applied in future years when the limitation exceeds the current-year creditable taxes. For Americans in France who consistently pay high French taxes, excess credit carryovers in the general limitation basket are common and can be valuable in future years when US-source income increases or when the income mix shifts. Proper tracking of carryovers on each year's Form 1116 is essential to preserve this multi-year tax asset.

How does the per-country election for Form 1116 work, and should Americans in France use it?

The standard method for Form 1116 aggregates all foreign taxes in a basket regardless of country of payment (the overall limitation method). A per-country election allows calculating the FTC limitation separately for each country. For Americans whose foreign income is predominantly from France with no other significant foreign income in the same basket, the per-country election rarely makes a material difference. It can be beneficial in specific multi-country configurations where low-tax foreign income in one country reduces the overall basket limitation and prevents full crediting of high-tax French income. Unless you have multi-country foreign income in the same basket, the per-country election is unlikely to improve your result in the France-only context. Discuss it with a cross-border advisor if you have other foreign income alongside your French income.

Can I still claim the Foreign Tax Credit if I have already filed Form 2555 (FEIE) in prior years?

Yes, but switching from the FEIE to the FTC carries a significant restriction: once you revoke the FEIE election, you cannot re-elect the FEIE for at least six years without IRS consent. The switch from FEIE to FTC is therefore a multi-year commitment that should be modeled across the expected period of French residency before executing. In years where the FTC is better on a standalone basis but the FEIE generates better results over the full six-year horizon (because future years are expected to have low French tax rates), switching may not be optimal. The correct approach is to project the combined US-France tax for each scenario over the expected residency period with your specific income profile. See the IRS guidance on revoking the FEIE election for the procedural requirements.

Conclusion

The Foreign Tax Credit on Form 1116 is the most powerful tool Americans in France have for preventing double taxation on income that France taxes at meaningful rates. Used correctly, it eliminates US tax on foreign-source income and generates carryovers that can provide future-year tax reduction. Used incorrectly, by including non-creditable prélèvements sociaux, failing to track carryovers, or misassigning income to baskets, it produces compliance risk and permanently lost tax benefits.

The FTC decision, basket assignment, limitation calculation, and carryover tracking are each individually manageable, but their interaction requires structured attention each year. Americans in France with significant French tax bills should treat Form 1116 as a core component of their annual tax planning, not an afterthought completed after the rest of the return.
