This is a substitute Form W-9 document issued by the County of Greenville, South Carolina, for use by contractors and vendors conducting business with the county. The form requests standard taxpayer identification information including legal name, DBA/trade name, taxpayer identification number (either SSN or EIN/FIN), and legal address. Vendors must select their entity tax classification from options including individual/sole proprietorship, partnership, corporation, LLC, trust/estate, or other designations, and must specify the type of service provided such as medical/veterinarian services, legal/attorney services, rental of real property, or products/services. The form also requires a separate payment remittance address, contact name, telephone, fax, and email information. Contractors must certify under penalty of perjury that the taxpayer identification number provided is correct, that they are not subject to backup withholding by the IRS, and that they are a U.S. citizen or U.S. person. The form must be signed and dated by the vendor, with the county noting that failure to provide the required taxpayer identification information in a timely manner could prevent or delay payment.

The Greenville County substitute W-9 form is mandatory for all vendors seeking to do business with the county and cannot be replaced with the federal IRS Form W-9. This form is a prerequisite document that must be completed as part of the vendor registration and payment processing requirements for any state or local contract opportunity with Greenville County, including the Twin Chimneys Landfill earthwork project. The form was last revised in October 2022 and serves as the county's standard method for collecting vendor tax identification and remittance information necessary for compliance with federal tax law and the county's accounts payable processes.
