You have decided to put money into the S&P 500 from Malaysia. Now the broker shows you two funds that track the exact same 500 companies: VOO and CSPX. They look interchangeable. They are not.
The difference is domicile — the country where each fund is legally based. VOO lives in the United States; CSPX lives in Ireland. That single legal fact quietly changes how much tax you pay on dividends every year, and whether your family faces a US tax bill if you die holding it. Most Malaysian investors default to the US-listed fund and never learn the alternative existed.

What "domicile" actually means
An ETF's domicile is the country where the fund is legally registered — its home jurisdiction — which is separate from where it puts your money. CSPX and VOO both hold the same basket of large US companies and track the same index. CSPX is domiciled in Ireland; VOO is domiciled in the United States.
That legal home is what a tax authority looks at. For a Malaysian investor — who has no tax treaty with the US — the fund's domicile decides two things: how much of your dividends the US keeps, and whether the holding sits inside the US estate-tax net.
Tax difference 1: dividend withholding — 30% vs 15%
When a US-listed fund like VOO pays a dividend to a Malaysian investor, the US Internal Revenue Service withholds 30% at source. The IRS's treaty table lists no income tax treaty with Malaysia to reduce that rate, so you receive 70% of the declared dividend. This is the same 30% figure covered in our how to buy ETFs guide — here we go one level deeper into how the Irish route changes it.
An Irish-domiciled fund works differently. Ireland does have a tax treaty with the US, so the fund itself can receive US dividends with only 15% withheld (IRS treaty table, Table 1; the fund must qualify for treaty benefits). That 15% is applied at the fund level — the ETF claims the treaty rate on the dividends it collects from its US holdings, and the saving is reflected inside the fund's price (its NAV), not on any statement you receive. Ireland is commonly said to charge nothing on distributions paid to non-resident investors like Malaysians; we did not verify that against Irish Revenue (HELD).
The net effect: typically 15% withholding through Ireland (IRS treaty table) versus 30% direct — you keep an extra 15 percentage points of every dividend.
The saving is invisible — that's normal
You will never see a "15% saved" line anywhere. The benefit is captured inside the Irish fund before any money reaches you, so it shows up as a slightly higher fund value over time rather than as cash or a tax refund. Do not go looking for it on your broker statement.
Tax difference 2: US estate tax — the one nobody mentions
This is the more serious issue, and it is almost never discussed. Under US rules, a person who is not a US citizen or resident and who dies owning US-situs assets faces a US$60,000 threshold. The IRS says an executor must file Form 706-NA if US-situated assets exceed US$60,000, and the maximum unified credit is US$13,000, which equals the tax on the first US$60,000 under the US rate schedule. US-listed stocks and ETFs — including VOO, VTI and QQQ — are US-situs assets. Above that, the estate is exposed to US estate tax at rates that start at 18% and rise to 40% (Form 706 instructions, Table A).
The IRS lists 15 countries with an estate-tax treaty with the US (Australia, Austria, Canada, Denmark, Finland, France, Germany, Greece, Ireland, Italy, Japan, the Netherlands, South Africa, Switzerland and the UK). Malaysia is not one of them. So a Malaysian who dies holding, say, US$100,000 of VOO could in principle leave their heirs facing US estate tax on the amount above US$60,000 — a tail risk most investors have no idea they are carrying.
Irish-domiciled ETFs are Irish-situs, not US-situs. They fall outside US estate tax entirely. For a long-term investor building a six-figure US-equity position, this is the single strongest argument for the Irish route.
This is a real, under-appreciated exposure
The estate-tax risk grows with your portfolio, not your income. A RM5,000 position is trivially above nothing; a RM400,000 US-domiciled ETF holding is well past the US$60,000 line. If you are accumulating for the long term, factor this in early — switching later means selling and rebuying. For the Malaysian side of estate planning, see our wills and estate planning guide; for the US exposure specifically, a cross-border tax adviser is worth it once your holdings are large.
Accumulating vs distributing
Irish UCITS ETFs usually come in an accumulating share class (an "Acc" or "Accumulating" share class, as with CSPX, which accumulates by default). Instead of paying dividends out as cash, an accumulating fund reinvests them inside the fund automatically. US ETFs like VOO distribute — they pay a cash dividend each quarter.
For an investor in the accumulation phase, accumulating is both simpler and tax-efficient: there is no cash distribution to reinvest manually, no drag from cash sitting idle, and the compounding happens inside the fund. Combined with the 15% withholding, an accumulating Irish fund is a clean, low-maintenance long-term holding.
The ticker map: what to buy instead of what
The Irish-domiciled equivalent of most popular US ETFs already exists on the London Stock Exchange.
| Exposure | US-domiciled | Irish-domiciled (accumulating) |
|---|---|---|
| S&P 500 | VOO / SPY | CSPX |
| Global (all-world) | VT | VWRA |
| Developed markets | — | IWDA |
| Nasdaq-100 | QQQ | CNDX / EQQQ |
Tickers as listed on the London Stock Exchange. Confirm the exact fund and share class on the manager's factsheet before buying — some funds offer both accumulating (Acc) and distributing (Dist) classes.
The trade-offs — why not everyone should switch
Irish-domiciled ETFs are not free of downsides:
- Slightly higher fees. CSPX charges around 0.07% a year against roughly 0.03% for VOO. A few basis points — usually outweighed by the withholding saving for a buy-and-hold investor, but real.
- You need LSE access. Irish UCITS ETFs trade on the London Stock Exchange, and moomoo's pricing page lists Malaysia, US, Hong Kong, Singapore and China A-share markets but not the LSE (we could not read Tiger Malaysia's pages, HELD). In practice that means a broker with LSE access; Interactive Brokers is the broker usually named for LSE access (not confirmed from its own pages, HELD).
- Smaller and less liquid than the US giants. VOO is one of the largest funds on earth; CSPX is large but smaller, with slightly wider bid-ask spreads. For a long-term holder this rarely matters.
- Currency line-up. LSE UCITS ETFs are priced in USD or GBP; you fund in USD.
Best for: Long-term, buy-and-hold Malaysian investors building a meaningful US-equity position (roughly RM100,000 and up) who use — or are willing to use — Interactive Brokers. For very small portfolios or investors who prize one-app simplicity, a US-domiciled ETF via moomoo or Tiger is a perfectly reasonable start.

Worked example: how big is the drag?
The S&P 500's dividend yield is modest. We use about 1.3% as an illustrative assumption, not a sourced current figure (HELD; check the current yield). The withholding difference applies only to that dividend, not your whole return:
- US-domiciled (VOO): 30% of a ~1.3% yield ≈ 0.4% of your holding lost to withholding each year.
- Irish-domiciled (CSPX): 15% of a ~1.3% yield ≈ 0.2% each year.
- Difference: roughly 0.2% a year — modest annually, but it compounds over decades, and it is essentially free to avoid.
The honest read: the annual dividend saving is small because US index yields are low. The real reasons to choose Irish-domiciled are (1) it costs almost nothing to capture that saving anyway, and (2) the estate-tax protection removes a genuine, poorly-understood tail risk. If you are income-focused (holding higher-yielding US assets), the withholding gap matters much more.
How to actually buy them
Irish-domiciled UCITS ETFs are bought on the London Stock Exchange through a broker that offers LSE access — Interactive Brokers is the broker usually named for this (not confirmed from its own pages, HELD). You open the account, fund it in USD, then buy CSPX, VWRA or their peers like any other stock. The one operational hurdle is getting ringgit into the account as USD, which we cover step by step in how to fund a US brokerage from Malaysia.
Common questions
What does it mean for an ETF to be "domiciled" in Ireland or the US?
Domicile is the fund's legal home country, not where it invests. CSPX and VOO hold the same US companies, but CSPX is legally based in Ireland and VOO in the US — and that legal home decides your tax treatment as a Malaysian.
Why do Irish-domiciled ETFs only pay 15% US dividend withholding?
Ireland has a tax treaty with the US, and the IRS's treaty table lists a 15% rate on dividends paid by US corporations to Irish residents (versus the 30% a Malaysian faces directly). The fund claims the rate at fund level, so the saving sits inside the fund price. Ireland is commonly said to charge nothing on distributions to non-residents; not verified (HELD).
What is US estate tax and does it really apply to Malaysians?
Yes. A non-US person dying with US-situs assets — including US-listed ETFs like VOO — faces a US$60,000 filing threshold (the maximum US$13,000 credit equals the tax on the first US$60,000), above which US estate tax runs 18%–40%. Malaysia has no estate-tax treaty with the US. Irish-domiciled ETFs are Irish-situs and fall outside this.
Are Irish-domiciled ETFs more expensive than US ones?
Slightly — CSPX is around 0.07% a year versus about 0.03% for VOO. For a buy-and-hold investor the typical 15%-versus-30% withholding saving (15% per the IRS treaty table) usually more than covers that gap, and the estate-tax protection is free.
How do I buy Irish-domiciled ETFs from Malaysia?
They trade on the London Stock Exchange. moomoo's pricing page lists no LSE market and we could not read Tiger Malaysia's pages (HELD); Interactive Brokers is the broker usually named for LSE access (not confirmed from its own pages, HELD). Then fund the account in USD.

Amendment, 17 October 2026. We re-read IRS pages and publications and the iShares and Vanguard fund pages and saved them in docs/verification-log/evidence-batch-a-oct17. Confirmed: US withholding of 30% on dividends to non-resident aliens absent a treaty (IRS); Malaysia is not on the IRS income-tax or estate-tax treaty lists, and Ireland is on both; IRS estate-tax treaty list has 15 countries; US$60,000 filing threshold and US$13,000 maximum unified credit on Form 706-NA; estate tax rate schedule 18% to 40%; CSPX is Irish-domiciled and accumulating with a 0.07% total expense ratio (iShares); VOO's expense ratio is 0.03% (Vanguard); the Vanguard UK S&P 500 UCITS ETF page we read is Irish-domiciled with a 0.07% OCF (it is the VUSA page, not VUAA; see the follow-up amendment below). Clarified: the US$60,000 is the filing threshold and credit-equivalent rather than a deduction, as the IRS words it. Held: the 15% Ireland-US dividend treaty rate (the IRS rate table could not be read as text), Ireland's treatment of distributions to non-residents, the S&P 500 yield used in the worked example, VWRA, IWDA and CNDX details, and whether Tiger offers LSE (moomoo's listed markets do not include it).
Amendment, 17 October 2026 (follow-up, evidence batch I). We re-fetched the IRS's tax treaty tables (Table 1 and Table 3), the US–Ireland treaty text, the IRS estate-tax pages and Form 706-NA, and the iShares and Vanguard fund pages, and saved them in docs/verification-log/evidence-batch-i-oct17. Sourced (was HELD): the IRS's Table 1 lists 15% as the treaty rate on dividends paid by US corporations to Irish residents (Ireland; Article 10(2)), with 5% for qualifying direct-dividend holdings, and has no row for Malaysia; the guide's "15% (not re-verified)" and "commonly stated" wording is now sourced to the IRS, with the caveat that the fund must qualify for treaty benefits. Corrected: "moomoo and Tiger Malaysia do not offer LSE trading" now says what we read (moomoo's pricing page lists no LSE market; Tiger Malaysia's pages could not be read) and that we could not confirm LSE access on Interactive Brokers' own pages (HELD). Confirmed (unchanged): 30% US withholding without a treaty, the US$60,000 filing threshold, US$13,000 maximum unified credit, 18% to 40% estate tax rates, 15 estate-tax treaty countries without Malaysia, CSPX Irish-domiciled, accumulating, 0.07% total expense ratio, VOO 0.03%. Removed (follow-up, 24 October 2026): every mention of VUAA. The Vanguard UK page we saved as vanguard-uk-vuaa.html is the S&P 500 UCITS ETF (USD) Distributing page (ticker VUSA; it contains no "VUAA" text), so it does not support any claim about VUAA, and we could not find the VUAA page. The VUAA ticker, its accumulating class and its 0.07% OCF are HELD. Still HELD: Ireland's treatment of distributions to non-residents (Irish Revenue's pages returned no usable text), the 1.3% S&P 500 yield, VWRA, IWDA and CNDX details, and LSE access at brokers.
Amendment, 17 October 2026 (review follow-up). Reworded as HELD: two Interactive Brokers LSE-access statements now say the broker is the one usually named and that LSE access is not confirmed from its own pages: the DirectAnswer ("such as Interactive Brokers (LSE access not confirmed from its own pages)") and the "You need LSE access" bullet (it said Interactive Brokers "gives LSE access at low cost"); the FAQ answers already said this. Reworded as HELD: the FAQ on the treaty said "Ireland then charges nothing on distributions to non-resident investors" as fact; it now says this is commonly said and not verified against Irish Revenue, as the body text already did. No figure changed.
