KDP, paperback and audiobook royalties land in dollars, with US tax skimmed off the top. We sort your W-8BEN, reclaim what's yours, and report it all to HMRC the right way.
“Amazon is withholding 30% US tax — can I get that back?”
“My royalties come in dollars from abroad — how do I report that?”
“Can I claim editing, cover design and my ads?”
Publishing income has its own rules. Here's what we take off your plate.
US tax law defaults to withholding 30% on royalties paid to non-US residents. The UK–US tax treaty brings that to 0% — but only once a valid W-8BEN is on file with Amazon. On a $1,000 royalty payment:
| Royalty payment, no W-8BEN on file | $1,000 | The 30% US default withholding applies |
| US tax withheld | −$300 | Gone before the money reaches you |
| = What lands in your account | $700 | And you still owe UK tax on the income |
| Same payment, valid W-8BEN on file | $1,000 | 0% withheld under the UK–US treaty |
A W-8BEN costs nothing and takes minutes in KDP's tax interview — but it is generally valid only to the end of the third calendar year after you sign it, then it needs renewing. Let it lapse and the 30% quietly comes back.
By default the US withholds 30% on royalties paid to non-residents. As a UK author you can usually reduce this to 0% by completing a W-8BEN form, thanks to the UK–US tax treaty. We make sure it's filed correctly so you stop losing money.
Yes — your worldwide royalty income is taxable in the UK and must go on your Self Assessment, even if it's paid in dollars from the US. We convert and report it properly.
Editing, proofreading, cover design, formatting, ISBNs, advertising, writing software and research costs are typically allowable — reducing the profit you pay tax on.
Yes. Royalties are taxable income when you earn them, even if every penny goes straight back into ads. The ad spend is an allowable expense, so it reduces the profit you're taxed on — but it never removes the duty to declare. Authors who net the two off and report nothing are the ones who get the awkward HMRC letter.
