Executive Summary

Transactions that lack economic substance can be disregarded or recast by the IRS. Congress codified the test for economic substance in 2010 to make the test’s elements uniform. The Tax Court recently concluded in Patel v. Commissioner 1 that the economic substance test applies only where the economic substance analysis is relevant under criteria applied in federal tax case law. The Tax Court’s Patel decision gives effect to the relevancy requirement Congress placed in the Tax Code.2 This decision conflicts with the conclusion of the District Court of Colorado in Liberty Global Inc. v. United States.3

The Tax Court also held that the economic substance test was relevant to the taxpayer’s captive insurance transaction, based on historical federal tax case law.


165 T.C. No. 10 (2025).
Section 7701(o)(1). Unless otherwise stated or clear from the context, all reference to “section” in this memorandum are to the Internal Revenue Code of 1986 (the Code), as amended, and all reference to “Reg. section” are to the regulations promulgated under the Code.
No. 1:20-cv-03501-RBJ (D. Colo. Oct. 31, 2023).

Patel’s captive insurance tax goals

Sunil Patel, a Texas physician and entrepreneur, operated several medical and research businesses. He established two captive insurance companies (Captives) to provide insurance coverage to his businesses. The Captives’ arrangements were intended to achieve these federal income tax results:

  1. Premiums paid to the Captives would be tax deductible under section 162, and

  2. The Captives’ insurance income would be tax exempt under section 831(b) (they would be taxed only on their investment income).

The Tax Court held that the Captives did not achieve these results because the captive insurance arrangements lacked economic substance. The court upheld both the income tax liability assessed by the IRS, and accuracy-related and noneconomic substance-related penalties.

The relevancy threshold for economic substance analysis

The central issue in Patel was whether the economic substance doctrine, as codified in section 7701(o), requires a threshold determination of “relevance” before applying the economic substance test. The Code states that the doctrine applies “in the case of any transaction to which the economic substance doctrine is relevant,” and section 7701(o)(5)(c) indicates that relevancy is determined “in the same manner as if this subsection had never been enacted.” The Tax Court concluded that this language requires courts to first decide, as a matter of law, whether the doctrine is relevant to the transaction, referencing both the statutory text and legislative history.4

The government’s position was that a relevancy inquiry is not separate from the substantive two-pronged economic substance test. The Tax Court disagreed, concluding that courts should look at prior court decisions in applying the threshold relevancy inquiry.

Applying the threshold inquiry, the court found the economic substance doctrine relevant to Patel’s microcaptive insurance arrangement. It looked to federal tax law addressing insurance transactions. For example, the Sixth Circuit Court of Appeals’ decision in Malone & Hyde5 was an instance in which the courts applied the economic substance doctrine to deny deductions for payments to a sham insurance captive. The court reasoned that, because the deductibility of insurance premiums under section 162 depends on whether the arrangement is bona fide insurance with real risk shifting and business purpose, the economic substance doctrine is relevant when the facts suggest the arrangement may be a sham or lack business purpose.

The economic substance test

If economic substance is relevant to a transaction’s tax treatment, it must satisfy a two-part test. For the transaction’s asserted tax results to stand, the transaction must have (a) a meaningful change in economic position apart from tax effects, and (b) a substantial non-tax purpose.6

In Patel’s case, the court found that the microcaptive arrangement failed both prongs of the economic substance test: there was no meaningful change in economic position apart from tax effects (due to the circular flow of funds and excessive, non-actuarial premiums), and there was no substantial non-tax purpose (as the arrangement was motivated solely by tax avoidance, with no genuine insurance need).

Conclusion and implications for tax planning

The Tax Court’s decision in Patel concluded that the two-pronged economic substance test applies to a transaction only after a threshold relevancy determination. The decision conflicts with the conclusion of the District Court of Colorado in Liberty Global Inc. v. United States,7 which rejected a threshold relevancy inquiry in applying section 7701(o) in assessing a transaction involving the dividends received deduction under section 245A. The court found that the economic substance doctrine was relevant to Patel’s Captives and upheld the IRS tax assessment.

In the broader context of tax planning (including but not limited to mergers and acquisitions), the Patel decision underscores the need to consider whether economic substance is relevant under tax case law. In the narrower context of captive insurance arrangements, taxpayers utilizing those arrangements should consider the potential effects of the Patel decision’s economic substance analysis on their tax positions.
