What is a W8-BEN Form?
The W8-BEN Form, also called the Certificate of Foreign Status of Beneficial Owner for United States Tax Withholding & Reporting, is a form required by the IRS, similar to the W9 form that employees and subcontractors in the United States must submit to employers.
However, the W8-BEN differs from a W9 because it is filled out only by non-US residents who are receiving payments from individuals or companies in the United States.
