Every article on this site about buying US stocks focuses on income tax - dividend withholding, capital gains treatment, treaty rates. Estate tax is a genuinely different, and often overlooked, exposure: if you die owning US-situs assets above a very low threshold, your estate can owe US federal estate tax at rates up to 40% - regardless of your citizenship, regardless of where you live, and regardless of how small your worldwide estate actually is.
The Exemption Gap That Catches People Off Guard
US citizens and domiciliaries receive an estate tax exemption of $15 million per individual for 2026, indexed going forward under the One Big Beautiful Bill Act. Non-resident aliens receive a $60,000 exemption on US-situs assets - a figure that is not indexed for inflation and has remained fixed for decades. This is not a rounding difference from the citizen exemption; it is a categorically different, dramatically smaller threshold, roughly two orders of magnitude apart from the citizen figure.
What this means concretely: a non-US investor with a $200,000 US brokerage account - not an unusual amount for someone who has been investing steadily for a decade or more, as covered throughout this site’s strategies content - has $140,000 exposed above the exemption, taxed at graduated rates that reach 40% on the amount above the threshold. This is a real, calculable liability, not a hypothetical concern for only the wealthiest investors.
A Worked Calculation
The NRA estate tax rate schedule is graduated, running from 18% to a 40% top rate - but the way the exemption is delivered means you never actually pay the bottom brackets.
There is no $60,000 deduction as such. IRC §2102(b) gives a unified credit of $13,000, and $13,000 is precisely the tentative tax on $60,000 under the §2001(c) schedule. The credit therefore consumes the 18%, 20%, 22% and 24% bands in full. The first taxable dollar above $60,000 is taxed at 26%, not 18% - a distinction that matters, because 18% is the figure most summaries quote.
Worked properly, for an investor whose US-situs assets total $260,000 at death:
| Step | Amount |
|---|---|
| Gross US-situs estate | $260,000 |
| Tentative tax on $260,000 (§2001(c) schedule) | $74,200 |
| Less §2102(b) unified credit | −$13,000 |
| Estate tax due | $61,200 |
That is 30.6% of the $200,000 above the exemption - well under the 40% headline, but nowhere near the 18% the bottom of the schedule suggests.
A smaller estate shows the same shape. On $150,000 of US-situs assets, the tentative tax is $38,800, less the $13,000 credit leaves $25,800 - 28.7% of the $90,000 taxable amount. The effective rate grows larger as the taxable amount grows - the same graduated-bracket logic that applies to US income tax, applied here to the estate tax calculation instead.
Why this matters for planning purposes: understanding that the tax is graduated, not a flat 40% on everything above $60,000, changes the urgency calculus somewhat for a moderate-sized portfolio - a $150,000 US-situs position facing a $90,000 taxable amount owes meaningfully less than 40% of that $90,000 in practice, even though the top rate does apply once the taxable amount grows large enough to reach the highest bracket.
What Counts as US-Situs
US-listed stocks and securities held through any broker - including a foreign broker - generally count as US-situs assets for this purpose. Moving your holdings to a non-US brokerage platform does not change the situs of US-listed securities; the tax exposure follows the underlying asset’s US character, not the location of the account holding it.
This is a common and understandable point of confusion - it seems intuitive that a European or Asian brokerage account should be outside US estate tax’s reach, but the determining factor is what the account holds (US-listed securities), not where the account itself is domiciled. Non-US-domiciled funds - UCITS ETFs, for instance - are generally treated differently, since the fund itself is not a US entity, a genuine mitigation angle covered in more depth in our UCITS vs US-domiciled comparison and in our companion avoiding US estate tax guide.
Filing Requirements
If a non-resident alien’s US-situs assets exceed the $60,000 threshold at death, the estate’s executor is required to file Form 706-NA with the IRS, reporting the US-situs assets and calculating any tax owed. This filing obligation exists independent of whether the deceased ever filed a US income tax return during their lifetime - it is triggered by the value of US assets at death, not by any prior US tax filing history, which means an investor who never filed a 1040-NR while alive (because their income-side obligations were fully satisfied through broker withholding) can still generate a Form 706-NA filing obligation for their estate.
Who is actually responsible for this filing is worth naming directly: the estate’s executor or personal representative, a role that in practice often falls to a family member unfamiliar with US tax filing requirements, adding real practical difficulty on top of the tax liability itself, particularly when the executor lives outside the US and has no existing relationship with a US tax professional.
Why This Threshold Matters More Than Most Investors Realize
The $60,000 figure is genuinely easy to exceed. Unlike income tax withholding, which is a percentage that scales naturally with a modest portfolio, this is a fixed-dollar threshold that a meaningfully sized long-term investment portfolio - the exact kind this site encourages building through steady, disciplined investing - can cross without the investor necessarily realizing the estate tax implications changed as the portfolio grew from a modest starting amount into six figures over years of consistent contributions.
This is not primarily a “wealthy investor” problem. An investor who has been contributing regularly to a US brokerage account for retirement savings, following the strategies covered throughout this site, can reach six-figure US-situs exposure well before reaching a level of wealth where estate planning typically enters the conversation in a general sense - which is exactly why this guide exists as a distinct category on this site rather than being treated as a niche concern for high-net-worth investors only.
Frequently Asked Questions
Does the $60,000 exemption apply per person, or per couple/family? Per person - each non-resident alien individual has their own separate $60,000 exemption; there’s no combined or portable exemption between spouses the way US citizen spouses can access certain marital deduction provisions, a distinction covered in more detail in our joint accounts guide.
Does the $60,000 threshold ever get adjusted, or has it truly never changed? The figure has remained fixed for a long period without inflation indexing, unlike many other tax thresholds that adjust periodically - while tax law can always change through future legislation, this specific figure’s history of remaining static is itself part of why it catches investors off guard, since a portfolio that felt modest years ago may have grown well past a threshold that never moved.
If my worldwide estate is well below any country’s typical estate tax threshold, does the US $60,000 exemption still apply? Yes - the US NRA estate tax exemption is based specifically on US-situs asset value, entirely independent of your total worldwide estate size or your home country’s own estate tax rules and thresholds. A modest worldwide estate with a meaningful US-situs component can still generate US estate tax exposure even if the same investor’s home country would never tax an estate of that total size.
Is there any way to reduce this exposure without giving up US stock exposure entirely? Yes - several structural approaches exist, covered throughout this category, including holding through non-US-domiciled funds, specific account structuring, and treaty-based relief for investors from certain countries, covered in our avoiding US estate tax guide and estate tax treaty countries guide.
Working Through US Estate Tax for Non-Resident Aliens Step by Step
- Estimate your current US-situs asset value (US-listed stocks and ETFs, regardless of which broker holds them) against the $60,000 threshold
- Do not assume moving your account to a non-US broker changes your US estate tax exposure - it generally does not, for US-listed securities specifically
- Understand the graduated rate structure - the tax isn’t a flat 40% on your entire taxable amount, though larger taxable amounts do approach that top rate
- If your US-situs assets exceed or are approaching $60,000, treat this as a genuine planning item, not a distant concern
- Confirm your executor or personal representative understands the Form 706-NA filing obligation, since it exists independent of the deceased’s income tax filing history
- Explore mitigation approaches (non-US-domiciled funds, treaty relief, account structuring) covered elsewhere in this category
The Short Version of US Estate Tax for Non-Resident Aliens
The $60,000 non-resident alien estate tax exemption is dramatically smaller than most international investors assume, is not adjusted for inflation, and applies regardless of where your brokerage account is held - only what it holds. For any investor building a meaningful long-term US stock position, this is worth understanding and planning around well before it becomes an urgent concern, not treated as a footnote, given how easily a steadily growing portfolio can cross this fixed, decades-old threshold.
None of this is advice on US Estate Tax for Non-Resident Aliens for your specific situation. US estate tax rules, exemption amounts, and rates are set by federal law and can change. Your position deserves a professional’s review before you commit.
