Pennsylvania W-9 Form and Information for Suppliers
A W-9 form is an IRS form used by a company to request your Taxpayer Identification Number (TIN) and certification. The TIN and Legal Name provided during the registration process must match the W-9 in order to receive a contract or payment. The Payable Services Center will validate that a match exists between the registration and the W-9 form.
Another critical step in the Commonwealth’s validation process is the entry of accurate bank information in the Edit Bank Data & Product Categories page, accessible to logged in Administrative Users. As a supplier capable of receiving payments, this information MUST be completed prior to submission of the W-9 form. You can access this page on the left navigation after you are logged onto the PA Supplier Portal.
Ensure the ACH Banking Information is accurate prior to submission of the W-9 form.
