What XTB says about the W-8BEN form
Almost everything written about this form is written about you — your residence, your treaty, your return. This page is written about the broker: what XTB Limited (UK, FCA FRN 522157) states in its own documents about taking the form and withholding at source. That is the part that can be verified, and the part that differs between brokers.
Which entity this covers
Read off the XTB help centre. The same article is published word for word under the Cypriot arm as well, so the wording is not specific to one of them. Two things this check did not establish. XTB states nowhere in its help centre whether it withholds US tax at source — the closest it comes is that a lower rate applies from the month after the form is approved, which is about timing rather than about who withholds. And it names no single rate: its own article says a reduced rate is "in most cases 15% instead of 30%" and immediately adds that it "can be different than 15%", so there is no figure to quote as the broker's. A third XTB entity is excluded outright — the form "is not currently available to XTB International Limited clients".
What this page does not answer
Not what you will pay, not which treaty rate applies to you, and not what to put on your own tax return. Those depend on where you are resident and on the agreement between your country and the United States — questions a broker's documents cannot settle and we hold no source for. Everything below is a statement by the broker about the broker.
