§ 7701(o) Reaches Mechanically Compliant TCJA “Mismatch” Shelters: Integrated Series Treated as the Transaction

Case: Liberty Global, Inc. v. United States (No. 23-1410)  |  Court: Tenth Circuit  |  Date: April 21, 2026

I. Introduction

Liberty Global, Inc. (“LGI”), the U.S. parent of a multinational consolidated group, sought a refund of roughly $110 million after implementing “Project Soy,” a four-step, closely timed restructuring and sale designed to exploit a “last day of year rule/mismatch” created by the 2017 Tax Cuts and Jobs Act (“TCJA”). The plan generated large “earnings and profits” (“E&P”) in foreign subsidiaries (steps 1–3) and then, in step 4, sold a controlled foreign corporation interest so that the gain could be treated as a dividend and offset with the participation exemption deduction under 26 U.S.C. § 245A.

The key appellate issue was narrow but consequential: whether the codified economic substance doctrine, 26 U.S.C. § 7701(o), is “relevant” to Project Soy—i.e., whether the government may disallow a tax benefit even when the transactions arguably satisfy the literal, mechanical conditions of the Code. Numerous business groups participated as amici.

II. Summary of the Opinion

The Tenth Circuit (Murphy, J.) affirmed summary judgment for the United States. The court held:

• The codified economic substance doctrine applies to transactions that mechanically comply with the Tax Code; it is not merely an interpretive tool that cannot “override” literal terms.
• The proper “transaction” for analysis was the integrated series—Project Soy as a whole—not isolated steps. A series cannot be immunized by embedding “basic business transactions” within it.
• Because LGI admitted steps 1–3 failed both § 7701(o) prongs, those steps were disregarded, eliminating the E&P needed to support the § 245A deduction; step 4 then produced taxable gain.
• LGI’s alternative arguments were waived under circuit forfeiture principles because it litigated only “relevance” below and made binding admissions as to economic substance.

Judge Eid dissented, arguing § 7701(o) requires a meaningful threshold “relevance” inquiry distinct from the two-prong test, and that the majority’s approach effectively allows an atextual, purpose-driven override of Code provisions.

III. Analysis

A. Precedents Cited (and How They Shaped the Decision)

1. The Tenth Circuit’s economic substance line: literal compliance is not enough

• Blum v. Comm'r, 737 F.3d 1303 (10th Cir. 2013) and Sala v. United States, 613 F.3d 1249 (10th Cir. 2010): The majority relied on these to reiterate a core rule of Tenth Circuit tax law: transactions may be disregarded as shams even if they “comply with the literal terms of the tax code.” This directly defeated LGI’s primary framing that “mechanical” statutory compliance forecloses § 7701(o).
• Rogers v. United States, 281 F.3d 1108 (10th Cir. 2002) and Bohrer v. Comm'r, 945 F.2d 344 (10th Cir. 1991): Cited to show the durability and breadth of sham/economic substance analysis in the circuit, including agreement with other circuits that formal compliance does not control.
• Keeler v. Comm'r, 243 F.3d 1212 (10th Cir. 2001): Quoted (via the government) for the notion that economic substance is a “cardinal rule” of federal tax law, supporting the majority’s view that Congress drafts against a backdrop of substance-based limits.

2. Supreme Court anchor: economic substance can defeat a transaction within statutory “terms”

• Gregory v. Helvering, 293 U.S. 465 (1935): The majority treated Gregory as decisive authority that even where a transaction satisfies Code “terms,” courts may deny the benefit if the arrangement is outside the statute’s intended scope. This supported the majority’s position that § 7701(o) is not a weak “interpretive aid,” but an operative limitation on tax benefits.

3. Persuasive circuit authority emphasizing “second look” review

• Bank of N.Y. Mellon Corp. v. Comm'r, 801 F.3d 104 (2d Cir. 2015): Used to support purposive, anti-formalist application—economic substance provides a “second look” and should not be “stym[ied]” by formal inclusion of conventional steps.
• Santander Holdings USA, Inc. v. United States, 844 F.3d 15 (1st Cir. 2016), Dow Chem. Co. v. United States, 435 F.3d 594 (6th Cir. 2006), and Coltec Indus., Inc. v. United States, 454 F.3d 1340 (Fed. Cir. 2006): Cited in the majority’s catalog of cases applying substance doctrines to deny claimed benefits arising from engineered transactions.

4. Waiver/forfeiture doctrine controlling the scope of review

• Richison v. Ernest Grp., Inc., 634 F.3d 1123 (10th Cir. 2011): The panel enforced adversarial-process limits: because LGI litigated only “relevance” below and admitted lack of substance for steps 1–3, it could not pivot on appeal to partial-benefit theories.

5. Standards of review

• Jewell v. United States, 749 F.3d 1295 (10th Cir. 2014) (summary judgment), Ausmus v. Perdue, 908 F.3d 1248 (10th Cir. 2018) (statutory construction), and Sala v. United States, 613 F.3d 1249 (10th Cir. 2010) (economic substance applicability): These framed the de novo posture that enabled the court to resolve the applicability question as a matter of law on undisputed facts/admissions.

6. The dissent’s contrary precedents (invoked to limit economic substance)

Judge Eid argued that § 7701(o) requires a distinct threshold “relevance” inquiry, relying on text-focused canons and cases emphasizing that courts should not render statutory language superfluous: Williams v. Taylor (quoting United States v. Menasche), Marx v. Gen. Rev. Corp., and Obduskey v. McCarthy & Holthus LLP.

On the merits, the dissent read economic substance as principally a tool for provisions that turn on “objective economic realities,” citing: Boulware v. United States, Knetch v. United States, Frank Lyon Co. v. United States, Cottage Savings Ass'n v. Comm'r, and other authorities (including Summa Holdings, Inc. v. Comm'r) to argue that Congress sometimes deliberately permits “form-driven” or tax-motivated elections. The majority addressed Summa Holdings only to distinguish it as involving a congressionally authorized, inherently tax-motivated regime (DISC), unlike TCJA international rules.

B. Legal Reasoning

1. “Relevance” under § 7701(o): the majority’s operative rule

Textually, the panel emphasized § 7701(o)(5)(A)’s definition: the doctrine “means the common law doctrine under which tax benefits ... are not allowable” if a transaction lacks economic substance or business purpose. The court also pointed to § 7701(o)(5)(C), which directs that “relevance” be determined as if § 7701(o) had never been enacted—i.e., by reference to the pre-codification common law. For the majority, that common law (including Gregory, Blum, and Sala) already allowed denial of benefits despite literal compliance.

2. Unit of analysis: “transaction” includes a series; Project Soy treated as one integrated plan

A decisive move was framing the “transaction” as the entire Project Soy series. The court relied on:

• 26 U.S.C. § 7701(o)(5)(D) (“The term ‘transaction’ includes a series of transactions.”), and
• Sala v. United States (requiring courts to determine which transactions control the inquiry).

On the undisputed record (including LGI’s admissions), steps 1–3 were executed over four days, integrated, and undertaken in contemplation of step 4. That integration prevented LGI from treating selected steps as categorically insulated.

3. No “basic business transaction” safe harbor for embedding conventional steps in a tax shelter

LGI argued that certain steps—e.g., § 351 corporate organization mechanics and entity-selection choices—are “basic business transactions” beyond § 7701(o). The court declined to decide whether any stand-alone category might ever be exempt, because—even accepting the legislative-history concept—Project Soy in aggregate was not “basic.”

The panel’s functional concern was administrability and anti-avoidance: if embedding routine elections or reorganizations could immunize an integrated shelter, sophisticated taxpayers could “inoculate” tax-avoidance schemes from economic substance scrutiny.

4. Disallowance mechanism in this case: disregarding steps 1–3 collapses the § 245A support

LGI conceded that steps 1–3 failed both prongs of § 7701(o)(1):

• no meaningful change in economic position (apart from federal income tax effects), and
• no substantial non-tax purpose.

Once those steps are disregarded, the “noneconomic” E&P they generated cannot support the claimed § 245A dividend-received deduction for the step 4 sale gain. The result is taxable gain on the sale.

5. The dissent’s competing statutory model (and why it matters)

The dissent viewed “relevance” as a gatekeeping inquiry preventing § 7701(o) from becoming a “free-floating override.” On that view, economic substance is relevant mainly when a benefit’s statutory trigger depends on economic reality (e.g., “interest,” “indebtedness,” “ownership,” “loss”), and not when the Code deliberately allows form-driven elections. The majority rejected the need to resolve a separate, formal “relevance” step in this case, characterizing the dispute as non-dispositive given the integrated shelter nature of Project Soy and the admitted lack of substance.

C. Impact

• International tax planning under the TCJA (GILTI/Subpart F/§ 245A): The decision signals that exploiting timing/attribution mismatches to transform gain into § 245A-deductible dividends via engineered E&P may be vulnerable to § 7701(o), even where literal requirements are met.
• Codification does not weaken the doctrine: The Tenth Circuit treats § 7701(o) as reaffirming the common law’s capacity to deny benefits notwithstanding formal compliance—important for disputes over “text vs. anti-abuse.”
• Series-of-transactions framing is central: Litigants should expect courts to select the “transaction” at the level of the integrated plan, especially when steps are executed rapidly and exist only to facilitate a tax result.
• Limits on “basic transaction” arguments: The presence of conventional steps (entity classification changes, reorganizations, capitalization moves) will not, without more, shield an overall shelter from § 7701(o).
• Litigation posture and admissions: The case underscores the practical power of admissions and issue-framing at summary judgment; waiver can be outcome-determinative in tax refund litigation.

IV. Complex Concepts Simplified

• Economic substance doctrine (§ 7701(o)): A transaction producing tax benefits may be disregarded if it (1) does not meaningfully change the taxpayer’s economic position (ignoring tax effects) and (2) lacks a substantial non-tax purpose.
• “Relevant” to a transaction: § 7701(o) applies only to transactions “to which the doctrine is relevant.” The majority treats relevance broadly in anti-shelter settings; the dissent treats it as a separate textual gatekeeper.
• § 245A deduction: Often called a “participation exemption,” it can allow a U.S. corporation to deduct certain foreign-source dividends from certain foreign subsidiaries, preventing double taxation on repatriation.
• GILTI / Subpart F / CFC: Anti-deferral regimes taxing U.S. shareholders currently on certain foreign earnings of “controlled foreign corporations.” Project Soy targeted a timing/ownership mismatch in when these rules bite.
• Earnings and profits (E&P): A tax accounting concept approximating a corporation’s ability to pay dividends; in Project Soy, E&P was engineered to support dividend characterization of sale gain.
• Step-transaction doctrine: A related anti-abuse doctrine that can collapse formally separate steps into one transaction if they are part of a prearranged plan. (Not decided by the majority here.)

V. Conclusion

Liberty Global, Inc. v. United States establishes (and forcefully reiterates within the Tenth Circuit) that the codified economic substance doctrine can apply to a tightly integrated, mechanically compliant TCJA “mismatch” plan designed to generate unintended benefits. The court treats the “transaction” as the full series and rejects attempts to avoid § 7701(o) by embedding routine corporate or entity-election steps within a broader shelter. The dissent highlights an enduring fault line—textual limits versus purposive anti-abuse enforcement—but the majority’s approach makes § 7701(o) a potent tool against sophisticated international tax engineering in the circuit.
