A UK-US treaty rate still needs paperwork before it becomes real at source

The hook

“A tax treaty does not usually reduce UK withholding by magic just because the taxpayer can quote the treaty article.”

HMRC's own materials point U.S. residents toward a real claim workflow, including form US-Individual 2002 for certain income streams and supporting treaty analysis under HS304. That means the practical issue is not only whether the treaty provides relief. It is whether the taxpayer has actually organised the claim in the way HMRC expects.

The takeaway

In treaty work, the missing form is often more expensive than the missing theory.
