The U.S. Tax Court’s decision in Aiello v. Commissioner, T.C. Memo. 2025-46, delivered on May 15, 2025, provides important guidance on the strict application of filing deadlines in Collection Due Process (CDP) cases—even after the Supreme Court’s landmark Boechler decision opened the door to equitable tolling. The ruling underscores the high bar taxpayers must clear to excuse a late petition and reinforces the importance of timely action when challenging IRS collection determinations.
The CDP Framework
Under Internal Revenue Code § 6330, taxpayers are entitled to a CDP hearing before the IRS can proceed with certain collection actions, such as levies. If dissatisfied with the IRS’s determination, taxpayers have 30 days from the date of the notice of determination to file a petition with the Tax Court for review. Missing this deadline can be fatal to a taxpayer’s case—unless the court finds grounds for equitable tolling.
The Aiello Case
Virgil Joseph Aiello received a notice of determination following a CDP hearing. He filed his petition with the Tax Court after the 30-day statutory deadline had expired. Aiello argued that the court should excuse his late filing under the doctrine of equitable tolling, which allows courts to consider late petitions in rare circumstances where fairness demands it.
Boechler and Equitable Tolling
The Supreme Court’s 2022 decision in Boechler, P.C. v. Commissioner clarified that the 30-day deadline for filing a CDP petition is not jurisdictional and may, in theory, be subject to equitable tolling. However, the Court also emphasized that equitable tolling is reserved for extraordinary situations—typically where a taxpayer has pursued their rights diligently but was prevented from filing on time due to circumstances beyond their control.
Tax Court’s Analysis and Decision
In Aiello, the Tax Court carefully examined whether the facts justified equitable tolling. The court reiterated that:
"Equitable tolling is available only in rare cases where the petitioner demonstrates both diligence in pursuing their rights and that some extraordinary circumstance stood in their way and prevented timely filing."
Upon reviewing Aiello’s situation, the court found no evidence of extraordinary circumstances or sufficient diligence to warrant relief. Routine mistakes, misunderstandings, or simple neglect do not meet the threshold for equitable tolling. As a result, the court dismissed Aiello’s petition as untimely.
Implications and Takeaways
· Strict Deadlines Remain the Norm: Despite the Supreme Court’s recognition of equitable tolling, the Tax Court has made clear it will grant such relief only in exceptional cases.
· High Bar for Equitable Tolling: Taxpayers must show both diligent pursuit of their rights and extraordinary circumstances that directly caused the late filing.
· Practical Advice: Taxpayers and their advisors should treat the 30-day deadline for CDP petitions as effectively mandatory, ensuring prompt action to preserve their rights.
Conclusion
Aiello v. Commissioner reinforces that equitable tolling is not a safety net for routine oversights or delays in tax litigation. The Tax Court’s decision serves as a cautionary tale: missing a statutory deadline in a CDP case will almost always result in dismissal unless truly extraordinary circumstances are present and well documented.
