MARK BULLER, SARAH BEATTY,

Petitioners-Appellants,

v.

COMMISSIONER OF INTERNAL REVENUE,

Respondent-Appellee.

Appeal from the United States Tax Court No. 25011-22, Kathleen Kerrigan, Chief Judge.

Before: CABRANES, LOHIER, and SULLIVAN, Circuit Judges.

Mark Buller and Sarah Beatty (together, “Petitioners”) appeal from a judgment of the United States Tax Court (Kerrigan, C.J.) dismissing their petition challenging the determination of the Commissioner of Internal Revenue concerning their income-tax deficiency for 2018. Because the petition was filed more than ninety days after the Internal Revenue Service mailed the deficiency notice, the Tax Court concluded that I.R.C. § 6213(a) deprived it of jurisdiction to review the petition. We disagree. In light of recent Supreme Court decisions, we hold that the filing deadline in section 6213(a) is a nonjurisdictional, claim- processing rule. We further hold that the deadline is subject to equitable tolling. Accordingly, we REVERSE the judgment of the Tax Court and REMAND for consideration of whether Petitioners are entitled to equitable tolling.

RICHARD J. SULLIVAN, Circuit Judge:

Mark Buller and Sarah Beatty (together, “Petitioners”) appeal from a

judgment of the United States Tax Court (Kerrigan, C.J.) dismissing their petition

challenging the determination of the Commissioner of Internal Revenue (the

“Commissioner”) concerning their income-tax deficiency for 2018. Because the

petition was filed more than ninety days after the Internal Revenue Service (the

“IRS”) mailed the deficiency notice, the Tax Court concluded that I.R.C. § 6213(a)

2 deprived it of jurisdiction to review the petition. We disagree. In light of recent

Supreme Court decisions, we hold that the filing deadline in section 6213(a) is a

nonjurisdictional, claim-processing rule. We further hold that this filing deadline

is subject to equitable tolling. Accordingly, we REVERSE the judgment of the Tax

Court and REMAND for consideration of whether Petitioners are entitled to

equitable tolling.

I. BACKGROUND

On August 22, 2022, the IRS sent a notice of deficiency to Petitioners

regarding their 2018 income-tax returns. Under I.R.C. § 6213(a), a petition to the

United States Tax Court challenging a notice of deficiency must be filed within

ninety days from the date the notice was issued. As it turned out, Petitioners’

counsel missed that deadline and filed the petition nine days late. On January 27,

2023, the IRS filed a motion in the Tax Court to dismiss the petition for lack of

jurisdiction. Petitioners opposed that motion, arguing that this filing deadline in

section 6213(a) is nonjurisdictional and subject to equitable tolling and that it

would be more efficient to consolidate their petition with other related petitions.

The Tax Court found that the IRS properly mailed the notice of deficiency to

Petitioners and that Petitioners failed to file their petition by section 6213(a)’s

3 deadline. The Tax Court therefore concluded that it lacked jurisdiction and

dismissed the petition. Petitioners timely appealed.

II. STANDARD OF REVIEW

We review de novo the Tax Court’s dismissal for lack of jurisdiction. See

Borenstein v. Comm’r,

(2d Cir. 2019). We also review de novo the

question of whether a statutory deadline is subject to equitable tolling. See Doe v.

United States,

(2d Cir. 2023).

III. DISCUSSION

A. Section 6213(a)’s filing deadline is a nonjurisdictional, claim-

processing rule.

Petitioners first argue that the filing deadline in section 6213(a) is a

nonjurisdictional, claim-processing rule. Section 6213(a) states, in relevant part,

Within 90 days, or 150 days if the notice is addressed to a person outside the United States, after the notice of deficiency . . . is mailed (not counting Saturday, Sunday, or a legal holiday in the District of Columbia as the last day), the taxpayer may file a petition with the Tax Court for a redetermination of the deficiency.

I.R.C. § 6213(a).

We have long described section 6213(a)’s filing deadline as jurisdictional in

nature. See, e.g., Galvin v. Comm’r,

, 166 (2d Cir. 1956); Vibro Mfg. Co.

v. Comm’r,

(2d Cir. 1963); Deutsch v. Comm’r,

(2d 4 Cir. 1979); Tadros v. Comm’r,

(2d Cir. 1985); Hoffenberg v. Comm’r,

(2d Cir. 1990); Sicari v. Comm’r,

(2d Cir. 1998).

In recent years, however, the Supreme Court has sought to “bring some discipline”

to the use of the word “jurisdiction,” observing that judicial opinions have often

stated that the court was dismissing the case for lack of jurisdiction without

explicitly considering whether the procedural rule actually “govern[ed] the court’s

adjudicatory capacity.” Henderson ex rel. Henderson v. Shinseki,

(2011); see also Arbaugh v. Y&H Corp.,

(2006). The Court has noted

that such imprecision can have significant consequences for both litigants and

courts because jurisdictional provisions “cannot be waived or forfeited, must be

raised by courts sua sponte, and . . . do not allow for equitable exceptions.” Boechler,

P.C. v. Comm’r,

(2022).

The question before us, then, is whether our cases that described the filing

deadline in section 6213(a) as jurisdictional – but offered no explanation for that

conclusion – remain good law after Arbaugh and its progeny. “In general, a panel

of this Court is bound by the decisions of prior panels until such time as they are

overruled either by an en banc panel of our Court or by the Supreme Court.” Lotes

Co. v. Hon Hai Precision Indus. Co.,

(2d Cir. 2014) (internal

5 quotation marks omitted). But a narrow exception to this rule applies “where

there has been an intervening Supreme Court decision that casts doubt on our

controlling precedent.”

(internal quotation marks omitted); see also In re Zarnel,

(2d Cir. 2010). The Supreme Court has also held that a prior

decision that “simply states that the court is dismissing ‘for lack of jurisdiction’

when some threshold fact has not been established” should “receive[] no

precedential effect.” Wilkins v. United States,

, 160 (2023) (internal

quotation marks omitted); see also Donnelly v. Controlled Application Rev. & Resol.

Program Unit,

, 55 (2d Cir. 2022). We therefore must decide with fresh

eyes whether the filing deadline in section 6213(a) is a limitation on the Tax Court’s

jurisdiction.

The Supreme Court has explained that “the [g]overnment must clear a high

bar to establish that a [procedural rule] is jurisdictional.” United States v. Wong,

, 409 (2015). And while Congress does not need to “incant magic

words,” “traditional tools of statutory construction must plainly show that

Congress imbued a procedural bar with jurisdictional consequences.” Id. at 410

(internal quotation marks omitted). In other words, the jurisdictional nature of the

procedural requirement “must . . . be clear; it is insufficient that a jurisdictional

6 reading is ‘plausible,’ or even ‘better,’ than nonjurisdictional alternatives.” MOAC

Mall Holdings LLC v. Transform Holdco LLC,

(2023); see also Boechler,

(“Where multiple plausible interpretations exist – only one of which

is jurisdictional – it is difficult to make the case that the jurisdictional reading is

clear.”). Indeed, the Supreme Court has observed that “most time bars are

nonjurisdictional” claim-processing rules that “seek to promote the orderly

progress of litigation, but do not deprive a court of authority to hear a case.” Wong,

575 U.S. at 410 (emphasis added) (internal quotation marks omitted).

Because Congress has not clearly imbued the filing deadline in section

6213(a) with jurisdictional consequences, we hold that it is a nonjurisdictional,

claim-processing rule. Section 6213(a) “speaks only to a claim’s timeliness, not to

a court’s power,” which is “mundane statute-of-limitations language.” Id. In fact,

the language used in section 6213(a) simply states that “the taxpayer may file a

petition,” I.R.C. § 6213(a) (emphasis added), and the Supreme Court has held that

similarly permissive language “does not speak in jurisdictional terms,” Sebelius v.

Auburn Reg’l Med. Ctr.,

(2013) (internal quotation marks omitted)

(“Section 1395oo(a)(3) instructs that a provider of services ‘may obtain a hearing’

by the Board regarding its reimbursement amount if ‘such provider files a request

7 for a hearing within 180 days after notice of the intermediary’s final

determination.’”). Moreover, the filing deadline in section 6213(a) is directed at

the taxpayer, rather than the court, which indicates that it “do[es] not speak to a

court’s authority or refer in any way to the jurisdiction of the . . . courts,” but rather

“speak[s] to a party’s procedural obligations.” Fort Bend County v. Davis,

(2019) (alterations accepted, citation omitted, and internal quotation

marks omitted).

Additionally, there is no “clear tie” between the Tax Code’s jurisdictional

provisions and section 6213(a)’s filing deadline. MOAC Mall Holdings LLC,

(internal quotation marks omitted); see also Wong, 575 U.S. at 411

(“Congress’s separation of a filing deadline from a jurisdictional grant indicates

that the time bar is not jurisdictional.”). Indeed, the word “jurisdiction” does not

even appear in the relevant sentence of section 6213(a). And unlike other

provisions of the Tax Code, such as section 6015(e)(1)(A), which “expressly

condition[s] the Tax Court’s jurisdiction on the timely filing of a petition,”

Matuszak v. Comm’r,

(2d Cir. 2017), section 6213(a)’s filing

deadline contains no express link to the Tax Court’s jurisdiction. It also bears

noting that Congress has amended section 6213 multiple times since 1924 yet

8 “declined . . . to say anything specific about whether the [filing deadline] imposes

a jurisdictional bar.” Wong, 575 U.S. at 412.

Recognizing that section 6213(a)’s “bare text speaks to jurisdiction

implicitly” at best, Comm’r Br. at 19 (emphasis added), the Commissioner falls back

on a number of other arguments, none of which is availing. The Commissioner

first points to a later sentence in section 6213(a) that states: “The Tax Court shall

have no jurisdiction to enjoin any action or proceeding or order any refund under

this subsection unless a timely petition for a redetermination of the deficiency has

been filed and then only in respect of the deficiency that is the subject of such

petition.” But once again, a requirement “does not become jurisdictional simply

because it is placed in a section of a statute that also contains jurisdictional

provisions.” Auburn,

. Furthermore, the Supreme Court rejected an

analogous argument in Boechler, explaining that “the prospect that [the statute]

deprives the Tax Court of authority to issue an injunction in a subset of appeals”

does not itself establish a clear jurisdictional statement.

. If

anything, the clear statement of jurisdiction with respect to injunctive relief

“highlights the lack of such clarity” earlier in the statutory provision.

9 The Commissioner also emphasizes that “[b]efore 2023, every federal

appellate court to reach the question had held that [s]ection 6213(a)’s deadline is

jurisdictional.” Comm’r Br. at 53. But while it is true that a requirement may be

treated as “jurisdictional when a long line of Supreme Court decisions left

undisturbed by Congress attached a jurisdictional label to the prescription,” Davis,

(emphasis added) (alterations accepted and internal quotation

marks omitted), no such line of Supreme Court decisions exists here. And “[a]

handful of lower court opinions [cannot] stand in for a ruling of [the Supreme]

Court, especially where some of th[o]se decisions contain only fleeting references

to jurisdiction.” Wilkins,

.

Finally, the Commissioner argues that treating section 6213(a)’s filing

deadline as nonjurisdictional cannot be reconciled with I.R.C. § 7459(d), which

states that “a decision of the Tax Court dismissing the proceeding shall be

considered as its decision that the deficiency is the amount determined by the

Secretary . . . unless the dismissal is for lack of jurisdiction.” The Commissioner

contends that treating section 6213(a)’s filing deadline as nonjurisdictional would

therefore harm taxpayers who file untimely petitions because “a non-jurisdictional

dismissal would lock in the deficiency amount for such taxpayers.” Comm’r Br.

10 at 13. But even if we accepted the Commissioner’s interpretation of section

7459(d), it would not change the result of our analysis. As the Third Circuit

explained when addressing this very argument, “this situation presents itself only

if a taxpayer files a late petition for redetermination of a deficiency, the Tax Court

dismisses his or her petition, [and] the taxpayer then pays the disputed deficiency,

files for a refund, gets denied, and then sues in federal court challenging the

denial,” which the Third Circuit viewed as a “theoretical possibility” that is

“seldom, if ever, to occur.” Culp v. Comm’r,

, 202 (3d Cir. 2023).

For all these reasons, we hold that the filing deadline in section 6213(a) is –

quite clearly – a nonjurisdictional, claim-processing rule.

B. Section 6213(a)’s filing deadline is subject to equitable

tolling.

Having concluded that section 6213(a)’s filing deadline is a

nonjurisdictional claim-processing rule, we must next address whether it is subject

to equitable tolling. The Supreme Court has explained that “[e]quitable tolling is

a traditional feature of American jurisprudence and a background principle

against which Congress drafts limitations periods.” Boechler, 596 U.S. at 208–09.

As a result, “nonjurisdictional limitations periods are presumptively subject to

11 equitable tolling.” Id. at 209. In Boechler, the Supreme Court held that I.R.C.

§ 6330(d)(1) was subject to equitable tolling. The rationale underlying that

decision applies with equal force to section 6213(a). Like section 6330(d)(1), section

6213(a) “does not expressly prohibit equitable tolling, and its short . . . time limit

is directed at the taxpayer, not the court.” Id. Similarly, section 6213(a)’s “deadline

. . . appears in a section of the Tax Code that is unusually protective of taxpayers

and a scheme in which laymen, unassisted by trained lawyers, often initiate the

process.” Id. (internal quotation marks omitted).

Section 6213(a)’s deadline is also different from the deadline in section 6511

for claiming a credit or refund of an overpayment, which the Supreme Court held

was not subject to equitable tolling in United States v. Brockamp,

(1997).

Specifically, section 6511 “sets forth its time limitations in unusually emphatic

form” and “in a highly detailed technical manner, that, linguistically speaking,

cannot easily be read as containing implicit exceptions.”

. The Court also

noted that section 6511 “reiterates its limitations several times in several different

ways” and sets forth six “explicit exceptions to its basic time limits.”

.

The same cannot be said for section 6213(a). Indeed, section “6213(a)’s exceptions

are neither many (the three here are less than the six in Brockamp . . . ), nor are they

12 set out explicitly or in a highly detailed technical manner, and they do not contain

substantive limitations on the amount of recovery.” Culp, 75 F.4th at 203–04

(internal quotation marks omitted).

Furthermore, section 6213(a)’s deadline “serves a far more limited and

ancillary role in the tax collection system.” Boechler,

; see also Reply

Br. at 27 (“Equitable tolling of the 90-day deadline has the potential to impact

.011% of the tax base.”). The Commissioner admits that only one million taxpayers

received a deficiency notice and less than 21,000 deficiency petitions were filed in

2023, see Comm’r Br. at 66 & n.20, which pales in comparison to the over 90 million

tax refunds that were implicated in Brockamp, see

. Accordingly, it

is unlikely “that the possibility of equitable tolling for the relatively small number

of petitions at issue in this case will appreciably add to the uncertainty already

present in the process.” Boechler,

. And there is no reason to believe

that applying equitable tolling to section 6213(a)’s filing deadline “will encourage

more taxpayers to file untimely petitions in the (longshot) hopes of bringing a

successful equitable tolling argument.” Culp, 75 F.4th at 204.

As a result, we hold that section 6213(a)’s filing deadline is subject to

equitable tolling. Because the Tax Court did not consider whether Petitioners are

13 entitled to equitable tolling, we remand this case so that the Tax Court can make

that determination in the first instance.

IV. CONCLUSION

For all the foregoing reasons, we REVERSE the judgment of the Tax Court

and REMAND for consideration of whether Petitioners are entitled to equitable

tolling.
