About this agency
The Government Accountability Office, a civilian independent agency, procures support services, facilities management, reporting, technology, and consulting work to sustain its operations as Congress's principal auditing, evaluation, and investigative entity. GAO operates a centralized contracting apparatus that awards directly to prime contractors serving the agency's internal needs rather than functioning as a pass-through funding vehicle for external programs.
GAO has issued 3,111 federal contract awards since April 2005, with a combined potential value of $2.13 billion and $1.64 billion obligated to date. Recent activity shows 191 awards in 2022, 185 in 2023, 194 in 2024, 161 in 2025, and 160 so far in 2026, reflecting relatively stable annual volume in the low-to-mid 190s with a modest decline in the last two years. The agency works with 640 distinct prime contractors across its portfolio history.
Among recent primes, the competitive landscape is fragmented by award count. Emcor Government Services, Inc. leads with 144 awards and $103.9 million combined potential value, followed by Heritage Reporting Corporation with 60 awards (potential value $142 thousand), and Four Points Technology, L.L.C. with 47 awards and $62.2 million combined potential value. The top five by-count primes hold 35 percent of recent awards; however, concentration by potential value is highly fragmented, with the top five holding only 9 percent of combined potential value across the last five years. This divergence signals that GAO's largest prime by award volume (Emcor) commands substantial dollars, but the dollar distribution across the contractor base remains dispersed. The agency awards heavily through open competition — 79 percent of all awards carry no set-aside designation. Small-business set-asides account for 7 percent of awards, with 8(a) sole source (1 percent), HUBZone, service-disabled veteran-owned small business (SDVOSB), and women-owned small business (WOSB) each below 1 percent.
The most recent recorded award date is December 15, 2026. GAO's contract activity reflects steady, consistent procurement of services and support across a broad vendor base rather than concentration among a few strategic primes, and set-aside participation remains modest relative to open competition.
Description
The Government Accountability Office gathers information to help Congress determine how effectively executive branch agencies are doing their jobs.
