UNSPSC 93161700: Tax administration

UNSPSC 93161700 Tax administration is a Class code covering the full spectrum of tax compliance, collection, and revenue-management services that state and local governments procure to support property tax sales, delinquent tax recovery, sales tax audit and analytics, arbitrage rebate compliance, unclaimed property auditing, and related administrative functions. Recent state and local opportunities show substantive demand across multiple issuing bodies—cities, counties, school districts, and state revenue departments—all seeking specialized vendors to handle high-stakes tax operations that blend legal, financial, and technical expertise. The code captures work ranging from online municipal tax lien sales platforms and delinquent property tax collection through litigation to comprehensive sales tax recovery programs and unclaimed property auditing conducted across multiple counties or states.

Issuing bodies include municipal treasurers and comptrollers (the City of Newark, New Jersey; City of Brownsville, Texas; Collier County, Florida), county sheriff's offices and tax assessment departments (Fulton County, Georgia; Bryan County, Georgia), independent school districts (Wimberley Independent School District; Paris Junior College), and state revenue or commerce departments (Washington State Department of Revenue; Texas Department of Public Safety). Geographic activity spans the Northeast (Newark, Connecticut), Southeast (Florida, Georgia), and Pacific Northwest (Washington State), with Texas school districts and municipalities representing a secondary concentration. Representative recent opportunities include Newark's RFP 2026-15 for online tax sales services (proposals due July 28, 2026) requiring vendors with prior internet-based municipal tax lien sales experience in multiple states, evaluated 35% on cost and fee compliance, 30% on technical platform functionality, and 35% on qualifications and cybersecurity posture; Fulton County's RFP 26RFP1600540B-PS for delinquent tax sales preparation services including title examinations and legal notice preparation (proposals due June 11, 2026, with MBE/FBE subcontracting targets of 16.83% and 3.41%); the City of Brownsville's RFQ for sales tax audit, compliance, and revenue enhancement services (qualifications due May 20, 2026); and the Washington State Department of Revenue's dual RFPs (responses due June 5 and June 15, 2026) for unclaimed property auditing across five counties, compensating successful bidders at ten percent of property value delivered to the state with a three-year maximum appropriation of $2 million. Contingency-fee structures dominate delinquent tax collection engagements (Wimberley ISD, Paris Junior College), while fixed-price and performance-based models govern online platforms, arbitrage services, and auditing work.
