W-8BEN: UK authors and US settlements (2026–27)
W-8BEN for UK authors: can US settlement withholding fall to 0%? Learn which lines to complete, treaty conditions and UK reporting for the 2026–27 tax year.
How should a UK-resident author complete Form W-8BEN for a US copyright settlement, and how is a payment received in the 2026–27 UK tax year taxed?
A valid W-8BEN can support a claim to a 0% US treaty withholding rate, while the author's share remains reportable in the UK. Eligibility, payment classification and timing depend on individual circumstances.
Figures below are illustrative. The UK tax year 2026–27 runs from 6 April 2026 to 5 April 2027; later instalments may fall in a different year.
A typical UK author receiving a US settlement
Consider an individual who is resident in the UK for treaty purposes, earns professional writing income, is the beneficial owner of the settlement income and has no US permanent establishment. The individual is neither a US citizen nor a green card holder.
The immediate issue is separate from the UK tax bill: what documentation does the US payer need before releasing the payment?
Form W-8BEN is not a tax return. It is given to the payer or settlement administrator, rather than sent to the IRS. It certifies foreign status and provides the basis for claiming treaty relief. Establishing foreign status alone does not establish entitlement to a reduced treaty rate.
Without a valid treaty claim, the US withholding rate considered in this case is 30%. Where the treaty conditions are satisfied, the analysis supports a 0% rate.
Lines 6a, 6b and 7: the practical answers
Line 6a: use the UK tax identification number
The form allows a treaty claim to be supported by either a US tax number on line 5 or a foreign tax identification number on line 6a.
For a UK individual, the National Insurance number is the first choice identified in HMRC's guidance. Its format is two letters, six digits and a final letter; enter it without spaces. The analysis also identifies the ten-digit Self Assessment UTR as an alternative accepted in practice. Enter one number only, not both.
If a previous US payer already uses one of those numbers, using the same number can help maintain consistency. The foreign tax number should correspond to the country of tax residence shown in the permanent-address section.
For the individual described here, who has no SSN or ITIN, line 5 can remain blank: a foreign tax number can support the treaty claim without an ITIN application solely for that purpose.
Line 6b: leave it unticked when a UK number exists
The box marked “FTIN not legally required” addresses situations where an individual is not legally required to obtain a foreign tax number, including countries that do not issue one.
It should remain unticked for the example author who has a UK tax number. Ticking it while entering a number can make the form inconsistent. Leaving the form without the tax number needed for treaty relief can prevent the payer from applying the reduced rate.
Line 7: add a matching reference
Line 7 is optional. A settlement claim reference can help the administrator match the form to the right payment. Where several claim references apply, they can be listed.
Do not enter a password or portal PIN. Omitting this optional reference does not itself invalidate the form.
Complete the rest of Part I consistently
The identifying information must describe the individual who beneficially owns the income:
Line 1: legal name, rather than a pen name.
Line 2: country of citizenship. Where a dual citizen is also resident in one of their countries of citizenship, the instructions direct them to use that country.
Line 3: permanent residential address in the country of tax residence; a PO box or “care of” address is not accepted.
Line 4: mailing address, if different.
Line 5: US tax number, if applicable; blank in the example above.
Line 8: date of birth in US month-day-year order where required. The analysis recommends completing it in this case even though the specific instruction concerns account holders at US financial institutions.
Treaty residence and citizenship are different concepts. A UK treaty claim rests on qualifying UK residence; citizenship alone does not establish that entitlement.
Part II: claim the UK–US treaty rate
Line 9: state treaty residence
Enter “United Kingdom” on line 9 only where the individual is a UK resident within the meaning of the treaty.
The UK–US convention was signed on 24 July 2001, entered into force on 31 March 2003, and has applied to withholding taxes since 1 May 2003.
Under Article 12(1), royalties arising in the US and beneficially owned by a qualifying UK resident are taxable only in the UK, subject to the treaty's conditions. The definition includes payments for the use of copyright in a literary work.
An individual resident in the UK is a qualified person under the treaty's limitation-on-benefits provisions.
Line 10: explain the article and rate
The analysis explains that line 10 is compulsory only in specified situations, including certain treaties with different rates for different royalty categories. Although the UK treaty has a single royalty rate, completing the line can make the claim clearer.
Where the payment is treated as literary copyright royalties and the conditions are satisfied, the example wording is:
Article and paragraph: 12(1).
Rate of withholding: 0%.
Type of income: royalties (copyright in a literary work).
Explanation: “The beneficial owner is an individual resident in the United Kingdom, is the beneficial owner of the income and has no permanent establishment in the United States.”
The payment's classification must still be established. The supplied analysis did not establish how the settlement administrator would characterise the payment.
If the payment instead falls outside the treaty's specific income articles, Article 22(1) on other income may produce the same UK-only taxation result. Both routes have an exception for relevant income attributable to a US permanent establishment. They should therefore not be presented as an unconditional exemption for every recipient.
What the withholding difference looks like
Suppose the author's own gross share is US$1,000, after any allocation to other rightsholders.
At 30% withholding, the US deduction would be US$300, leaving US$700 before UK tax.
At 0% treaty withholding, the US deduction would be US$0, leaving US$1,000 before UK tax.
A zero US withholding rate does not make the receipt tax-free in the UK. Nor does the amount received by another rightsholder automatically become the author's income.
Signing, submission and validity
Sign and date Part III, print the signer's name and complete the capacity certification as appropriate. An individual signing for themselves certifies their capacity to sign for the beneficial owner.
Provide the signed form through the administrator's designated official channel before payment where possible, and retain a copy. The analysis does not establish whether a newly submitted form will be processed in time for a particular distribution.
A W-8BEN generally remains valid until the end of the third calendar year following the year of signature. A form signed in November 2026 would therefore run to 31 December 2029, unless a change in circumstances affects its validity.
A new form must be provided within 30 days if a statement on it becomes incorrect, for example following a relevant change of residence.
UK reporting in 2026–27
For an author taxed on the profits of a writing profession, copyright receipts form part of professional income. Compensation or damages connected with that activity are normally receipts of the activity, including settlements where legal liability was not established.
On the facts of this example, the author's own share is added to writing income and converted into sterling. It is not treated as a tax-free windfall or a capital gain.
A receipt in November 2026 should in principle fall in 2026–27, subject to the accounting basis used. The accountant should determine the correct recognition year, particularly where payments arrive in stages.
Keep the following:
Gross amount in US dollars and the author's allocation.
Payment date and sterling amount credited.
Any US tax withheld.
Form 1042-S, which reports the relevant payment and withholding.
Creators of literary or artistic works may qualify to average profits over two consecutive tax years where the conditions are met. The relief is not available where profits are calculated on the cash basis. Whether averaging helps depends on the accounting basis, the years concerned and other writing income.
If US tax is withheld despite treaty relief
UK foreign tax credit relief is limited to the minimum foreign tax due under the treaty. Where relief was not claimed, the credit is limited to what would have been payable had the claim been made.
Consequently, where the treaty entitlement is 0%, a 30% US deduction cannot simply be assumed to produce an equivalent UK tax credit. The full gross income can remain subject to UK tax while the excess US withholding needs to be recovered separately.
First contact the administrator promptly with a complete or corrected form and ask whether the deduction can be corrected at payer level.
If that fails, the analysis identifies a US refund route through Form 1040-NR, requiring an ITIN for an individual without a US tax number. It refers to a three-year refund-claim period; the applicable filing and refund deadline should be established for the particular payment. The cost and administration of that route may be significant relative to a small refund.
Frequently asked questions
Is a National Insurance number enough without an ITIN?
For the treaty claim described here, the foreign tax number on line 6a can replace a US number that would otherwise be needed solely for treaty relief. That does not remove any separate US filing or identification obligation that may arise.
Should line 6b be ticked if line 6a is completed?
For the example UK author who already has a UK tax number, leave it unticked. It is intended for people who are not legally required to obtain a foreign tax number.
Does line 7 determine the withholding rate?
No. It is an optional matching reference; the tax number and valid Part II treaty claim are central to the relief discussed here.
Can the settlement be described as compensation instead of royalties?
Its classification must be established. The analysis considers Article 12 for royalties and Article 22 for qualifying other income, both subject to the relevant treaty conditions and permanent-establishment exception.
Is a settlement taxed only when the final instalment arrives?
Each receipt must be allocated to the correct tax year under the accounting basis used. Separate instalments may fall in different UK tax years.
Can excess US withholding be deducted from UK tax?
Do not assume so. Where the treaty permits no US tax, the analysis indicates that excess withholding must be addressed on the US side rather than credited automatically against UK tax.
