In this lesson, ComplyPro discusses the Form W-8BEN-E, which is used by foreign entities to document their status for chapter 3 and chapter 4 purposes. It is primarily used by corporations and complex trusts, but other entities like partnerships, disregarded entities, and simple or grantor trusts can also use it to make treaty claims as hybrid entities. The form allows withholding agents to rely on it for determining the status of a payment and applying reduced withholding rates. Failure to provide the form may result in 30% withholding. The form is valid for a specified period, requires a signature, and certifications should not be altered.
