148 F.4th 820
6th Cir.2025Background
- Taxpayer Oquendo received a notice of tax deficiency from the IRS regarding her 2022 returns, including denied credits and claimed penalties.
- Oquendo filed a petition for redetermination with the U.S. Tax Court five months after the notice was mailed, missing the statutory ninety-day deadline.
- She argued the delay was because the notice was sent to her old address; she only learned of it after a subsequent collection notice was sent to her representative in October 2023.
- The IRS moved to dismiss, arguing the late filing deprived the Tax Court of jurisdiction under I.R.C. § 6213(a).
- The Tax Court agreed with the IRS, holding it had no jurisdiction due to the untimely petition and that equitable tolling was not available.
- Oquendo appealed, challenging both the jurisdictional interpretation of the deadline and the denial of equitable tolling.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Is the 90-day filing deadline in § 6213(a) jurisdictional? | It is a nonjurisdictional claims-processing rule; not a limit on the court’s power. | It is jurisdictional and strictly bars late petitions from being heard. | Not jurisdictional; filing deadline is a claims-processing rule. |
| Is § 6213(a) subject to equitable tolling? | Deadline should be equitably tolled because taxpayer did not receive timely notice; taxpayer acted diligently after learning of the deficiency. | Equitable tolling not available if the rule is jurisdictional; taxpayer’s lateness precludes relief. | Deadline is subject to equitable tolling. |
| Did the Tax Court err by not considering equitable tolling? | Tax Court should have assessed her entitlement to tolling given the lack of actual notice. | No, because jurisdiction was lacking; equitable tolling was irrelevant. | Yes; remand for Tax Court to consider equitable reasons on the merits. |
| Precedential effect of prior circuit cases treating deadline as jurisdictional | Past statements are contrary to recent Supreme Court distinctions between jurisdictional and nonjurisdictional rules. | Circuit precedent requires treating deadline as jurisdictional. | Supreme Court precedent supersedes, requiring a modern approach. |
