Commissioner v. Zuch Limits Tax Court Review After the IRS Ends a Levy

Read the source decision or official decision listing.

A taxpayer may win the immediate collection battle yet still face an unresolved dispute about a payment or credit. Commissioner v. Zuch, 605 U.S. 422 (2025), addresses the Tax Court’s power in that situation.

The Collection Due Process Setting

The IRS proposed a levy to collect an alleged unpaid balance. Jennifer Zuch pursued collection due process review and disputed the IRS’s treatment of a payment. While the case continued, the IRS applied later overpayments, reduced the balance to zero, and stopped pursuing the levy.

The Tax Court dismissed. The Third Circuit disagreed, reasoning that the court could still resolve the underlying dispute.

The Supreme Court’s Jurisdictional Holding

The Supreme Court held that 26 U.S.C. § 6330 did not authorize continued review after the levy ended. The statutory proceeding concerns the appeals officer’s determination whether a proposed levy may proceed. Once there was no levy basis, there was no relevant collection determination left to review under that provision.

Collection Procedure Is Not Always Liability Review

The decision underscores the difference between contesting collection and obtaining a judicial determination of liability or account treatment. A collection case may allow predicate issues while a levy remains live, but it does not necessarily provide an independent forum after collection ends.

Other remedies have separate prerequisites and deadlines. The available path can depend on payment, a refund claim, notices, and prior opportunities to contest liability.

Why Procedure Must Be Planned Early

Tax controversies can involve the amount owed, authority to collect, payment application, penalties, and forum. Resolving one does not automatically resolve others. Taxpayers should preserve transcripts, notices, payments, and correspondence and seek advice before deadlines expire.

Key Takeaways

• Section 6330 review is tied to an active levy determination.
• Ending a levy may end that Tax Court proceeding.
• Liability or refund disputes may require another path.
• Forum and deadline analysis are central.
