Foreign withholding tax: A complete guide for US expats in 2026

Foreign withholding tax is a tax deducted at source by a foreign government or a US withholding agent on income paid to nonresident aliens or US persons receiving foreign-source income. It is a mandatory deduction made before income reaches you.

US taxpayers can often recover it through the foreign tax credit on Form 1116.

Every country that taxes investment income has some version of the same mechanism: the payer holds back a percentage of dividends, interest, royalties, or other income before sending the rest to you.

For US citizens and green card holders living abroad, this means the withholding tax on your foreign income is already gone by the time it hits your brokerage account or bank statement.

The standard withholding rate varies by country but typically falls between 10% and 30%. The US itself applies a default 30% rate on payments to nonresident aliens.

Tax treaties between the US and more than 60 countries can reduce or eliminate that rate – but only if you file the right paperwork before the payment is made.

Based on TFX client scenario: A US expat in Germany receives $12,000 in dividends from a German company. A US taxpayer may have German tax withheld at the domestic rate, but the amount eligible for the foreign tax credit depends on the taxpayer's legal German tax liability and treaty status. If part of the withholding is refundable under an applicable treaty, that refundable amount generally cannot be claimed as a US foreign tax credit.

 

How foreign withholding tax works: The mechanism explained

The withholding agent – not the taxpayer – is legally responsible for deducting and remitting the tax to the relevant authority.

Chapter 3 of the Internal Revenue Code and Form 1042-S govern how this process works for US-source payments to foreign persons.

Here is the step-by-step process:

1. Income is earned. You receive dividends, interest, rent, royalties, or another form of income from a source in a foreign country – or a foreign person receives US-source income.
2. The withholding agent deducts tax before payment. The payer – a bank, brokerage, employer, or other institution – withholds tax at the applicable rate and sends it to the local tax authority.
3. The reduced amount is remitted to the taxpayer. You receive the net amount after withholding. If a $1,000 dividend is subject to 15% withholding, you receive $850.
4. Form 1042-S documents the withholding. For US-source income paid to foreign persons, the withholding agent issues Form 1042-S showing the gross income, the tax withheld, and the applicable treaty rate. For foreign-source income paid to US persons, the foreign institution provides an equivalent statement.
5. The taxpayer claims a credit or deduction on the US return. US taxpayers report the gross income and claim the withholding tax on foreign payments as a credit on Form 1116 or as an itemized deduction on Schedule A. The credit is almost always more valuable.

Foreign withholding tax rates by country (tax year 2025)

Treaty-reduced rate for qualifying US treaty residents. Rates shown assume the beneficial owner is a resident of the United States for purposes of the applicable treaty and satisfies any other treaty requirements. US citizenship alone does not establish eligibility for these rates.

 

NOTE! Rates shown are general dividend withholding rates. Taxpayers should verify current treaty provisions, as rates vary by income type and the recipient's residency status. Japan's 20.42% standard rate applies to dividends on non-listed shares; dividends on listed shares are generally subject to a lower 15.315% domestic rate before any treaty reduction.

The rates also depend on whether you filed a valid Form W-8BEN or equivalent certificate with the payer.

Foreign tax withholding on dividends: What US investors must know

Foreign governments withhold tax on dividends before they reach your US brokerage account. This applies whether you hold individual foreign stocks directly or own shares through a foreign-domiciled fund.

The withholding is automatically deducted by the foreign company or its custodian, meaning US investors often pay it without realizing it.

What you need to know about foreign dividend withholding:

• Qualified vs. non-qualified foreign dividends. Qualified dividends from certain foreign corporations are taxed at the preferential US capital gains rate of 0%, 15%, or 20% (2025). Non-qualified dividends are taxed at your ordinary income rate. The foreign withholding applies regardless of this US classification.
• Form 1099-DIV box 7 reports foreign taxes paid on dividends. This is the number you use when claiming the foreign tax credit. For tax year 2025, you may be able to claim the foreign tax credit without Form 1116 if your total creditable foreign taxes are $300 or less, or $600 or less if married filing jointly, all foreign-source gross income is passive category income, and all the income and foreign taxes are reported on qualified payee statements.
• The impact on after-tax yield. A 15% foreign withholding on a 4% dividend yield reduces your after-tax yield to 3.4%, before any foreign tax credit is claimed. If you do not claim the foreign tax credit, the IRS taxes the full 4% – and you lose the withheld amount permanently.
• Reference forms. Report ordinary dividends on Form 1040, line 3b, and qualified dividends on line 3a. Complete Schedule B when required, including when taxable interest or ordinary dividends exceed $1,500 or another Schedule B filing condition applies. Claim the foreign tax credit on Form 1116 or take the deduction on Schedule A.

Based on the TFX client scenario: A US expat directly owns foreign shares in a taxable brokerage account and receives $6,000 of dividends, with $900 of creditable foreign income tax withheld in the taxpayer's name. The taxpayer may claim up to $900 as a foreign tax credit, subject to the Form 1116 limitation and other eligibility rules.

By claiming the foreign tax credit on Form 1116, the expat offsets $900 in US tax, recovering the full amount.

Foreign withholding tax on interest income

Many countries impose withholding on interest paid to foreign investors, though bilateral tax treaties often reduce or eliminate this rate.

Under most US tax treaties, the withholding rate on interest drops to 0% for portfolio interest – meaning bank interest and bond interest paid to US persons from treaty countries frequently arrives without any deduction at source.

Certain types of interest paid to nonresident aliens by US institutions may be exempt under the portfolio interest rules of IRC Section 871(h).

This exemption applies to interest on most publicly traded debt obligations and bank deposit interest. The payer documents the withholding – or exemption – on Form 1042-S.

If withholding does apply, the same credit-or-deduction choice exists as with dividends. Report the gross interest on your US return and claim the foreign tax credit on Form 1116.

Foreign withholding tax on real estate transactions

Under FIRPTA – the Foreign Investment in Real Property Tax Act – the buyer of US real property from a foreign seller is the withholding agent.

The buyer can be held personally liable if the withholding tax is not remitted to the IRS.

FIRPTA requires the buyer to withhold a percentage of the gross sales price at closing and remit it to the IRS within 20 days using Form 8288.

The withholding applies when a foreign person or entity sells US real property, and the rates work as follows:

• 0% withholding – The amount realized is $300,000 or less and the buyer qualifies for the residence exception, including the required plans to use the property as a residence during each of the first two 12-month periods after the transfer.
• 10% withholding – The amount realized is more than $300,000 but not more than $1 million and the buyer qualifies for the residence reduced-rate rule.
• 15% withholding – all other dispositions of US real property interests by foreign persons – the standard FIRPTA rate since February 17, 2016.
• 21% withholding – applies to certain distributions by foreign corporations of US real property interests.

The foreign seller can apply for a withholding certificate – Form 8288-B – before closing to reduce the withholding amount if the expected US tax on the gain is less than the standard withholding.

FIRPTA withholding is not a final tax – the seller files a US tax return to report the actual gain and claim a refund of any excess withholding.

If you sell real estate abroad, the source country may impose income or capital gains tax and may require tax to be withheld at closing. A qualifying foreign income tax may be claimed on Form 1116, subject to the foreign tax credit rules and limitation.

The US expat then claims a foreign tax credit on Form 1116 for the amount withheld.

Foreign withholding tax in partnerships: What partners need to know

When a partnership earns income allocable to foreign partners, the partnership itself becomes the withholding agent.

Under IRC Section 1446, the partnership assumes primary withholding responsibility, remitting tax on effectively connected taxable income allocated to its foreign partners.

Here is how partnership withholding works:

1. The partnership calculates each foreign partner's share of effectively connected taxable income – ECTI. Only income effectively connected with a US trade or business triggers withholding – passive foreign-source income allocated to foreign partners does not.
2. The partnership withholds at the highest applicable tax rate. For noncorporate foreign partners, the rate is 37% (2025). For corporate foreign partners, the rate is 21% (2025).
3. The partnership remits withholding using Form 8813 – the partnership withholding tax payment voucher. Payments are made quarterly through EFTPS during the current calendar year – 2026 for income earned in 2026.
4. The partnership files Forms 8804 and 8805 annually. Form 8804 is the annual return of partnership withholding tax. Form 8805 is the statement issued to each foreign partner showing the withholding allocated to them.
5. Foreign partners file US returns to claim credit for over-withholding. For tax year 2025, the Section 1446 applicable percentage is generally 37% for noncorporate foreign partners and 21% for corporate foreign partners. In some cases, preferential rates or qualifying partner-level items may reduce the required withholding.

A withholding foreign partnership that fails to withhold may be liable for the unpaid tax, plus interest and penalties. The foreign partner does not escape US tax liability either – both parties can be held responsible.

Foreign withholding tax for foreign contractors and vendors

US businesses paying foreign contractors for services must determine whether backup withholding, Chapter 3 withholding, or no withholding applies.

The withholding rules depend on the contractor's tax status, where the services are performed, and whether a valid withholding certificate is on file.

• Collect a valid Form W-8BEN or W-8BEN-E before payment. A missing Form W-8 can trigger presumption and withholding rules for payments that are otherwise subject to US withholding, but compensation for services performed entirely outside the United States by a nonresident alien is generally foreign-source income and is not subject to US federal income tax withholding.
• Determine whether the income is US-source. Payments for services performed entirely outside the US are generally not subject to US withholding. The location of the service – not the contractor's address – controls sourcing.
• Issue Form 1042-S when withholding applies. If the contractor performs services in the US, the payer must withhold at 30% – or a treaty-reduced rate – and report the payment and withholding on Form 1042-S.
• Check treaty benefits. Many US tax treaties reduce or eliminate withholding on independent personal services income. The contractor must claim treaty benefits on Form 8233 for individuals or Form W-8BEN-E for entities.

Based on the TFX client scenario: A US company hires a web developer based in Canada who performs all work remotely from Toronto. Because the services are performed outside the US, no US withholding applies – but the company should still collect a Form W-8BEN to document the contractor's foreign status.

Foreign withholding tax in an IRA: Special rules and traps

Foreign withholding taxes on dividends held inside a traditional or Roth IRA cannot be recovered through the foreign tax credit because IRAs do not pay US income tax. This creates a hidden drag on returns that many investors overlook.

The foreign tax credit on Form 1116 offsets US tax on foreign-source income. But income inside a traditional IRA is tax-deferred, and income inside a Roth IRA is tax-free.

Since no US tax is owed on IRA income in the year it is earned, there is no US tax liability for the foreign withholding to offset. The withheld amount is simply lost.

The IRS does not allow a foreign tax credit for taxes paid within a tax-exempt account. Foreign dividend stocks inside an IRA face the full foreign withholding rate of the source country – often 15% to 30% – with no recovery mechanism on the US side.

 

Based on TFX client scenarios, investors who restructure their portfolios this way recover an average of several hundred dollars annually in previously lost foreign tax credits.

FATCA withholding: How it differs from standard foreign withholding

FATCA – the Foreign Account Tax Compliance Act – imposes a separate 30% withholding regime on top of the standard Chapter 3 withholding rules. The difference between the two is critical for understanding your US foreign withholding tax obligations.

• Chapter 3 withholding applies to US-source payments – dividends, interest, royalties, and other FDAP income – made to nonresident aliens and foreign entities. The standard rate is 30%, reduced by applicable tax treaties. The withholding agent reports these payments on Form 1042-S.
• Chapter 4 – FATCA – creates a separate 30% withholding regime that coordinates with Chapter 3. If a payment is subject to both regimes and Chapter 4 withholding is applied, the withholding agent generally does not also withhold the same amount under Chapter 3.
• Penalty withholding. FATCA imposes a 30% withholding rate on certain payments to non-compliant foreign financial institutions and FFIs that must register with the IRS to avoid this penalty withholding. Reference: IRS FATCA registration and Form 8966.

For individual US expats, FATCA's primary impact is the reporting requirement – Form 8938, the Statement of Specified Foreign Financial Assets – rather than withholding.

The withholding provisions mainly affect foreign institutions and the US payors who transact with them.

Unclaimed foreign tax credits could be costing you hundreds every year.

Foreign withholding tax for nonresident aliens receiving US-source income

Nonresident aliens are generally subject to a 30% US withholding rate on US-source fixed, determinable, annual, or periodical – FDAP – income such as dividends, interest, rents, and royalties.

A tax treaty between the US and the recipient's country of residence can reduce or eliminate this rate.

The recipient must file Form W-8BEN to claim the treaty-reduced rate.

Nonresident aliens who fail to submit Form W-8BEN to their US payer will be subject to the full 30% statutory withholding rate even if a lower treaty rate applies.

The withholding rules for nonresident alien wage earners follow different procedures under Section 3402, covered in the next section.

Foreign withholding tax for foreign employees working in the US

Withholding on wages paid to nonresident alien employees follows special rules under IRC Section 3402.

These rules differ from the standard payroll withholding for US citizens and residents.

• The additional flat-rate withholding amount. Nonresident alien employees are subject to an additional amount added to their wages for withholding calculation purposes. IRS Notice 1392, Supplemental Form W-4 Instructions for Nonresident Aliens, explains this rule, and the specific per-pay-period amounts are published in IRS Publication 15-T, Federal Income Tax Withholding Methods.
• Form W-4 with the nonresident alien checkbox. A nonresident alien employee subject to wage withholding should complete Form W-4 using Notice 1392 and write "Nonresident Alien" or "NRA" in the space below Step 4(c).
• Foreign government employees may have special exemptions. Employees of foreign governments working in the US may be exempt from US income tax on their official compensation under IRC Section 893. These individuals should follow special Form W-4 instructions and cannot claim the same withholding allowances as US citizen employees.
• No standard deduction for nonresident aliens. Unlike US citizens, nonresident alien employees generally cannot claim the standard deduction, which affects the withholding calculation and results in higher per-paycheck withholding.

Foreign withholding certificate: Form W-8BEN and W-8BEN-E explained

Form W-8BEN for individuals and Form W-8BEN-E for entities are the primary certificates used to establish foreign status, claim treaty benefits, and reduce US withholding rates.

These forms are generally valid for three years from the date signed and must be updated when circumstances change. A Form W-8BEN signed on March 1, 2025, expires on December 31, 2028.

An expired or missing Form W-8BEN means your withholding agent must apply the full 30% NRA withholding rate under IRC Section 1441, regardless of any treaty entitlement.

Key points about the foreign withholding tax form requirements:

• Form W-8BEN is for individuals – it certifies foreign status and claims treaty benefits for reduced withholding on dividends, interest, royalties, and other income.
• Form W-8BEN-E is for entities – foreign corporations, partnerships, trusts, and other non-individual payees use this form to certify their Chapter 3 and Chapter 4 – FATCA – status.
• Both forms require a US or foreign taxpayer identification number – TIN – to claim treaty benefits. Without a TIN, the payer cannot apply a treaty-reduced rate.

Foreign tax credit vs. deduction: Which is better for withholding taxes?

The foreign tax credit almost always provides greater tax savings than the deduction because it reduces your tax bill dollar-for-dollar rather than reducing taxable income.

Recovering withholding tax through the foreign tax credit on Form 1116 is the standard approach for most US expats.

 

Form 1116 applies separate foreign tax credit limitations by income category. Depending on your income, separate Forms 1116 may be required for passive, general, foreign branch, Section 951A, Section 901(j), treaty-resourced, and certain other categories.

This means the deduction option on Schedule A may occasionally produce a better result for taxpayers with very high foreign tax rates relative to their US rate.

 

Based on TFX client scenarios, investors who file Form 1116 consistently recover the full withholding amount within one to two tax years using the carryforward.

Form 1116 errors are one of the most common mistakes on expat returns.

Foreign withholding tax for controlled foreign corporations and PFICs

US shareholders of controlled foreign corporations – CFCs – may face withholding when the CFC distributes income.

Passive foreign investment companies – PFICs – have their own punitive tax regimes under IRC Section 1291.

The withholding rules for these entities create additional layers of complexity.

• CFC shareholders. Foreign withholding taxes paid by a CFC may be available as an indirect foreign tax credit to the US shareholder under certain conditions. The key limitation: withholding taxes paid at the fund level do not automatically flow through as a credit. A domestic corporation may qualify for deemed-paid foreign tax credits under Section 960. An individual CFC shareholder may claim a credit based on the CFC's foreign taxes in connection with Subpart F or Section 951A income when the individual makes a qualifying Section 962 election and satisfies the applicable rules.
• PFIC investors. US investors in foreign mutual funds and ETFs that qualify as PFICs face a particularly harsh treatment of foreign withholding taxes. Under the default Section 1291 rules, gains and excess distributions are subject to an interest charge and taxed at the highest ordinary rate. Foreign withholding taxes paid inside a PFIC generally cannot be credited against this tax. A QEF election or mark-to-market election may improve the result.
• Foreign withholding at the entity level. When a foreign country withholds tax on income paid to a CFC or PFIC, that tax is embedded in the entity's accounts. Whether the US shareholder can extract it as a credit depends on the specific US tax regime – Subpart F, GILTI, or Section 1291 – that applies to the income.

Owning foreign funds without proper PFIC reporting can trigger severe IRS penalties.

Foreign withholding tax recovery: How to reclaim excess withholding

Many US investors overpay foreign withholding taxes because they never submit the required treaty claim form to the foreign country, leaving refunds unclaimed for years. Here are the recovery methods:

1. Claim the foreign tax credit on Form 1116 on your US return. This is the primary recovery method for US persons. The credit offsets your US tax dollar-for-dollar, up to the limitation amount. If your foreign taxes for the year are $300 or less – $600 for married filing jointly – and all foreign income is passive and reported on qualified payee statements, you can claim the credit directly on Form 1040 without filing Form 1116.
2. File a refund claim with the foreign tax authority using the treaty relief procedure. If a foreign country withheld at a rate higher than the treaty-reduced rate – for example, 25% instead of the treaty rate of 15% – you can file a refund claim directly with that country's tax authority. Each country has its own form and deadline for reclaim requests.
3. Submit a withholding certificate before the next payment to prevent over-withholding. Filing the correct Form W-8BEN or equivalent foreign form before the income is paid ensures the correct treaty rate applies prospectively.
4. Use the IRS competent authority procedure for unresolved treaty disputes. If a foreign country refuses to honor a treaty provision, you can request the IRS competent authority to intervene under the mutual agreement procedure of the applicable tax treaty. This is a last resort for complex or high-value disputes.

Foreign withholding tax on scholarships and grants paid to nonresident aliens

Scholarship and fellowship income paid to nonresident alien students is generally subject to 14% US withholding on the taxable portion – amounts exceeding tuition and required fees. This rate applies unless a tax treaty provides a reduced rate or exemption.

The 14% rate applies to recipients on F, J, M, or Q visas. Without one of those visa types, the standard 30% rate applies.

Nonresident alien students should always check whether their home country has a treaty with the US that exempts scholarship income from withholding.

Reference IRS guidance on withholding on scholarships and Form 1042-S reporting.

The withholding agent – typically the university – is responsible for applying the correct rate and issuing Form 1042-S.

Common mistakes and how to avoid them when dealing with foreign withholding tax

Foreign withholding tax rules are complex, vary by country and income type, and mistakes can cost real money in lost credits or IRS penalties. Here are the five most common errors:

• Failing to submit Form W-8BEN before payment, triggering the full 30% withholding. This is the single most avoidable mistake. Submitting the form before the first payment ensures the treaty-reduced rate applies from the start. Filing it after the fact means pursuing a refund claim – a process that can take months or years depending on the country.
• Not claiming the foreign tax credit because the amount seems small. Even $200 to $300 in foreign withholding is worth claiming. The credit is dollar-for-dollar, and unclaimed amounts compound over years of investing. If your total creditable foreign taxes are $300 or less, or $600 or less if married filing jointly, you may claim the credit without Form 1116 only if all foreign-source gross income is passive category income, all income and taxes are reported on qualified payee statements, and the other requirements for the election are met.
• Holding foreign dividend stocks inside an IRA where the foreign tax credit is unavailable. As covered in the IRA section above, foreign withholding on IRA-held dividends is permanently lost. Restructuring your asset location between taxable and tax-advantaged accounts can recover this leakage.
• Missing the 10-year carryforward for excess foreign tax credits. If your foreign tax credit exceeds the limitation in a given year, the excess carries forward for up to 10 years. Many taxpayers lose these credits simply by not tracking them on Schedule B of Form 1116.
• Confusing FATCA withholding with standard Chapter 3 withholding. FATCA's 30% withholding applies to payments to non-compliant foreign institutions – not to individuals. If a foreign bank is withholding under FATCA, the issue is the bank's compliance status, not your personal tax position.

Based on TFX client scenarios, investors who restructure their portfolios to hold foreign stocks in taxable accounts recover an average of several hundred dollars per year in previously lost foreign tax credits.

Avoiding double taxation: How the foreign tax credit protects US expats

The purpose of the foreign withholding tax credit is to prevent double taxation – being taxed by both a foreign country and the US on the same income.

The Foreign Earned Income Exclusion addresses earned income, while the foreign tax credit on Form 1116 addresses investment and passive income subject to withholding.

For US expats, the interplay between these two provisions matters. The FEIE excludes up to $130,000 (2025) of foreign earned income from US tax, but it does not apply to dividends, interest, capital gains, or other investment income.

Those income types are where foreign withholding tax and the foreign tax credit come into play.

If you pay foreign taxes on income that is also subject to US tax, the foreign tax credit is the primary mechanism to eliminate or reduce the double hit.

The credit cannot exceed the US tax attributable to your foreign-source income – but excess credits carry forward for 10 years, giving you time to use them.

US tax obligations for expats: How foreign withholding fits the bigger picture

US citizens and green card holders owe US tax on worldwide income regardless of where they live. Foreign withholding taxes paid to other countries are not a substitute for US filing – they are a potential credit against the US tax you already owe.

The filing obligation exists even if:

• Your income was fully taxed by a foreign country.
• You have lived abroad for decades.
• You had no US-source income during the year.

Foreign withholding tax is one piece of a larger compliance picture that includes the FEIE, FBAR – FinCEN 114 – and Form 8938.

Depending on your foreign financial interests, you may also need Form 5471, Form 8865, or Form 8621.

Understanding how foreign withholding tax credits interact with these other provisions is essential to minimizing your total global tax burden.

Special situations: Foreign withholding tax on the TFSA and other foreign accounts

Canadian TFSAs – Tax-Free Savings Accounts – present a unique problem for US persons. Canada treats the TFSA as a tax-exempt account, but the IRS does not recognize the TFSA's tax-exempt status.

Investment income earned inside a TFSA – including dividends subject to foreign withholding – is taxable on the US return.

The result: a US person with a TFSA pays Canadian withholding tax on dividends inside the account and still owes US tax on the same income. Whether the foreign tax credit is available depends on the specific income type and how the TFSA is classified for US tax purposes.

In many cases, the TFSA may also trigger PFIC or foreign trust reporting requirements, adding further complexity.

Conclusion

Foreign withholding tax affects nearly every US expat with investment income, foreign business interests, or real estate transactions abroad.

The 30% default rate is not the final word – tax treaties, proper documentation, and the foreign tax credit on Form 1116 can reduce or eliminate the burden.

The most important steps: file your withholding certificates – Form W-8BEN or W-8BEN-E – before income is paid, claim the foreign tax credit on every US return, track your carryforward credits, and review your asset location between taxable and tax-advantaged accounts.

Each of these actions directly reduces the amount of foreign withholding tax you pay permanently versus temporarily.

If you are unsure whether you are overclaiming or underleveraging your foreign tax credits, or if you have missing credits from prior years, a review by an expat tax specialist can identify recoverable amounts.
