What is Form W-8 and does it apply to me?

IRS W-8 Forms are a group of tax forms specifically for non-resident aliens and foreign businesses who have either worked in or earned income in the US. It declares the applicant’s status as a non-resident alien or foreign national and informs financial companies that they will be taxed differently than a resident. These forms are only for foreign people and entities without citizenship or residency. A brief description of each form is listed below. Please refer to the instruction forms for specific details about each W-8 form.
