Cross-border tax
Rules that follow you across borders
Where you hold an investment can matter as much as what you hold. This page sets out the main cross-border tax questions for people resident in Singapore, without giving personal tax advice.
Last updated: 2026-09-25Holding US Equities: Direct Shares vs Irish UCITS ETFs
Holding an Irish UCITS ETF effectively retains an additional 15% of gross dividends compared to holding direct US equities for Singapore tax residents.
| Comparison Factor | Direct US-Domiciled Shares (e.g. VOO) | Irish-Domiciled UCITS ETFs (e.g. CSPX, VUAA) |
|---|---|---|
| Dividend Withholding Tax | 30% deducted at source (No SG-US Treaty) | 15% at fund level (US-Ireland Treaty) |
| US Federal Estate Tax Exposure | Up to 40% on US assets above $60,000 threshold | Exempt (Fund is domiciled in Ireland, non-US situs) |
| Singapore Capital Gains Tax | 0% (Singapore has no capital gains tax) | 0% (Singapore has no capital gains tax) |
| Trading Currency | USD (NYSE / NASDAQ) | USD / GBP (London Stock Exchange) |
Why domicile matters as much as the asset
Two funds can track the same index and still be treated differently, because tax follows the fund's domicile rather than what it holds. An Irish-domiciled fund and a US-domiciled fund holding the same shares can face different withholding on dividends paid to the fund.
For an individual, the relevant questions are usually: where is the asset held, what is the holder's tax residence, and what does the applicable treaty say.
US dividend withholding
Rates and treaty positions depend on the holder's status and can change. We are not tax advisers.
The United States generally withholds tax on dividends paid to non-resident holders, commonly at 30% for a Singapore-resident individual with no treaty relief.
Withholding is deducted at source, so the amount arriving is already net. It is not a separate filing you opt into.
US estate tax exposure for non-resident holders
Whether a particular asset is US-situated, and what threshold applies, depends on the asset and the holder's status. This is a general explanation only. Obtain advice for your own position.
The United States imposes estate tax on US-situated assets held by non-resident non-citizens. For many non-resident holders the threshold above which the tax applies is far lower than the threshold that applies to US citizens and residents.
US-situated assets can include shares in US-incorporated companies, including some funds. Where a fund is domiciled outside the United States, its shares are generally not US-situated for this purpose — which is one reason domicile matters.
India–Singapore cross-border treatment
We have not stated specific rates or thresholds for the India–Singapore treaty or the Indian remittance rules on this page, because they change and we have not verified the current figures against the primary sources. Check the Indian Income Tax Department and the treaty text directly.
India and Singapore have a double taxation avoidance agreement. Capital gains treatment under it depends on the type of asset, the holding period and the holder's residence status.
India also operates remittance rules that apply to residents remitting funds abroad, and reporting requirements for foreign accounts. These change, and the thresholds are set by the Indian authorities.
