Whistleblower award denied after target pays more tax on its own returns

Whistleblower 11099-13W v. Commissioner. Tax Court No. 11099-13W. Memo. 2026-5.

The Tax Court upheld a denial of a whistleblower award because the IRS did not collect any proceeds from an IRS action, and the taxes the company reported and paid on its own returns did not count as “collected proceeds” under §7623(b).

Holding

The IRS did not collect proceeds “as a result of” an administrative or judicial action based on the whistleblower’s information.

Self-reported tax paid with an original return is not “collected proceeds.” The Whistleblower Office did not abuse its discretion in denying the award.

Why It Matters

• Whistleblower awards under §7623(b) require IRS action and collected proceeds tied to that action, not just taxpayer behavior changes.

• A taxpayer’s voluntary compliance shift, including an accounting method change, does not create award-eligible proceeds if the IRS did not collect them through an enforcement action.

• The case reinforces Lewis. Reported and paid tax does not count as collected proceeds, even when a taxpayer changes reporting while an examination is ongoing.

• Record fights often become irrelevant when the dispute turns on a legal rule that disposes of the case.

Timeline

• June to July 2008: Whistleblower files Form 211 alleging LIFO-related inventory manipulation that inflated the cost of goods sold.

• 2008 to 2010: IRS teams review the claim during examinations of the target’s 2006 to 2009 cycles. The IRS cannot substantiate the allegations.

• February 2010: Whistleblower asserts the target stopped the alleged conduct in 2009 and argues the resulting higher reported tax should count for an award.

• March 2012: Target files Form 3115 to change inventory accounting from LIFO to FIFO effective for 2011.

• April 2013: Whistleblower Office denies the award. Whistleblower petitions the Tax Court.

• January 13, 2026: Tax Court grants IRS summary judgment and denies remaining motions.

Key Facts

• The whistleblower alleged that the target used “coupled” year-end inventory trades to exploit LIFO, a last-in, first-out inventory accounting method.

• IRS exam teams investigated during multiple audit cycles and concluded they could not substantiate the claimed scheme.

• The target later changed the inventory accounting from LIFO to FIFO, which is first-in, first-out.

• The whistleblower sought an award based on additional tax the target allegedly paid after it stopped the alleged trading behavior and moved from LIFO to FIFO.

Statutory or Regulatory Framework

• §7623(b)(1) provides a mandatory award only if the IRS proceeds with an administrative or judicial action based on the whistleblower’s information and collects proceeds as a result of that action.

• The Tax Court reviews Whistleblower Office award determinations under an abuse-of-discretion standard using Administrative Procedure Act principles.

• The Court generally confines review to the administrative record designated by the agency.

Arguments

Taxpayer (whistleblower) argued:

• The target changed his behavior and paid more tax because the IRS investigated based on his information.

• “Collected proceeds” should include any additional tax the target reported and paid after the alleged scheme ended and the accounting method change.

• The Whistleblower Office relied on incomplete or deficient forms and did not fully understand the basis for the award claim.

• The Court should expand or supplement the administrative record to include broader IRS examination materials.

Government argued:

• The IRS could not substantiate the alleged noncompliance and made no audit adjustments tied to the whistleblower’s claim.

• No “collected proceeds” existed because the IRS did not collect anything from an action based on the whistleblower’s information.

• Self-assessed tax reported and paid on original returns is not “collected proceeds” for §7623(b)(1).

• A voluntary Form 3115 accounting method change is taxpayer-initiated and does not create award-eligible proceeds absent IRS collection from an enforcement action.

Court’s Reasoning

• The Court treated the Whistleblower Office claim file as the administrative record for review.

• The Court applied abuse-of-discretion review and asked whether the denial was arbitrary, capricious, or contrary to law.

• The whistleblower’s core theory depended on treating increased tax shown on the target’s own returns as award-eligible proceeds.

• The Court followed Lewis v. Commissioner and held that “reported, paid tax is not collected proceeds.”

• The timing point did not save the claim. Even if the accounting method change occurred while an examination was still underway, the rule still excludes self-reported tax from collected proceeds.

• Because the dispositive issue was legal, the Court denied record-scope and supplementation motions as irrelevant to the outcome.

• The Court denied trial-related evidentiary motions as moot after granting summary judgment.

Forward-Looking Implications

• Whistleblowers cannot base award claims on a target’s voluntary “clean up” on future original returns, even if IRS scrutiny arguably influenced the change.

• Accounting method changes, including LIFO-to-FIFO conversions, will not support an award unless proceeds are collected through an IRS action tied to the whistleblower submission.

• If a whistleblower wants to maximize award viability, the record needs a clear link between the submission, an IRS action, and proceeds collected through that action.

• Procedural fights over the administrative record will not matter when binding precedent forecloses the theory of proceeds.

Result

The Tax Court granted the IRS's motion for summary judgment and upheld the denial of the whistleblower award. It denied the remaining motions.

The Takeaway

This case kills the common fantasy that “they paid more tax, so pay me.” §7623(b) pays on proceeds the IRS collects through IRS action. It does not pay taxes on behalf of a taxpayer; the taxpayer reports and pays them on its own.
