Background
Mary Trongone filed a Form 211 whistleblower application with the IRS in October 2012, alleging that two taxpayers had violated the tax laws during 2004–2012. She also requested that the IRS consider similar conduct in tax years 2013–2017 when issuing any award. Trongone’s application included nineteen pages of supporting documents, some of which were internal to one of the target taxpayers. Although Trongone had never worked there, the IRS subject-matter expert (SME) flagged these documents as potentially “tainted”—obtained unlawfully or subject to a valid privilege claim—and returned them to the IRS Whistleblower Office (WBO). However, the SME forwarded Trongone’s Form 211 and cover letter to the exam team.
The IRS ultimately denied Trongone’s whistleblower award claim. For tax years 2011–2012, the agency produced extensive documentation (nearly 900 pages) showing it had already known the facts underlying her allegations and that her application had not contributed to the audits. For tax years 2013–2017, however, the WBO analyst simply asserted that because Trongone’s application was tainted, the exam team would not have relied on it. The Tax Court granted summary judgment for the IRS without supplementing the administrative record. Trongone appealed, and the D.C. Circuit appointed a law professor as amicus curiae to present her arguments.
The Court’s Holding
The D.C. Circuit reversed, holding that the IRS’s decision regarding tax years 2013–2017 was arbitrary and capricious because it was not supported by the administrative record. Although the IRS had provided detailed, well-documented analysis for 2011–2012, it offered only a bare assertion for 2013–2017—namely, that the application was tainted and therefore could not have aided the investigation. This reasoning ran counter to the existing record, which showed that the SME had forwarded the non-tainted portions of Trongone’s application (the Form 211 and cover letter) to the exam team for 2011–2012.
The court identified a critical logical gap: if the exam team considered Trongone’s application for 2011–2012, why would it not have done so for 2013–2017? The record was largely silent on this question. Moreover, the SME’s taint determination applied to the attached documents, not to the Form 211 and cover letter themselves. The court concluded that the IRS should have conducted a reasonable inquiry into whether Trongone’s application contributed to the investigation of 2013–2017 before denying her claim. Instead, it relied on an unsupported rationale that contradicted what the record actually showed about how the exam team handled the application.
Key Takeaways
- IRS whistleblower award denials must be supported by adequate reasoning and documentation; mere assertions are insufficient and subject to reversal under the Administrative Procedure Act.
- An agency’s rationale for denying a claim will be rejected if it “runs counter to” or is contradicted by evidence in the administrative record.
- Where an IRS administrative record is silent or perfunctory regarding specific tax years at issue, summary judgment is inappropriate; remand for further agency investigation is the correct remedy.
- Taint determinations must be carefully applied and cannot serve as a blanket reason to ignore a whistleblower’s allegations without analyzing the non-tainted portions of the application.
Why It Matters
This decision reinforces meaningful judicial review of IRS whistleblower award decisions and establishes that the agency cannot rely on conclusory statements or logical gaps to deny claims. The court’s emphasis on comparing the IRS’s detailed analysis for 2011–2012 against its perfunctory treatment of 2013–2017 sets a clear standard: once an agency begins investigating conduct related to a whistleblower’s allegations, it must carefully document why the whistleblower’s information did not contribute to subsequent investigations of similar conduct. For whistleblower practitioners, the decision demonstrates that summary judgment is inappropriate when the administrative record fails to support the agency’s stated rationale or is inadequate on key issues.
On remand, the IRS retains the authority to deny Trongone’s claim—but only after providing a reasoned explanation supported by the record. The decision thus protects whistleblowers from arbitrary agency action while preserving the IRS’s ultimate discretion to weigh whether an application actually contributed to collection activities. This balance reflects the court’s view that mandatory whistleblower awards under the 2006 statutory framework require more rigorous agency analysis than was previously customary.
