A W-9 is required for initial payments to businesses that are not identifiable as corporations, government agencies or tax-exempt organizations. If the type of business of a payee is not known, a W-9 must be obtained before payment. If a vendor/individual fails to accurately complete a W-9, Temple University is required by the Internal Revenue Service to withhold income tax at 31 percent. This amount will be deposited to an approved IRS depository bank and reported to the vendor or individual as federal withholding on a Form 1099 at calendar year-end.
