100 Years of GAO
This year, the U.S. Government Accountability Office celebrates a century of service as a source of objective, non-partisan information on government operations. GAO plays a key role in helping Congress improve the performance of government, ensuring transparency and saving money. Join us as we celebrate our agency’s century of service to Congress and the nation.
As GAO celebrates a century of service, Comptroller General Gene Dodaro shares his thoughts on the agency’s legacy.
Our budget, strategic and performance planning, performance and accountability reports, and peer review results.
We support Congress in meeting its constitutional responsibilities, and help improve the performance and ensure the accountability of the federal government. We provide Congress with timely information that is objective, fact-based, non-partisan, nonideological, and balanced.

The Budget and Accounting Act of 1921 formed GAO to investigate all matters related to the use of public funds. The act also requires us to report on our findings and recommend ways to increase economy and efficiency in government spending.
