How US Dividends Are Taxed for Singapore Investors
By Joel · Updated 26 September 2026
The short answer
- →The US withholds 30% of dividends paid to Singapore residents, because there is no US–Singapore income tax treaty to lower the rate.
- →Singapore generally does not tax overseas income received by individuals, so for most investors the 30% is the only tax.
- →Return-of-capital distributions are not dividends and are generally not subject to the 30% withholding.
- →US-listed holdings above US$60,000 can trigger US estate tax for non-residents, which is a separate risk to plan for.
Why 30%?
US-source dividends paid to a non-resident alien are subject to 30% withholding at source unless a tax treaty sets a lower rate. The US has treaties with many countries, but not with Singapore, so Singapore residents pay the full 30%. Your broker deducts it automatically before the cash reaches your account.
To get this treatment rather than being mistaken for a US person, you file Form W-8BEN with your broker. Most brokers such as IBKR and Longbridge ask for it when you open the account.
| Gross dividend | $1,000 |
| US withholding (30%) | −$300 |
| Singapore tax | $0 |
| What you keep | $700 |
Singapore's side
IRAS states that overseas income received in Singapore by individuals is generally not taxable, including when it is deposited into a Singapore bank account. The exceptions are things like income received through a Singapore partnership, so ordinary personal investment dividends fall outside them.
The exceptions income investors should know
- Return of capital (ROC): many covered-call and option-income ETFs label part or all of their distributions as ROC. ROC is treated as a return of your own money, not a dividend, so it is generally not subject to the 30% withholding. Some brokers withhold on the full amount first and refund the ROC portion after the fund publishes its year-end tax breakdown.
- Irish-domiciled UCITS ETFs: funds domiciled in Ireland pay 15% withholding on their US dividends under the US–Ireland treaty, and Ireland generally does not withhold on the fund's distributions to Singapore investors. For plain dividend exposure this can beat the 30% on a US-listed fund.
- Some ETNs and specific structures are taxed differently. For example, I've found USOI's withholding gets refunded. Check each product's tax documents rather than assuming.
Don't forget US estate tax
Separate from dividends: if a non-resident dies holding US-situated assets (which includes US-listed stocks and ETFs) worth more than US$60,000, the estate may have to file a US estate tax return. It's one reason some Singapore investors hold part of their portfolio in Irish-domiciled funds.
This guide explains the general rules as I understand and apply them. It isn't tax advice, so check your own situation with a professional.
