US dividend withholding tax calculator

Estimate one year of US dividend withholding on a holding, in US dollars. Hong Kong is the default: no income tax treaty, so the statutory rate is 30%. You can switch to other residences and compare a US-domiciled ETF with an Ireland-domiciled UCITS.

For the background, read why US dividends are withheld at 30%.

Estimate only, not tax, legal, or investment advice. Read the disclaimer. Treaty eligibility depends on your circumstances.

How this calculator works

The formula

Withholding is a percentage of the gross dividend. There is no allowance. The rate depends on residence and on whether Form W-8BEN is on file.

Market value = share count × price per share

Gross dividend = market value × dividend yield

Gross dividend = share count × annual dividend per share

US tax withheld = gross dividend × withholding rate

Net dividend = gross dividend − US tax withheld

Effective yield = net dividend ÷ market value

Annual drag (USD) = US tax withheld

Annual drag (HKD) = US tax withheld × HKD per USD

Assumptions

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.

Worked example

A Hong Kong resident with Form W-8BEN on file, a holding of US$10,000.00, and a dividend yield of 3% has a gross dividend of US$300.00. US tax withheld is US$90.00. The net dividend is US$210.00. The effective yield is 2.10%. Annual drag is US$90.00, or HK$702.00 at 7.80 HKD per USD.

The same holding for a United Kingdom resident with Form W-8BEN on file is withheld at 15%: US$45.00. The Ireland-domiciled UCITS column on that same gross dividend withholds US$45.00 at fund level.

Hong Kong does not tax this dividend for an individual

For an individual investor, a US dividend is not salaries tax and it is not property tax. The foreign-sourced income exemption regime does not cover a natural person. This calculator therefore stops at the US withholding. It does not add a second Hong Kong tax.

That is not a ruling on profits tax. If you carry on a business of dealing in securities, ask the Inland Revenue Department or a licensed adviser. Nothing here is tax advice.

Common questions

Why is 30% withheld from a Hong Kong investor’s US dividends?

The United States withholds 30% of the gross amount of US-source dividends paid to a non-US person, unless a tax treaty sets a lower rate. Hong Kong has no US income tax treaty, so a Hong Kong resident generally stays at 30%.

Does Form W-8BEN cut a Hong Kong investor’s rate to 15%?

No. Form W-8BEN certifies that you are not a US person and is how a treaty resident claims a lower rate. Hong Kong has no treaty, so the dividend rate stays at 30%. Without the form, a broker may withhold at 30% or apply backup withholding at 24%.

How does an Ireland-domiciled UCITS compare with a US-domiciled ETF?

A US-domiciled ETF pays you a US-source dividend, so a Hong Kong investor is withheld at 30%. An Ireland-domiciled fund receives the US dividends itself. IRS Table 1 shows a 15% general dividend rate for Ireland, if the fund qualifies. The comparison ignores fees, tracking difference, and US estate tax, and it is not a fund recommendation.

Does Hong Kong tax the dividend again?

Not for a typical individual investor. Salaries tax covers employment income and property tax covers rent. Dividends are neither, and a natural person is outside the foreign-sourced income exemption regime. A person carrying on a business of dealing in securities can be in a different position.
