Cleveland v. Commissioner

The legal framework governing the research and development (R&D) tax credit in the United States has undergone a profound transformation, moving from the foundational "trade or business" interpretations of the mid-twentieth century to the hyper-technical documentation requirements of the current era. Central to this evolution is the landmark decision in Cleveland v. Commissioner, which initially helped define the boundaries of Section 174 expenditures, and the subsequent 2023-2024 judicial rulings that have significantly heightened the evidentiary burden on taxpayers. Understanding the implications of these developments requires a comprehensive examination of the statutory interplay between Section 41 and Section 174, the rigorous application of the four-part test, and the shift in the Internal Revenue Service's (IRS) enforcement strategy toward objective, contemporaneous substantiation.

The Jurisprudential Foundations of Section 174 and the Cleveland Precedent

The ability to claim an R&D tax credit under Section 41 is predicated on the underlying costs qualifying as research and experimental expenditures under Section 174. Historically, Section 174 was designed to provide a broad incentive for innovation by allowing for the immediate deduction of research costs, thereby avoiding the complexities of capitalization. The early case of Cleveland v. Commissioner, 297 F.2d 169 (4th Cir. 1961), remains a critical reference point for determining whether expenditures are made "in connection with" a taxpayer's trade or business, a prerequisite for both the deduction and the credit.

The Factual Context of Cleveland v. Commissioner

The dispute in Cleveland v. Commissioner centered on Richard F. Cleveland, a business advisor and attorney who entered into an informal, and later formal, joint venture with an inventor named Kerla. Kerla had developed an inorganic liquid binding material, termed "Kerloid," and was seeking to perfect its commercial applications. Cleveland provided the necessary funding for laboratory facilities and experimentation, while Kerla provided the technical expertise. The IRS initially challenged Cleveland’s deductions, arguing that the funds provided were loans rather than business expenses and that Cleveland was not personally engaged in the "trade or business" of inventing.

The Tax Court initially sided with the Commissioner, finding that Cleveland's role was primarily financial and that no joint venture existed prior to a written agreement in 1954. However, the Fourth Circuit reversed this in part, establishing that the existence of a joint venture, even if one party's contribution is primarily financial and managerial, can satisfy the "trade or business" requirement for Section 174 purposes. This ruling affirmed that the "in connection with" standard of Section 174 is broader than the "carrying on" standard of Section 162, which governs general business expenses.

Impact on the Scope of Research and Development

The Cleveland decision provided a vital precedent for investors and small businesses, suggesting that active participation in a venture aimed at developing a new product is sufficient to claim research deductions, even if the business has not yet reached the stage of selling goods or services. This was later expanded by the Supreme Court in Snow v. Commissioner, which further loosened the trade or business requirement for pre-operational entities. The legacy of Cleveland v. Commissioner thus established a pro-innovation bias in the tax code, one that sought to encourage the acquisition of information to eliminate technical uncertainty regardless of the taxpayer's current revenue status.

The Modern Regulatory Environment and the Four-Part Test

While Cleveland and its progeny defined the entry points for Section 174, modern taxpayers must navigate the more restrictive "Four-Part Test" established under Section 41(d) to claim the research credit. This test requires that the research activity be undertaken for a qualified purpose, be technological in nature, involve the elimination of uncertainty, and fundamentally consist of a process of experimentation.

The Section 174 Uncertainty Test

The first prong of the credit eligibility framework is the Section 174 Test, which necessitates that the research be conducted to discover information that would eliminate uncertainty concerning the development or improvement of a business component. Uncertainty exists if the information available to the taxpayer does not establish the capability or method for developing or improving the component, or the appropriate design of the component.

In recent years, the courts have refined what constitutes "available information." In Phoenix Design Group, Inc. v. Commissioner (2024), the Tax Court emphasized that the mere existence of design iterations does not prove technical uncertainty. If a taxpayer already possesses the data and the engineering principles required to resolve a design challenge through standard calculations, then no true technical uncertainty exists for the purposes of the credit. This creates a high hurdle for professional service firms, such as engineering and architectural offices, which may engage in complex work that nevertheless relies on established professional standards.

The Technological in Nature Requirement

The second prong requires that the research rely on the "principles of physical or biological sciences, engineering, or computer science". This requirement distinguishes qualified research from activities based on the social sciences, arts, or humanities. While many engineering projects are intrinsically technological, recent case law like Phoenix Design Group suggests that if the work involves routine application of engineering principles—such as standard MEPF (mechanical, electrical, plumbing, and fire protection) design—it may fail this test if the taxpayer cannot document how they moved beyond conventional knowledge to solve a specific problem.

The Business Component Test

The third prong mandates that the research be intended to be useful in the development of a new or improved business component of the taxpayer. A business component can be a product, process, computer software, technique, formula, or invention to be held for sale, lease, or license, or used by the taxpayer in its own trade or business. Taxpayers often stumble here by defining their business component too broadly—for example, treating an entire building or a complex ship as a single component rather than breaking it down into sub-components where actual innovation occurred.

The Process of Experimentation and the 80% Threshold

The most significant battleground in contemporary R&D tax litigation is the Process of Experimentation (POE) test. To satisfy this fourth prong, substantially all of the research activities must constitute elements of a process of experimentation. The "substantially all" requirement is defined by the 80% rule: at least 80% of the activities, measured by cost or time, must relate to a process designed to evaluate one or more alternatives to achieve a result where the capability, method, or design is uncertain.

Analyzing Little Sandy Coal, Inc. v. Commissioner

The 2023 decision in Little Sandy Coal, Inc. v. Commissioner (7th Circuit) represents a watershed moment for the 80% rule. The taxpayer, a shipbuilder, claimed credits for the development of novel barges and tankers. The court disallowed the credits because the taxpayer could not prove that 80% of the total activities related to the process of experimentation. The Seventh Circuit rejected the "taking it on faith" approach, stating that the burden lies with the taxpayer to document that activities were elements of experimentation rather than mere production or routine design.

This case introduced a rigorous numerator-denominator framework for the 80% test:

• Numerator: Activities that constitute elements of a process of experimentation for a qualified purpose.
• Denominator: All research activities that are not excluded under Section 41(d)(4) and whose expenses are deductible under Section 174.

The court emphasized that "just because a pilot model is being developed, it does not mean all activities in its development constitute experimentation". This distinction is critical for manufacturing and construction firms that often conflate the novelty of the final product with the nature of the work performed by every employee on the project.

The Shrinking-Back Rule

When a taxpayer fails the 80% test at the level of the primary business component (e.g., the whole ship), the "shrinking-back" rule may allow them to apply the test to a smaller sub-component (e.g., a novel hull design or a new propulsion system). However, this requires specific, activity-level documentation for that sub-component. If the taxpayer’s records do not distinguish between the time spent on the novel hull and the time spent on the routine deck assembly, the shrinking-back rule cannot be successfully invoked.

The Crisis of Substantiation: Moore v. Commissioner and Executive Compensation

A recurrent theme in the "losing streak" of R&D cases is the failure to substantiate the qualified services of high-level personnel. Section 41(b)(2)(B) allows for the inclusion of wages for individuals who are:

• Engaged in the actual conduct of qualified research.
• Engaged in the direct supervision of qualified research.
• Engaged in the direct support of qualified research.

The "One-Up" Rule for Supervision

In Moore v. Commissioner (2023), the Tax Court challenged the inclusion of 65% of the COO's wages as QREs. The court found that the COO was "two layers removed" from the direct R&D activities and thus did not meet the "one-up" requirement for direct supervision. Direct supervision requires immediate supervision of those performing the research, not the management of managers.

Furthermore, the Moore case highlighted the danger of using high-level estimates. The court noted that "the record provides no estimate of the time spent on qualified research as distinguished from the broader category of new product development". This suggests that for highly compensated individuals, the IRS now expects a level of specificity that can only be provided by contemporaneous time-tracking or highly detailed project logs that map individual activities to specific technical uncertainties.

The 80% Wage Rule for Individuals

The "substantially all" test also applies at the individual level. If 80% or more of an employee's time is spent on qualified activities, 100% of their wages may be included. If the percentage falls below 80%, only the actual qualified portion is included. The lack of time-tracking systems often forces taxpayers to rely on post-hoc estimates, which the courts in Little Sandy Coal and Moore have largely rejected as "faith-based" rather than "sight-based" evidence.

Funded Research and the Allocation of Intellectual Property Rights

A major exclusion under Section 41(d)(4)(H) is research that is "funded" by another party. To claim the credit, a taxpayer must prove that they are not performing research on behalf of a client who bears the financial risk and retains the results.

The Economic Risk and Substantial Rights Tests

The determination of whether research is funded hinges on two criteria:

• Economic Risk: Payment for the research must be contingent on its success. If a taxpayer is entitled to payment regardless of the outcome (e.g., time-and-materials), the research is funded and ineligible for the credit.
• Substantial Rights: The taxpayer must retain substantial rights in the research results. If the client retains exclusive rights and the taxpayer retains only "incidental benefits" or "institutional knowledge," the research is considered funded.

In the recent case of System Technologies, Inc. v. Commissioner (2025), the Tax Court provided a glimmer of hope for taxpayers, ruling that summary judgment for the IRS was inappropriate because the scope of "contingent on success" can be influenced by state law. For example, if state law provides the buyer a remedy (such as a refund) in the event of a total failure of the research, the taxpayer may be considered to have retained the economic risk even if the contract does not use the word "contingent".

The Role of Architectural and Engineering Contracts

The case of AS+GG v. Commissioner further clarified that payment based on "design milestones" might implicitly imply that payment is contingent on the success of the research. Similarly, the retention of copyright—even if a license is granted to the client—can be evidence of substantial rights. These nuances suggest that for future R&D applications, the language of the underlying services agreement is as important as the technical nature of the work itself.

Legislative and Administrative Shifts: Section 174 Amortization

The landscape of innovation incentives was radically altered by the Tax Cuts and Jobs Act (TCJA) of 2017. Effective for tax years beginning after December 31, 2021, Section 174 was modified to require the capitalization and amortization of research and experimental expenditures.

The End of Immediate Expensing

Taxpayers must now amortize domestic research costs over a five-year period and foreign research costs over a fifteen-year period. This change has significant implications for the Section 41 credit, as the credit is only available for expenses that are deductible (or would be deductible but for the capitalization rule) under Section 174. This creates a "double-edged sword": taxpayers must identify all Section 174 costs for amortization purposes (which may include a broad range of development costs) while simultaneously proving a subset of those costs meet the much stricter "four-part test" for the Section 41 credit.

Pending Legislative Relief: H.R. 1 and Section 174A

There is ongoing legislative effort to reinstate immediate expensing for domestic R&D. H.R. 1 proposes the creation of a new Section 174A, which would return to the full deductibility of domestic research costs in the year incurred. The proposed transition rules would allow taxpayers to catch up on unamortized domestic costs from the 2022-2024 period. However, until such legislation is signed into law, taxpayers must comply with the capitalization requirements and file necessary accounting method changes using Form 3115.

The IRS "Five Items" Guidance and Refund Claim Scrutiny

In response to the perceived over-claiming of R&D credits, particularly through "study-based" refund claims, the IRS issued new procedural requirements in October 2021. For a refund claim based on the research credit to be considered valid, it must include five essential pieces of information at the time of filing.

The Requirements for a Valid Refund Claim

• Business Component Identification: The taxpayer must list all business components that form the basis for the credit.
• Activity Description: For each business component, a description of the research activities performed is required.
• Personnel Listing: A list of individuals who performed each activity (though this requirement was relaxed for claims post-June 18, 2024).
• Information Sought: The specific technical information each individual sought to discover (also relaxed post-June 2024).
• Cost Detail: The total qualified employee wage, supply, and contract expenses related to the activities.

The IRS provided a "perfection period" (extended through January 10, 2025) that allows taxpayers 45 days to provide missing information before a claim is officially rejected. However, the IRS has emphasized that repeating legal definitions or statutory language is insufficient; the response must be factually specific to the taxpayer's projects.

The Shift to "Walking by Sight"

The combined effect of cases like Little Sandy Coal and the IRS guidance is a shift toward an "activity-based" rather than an "expense-based" audit model. In the past, many taxpayers calculated their credit by pulling general ledger accounts and applying broad percentages. Under the new regime, the IRS and the courts require a direct link between the employee’s daily work and the specific technical uncertainty being resolved.

State-Level Implications: The Ohio R&D Investment Tax Credit

The federal evolution of the R&D credit has direct parallels at the state level, particularly in Ohio, which is home to some of the most advanced technological institutions and industries in the country. Ohio’s Research and Development Investment Tax Credit is a nonrefundable credit designed to encourage corporations to invest in R&D activities within the state.

Mechanics of the Ohio Credit

The Ohio credit, authorized by Code Section 5751.51, is generally equal to 7% of the amount of qualified research expenses incurred in Ohio that exceed the taxpayer's average investment over the preceding three taxable years. Key features include:

• Applicability: The credit is used to offset Commercial Activity Tax (CAT) liability.
• Nexus: All R&D activities must be conducted within the state of Ohio to qualify.
• Carry-forward: Unused credits can be carried forward for up to seven years.
• Federal Alignment: Ohio largely follows the federal definition of "qualified research" under Section 41, meaning that federal case law developments like Phoenix Design Group and Little Sandy Coal will likely influence state-level audits in Ohio.

Audit Trends in Ohio

The Ohio Department of Taxation advises that taxpayers retain detailed records for the current and three preceding taxable years to substantiate their claims. Common audit issues in Ohio include the "sourcing" of sales and the determination of whether receipts qualify as "gross receipts" for the CAT base. As the IRS tightens its documentation standards, it is expected that state taxing authorities will follow suit, placing a higher premium on contemporaneous project records that distinguish between general engineering and qualified R&D.

Implications for Future R&D Tax Credit Applications

The transition from the foundational jurisprudence of Cleveland v. Commissioner to the rigorous modern standards of Phoenix Design Group has created a new operational reality for taxpayers. Success in future R&D credit applications will depend on a proactive approach to documentation, contractual clarity, and technical specificity.

Redefining Technical Uncertainty in Professional Services

For engineering and design firms, the most critical lesson from Phoenix Design Group is that complexity does not equal uncertainty. Future applications must clearly articulate the "technical gap": the specific reason why existing engineering standards and basic calculations were insufficient to achieve the desired result. This requires documenting the "failed" alternatives—the models that didn't work and the designs that were rejected—as evidence of a true process of experimentation.

Strategic Use of the Shrinking-Back Rule

Taxpayers should adopt a "bottom-up" documentation strategy. Rather than attempting to prove that 80% of an entire project was experimental, they should identify discrete sub-components where the technical uncertainty was most acute. By focusing documentation on these "high-innovation" areas, taxpayers can satisfy the 80% rule for the sub-component even if the larger project is dominated by routine production and design adaptation.

Contractual Protection Against "Funded" Disallowance

Given the Tax Court’s focus on economic risk and substantial rights, businesses engaged in contract research must ensure their agreements are "R&D-friendly". This includes:

• Defining Success: Explicitly linking payment to the successful completion of technical milestones rather than mere time spent.
• Rights Retention: Ensuring the taxpayer retains the right to use the research results, even if the client receives a broad license or ownership of specific deliverables.
• Warranty Clauses: Understanding how state-level warranty and breach-of-contract laws might inadvertently shift economic risk back to the researcher, as seen in the System Technologies analysis.

Moving Beyond High-Level Estimates

The "losing streak" in the Tax Court serves as a stark reminder that oral testimony and post-hoc estimates are no longer sufficient to carry the burden of proof. Companies must transition to contemporaneous time-tracking systems that categorize labor at the project and activity level. For highly compensated executives, this documentation is even more critical, as the IRS will almost certainly challenge claims of "direct supervision" that are not backed by specific, "one-up" evidence of technical involvement.

Conclusion

The legal trajectory of the R&D tax credit has moved from the broad, policy-driven incentives seen in the Cleveland v. Commissioner era toward a hyper-technical, evidence-based regime. The recent judicial focus on the 80% rule, the objective nature of technical uncertainty, and the requirement for contemporaneous documentation has placed a significant burden on taxpayers. However, by understanding these legal precedents and aligning their internal processes with the new "sight-based" standard of proof, innovative companies can still successfully navigate the complexities of Section 41. The future of R&D tax incentives will be defined not by the novelty of the final product, but by the ability of the taxpayer to document the journey of experimentation that led to it. In an environment of increased scrutiny and legislative shifts, the only defense against a "faith-based" disallowance is a robust, fact-based narrative of discovery.
