Background
Liberty Global, Inc. (LGI) executed a four-step plan called Project Soy in a four-day window in December 2018. Project Soy was intended to exploit what its advisors described as a ‘last day of year rule/mismatch’ in the Code between the global intangible low-taxed income (GILTI) and subpart F regimes on one hand and the section 245A dividends-received deduction on the other. The plan manufactured earnings and profits inside a controlled foreign corporation (CFC) through intercompany steps, then used that CFC’s earnings to recharacterize an approximately $2.4 billion intra-group stock transfer as a section 245A-eligible dividend, supporting a refund claim of roughly $110 million. LGI conceded that the first three steps failed both prongs of the codified economic substance test. The only contested questions were whether section 7701(o) was ‘relevant’ to Project Soy at all, and if so, at what level of aggregation.
Mechanical Code compliance is not a shield
Section 7701(o)(5)(A) defines the codified doctrine as ‘the common law doctrine under which tax benefits . . . are not allowable if the transaction does not have economic substance or lacks a business purpose.’ Relying on Gregory v. Helvering, 293 U.S. 465 (1935), and its own prior decisions in Sala v. United States, 613 F.3d 1249 (10th Cir. 2010), and Blum v. Commissioner, 737 F.3d 1303 (10th Cir. 2013), the court held that a transaction that follows the literal words of the Code can still fail the doctrine. The Tenth Circuit is now aligned with the First, Second, Sixth and Federal Circuits on this point.
No categorical exemption for basic business transactions
LGI argued that section 351 contributions and entity classification elections are, by their character, outside the doctrine. The court rejected the premise. Section 7701(o) contains no express exemptions, and references in the legislative history to ‘basic business transactions’ are illustrations, not carve-outs. The court did not decide whether any specific transaction type, standing alone, might fall outside the doctrine, but made clear that integrating routine mechanics into a tax-motivated plan does not insulate the plan.
The integrated transaction controls
Section 7701(o)(5)(D) defines ‘transaction’ to include ‘a series of transactions.’ Applying Sala, the Tenth Circuit treated Project Soy’s four steps, executed in a compressed period to achieve a unified tax objective, as a single transaction for economic substance purposes. The court also distinguished Summa Holdings, Inc. v. Commissioner, 848 F.3d 779 (6th Cir. 2017), on the ground that Summa Holdings involved a regime in which Congress explicitly authorized transactions without economic substance to deliver a defined benefit. The Tenth Circuit noted nothing comparable exists in the Tax Cuts and Jobs Act (TCJA) international provisions.
M&A planning going forward
Interaction-driven planning faces sharply elevated risk
Any M&A structure whose tax benefit depends on the interaction of two or more Code provisions (i.e., a timing window between anti-deferral and participation-exemption regimes, an effective-date mismatch, a gap between statutory and regulatory mechanics) should be evaluated against the purpose of each provision being relied on. If the resulting benefit cannot be reconciled with congressional intent, mechanical compliance will not save it. This is particularly acute for post-TCJA international planning involving section 245A, GILTI, subpart F, previously taxed earnings and profits ordering, section 954(c)(6), the high-tax exclusion and section 367 mechanics.
Pre-closing reorganizations and post-acquisition integration require a fresh look
Buy-side and sell-side structuring routinely relies on tightly choreographed pre-closing restructurings and post-closing integration steps (such as check-the-box elections, section 351 drops, F reorganizations, cash-D reorganizations) to produce a targeted basis, attribute or withholding result. After Liberty Global, each element of the sequence should be defensible on its own non-tax merits, or the sequence as a whole should be. Deal teams should resist structuring that groups otherwise independent steps into a compressed window solely for tax reasons.
Benefit-harvesting is exposed
Plans designed primarily to extract a U.S. tax benefit (for example, generating or accelerating a deduction, recharacterizing income into a preferred category, moving earnings into a vehicle eligible for a specific exclusion) are now squarely in the line of fire in the Tenth Circuit and in line with existing circuit authority elsewhere. This does not mean such planning is foreclosed, but it does mean the non-tax economic story must be real, measurable and contemporaneously documented.
Documentation is non-negotiable
The Project Soy record featured internal communications and advisor work product framing the plan around the targeted tax mismatch. Contemporaneous descriptions that characterize a transaction primarily by the tax benefit it produces will be difficult to reconcile with a later assertion of substantial non-tax purpose. Board materials, steering committee decks, engagement letters, tax memos, diligence reports and day-to-day email traffic should reflect the business rationale the taxpayer will rely on if the transaction is challenged. Naming conventions and project code names that signal the tax objective invite litigation trouble.
Opinion and diligence practice will need to adapt
Comfort opinions supporting integrated structures should engage section 7701(o) head-on, address the integrated-transaction unit of analysis and measure the plan against the policy of the benefit provision relied on. Tax diligence on target structures, particularly private equity add-on transactions executed close to year-end or statutory effective-date boundaries, should flag prior integrated restructurings as potential exposure items. Financial statement reserves and uncertain tax position disclosures should reflect the sharpened doctrine after Liberty Global.
Penalty exposure is material and largely undefeatable
Section 6662(b)(6) imposes a 20% accuracy-related penalty (40% under section 6662(i) for undisclosed transactions) on any underpayment attributable to a transaction lacking economic substance under section 7701(o). The reasonable-cause defense is not available for that component. An economic substance loss therefore arrives with a penalty that cannot be argued away by reliance on counsel’s opinion. With the Tenth Circuit now squarely aligned with its sister circuits, the settled cost of losing an economic substance challenge has grown.
