Estate Tax Situs Risk for Non-Resident Aliens
The Formal Definition
A statutory estate tax liability under Internal Revenue Code Section 2101 where foreign non-resident alien (NRA) individuals holding direct 'US-situs assets' (including shares of US corporations) are assessed federal estate taxes up to 40% on account values exceeding a minimal $60,000 exemption upon death.
US Estate Tax Due = max(0, Fair Market Value of US-Situs Equities - $60,000 Exemption) × Progressive Tax Rate (Up to 40%)
Cole Barrett's Reality Check
The Unvarnished Bottom Line"This is the biggest hidden risk in international investing. If you live in Latin America, Asia, or the Middle East and buy shares of Apple, Microsoft, or SPY through a US broker, the IRS classifies those shares as US-situs property. If you pass away, any balance over $60,000 is hit with a 40% US estate tax. Wealthy foreign investors bypass this completely by holding Irish-domiciled UCITS ETFs instead."

Real-World Example: Scenario Breakdown
Examining the real numbers for: A foreign non-resident investor holding an individual $1,000,000 equity portfolio upon sudden death
| Execution Metric | Offshore UCITS ETF Investor | Direct US-Listed Shareholder |
|---|---|---|
| Fee / Rate | 0.07% ETF Expense Ratio | $0 advertised commission |
| Spread / Buffer | Invested in Irish-domiciled S&P 500 UCITS ETFs (like CSPX/VUAA) held through an international brokerage | Bought direct US-listed equities (AAPL, NVDA, SPY) on a US-based retail trading account |
| Execution / Status | Assets were legally domiciled in Ireland; classified as non-US situs property for US estate tax purposes | Assets classified as US-situs property; IRS applied Section 2101 estate tax schedules above the $60k exemption |
| Total Cost / Result | Completely shielded wealth from US estate tax confiscation | Surrendered over one-third of total account wealth to US federal estate taxes |
How Brokers Weaponize This Term
If you are not a US citizen or green card holder and do not live in the United States, never hold more than $60,000 in direct US-incorporated stocks or US-domiciled ETFs. Hold your US equity exposure via Irish-domiciled (UCITS) ETFs to eliminate US estate tax liability.

What assets qualify as 'US-Situs' for foreign investors?
Shares of stock in corporations incorporated in the US, US real estate, and physical tangible property located in the US. US Treasury bonds and bank cash deposits are generally exempt.
