US government missing out on up to $250B in cost savings due to unimplemented recommendations: GAO

The U.S. Government Accountability Office finds the federal government could unlock up to a quarter-trillion dollars in savings if lawmakers and agencies act on the GAO's outstanding recommendations aimed at reducing waste and improving efficiency.

In a new report released in May, the GAO estimated that addressing its open recommendations “could produce between $132 billion and $251 billion in measurable financial benefits,” underscoring what it describes as a persistent gap between identified reforms and actual implementation.

The nonpartisan congressional watchdog also emphasized that implementation of its recommendations since 2002 has generated about “$1.51 trillion in financial benefits,” including direct savings, cost avoidance and revenue increases.

For fiscal 2025 alone, the GAO said, it issued more than 1,800 new recommendations spanning federal programs from defense acquisition and healthcare payments to infrastructure and information technology management. 

The agency argued many of these proposals target long-standing inefficiencies that continue to drain taxpayer resources.

“Our annual Duplication and Cost Savings report, High Risk List, and letters to the heads of agencies highlighting priority recommendations for their attention provide opportunities for Congress and agencies to increase financial benefits,” the watchdog reported.

One of the largest opportunities highlighted in the report involves Medicare payment reform. GAO noted that equalizing payment rates between physician offices and hospital outpatient departments “could save an estimated $156.9 billion over 10 years,” making it one of the most significant cost-saving measures.

The report also pointed to additional high-cost areas, including federal broadband deployment for emergency communications systems and ongoing challenges in Navy shipbuilding programs, both of which GAO identifies as recurring sources of cost overruns and schedule delays.

Across multiple areas, GAO stressed that many recommendations remain unimplemented despite being repeatedly raised in prior reports, limiting the federal government’s ability to achieve additional savings.

The GAO does not set policy, but it follows the implementation of its recommendations to avoid duplication, improve oversight, and strengthen performance of federal programs.
