This is a Substitute Form W-9 document issued by Greenville County, South Carolina, revised in October 2022, which serves as the required taxpayer identification form for vendors and contractors conducting business with the County. The form captures essential vendor information including legal name, Doing Business As (DBA) or trade name, taxpayer identification number (either Social Security Number or Employer Identification Number/Federal Identification Number), legal address, entity tax classification, and the type of service to be provided. The document requires vendors to select their entity classification from options including individual/sole proprietorship, partnership, various LLC structures, C Corporation, S Corporation, trust/estate, or other designations, and to specify the service category such as medical/veterinarian, legal/attorney, rental of real property, or products/services. The form mandates provision of payment remittance information including a separate mailing address if different from the legal address, along with contact details comprising name, telephone, fax, and email.

The document functions as a certification form in which vendors attest under penalties of perjury that the taxpayer identification number provided is correct, that they are not subject to IRS backup withholding (or have been notified that such withholding no longer applies), and that they are a U.S. citizen or other U.S. person. The County emphasizes that failure to provide the required information in a timely manner could prevent or delay payment to vendors. This substitute form replaces the standard IRS Form W-9 for all County procurement activities and must be completed and signed by the vendor before contract award and payment authorization can proceed.
