In this lesson, ComplyPro discusses the Form W-8IMY, which is provided by non-U.S. entities acting as intermediaries or flow-through entities. It is used when receiving reportable amounts or withholdable payments on behalf of others. The form is typically used by foreign partnerships, foreign trusts, or foreign entities acting as intermediaries. Intermediaries must provide information about the beneficial owners, including withholding statements and tax documentation. Unlike the W-8BEN and W-8BEN-E, the W-8IMY has indefinite validity, but associated withholding certificates, evidence, and statements must be updated as required. The form requires a signature, and certifications should not be altered.
