About this opportunity
The Internal Revenue Service (IRS) issued a Limited/Sole Source Justification Notice for a six-month bridge contract awarding Taxpayer Experience Engineering Support to TrussWorks, Inc. The contract, valued at $2,266,665.80 and awarded on December 11, 2025, provides critical IT services and engineering support for high-volume, mission-critical web applications including the Data Authorization and Transfer Service (DATS) and Tax Withholding Estimator (TWE 2.0) to ensure operational readiness for the 2026 filing season. The IRS justified the sole-source award under urgent and compelling circumstances, citing TrussWorks' existing deep knowledge of specialized taxpayer-facing tax applications and the estimated 90-day transition period required to onboard a new vendor to meet the pressing filing season timeline. The agency acknowledges this as a bridge procurement and has committed to conducting market research with plans to release a competitive solicitation targeted for June 1, 2026, which will include a Sources Sought/RFI, draft Performance Work Statement (PWS) development, and vendor engagement to enable full competition in subsequent procurements.
