The W-8ben Non-Resident Alien Checklist is an important document for nonresident aliens who receive income from sources within the United States. This form helps to establish that a nonresident alien is not a U.S. citizen or resident for tax purposes and allows them to claim any applicable tax treaty benefits. The form requires the completion of several sections which include identifying information, certification of a permanent residence outside of the U.S., certifying the individual’s status as a student or business apprentice, and providing evidence of foreign status if required by the IRS. By completing this form, nonresident aliens can prove their foreign status and receive the appropriate tax treaty benefits, such as reduced withholding on certain types of income.
