Why It Matters

The Government Accountability Office's 16th annual report on federal duplication and overlap identifies 610 unresolved matters that could yield $100 billion or more in additional financial benefits if addressed.

Since 2011, Congress and federal agencies have resolved roughly 77 percent of the 2,148 matters GAO has flagged across its annual reports, yielding approximately $774.3 billion in cost savings and revenue increases. Yet inefficiencies persist: inconsistent program performance, wasted taxpayer dollars, barriers for citizens accessing services, and heightened risks of fraud and waste.

The Big Picture

GAO's analysis identifies cascading risks across federal operations. Agencies lack consistent information about whether their programs work. Costs balloon or resources get used inefficiently. Citizens encounter barriers navigating overlapping services. The door opens wider for fraud, waste, and abuse. Specific opportunities illustrate the scale.

For example, improved health care resource sharing between the Department of Veterans Affairs (VA) and Department of Defense (DOD) could potentially save tens of millions of dollars annually.

The Department of Energy's (DOE) evaluation of nuclear waste classification could potentially save tens of billions of dollars.

Improving Navy shipbuilding acquisition practices could yield billions of dollars in cost savings.

FirstNet, the nationwide public safety broadband network, could generate $15 billion in financial benefits over 15 years with proper reauthorization.

Verifying income information for borrowers in the Student Loan Income-Driven Repayment Plan could recover more than $2 billion over 10 years.

Of the 82 open matters GAO identified as candidates for legislative solutions, 30 (about 37 percent) had legislation introduced in the 118th or 119th Congress, but as of early 2026, none had been enacted. That leaves 70 percent of those matters in the category of "agency recommendations" or "congressional considerations" without a clear legislative pathway forward.

GAO's authority to conduct this annual review comes from Public Law 111-139, Section 21, codified at 31 U.S.C. § 712 Note. The statute requires the agency to report annually on federal programs, agencies, offices, and initiatives with potentially duplicative goals or activities.

The Bottom Line

The Trump administration and Congress face a choice: continue the pattern of incremental action that has yielded $774.3 billion in savings over 15 years, or accelerate resolution of the remaining 610 matters to unlock the estimated $100 billion in additional benefits.
