Please select the appropriate Taxpayer Identification Number (EIN or SSN) type and enter your 9 digit ID number . These instructions supplement the instructions for Forms W8 BEN, W8 BENE, W8 ECI, W8 EXP, and W8 IMY.The company I am dealing with requested for a W-9 form. However, upon research I found out that I am supposed to submit a W8 form instead of a W9. Form W9 is a commonly used IRS form for providing necessary information to a person or company that will be making payments to another person or company. The revised 2024 form breaks off a new line 3b, adding an additional checkbox for entities that indicate in line 3a (former line 3) that they are a partnership. Foreign vendors do not complete the Substitute Form W-9; foreign persons or entities must submit one of five available forms. To do so, the FFIs need confirmation from you about whether you are a US tax resident or nonresident. Form W9 is only for US individuals. If you are a non-US individual then you need to be completing a W8.
