The Government Accountability Office's central fraud hotline processed more than 9,350 allegations of fraud, waste, abuse, and mismanagement of federal funds in fiscal year 2025, according to GAOverview: FraudNet Activity Report for Fiscal Year 2025 (GAO-26-108938). About a third of those tips, roughly 3,100, were referred to more than 60 outside entities, including the inspectors general who police the agencies that award and oversee federal contracts.
Background
FraudNet is GAO's public-facing intake channel for allegations involving the misuse of federal money and resources. The public, government employees, and contractors can submit tips through it, and GAO uses the channel to surface leads, support its own audits and investigations, and route credible allegations to the entities best positioned to act on them. The fiscal 2025 report is GAO's recurring accounting of that activity, published on June 24, 2026 and listed on the agency's reports and testimonies page.
The hotline sits at the front end of a sprawling federal oversight network. GAO does not prosecute or independently adjudicate most of what comes through FraudNet. Instead, it screens incoming allegations, performs research to test whether a tip has substance, and pushes qualifying matters to the agency or watchdog with jurisdiction. For the contracting community, that makes FraudNet a quiet but consequential pipeline: a single tip about a questionable invoice, an ineligible provider, or a diverted payment can become an inspector general referral, and from there an audit, suspension, or law-enforcement matter.
Key Details
The headline figure is volume. FraudNet processed over 9,350 allegations in fiscal 2025, drawn from members of the public, federal employees, and contractors. Of those, approximately 3,100, close to one-third, were referred onward to more than 60 entities. The report specifically names the Offices of Inspector General at the Departments of Agriculture, Defense, Health and Human Services, Justice, and Veterans Affairs among the recipients of those referrals. Those five departments collectively account for an outsized share of federal contract and grant spending, which is why their watchdogs are frequent destinations for FraudNet traffic.
Behind the referral count is a research function that does more than forward emails. FraudNet's research analysts ran over 900 commercial and law-enforcement database queries during the year, work that supported 10 GAO audits and investigations. Those queries help analysts corroborate identities, trace entities, and establish whether an allegation is worth elevating, the difference between a vague complaint and a documented lead.
The report offers a concrete illustration of how that work pays off. In one cited example, a FraudNet-supported GAO investigation of the Federal Employees Health Benefits program identified providers who were ineligible yet accepting FEHB patients. That finding points at an ongoing improper-payment risk inside one of the government's largest benefit programs, and it shows the chain in action: a tip and supporting research feeding a formal GAO investigation that flags a systemic vulnerability rather than a single bad actor.
The numbers also frame FraudNet's role in the broader anti-fraud architecture. With more than 9,350 allegations handled and roughly 3,100 referred, the bulk of incoming tips are screened out, consolidated, or resolved without a formal referral. That filtering is part of the point. The hotline's value to inspectors general is not raw volume but vetted leads, allegations that have already cleared an initial research pass before landing on an OIG's desk.
What It Means for Contractors
For companies doing business with the government, the report is a reminder that the reporting surface for misconduct is wider than the procuring agency itself. An allegation does not have to start with a contracting officer or a competitor's bid protest to reach an inspector general. It can begin with an anonymous tip to FraudNet from an employee, a subcontractor, or a member of the public, and the report makes clear that contractors themselves are among the parties who file these allegations.
The named recipients matter. Contractors working with the Defense Department, HHS, the VA, Agriculture, or Justice should assume that a credible FraudNet tip touching their work can land with the relevant OIG, the same offices that drive suspension and debarment actions, civil False Claims Act referrals, and audit findings that ripple into past-performance records. The FEHB example is instructive for health-care and benefits contractors in particular: eligibility and credentialing failures are exactly the kind of issue FraudNet's research function is built to surface.
The roughly 900 database queries underscore that referrals are not made blindly. By the time an allegation reaches an inspector general, GAO analysts have often already run commercial and law-enforcement checks against it. Contractors cannot count on a thin or unsupported complaint being dismissed out of hand; the screening step is designed to add evidence, not just pass tips along.
Practically, the report reinforces the case for internal controls that catch problems before an outside tip does. Robust documentation of invoicing, eligibility, subcontractor management, and labor charging is the most direct defense against an allegation that survives FraudNet's research pass and becomes an OIG matter. Companies that treat hotline exposure as a real channel, not a theoretical one, are better positioned to respond if a referral materializes. With over 9,350 allegations flowing through a single GAO intake point in one year, the channel is anything but theoretical.
