The Pentagon has failed eight straight audits. Its plan for the legal 2028 deadline is to change what passing takes.

The finding, in one paragraph: Congress converted the Pentagon's audit from an aspiration into a statute — Section 1005 of the FY2024 defense authorization act requires an unmodified opinion on the department's financial statements by December 31, 2028 — and the Department of Defense, having failed the audit every year it has been attempted, has responded not by accelerating the repair of its internal controls but by redesigning the campaign around the opinion itself: centralize command of the audit, throw large manual samples and artificial intelligence at proving the balance-sheet line items, and defer the control deficiencies — the things that make the numbers wrong in the first place — for at least two years.▸ The Government Accountability Office took that plan to Congress in May with a question that is polite, technical, and devastating: even if this works by 2028, what exactly will have been achieved, and can it be sustained the year after?

Five documents, read directly.▸ The centerpiece is GAO's testimony to House Oversight, DOD Financial Management: Questions Associated with New Financial Audit Approach (GAO-26-109115, May 13, 2026). The audit history comes from the DoD Inspector General's own explainer, Part 2: Understanding the Results of the Audit of the FY 2024 DoD Financial Statements (DODIG-2025-112), and the FY2025 result — the eighth consecutive disclaimer, issued December 2025 — from DOD's FY2025 Agency Financial Report as cited in the GAO testimony. The consolidated-government stakes are in GAO's audit of the FY2025 U.S. government financial statements, where DOD is the lead reason the United States, alone among major economies, cannot get an opinion on its own books. The mandate is Section 1005, P.L. 118-31, and GAO's September 2025 remediation-status report supplies the progress measurement.

The Department of Defense spends more than $1 trillion a year and holds 82 percent of the federal government's physical assets — the President's FY2027 request is $1.5 trillion, a 44 percent jump.▸ None of it has ever been through a passed audit. The department-wide disclaimers rest on component results, and the components split almost exactly down the middle:

The clean side includes the Marine Corps — the first military service ever to pass, now three years running — plus the retirement funds and smaller agencies.▸ The disclaimer side is the Army, Navy, and Air Force general funds and working capital funds: the overwhelming bulk of the money. In FY2024 the department booked $245 billion in accounting adjustments that were not supported or properly documented — entries made to force the books to agree, with no evidence behind them. The DoD OIG counts 26 material weaknesses in FY2025, six of them in IT systems; GAO's flat summary is that the department "has made only limited progress in addressing its material weaknesses since 2021."

Every audit failure generates Notices of Findings and Recommendations — specific defects with instructions to fix them. Here is what happens to them:

Eighty-one percent of the 2,912 findings were reissued because the components did not fix them.▸ The first audit, in FY2018, produced 2,595 findings and 20 material weaknesses; seven years and eight audits later the totals are 2,912 and 26. The machine finds the defects; the defects persist. That is the trajectory the 2028 statute collided with — and the context for what DOD did next.

In early 2026, DOD announced its revised approach: centralized coordination, and — in GAO's words, read to Congress — "prioritize supporting material line-item balances with evidence over resolving each material weakness and Notice of Findings and Recommendations," using "manual testing of large samples and using artificial intelligence tools."▸ Read the statute against the strategy. The law demands a clean opinion; a clean opinion attests that the statements are fairly presented — it does not attest that the systems producing them work. DOD's plan targets the former precisely. GAO's enumerated questions: the plan "would not prioritize remediating key internal control deficiencies for at least two years"; it is unclear whether the "resource-intensive" manual effort can be sustained past 2028; and open items include fraud risks, trained-staff availability, and the six IT material weaknesses — the ones the DoD OIG says directly impede a clean opinion. GAO's caveat to Congress: the approach "may help DOD meet its goal... However, doing so without addressing these underlying control issues may leave DOD at continued risk of ineffective and inefficient use of its resources."

There is precedent for the distinction.▸ The Marine Corps' clean opinions came the other way — years of transaction-level cleanup — and its FY2023 first pass took an extended audit and enormous manual effort to evidence balances its systems couldn't produce. The new approach generalizes that brute force to the whole department, on a deadline, minus the control fixes.

The FY2026 audit is underway now under the revised approach; its result — the ninth opinion — lands in December 2026, two audit cycles before the statutory deadline.▸ Section 1004 of the same law already attaches money to component non-participation (1.5 percent of certain unobligated funds). GAO's related ongoing work continues, and DOD's business-systems modernization — on GAO's High-Risk List since 1995 — remains the load-bearing fix: the DoD OIG has reported the systems efforts are "not complete or aggressive enough" to comply by 2028. The department's own remediation plans project retiring 89 legacy systems, with claimed savings of at least $760 million a year through FY2029.

All figures are from the five documents cited in-line, each read directly. The $245 billion is an absolute value of unsupported adjustments, not a loss estimate. Component-opinion counts are DoD's FY2025 AFR as cited by GAO.
