Double Taxation for U.S. Residents: How to Avoid It

What double taxation means

The term covers two different situations, and people search for both.

• International double taxation. Two countries tax the same income. For example, the country where your apartment is located taxes the rent, and the U.S. taxes it again because you are a U.S. resident.
• Corporate (economic) double taxation. A C corporation pays corporate income tax on its profit, and shareholders pay tax again when that profit is paid out as dividends.

Both are legal. The U.S. tax code doesn't prohibit taxing the same income twice. Instead it offers specific relief mechanisms, and you have to claim them correctly on your return. Most of this article is about the international kind; the corporate kind is covered in its own section.

Why U.S. residents are exposed

The U.S. taxes its citizens and resident aliens on worldwide income. IRS Publication 519 puts it plainly: resident aliens are generally taxed on their worldwide income, the same as U.S. citizens. IRS Pub. 519

U.S. tax residency generally depends on the green card test or the substantial presence test. Immigration status and treaty rules can affect the analysis: days in certain categories, such as some students and teachers, may be excluded from the count, and exceptions or residency elections may apply. IRS Pub. 519

Meanwhile, most countries tax income that arises inside their borders, whoever receives it. So a green card holder in Sacramento can owe tax in two places on:

• rent from an apartment abroad;
• interest and dividends from foreign bank and brokerage accounts;
• a foreign pension;
• gain on selling property abroad;
• salary for work done abroad, for example during a long stay back home.

If this is your first year as a U.S. resident, the timing matters too: see our tax checklist for your first year in the U.S. and our guide to green card holder taxes.

The relief tools at a glance

The tools can work together, with one firm rule: foreign tax paid on income you excluded under the FEIE can't be credited or deducted. A treaty and the credit, by contrast, often work side by side: the treaty caps the foreign tax, and the credit applies to the capped amount. IRS: Foreign Tax Credit

The foreign tax credit

The foreign tax credit reduces your U.S. tax dollar for dollar by the foreign income tax you paid on the same income. The IRS notes that in most cases a credit is more valuable than a deduction. IRS

What qualifies

• Generally only foreign income taxes (and war profits and excess profits taxes) qualify. VAT, sales tax and foreign property tax don't.
• The tax must be imposed on you, and you must be subject to U.S. tax on the same income.
• If a treaty caps the foreign tax at a lower rate, only the capped amount is creditable. Any amount over the treaty rate has to be recovered from the foreign country, not from the IRS.

The limit

The credit can't be more than your total U.S. tax liability multiplied by a fraction: foreign-source taxable income divided by total taxable income. IRS: How to figure the credit

Limit = U.S. tax before credits × (foreign-source taxable income ÷ total taxable income)

This simplified formula allocates your regular U.S. income tax proportionally between U.S. and foreign income. Actual Form 1116 calculations may require allocating deductions and interest expense to foreign income, applying category rules and adjusting for capital gains and qualified dividends taxed at lower rates.

The result is a cap on the credit. It isn't necessarily the same as the extra U.S. tax the foreign income added to your return. If the foreign tax is higher than the cap, part of it goes unused this year.

The limit is calculated separately for categories of income. For individuals the two that matter most are passive category income (interest, dividends, most rents) and general category income (wages, active business income). Excess credit in one category can't cover the other.

Unused credit isn't lost right away

Foreign tax over the limit can generally be carried back one year and forward ten years. It only helps in a year when you have room under the limit in the same category. IRS

Timing and currency

Foreign income and foreign tax are reported in U.S. dollars. For foreign tax paid, the general rule is the exchange rate on the date you paid it; taxpayers claiming the credit on an accrual basis generally use the average rate for the year the tax relates to, with conditions. IRS Pub. 514

Timing matters too. On the cash method you claim the credit in the year you pay the tax, so foreign tax paid in a later year doesn't automatically produce a credit in the year the income was earned. A cash-method taxpayer can elect to claim credits when taxes accrue by checking the "Accrued" box on Form 1116 on a timely filed original return; once made, that choice applies to all later years.

When you can skip Form 1116

You can claim the credit directly on Form 1040 without Form 1116 if all three conditions hold:

• all your foreign income is passive category income;
• that income and its foreign tax are reported to you on a payee statement, such as a 1099-DIV from a U.S. broker;
• your total creditable foreign taxes are no more than $300, or $600 on a joint return.

The trade-off: foreign taxes paid or accrued in a year covered by this election can't be carried back or forward. Carryovers to and from other years aren't affected. Form 1116 instructions

Credit or deduction: one choice for the whole year

Generally, each year you choose either the credit or the deduction for all qualified foreign income taxes paid or accrued for that year. Limited exceptions apply, for example for foreign taxes that aren't allowed as a credit. IRS Pub. 514

Two worked examples

Simplified illustration, not a specific jurisdiction. Assumptions for both examples:

• a married couple filing jointly, both green card holders, living in California;
• total taxable income of $100,000, of which $12,000 is foreign-source taxable income from renting out an apartment abroad (passive category), after all expense and deduction allocations required for Form 1116;
• regular U.S. federal income tax before credits of $13,000, an assumed amount rather than a calculation under the 2026 brackets;
• no other foreign income and no carryovers.

Example A: the foreign country taxes the rent at 10%

The couple's remaining federal income tax is $11,800. Adding the $1,200 foreign tax gives a combined federal-and-foreign total of $13,000 on all their income, before California tax. The $1,560 limit is an allocation: it isn't necessarily the extra U.S. tax the rent added to their return.

Example B: the foreign country taxes the rent at 30%

Federal tax of $11,440 plus $3,600 of foreign tax gives a combined total of $15,040 before California tax, which is $2,040 more than in Example A. That $2,040 may be used in another year through the carryback or carryforward, but only if there is room under the passive-category limit in that year. Using the full limit doesn't necessarily remove every dollar of U.S. tax attributable to the rent.

In both examples California calculates the taxable rental income under its own rules and gives no credit for the foreign tax. That gap is covered below. Which expenses can be deducted from rental income, including for a property abroad, is explained in our guide to rental property tax deductions.

The foreign earned income exclusion

The FEIE lets qualifying taxpayers exclude foreign earned income, meaning wages or self-employment income for work done abroad. For 2026 the maximum is $132,900 per qualifying person. Rev. Proc. 2025-32 via KPMG

To qualify, your tax home must be in a foreign country, and you must pass one of two tests:

• Bona fide residence: you are a bona fide resident of a foreign country for an uninterrupted period that includes an entire tax year. Besides U.S. citizens, this test is open only to resident aliens who are citizens or nationals of a country with a U.S. income tax treaty.
• Physical presence: you are physically present in a foreign country or countries for at least 330 full days during any 12 consecutive months.

IRS: Foreign Earned Income Exclusion

That's why the FEIE rarely helps people who live in the U.S. Rent, interest, pensions and capital gains aren't earned income, and a U.S. tax home fails the test. Remote work for a foreign employer while you live in California doesn't qualify either: the work is performed in the U.S.

Two more limits matter. The exclusion doesn't reduce self-employment tax. And tax on any income you don't exclude is calculated at the rates that would apply without the exclusion, so excluded income still pushes the rest into higher brackets.

The exclusion amount is indexed for inflation each year, so check the figure for the year you are filing.

Tax treaties and dual residency

The U.S. has income tax treaties with dozens of countries. For a U.S. resident they mainly do two things: lower the tax the other country withholds on interest, dividends or royalties, and settle which country treats you as a resident if both claim you.

The saving clause

Most U.S. treaties contain a saving clause: the U.S. keeps the right to tax its own citizens and residents as if the treaty didn't exist, except for specific listed exceptions. In practice a treaty rarely reduces your U.S. tax on foreign income. Relief on the U.S. side still comes mostly from the foreign tax credit. Some treaties do carve out exceptions, for example for certain pensions or for students and researchers. IRS: Claiming tax treaty benefits

Dual residents and the tie-breaker rule

A resident alien can also be a tax resident of another country at the same time. Treaties resolve this with tie-breaker rules. A dual-resident alien who qualifies under an applicable treaty may claim nonresident treatment for figuring U.S. income tax, generally by filing Form 1040-NR with Form 8833 attached. U.S. citizens don't become nonresident aliens just because a treaty assigns their residence to another country. IRS Pub. 519

For green card holders this is a serious decision. Pub. 519 warns that in some cases treaty-based nonresident treatment can trigger the section 877A expatriation tax for long-term residents. It can also raise questions about whether you have kept your permanent residence. Get advice before you take this position.

Form 8833 and the penalty

If you take a treaty position that overrides or modifies the Internal Revenue Code and it reduces your tax, you generally must disclose it on Form 8833. Some situations are exempt. The penalty for failing to disclose is $1,000 for each failure. IRS

The U.S.–Russia treaty suspension

Russia suspended key provisions of its income tax treaty with the U.S. by decree on August 8, 2023. The U.S. confirmed a mutual suspension on June 17, 2024. Under IRS Announcement 2024-26, the suspension took effect on August 16, 2024. EY tax alert

The suspended provisions are paragraph 4 of Article 1, Articles 5 through 21, Article 23 and the Protocol. That covers the articles on business profits, dividends, interest, royalties and most other categories of income. IRS: Russia treaty documents

Article 22, the treaty's double-tax relief article, isn't itself on the list. However, paragraph 4 of Article 1 protected specified treaty benefits from the saving clause, so its suspension can affect treaty-based relief. The result depends on the taxpayer and the income. The suspension continues until the two governments decide otherwise; the treaty itself hasn't been terminated.

What this means for you

• In Russia: treaty-reduced withholding rates on income paid to U.S. residents no longer apply, so Russian domestic rates do.
• In the U.S.: the foreign tax credit itself comes from the Internal Revenue Code, not from the treaty. Russian income tax on Russian-source income can generally still be credited, subject to the same limit and categories. Russia isn't on the IRS list of sanctioned countries for which the credit is denied. IRS Pub. 514
• U.S.-source income paid to Russian residents that used to qualify for reduced treaty rates, such as dividends, is now generally withheld at the statutory 30% rate. Withholding agents may not accept treaty claims for payments made on or after August 16, 2024.
• Higher Russian tax can increase the amount of foreign tax that exceeds the applicable Form 1116 limit. Whether the excess can be used depends on the income category, deduction allocations and available carryback or carryforward capacity.

The IRS treaty list also marks the treaty with Belarus as partially suspended. Treaties with Ukraine and Kazakhstan are listed without that caution. IRS: Treaties A–Z

Social Security is a separate issue

Income tax treaties don't cover social security contributions. That's the job of totalization agreements. The U.S. has them with about 30 countries, mostly in Europe plus Canada, Japan, South Korea, Australia, Brazil, Chile and Uruguay. There are none with Russia, Ukraine, Kazakhstan, Belarus, Uzbekistan, Armenia, Georgia or Moldova. SSA

We also cover this topic for Russian-speaking readers in our guide to U.S. individual taxes in Russian.

Gaps: California and the 3.8% NIIT

California gives no credit for foreign taxes

California's other state tax credit covers net income taxes paid to another state or U.S. possession only. The Schedule S instructions explicitly exclude taxes paid to any foreign country. FTB Schedule S instructions (2025)

California also has no equivalent of the FEIE. Income excluded on the federal return is added back on Schedule CA. FTB Pub. 1001

So for a California resident, foreign income is often taxed by the foreign country, by the U.S. after the credit, and by California in full. That state layer can remain even when the federal foreign tax credit substantially reduces your regular U.S. income tax.

The net investment income tax

The 3.8% net investment income tax is charged on the lesser of your net investment income or the amount by which your modified adjusted gross income exceeds $200,000 for single filers, $250,000 for joint filers or $125,000 for married filing separately. IRS Topic 559

Foreign tax credits generally don't offset the NIIT under the Code: the credit applies to regular income tax, and the NIIT is a separate tax. On August 31, 2026, the Federal Circuit also rejected the treaty-based credit claims at issue under the U.S.–France and U.S.–Canada treaties in Christensen v. United States and Estate of Bruyea v. United States. KPMG

Foreign rent, interest or capital gains can therefore carry this 3.8% on top even when the regular federal tax on them is fully offset.

Corporate double taxation

A C corporation pays the flat 21% federal corporate tax on its profit. When the after-tax profit is paid out as qualified dividends, shareholders pay tax again at capital gains rates of 0%, 15% or 20%. High earners may also owe the 3.8% NIIT. IRS Topic 409

LLCs taxed as partnerships or sole proprietorships, and S corporations, are pass-through entities. Their profit is taxed once, on the owners' returns. Pass-through isn't automatically cheaper, though. The owner's bracket, self-employment or payroll tax, state tax and plans to reinvest profit all change the answer, and there are cases where a C corporation still comes out ahead. California adds its own entity-level taxes and fees on top.

Checklist before you file

• List every foreign income item and asset sale for the year: rent, interest, dividends, pension, wages for days worked abroad. For sales, gather the proceeds, acquisition cost, purchase and sale dates and expense records.
• Get proof of foreign tax actually paid or withheld: foreign returns, withholding certificates, bank statements. Translate key documents.
• Check whether a treaty caps the foreign rate. If too much was withheld, claim the refund abroad, because the IRS won't credit the excess.
• Split foreign income into passive and general categories before calculating the limit.
• Review foreign tax credit carryforwards from prior years and check whether any current-year excess can be carried back to the preceding year.
• Decide whether to claim a credit or an itemized deduction for qualified foreign income taxes, taking the limited exceptions into account.
• If you consider a treaty tie-breaker position as a green card holder, get advice on immigration and expatriation consequences first.
• Plan for California tax on the foreign income with no state credit for the foreign tax, and for the 3.8% NIIT if your modified AGI is above the threshold.
• Report the foreign accounts themselves: FBAR and possibly Form 8938. See our FBAR filing requirements guide.

FAQ

Is double taxation legal in the United States?

Yes. U.S. law allows the same income to be taxed by the U.S. and by another country, and it also taxes C corporation profits again when they are paid out as dividends. Relief isn't automatic: you claim the foreign tax credit, the foreign earned income exclusion or a treaty benefit on your return.

Do green card holders pay U.S. tax on foreign income?

Yes. Green card holders are U.S. tax residents and are generally taxed on worldwide income, the same as U.S. citizens. Foreign income tax already paid on that income can usually be claimed as a foreign tax credit on Form 1116, up to the U.S. tax on the same income.

Can I claim the foreign tax credit and the FEIE on the same income?

No. You can't take a credit or a deduction for foreign tax paid on income you exclude under the foreign earned income exclusion. You can use the exclusion for some income and the credit for other income, such as foreign rent.

What happens if the foreign country taxes my income at a higher rate than the U.S.?

The credit is capped at your U.S. tax on that foreign income, calculated with the Form 1116 fraction. The excess foreign tax can generally be carried back one year and forward ten years and used in a year with room under the limit in the same income category.

Does California give a credit for foreign income taxes?

No. California's other state tax credit applies only to net income taxes paid to other U.S. states and possessions. California also has no equivalent of the federal foreign earned income exclusion, so California residents generally pay state tax on foreign income, calculated under California rules, with no credit for the foreign tax.

Is the U.S.–Russia tax treaty still in effect?

Formally yes, but most of its operative provisions have been suspended since August 16, 2024, including the articles on dividends, interest and royalties. U.S. residents can generally still claim the foreign tax credit for Russian income tax under the Internal Revenue Code, which works separately from the treaty.

Do I need to report foreign financial accounts if I owe no extra tax?

Yes, if you meet the thresholds. FBAR (FinCEN Form 114) is required when the combined value of foreign financial accounts in which you have a financial interest or signature authority exceeded $10,000 at any time during the year, regardless of whether any tax is due. Form 8938 has separate, higher thresholds.
