Besicorp v. Commissioner of Internal Revenue

23-296(L) Besicorp v. Commissioner of Internal Revenue In the United States Court of Appeals For the Second Circuit August Term, 2023 (Argued: February 5, 2024 Decided: June 29, 2026) Docket Nos. 23-296(L), 23-299 (Con), 23-302 (Con), 23-321 (Con), 23-353 (Con), 23-359 (Con) BESICORP GROUP, INC., DAY STORES, INC., HUMBOLDT SHELBY HOLDING CORPORATION, THE MARKELL COMPANY, INC., VANCE FINANCE AND HOLDING CORPORATION, SEASHORE BROADCASTING CORPORATION, Petitioners-Appellants, –v.– COMMISSIONER OF INTERNAL REVENUE, Respondent-Appellee. B e f o r e: LEVAL, CARNEY, and SULLIVAN, Circuit Judges. Six Taxpayers appeal from the Tax Court’s orders sustaining federal tax liens and proposed levies by the Internal Revenue Service (“IRS”) for collection of the Taxpayers’ outstanding tax liabilities. In earlier proceedings not challenged here, the Tax Court adjudicated the Taxpayers’ liabilities, which comprised many millions of dollars in unpaid taxes, penalties, and accrued interest. The Commissioner of Internal Revenue then sought to collect the Taxpayers’ liabilities through certain liens and levies on their property. Each Taxpayer invoked its right to have a collection due process (“CDP”) hearing conducted by the Appeals Office within the IRS. The Appeals Officer in each case sustained the Commissioner’s authority to collect the Taxpayers’ liabilities through liens and levies on their property. On appeal, the Tax Court upheld the Appeals Office’s determinations. In these consolidated appeals, the Taxpayers argue that, in upholding the Commissioner’s authority to collect the assessed liabilities by liens and levies, the Tax Court erroneously concluded that the Appeals Officer “verif[ied]” that “the requirements of any applicable law or administrative procedure have been met” in accordance with 26 U.S.C. § 6330(c)(1), a necessary predicate to the Commissioner’s assertion of liens and levies. The Appeals Officer’s rulings were incorrect, they say, because he failed “to obtain verification from the Secretary,” id., that the penalties imposed on the Taxpayers received written supervisory approval, as required by 26 U.S.C. § 6751(b)(1). In opposition, the Commissioner maintains primarily that the supervisory approval called for under Section 6751(b)(1) is not an “applicable” requirement covered by Section 6330(c)(1) in light of prior liability and penalty determinations against the Taxpayers, which he argues preclude the current challenges under res judicata. We conclude that the Taxpayers are correct. The verification obligation imposed on the Appeals Officer by Section 6330(c)(1) encompasses the supervisory approval requirement imposed by Section 6751(b)(1). To proceed with liens and levies, the government was required to show that the Appeals Officer verified that the penalties imposed on the Taxpayers received the required written supervisory approval. The failure to do so did not invalidate the penalties or overall tax liability owed by the Taxpayers, but it did invalidate the Appeals Officer’s determination that the liens were proper and the Taxpayers’ properties could be levied. Accordingly, we REVERSE the relevant portions of the Tax Court’s orders, and we remand for further proceedings consistent with this opinion. REVERSED AND REMANDED. PETER B. SIEGAL (Jasper G. Taylor III, Richard L. Hunn, Norton Rose Fulbright US LLP, Houston, TX, on the brief), Norton Rose Fulbright US LLP, Washington, DC, for Petitioners-Appellants. 2  ROBERT J. BRANMAN (David A. Hubbert, Jacob Earl Christensen, on the brief), Department of Justice, Tax Division, Washington, DC, for Respondent-Appellee. CARNEY, Circuit Judge: This case requires us to interpret provisions of the Internal Revenue Code (“I.R.C.” or “Code”), 26 U.S.C. §§ 6651 et seq., concerning the government’s ability to collect unpaid tax liabilities through liens and levies authorized by the Code. Petitioners-Appellants (the “Taxpayers”) are sophisticated entities that participated in what the Internal Revenue Service (the “IRS” or “Service”) concluded were tax shelter transactions designed to avoid the payment of taxes. The Service notified the Taxpayers that they owed many millions of dollars in unpaid taxes, penalties, and accrued interest, and the Tax Court adjudicated these liabilities in earlier proceedings not challenged here. The Commissioner of Internal Revenue (the “Commissioner”) then sought to collect these liabilities through the Code-authorized tax liens and levies on the Taxpayers’ properties. Each Taxpayer invoked its right to have a collection due process (“CDP”) hearing conducted by the Service’s Appeals Office in connection with the Commissioner’s issuance of Notices of Federal Tax Liens and Notices of Intent to Levy. The Appeals Officer in each case sustained the liens and proposed levies, and in doing so stated that he verified the Service’s compliance with all applicable laws and regulations in assessing the liabilities. The Tax Court upheld the Appeals Office’s determinations. Now, in consolidated appeals to our Court, the Taxpayers argue that the Tax Court erred in concluding that the Appeals Officer “obtain[ed] verification” that “the requirements of any applicable law or administrative procedure have been met,” as required by Section 6330(c)(1) of the Code. In particular, the Taxpayers contend that the 3 Appeals Officer failed to verify, and the Service failed to show, that the assessed penalties received the written supervisory approval mandated by Section 6751(b)(1). The Commissioner does not dispute that the Appeals Officer failed to verify that the assessed penalties received the requisite supervisory approval. Nor does the Commissioner contend that the required supervisory approvals were obtained before the imposition of penalties. Instead the Commissioner offers several responses: first, that res judicata bars the Taxpayers’ argument; next, that the written supervisory approval required by Section 6751(b)(1) is not an “applicable” requirement where, as here, the penalty was adjudicated in an earlier challenge; and finally, that, despite the literal language of Section 6330(c)(1), requiring the Appeals Officer to verify compliance with the supervisory approval mandate in a CDP hearing serves no bona fide purpose and therefore, notwithstanding the literal language of Section 6330(c)(1), the Appeals Officer’s failure should be treated as harmless error. We interpret these provisions literally, as we are required to do, and hold that Section 6751(b)’s supervisory approval requirement is a “requirement[] of . . . applicable law or administrative procedure” encompassed by Section 6330(c)(1). The Appeals Officer’s failure to verify that the penalties imposed on the Taxpayers received the requisite supervisory approval therefore invalidated the Appeals Office’s approval of the liens and proposed levies. Accordingly, we REVERSE those portions of the Tax Court’s orders that find that the verification requirement did not apply to the supervisory approval requirement and that the liens and proposed levies on the Taxpayers’ property were proper. We REMAND for further proceedings consistent with this opinion. 1 1Judge Sullivan joins in all parts of this opinion except the final paragraph of Section I of the Discussion, which he sees as unnecessary to our holding. 4  BACKGROUND I. Statutory framework A. Assessment of tax liability and related penalties The United States taxing system largely relies on “self-reporting.” United States v. Bisceglia, 420 U.S. 141, 145 (1975). Taxpayers file tax returns, on which they compute their net income and taxes, and pay the amount of tax indicated on said return. Only a fraction of tax returns are audited by the Service. If, after review of a taxpayer’s return, the Service determines that the taxpayer owes more tax than reported, it calculates a related “deficiency”: roughly speaking, the amount by which the tax reported is less than the tax in fact due. I.R.C. § 6211(a). 2 It then sends a “notice of such deficiency” to the taxpayer, announcing the amount due and related information. Id. §§ 6212(a), 7522(a). In its notice of deficiency, and in addition to the amounts presented as accrued interest due on the tax deficiency, the IRS may also assert claims for related penalties, identifying the authority for the penalty imposed. See id. §§ 6651 et seq. Penalties can be severe: for example, with respect to Besicorp, one Taxpayer in this appeal, the Service assessed a roughly $20 million penalty on a $50 million deficiency for its accuracy- related “gross valuation misstatements.” Joint App’x at 50; see I.R.C. § 6662(h). 2 More specifically: [T]he term ”deficiency” means the amount by which the tax imposed . . . exceeds the excess of . . . (1) the sum of (A) the amount shown as the tax by the taxpayer upon his return . . ., plus (B) the amounts previously assessed (or collected without assessment) as a deficiency, over — (2) the amount of rebates . . . made. I.R.C. § 6211(a). This definition is subject to certain additional rules, as set forth in Section 6211(b). Those additional rules do not bear on our discussion. 5  The Code imposes procedural requirements on the Service before it can impose penalties. One such requirement is found in Section 6751(b)(1), entitled “Approval of assessment.” 3 It provides: No penalty under this title shall be assessed unless the initial determination of such assessment is personally approved (in writing) by the immediate supervisor of the individual making such determination or such higher level official as the Secretary may designate. I.R.C. § 6751(b)(1). We refer to this as the “supervisory approval” requirement, and it is key here. A taxpayer who wishes to contest the deficiency or penalty amounts stated in a notice of deficiency may file a petition for a redetermination with the Tax Court within 90 days from the date of the notice’s issuance. See id. §§ 6213, 6214. 4 If the Tax Court issues a final decision upholding the stated deficiency and penalties, or if no timely petition for redetermination is filed, the Service may then take the pivotal step of “assess[ing]” the amount due by “recording the liability of the taxpayer in the office of the Secretary.” Id. § 6203; see id. §§ 6213(a), 6215(a). The assessment “fix[es] the amount payable.” Michael I. Saltzman & Leslie Book, IRS Prac. & Proc. ¶ 10.01[1] (2025) (citing I.R.C. § 6203). The Service must then notify the taxpayer of the unpaid tax liability “as soon as practicable, and within 60 days” of the assessment, and demand payment. I.R.C. § 6303(a). 3Section 6751 is entitled “Procedural requirements.” I.R.C. § 6751. It explains that its provisions use the word “penalty” to mean “any addition to tax or any additional amount.” Id. § 6751(c). Subsection (a) requires the Service to inform the taxpayer subject to a penalty the source of its authority to impose the penalty and “a computation of the penalty.” Id. § 6751(a). 4Alternatively, the taxpayer may pay the amount of deficiency and then bring suit for a refund in U.S. District Court or the Court of Federal Claims. See 14 Mertens Law of Fed. Income Tax’n § 49C:1 (July 2025 Update). 6  B. Collection of tax debt The Service may then take various steps toward collection. Notably, if after assessment and demand the taxpayer “neglects or refuses” to pay the outstanding liability, the Code provides that “the amount. . . shall be a lien in favor of the United States upon all property and rights to property, whether real or personal, belonging to such person.” Id. § 6321. The Service may also record a federal tax lien on the taxpayer’s property in the appropriate jurisdiction. See id. § 6323(f); see generally Saltzman & Book, supra, at ¶ 14A.04.5 More intrusively, it may levy (that is, seize) the taxpayer’s property and sell it to satisfy the tax debt. I.R.C. § 6331. In 1998, complaints of abusive collection tactics by the Service in its use of these tools (and other concerns) led to the passage of the Internal Revenue Service Restructuring and Reform Act of 1998 (the “Reform Act”), Pub. L. No. 105–206, 112 Stat. 685, establishing new procedural protections for taxpayers facing IRS collection actions. See Our Country Home Enters., Inc. v. Comm’r, 855 F.3d 773, 779 (7th Cir. 2017); Iames v. Comm’r, 850 F.3d 160, 162 (4th Cir. 2017). Paramount here, the Reform Act afforded a taxpayer subject to collection actions two separate rights: the right to a hearing after receiving a Notice of Federal Tax Lien, see I.R.C. § 6320, and the right to a hearing before the IRS levies on its property, see id. § 6330. These are the CDP hearings we have referred to above.6 5If it does so, the Service must “notify in writing the person . . . of the filing of a notice of lien” and provide post-recording process to the taxpayer who wishes to contest the lien or any element of it. I.R.C. § 6320. 6Section 6330(c)(1), the focus of our discussion here, is entitled “Requirement of investigation,” and provides in full, “The appeals officer shall at the hearing obtain verification from the Secretary that the requirements of any applicable law or administrative procedure have been met.” I.R.C. § 6330(c)(1). The Code section concerning the Service’s imposition of liens, Section 7  Officers within the Internal Revenue Service Independent Office of Appeals (“Appeals Office”) conduct the CDP hearings prescribed by the Reform Act. 7 Id. § 6320(b)(1). Appeals Officers (also known as Settlement Officers) are charged with “impartially resolving disputes between the government and taxpayers,” Our Country Home Enters., 855 F.3d at 779, while advocating for neither the taxpayer nor the Service. To preserve that impartiality, the Appeals Officer conducting the CDP hearing must have had “no prior involvement with respect to the unpaid tax” and is subject to other procedural constraints. I.R.C. §§ 6320(b)(3), 6330(b)(3). At the most general level, the Appeals Officer is charged with determining (i) whether a Notice of Federal Tax Lien should remain in effect, and (ii) if a Notice of Intent to Levy is at issue, whether the IRS may proceed with the proposed levy. See id. § 6320(b)(1) (liens); id. § 6330(b)(1) (levies). Before making those determinations, the Appeals Officer must permit the taxpayer “[to] raise . . . any relevant issue relating to the unpaid tax,” subject to certain limitations. 8 Id. § 6330(c)(2). Further, the Appeals Officer must consider “whether any proposed collection action balances the need for the efficient collection of taxes with the legitimate concern of the person that any collection 6320, incorporates the provisions concerning levies into those governing imposition of liens. Id. § 6320(c). The key difference in the CDP hearing aspect of the two sections is that the taxpayer’s opportunity for a CDP hearing follows the Service’s imposition of a federal tax lien, whereas it comes before the Service levies on a taxpayer’s property. But for both liens and levies, the verification requirement set out in Section 6330(c)(1) applies: the Appeals Officer conducting the CDP hearing shall verify the Service’s compliance with “any applicable law.” 7Before 2019, this office was simply called the Office of Appeals. Ruhaak v. Comm'r, 157 T.C. 103, 104 n.2 (2021). 8The taxpayer may raise “challenges to the existence or amount of the underlying tax liability” only if it “did not receive any statutory notice of deficiency for such tax liability or did not otherwise have an opportunity to dispute such tax liability.” I.R.C. § 6330(c)(2)(B). 8 action be no more intrusive than necessary.” Id. § 6330(c)(3)(C). Most salient here, the Appeals Officer must also “obtain verification from the Secretary [of the Treasury] that the requirements of any applicable law or administrative procedure have been met.” Id. § 6330(c)(1). Only after satisfying these requirements and considering the arguments and evidence presented by the Service and the taxpayer may the Appeals Officer issue a “Notice of Determination” upholding or rejecting the lien or proposed levy. CDP proceedings are subject to few formalities and are not the full-blown civil trials one might imagine. As one of our sister Circuits has observed, “calling the [CDP] proceeding a ‘hearing’ is somewhat misleading in that there is no obligation [for the Appeals Office] to conduct a face-to-face hearing, no formal discovery, no requirement for either testimony or cross-examination, and no transcript.” Our Country Home Enters., 855 F.3d at 780 (internal quotation marks omitted). A CDP hearing offers a taxpayer more than it had before the 1998 Reform Act, but in practice the CDP hearing can be “nothing more than an opportunity for an informal oral or written conversation with the IRS before [it] must pay a tax.” Id. Even so, an Appeals Officer’s failure to comply with the procedural requirements set forth in the statute can be consequential, and the Tax Court, which considers appeals from CDP hearings, may overturn a determination when it identifies such a failure. See I.R.C. § 6330(d)(1). In particular, if on review it is established that the Appeals Officer has not “verif[ied]” the Service’s compliance with “an[] applicable law or administrative procedure,” id. § 6330(c)(1), the Tax Court may strike the proposed lien or levy. See, e.g., Pfetzer v. Comm’r, 122 T.C.M. (CCH) 395, 2021 WL 6143712, at *5 (2008) (concluding that the Appeals Office abused its discretion in sustaining a Notice of Federal Tax Lien when the Appeals Officer “ha[d] not fulfilled her duty of verification under section 6330(c)(1)”); see generally Hoyle v. Comm’r, 131 T.C. 197 (2008) (“Hoyle I”). 9 II. Factual and procedural history Unless otherwise noted, the facts set forth below are drawn from the Tax Court record and are undisputed. The facts and procedural history in all six of these consolidated appeals are materially identical for purposes of our decision, as the parties acknowledge. Taxpayers’ Br. at 4−5; Comm’r Br. at 4. From 1999 to 2003, the Taxpayers—Besicorp Group, Day Stores, Humboldt Shelby Holding Corporation, the Markell Company, Vance Finance and Holding Corporation, and Seashore Broadcasting Corporation—each participated in what the IRS concluded were “intermediary tax shelter transactions designed to avoid the payment of taxes.” Joint App’x at 36 (Besicorp Notice of Determination dated Feb. 1, 2017). 9 In the underlying liability proceedings, the IRS determined that each Taxpayer was liable for deficiencies and penalties, and, on petitions for review of those determinations, the Tax Court upheld the noticed deficiencies and penalties. 10. No Taxpayer appears to have litigated any issue related to Section 6751’s supervisory approval requirement in those earlier proceedings. In the years after the Taxpayers’ liabilities for tax, penalties, and interest were affirmed, the IRS formally assessed the liabilities in accordance with Section 6215(a). It sent each Taxpayer a notice of deficiency and demanded payment. The Taxpayers failed 9 For brevity, we quote only from the materials filed in the appeal by Besicorp. 10Of the six Taxpayers, only one—Humboldt Shelby Holding Corporation—appealed the Tax Court’s decision on the liability ruling to this Court. On de novo review of that decision, we affirmed. See Humboldt Shelby Holding Corp. & Subs. v. Comm’r, 606 F. App’x 20, 21 (2d Cir. 2015) (affirming 107 T.C.M. (CCH) 1242, 2014 WL 1041485 (T.C. 2014)). Four of the other Taxpayers agreed to the identified tax liability in “stipulated decision[s], entered in the United States Tax Court.” Joint App’x at 36. The final Taxpayer, Vance Finance, does not appear to have stipulated to the Tax Court’s liability decision, but it did not appeal the decision and “did not dispute the liability” in its CDP hearing. Joint App’x at 544. 10 to pay. Accordingly, the IRS filed liens and sent each Taxpayer Notices of Federal Tax Liens and Notices of Intent to Levy. By the time the Service sent Notices of Intent to Levy to the Taxpayers, in late 2014 through early 2016, the Taxpayers owed accumulated amounts ranging from just under $13 million (for Day Stores) to almost $200 million (for Besicorp). These notices also informed each Taxpayer of the statutory right to a CDP hearing in connection with the liens and levies. In response, each Taxpayer made a token “offer in compromise” to the Service, proposing to settle its liabilities for $1,000. In connection with those offers in compromise, each represented to the Service that it was an “inactive corporation” without assets, checking a box that expressed “[d]oubt as to [c]ollectability,” and explaining “I have insufficient assets and income to pay the full amount.” Joint App’x at 59, 71. 11 The Taxpayers then each requested, and received, a CDP hearing. Each of these hearings was conducted by the same Appeals Officer within the Appeals Office. In his concluding Notices of Determination, which announced the results of the CDP hearings, the Appeals Officer sustained the IRS’s liens and proposed levy actions; rejected the offers in compromise, primarily on the ground that accepting the offers “would be detrimental to the interests of fair tax administration,” Joint App’x at 37; and upheld the assessed liabilities and penalties. In each Notice of Determination, the Appeals Officer wrote: I . . . verified the requirements of any applicable law or administrative procedure were met. IRS records confirmed the proper issuance of the notice and 11The proposed offers in compromise also requested that the IRS “accept the offer amount listed in this offer application as payment in satisfaction of any claims by the IRS against any person, as an alter ego, agent, nominee, transferee, or otherwise, for my outstanding tax debt.” See Joint App’x at 73. 11  demand, Notice of Intent to Levy, Notice of Federal Tax Lien (NFTL) filing and notice of a right to a [CDP] hearing. An assessment was properly made for each tax and period listed on the CDP notice. Notice and demand for payment was mailed to your last known address. There was a balance due when the Notice of Intent to Levy was issued and when the NFTL filing was requested. I had no prior involvement with respect to the specific tax periods either in Appeals or Compliance. I reviewed the Collection file, IRS records and information you provided. My review confirmed that the IRS followed all legal and procedural requirements, and the actions taken or proposed were appropriate under the circumstances. Id. at 32–33 (emphases added). The Notices of Determination made no express mention of Section 6751(b)’s supervisory approval requirement. The Taxpayers then each sought review in the Tax Court. They were able to obtain some discovery in these proceedings, and requested “all documents on which the Appeals officer based his conclusion that ‘the requirements of any applicable law or administrative procedure were met,’ including but not limited to the requirements of section 6751(b).” Joint App’x at 91 ¶ 2(w). The Service produced no documents in response to this request. Rather, as quoted by the Taxpayers, the Service took the position that “[b]ecause the applicability of the penalty at issue in this CDP case had already been conclusively determined by the Tax Court . . . , and the Tax Court’s prior, final decision ha[d] res judicata effect, no further verification of compliance with the requirements of [Section] 6751(b) was required.” Id. ¶ 2(x) (internal quotation marks omitted). In all six cases, the Commissioner then moved the Tax Court for summary judgment. The Taxpayers opposed, asserting that the Appeals Officer had failed in his 12 duty to verify the Service’s compliance with Section 6751(b)(1) in assessing penalties. They also claimed he had abused his discretion by rejecting the Taxpayers’ offers in compromise. The Special Trial Judge assigned to the cases by the Tax Court granted in part and denied in part the Commissioner’s motions in an unpublished order. She found no abuse of discretion in the Appeals Officer’s rejection of the offers in compromise. But she also concluded that the Appeals Officer’s “failure to verify [the] IRS’[s] compliance with section 6751(b) was a failure to meet the verification requirement of section 6630(c)(1) [sic: 6330(c)(1)] and therefore was an abuse of discretion.” Joint App’x at 115. She thus denied the Service summary judgment in part, with the effect that, although the Taxpayers’ penalty assessment and overall tax liability were unaffected, the Service’s liens and proposed levies could not be enforced as to the penalties. Only weeks later, however, in a published Tax Court Memorandum, a Tax Court Judge reached the opposite conclusion about the requirements of Section 6330 and Section 6751(b). See Warner Enters., Inc. v. Comm’r, 124 T.C.M. (CCH) 98, 2022 WL 3584090 (T.C. 2022), appeal filed No. 24-611 (2d Cir. 2024). 12 In Warner Enterprises, the Tax Court held that “where the Court previously adjudicated and entered a decision determining the applicability of penalties,” a CDP Appeals Officer need not verify compliance with the supervisory approval requirement of Section 6751(b)(1). Id. at *4. Instead, it ruled, the Appeals Officer “merely needs to determine that the penalty was properly assessed.” Id. “To permit otherwise,” it reasoned, “would place the administrative agency in review of the Court.” Id. And because no authority “would 12The appeal in Warner Enterprises has been held in abeyance pending our Court’s decision in the consolidated Besicorp cases. Order Granting Unopposed Motion to Stay Appeal, Warner Enters., Inc., No. 24-611 (2d Cir. Mar. 28, 2024), Dkt. No. 18. 13 permit the Court to set aside the prior—and now final—decision” on the underlying liability, “verification of IRS compliance with [S]ection 6751(b) at this stage would serve no purpose.” Id. at *5. In short, the Tax Court in Warner Enterprises squarely rejected the Taxpayers’ argument that Section 6330(c)(1)’s verification requirement “includes confirmation of whether the supervisory approval requirement of section 6751(b) has been met.” Id. at *4. Soon after Warner Enterprises issued, the Special Trial Judge assigned these Taxpayers’ cases vacated her earlier decisions, and, in a new set of Orders and Decisions, granted in full the Commissioner’s motions for summary judgment. Citing Warner Enterprises, the judge now accepted the Commissioner’s argument that “compliance with section 6751(b) is not part of the verification requirements of section 6330(c)(1) because th[e] [Tax] Court . . . already conclusively determined the applicability of penalties.” Joint App’x at 125. She ruled that the Appeals Officer in the case at bar complied with the requirements of Section 6330(c)(1), on the ground that, as in Warner Enterprises, ”’the [Tax] Court previously adjudicated and entered a decision determining the applicability of penalties,’” so that the Appeals Officer “’merely need[ed] to determine that the penalty was properly assessed.’” Id. (quoting Warner Enters., Inc., 2022 WL 3584090, at *4). The Taxpayers appealed to our Court, challenging only this part of the Tax Court’s decision. Taxpayers’ Br. at 7–8. The Taxpayers do not challenge the portions of the Tax Court’s orders affirming the Appeals Officer’s rejection of the Taxpayers’ offers in compromise, and do not challenge the IRS’s assessments of their very large tax liabilities, including penalties. Rather, they contend that because the Service did not show that the Appeals Officer satisfied the verification requirements of Section 6330(c)(1) with respect to the supervisory approval requirement of Section 6751(b)(1), it may not use liens and levies to collect the amounts of the penalties that are owed. 14  On appeal, we consolidated the six cases. DISCUSSION We review de novo the Tax Court’s grant of summary judgment. Williams v. Comm’r, 718 F.3d 89, 91 (2d Cir. 2013). In doing so, we “must also review the decision by the Appeals Office.” Id. We review the Appeals Office’s determinations for abuse of discretion. Id. at 92. 13 The Taxpayers argue that Section 6330(c)(1) obligates the Appeals Officer in every CDP hearing to verify the Service’s compliance with Section 6751(b)(1)—that is, its satisfaction of the basic requirement that no penalty be assessed “unless the initial determination of such assessment is personally approved (in writing) by the immediate supervisor of the individual making such determination.” I.R.C. § 6751(b)(1). Failure to do so, they urge, prevents the Service from using the federal tax liens authorized by Section 6323 and the levies authorized by Section 6331 to collect the assessed liabilities. For his part, the Commissioner maintains that where, as here, the underlying liabilities have already been conclusively determined in earlier IRS proceedings, verification that supervisory approval was obtained would “serve[] no bona fide purpose” at the CDP hearing stage. Comm’r Br. at 33. And so, he argues, the supervisory approval requirement is not correctly understood to be an “applicable law or administrative procedure” under Section 6330(c)(1). Id. (quoting I.R.C. § 6330(c)(1)). 13As relevant here, Section 7482 of the Code generally gives the Courts of Appeals “exclusive jurisdiction to review the decisions of the Tax Court, . . . in the same manner and to the same extent as decisions of the district courts in civil actions tried without a jury,” subject only to further review by the Supreme Court upon certiorari. I.R.C. § 7482(a)(1). On such review, our Court has the power “to affirm or, if the decision of the Tax Court is not in accordance with law, to modify or to reverse the decision of the Tax Court, with or without remanding the case for a rehearing, as justice may require.” Id. § 7482(c)(1). 15 He urges that, in such cases, the Appeals Officer is under no obligation at all to verify that the Service obtained supervisory approval. All challenges related to the penalties that required supervisory approval have been settled in the earlier proceedings, he maintains, and the related verification requirement has become meaningless. For the reasons set forth below, we cannot agree. I. Section 6330(c)(1) requires the Appeals Officer in a CDP hearing to verify that “the requirements of any applicable law or administrative procedure” have been met without regard to the stage of the Service’s proceedings. We begin, as always, with the text of the statute whose meaning the parties dispute. Bartenwerfer v. Buckley, 598 U.S. 69, 74 (2023). Section 6330(c)(1) states that it imposes a “[r]equirement of investigation” on the Appeals Officer conducting a CDP hearing. In language as unmistakably mandatory as it is unmistakably broad, it provides: “The appeals officer shall at the hearing obtain verification from the Secretary that the requirements of any applicable law or administrative procedure have been met.” I.R.C. § 6330(c)(1) (emphases added). The Code does not specify which requirements of law or administrative procedure must be verified by the Appeals Officer at the hearing. But the Tax Court has held that the “basic” requirements for which an Appeals Officer must obtain Section 6330(c)(1) verification, Dinino v. Comm’r, 98 T.C.M. (CCH) 559, 2009 WL 4723652, at *7 (T.C. 2009), include at least these four: (i) that a valid assessment was made; (ii) that notice of the assessment was given, and demand for payment made, to the taxpayer; (iii) that the taxpayer failed to pay; and 16  (iv) that the IRS issued a notice of the recorded lien or notice of intent to levy, together with a notice of the taxpayer’s right to a hearing. See Ron Lykins, Inc. v. Comm’r, 133 T.C. 87, 97 (2009). Section 6330(c)(1)’s verification mandate has been held to apply to other legal requirements as well: for example, the Tax Court has ruled that the Appeals Officer must verify that before the deficiency was assessed, the notice of deficiency was mailed to the taxpayer at its last known address. Hoyle I, 131 T.C. at 200 (observing that “[o]ne requirement of applicable law” subject to Section 6330(c)(1) verification is the Commissioner’s obligation to “duly mail[] a notice of deficiency” to a taxpayer). As we have said, the question in the cases before us now is whether Section 6751(b)(1)’s supervisory approval requirement is a “requirement[] of any applicable law or administrative procedure” that is subject to Section 6330(c)(1)’s verification mandate. I.R.C. § 6330(c)(1). Looking to the literal meaning of the statutory language, we think the presumptive answer to that question has to be “yes.” Section 6330(c)(1) applies to requirements set forth in “any” applicable law or administrative procedure. Id. The Supreme Court has underscored that “the word ‘any’ . . . has an ‘expansive meaning.’” Republic of Iraq v. Beaty, 556 U.S. 848, 856 (2009) (quoting United States v. Gonzales, 520 U.S. 1, 5 (1997)). Current dictionaries tell us the same, with one defining “any” as “one or some indiscriminately of whatever kind.” Any, Merriam-Webster's Unabridged Dictionary, https://unabridged.merriam-webster.com/unabridged/any (last visited Dec. 8, 2025). And Section 6751(b)(1) is equally plain: “No penalty under this title shall be assessed unless the initial determination of such assessment is personally approved (in writing) by the immediate supervisor of the individual making such determination or such higher level official as the Secretary may designate.” I.R.C. § 6751(b)(1) (emphasis 17 added). We find it difficult to say that, literally read, this statute is not an “applicable law” as to any case in which penalties are imposed. 14 The Commissioner contends, however, that the Appeals Officer’s obligation to verify that supervisory approval for penalties was obtained falls away when the taxpayer’s liability for the deficiency, penalties, and interest—the basis for the Service’s lien and desired levies—has already been “conclusively determined” by the Service either in prior proceedings or in a stipulation by the taxpayer. Comm’r Br. at 24. He relies on the word “applicable” in Section 6330(c)(1) to support his reading, and presses the view that, “[a]t the time of the CDP hearings, . . . [Section] 6751(b)(1)’s supervisory approval requirement was no longer ‘applicable’ because each taxpayer’s liability for the penalties had already been conclusively determined by the Tax Court, [and] the appeals officer was bound by those determinations . . . .” Comm’r Br. at 33. The Appeals Officer could not overturn those determinations, he says, and so the Service’s earlier compliance—or non-compliance—with the supervisory approval requirement became irrelevant. We must decline the Commissioner’s invitation to read into Section 6330(c)(1) the limitation that Section 6751(b)(1) was “applicable” before the underlying tax liabilities and penalties were finally adjudicated in the Tax Court, but not thereafter. Nothing in the text of Section 6330(c)(1) suggests that the scope of the Appeals Officer’s verification obligation is altered by the happenstance that the underlying liabilities were previously litigated and decided. See Bates v. United States, 522 U.S. 23, 29 (1997) (“[W]e ordinarily resist reading words or elements into a statute that do not appear on its face.”). 14Even the Commissioner concedes that, “if [Section] 6751(b)(1) applies to a penalty that becomes the subject of a CDP hearing, then the appeals officer generally should obtain verification that proper supervisory approval of the penalty was obtained.” Comm’r Br. at 24 (emphasis added). 18 Congress expressly excluded certain taxes from Section 6751(b)(1)’s supervisory approval requirements. See I.R.C. § 6751(b)(2); ATL & Sons Holdings, Inc. v. Comm’r, 152 T.C. 138, 144, 148–54 (2019) (describing types of penalties exempt from the supervisory approval requirement). 15 But it did not do so here, and the Commissioner does not (and cannot reasonably) contend that any of these stated exceptions actually applies to the penalties that the IRS seeks to collect in the cases now before us. The Code broadly defines “penalty” as “any addition to tax or any additional amount,” I.R.C. § 6751(c), further signaling an inclusive intention on Congress’s part. Taken together, these observations reinforce that in Section 6751, “any” means “any.” The Commissioner also fails to persuade when he invokes other provisions within Section 6330 to support his view that verification of the penalties’ supervisory approval is not required for the Service to assert liens and to levy on taxpayers’ property. For example, the Commissioner points to Section 6330(c)(2)(B), which permits a taxpayer to raise “challenges to the existence or amount of the underlying tax liability” at CDP hearings only if the taxpayer “did not receive any statutory notice of deficiency for such tax liability or did not otherwise have an opportunity to dispute such tax liability.” Id. § 6330(c)(2); see ante, note 8; Comm’r Br. at 21–22, 29–32. As the Fourth Circuit has explained, Section 6330(c)(2)(B) “incorporate[s] the principle[] of claim preclusion . . . into the CDP context,” an
