How to Win Internal Revenue Service Contracts: A Contractor's Guide
Internal Revenue Service is one of the most-searched federal agencies — and one of the most competed. This guide covers what the IRS procures, where they post opportunities, how their proposals are evaluated, and how GovCon helps you write winning responses.
About Internal Revenue Service
The IRS procures IT modernization programs, data and analytics services, taxpayer contact-center operations, professional services, and facilities support. As one of the largest components of the Treasury Department by acquisition spend, the IRS routinely issues RFPs and task orders against agency-wide IDIQs and GWACs (NAICS 541512, 541519, 561422).
Where the IRS Posts Opportunities
SAM.gov, GSA Multiple Award Schedule and GWAC vehicles (Alliant, 8(a) STARS), and Treasury / IRS procurement portals for active RFPs.
If you're not already monitoring these channels, WinAContract aggregates live opportunities across SAM.gov and federal posting sites — including Internal Revenue Service contracts — so you don't miss anything relevant. Searching is free.
What the IRS Proposals Are Like
Federal civilian agency procurement under the FAR is increasingly run through contract vehicles such as GSA Multiple Award Schedules, GWACs, and agency IDIQs. Non-price factors — technical approach, past performance (CPARS), and Section 508 accessibility — typically count for the majority of the evaluation under best-value tradeoff, though some requirements are awarded LPTA.
Evaluation Factors You'll Face
- Technical approach (typically weighted heaviest)
- Past performance (CPARS)
- Section 508 accessibility
- Small business participation and set-asides (FAR 52.219-9)
- Management approach and key personnel
- Price and best value
Non-price factors typically outweigh price under best-value tradeoff, though LPTA awards turn on lowest price among technically acceptable offers. Proposals that score well are specific, evidence-based, and quantified, with clear strengths the evaluators can cite. Generic capability statements rarely win.
How to Write a Winning Proposal for the IRS
