Compare VWRA, CSPX, SPYL, and US-listed ETFs by dividend withholding tax, expense ratios, FX spreads, and broker fees for Singapore investors.
When you buy a US-domiciled ETF like VOO from Singapore, every dividend it pays you is withheld at 30% before it ever reaches your account because Singapore has no tax treaty with the United States. An Irish-domiciled UCITS fund like CSPX holds the same S&P 500 stocks, but thanks to the US-Ireland treaty it loses only 15% at fund level, and Ireland withholds nothing on what it passes to you. On a 1.3% dividend yield, that difference compounds into a meaningfully larger balance over decades.
For investors who want to “VWRA and chill”, “SPYL and chill”, or simply set and forget a monthly ETF plan, domicile and tax drag still matter. Two funds can hold similar stocks while leaving you with different after-tax results.
The calculator runs the same monthly investment plan down three paths: a US-domiciled fund (30% dividend withholding), an Irish-domiciled fund (15%), and a frictionless zero-fee baseline. Each month it invests your contribution net of FX spread and broker commission, grows the balance at your expected return split into price growth and dividends, reinvests dividends net of withholding tax, and deducts the fund’s TER plus any platform fee. The withholding gap is the headline number: how much more the Irish route leaves you with, after netting off any TER difference between the two funds.
Withholding tax is the biggest hidden cost for most Singapore index investors, but it is not the only one. A 0.3% FX spread on every SGD→USD conversion, a $2 commission on every monthly buy, and a platform fee of even 0.2% a year each take their own compounding bite. The cost-drag breakdown shows each component separately so you can see which lever, whether fund domicile, broker choice, or FX, is actually worth optimising.

Singapore has no tax treaty with the United States, so dividends paid by US-domiciled funds to Singapore residents are withheld at the full 30% rate. Irish-domiciled UCITS funds holding the same US stocks suffer only the 15% US-Ireland treaty rate at fund level, and Ireland does not withhold tax on distributions to Singapore investors.
Usually, but not automatically. Irish UCITS funds often have slightly higher expense ratios than their US-listed equivalents, so for very low dividend yields the TER difference can matter. This calculator nets the two effects so you can compare on your actual numbers.
No, but it is another reason many Singapore-based investors prefer Irish-domiciled funds. US-situs assets above US$60,000 can be exposed to US estate tax of up to 40% for non-resident aliens, while Irish-domiciled funds are outside its scope.
