GAO Building

GAO provides Congress, the heads of executive agencies, and the public with timely, fact-based, non-partisan information that can be used to improve government and save taxpayers billions of dollars. In fiscal year 2013, GAO reaped $51.5 billion in financial benefits and helped make the government more efficient in 1,314 other ways. GAO’s annual performance and accountability report provides more details. 

GAO’s work is done at the request of congressional committees or subcommittees or is statutorily required by public laws or committee reports, per our Congressional Protocols. GAO also undertakes research under the authority of the Comptroller General.

For more information about GAO’s other services specifically for Congress—such as general assistance and briefings by GAO experts—please see our Watchdog website (accessible through the congressional computer network).
