IRS Whistleblower Award Denied Because the IRS Already Had the Information? What You Must Show

If the IRS Whistleblower Office says it already had the issue and your information did not substantially contribute, you get a mandatory award only by showing that the IRS action was based on your information: that it started, expanded or kept pursuing the case because of something you supplied. Reporting first is not enough, and the Tax Court will judge the denial on the administrative record, so the time to prove what your information added is your response to the preliminary denial letter.

In Bialer v. Commissioner, T.C. Memo. 2026-110, the IRS collected tax from a bank, but the audit team worked from a Senate subcommittee report and another whistleblower’s records, and the Tax Court sustained the denial of his award.

What substantially contributed means

Under 26 U.S.C. § 7623(b)(1), a mandatory award of 15 to 30 percent of collected proceeds depends on the IRS proceeding with an action based on information you brought to its attention. These rules apply only when the proceeds in dispute exceed $2,000,000 and, if the taxpayer is an individual, gross income exceeds $200,000 in a year subject to the action (section 7623(b)(5)). Smaller claims are considered for a discretionary award under section 7623(a), without the comment procedure described below. The regulation, 26 C.F.R. § 301.7623-2(b), says the IRS proceeds based on your information when “the information provided substantially contributes to an action against a person identified by the whistleblower.”

The regulation gives three examples: the IRS starts a new action, expands an ongoing one, or continues one that it would not have started, expanded or continued but for your information. It also draws a line: “The IRS does not proceed based on information when the IRS analyzes the information provided or investigates a matter raised by the information provided.”

When the IRS is already auditing, the examples draw the line this way:

• Counts: your documents lead the IRS to examine sales in another country or to make an adjustment it would not have made from its own information. Only that added portion is based on your information.
• Does not count: the audit team uses your documents only to confirm adjustments it was already making. The regulation calls that information that “merely supports information independently obtained by the IRS.”

Being first is not the test

In Bialer, the court said the statute requires action based on the whistleblower’s information, “not that he be the first to report.” Mr. Bialer filed in 2007, but his claim reached the audit team only in January 2010, after the team had held the Senate report and the other whistleblower’s records for more than a year; the withholding audit it opened that November was built on them.

Timing still matters as evidence of when your information reached the examiners and what they did with it. Your job is to identify a fact, document, transaction or year in your submission that the IRS did not already have and that changed the case.

When a report or news story came first

Under section 7623(b)(2), if the Whistleblower Office finds the action was based principally on specific allegations disclosed in a hearing, a government report, audit or investigation, or the news media, it may award up to 10 percent. That cap does not apply if you were the original source of the information that started the action.

Bialer shows the evidence problem. Mr. Bialer argued that his claim must have prompted the Senate investigation; the court found that theory not tenable because the other whistleblower had supplied the subcommittee and Mr. Bialer claimed no contact with it. If you believe you were the source behind a report or article, you need evidence of that chain, not an inference from timing.

Use the 30-day response to build the record

If the IRS did not proceed based on your information, you will get a preliminary denial letter. Under 26 C.F.R. § 301.7623-3(c)(8), you have 30 days from the date it is sent to submit comments, a period the office may extend at its discretion. Your comments go into the claim file from which the Tax Court record is drawn.

In our view, a useful response:

• Quotes the denial’s stated reason and answers that reason.
• Points to the exact page of your Form 211 or later submission that contains the information you say the IRS used.
• Explains why that information was new to the IRS and which adjustment, year or taxpayer it affected.

In Bialer, the court said arguments raised later “should have been elaborated and substantiated in Mr. Bialer’s response to the preliminary denial letter, but they were not.” The regulations also warn that if you leave information out, you bear “the risk that this information might not be considered” for an award, under 26 C.F.R. § 301.7623-1(c)(1).

When adding documents in Tax Court fails

You may petition the Tax Court within 30 days of the final determination, but the court reviews the administrative record for abuse of discretion and allows supplementation only in limited cases, such as documents that were before the agency but left out, or a serious question about the agency’s process.

In Bialer, the court added documents from Mr. Bialer’s pre-filing presentation and an IRS interview of him, but it kept out internal IRS emails, spreadsheets and case-tracking entries as immaterial: at most they showed an audit team’s decision not to use his information, and only the Whistleblower Office’s determination is reviewable.

Our Bialer case analysis covers the court’s full reasoning. If the denial instead says the IRS collected nothing, our guide to collected proceeds addresses that separate question.
