The US Estate Tax Trap for Non-US Expats (and How Irish UCITS Avoid It)
A non-US person holding US-domiciled ETFs such as SPY, VTI, or QQQ faces up to 40% US estate tax on the full value of those holdings above USD 60,000 at death. US citizens receive a basic exclusion of USD 13,990,000 (2025). Non-resident aliens receive none of it. Irish-domiciled accumulating UCITS funds track identical indices with no US estate tax exposure for non-US persons. For a European expat in Malaysia, Singapore, Thailand, or the Gulf, the fix is structural and straightforward.
Why non-US expats holding US-domiciled ETFs face a structural estate tax problem
The US estate tax system treats US citizens and non-US persons very differently. A US citizen or domiciliary can hold up to USD 13,990,000 of worldwide assets (2025 figure) before any US estate tax liability arises. For a nonresident alien (NRA), defined in US tax law as a person who is neither a US citizen nor US-domiciled at the time of death, the threshold is USD 60,000 on US-situated assets only. That threshold has not been indexed for inflation since it was established. It remains at USD 60,000 regardless of the year of death.
The issue for a European expat in SE Asia is that the most common index-tracking ETFs are US-domiciled. SPY (SPDR S&P 500 ETF Trust) is a US trust. VTI (Vanguard Total Stock Market ETF) is a US-registered fund. QQQ (Invesco QQQ Trust) is a US trust. Shares in these funds are US-situated assets under Internal Revenue Code Section 2104(a), which defines a non-resident alien's US estate as including stock in a US corporation and other US-sited assets. An NRA who holds USD 200,000 of SPY at death has a US estate well above the USD 60,000 threshold, and the taxable portion is subject to US estate tax at rates up to 40%.
The NRA unified credit under Form 706-NA is USD 13,000. This shelters the estate from tax on approximately the first USD 60,000 of US-sited assets given the progressive rate structure. Above that, US estate tax applies. The progressive rate schedule starts at 18% on the first USD 10,000 of taxable amount and reaches the top rate of 40% on taxable amounts exceeding USD 1,000,000. For a non-US expat with a six-figure or seven-figure portfolio concentrated in US-domiciled ETFs, the estate tax exposure is material.
This is not a theoretical edge case. It is the default outcome for any non-US person who invested in globally popular ETFs marketed to retail investors worldwide, built a portfolio, and died without restructuring it.
Who this affects
Any non-US person who is not a US citizen and has not acquired US domicile. This includes British, French, German, Spanish, Dutch, Romanian, and any other European national living in Malaysia, Singapore, Thailand, Gulf states, or elsewhere outside the United States. No treaty between the UK, EU member states, and the US provides the kind of estate tax relief that eliminates this exposure for the typical expat portfolio.
Which assets are US-situated for a non-resident alien's estate?
Under IRC Section 2104, the following are included in a non-resident alien's US estate: shares of stock issued by a US corporation; real property located in the United States; debt obligations (bonds, notes) issued by US persons where the interest would not qualify for the portfolio interest exemption; interests in US partnerships or entities treated as corporations; and US-sited tangible personal property.
US-domiciled ETFs fall squarely within this definition. SPY is structured as a unit investment trust, a US entity. VTI and QQQ are structured as open-end management companies registered under the US Investment Company Act of 1940. All are US entities. Shares or units in these funds held by a non-US person at death are US-situated assets included in the NRA's US estate.
The exposure extends beyond ETFs. Any individual US equity (Apple, Microsoft, Amazon) held directly in a brokerage account is a share in a US corporation and is US-situated. A US-listed stock portfolio of USD 500,000 held by a European expat in KL or Singapore carries US estate tax exposure on the full amount above USD 60,000. This is true whether the account is held at a Malaysian, Singaporean, or European broker. Situs is determined by where the asset is located or incorporated, not where the account is held.
By contrast, several categories of US-connected assets are specifically excluded from the NRA estate by statute. These include: certain US bank deposits held in the ordinary course of banking; proceeds of US life insurance on the life of the non-resident alien (under IRC Section 2105(a)); and original-issue discount (OID) obligations meeting the conditions of IRC Section 2105(b). These exclusions are narrow and do not cover the typical investment portfolio exposure.
| Asset type | US-situated for NRA estate? | IRC reference |
|---|---|---|
| Shares in US corporations (incl. US-domiciled ETFs: SPY, VTI, QQQ) | Yes | IRC s.2104(a) |
| US real property | Yes | IRC s.2104(a) |
| US-issued debt (bonds, notes) | Mostly yes; exceptions apply | IRC s.2104(b); s.2105(b) |
| Shares in Irish-domiciled UCITS (IWDA, CSPX, VWCE, EQQQ) | No (foreign corporation) | IRC s.2104(a) a contrario |
| US bank deposits (ordinary banking) | No (statutory exclusion) | IRC s.2105(b)(1) |
| US life insurance proceeds on NRA's life | No (statutory exclusion) | IRC s.2105(a) |

What the US estate tax actually costs a European expat in SE Asia
Consider a German national living in Kuala Lumpur. He is 48, not a US citizen, has never established US domicile, and holds a GIA portfolio equivalent to approximately USD 400,000. The portfolio was built over 10 years using widely recommended index funds: USD 200,000 in VTI, USD 100,000 in QQQ, and USD 100,000 in a non-US bond fund. He dies unexpectedly.
His US estate consists of the USD 300,000 held in VTI and QQQ. The USD 60,000 filing threshold is exceeded. The executor must file Form 706-NA with the IRS. The US estate tax calculation proceeds as follows. The gross US estate is USD 300,000. After deductions and the USD 13,000 unified credit offset, the taxable US estate is approximately USD 240,000. Applying the unified rate schedule: 18% on the first USD 10,000 = USD 1,800; graduating to 26% on amounts from USD 60,001 to USD 80,000; up to 32% on the USD 240,000 taxable amount. The approximate US estate tax liability on USD 300,000 of US-domiciled ETFs is roughly USD 64,000 to USD 70,000, depending on the exact progressive calculation and applicable deductions.
Now compare the same German national with a structurally equivalent portfolio: USD 200,000 in CSPX (iShares Core S&P 500 UCITS ETF, Irish-domiciled), USD 100,000 in EQQQ (Invesco EQQQ Nasdaq-100 UCITS ETF, Irish-domiciled), and USD 100,000 in a non-US bond fund. He holds shares in two Irish companies. Under IRC Section 2104(a), shares in foreign corporations are not US-situated assets. His US estate for Form 706-NA purposes is nil. No filing obligation. No US estate tax. His family receives the full USD 300,000 equivalent in Irish UCITS without a USD 60,000+ deduction for a tax the fund structure was always able to avoid.
The performance of CSPX versus VTI over the long term is negligible. The tracked index is essentially the same (S&P 500 large-cap US equities). The structural outcome at death is entirely different.
| Scenario | US estate value | Approx. US estate tax |
|---|---|---|
| USD 300,000 in VTI + QQQ (US-domiciled) | USD 300,000 | ~USD 65,000 |
| USD 300,000 in CSPX + EQQQ (Irish UCITS) | $0 | $0 |
| USD 1,000,000 in VTI (US-domiciled) | USD 1,000,000 | ~USD 345,800 |
| USD 1,000,000 in IWDA (Irish UCITS) | $0 | $0 |

Why Irish-domiciled accumulating UCITS eliminate US estate tax exposure
The mechanism is straightforward. Under IRC Section 2104(a), a non-US person's US estate includes "shares of stock issued by a domestic corporation." A domestic corporation is a US entity. An Irish UCITS fund is incorporated or constituted under Irish law and regulated by the Central Bank of Ireland under the UCITS Directive. It is a foreign entity for US estate tax purposes. Shares in a foreign corporation are not US-situated assets for an NRA's estate. The estate tax analysis therefore ends before it begins: there are no US-situated assets in the estate.
The fact that the Irish UCITS fund holds US equities internally does not change the analysis. The non-US person owns shares in an Irish fund. The Irish fund owns the US equities. US estate tax applies to what the NRA directly holds, not to what the fund holds on behalf of its shareholders. The fund structure interposes a foreign legal entity between the investor and the underlying US equities, and that foreign entity is the relevant holding for US estate tax purposes.
The practical equivalents are well-established. CSPX (iShares Core S&P 500 UCITS ETF, USD, LSE: CSPX) tracks the S&P 500 with a total expense ratio of 0.07%, matching SPY's index exposure. IWDA (iShares Core MSCI World UCITS ETF, USD, LSE: IWDA) provides exposure to over 1,500 developed-market companies across 23 countries, with approximately 70% in US equities. VWCE (Vanguard FTSE All-World UCITS ETF, USD, LSE: VWCE) covers approximately 3,700 companies across both developed and emerging markets. EQQQ (Invesco EQQQ Nasdaq-100 UCITS ETF, USD, LSE: EQQQ) tracks the Nasdaq-100, the equivalent of QQQ.
All four are accumulating funds: dividends received by the fund from underlying holdings are reinvested internally rather than distributed to shareholders. For a non-pension account, this means no annual income tax event on reinvested growth in jurisdictions that tax dividend income (the UK, for example). For SE Asia residents in Malaysia or Singapore where foreign-source income is not taxed on receipt, the accumulating structure provides clean compounding without distribution mechanics to manage.
SPY (US) vs CSPX (Irish)
SPY: US trust, US-situated asset, USD 60,000 NRA threshold applies. CSPX: Irish fund (iShares), identical S&P 500 index, 0.07% TER, no US-situated asset for NRA estate. LSE: CSPX in USD.
VTI (US) vs IWDA (Irish)
VTI: US-domiciled, covers US total market. IWDA: Irish fund (iShares), MSCI World (23 developed markets, ~70% US), accumulating, 0.20% TER. No NRA estate tax exposure. LSE: IWDA in USD.
QQQ (US) vs EQQQ (Irish)
QQQ: US trust, US-situated. EQQQ: Irish fund (Invesco), identical Nasdaq-100 index, accumulating. No NRA estate tax exposure. LSE: EQQQ in USD.
VWCE for global exposure

UCITS vs US ETFs for Expats: Full Structural ComparisonDoes holding US-domiciled ETFs inside a SIPP or offshore bond remove the US estate tax risk?
Inside a UK SIPP, the pension trustee is the legal owner of the assets, not the member. The SIPP trust is a UK entity. Under US estate tax analysis, there is a reasonable argument that the SIPP member does not directly hold the underlying US equities in the same way that a brokerage account holder does. The IRS has not published comprehensive guidance specifically addressing the US estate tax treatment of UK SIPP holdings for NRAs, and the position involves uncertainty.
In practice, SIPP providers that operate for international clients typically hold Irish UCITS as the default investment option precisely because the analysis is clean. An Irish UCITS fund held inside a SIPP presents no US-situated assets at any level of the analysis: the trust holds an Irish fund which holds US equities. Using Irish UCITS inside a SIPP does not just reduce the estate tax risk -- it removes it entirely and avoids the need to rely on an untested structural argument about pension trust characterisation under US law.
For assets held outside a SIPP -- in a general investment account, an offshore bond, or a platform account -- the position is straightforward. A US-domiciled ETF held in a GIA by a non-US person is a US-situated asset regardless of where the GIA is held. An Irish UCITS held in a GIA is not. The simplest and most permanent solution is to hold Irish UCITS equivalents across all account types, removing the US estate tax question entirely rather than relying on wrapper-level arguments that vary by structure and provider.
The offshore bond question is similar. An offshore bond is a life assurance policy issued by an insurance company, typically Irish or Isle of Man domiciled. The bond wrapper is the direct holding; the underlying fund units are held by the insurance company. If the underlying funds are US-domiciled ETFs, the analysis depends on whether the insurance company is itself US-situated. Most offshore bonds are structured to ensure the insurance company is a foreign entity, but confirming the underlying fund selection remains the cleaner approach.

International SIPP for SE Asia Expats Cross-Border Estate Planning for European ExpatsWhy this matters specifically for European expats in Malaysia, Singapore, and Thailand
A European expat in SE Asia is, by definition, a nonresident alien for US estate tax purposes provided they have not acquired US citizenship or US domicile. US domicile is a question of intent: a person is US-domiciled for estate tax purposes if they live in the US with the intention of remaining there indefinitely. An expat in Kuala Lumpur, Singapore, or Bangkok with no intention of settling in the US has not acquired US domicile and is subject to the NRA estate tax regime with the USD 60,000 threshold.
The SE Asia context adds several layers. Malaysian and Singaporean residents who have accumulated investment portfolios over years of regional work often hold US-domiciled ETFs because these were the most prominently marketed and easily accessible global index funds when they began investing. The portfolio composition was driven by availability and brand recognition, not by estate tax analysis. The result is that a large proportion of SE Asia-based European expat portfolios carry US estate tax exposure that the investor may not be aware of and that is simple to eliminate by switching to Irish UCITS equivalents.
Malaysia and Singapore do not impose inheritance taxes or estate duties on assets held by their residents. This means there is no local tax offset against the US estate tax liability if a non-US expat dies holding US-domiciled ETFs. The US estate tax is an additional cost, not a credit against a local liability. For UK nationals, the UK does not impose inheritance tax on the death of a non-UK domiciliary on assets outside the UK (subject to the long-term resident rules from April 2025), meaning the US estate tax on a Malaysian- or Singaporean-held portfolio is also not offset against a UK IHT liability.
The practical implication: for a European expat in SE Asia, Irish UCITS are the correct default across all accounts. The performance comparison with US-domiciled equivalents is negligible over any meaningful horizon. The estate planning comparison is not.
No inheritance tax + US estate tax exposure
Malaysia abolished estate duty in 1991. No inheritance tax, no gift tax. A European expat in KL holding USD 300,000 of US-domiciled ETFs pays nothing to Malaysia on death but faces US estate tax on the position above USD 60,000. The fix is straightforward: hold CSPX or IWDA instead of SPY or VTI.
No estate duty + US estate tax exposure
Singapore abolished estate duty in 2008. No inheritance tax. A European expat in Singapore holding a portfolio of US-domiciled ETFs faces the same USD 60,000 NRA threshold and up to 40% US estate tax as any other non-US person. Irish UCITS held through a Singapore brokerage carry no US estate tax exposure.
Limited inheritance tax + US estate tax exposure
Thailand has a limited inheritance tax at 10% (5% for parents and descendants) on assets above THB 100 million held in Thailand. Financial assets held offshore are generally outside Thai inheritance tax scope. US estate tax on US-domiciled ETFs held offshore operates independently. Using Irish UCITS removes the US estate tax exposure without affecting the Thai position.

The figures below are the primary numbers governing US estate tax exposure for a European expat holding US-sited assets. All sourced from IRS publications and the Internal Revenue Code.
| Figure | Amount | What it governs |
|---|---|---|
| NRA estate tax filing threshold | USD 60,000 | Form 706-NA must be filed if US-sited assets exceed this at death. Not indexed for inflation. |
| NRA unified credit (Form 706-NA) | USD 13,000 | The applicable credit amount available to NRAs; shelters approximately USD 60,000 of US-sited assets |

All 2025 figures.
Key Takeaway
- A non-US person holding US-domiciled ETFs such as SPY, VTI, or QQQ faces US estate tax at up to 40% on the value above USD 60,000 at death. The USD 60,000 threshold has not changed since it was established and is not indexed for inflation.
- US citizens receive a basic exclusion of USD 13,990,000 (2025). Non-resident aliens receive a unified credit of USD 13,000, sheltering only approximately USD 60,000 of US-sited assets.
- Irish-domiciled accumulating UCITS funds (CSPX, IWDA, VWCE, EQQQ) track the same indices as their US-domiciled equivalents. They are shares in Irish companies and are not US-situated assets for NRA estate tax purposes under IRC Section 2104(a).
- Situs is determined by where the asset is incorporated, not where the brokerage account is held. A European expat holding SPY through a Singapore or Malaysian broker still holds a US-situated asset.
- Malaysia and Singapore have no inheritance taxes. There is no local offset against US estate tax. For SE Asia-based European expats, the US estate tax on US-domiciled ETFs is an uncompensated additional cost that Irish UCITS eliminate.
- Inside a SIPP, using Irish UCITS removes any residual US estate tax uncertainty entirely. Outside a pension wrapper, in a GIA or offshore bond, Irish UCITS is the correct default for the same reason.
