2,148 Recommendations.
$774 Billion Saved.
Congress Just Has to Read the Memo.
On May 12, 2026, the Government Accountability Office released GAO-26-108505 — its 16th annual report on federal duplication, overlap, and fragmentation. The numbers are not subtle. Since 2011, GAO has identified 2,148 matters and recommendations for Congress and federal agencies. Of those, 1,662 (77%) have been fully or partially addressed. The cumulative haul: roughly $774.3 billion in realized financial benefits.
The 2026 report adds 97 new recommendations in fragmentation-and-overlap reform alone — on top of the 1,833 new recommendations GAO issued across all of FY 2025, against a fiscal-year financial-benefit haul of $62.7 billion. Across the remaining open items, GAO estimates Congress and agencies could capture between $132 billion and $251 billion in additional future savings. The recommendations are public. They are itemized. The math is done.
What Congress has to do is read the memo. A 77% closure rate sounds high until you notice which 23% is still open. The unfinished items are not paperwork. They are the largest-dollar reforms in the GAO inventory — Medicare hospital-outpatient payment equalization (~$157 billion over a decade per CBO scoring), ineligible-dependent purges from Federal Employees Health Benefits, IRS enforcement modernization, and the underlying machinery responsible for $186 billion in improper federal payments in FY 2025 alone.

Release date: May 12, 2026 (today). 16th annual GAO duplication, overlap, and fragmentation report.
Cumulative financial benefits: ~$774.3 billion since 2011 — a $49.3B increase over the May 2025 edition ($725B). The series covers congressional action plus federal-agency action on GAO-identified duplication and overlap.
Closure rate: 1,662 of 2,148 matters and recommendations (77%) fully or partially addressed. 486 items remain open in this work-stream alone — and that is before counting the broader open-recommendations inventory.
New in 2026: 97 fresh recommendations across roughly two dozen topic areas — including consolidating mission-support services (payroll, travel) across agencies, expanding DOD-VA healthcare resource-sharing, and standing up an FBI-led government-wide anti-scam strategy in place of the current 13-agency patchwork.
Money still on the table: $132 billion–$251 billion in additional future savings if Congress and agencies act on remaining open items.
“We've already shown that these recommendations can deliver real results — hundreds of billions in savings and improved services.”

The closed 77% is mostly small-to-mid-dollar agency cleanup — consolidating duplicative training programs, harmonizing data definitions, killing a redundant reporting line. Useful work. Not the story. The 23% still open is concentrated in the biggest-ticket reforms GAO has surfaced this century, the ones that require Congress, not just an agency memo. From GAO-25-108167 (the May 22, 2025 Recommendations for Congress report): of the 272 open congressional matters as of March 2025, 31 carry estimated financial benefits — and a single one of them is worth approximately $157 billion over a decade. That is the long-standing recommendation, traced through CBO and MedPAC analysis, to equalize Medicare reimbursement rates for identical procedures performed in hospital outpatient departments versus physician offices. GAO first flagged it in 2015. Eleven years later, Congress has not closed it.
Total: $186 billion in estimated improper federal payments in FY 2025 across 64 programs at 15 agencies. Up $24 billion from FY 2024.
Composition: ~$153 billion (82%) are overpayments. At least $10 billion are underpayments — money owed that didn't go out. The rest are payments where eligibility could not be determined.
Drivers: Medicare and Medicaid lead, followed by the Earned Income Tax Credit and SNAP. Together they account for the majority of the total.
Twenty-year baseline: Improper payments have been tracked since FY 2003. Cumulative estimated improper payments across the federal government over that span: roughly $3 trillion.
The connection: GAO has open recommendations on every one of these programs. Many trace back five, ten, fifteen years. The reason the FY 2025 number went up $24 billion instead of down is the same reason the FY 2024 number went up — Congress and the agencies didn't act on the open recommendations.
On February 25, 2025, Comptroller General Gene L. Dodaro testified before the House Committee on Oversight and Accountability on GAO-25-108125 — the 2025 High-Risk List. The list flagged 38 federal program areas at elevated risk for waste, fraud, abuse, or mismanagement — including one new entry, Improving the Delivery of Federal Disaster Assistance. Across the 19 fiscal years FY 2006–FY 2024, GAO-attributed financial benefits from addressing High-Risk Series items totaled nearly $759 billion, an average of $40 billion a year. Three areas regressed against GAO criteria in 2025: DOD Weapon Systems Acquisition, Improving IT Acquisitions and Management, and Managing Federal Real Property. Dodaro's tenure ended ten months later, on December 30, 2025, after 15 years as Comptroller General. Chief Operating Officer Orice Williams Brown has been serving as Acting Comptroller General since — pending Senate confirmation of a permanent successor nominated by President Trump.
A 77% closure rate is, by any honest measure, a high one. It is also misleading as a standalone statistic. The reason GAO's smaller recommendations close is that agency bureaucrats have the unilateral authority to close them — consolidate two training programs, retire an obsolete IT system, reconcile a data definition. The reason the largest dollar recommendations stay open is that closing them requires Congress to vote. The Medicare outpatient equalization. The Federal Employees Health Benefits ineligible-dependent purge. The IRS enforcement modernization. The Medicare/Medicaid fraud-prevention authorities. Every one of these is bigger than the entire DOGE cost-cutting agenda combined, and every one of them has been sitting in plain English in a GAO report for a decade or more. The political story is not that the watchdog is failing. It is that the recommendations are sitting on the desks of members of Congress who have not, for ten or fifteen years, been willing to take the floor vote.
GAO has handed Congress 2,148 specific cost-cutting recommendations since 2011 and $774 billion in already-realized savings to prove they work. Another $132–$251 billion in savings is sitting in the open file — plus $186 billion lost to improper payments last year alone. The watchdog did its job. The memo is on the desk. The only thing missing is the floor vote.
