Joint Enterprise Tax Calculator Solution (JETCS)

The Internal Revenue Service is conducting market research for a Joint Enterprise Tax Calculator Solution (JETCS) that will be integrated into IRS workflows to support examiners’ complex tax‑calculation needs. The effort, identified under NAICS 541519 and 541512 and PSC DA01, requires a tested, innovative tax‑calculator platform with a user‑interface for viewing and editing returns, the ability to perform diverse calculations across published and pre‑published IRS forms, schedules, and worksheets, and to incorporate annual legislative indexing as well as ad‑hoc legislative changes. The solution must support a 10‑year rolling tax window, provide accurate, traceable, and transparent results for single‑year, multi‑year, and multi‑form computations (including penalties and interest), and be either stateless or stateful as described in a detailed architecture diagram. Contractor responsibilities include system integration and performance, ongoing operations and maintenance (updates, stakeholder coordination, testing, troubleshooting, performance monitoring, and annual security controls assessments), compliance with IRS and federal security requirements, and provision of calculation software licensing and support. The contract will be a 12‑month base period with four additional 12‑month options; responses to the Sources Sought Notice (SSN 26‑25‑A‑PMO‑JETCS‑SSN) are due May 12, 2026, and the government is also seeking recommendations on the most appropriate strategic‑sourcing vehicle for this requirement.
