The $60,000 Estate-Tax Trap
US estate tax for non-resident aliens, explained simply
What is taxed, what is safe, and the one fund choice that fixes it
⚠️ The $60,000 Estate-Tax Trap
US citizens and US-domiciled residents enjoy a combined estate-and-gift tax exemption of $15 million in 2026. A non-domiciled non-resident alien receives only $60,000, and unlike the citizen exemption it is not adjusted for inflation. Any US-situs assets above that threshold can be taxed at rates climbing to 40%.
The reason this catches people off guard is that estate tax has nothing to do with where you live or income tax residency. It is driven by domicile and by where your assets are located. A foreign investor who has never set foot in the United States can still owe it, simply because they held US-listed shares at death.
It is also a separate tax that applies at death, not when you sell. When a non-resident dies owning US-situs assets above the threshold, the estate is required to file Form 706-NA (the US estate tax return for non-residents) within nine months. In practice, brokers and financial institutions often will not release the assets to heirs until US estate-tax clearance is shown, which can freeze an account for months.
🗂️ What Counts as a "US-Situs" Asset
Everything hinges on whether an asset is considered "US-situs" (located in the United States for estate-tax purposes). The trap is that the test follows the asset's legal location, not the underlying market it tracks.
| Asset | US-situs? | Estate tax |
|---|---|---|
| Shares of US companies (e.g. Apple, Microsoft) | Yes | Exposed |
| US-domiciled ETFs and funds (e.g. VOO, VTI) | Yes | Exposed |
| US real estate | Yes | Exposed |
| Ireland-domiciled (UCITS) ETFs holding US stocks | No | Generally outside |
| Shares of a non-US company | No | Generally outside |
The key insight: shares of a foreign corporation are not US-situs, even if that company holds substantial US assets. That single rule is what makes the fund-domicile choice in the next section so powerful.
🎯 The Three Taxes on Your US Investments
Dividend Withholding Tax
The US withholds 30% of dividends paid to non-residents by default. If your country has an income-tax treaty with the US, that rate is typically reduced, commonly to 15%. You claim the lower rate by filing a W-8BEN form with your broker.
Capital Gains Tax
Good news here: non-resident aliens are generally not subject to US capital-gains tax on the sale of publicly traded US securities, provided you are not present in the US for 183 days or more in the year. Your home country, however, may still tax the gain.
Estate Tax
The tax almost nobody plans for. At death, US-situs assets above $60,000 face estate tax at rates up to 40%, regardless of your citizenship or where you live. It is entirely separate from the dividend and capital-gains rules above.
🌍 The Fix: US-Domiciled vs Ireland-Domiciled ETFs
For most non-residents, the practical solution is the fund's domicile. Because an Ireland-domiciled UCITS fund is legally a non-US company, its shares are not US-situs, so they sit outside the US estate-tax net while still giving you exposure to the same US market.
| Feature | US-domiciled ETF | Ireland-domiciled ETF |
|---|---|---|
| US estate tax exposure | Yes (US-situs) | No (non-US-situs) |
| Dividend withholding | 15-30% to you | 15% at fund level, none to you |
| Accumulating option | Rare | Common |
| Typical expense ratio | Lower | Slightly higher |
The Irish fund still pays 15% US withholding on the US dividends it receives (under the US-Ireland treaty), but there is no second layer of withholding when it pays you, and accumulating share classes let dividends compound inside the fund. The trade-off is that Irish-domiciled funds can carry slightly higher costs, so the right choice depends on your portfolio size and whether your country has a strong US tax treaty.
📄 Can a Tax Treaty Save You?
Two different treaties matter, and people constantly confuse them. An income-tax treaty reduces dividend withholding, often to 15%. A separate estate-tax treaty can raise or even remove the $60,000 limit, but only around 15 countries have one with the US.
If your country has an estate-tax treaty (the US-UK treaty, for example, lets UK residents claim the full US exemption), your exposure may be far smaller. If it does not, the $60,000 limit stands in full. Crucially, a W-8BEN reduces only dividend withholding — it does nothing for estate tax.
🧭 Two Common Situations
If your US-situs assets stay below $60,000, the estate tax is not triggered. Many smaller investors holding US shares directly fall here. You still want a W-8BEN on file so dividends are taxed at the lower treaty rate rather than the default 30%.
Once US-situs holdings exceed $60,000 — easily reached with a single index position — estate exposure becomes real. Investors at this level commonly move to Ireland-domiciled UCITS ETFs to shift the holding outside US-situs, and check whether an estate-tax treaty applies to them.
