W-8BEN explained for UK creators

What the W-8BEN form is

The W-8BEN is a US tax form issued by the IRS, the United States Internal Revenue Service. The full name is “Certificate of Foreign Status of Beneficial Owner for United States Tax Withholding and Reporting (Individuals).” In practical terms, it is the form an individual outside the US fills in to tell US-incorporated payers (Google, Twitch, Patreon, Stripe) two things: that the recipient is not a US person for tax purposes, and that the recipient is a tax resident of a country with which the US has a double taxation treaty.

Both of those statements are true for a UK creator, and stating them on the W-8BEN is what unlocks the treaty rate of withholding tax that the US otherwise applies at 30% to any payment leaving the country.

Why US platforms withhold tax in the first place

The US tax code requires US-incorporated payers to withhold tax on payments made to non-US persons unless those persons can prove eligibility for a treaty rate. The default withholding rate on US-source income is 30%. AdSense, Twitch, Patreon and Substack are all US-incorporated, so any creator income paid by them is US-source income from the IRS's point of view, regardless of where the creator lives.

Without a W-8BEN on file, the platform has no choice. It withholds the default 30% and remits it to the IRS. The creator receives 70% of what they earned. That 30% is real money, gone to the US treasury, and reclaiming it after the fact is possible but slow and paperwork-heavy.

The UK-US double taxation treaty and the 0% rate

The United States and the United Kingdom have a double taxation treaty (technically the “Convention between the Government of the United States of America and the Government of the United Kingdom of Great Britain and Northern Ireland for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion with respect to Taxes on Income and on Capital Gains,” signed in 2001). The point of a treaty like this is to prevent the same income being taxed twice by the two countries.

Under Article 12 of that treaty, royalties paid by a US payer to a UK resident are taxable in the UK only, at a treaty rate of 0% in the US. AdSense revenue is treated as royalties under the treaty. Twitch, Patreon and Substack income paid to a UK creator typically falls into the same category or into Article 7 (business profits), which is also taxable in the UK only.

Either way the result is the same. With a W-8BEN on file, the US withholds nothing. The creator receives the full payment, and the income is then declared on a UK Self Assessment return as self-employment income, taxed under UK rules.

How to file the W-8BEN on each platform

You do not post a paper W-8BEN to the IRS yourself. Each platform has its own version of the tax interview inside the creator dashboard, and submitting the answers there generates and stores the W-8BEN on the platform's file. From the platform's point of view, it now has documentation that justifies withholding at the treaty rate.

YouTube AdSense

Sign in to AdSense, go to Payments, then Manage settings, then United States tax info. Click “Manage tax info” and start the tax form. Select Individual, then Non-US person. Tick the W-8BEN box. Fill in your full legal name (the name HMRC has on file for you, not your channel name), country of citizenship (United Kingdom), permanent address (your registered UK address), and tax identification number. The TIN field accepts either your UK National Insurance number or your UTR. Check the Tax treaty section, claim the treaty benefits, and the system populates Article 12 with the 0% rate for royalties.

For a UK creator paid in USD through AdSense, see also our YouTuber accountant page for the wider treatment (foreign tax credit, monthly average rates, sponsorship and MCN handling).

Twitch

Sign in to your Twitch creator dashboard, go to Settings, then Channel, then Affiliate / Partner Onboarding (or the Tax forms section for existing Affiliates and Partners). Start the tax interview. Select Individual, Non-US person, and W-8BEN. The flow asks for the same details as AdSense (legal name, UK address, TIN, treaty claim). When you reach the treaty claim, select United Kingdom and confirm 0% withholding under Article 12.

Twitch revenue is more layered than AdSense: subscriptions, Bits, donations and ad revenue all interact with the W-8BEN differently in terms of how they post to the bank. Our Twitch streamer accountant page covers the reconciliation work end-to-end.

Patreon

Sign in to your Patreon creator dashboard, go to Settings, then Tax forms. Patreon runs its tax interview through Stripe (since payments are processed by Stripe). Start the W-8BEN flow inside Stripe Tax, select Individual, Non-US person, the W-8BEN form, and complete the treaty claim with United Kingdom selected.

Patreon income has its own quirks (the platform takes 8% or 12% depending on the plan, Stripe takes the processor fee on top, USD payouts need converting at HMRC monthly average rates). Full treatment on our Patreon accountant page.

Substack

Substack pays creators through Stripe, the same way Patreon does, so the W-8BEN is filed through the Stripe Tax interview attached to your Substack publication. Sign in to your Substack dashboard, go to Settings, then Payments, then Tax forms. Stripe Tax walks you through the W-8BEN with the same fields (legal name, UK address, TIN, treaty claim, Article 12 at 0%).

See our Substack accountant page for the subscription income, fee treatment and US-source income side of things.

What happens if you do not file it

Without a W-8BEN on the platform's file, the platform withholds the default 30% on US-source income and remits it to the IRS. For a UK YouTuber earning £45,000 a year in AdSense with 40% of audience in the US, that is roughly £5,400 a year withheld that should not be. Multiply across two or three platforms over multiple years and the back-of-envelope number gets uncomfortable.

HMRC does not refund US withholding. The US treasury does, but only on application and only for the relevant tax year through a foreign tax credit claim on the US return route. UK creators with significant US-source income usually find it cheaper and faster to file the W-8BEN immediately to stop future withholding, and to claim a foreign tax credit on Self Assessment for the residual withholding already taken.

Reclaiming past US withholding

There are two routes for getting back tax that was already withheld before the W-8BEN was filed. The first is the foreign tax credit on UK Self Assessment, which allows a UK creator to offset US tax already paid against their UK tax bill for the same income, up to the UK rate that would otherwise apply.

The second is a US Form 1040-NR refund claim, which the IRS processes for non-resident individuals seeking a refund of overwithheld tax. This is the slower and more paperwork-heavy route and is usually only worth pursuing for materially large amounts. Most UK creators we work with use the foreign tax credit route on their UK return.
