Bialer: No Whistleblower Award When the IRS Audit Ran on a Senate Report and an Earlier Tip

A whistleblower who reports a tax scheme first can still lose the award if the IRS built its case from someone else’s information. In Bialer v. Commissioner, T.C. Memo. 2026-110, the Tax Court sustained the IRS Whistleblower Office’s denial because the record showed the audit team pursued a bank’s dividend-withholding tax using a 2008 Senate subcommittee report and another whistleblower’s documents, not Arthur Bialer’s claim. Judge Gustafson denied Mr. Bialer’s three motions to add documents to the administrative record and granted the IRS summary judgment.

The opinion was filed October 29, 2026, and the order and decision entered October 30; this analysis follows the corrected opinion served November 4.

Two whistleblowers, one Senate report and one audit

The court took these facts from the administrative record. In June 2005 an unrelated whistleblower, called WB1, told the IRS about offshore entities using equity swaps and stock loans to avoid U.S. withholding tax on dividends, and filed a Form 211 award claim in July 2005. In October 2007 WB1 met with the Senate Permanent Subcommittee on Investigations and gave it documents. Mr. Bialer does not claim any contact with the subcommittee.

In May 2007, while an earlier claim about his former employer’s total return swaps was still being processed (it produced an award in 2015), Mr. Bialer gave the Whistleblower Office a presentation that also mentioned a new bank, called Target. On September 5, 2007, he filed the Form 211 at issue, Claim T. Its support consisted mainly of term sheets for Target swaps from 1997 and 1999, his 2006 job-interview schedule with Target and correspondence.

The Whistleblower Office sent Claim T to a subject-matter expert in October 2007, but the expert did not forward it to an audit team until January 2010. Meanwhile, the subcommittee’s September 2008 report described dividend-tax abuse at six financial institutions, including Target. In December 2008 the IRS sent that report and WB1’s taxpayer-specific records to the field team. The team opened Target’s 2005 withholding return in November 2010; Target agreed to the deficiency and paid it with interest.

The team’s December 2013 evaluation said Mr. Bialer’s information was “already under consideration and provided no additional value.” It called the claim “poorly developed, lacks specifics,” noted that the detailed trades were from closed years and said the information had not been used. The Whistleblower Office’s April 5, 2019 final determination denied the award because “the IRS identified the issue(s) prior to receipt/review of your information and your information did not substantially contribute to the actions taken by the IRS.”

The question: was the IRS action based on his information?

A mandatory award under 26 U.S.C. § 7623(b) requires that the IRS proceed with an action based on the whistleblower’s information and collect proceeds as a result. The IRS undisputedly took action against Target and collected tax; the dispute was whether that action was based on Mr. Bialer’s information, which the court treated as a merits question rather than a jurisdictional one.

The court reviewed the Whistleblower Office’s determination for abuse of discretion, limited to the administrative record. It declined Mr. Bialer’s request to overrule Kasper v. Commissioner, 150 T.C. 8 (2018). With no trial in a record-review case, summary judgment decides whether the record supports the decision.

An audit team’s choice is not the award decision

Mr. Bialer’s main argument was that the real denial came years earlier, when the examining unit decided not to pursue his claim. He pointed to an undated spreadsheet entry obtained in discovery, saying his other submissions were speculative and would not be pursued, and argued it was made by June 2008 without notice to him.

The court rejected the premise. The 2006 statute that created the Whistleblower Office lets it assign a matter to another IRS office to investigate, but section 7623(b) and the regulations give the award determination to the Whistleblower Office alone. In the court’s words, “Under the law, Financial Services had no power or occasion to deny Mr. Bialer’s whistleblower award claim.” At most, the spreadsheet entry showed a decision not to use his information in an audit, and the court does not review audit decisions. On the record, the team’s no-use decision fell between January 2010 and December 2013, not June 2008.

The same reasoning disposed of the three motions to supplement, which sought IRS emails, spreadsheets and case-tracking entries. Whether the documents were treated as wrongly omitted or as extra-record evidence, “neither contention would carry the day since the information is immaterial”: they bore on an audit decision, not on the validity of the Whistleblower Office’s 2019 determination. It had earlier added documents from his pre-filing presentation and an IRS interview, and it declined to remand, holding the determination was supported “with or without the supplementation we have allowed.”

Being first was not the test

Mr. Bialer’s second argument was that he brought the Target abuses to the IRS before anyone else. In his response to the preliminary denial, he had suggested the IRS passed his claim to the Senate subcommittee, whose investigation began the month he filed. The court found that speculation unfounded given WB1’s earlier timeline: “His supposition that the IRS might have passed Claim T to the PSI is not tenable.”

His eight-page opposition to summary judgment did not cite the administrative record or deal with the Senate report. He had already admitted that the report disclosed the stock-borrowing abuse he called his best-documented issue, so the audit team learned of it in December 2008, before it ever saw Claim T. As for the foreign-tax-credit abuse he said the report missed, the court wrote: “If we look further to find FwTC in Claim T, we reach a dead end.” The closest reference, in his pre-filing chart, concerned his former employer, not Target.

Finally, the statute asks for action based on the whistleblower’s information, “not that he be the first to report.” The unchallenged fact was that the audit team acted on the Senate report and WB1’s records. “It was the PSI Report and WB1, and not Mr. Bialer, that constituted the audit team’s source of useful information.”

Result, status and what the case means

The court denied the motions to supplement and granted the Commissioner’s motion for summary judgment, sustaining the denial of Claim T.

Our reading: Bialer is about the source of the IRS’s case, not the order of the tips. A whistleblower facing a denial based on earlier information has to show, from the Form 211 and the record, a specific fact the IRS lacked and used. Discovery documents showing only what an audit team did with the tip did not help here. The response to the preliminary denial letter is the time to make that showing. Our Scott analysis covers a different gap: an audit that collected no proceeds.
