IRS Whistleblower Substantial Contribution: An IRS Tip Can Open an Audit and Earn Nothing

An IRS whistleblower makes a substantial contribution when the information materially helps the IRS pursue the tax issue that produces a recovery. Opening an audit alone does not establish that connection. If you know which transactions disappeared from a return, or why the company’s explanation leaves out part of the deal, the value lies in what those facts let the IRS establish. This page follows that connection from the information to the adjustment and the money collected.

An audit already underway can still benefit from an insider’s information. The court decisions also require the IRS to support its account of what the information contributed. We examine both sides with you: what your evidence adds and what the agency says it used.

The IRS Award Follows the Money Collected

A qualifying IRS whistleblower award pays a share of collected proceeds attributable to the information. The federal tax whistleblower law ties the award to money collected through the action or a settlement responding to it. The amount of tax alleged, the size of a disputed deduction and the government’s recovery are different numbers.

The mandatory award program applies when proceeds in dispute exceed $2 million. For an individual taxpayer, gross income must also exceed $200,000 in at least one relevant tax year. A separate discretionary program covers other qualifying information.

A whistleblower case under the False Claims Act can pay 15% to 30% of what the government recovers. Federal tax claims follow a separate route: the federal False Claims Act excludes claims under the Internal Revenue Code, and federal tax whistleblowers pursue an award through the IRS. The IRS decides whether to examine the taxpayer, pursue an adjustment and collect the money. Our work starts with the specific underpayment your information can help establish.

What If IRS Whistleblower Information Leads to a Different Tax Adjustment?

When IRS whistleblower information leads to a different tax adjustment, the award depends on what the information contributed to that adjustment. An unrelated issue does not become awardable merely because it surfaced in the same audit. A January 2025 D.C. Circuit decision makes the distinction concrete.

The whistleblower reported a condominium development group’s treatment of golf-club membership deposits. The submission said that deposits made nonrefundable should have been reported as gross income. The IRS had not planned to investigate the development group, and the information prompted an examination. The revenue agent then examined the deposit issue and accepted the group’s tax treatment.

During that examination, the agent independently found a different problem: an improper $60 million bad-debt deduction. The agent expanded the examination using facts he had discovered and reported that the whistleblower had supplied no information about the adjusted issues.

The court agreed that the unrelated adjustment did not earn the whistleblower an award. It accepted that the IRS could treat distinct tax issues within an examination separately when deciding what the whistleblower’s information produced. We see the disconnect plainly: the tip got the IRS through the door, but the paying issue came from a different investigation inside it.

An IRS whistleblower’s substantial contribution to one issue does not extend to an unrelated issue merely because the taxpayer is the same. If you know how the deposit records, debt records or transactions connect, that connection is what we examine with you. The case turns on the information’s relationship to the adjusted issue, not the fact that everything sits in one taxpayer’s file.

Can Additional Information Matter When the Taxpayer Is Already Under Audit?

An IRS whistleblower can make a substantial contribution through additional information when the taxpayer is already under audit. Information can start an action, expand its scope or help the IRS continue pursuing it. It can also help prove or settle an issue the IRS already knows about.

Evidence that helps prove or settle a known issue can contribute to the recovery, as an August 2025 D.C. Circuit decision recognized. The court required the Whistleblower Office to consider relevant material missing from its account of the contribution. Identifying a previously unknown taxpayer or transaction was not the only way information could matter.

That distinction speaks directly to an insider who knows the explanation behind a transaction already under examination. The IRS may know an issue exists while still needing evidence that helps prove it or resolve it. We look at the particular fact your account adds, the documents behind it and the adjustment it supports. The opening date of the audit does not answer those questions.

What Counts as a Related IRS Action?

A related IRS action requires a specific connection to the whistleblower’s information. It concerns another taxpayer, substantially the same underlying facts and an action based on the specific facts the whistleblower supplied. The information must let the IRS identify that additional taxpayer without first finding someone else or independently obtaining more information.

The offshore-disclosure award decision shows why that connection matters. A whistleblower who cooperated in a criminal investigation involving Swiss bankers and undisclosed offshore accounts received more than $8.5 million in awards. The whistleblower then sought an additional award connected to more than $2.3 billion collected through the IRS Offshore Voluntary Disclosure Initiative.

The court left the dismissal of that additional claim in place. The voluntary disclosures and payments at issue did not establish that the IRS had taken a qualifying action against those taxpayers based on his information. The earlier awards did not establish the required connection to the initiative’s wider collections.

The court also recognized that a voluntary disclosure could lead to an actual IRS examination that might support an award. The practical question remains which action the information helped produce. When your knowledge reaches several participants in a transaction, we examine those connections individually rather than treating the size of the wider recovery as the answer.

What If an IRS Whistleblower Claim Is Forwarded but There Is No Examination?

When an IRS whistleblower claim is forwarded but there is no examination, internal processing has not become an audit of the taxpayer. The D.C. Circuit’s July 2025 decision on two whistleblowers’ claims separated that internal processing from an actual audit. Moving the information to an operating division did not establish that the IRS acted against the taxpayer.

In one claim, the operating division reviewed the submission and made a preliminary review of the return before deciding not to investigate further. The court treated that review as preparation for deciding whether to examine the taxpayer, rather than the examination itself. A referral and an audit described different events.

Another claim did produce an audit. The examination made no change to the return and produced no collected proceeds to support an award. Receipt, referral, examination and collection each answered a different question. We read the IRS’s letters against what it actually did with your information.

What If the IRS Says It Already Knew?

The IRS’s general knowledge of an audit subject does not establish that it already knew the particular issue the whistleblower supplied. A September 2025 award-percentage decision required closer attention to that difference. The agency needed support for its claim that the examination team had discovered the particular issue independently.

The Whistleblower Office had awarded a lower percentage on one recovery than on the other recoveries in the matter. The court found that the IRS lacked support for its claim of independent knowledge. Knowing the audit subject was not the same as already knowing the issue that produced the recovery.

For someone who supplied information about an existing issue, the details of that exchange can be consequential. What the IRS knew before the submission, what reached the examiners and what the information helped them establish are separate facts. We work through those distinctions with you when the agency’s explanation does not match the contribution you made.

What If the IRS Ignores Part of Your Submission?

Information in an application or cover letter can matter even when the IRS excludes its attachments. In a 2026 decision, reissued that July, the whistleblower’s application and cover letter reached the examination team despite the excluded attachments. The team considered their substance. Excluding the attachments did not establish that the rest of the submission had never contributed.

The agency had documented its reasoning for earlier tax years but had not adequately explained its decision for the later years. Similar conduct in later tax years can support an award when the IRS investigates and collects based on the information. We see the problem in treating an entire submission as unused when the examiners considered part of it. The file and the explanation have to agree.

What Makes a Case Actionable?

Specific information connecting a taxpayer, transactions and tax years to an identifiable underpayment makes a tax report useful for examination. For an IRS award, the inquiry goes further: what did that information help the agency establish and recover? We connect the account you give us to the particular records and tax issue it explains.

The business detail matters. In the membership-deposit case, the reported issue concerned when the business should recognize income. The adjustment concerned a debt it treated as worthless. Both affected the same group’s return, but they called for evidence about different transactions. Knowing the business can help explain a connection that the return alone does not show.

A 2014 Villanova Law Review paper, Clash for Cash: The Conflict Over Tax Whistleblower Contracts, examined a practical obstacle to using that knowledge. It described examiners’ questions passing through an intermediary and the whistleblower’s answers being relayed back. It described practitioners’ concern that those exchanges could limit what an examiner learned compared with direct interaction. We see the practical problem: what an insider knows and what the examiner hears are not always the same thing.

An organized explanation also has a place in the IRS award factors. Those factors recognize information about difficult-to-detect issues, assistance that saves IRS resources, collectible assets and connections between transactions or participants. The volume of documents alone does not explain what they contributed. We focus on the records that show why the tax treatment was wrong and how your information helped the IRS establish it.
