How to fill youtube tax form for uk creators to avoid 30 percent tax 2026

UK creators avoid the default 30% US withholding by completing the US tax info section inside AdSense — specifically filing a W-8BEN form and entering your UK Unique Taxpayer Reference as your foreign TIN. That filing claims the benefits available under the US-UK Double Taxation Treaty, which can bring the withholding rate down to 0%. Inside AdSense, under 'Manage tax info,' select 'Yes' for the tax treaty claim and choose United Kingdom from the country dropdown. This only adjusts what's withheld on US-source income at the point of payment — you still need to declare your full YouTube earnings to HMRC on your annual UK tax return to stay compliant on the domestic side.
