Tax Court Lacks Jurisdiction Over Whistleblower Claim Denied After IRS Classifier Review

Whistleblower’s $10K Claim Dismissed: Tax Court Rules Jurisdiction Absent IRS Action

The stakes couldn’t have been higher for William Pratt—or for the future of whistleblower claims before the U.S. Tax Court. Pratt’s $10,000 dispute wasn’t just about the money; it was a jurisdictional showdown testing whether the Tax Court could assert authority over the IRS when no administrative or judicial action had been taken against the target taxpayer. In a decisive ruling that reinforces the boundaries of its jurisdiction under Section 7623(b)(4), the Tax Court dismissed Pratt’s whistleblower petition for lack of jurisdiction, citing the D.C. Circuit’s recent decision in Kennedy v. Commissioner. The message was clear: the Tax Court will not entertain whistleblower claims unless the IRS has issued a final determination—meaning the agency must have either initiated an examination or pursued judicial action based on the whistleblower’s information. For Pratt, the ruling was a dead end. For whistleblowers nationwide, it was a warning: the court’s doors swing open only when the IRS acts.

The Whistleblower’s Story: A $10K Claim and the IRS’s Silent Rejection

On July 3, 2021, William Pratt submitted Form 211, Application for Award for Original Information, to the IRS Whistleblower Office (WBO). Pratt alleged that a target taxpayer had violated internal revenue laws by failing to file tax returns reporting income for multiple taxable years. To substantiate his claim, he attached legal documents identifying the target taxpayer and noted the absence of the IRS as a named creditor in the taxpayer’s filings.

The WBO acknowledged receipt of Pratt’s Form 211 on August 23, 2021, assigning it claim number 2021-013917. The claim was then routed to a classifier within the IRS’s Small Business/Self-Employed (SB/SE) Operating Division. On September 13, 2021, the classifier issued a recommendation to deny the claim, citing that while Pratt’s allegations met the criteria under Section 7623(a)—which governs discretionary whistleblower awards—the alleged amount in dispute was under $10,000. Under Section 7623(b)(1), which mandates awards for whistleblowers who provide information leading to the collection of proceeds in excess of $2 million (or $200,000 for individuals with gross income exceeding $200,000), the classifier determined that Pratt’s claim did not qualify for further review.

The WBO adopted the classifier’s recommendation and issued Pratt a final determination letter on September 20, 2021. The letter stated that the information provided did not result in the collection of any proceeds, rendering Pratt ineligible for an award. Crucially, the IRS took no administrative or judicial action against the target taxpayer based on Pratt’s allegations. The WBO did not refer the claim to an examination team, nor did it initiate any enforcement activity.

Undeterred, Pratt filed a timely petition with the Tax Court on October 20, 2021, seeking review of the IRS’s denial. The petition reiterated the allegations made in Form 211 and included the same supporting documents. The IRS responded by filing an Answer on December 16, 2021, setting the stage for a jurisdictional showdown that would hinge on whether the IRS’s inaction against the target taxpayer barred Tax Court review.

Jurisdictional Battle: Pratt’s Argument vs. the IRS’s Kennedy Precedent

Undeterred, Pratt filed a timely petition with the Tax Court on October 20, 2021, seeking review of the IRS’s denial. The petition reiterated the allegations made in Form 211 and included the same supporting documents. The IRS responded by filing an Answer on December 16, 2021, setting the stage for a jurisdictional showdown that would hinge on whether the IRS’s inaction against the target taxpayer barred Tax Court review.

Pratt’s argument hinged on a narrow reading of Section 7623(b)(4), which grants the Tax Court jurisdiction over "any determination regarding an award under paragraph (1), (2), or (3)." He contended that the Whistleblower Office’s (WBO) transmission of his claim to the Small Business/Self-Employed (SB/SE) operating division constituted an administrative action sufficient to trigger Tax Court jurisdiction. Pratt emphasized that the classifier’s recommendation—though ultimately leading to denial—represented a procedural step beyond mere inaction, arguing that the IRS had "proceeded with" administrative review by assigning the claim to a specialized unit for evaluation.

The IRS countered by invoking Kennedy v. Commissioner, 142 F.4th 769 (D.C. Cir. 2025), a recent appellate precedent that sharply limited the Tax Court’s jurisdiction in whistleblower cases. The agency argued that the classifier’s review was a preliminary step, not an administrative or judicial action under Section 7623(b)(1). The IRS stressed that Section 7623(b)(4) requires a "determination" by the Secretary—defined as proceeding with an administrative or judicial action based on the whistleblower’s information. Here, the classifier’s role, as outlined in Internal Revenue Manual 25.2.1.3.1, was merely to assess whether the claim merited further review, not to initiate any enforcement activity against the target taxpayer. The IRS further distinguished Lissack v. Commissioner, 125 F.4th 245 (D.C. Cir. 2025), which held that jurisdiction exists when the IRS proceeds with an administrative action, noting that Pratt’s claim never advanced beyond classification. The agency framed the classifier’s role as analogous to a gatekeeper, not an actor that "proceeds" against a taxpayer under the statute.

The Court’s Hands Are Tied: How Kennedy Narrowed Whistleblower Jurisdiction

The Tax Court’s dismissal of William Pratt’s whistleblower petition hinged on a single, unassailable principle: jurisdiction under Section 7623(b)(4) does not exist unless the IRS issues a final determination that the whistleblower’s claim has merit. In Pratt’s case, the IRS never crossed that threshold—despite forwarding his claim to an operating division for review. The court’s hands were tied by the D.C. Circuit’s recent decision in Kennedy v. Commissioner, which drew a bright line between preliminary agency actions and the kind of administrative or judicial proceeding that triggers Tax Court jurisdiction.

Section 7623(b)(4) grants the Tax Court jurisdiction over whistleblower award determinations, but only when the IRS has taken a concrete step against the target taxpayer. The statute requires that the Secretary of the Treasury “proceeds with any administrative or judicial action” based on the whistleblower’s information. This language is not aspirational—it is jurisdictional. The court emphasized that Congress did not vest the Tax Court with general oversight of the IRS Whistleblower Office’s internal processes. Instead, the Tax Court’s authority is cabined by the IRS’s decision to initiate an enforcement action, such as an examination, audit, or litigation. Without that action, the court lacks the power to review the IRS’s handling of the claim.

The IRS’s classifier system, as outlined in Internal Revenue Manual 25.2.1.3.1, plays a critical but limited role in this framework. Classifiers evaluate whether a whistleblower’s claim meets the statutory thresholds and whether the allegations are specific and credible enough to warrant further review. Their role is analogous to a gatekeeper—not an actor that “proceeds” against a taxpayer. In Pratt’s case, the classifier in the Small Business/Self-Employed division recommended denying his claim because the alleged amount in dispute was under $10,000. The Whistleblower Office adopted this recommendation and issued a final denial letter, but the court found this action insufficient to confer jurisdiction. The classifier’s recommendation was a preliminary assessment, not an administrative or judicial proceeding against the target taxpayer.

This distinction was the linchpin of the Kennedy decision, which the Tax Court cited as controlling. In Kennedy, the D.C. Circuit held that the mere transfer of a whistleblower claim to an IRS operating division for review does not constitute an administrative or judicial action under Section 7623(b)(1). The court reasoned that the Whistleblower Office’s decision to forward a claim to another division is a procedural step, not a substantive enforcement action. Similarly, the classifier’s review in Pratt’s case was a preliminary screening, not a proceeding that advanced the IRS’s investigation. The court rejected Pratt’s argument that the classifier’s involvement transformed the IRS’s inaction into a reviewable determination, noting that the classifier’s role was limited to assessing whether the claim merited further review—not to initiating any enforcement activity.

The court also distinguished Li v. Commissioner, where the D.C. Circuit held that threshold rejections (e.g., claims rejected for vagueness or lack of specificity) are not reviewable. Pratt’s case fell into a gray area between a threshold rejection and a final determination. While his claim was not rejected outright at intake, it was denied after a classifier’s review without ever advancing to an IRS examination or other enforcement action. The court found that this intermediate step did not satisfy the jurisdictional requirements of Section 7623(b)(4). The IRS’s decision to deny the claim based on the classifier’s recommendation was not a determination that the IRS had “proceeded” against the target taxpayer; it was merely the culmination of an internal review process.

The court’s reliance on Kennedy underscored its deference to the D.C. Circuit’s narrowing of Tax Court jurisdiction in whistleblower cases. By holding that the classifier’s recommendation and the Whistleblower Office’s denial did not constitute an administrative or judicial action, the court reinforced the principle that the Tax Court’s jurisdiction is strictly limited to final determinations where the IRS has taken concrete steps to address the whistleblower’s allegations. This interpretation aligns with the statutory text and the D.C. Circuit’s recent precedents, leaving whistleblowers with little recourse when the IRS declines to pursue their claims beyond preliminary review.

A Chilling Precedent: What Pratt’s Dismissal Means for Future Whistleblowers

The Tax Court’s dismissal of Pratt’s whistleblower petition did not merely close the door on a single claim—it slammed shut a critical pathway for whistleblowers with smaller or less precisely framed allegations. The ruling underscores a harsh reality: claims denied after classifier review—even if forwarded to an IRS operating division—may never clear the jurisdictional hurdle required for Tax Court review. This interpretation of Section 7623(b)(4), which governs the Tax Court’s jurisdiction over whistleblower awards, leaves whistleblowers with little recourse when the IRS declines to pursue their claims beyond preliminary scrutiny.

The court’s hands are tied by the statute’s plain text and the D.C. Circuit’s precedents, particularly Kennedy v. Commissioner, which established that the Tax Court’s jurisdiction hinges on a final determination by the IRS. A threshold rejection, no matter how erroneous or opaque, does not qualify. This means whistleblowers who receive a classifier’s rejection—even one that is later forwarded to an operating division—are effectively barred from judicial review unless the IRS issues a formal determination. The practical effect is a chilling one: whistleblowers with claims below the $2 million threshold or lacking granular specificity may abandon their efforts entirely, fearing that the IRS’s silent rejection leaves them without a forum to challenge the decision.

The implications extend beyond Pratt’s $10,000 claim. The IRS Whistleblower Office’s classifier system, governed by IRM 25.2.1.3.1, operates as a gatekeeper, wielding significant discretion to reject claims at intake. Classifiers, though not empowered to issue final determinations, effectively control the fate of whistleblowers by determining whether a claim is "specific and credible" enough to proceed. If a classifier deems a claim insufficient, the whistleblower’s only recourse is to resubmit with additional evidence—a process that offers no guarantee of success and no judicial oversight. The Tax Court’s refusal to expand its jurisdiction in Pratt’s case reinforces this power imbalance, leaving whistleblowers with no meaningful way to contest a classifier’s decision.

For future taxpayers considering blowing the whistle, the message is clear: the path to judicial review is narrow and fraught with procedural pitfalls. The IRS’s internal classifier review is not a mere formality—it is a jurisdictional gatekeeper, and its rejections are final unless the whistleblower can secure a formal determination from the IRS. This dynamic risks discouraging whistleblowers with legitimate but less polished claims, particularly those alleging smaller tax underpayments or less documentable violations. The Tax Court’s hands are tied by statute, and until Congress or the D.C. Circuit intervenes, whistleblowers will remain at the mercy of the IRS’s internal processes.
