This is a Substitute Form W-9 issued by the County of Greenville, South Carolina, for use in connection with a tax software procurement opportunity. The form is a vendor qualification document that requires bidders to provide their legal business name, taxpayer identification number (either SSN or EIN/FIN), entity tax classification, and service type information. Vendors must complete all required sections including legal address, payment remittance information, contact details, and certification statements affirming the accuracy of their taxpayer identification number and U.S. person status. The form specifies that vendors must select their entity classification from options including individual/sole proprietorship, partnership, corporation, trust/estate, or other designations, and must identify the type of service provided. The form was revised in October 2022 and explicitly states that the IRS Form W-9 will not be accepted as a substitute.

The Greenville County Tax Software procurement seeks to replace aging tax and auditor software systems with a package capable of accommodating the County's specific size, legislative requirements, and unique operational needs compared to surrounding states. The County requires strong and responsive vendor support available through multiple channels including phone, email, and ticketing systems, with vendor engagement expected throughout planning, implementation, and ongoing support phases. Vendors currently serving other counties within South Carolina are preferred. The Substitute Form W-9 serves as a mandatory vendor registration document to establish the contractor's tax status and payment information prior to contract award and execution.
