W-8BEN: How Expats Cut US Withholding on Dividends

US dividends default to 30% withholding for nonresident aliens. Form W-8BEN claims your treaty rate — as low as 10% — at your US broker. Here's how to file it and what rates apply.

Key Takeaways

The default US withholding rate on dividends, royalties, and rents paid to nonresident aliens is 30% under IRC §1441 — tax treaties reduce this to 10–15% at most major expat destinations.
Form W-8BEN is valid for the calendar year signed plus three succeeding years; after it expires, brokers revert to 30% withholding on the next dividend payment without notice.
US interest on registered-form bonds (Treasury bonds, corporate bonds) is withheld at 0% under the IRC §871(h) portfolio interest exemption — no treaty needed.
Japan and Mexico offer 10% treaty rates on US dividends for individual nonresident alien investors — below the 15% available from most other treaty countries.
Singapore has no income tax treaty with the United States; Singapore-resident nonresident aliens pay the full 30% statutory rate on US dividends.
REIT capital gain dividends face 21% FIRPTA withholding with no treaty reduction, but individual investors holding under 5% of a publicly traded REIT receive ordinary dividend treatment instead.

On $10,000 of US dividends, the IRS withholds $3,000 by default — 30% — before the money ever reaches a foreign account. But most nonresident aliens living in countries with US tax treaties are entitled to pay half that, or less. The mechanism is a single two-page form called Form W-8BEN. Miss it, and you overpay every quarter for as long as you hold US investments.

This guide explains how the Form W-8BEN treaty claim works, what rates apply by country, and what happens to your US interest income, dividends, and REIT distributions once you are living abroad as a nonresident alien. For context on which brokers handle this correctly, see the guide to expat dividend withholding accounts.

The Default 30% Withholding Rate

The Internal Revenue Code imposes a 30% withholding tax on Fixed, Determinable, Annual, or Periodical (FDAP) income paid to nonresident aliens by a US payor. Dividends from US corporations, royalties, rents, and certain other income all fall into this category. The rate is set by IRC §1441 and applies unless a specific exemption or treaty reduces it.

The 30% is applied to gross income — before any deductions, losses, or foreign tax credits. A broker acting as a withholding agent collects it automatically at the source and remits it to the IRS. The income recipient gets what is left. The only way to reduce the amount withheld in advance is to file Form W-8BEN claiming a treaty exemption before the payment is made.

US Interest Income: The Portfolio Interest Exemption

Not all US income faces withholding. US interest income paid to nonresident aliens is often exempt from withholding entirely under the portfolio interest exemption in IRC §871(h).

To qualify, the interest must be paid on a registered obligation (a bond or note registered to the owner in the issuer's records, as opposed to a bearer bond). US Treasury bonds, most corporate bonds, and most brokerage-held bonds are registered form. If a nonresident alien holds US Treasury bonds or investment-grade corporate bonds through a US brokerage with a valid Form W-8BEN on file, the broker withholds 0% on interest payments — no treaty required.

Exceptions that do not qualify for the portfolio interest exemption: interest paid to a holder who owns 10% or more of the voting stock of the paying corporation; contingent interest tied to the debtor's profits or revenue; and interest that is effectively connected with a US trade or business.

US bank deposit interest is separately exempt under IRC §871(i) for nonresident aliens, regardless of the portfolio interest rules. This is why a nonresident can hold cash in a US bank account and receive interest without withholding, as long as they have provided their foreign status to the bank.

Form W-8BEN: How the Treaty Claim Works

Form W-8BEN — officially, "Certificate of Foreign Status of Beneficial Owner for United States Tax Withholding and Reporting" — serves two functions. First, it establishes that the filer is not a US person, which removes them from US backup withholding under IRC §3406. Second, Part II of the form allows the filer to claim a specific treaty benefit, including a reduced withholding rate on dividends, royalties, or other income.

How to Complete and Submit the Form

Part I — Identification: Full legal name, country of citizenship, permanent address, and mailing address (if different). The address must be in the treaty country you are claiming; a US address invalidates the treaty claim.
Part II — Claim of Tax Treaty Benefits: Enter the country of residence under the treaty, cite the specific article of the treaty that applies to the income type, and state the treaty withholding rate you are claiming. For dividends from most countries, this is "Article 10" and the rate will be 15% or 10%.
Part III — Certification: Sign and date. An agent can sign on behalf of an account holder with proper authorization.
Submit to your broker: Provide the form to each withholding agent (broker, fund company, etc.) separately. One form at Schwab does not cover an account at Interactive Brokers.

Validity: A Form W-8BEN remains valid for the calendar year it is signed plus three succeeding calendar years. A form signed in September 2024 expires December 31, 2027. After expiration, the broker defaults to 30% withholding until a new form is received. Brokers are required to notify account holders before expiration, but you should track the date yourself — underpaid withholding refunds require filing Form 1040-NR.

Change in circumstances: If you move to a different country, acquire US citizenship or residency, or any other change makes the form incorrect, you must notify your withholding agent within 30 days and submit a new form.

Treaty Reduced Rates by Country

The following table shows the maximum US withholding rate on dividends available to individual nonresident aliens under each treaty. Individual investors almost always fall into the "portfolio" category — the lower "direct investment" rate requires substantial corporate ownership (10–80%+ voting interest depending on the treaty) and is rarely available to individual investors.

Country of Residence	Portfolio Dividend Rate	US Interest Withholding	Treaty Article
Canada	15%	0% (portfolio interest) or 10% treaty	Article X
United Kingdom	15%	0% (portfolio interest)	Article 10
Germany	15%	0% (portfolio interest)	Article 10
France	15%	0% (portfolio interest)	Article 10
Netherlands	15%	0% (portfolio interest)	Article 10
Japan	10%	0% (portfolio interest)	Article 10
Australia	15%	0% (portfolio interest)	Article 10
Mexico	10%	0% (portfolio interest)	Article 10
Ireland	15%	0% (portfolio interest)	Article 10
Singapore	30% — no treaty	0% (portfolio interest)	No US treaty in force
No treaty country	30% statutory rate	0% (portfolio interest)	N/A

Rates verified as of June 2026 against IRS Tax Treaty Tables (irs.gov/individuals/international-taxpayers/tax-treaty-tables) and individual treaty PDFs published at irs.gov. Singapore has no income tax treaty with the United States. Rates can change if a treaty is renegotiated.

For most major expat destinations covered in the US tax treaty savings clause guide, the portfolio dividend withholding rate is 15% — half the statutory rate. Japan and Mexico are notable exceptions where the rate falls to 10% for individual investors.

Why US Citizens Cannot Use This

Nearly every US income tax treaty contains a savings clause — usually in Article 1 — that preserves the US's right to tax its own citizens and residents as if the treaty did not exist. The IRS states this explicitly: "Tax treaties reduce the U.S. income taxes of residents of foreign countries. With certain exceptions, they do not reduce the U.S. income taxes of U.S. citizens or U.S. residents."

A US citizen living in Germany cannot claim the US-Germany 15% treaty rate on US dividends. They are subject to full US tax on those dividends just as they would be if they lived in the United States. The savings clause is why the W-8BEN path is only available to nonresident aliens — former citizens who have renounced, former green card holders who have formally abandoned status, and foreign nationals who were never US tax residents.

REIT Dividends for Nonresident Aliens

US Real Estate Investment Trusts (REITs) pay dividends that fall into three separate categories for nonresident alien investors, each with different withholding treatment.

Ordinary REIT dividends are treated as standard FDAP income. The 30% rate applies by default, reduced to the treaty rate (typically 15%) if you have filed a W-8BEN with a treaty claim. These are the distributions you receive quarterly from most publicly traded REITs and are reported on Form 1042-S.

REIT capital gain dividends (distributions that the REIT designates as arising from gains on property sales) are subject to FIRPTA — the Foreign Investment in Real Property Tax Act — under IRC §897(h). The FIRPTA withholding rate on these distributions is 21%, and no tax treaty reduces it. The full 21% applies to the gross capital gain distribution regardless of treaty status.

The publicly traded exception: If the REIT's shares are regularly traded on a recognized US stock exchange and you hold 5% or less of the REIT's outstanding shares, the capital gain dividend is treated as an ordinary dividend rather than FIRPTA income. In practice, virtually all individual nonresident alien investors who hold US REIT shares through a brokerage account will own less than 5% and therefore receive the ordinary dividend treatment on capital gain distributions — meaning the treaty rate applies instead of 21% FIRPTA withholding.

Form 1042-S: What You Receive Each Year

Each US withholding agent that pays FDAP income to a nonresident alien must issue Form 1042-S, "Foreign Person's U.S. Source Income Subject to Withholding," by March 15 of the following year. This is the NRA's equivalent of a 1099 — it shows gross income paid, the income code, and the amount withheld at source.

If you filed W-8BEN and your broker applied the treaty rate, the 1042-S will show the treaty-reduced rate in Box 3b (Chapter 3 tax rate). If no W-8BEN was on file and the full 30% was withheld, the form will show 30%. If the amount withheld was higher than the correct treaty rate, you can file Form 1040-NR (US Nonresident Alien Income Tax Return) to claim a refund of the excess — but you cannot reclaim amounts withheld in prior years without amending those returns, so keeping W-8BEN current matters.

How Major Brokers Apply Treaty Rates

Charles Schwab and Interactive Brokers both act as withholding agents and apply the reduced treaty rate automatically once a valid Form W-8BEN with a treaty claim is on file. You do not need to request the reduction on a payment-by-payment basis. The key risks are form expiration and account changes. If your W-8BEN expires and you do not renew it in time, the broker reverts to 30% withholding on the next dividend payment — usually with no grace period.

W-8BEN Compliance Checklist

Confirm you are a nonresident alien (not a US citizen, US national, or green card holder)
Identify your country of residence for treaty purposes — this must be a country with a US income tax treaty in force
Locate the applicable treaty article for each income type (dividends: almost always Article 10)
Complete Part I (identification) and Part II (treaty claim) of Form W-8BEN
Submit to each withholding agent separately before the first income payment
Track the expiration date (December 31 of the third succeeding calendar year)
Update the form within 30 days if your country of residence changes
Reconcile Form 1042-S against your brokerage statements each March
File Form 1040-NR if you need to claim a refund of excess withholding

Chapter 3 vs. Chapter 4: NRA Withholding vs. FATCA

Two separate withholding systems operate on payments to foreign persons. Chapter 3 of the IRC (§§1441–1443) covers traditional NRA withholding on FDAP income — the 30% or treaty-reduced rate described above. Chapter 4 (§§1471–1474) is FATCA, which imposes 30% withholding on "withholdable payments" to foreign financial institutions that have not registered with the IRS and agreed to report their US account holders.

The Chapter 4 FATCA withholding rate is also 30%, but it is not reduced by tax treaties — no treaty claim on a W-8BEN reduces FATCA withholding. As an individual nonresident alien investor with accounts at registered foreign financial institutions, Chapter 4 withholding generally should not apply to you because most major foreign banks and brokers are registered FATCA-compliant foreign financial institutions. The W-8BEN you file establishes your status under both Chapter 3 and Chapter 4 frameworks simultaneously.

Conclusion

The difference between filing Form W-8BEN and not filing it is straightforward: on $50,000 in US dividends per year, the gap between 30% withholding and 15% withholding is $7,500 annually. Over a decade with compound growth, that gap compounds further. The form is short, free, and requires nothing from the IRS — just your signature and your broker's receipt.

The catch is that it requires you to actually be a nonresident alien, have a country of residence covered by a US treaty, and keep the form current. US citizens living abroad cannot use it. Former citizens who have renounced and former green card holders who have formally terminated their LPR status can — and generally should — file it with every US broker where they hold dividend-paying assets.

The portfolio interest exemption provides equally valuable relief on US bond income — typically 0% withholding — without even needing a treaty. For nonresident aliens building a diversified US portfolio from abroad, the combination of the interest exemption and treaty-reduced dividend rates dramatically changes the after-tax return profile of US assets.

Frequently asked questions

What is Form W-8BEN and who needs to file it?

Form W-8BEN is a certificate of foreign status filed by individual nonresident aliens with US withholding agents such as brokers. It establishes that the filer is not a US person and, in Part II, allows the filer to claim a reduced withholding rate under an applicable tax treaty. Every nonresident alien holding dividend-paying US investments should file one with each broker before the first payment to avoid the default 30% withholding rate.

How long is Form W-8BEN valid before it needs to be renewed?

Form W-8BEN is valid for the calendar year it is signed plus the three succeeding calendar years. A form signed on any date in 2024 expires December 31, 2027. After expiration, the broker must apply the 30% statutory withholding rate to future payments until a new, signed form is received. There is typically no automatic grace period.

Can I get a refund if my US broker withheld too much tax?

Yes. If a US withholding agent applied the 30% statutory rate instead of your correct treaty rate, you can file Form 1040-NR (US Nonresident Alien Income Tax Return) to claim a refund of the excess withholding. The Form 1042-S issued by your broker by March 15 shows the income received and the amount withheld, and serves as your primary documentation for the refund claim.

Does US interest income face the 30% withholding rate for nonresident aliens?

No. Most US interest income paid to nonresident aliens qualifies for the portfolio interest exemption under IRC §871(h) and is withheld at 0% — no treaty required. US Treasury bonds, corporate bonds in registered form, and most other registered obligations qualify. Bank deposit interest is separately exempt under IRC §871(i). Exceptions include interest paid to a 10%-or-more shareholder and contingent interest tied to debtor profits.
