Buried in your AdSense settings is a tax form that decides whether the US government takes a slice of every dollar your American viewers generate. File it right and UK creators typically pay 0% US withholding on AdSense royalties. Ignore it and Google can withhold up to 30% of your US earnings — money you'll struggle to ever see again.
Why this exists
The US taxes income paid from US sources to foreign persons at 30% by default. But the UK–US tax treaty slashes that rate for UK residents — for the royalty-type income AdSense pays, usually to zero. The W-8BEN (submitted through AdSense's tax-info section) is simply you certifying UK residence and claiming the treaty rate.
The three-minute health check
- Open AdSense → Payments → Manage settings → United States tax info.
- Check a form is on file, approved, and claiming treaty benefits for the UK.
- Check the withholding rate shown against royalties — UK creators should see 0% for AdSense royalties under the treaty.
- Diarise the expiry: W-8BENs lapse (generally after three calendar years) and an expired form silently reverts you to punitive default withholding.
Streamers: same story, different door
Twitch runs the equivalent process through Amazon's tax interview — the same treaty logic applies, and the same money leaks if it's wrong. If your payout statements show US tax withheld and you're a UK resident, something needs fixing.
And the UK side
Your AdSense income remains fully taxable in the UK either way — the treaty stops double taxation, it doesn't make anything tax-free. Where some US tax genuinely was withheld, relief may be available against your UK bill; that's a conversation for your accountant (hello).
