What Form W-8BEN does

Foreign individuals give Form W-8BEN to a US payer or broker to certify they're not US persons and, where a tax treaty applies, to claim a reduced rate. Without it, US-source income such as dividends, interest, rents and royalties paid to foreign persons is generally subject to 30% withholding (IRS Instructions for Form W-8BEN). Many treaties cut the rate on dividends to 15% or less, and on some royalties or interest to 0%.

Filling it in

Businesses use Form W-8BEN-E instead. US persons use the W-9.
