Revenue Service Technologies LLC

Revenue Service Technologies LLC Software Consulting Division operates exclusively as a subcontractor to federal systems integrators and consulting firms, delivering Unisys mainframe operations support, IRS modernization services, and enterprise systems development for the Department of the Treasury's Internal Revenue Service (10 of 11 awards). The company is a minority-owned, Asian-Indian American-owned small disadvantaged business organized as a limited liability company, based in Davidsonville, Maryland, and operates solely on sub awards with zero prime positions across its recent federal footprint.

Revenue Service Technologies' customer concentration is complete: the Department of the Treasury (Internal Revenue Service) anchors 91% of awards, with one supplementary Treasury Departmental Offices sub award. This concentration reflects the vendor's specialization in IRS-centric modernization work. The vendor places work under five parent vehicles, with the most significant activity on Indefinite Delivery Contract 2032H523D00001 (4 task orders) and Alliant II (4 task orders), followed by the GSA Multiple Award Schedule (2 task orders), the IRS Enterprise Development Operations Services contract (2 task orders), and Solutions for Enterprise Wide Procurement V (1 task order).

Revenue Service Technologies' subcontracting portfolio centers on three prime relationships. Science Applications International Corporation is the dominant prime, receiving five sub awards focused on Unisys mainframe modernization work: Integrated Data Retrieval System modernization (Unisys retirement and replacement initiative base and option period, with associated assemblies NRE), submission processing domain COBOL developer support, and enterprise computing center Unisys Clearpath Dorado mainframe operations and maintenance. Deloitte Consulting LLP and Maximus Federal Services, Inc. split the remainder: Deloitte engages the vendor on Long Term Integration Support (LTIS) deliveries for the Individual Masterfile Modernization (IMF MOD) program (two awards dating to 2024 and 2025), while Maximus uses Revenue Service Technologies for Business Objects Enterprise support on Passport and Private Debt Collection systems operations and maintenance, and for .NET development on the Custodial Detail Database development effort. Recent work includes a September 2026 tax account processing and business tax account data store sub award from Accenture Federal Services and a May 2026 LTIS 2032H5-21-F-00043 CADE2 follow-on delivery order from FCN, Inc.

Activity has accelerated recently, growing from one award in 2021 to six in 2026. The SCI dataset shows between 5.0 and 9.0 FTEs delivered to federal customers across FY2022–FY2025, reflecting a labor-centric subcontracting model centered on specialized Unisys mainframe and IRS systems expertise. All category concentration falls under NAICS 541512 (Computer Systems Design Services). As a pure subcontractor with no prime position, Revenue Service Technologies feeds primary integrators and consulting firms rather than competing for direct federal work; this positioning suggests the vendor functions as a specialized labor supplier for legacy IRS systems modernization and enterprise operations support.
