UK Dividend Tax for a US Citizen: How Both Countries Tax the Same Payout

UK dividend tax applies to a US citizen who is UK resident at 10.75%, 35.75% or 39.35% for the 2026/27 tax year, on dividends above a £500 allowance. The same dividend is also taxed by the IRS, usually at 0%, 15% or 20% if it is a qualified dividend. A tax credit, not an exemption, is what stops the two charges stacking, and the credit does not cover everything.

Most guides to dividend tax are written for one country. A US citizen living in Britain has to run both sets of rules over the same payment, in two currencies and two tax years. This guide sets out the UK charge, the US charge, which country gets to tax first, and the specific points where an American investor in the UK ends up paying more than either country's headline rate suggests. It builds on our wider guide to investing as an American in the UK.

How much UK dividend tax does a US citizen pay?

A US citizen who is UK resident pays UK dividend tax on the same terms as any other UK resident. Citizenship does not change the UK rate. What matters is UK residence, which is decided by the Statutory Residence Test, and the tax band your total income falls into.

GOV.UK gives the following for the tax year 6 April 2026 to 5 April 2027:

UK tax band	Rate on dividends above the allowance (2026/27)
Basic rate	10.75%
Higher rate	35.75%
Additional rate	39.35%

Two amounts are taken off first. Dividends that fall within any unused Personal Allowance are not taxed, and everyone gets a dividend allowance of £500 for 2026/27. Dividends are treated as the top slice of your income, so a salary that already fills the basic rate band pushes every pound of dividends into the higher rate.

The UK charge applies to dividends from companies anywhere in the world, including US shares held in a US brokerage account. The exception is the foreign income and gains regime: a new arrival who qualifies can claim relief from UK tax on foreign dividends for up to four tax years. That relief has no effect on the US side.

Dividends on shares held in an ISA are not taxed in the UK at all. Keep that in mind for later, because the IRS takes a different view.

How does the IRS tax the same dividend?

The IRS taxes a US citizen on worldwide income wherever they live, so every dividend that goes on a UK return also goes on Form 1040. The US rate depends on whether the dividend is an ordinary dividend, taxed at normal income tax rates, or a qualified dividend, taxed at the lower long-term capital gains rates.

IRS Topic no. 409 gives those lower rates as 0%, 15% and 20%. For tax years beginning in 2025, the 0% rate applies to taxable income up to $48,350 for a single filer or $96,700 for a joint return, and the 20% rate starts above $533,400 for a single filer or $600,050 for a joint return. The thresholds are adjusted each year, so check the current IRS figures for the year you are filing.

When is a UK dividend a qualified dividend?

IRS Publication 550 sets three conditions. The dividend must be paid by a US corporation or a qualified foreign corporation, it must not be on the list of excluded dividend types, and you must meet the holding period.

• Qualified foreign corporation. A foreign company qualifies if it is eligible for the benefits of a comprehensive US income tax treaty that the Treasury has approved for this purpose. Publication 550 lists those treaties in Table 1-3, and the United Kingdom is on the list. A UK trading company listed in London will normally meet this test.
• Holding period. You must have held the shares for more than 60 days during the 121-day period that begins 60 days before the ex-dividend date.
• Not a PFIC. Publication 550 says a company is not a qualified foreign corporation if it is a passive foreign investment company in the year the dividend is paid or in the previous year.

The third condition is the one that catches people. UK unit trusts, OEICs, investment trusts and most non-US exchange-traded funds are generally passive foreign investment companies for US purposes. Their distributions are not qualified dividends, and they carry the separate reporting described in our guide to ISAs and the PFIC rules. A dividend from a single UK company and a distribution from a UK fund look the same on a broker statement and are taxed very differently by the IRS.

The 3.8% Net Investment Income Tax

On top of income tax, the IRS charges a 3.8% Net Investment Income Tax on dividends and other investment income where modified adjusted gross income exceeds $200,000 for a single filer, $250,000 for a joint return or $125,000 for married filing separately. It is reported on Form 8960. The IRS questions and answers say foreign tax credits cannot be used against this tax, so it is often a true extra cost for an American in the UK.

Which country taxes the dividend first?

The answer depends on where the paying company is based, and it decides which country gives the credit. The US/UK income tax treaty deals with dividends in Article 10 and with relief from double taxation in Article 24. The treaty text is published on GOV.UK.

Dividend from	Taxed first by	Who gives the credit
A UK company	The UK, as the country of residence and of source. The UK does not deduct tax at source from ordinary company dividends; the tax is collected through Self Assessment.	The US, as a foreign tax credit on Form 1116 for the UK tax paid on that dividend.
A US company	The US, up to the 15% rate that Article 10 allows the source country on a portfolio dividend.	The UK gives Foreign Tax Credit Relief up to 15%. The US then gives credit for the remaining UK tax under the special rule for US citizens in Article 24.
A company in a third country	That country, at whatever rate its own treaties allow.	Both the UK and the US give credit under their own rules, each subject to its own limit.

A US citizen cannot simply use the treaty to cut the US tax to 15%. The treaty's saving clause lets the US tax its citizens as if the treaty did not exist, with a short list of exceptions. Article 24 is one of those exceptions, which is why the credit mechanism still works for an American in the UK.

On the UK side, GOV.UK explains that you may not get back the full amount of foreign tax you paid, and that you get less where a smaller amount is set by the double taxation agreement. For a US dividend that means HMRC credits no more than 15%, even if your US rate on the dividend was higher. Our guide to Foreign Tax Credit Relief in the UK walks through the claim.

Illustrative example: Rachel is a US citizen, UK resident and a higher rate taxpayer. In 2026/27 she receives £10,000 of dividends from UK listed companies held outside an ISA. The first £500 is covered by the dividend allowance. The remaining £9,500 is taxed at 35.75%, giving UK dividend tax of £3,396.25, which is about 34% of the whole dividend. On her US return the dividends are qualified, so the US tax is 15% of the dollar value. The UK tax is higher than the US tax, so the foreign tax credit on Form 1116 covers the US income tax in full and she carries the unused credit forward. If her income is above the Net Investment Income Tax threshold, she still owes 3.8% of the dividend to the IRS, because that tax cannot be reduced by the credit.

Where UK dividend tax and US tax do not line up

The credit system works well when both countries tax the same income, in the same year, at rates where the first country's tax is at least as high as the second's. An American investor in the UK meets several cases where one of those conditions fails.

ISA dividends

The UK charges nothing on dividends inside a Stocks and Shares ISA. The US taxes them in full. With no UK tax on the income there is nothing to credit, so the US tax is a real cost. An ISA holding individual company shares is at least straightforward to report. An ISA holding UK funds adds the PFIC rules on top.

The £500 allowance and the Personal Allowance

Dividends covered by the UK dividend allowance or an unused Personal Allowance carry no UK tax. The IRS has no matching allowance for dividends. A retired American in the UK with modest income can find that their UK dividend tax is nil while a US liability remains, depending on where their US taxable income falls against the 0% qualified dividend threshold.

Basic rate taxpayers

At the UK basic rate, dividend tax is 10.75% for 2026/27. If your US rate on qualified dividends is 15%, the UK tax does not cover the US tax and the difference is payable to the IRS. The combined cost is the higher of the two rates, not the sum, but it is more than a UK neighbour pays on the same shares.

Two tax years, two currencies

The UK tax year runs from 6 April to 5 April and the US tax year is the calendar year. A dividend paid in February falls in one UK year and a different US year from one paid in May. The UK tax on a dividend is often paid after the US return for that calendar year is due, so the timing of the credit needs planning. We cover the mechanics in UK tax year vs US tax year. Each dividend must also be converted from pounds to dollars for the US return, using a consistent exchange rate method.

Fund distributions and reinvested dividends

Accumulation units in a UK fund do not pay cash, but HMRC still taxes the notional distribution as dividend or interest income. The IRS, treating the fund as a PFIC, applies its own regime to the same holding. The income, the timing and the character can all differ between the two returns. This is the main reason US citizens in the UK are usually steered towards directly held shares or US-domiciled funds that also have HMRC reporting fund status.

How to report dividends in both countries

The reporting sequence matters as much as the calculation, because each return needs a figure from the other.

1. Collect statements by payment date. List every dividend with its payment date, the paying company, the gross amount and any tax withheld. UK brokers do not issue a US Form 1099-DIV, so this list is your source record.
2. Split by UK tax year and by calendar year. The same list feeds a 6 April to 5 April total for HMRC and a January to December total for the IRS.
3. Report to HMRC. GOV.UK says dividend tax on dividend income up to £10,000 can be collected by asking HMRC to change your tax code or by calling the helpline, and that dividend income over £10,000 needs a Self Assessment return. Anyone claiming Foreign Tax Credit Relief on US dividends needs the return and its foreign pages in any case. See our guide to the SA106 foreign income pages.
4. Report to the IRS. Dividends go on Form 1040. IRS Topic no. 404 says Schedule B is required if you receive more than $1,500 of taxable ordinary dividends. Identify which dividends are qualified yourself, using the three Publication 550 tests.
5. Claim the credit on Form 1116. Dividends normally fall in the passive category. UK tax paid on UK dividends is claimed here, and the treaty re-sourcing rule for US-source dividends is claimed on a separate Form 1116.
6. Check Form 8960 and Form 8621. Form 8960 calculates the Net Investment Income Tax. Form 8621 is needed for each PFIC, which includes most UK funds.

What people get wrong about dividend tax as a US citizen in the UK

• Assuming the treaty caps their total tax at 15%. The 15% in Article 10 limits what the source country may charge. It does not limit what your country of residence, or your country of citizenship, charges on top.
• Leaving ISA dividends off the US return. Tax-free in the UK does not mean tax-free in the US.
• Treating every dividend on the statement as qualified. Fund distributions and dividends on shares held for a short period fail the Publication 550 tests.
• Claiming the full US tax as a UK credit. HMRC limits relief on a US dividend to the treaty rate, and never gives more than the UK tax due on that same income.
• Forgetting the Net Investment Income Tax. Higher earners owe 3.8% to the IRS even when UK dividend tax is well above the US income tax rate.

Getting UK dividend tax and the US return to agree

Dividend income is where a portfolio built for a UK investor costs a US citizen the most, and where a small change in what is held, and where, makes a lasting difference. The right structure depends on your UK tax band, your US filing status, whether you are within the four-year foreign income and gains window, and how much of the portfolio sits in funds.

US/UK Cross Border Tax is a team of US CPAs and UK tax advisers working as one team, with offices in London, Manchester, New York and San Francisco.
