New Vendor W9 Policy


The Internal Revenue Service requires all vendors to have a valid taxpayer identification number. Prior to this policy's creation, the college did not have a consistent method of ensuring compliance.


This policy seeks to ensure compliance with the law by requiring new vendors to self-report their taxpayer identification number. It also protects the college by requiring all vendors to be approved before receiving payment from the institution.


All vendors must complete a New Vendor Request/Substitute W-9 form (Individual or Business) to be added as a vendor.

Administration of Policy

The controller/director of business services shall oversee this policy and review it at least once every two years. Changes to this policy shall be made in accordance with the college's Policy on Policies.

Forms can be found on the Business Services webpage. These forms are for U.S. residents only; foreign nationals must fill out the Foreign National Form found on the Business Services webpage.
