Every figure on this page uses the assumptions below. Rates were checked on 3 October 2026.
- Statutory rate
- 30% of the gross US-source dividend when no treaty applies. IRS Publication 515, and NRA withholding under Internal Revenue Code sections 1441 to 1443. The NRA withholding page was last reviewed by the IRS on 14 March 2026.
- Treaty rate
- The general portfolio dividend rate in IRS Tax Treaty Table 1 (Rev. May 2023), column “Paid by U.S. Corporations — General”. This is not the direct-dividend rate, which is for a company that owns the required voting percentage, generally 10%. A personal holding does not use that column.
- Who is listed
- Hong Kong, Singapore, Taiwan, and Malaysia are not on the IRS A-to-Z list of income tax treaties (IRS page last reviewed 3 January 2026; re-checked 3 October 2026), so the rate is 30%. Other rows use the Table 1 general rate. Jurisdictions left off the list are omitted on purpose. Do not assume they are 15%. The Mainland China treaty does not cover a Hong Kong resident.
- Eligibility
- Table 1 does not decide whether you qualify. Footnotes, a limitation-on-benefits article, and the treaty text can deny the rate. The calculator applies the table’s general rate only after you say Form W-8BEN is on file.
- Form W-8BEN
- You give it to the broker, not to the IRS. It certifies that you are not a US person and, in Part II, claims a treaty rate. For Hong Kong it does not reduce the 30% dividend rate. A form generally stays valid from the day you sign it until the last day of the third calendar year after that, unless your circumstances change (Instructions for Form W-8BEN, revised October 2021).
- No W-8BEN
- The result uses 30%, even for a resident of a treaty partner, because the treaty rate is not claimed. The W-8BEN instructions say that if you do not provide the form, the broker may have to withhold at the 30% rate or at the backup withholding rate. Backup withholding is 24% (IRS backup withholding page, reviewed 28 June 2026). This calculator does not switch the result to 24%. Which rate a broker uses depends on how the account is documented.
- One year
- The gross dividend is one year of ordinary dividends on the holding you enter. It is not a forecast, and dividends are not reinvested here.
- Ireland-domiciled UCITS
- The fund receives the US dividends. The comparison uses Ireland’s 15% general treaty rate at fund level, if the fund qualifies. It is not a second US withholding on the distribution you receive. Fees, tracking difference, Irish tax, and US estate tax are not in the figure.
- US-domiciled ETF
- Treated as a US-source dividend paid to you, at your rate. For a Hong Kong investor that is 30%. A treaty rate below 15% — Japan is 10% in Table 1 — can make the US-domiciled column lower than the Irish column. That is only the US withholding layer, not a fund recommendation.
- Hong Kong dollar
- Drag in HKD is the USD tax multiplied by the rate you type. The default 7.80 sits inside the HKMA convertibility zone of 7.75 to 7.85 per US dollar. It is not a live market quote.
- Hong Kong tax
- Salaries tax is on employment income. Property tax is on rent. Dividends an individual receives are neither. The Inland Revenue Department’s foreign-sourced income exemption FAQ says a natural person is not an entity covered by that regime. Someone carrying on a business of dealing in securities can have a different profits-tax position. This page does not decide which one you are.
- Left out
- US capital-gains tax, qualified-dividend rates for US persons, state tax, fund expenses, and US estate tax on US-situs assets. Those are separate questions.
