What Is the False Claims Act? (2026)
The False Claims Act is the federal government's primary tool for recovering money lost to fraud. It makes it illegal to knowingly submit false or fraudulent claims for government funds, and — unusually for a federal statute — it lets private citizens enforce it.
Introduction — What the FCA Actually Is
This page explains where the law came from, what it actually prohibits, how its qui tam provisions work, and why it has become the most powerful anti-fraud statute in the country. If you have seen conduct that might fit these patterns, our eligibility guide walks through the practical questions — whether your information is non-public, whether you are first to file, and what evidence you have.
The False Claims Act imposes liability on anyone who knowingly submits false claims, makes false records, conspires to defraud the government, or improperly avoids an obligation to pay money back — known as a "reverse" false claim. The word knowingly is important: the law does not require proof of intent to defraud. Deliberate ignorance or reckless disregard for the truth is enough, while honest mistakes generally are not.
For vocabulary that runs through this area, our legal glossary defines relator, seal, materiality, and other key terms in plain English.
The Qui Tam Provisions — How Citizens Enforce the Law
The feature that sets this statute apart is its qui tam provision, which lets a private person — a relator — file suit on the government's behalf. To In plain terms, qui tam is the mechanism by which an insider becomes the named plaintiff in a fraud case the government would otherwise never have known about.
When a relator files, the complaint is kept under seal, secret from the defendant and the public. The relator serves the government a confidential disclosure statement, and prosecutors investigate — often for well over a year — before deciding whether to intervene or let the relator proceed alone.
Most cases resolve by settlement rather than trial. See the full sequence on our case timeline page and reward details on whistleblower rewards.

A Law Born in the Civil War
The False Claims Act dates to 1863. During the Civil War, suppliers sold the Union Army defective rifles, sick horses, and rotten provisions while billing the government at full price. Congress responded with a statute that let private individuals sue fraudsters on the government's behalf and keep a portion of the recovery. It was nicknamed the "Lincoln Law."
The statute faded for decades, then was significantly weakened in the 1940s. The turning point came in 1986, when Congress overhauled it — raising penalties, strengthening whistleblower rewards, and adding anti-retaliation protections. The Fraud Enforcement and Recovery Act of 2009 broadened the kinds of conduct the Act reaches. By 2025 and 2026, the Act remains the Justice Department's leading source of civil fraud recoveries.
What the Law Actually Prohibits
At its core, the False Claims Act imposes liability on anyone who knowingly submits false claims, makes false records, conspires to defraud the government, or improperly avoids an obligation to pay money back. Common patterns in practice include:
In healthcare, that translates into upcoding, phantom billing, and medically unnecessary services — see concrete patterns on our Medicare fraud examples page, and real outcomes in our settlement case studies.
Penalties Under the Act
Liability is steep. A defendant can owe three times the government's actual damages, plus a per-claim civil penalty adjusted for inflation each year. Because large fraud schemes generate thousands of individual false claims, total exposure can climb into the millions or beyond.
That is precisely why settlements are common and why relator shares can be significant. A relator generally receives between 15% and 30% of what the government recovers, depending on how much the relator contributed and whether the government intervened.
Key penalty features:
- 1treble damages on the government's actual losses
- 2a per-claim civil penalty adjusted for inflation each year
- 3the relator's share of 15%–30% of the recovery
- 4settlement terms that may include compliance monitoring
How a Qui Tam Case Unfolds
When a relator files under the qui tam provisions, several things happen in sequence. This is the same machinery introduced on our home page and detailed on our case timeline page.
The typical sequence:
- The complaint is filed under seal, kept secret from the defendant and the public
- The relator serves the government with a confidential disclosure statement
- The government investigates during the seal period, often lasting well over a year
- The government decides whether to intervene or let the relator proceed alone
- The case resolves, usually by settlement, and the relator receives a share of the recovery
Because the dynamics are complex and the government is always a participant, experienced relator counsel is a major factor in the outcome. See how attorneys approach these matters on our FCA practice guide for attorneys.
Who Can Be a Relator — and Who Can Be a Defendant
A relator is typically an insider: an employee, former employee, contractor, or competitor with first-hand knowledge of the fraud. Citizenship is not required; credible, specific evidence is what matters.
A defendant can be almost any person or organization that submits — or causes someone else to submit — false claims for federal funds. That includes hospitals, physician groups, drug and device makers, defense and infrastructure contractors, universities, and the executives or companies that direct the conduct.
Even a party that never bills the government directly can be liable if it causes a false claim to be submitted. Eligibility rules — including the public disclosure bar and first-to-file rule — are covered on our Do I Have a Qui Tam Case? page.
How a Case Proceeds — Step by Step
Under-seal filing
The relator and attorney prepare a detailed complaint describing the fraud and file it under seal in federal court.
Government disclosure
The relator serves the government a confidential disclosure statement laying out the evidence.
Investigation
Prosecutors investigate while the case stays sealed, frequently for well over a year.
Intervention decision
The government decides whether to intervene and take over the case or decline and let the relator proceed alone.
Resolution
Most successful matters end in negotiated settlement; the relator's share is calculated from the recovery.
Time limits matter too. The Act contains statutes of limitation, and the first-to-file rule means only the first relator to bring a given fraud can usually recover. If you suspect fraud, getting advice promptly protects your position.
Why This Matters to You
If you have seen conduct that fits these patterns, the False Claims Act may give you standing to act. A working knowledge of the statute is the foundation — and that is what this page is meant to give you.
Write down what you remember: specific dates, dollar amounts, and how you learned about the conduct. Do not take records you are not entitled to, keep the matter confidential, and act before someone else files. Our confidential consultation page is the fastest way to learn your options.
Two Concepts That Decide Modern Cases
Materiality
A false statement must be material — capable of influencing the government's decision to pay. Trivial or technical violations that would not have changed the payment decision generally do not create liability. Whether the government kept paying after learning of the issue can be relevant evidence.
Public disclosure & original source
The Act prevents relators from bringing claims based purely on allegations already disclosed publicly unless the relator is an original source with independent, direct knowledge. Both terms are defined further in our legal glossary.
Federal and state false claims laws
Many states have enacted their own false claims laws covering fraud against state programs such as Medicaid. A single scheme can sometimes give rise to both federal and state claims. The False Claims Act also works alongside criminal fraud statutes, the Anti-Kickback Statute, and the Stark law — a single scheme can trigger several at once.
Frequently Asked Questions
When was the False Claims Act passed?
It was enacted in 1863 during the Civil War and substantially strengthened by amendments in 1986 and again in 2009.
Does the False Claims Act only cover healthcare fraud?
No. It covers any false claim for federal funds — defense contracting, infrastructure, grants, customs, and more — though healthcare is the largest category of recoveries.
What does "knowingly" mean under the Act?
It includes actual knowledge, deliberate ignorance of the truth, and reckless disregard. Specific intent to defraud is not required.
Can a single mistake trigger liability?
Generally no. The false statement must be material — capable of affecting the government's payment decision — and made knowingly, not by honest error.
Who can sue under the False Claims Act?
The government can, and so can private relators through the qui tam provisions, as long as they meet the law's requirements.
