A foreign investor can receive a dividend from a U.S. company and lose part of it to U.S. withholding tax, then receive interest from a U.S. Treasury security with no U.S. federal income tax at all.
At first glance, that seems inconsistent. Both investments are American. Both may sit in the same brokerage account. Yet the tax treatment can be completely different.
The reason is that U.S. tax law cares about what kind of income you received, not simply where your brokerage account is located.
For a nonresident alien, certain U.S. bank-deposit interest and qualifying portfolio interest can be excluded from U.S. federal income tax when the statutory requirements are met and the income is not effectively connected with a U.S. trade or business.
That can make Treasury securities, bank CDs, and certain bonds unusually attractive from a U.S. tax perspective.
But there are three qualifications worth putting up front.
“Foreign investor” is not the tax status that matters. The favorable rules discussed here generally concern nonresident aliens. A foreign citizen who is a U.S. resident alien is generally taxed much more like a U.S. citizen.
Second, “0% U.S. tax” does not mean the income is tax-free everywhere. Your country of tax residence may tax the same interest.
And third, a Treasury bond, a Treasury ETF, a bank CD, and a corporate bond may look similar in a portfolio but do not necessarily produce the same U.S. tax result.
Quick answer for a nonresident alien investor
A qualifying individual Treasury obligation may generate portfolio interest exempt from U.S. federal income tax. Interest on a qualifying U.S. bank CD can be excluded under a separate deposit-interest rule. A U.S.-domiciled Treasury ETF, however, distributes fund income that must be classified separately.
These outcomes depend on the investor’s U.S. tax residency, income characterization, non-ECI status, documentation and other exceptions. Neither exclusion decides the investor’s home-country tax.
Last reviewed: October 17, 2026. This guide addresses U.S. federal tax rules for individual nonresident aliens. Home-country taxation and treaty treatment must be considered separately.
Why interest can receive better treatment than dividends
Start with the contrast most investors notice first.
A U.S.-source corporate dividend paid to a nonresident alien is generally subject to a 30% statutory withholding rate unless an income-tax treaty or another rule reduces it.
Interest is more complicated — and often more favorable.
The Internal Revenue Code contains separate exclusions for certain deposit interest and portfolio interest. When an NRA satisfies those rules and the income is not effectively connected with a U.S. trade or business, the United States generally does not impose federal income tax on that interest.
That is why the same investor might see:
| Investment income | Typical U.S. treatment for an NRA | What matters |
|---|---|---|
| U.S. stock dividend | 30% statutory withholding, potentially reduced by treaty | Treaty residence and dividend article |
| U.S. bank deposit or qualifying bank CD interest | Generally excluded from U.S. federal income tax if the deposit-interest rules apply and it is not ECI | Type of deposit and connection to a U.S. trade or business |
| Qualifying Treasury or other portfolio interest | Generally exempt from Chapter 3 withholding | Portfolio-interest requirements and documentation |
| Corporate bond interest | Often qualifies, but not automatically | Registered obligation, ownership, contingent-interest and other exceptions |
| U.S. bond or Treasury ETF distribution | Depends on how the fund characterizes and designates the distribution | Fund distribution classification |
That last row is particularly important. Buying a Treasury ETF is not tax-identical to owning a Treasury security directly.
Bank CDs are covered by a different rule from Treasury bonds
It is tempting to say that Treasuries and CDs are both tax-free because they are “interest.” Technically, they get there by different routes.
IRS Publication 515 says foreign persons are generally not subject to Chapter 3 withholding on qualifying interest from deposits with businesses such as U.S. banks when that interest is not connected with a U.S. trade or business.
The IRS definition of deposits for this purpose expressly includes certificates of deposit, along with open-account time deposits and other qualifying deposit arrangements.
That makes a conventional CD issued by a qualifying banking institution very different from a corporate dividend.
There is still a practical question to ask before assuming a product qualifies:
Is it actually a bank deposit?
A brokerage platform can show several cash-like products next to one another — brokered CDs, money-market funds, Treasury securities, sweep arrangements and other instruments. They may all look like “cash earning interest” on the screen, but the legal form of the product determines the tax treatment.
A money-market fund, for example, is a fund. It is not simply a bank deposit because its yield looks similar to a savings account.
Before buying a CD: confirm the issuer and the protection
The word CD in a brokerage account does not tell you everything about how the investment works. A brokered CD issued by an FDIC-insured U.S. bank is still a bank deposit for insurance purposes if the applicable pass-through requirements are met; a corporate note, bond fund or money-market mutual fund is not automatically a bank deposit.
FDIC’s standard deposit insurance limit is $250,000 per depositor, per FDIC-insured bank, per ownership category. Deposits held directly and through a broker at the same insured bank may have to be aggregated. FDIC insurance addresses covered bank failures — it does not protect against a loss if a brokered CD is sold early at a lower market price.
A U.S. Treasury bill, note or bond is not FDIC insured. Treasury obligations are instead backed by the full faith and credit of the U.S. government. A Treasury ETF is a fund investment, not a direct Treasury debt claim or an FDIC-insured bank account.
| What you own | Primary protection or risk | Before you proceed |
|---|---|---|
| Individual U.S. Treasury | U.S. government credit; market-price risk if sold early | Can your brokerage hold this maturity? |
| Bank-issued CD | Eligible FDIC deposit insurance; possible early-sale loss | Check issuing bank and combined deposits |
| U.S. Treasury ETF | Fund NAV, trading spread and distribution classification | Check annual tax designation and fund domicile |
Sources: FDIC, Your Insured Deposits and SEC, Brokered CDs Investor Bulletin. Investor eligibility, deposit insurance and U.S. income tax are separate tests.
Why Treasury securities can qualify for the portfolio-interest exemption
Treasury securities generally fit into the other major interest exclusion: portfolio interest.
IRS guidance excludes qualifying portfolio interest on covered obligations issued after July 18, 1984. Modern marketable Treasury securities and many other registered debt obligations can fall within that framework when the requirements are satisfied.
For an ordinary foreign individual holding Treasury bills, notes, or bonds as an investment, that can mean no U.S. federal income tax on qualifying interest.
This is not a treaty benefit in the ordinary sense.
That distinction matters because an investor from a country with no U.S. income-tax treaty can still potentially qualify for the statutory portfolio-interest exemption.
In other words, you should not think of the rule as:
“My country negotiated a 0% Treasury rate.”
A better way to think about it is:
U.S. domestic tax law itself excludes certain portfolio interest received by foreign investors.
What about a Treasury bill that pays no coupon?
Treasury bills are commonly issued at a discount and redeemed at face value. The Treasury describes the difference between the purchase price and the redemption amount as interest. For instance, if a bill costs $9,800 and pays $10,000 at maturity, the discount earned is $200. This is an illustration of the payment mechanics, not a current Treasury bill quote.
Do not assume that selling a Treasury security before maturity and realizing a trading gain is the same tax event as receiving stated interest or the bill’s issue discount. Original-issue discount, market discount, sale proceeds and capital gains can be subject to different tax characterization and reporting rules. The examples below concern qualifying interest or qualifying fund distributions, not gains on an early sale.
Sources: TreasuryDirect, Understanding Pricing and IRS Publication 515.
Not every corporate bond automatically gets the same 0% result
Portfolio interest is broad, but it is not unlimited.
IRS Publication 515 lists situations in which interest does not qualify.
One example involves a foreign investor who owns at least 10% of the voting power of a corporate borrower. Interest on that company’s debt generally does not qualify for the portfolio-interest exemption under the ordinary 10%-owner rule.
Certain contingent interest can also fall outside the exemption — for example, interest whose amount depends on the debtor’s revenue, profit, property value, dividends, or similar measures.
There are additional rules for banks, controlled foreign corporations and other specialized situations.
For someone buying a conventional widely traded bond as a small portfolio investor, these exceptions may never become relevant. But they are the reason a professional explanation should say “qualifying portfolio interest” rather than “all U.S. bond interest is tax-free.”
A Treasury ETF is not the same tax asset as a Treasury note
This is probably the most useful distinction for an investor choosing how to hold fixed income.
Suppose you want exposure to short-term U.S. Treasury securities.
You could buy an individual Treasury security. Or you could buy shares of a U.S.-domiciled ETF that owns Treasury securities.
Economically, the two portfolios may behave similarly.
Legally, you own something different.
With the first, you own debt of the U.S. government.
With the second, you own shares of an investment company that owns the debt.
IRS Publication 515 allows certain regulated investment companies to designate distributions as interest-related dividends, and those qualifying distributions can be exempt from Chapter 3 withholding.
But that does not mean every dollar distributed by every Treasury or bond ETF automatically receives the portfolio-interest exemption.
The fund’s own tax reporting and characterization matter.
Do not assume that “the ETF owns Treasuries” means “every ETF distribution is automatically tax-free to an NRA.” Direct debt interest and a distribution from a fund are legally different payments.
This is worth checking on the fund’s annual tax information if withholding efficiency is an important part of your investment decision.
Worked comparison: $10,000 at a hypothetical 4% cash yield
Here is the question a real investor needs answered: if three investments each generate $400 before U.S. tax, how much might the investor actually receive?
Assume an individual is a nonresident alien for U.S. federal income-tax purposes, holds the investments outside a U.S. trade or business, has supplied valid foreign-status documentation, and does not have other factors changing the default results. Assume the $10,000 investment produces $400 of annual gross income (a fictional 4% return, not a quoted market yield). For the ETF scenarios, assume the entire $400 is paid as a distribution, no treaty reduces withholding, and ignore trading costs and home-country tax.
| Illustrative case | Gross income | U.S. tax withheld | Cash after U.S. withholding |
|---|---|---|---|
| Direct qualifying Treasury interest | $400 | $0 | $400 |
| Qualifying U.S. bank-CD interest | $400 | $0 | $400 |
| ETF distribution: all designated eligible interest-related dividends | $400 | $0 | $400 |
| ETF distribution: all ordinary dividends subject to unreduced 30% withholding | $400 | $120 | $280 |
What is the $120 difference? It is $400 × 30%, but only in the specific example where the entire ETF distribution is treated as ordinary U.S.-source dividends subject to the unreduced statutory rate. It is not a claim that Treasury ETFs ordinarily lose 30% or that every fund designates 100% of distributions as interest-related dividends. Actual distributions can contain different classifications, and treaty provisions, taxpayer status and Chapter 4 rules can change treatment.
To apply the comparison to a particular fund, check that fund’s year-specific tax information for non-U.S. shareholders, not just the ETF name or its underlying holdings. IRS Publication 519 explains that a regulated investment company must designate eligible interest-related dividends in writing.
Calculation you can reuse: gross distribution × taxable share × applicable withholding rate = illustrative U.S. withholding. The taxable share is determined by the fund’s classification and the investor’s tax circumstances; it is not something you can infer from the fund’s name.
One practical obstacle: TreasuryDirect is not designed for a typical overseas NRA
Knowing that Treasury interest can receive favorable U.S. tax treatment raises the next obvious question: why not simply open TreasuryDirect and buy directly from the U.S. government?
For many overseas investors, that is not an available route.
TreasuryDirect’s current account requirements state that an individual opening an account must be a U.S. person and have a valid U.S. Social Security number, a U.S. address of record, and an account at a U.S. depository financial institution capable of ACH transactions.
So there is an important distinction between:
being legally able to own a U.S. Treasury security
and
being eligible to open a TreasuryDirect account.
A nonresident investor living abroad will therefore commonly need to look at a brokerage that serves the investor’s country and provides access to marketable U.S. Treasury securities.
Our brokerage guide for non-residents and visa holders explains why country-of-residence eligibility needs to be checked before choosing the investment itself.

W-8BEN still matters even when the U.S. tax rate is zero
An exemption does not mean documentation becomes irrelevant.
Your financial institution needs to know that you are a foreign person and, where relevant, that the payment qualifies for foreign-person withholding treatment.
That is one reason an NRA investor will commonly be asked to maintain a valid Form W-8BEN.
For bank deposits, providing appropriate foreign-status documentation helps the institution distinguish an NRA account from an account belonging to a U.S. person.
For portfolio interest, documentation of foreign status is part of the withholding framework.
If your status later changes — for example, you become a resident alien for U.S. tax purposes — you should not continue assuming that the NRA interest exclusions apply simply because the same securities remain in the same brokerage account.
For the form itself, see our W-8BEN guide for foreign investors.
Zero tax does not always mean zero reporting
This is another place where the current KoruVest article needed a correction.
It is too broad to say that U.S. bank or CD interest received by an NRA is “not even reported.”
In many ordinary cases, deposit interest can be nontaxable and may not be subject to the same reporting regime that applies to taxable interest. But the IRS also requires Form 1042-S information reporting for certain U.S. deposit interest of $10 or more paid to nonresident individuals resident in specified countries with which tax-information exchange arrangements apply. That reporting does not, by itself, make the interest taxable.
Portfolio interest presents another example: the IRS states that qualifying portfolio interest received by an NRA can be nontaxable while still being reported on Form 1042-S.
That distinction is worth remembering:
Taxable, withheld, and reportable are three different questions. An item of income can be reportable even when the U.S. tax due on it is zero.
The estate-tax difference can be just as important as the income-tax difference
For a large foreign portfolio, the story does not end with annual interest.
Nonresident noncitizens can also face U.S. estate-tax rules on certain U.S.-situated assets. The general Form 706-NA filing threshold is only $60,000 of relevant U.S.-situated assets and specified prior transfers.
The $60,000 figure is generally a filing threshold, not a flat $60,000 tax bill or an automatic $60,000 taxable gain. It concerns the estate of a nonresident not a citizen under estate-tax rules, which are based on domicile and can differ from the residency test used for annual U.S. income tax. Filing and actual tax liability must be assessed separately, including possible treaty provisions.
Two hypothetical $65,000 holdings at death
Case A — $65,000 in U.S. corporation shares: ordinarily U.S.-situs property for a nonresident noncitizen estate, potentially creating Form 706-NA filing obligations, subject to treaties and other facts.
Case B — $65,000 in qualifying direct portfolio-interest debt: the debt may be excluded from U.S. situs under the statutory rules. The result depends on the actual instrument and facts; an ETF holding such debt does not automatically get the same treatment.
But U.S. law contains important situs exceptions for certain debt and deposit assets.
The current Form 706-NA instructions state that a debt obligation issued after July 18, 1984 can generally be treated as property located outside the United States if the interest would have qualified for the portfolio-interest exemption when received by the decedent.
The instructions also treat qualifying deposits with a U.S. bank and certain similar institutions as located outside the United States when they are not effectively connected with a U.S. trade or business.
Compare that with stock.
Shares of corporations organized under U.S. law are generally treated as U.S.-situated property for an NRNC estate.
That creates a potentially important distinction between:
- holding a qualifying Treasury debt obligation directly;
- holding a qualifying bank deposit or CD; and
- holding shares of a U.S.-domiciled investment fund.
The third item should not simply be assumed to inherit the estate-tax situs of the bonds held inside the fund.
Why this matters for larger portfolios
Two investments can give you nearly identical Treasury exposure during your lifetime while producing different estate-tax questions at death. Once a cross-border U.S. portfolio becomes substantial, asset structure matters — not just yield and expense ratio.
Estate-tax treaties can change the result, and individual circumstances matter. This is an area where professional cross-border estate advice becomes worthwhile as balances grow.
What about your home country’s tax?
A U.S. exemption does not turn an investment into a globally tax-free asset.
If you live in South Korea, Japan, Canada, India, Europe, or elsewhere, your country of tax residence may tax interest from foreign bonds, Treasury securities, CDs, or bank accounts under its own rules.
It may also impose reporting requirements on foreign accounts or financial assets.
So when comparing a U.S. Treasury with an investment available at home, do not compare only the headline yields.
A more useful comparison is:
after-tax return in both countries + currency risk + investment risk + account costs.
A Treasury paying a higher dollar yield can still produce a disappointing home-currency return if the dollar falls sharply against your own currency. Conversely, currency appreciation can add to the return.
What a 5% exchange-rate move does to a 4% dollar return
For a South Korean or other overseas investor, the last line of the return calculation belongs in the home currency. A U.S. investment that earns 4% in dollars does not necessarily earn 4% when translated back.
Take an illustrative $10,000 beginning value and $400 of dollar income, with no U.S. withholding, no home-country taxes and no conversion costs. If the U.S. dollar falls 5% against the investor’s home currency during the period, the translated ending value is 1.04 × 0.95 = 0.988 times the beginning value — a 1.2% home-currency loss. If the dollar instead rises 5%, the home-currency return would be 1.04 × 1.05 − 1 = 9.2%.
These are mathematical scenarios, not exchange-rate forecasts. They show why a tax-efficient 4% U.S. dollar return can still be a poor choice for an investor who needs to spend the money soon in another currency.
How the choices differ in practice
For an NRA investor, the four products below can all look like “safe dollar income.” They solve different problems.
| Product | U.S. tax question | Practical issue |
|---|---|---|
| Individual Treasury bill/note/bond | Can qualify for portfolio-interest treatment | Need a brokerage accessible from your country; TreasuryDirect may not be available |
| Bank CD | Qualifying deposit interest can be exempt | Issuer, maturity, early-withdrawal terms and account eligibility |
| Corporate bond | May qualify as portfolio interest | Credit risk plus portfolio-interest exceptions |
| Treasury/bond ETF | Fund distributions require separate characterization | Simple trading and diversification, but not legally identical to direct bonds |
The questions I would check before buying
For a foreign investor, the tax analysis does not need to begin with a stack of IRS forms. Start with the investment itself.
What exactly am I buying? A bank deposit, an individual bond, or shares of a fund?
Am I still a nonresident alien for U.S. tax purposes? Citizenship alone does not answer that question.
Will the payment qualify as deposit interest or portfolio interest?
Does my broker have a valid W-8BEN on file?
If this is a bond fund, how does the fund characterize distributions to foreign shareholders?
How will my country of residence tax the income?
And if the U.S. portfolio is becoming large:
Does direct ownership versus fund ownership change my U.S. estate-tax exposure?
Those questions are more useful than simply asking whether “Treasuries are tax-free for foreigners.”

Frequently asked questions
Do nonresident aliens pay U.S. tax on Treasury interest?
Qualifying interest on Treasury securities can generally fall within the portfolio-interest exemption for a nonresident alien when the statutory and documentation requirements are satisfied and the income is not effectively connected with a U.S. trade or business.
Do nonresident aliens pay U.S. tax on bank CDs?
Interest on qualifying deposits with U.S. banking institutions is generally excluded from U.S. federal income tax for an NRA when it is not effectively connected with a U.S. trade or business. IRS Publication 515 expressly includes certificates of deposit within the relevant deposit category.
Does a foreign investor need a tax treaty to get 0% on Treasury interest?
Not necessarily. The portfolio-interest exemption is a provision of U.S. domestic tax law. A treaty can matter in other interest situations, but the statutory portfolio-interest exclusion does not exist only for residents of treaty countries.
Can a nonresident alien open a TreasuryDirect account?
A typical overseas NRA generally will not satisfy TreasuryDirect’s current individual-account requirements. TreasuryDirect requires the account holder to be a U.S. person and also requires items including a valid U.S. Social Security number, U.S. address of record and qualifying U.S. bank account.
Is a Treasury ETF tax-free for a nonresident alien?
Do not assume so merely because the fund owns Treasury securities. Certain interest-related dividends designated by a U.S. mutual fund or other regulated investment company can be exempt from Chapter 3 withholding, but fund distributions must be analyzed according to their own tax characterization.
Is interest from every U.S. corporate bond tax-free?
No. Many conventional obligations can qualify for the portfolio-interest exemption, but exceptions include certain contingent interest and interest paid to specified 10% owners, among other situations.
If the U.S. tax is zero, will I receive no tax form?
Not necessarily. Taxability and information reporting are different. Qualifying portfolio interest can be nontaxable while still being reported on Form 1042-S, and special reporting rules also apply to certain deposit interest.
Are Treasuries better than U.S. stocks for estate tax?
They can present a very different estate-tax profile for a nonresident noncitizen. Qualifying portfolio debt can generally be treated as situated outside the United States under the Form 706-NA rules, while shares of U.S. corporations are generally U.S.-situated property. Fund ownership and treaty rules require separate analysis.
