Thermal Circuits, Inc. v. Commissioner, T.C. Memo. 2026-29 (July 7, 2026)

In the complex intersection of supply chain financing and tax characterization, the distinction between a non-shareholder contribution to capital and compensation for services remains a frequent point of contention. A recent decision by the United States Tax Court in Thermal Circuits, Inc. v. Commissioner provides a critical examination of how manufacturing expansion agreements, specifically those involving leasehold improvements funded by a customer, are treated for federal income tax purposes.

Factual Background

The taxpayer, Thermal Circuits, Inc. ("Thermal"), is a C corporation that manufactures foil heating components. In 2016, Thermal's primary customer, Nicoventures Trading Limited ("NVT"), sought to significantly increase its order volume for these components. To meet this demand without increasing the per-unit cost, the parties negotiated an expansion of Thermal’s manufacturing capacity.

The parties eventually agreed that NVT would fund the expansion of Thermal’s leased manufacturing facility. NVT provided a total of approximately $4.3 million—$4.085 million in 2017 and $204,529 in 2018—to fund leasehold improvements. These improvements included additional manufacturing space, an etching room, a darkroom, and office space. Thermal did not report these funds as income on its 2017 or 2018 Form 1120, instead treating the payments as non-shareholder contributions to capital under Internal Revenue Code (I.R.C.) § 118(a). Furthermore, Thermal did not claim depreciation deductions for the portion of the leasehold improvements funded by NVT.

Taxpayer’s Position and Request for Relief

Thermal’s primary defense rested on the assertion that the funds provided by NVT were contributions to capital, which are excluded from gross income under I.R.C. § 118(a). Thermal contended that NVT intended to hold title to the improvements (the "facilities") even though Thermal held legal title as a matter of convenience. Consequently, Thermal argued that the funds were not taxable income and that the company was not liable for accuracy-related penalties under I.R.C. § 6662(a).

Judicial Analysis of Ownership and Gross Income

The threshold issue addressed by the Court was whether the leasehold additions belonged to Thermal or NVT. This determination was dispositive to the question of gross income. The Commissioner argued that Thermal owned the improvements, whereas Thermal argued that NVT held equitable title.

In evaluating ownership for tax purposes, the Court relied on the indicia of ownership established in Grodt & McKay Realty, Inc. v. Commissioner, 77 T.C. 1221 (1981). The Court noted that Thermal paid the insurance and property taxes for the entire premises, bore the attendant risks of possession, and held the certificate of occupancy in its name. Because Thermal failed to prove NVT owned the improvements, the Court held that the improvements belonged to Thermal.

Under I.R.C. § 61(a), which defines gross income as "all income from whatever source derived," the Court determined that the receipt of the $4.3 million improvement was an accession to wealth. The Court emphasized that "gross income is construed broadly to include all 'accessions to wealth, clearly realized, and over which the taxpayers have complete dominion'" (Commissioner v. Glenshaw Glass Co., 348 U.S. 426, 431 (1955)). Consequently, the receipt of the funds constituted taxable income.

Application of Section 118 and the Compensation Doctrine

The crux of the litigation involved whether the funds qualified for exclusion under I.R.C. § 118(a). To determine if a transfer is a contribution to capital, the Court applied the five-part test derived from United States v. Chicago, Burlington, & Quincy Railroad Co., 412 U.S. 401 (1973): (1) whether the contribution becomes part of the transferee’s permanent working capital structure; (2) whether the contribution is not compensation for specific, quantifiable services; (3) whether the contribution is bargained for; (4) whether the contribution results in a benefit commensurate with its value; and (5) whether the contribution contributes to the production of additional income.

While the funds met several criteria, the Court found they failed the second prong. The evidence suggested that NVT’s primary objective was to secure more foil heaters at a lower per-unit cost. NVT had performed a cost-benefit analysis and determined that the investment would be recouped after purchasing a specific quantity of heaters. The Court noted, "Because NVT sought to obtain more foil heaters at a lower price, we hold that the $4.3 million it paid is compensation to Thermal."

Furthermore, even if the funds were considered a contribution to capital, they would be disqualified under the exceptions in I.R.C. § 118(b). Specifically, § 118(b)(1) excludes contributions made by "a customer or potential customer" or those made "in aid of construction." The Court held that the funds were both, thereby requiring their inclusion in gross income.

Timing of Income Recognition

For taxpayers utilizing the accrual method, income is includible when "all the events have occurred which fix the right to receive such income and the amount thereof can be determined with reasonable accuracy" (Treas. Reg. § 1.451-1(a)). Following this rule, the Court determined that the $4.085 million received in 2017 must be included in 2017 income, and the $204,529 received in 2018 must be included in 2018 income.

Reasonable Cause and the Accuracy-Related Penalty

The final issue was whether Thermal was liable for a 20% accuracy-related penalty under I.R.C. § 6662(a). Thermal raised the defense of reasonable cause and good faith under I.R.C. § 6664(c).

The Court examined whether Thermal exercised "ordinary business care and prudence" (Neonatology Assocs., P.A. v. Commissioner, 115 T.C. 43 (2000)). The Court found that Thermal’s mistake of fact regarding ownership was reasonable under the circumstances. The "Draft Framework Agreement" used the term "facilities" within the definition of "NVT Property," which Thermal interpreted to include the leasehold improvements. Additionally, the "HoT Agreement" allowed NVT to assert control over "Dedicated Equipment," which included "premises."

The Court observed that Thermal’s conduct—such as using the facility only for NVT, attempting to get a release to use the space, and refraining from claiming depreciation—evidenced an honest intent. The Court concluded: "This pattern evinces an honest, though mistaken, belief that NVT owned the leasehold addition. Accordingly, we conclude that Thermal had reasonable cause and acted in good faith such that it is not liable for the accuracy-related penalty."

Conclusion

The Court ruled that Thermal must include the $4.3 million in gross income for the 2017 and 2018 tax years. However, due to the taxpayer's reasonable, albeit mistaken, reliance on the contractual language regarding ownership, the accuracy-related penalty was vacated.
