About this opportunity
The Internal Revenue Service (IRS), a civilian agency under the Department of the Treasury, issued a Justification for Other Than Full and Open Competition (JOFOC) for a sole source award of contract 205AE9-26-C-00007 on December 31, 2025, to procure the GoSystem Tax Calculator Software from Thomson Reuters Special Services LLC. The contract is structured as a 6-month Firm-Fixed-Price engagement designed to provide continuity in tax calculation capabilities for approximately 3,500 IRS Revenue Agents processing Form 1040 audit cases following an unexpected termination of the existing contract. The IRS justified the sole source award based on unusual and compelling urgency, noting that Thomson Reuters is the sole manufacturer of the current integrated tax calculation software and that pursuing competitive procurement would delay modernization efforts by nearly a year and jeopardize tax season readiness in January 2026. The procured solution requires cloud-based functionality, integration with Pega Applications, and APIs for complex tax calculations supporting all related Individual Income Tax forms and schedules. While the specific contract award amount was not disclosed in the available documentation, the IRS intends this short-term arrangement to serve as a bridge solution while competitive bids for a permanent, long-term replacement are solicited and evaluated.
