US vs Irish-Domiciled ETFs for Malaysians (2026)

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. Malaysia has no comprehensive tax treaty with the US 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 receives US dividends with only 15% withheld. 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 then charges nothing on distributions paid out to non-resident investors like Malaysians.

The net effect: roughly 15% withholding through Ireland versus 30% direct — you keep an extra 15 percentage points of every dividend.

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 gets an exemption of only US$60,000. US-listed stocks and ETFs — including VOO, VTI and QQQ — are US-situs assets. Above that US$60,000, the estate is exposed to US estate tax that starts at 18% and rises to 40%.

Only around 15 countries have an estate-tax treaty with the US that softens this. 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.

Accumulating vs distributing#

Irish UCITS ETFs usually come in an accumulating share class (the "Acc" in names like VUAA, or 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.

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 and Tiger Malaysia do not currently offer LSE trading. In practice that means using Interactive Brokers, which gives LSE access at low cost.
• 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.

Worked example: how big is the drag?#

The S&P 500's dividend yield is modest — around 1.2%–1.3% in 2026 (check the current figure). 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 — for most Malaysians, that is Interactive Brokers. You open the account, fund it in USD, then buy CSPX, VUAA, 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 that lets Irish-domiciled funds receive US dividends with only 15% withheld, versus the 30% a Malaysian faces directly. The fund claims the rate at fund level, so the saving sits inside the fund price. Ireland charges nothing on distributions to non-residents.

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 — gets only a US$60,000 exemption, 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 15%-versus-30% withholding saving 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 and Tiger Malaysia do not offer LSE trading, so most Malaysians use Interactive Brokers, then fund the account in USD.
