IRS Whistleblower Rewards: The Money Your Information Helps Recover

A qualifying IRS whistleblower reward ordinarily pays 15% to 30% of the proceeds collected through an action your information substantially helps. If you know why a company’s tax return leaves out money its own records show, that knowledge can have value beyond the accounting department.

This page explains the financial requirements and the money an award under the IRS whistleblower program is based on. The starting point is the transaction you understand: the income omitted, the deduction inflated, the payroll tax reported but diverted. Our whistleblower experts help connect that knowledge to the tax issue and the evidence behind it.

How Much Do You Get for Reporting Someone for Tax Fraud?

The IRS whistleblower reward amount depends on the collected proceeds attributable to your information and the share awarded for your contribution. The IRS whistleblower law ties those together: information helps an enforcement action, that action produces collections, and the Whistleblower Office determines the award. Money collected through a settlement responding to the action also falls within the law.

The IRS controls the tax examination, assessment, settlement and collection. The Whistleblower Office evaluates the information and the award.

A tax assessment, a government recovery and a whistleblower award describe different amounts. An assessment records a tax liability, the recovery is money collected, and the award is the whistleblower’s share.

What Are the Requirements for an IRS Whistleblower?

An IRS whistleblower needs specific, credible information that contributes to an action producing collected proceeds. The mandatory award framework also has financial requirements concerning the amount in dispute and, for an individual taxpayer, gross income. Both tests use a strict greater-than rule.

The IRS Whistleblower Threshold Must Be Exceeded

The proceeds in dispute must exceed $2 million. Exactly that amount does not satisfy the mandatory threshold. Tax, penalties and interest can count toward the proceeds in dispute, so the financial test reaches beyond the basic unpaid tax.

That threshold concerns the tax matter being pursued. The whistleblower’s reward comes from the resulting collections, with the percentage reflecting the contribution. The amount needed to qualify for the mandatory framework and the amount used to calculate the award do different jobs.

The Individual Taxpayer’s Gross Income Matters

When the target is an individual taxpayer, that person’s gross income must exceed $200,000 in at least one tax year covered by the action. Equality does not meet this condition either. The test concerns the individual being reported, not the whistleblower’s own income.

The law applies the gross-income condition specifically to individual targets. A company target has no corresponding individual-income test. Knowing whose tax obligation the transactions affect therefore matters alongside knowing how much is in dispute.

Collected Proceeds Versus Assessed Tax

Collected proceeds are the money base for an IRS whistleblower award. Assessed tax records what the taxpayer owes. The Treasury regulation’s example uses a $2.1 million dispute with a final liability of $1.75 million. The example shows that the dispute can meet the threshold even when the final liability is smaller.

The underlying tax liability must also be final for payment of an award. The IRS can make later award determinations when additional proceeds arise, and it can address completed actions separately. For someone who knows several transactions or tax years, the useful question is how each connects to the tax action and its collections.

What Counts as Collected Proceeds?

IRS whistleblower collected proceeds can include tax, penalties, interest and additions to tax. The law also reaches proceeds from reporting violations within the IRS’s authority. That broader definition matters when an insider’s knowledge concerns an undisclosed account or a reporting failure alongside the tax return.

The Broader Definition Congress Adopted

Congress expanded the proceeds language in 2018. The older 2014 regulation’s narrower wording cannot override the statute, which reaches proceeds under laws the IRS is authorized to administer, enforce or investigate.

For an IRS whistleblower with information about foreign accounts, proceeds from violations involving the Report of Foreign Bank and Financial Accounts belong in that broader framework. The IRS’s award manual directs analysts to check related FBAR collections.

Retained Refunds Can Count Too

Collected proceeds can include a refund the government retains, as well as attributable credits applied to liabilities and payments made with amended returns. The regulation illustrates this with a $400,000 foregone refund and a $100,000 cash payment, which it treats as $500,000 in proceeds. Money the government keeps can therefore matter alongside money newly paid.

That distinction matters to an insider who knows a refund claim was inflated. The claimed refund and the amount the government actually retains serve different roles in the account. Our whistleblower experts examine the transaction and the resulting tax treatment together when assessing what your information contributes.

What Determines the IRS Whistleblower Award Percentage?

The extent of the whistleblower’s substantial contribution determines the award percentage. The award regulation recognizes the value of identifying an issue the IRS did not know about or could not readily detect, explaining connections among transactions and parties, identifying collectible assets and providing exceptional assistance. Clear information can save investigative work as well as expose an underpayment.

Contribution can include helping the IRS initiate, expand or continue an action. A federal appeals court’s 2025 opinion explained that supporting a tax adjustment already under examination can also count. A whistleblower may understand why an existing tax issue is well founded because they know the transactions behind it.

For someone inside the business, the useful connection is specific: what information helped establish which tax issue. The transactions, people responsible and records behind that issue give the contribution its substance. That is the part we work through with you when assessing the reward opportunity.

Reward laws put value on knowledge held inside a business. The 2019 working paper Do Corporate Whistleblower Laws Deter Accounting Fraud?, available through MIT Sloan, studied companies exposed to state False Claims Acts through state pension fund ownership. It found a 5% to 9% reduction in estimated accounting-fraud probability after that exposure. The study concerns the incentive for insiders to report through those state laws. An IRS award turns on what your information contributes to the tax action and its collections.

IRS Discretionary Awards Below the Mandatory Threshold

An IRS whistleblower discretionary award remains possible below the mandatory financial threshold. The law gives the IRS separate authority to pay for information that leads to collections outside the mandatory framework. The current manual applies the same contribution criteria to these newer claims while retaining discretion.

Discretionary awards for smaller tax matters have no fixed percentage or dollar cap in the statute. Historical award schedules and caps applied to older submissions. For a reader with a smaller tax matter, the central questions remain what the information contributes and what money it helps recover.

What Evidence Do I Need for an IRS Whistleblower?

Useful IRS whistleblower evidence connects the taxpayer, the transaction, the tax years and the specific underpayment or violation. It also explains how the whistleblower knows those facts and where supporting records can be found. Someone who understands the business can explain relationships among documents that look disconnected outside it.

Payroll offers a concrete example. Calculating and reporting payroll taxes is one control point; depositing the money is another. An employer’s debit to an outside payroll provider does not establish that the taxes reached the government. Authorization records, transaction histories and actual tax credits can show what happened to the money.

Offshore accounts pose a different identification problem. The account’s formal label and the person who actually owns it can tell different stories. Ownership evidence and transaction histories help connect the account to the taxpayer, while the reporting and collection records explain the tax issue. The person who understands the relationship may be able to supply the connection the account label conceals.

A Valuation Used to Sell a Tax Deduction

The Justice Department’s complaint against EcoVest alleged that appraisers used unrealistic assumptions to inflate conservation easement valuations. It described how the valuation supported the sale of interests in the businesses claiming the deductions:

If you saw the appraisal assumptions or the sales instructions, those records could explain how a marketed tax benefit reached the customer’s return. We see the absurdity in the Justice Department’s allegation: the gift’s appraisal had become the sales pitch.

The return is the endpoint of that chain. Promoters, advisers, appraisers and preparers may each hold a different part of it. Connecting their decisions to the claimed deduction is more useful than treating the return as a document that explains itself.

The Award and the Recipient’s Payment

The gross award and the recipient’s payment are separate accounting amounts. A Tax Court award opinion distinguishes the collection base, the gross award and tax withheld from the payment. Withholding concerns the payment to the whistleblower, while collected proceeds concern the money recovered through the tax action.
