Treaty Relief
Treaty, Form 8833, Form W-8BEN, Form W-8BEN-E
Claims under the US/UK income tax treaty, with Form 8833 disclosure, residence tie-breaker analysis and reduced withholding on US income.
What does Treaty Relief involve?
The US/UK income tax treaty decides which country may tax a given item of income, and at what rate. It is less generous to US citizens than most people expect, because of the saving clause. We identify which articles help on your facts and make the claims properly on both returns.
Forms and filings involved
- Treaty
How the US-UK income tax treaty allocates taxing rights, and where its saving clause limits what US citizens can claim.
- Form 8833
The disclosure required when a US return relies on the US-UK treaty to override or modify the ordinary US tax rules.
- Form W-8BEN
The certificate a non-US individual gives a US payer to confirm foreign status and claim treaty-reduced withholding on US income.
- Form W-8BEN-E
The certificate a non-US entity gives a US payer to confirm its foreign status, FATCA classification and any treaty claim.
- SA109
The Self Assessment pages for residence status, split-year treatment, treaty residence claims and foreign income and gains claims.
What the treaty does and does not do
The 2001 treaty allocates taxing rights by type of income: employment, dividends, interest, royalties, pensions, property and gains each have an article.
For US citizens its reach is limited by the saving clause in Article 1(4), which lets the US tax its citizens as if the treaty did not exist. Article 1(5) then lists exceptions. Those exceptions are where most useful claims for Americans in the UK are found, including parts of the pension articles and the article on relief from double taxation.
A position that relies on the treaty to override the Internal Revenue Code generally has to be disclosed on Form 8833, attached to the return. Some common claims are exempt from disclosure under the regulations and others are not, so each position is checked. On the UK side, treaty claims by individuals are made on the SA109 pages of the Self Assessment return. A claim made in one country should be consistent with the return filed in the other, because the two authorities exchange information.
For UK residents who are not US persons, the treaty mainly works through withholding. Without documentation, US-source dividends suffer 30% withholding. A valid Form W-8BEN claiming treaty benefits generally reduces that to 15% on portfolio dividends, and the form generally lasts until the end of the third calendar year after signing. For people resident in both countries under domestic law, Article 4 provides a tie-breaker. A long-term green card holder who uses it to claim non-residence should consider the expatriation rules first.

Questions we are asked
What is the saving clause and why does it matter to me?
It is Article 1(4) of the treaty. It lets the US tax its citizens and residents as if the treaty had never been signed, which removes most treaty benefits from a US citizen living in the UK. Article 1(5) lists the provisions that survive, including relief from double taxation, some pension rules and the Social Security rule. If you are a US citizen, a treaty article helps you only if it appears on that list.
I live in the UK and receive US Social Security. Which country taxes it?
Under Article 17(3), social security payments are generally taxable only in the country where the recipient is resident, and that paragraph is one of the listed exceptions to the saving clause. A UK-resident US citizen therefore generally reports US Social Security to HMRC and claims the treaty exemption on the US return. The position depends on being treaty resident in the UK, so the residence analysis comes first.
Do I have to tell the IRS when I rely on the treaty?
Often, yes. A return position that a treaty overrides or modifies US domestic law is generally disclosed on Form 8833, and there is a penalty for failing to disclose. The regulations waive disclosure for some routine claims, such as reduced withholding on dividends, while other common claims are reportable. A residence tie-breaker claim is always disclosed. Whether your position needs the form depends on which article you rely on.
