Mainframe Tax Support Services

Salt Lake County Information Technology is soliciting proposals for comprehensive Mainframe Tax Support Services through a Request for Proposals (RFP) targeting firms capable of supporting their aging mainframe-based Tax System. The procurement seeks a contractor to provide full application operations, system troubleshooting, incident resolution, routine updates, user support, and CICS application online support for a complex system comprising approximately 2 million lines of COBOL and Natural code across 2,600+ programs, 154 DB2 tables, and 65 VSAM files. Key deliverables include business process mapping, knowledge transfer, documentation development, and transition planning for a system supporting 70 daily online users with 50-60 batch jobs. The evaluation criteria will allocate 70% weight to program proposals and 30% to pricing proposals, with proposers required to demonstrate relevant experience in local government tax systems. Critical dates include a pre-proposal WebEx meeting on December 2, 2025, final question submission deadline of December 4, 2025, and proposal submissions due by December 18, 2025, through the Utah Public Procurement Place (U3P) Bonfire system, with committee meetings scheduled for January 8, 2026, and proposer interviews on January 22, 2026.

The contract will have an initial three-year term with potential for two additional one-year terms, potentially extending to five years total, with the new mainframe replacement system expected to be operational by January 1, 2029. Proposers must provide professional liability insurance of $1,000,000 per occurrence, commercial general liability of $500,000 per occurrence, and cyber liability insurance of $1,000,000 per loss. The County reserves the right to apply preference adjustments for employee health care benefits and veterans/companywide hiring practices. While no specific set-aside designations are mentioned, proposers must submit comprehensive proposals in three separate PDFs: a Program Proposal (limited to 25 pages), Pricing Proposal, and optional Supplemental Attachments. Contractors must comply with strict data privacy requirements, security standards, and comprehensive incident reporting protocols, including immediate 24-hour reporting of any security breaches. Although no specific budget range is detailed, the complexity of the system and required support suggest a substantial contract value commensurate with maintaining a critical tax processing infrastructure serving Salt Lake County.
