UNSPSC 93161600: Taxes other than income tax

UNSPSC 93161600 Taxes other than income tax is a Class code covering motor vehicle tax compliance audits and related tax administration services that state and local governments use to identify and recover revenue from vehicles improperly registered out-of-state or unregistered in violation of local property tax statutes. Recent solicitations show municipalities and state tax departments procuring external audits to detect tax evasion, recover lost revenue, and maintain accurate tax rolls. The issuing bodies include city assessor offices and state revenue departments, which solicit RFPs for specialized audit and compliance services to supplement or manage tax administration functions.

Connecticut municipalities drive recent activity under this code. The City of Meriden, Connecticut posted RFP 02731 on October 9, 2026, for a comprehensive motor vehicle audit due October 30, 2026, targeting vehicles registered out-of-state by Meriden residents to avoid local property tax, with vendor questions due October 23, 2026 through the OpenGov EPortal. The City of Stamford, Connecticut issued RFP 2027.0065 for Motor Vehicle Tax Compliance services on August 20, 2026, with proposals due September 17, 2026, managed through ProcureWare and the Deputy Assessor's office. The Rhode Island Department of Revenue, Division of Taxation, conducted RFI 27006865 on July 29, 2026, due September 11, 2026, for broader tax administration systems integration (an information-gathering exercise with no award to follow), indicating state-level interest in consolidated tax system infrastructure. Connecticut shows the strongest recent concentration of motor vehicle tax compliance RFPs, with two municipalities in the same state pursuing similar audit services within weeks of each other, suggesting emerging municipal focus on property tax base recovery.
