Quick answer
The Twitch tax interview produces a US Form W-8BEN confirming you are a non-US person resident in the UK. Complete both the royalty and service interviews with your National Insurance number and a UK treaty claim, or Twitch can withhold up to 30% from payouts. You still pay UK tax on all Twitch income.

Problems you face, answered
Twitch is a US company paying through Amazon's tax tools. Without a valid W-8 on file it must apply default US withholding of up to 30% to certain payments.
Amazon's guidance says a W-8 is valid from signing until the last day of the third following calendar year. A form signed in 2026 runs to 31 December 2029.

How Twitch Tax Interviews Works
What should I enter in the royalty interview? Answer as an individual, non-US person, with your legal name and UK home address. In the foreign tax identifying number field, UK individuals generally use their National Insurance number. Then claim UK treaty benefits. Article 12 of the UK–US tax treaty makes royalties taxable only in the country where the owner lives, which is why a correct claim usually stops US withholding on income Twitch classes as royalties.
What about the service interview? US tax generally applies to services performed in the US. If you stream from home in the UK, your services are performed outside the US, so there is normally nothing to withhold. If you stream from a US event, take advice before answering.
Does the tax interview change my UK tax? No. It only affects US withholding at source. Twitch income is trading income here: declare it in sterling on your Self Assessment return, deduct allowable costs, and pay Income Tax and National Insurance on the profit.
What if US tax was already taken? Fix the interview first so future payouts are correct. HMRC's foreign tax credit relief helpsheet HS263 limits relief to the lowest of the UK tax on that income, the foreign tax paid and the relief the treaty allows. Tax withheld beyond the treaty rate is not creditable in the UK, so it would need to be reclaimed from the US side.
From our experience: Streamers often spot withholding only when payouts look short. Check your annual Form 1042-S, which shows US-source payments and tax withheld.

Allowable expenses for streamers
How HMRC’s rules apply to streamers
If you are self-employed
Self-employed costs must be incurred wholly and exclusively for your trade. If you use the £1,000 trading allowance, you cannot also deduct actual expenses against that same income. Equipment treatment depends on cash basis or traditional accounting.
If you run a limited company
A limited company deducts costs incurred wholly and exclusively for its business. Equipment may need capital allowances rather than an immediate expense deduction. Personal use or company-paid private costs can create a taxable benefit or director’s loan entry; company ownership is not a blanket deduction.
For separable mixed-use costs, such as a phone bill, claim only the identifiable business proportion and keep evidence. This does not make ordinary clothing or every dual-purpose purchase deductible. A receipt alone does not prove a business purpose: retain the brief, invoice or usage record too.
Costs to review for your work
- The business share of a streaming PC, microphone and capture card
- Moderation, editing fees and stream software used for your channel
- Games bought solely for revenue-generating content, excluding personal play
Everyday clothing, ordinary grooming, personal meals, private gaming and fines are generally not deductible. Qualifying costumes or protective clothing and business-travel subsistence have different rules. Client entertaining is generally disallowed. Receiving a product from a brand does not automatically create an expense: record the income treatment separately and deduct only an allowable business cost.
