What documents are required to update my W-8BEN?

Apart from the W-8BEN tax form itself, a valid passport, driver’s license, or other government photo ID is required to process the W-8BEN. If your address has changed since you last updated your W-8BEN, you will be asked to submit an address change form and a recent utility bill to verify your new address. Joint accounts require that separate W-8BENs be submitted by both account holders.
