What's New

Foreign Account Tax Compliance Act (FATCA).   FATCA requires a participating foreign financial institution to report all U.S. account holders that are specified U.S. persons. Form W-9 and the Instructions for the Requester of Form W-9 have been revised to expand the Exemptions box on the front of the form to include entry for the Exempt payee code (if any) and Exemption from FATCA Reporting Code (if any). The references for the appropriate codes are in the Exemptions section of Form W-9, and in the Payees Exempt from Backup Withholding and Payees and Account Holders Exempt From FATCA Reporting sections of these instructions.

  The Certification section in Part II of Form W-9 has been expanded to include certification of an exemption from FATCA reporting.

Payment card and third party network transactions.   References to payments made in settlement of payment card and third party network transactions have been added to the Purpose of Form section of Form W-9.
