W-9 SINGLE SHEET~4.pdf

This document is a W-9 tax form, which is a Request for Taxpayer Identification Number and Certification. It is required to be completed by contractors and vendors who wish to do business with the state of Illinois.

The W-9 form collects the contractor's or vendor's name, address, and taxpayer identification number, typically a Social Security Number or Employer Identification Number. This information is necessary for the state to properly report income and issue tax documents to the contractor or vendor. Completion of the W-9 is a standard requirement for contractors and vendors seeking to provide goods or services under a state or local government contract opportunity.
