The Statutory Foundation: Sections 41, 174, and 174A

For the historical tax years discussed in these cases, Section 41(d)(1)(A) referred to expenditures eligible for treatment under Section 174. Following Public Law 119-21, current Section 41(d)(1)(A) refers to domestic research or experimental expenditures under Section 174A. Section 174A generally permits immediate deduction of domestic research expenditures paid or incurred in tax years beginning after December 31, 2024, with an optional capitalization election and separate transition rules. Foreign research expenditures remain subject to Section 174 amortization. Deduction treatment alone does not establish credit eligibility: the other Section 41 requirements and exclusions must also be satisfied.

Gardner, T.C. Memo. 2011-137, illustrates the separate capitalization rules for land development. The court required capitalization of engineering costs and taxes associated with a 34-acre parcel held for production. It did not decide whether those costs qualified for a research credit or establish that engineering undertaken for a commercial project is necessarily ineligible research.

The Gardner v. Commissioner (2011) Decision: A Case Study in Capitalization

Judge Halpern considered a contractor’s real-estate activities, including the development of land for subdivision. Section 263A required capitalization of the relevant preproduction engineering costs and taxes. Interest received different treatment because physical production had not begun during the year at issue. The decision also addressed the character of gain from separate property sales. These distinctions matter: the opinion cannot accurately be presented as a blanket denial of engineering deductions, much less a denial of R&D credits.

The practical lesson is to identify what an expenditure actually paid for and apply the governing provision. The fact that a project will produce something for sale does not itself prevent qualifying research during development. Union Carbide Corp. v. Commissioner, T.C. Memo. 2009-50, affirmed at 697 F.3d 104 (2d Cir. 2012), separately addressed research-credit supply expenses in commercial production trials. Its treatment of ordinary production inputs should not be converted into an industry-wide prohibition on research involving saleable products.

The Evolution of the Simplified Credit

The Alternative Simplified Credit (ASC), under Section 41(c)(5), uses a three-year QRE comparison instead of the regular credit’s historical fixed-base calculation. It does not change which activities or costs qualify and does not cure a capitalization or substantiation defect. The applicable calculation depends on the taxpayer’s QRE history and valid election.

These formulas describe the principal QRE-based components before applicable elections, limitations, aggregation rules, and Section 280C coordination.

The Funded Research Doctrine: Risk, Rights, and Recent Developments

Section 41(d)(4)(H) excludes research to the extent funded by another person or governmental entity. Treasury Regulation § 1.41-4A(d), incorporated through § 1.41-4(c)(9), examines payment contingency and retained substantial rights. Payments contingent on successful research generally are not funding under this rule. If the researcher retains no substantial rights, the research is fully funded for credit purposes; where rights are retained, funding may reduce rather than eliminate otherwise eligible expenses. All relevant agreements must be considered.

Gardner v. Commissioner, 845 F.3d 971 (9th Cir. 2017), involved taxable receipts associated with ministry activities and asserted vows of poverty. Its discussion of control over bank accounts concerns income inclusion. It did not establish the research-credit substantial-rights test. For Section 41, exclusive ownership of intellectual property is not invariably required: enforceable rights to use research results can be substantial, while incidental experience alone may be insufficient. Those questions must be evaluated under the research-credit rules and the actual agreements.

Smith and System Technologies: Procedural Rulings and the Later Smith Opinion

The Smith summary-judgment order was issued on December 18, 2024, and the System Technologies order on January 3, 2025. Both denied IRS motions, but neither should be described as an unconditional award of all claimed credits. A denial of summary judgment can leave factual or legal issues for later resolution. These orders did not displace the statutory research requirements.

In the preliminary Smith proceedings, the court found that unresolved questions concerning contracts governed by foreign law prevented summary judgment. In its later opinion, Smith v. Commissioner, T.C. Memo. 2026-50, the court found that payments under the six sample contracts were not contingent on research success. Four projects nevertheless satisfied the substantial-rights requirement, allowing otherwise qualifying expenses to remain eligible to the extent they exceeded allocable funding. The other two did not satisfy that requirement. The later outcome limits the significance of the earlier procedural victory.

In System Technologies, Inc. v. Commissioner, Docket No. 12211-21, the court considered Indiana law and the remedies available if the contractor failed to deliver. The warranty terms did not eliminate remedies for total breach, including repayment. That analysis supported denial of the IRS’s partial-summary-judgment motion on funding. The lesson is to examine the legal effect of the entire agreement; a warranty or fixed-price label alone does not establish credit eligibility.

The Process of Experimentation and the Four-Part Test

Gardner (2011) did not decide the process-of-experimentation test. The relevant standard comes from Section 41(d) and Treasury Regulation § 1.41-4. The analysis identifies a business component, the technical uncertainty at the outset, alternatives intended to resolve it, and an evaluative process such as modeling, simulation, or systematic trial and error. Under the regulation, at least 80% of the relevant research activities, measured on a cost or other consistently applied reasonable basis, must constitute elements of experimentation for a qualified purpose.

Design revisions and calculations do not automatically demonstrate experimentation, but using established engineering principles does not automatically defeat a claim. The regulations expressly allow existing technologies and scientific principles. Project evidence should explain what remained uncertain, which alternatives were evaluated, and how the results informed the design.

Identifying Uncertainty in Design and Engineering

Relevant uncertainty concerns capability, method, or appropriate design—not necessarily the theoretically optimal design. Qualifying purposes include improvements in function, performance, reliability, or quality. A trade-secret dispute involving Gardner Denver and the independent economic value of meeting templates does not establish an R&D credit test. Management studies, efficiency surveys, and research directed solely at style or cosmetic factors must be assessed against Section 41’s express exclusions rather than unrelated intellectual-property standards.

Procedural Implications and the Burden of Production

The Gardner income-tax proceedings offer general procedural lessons, but they do not create special rules for substantiating R&D credits. The Beard test for a valid return requires sufficient data to calculate tax, a document purporting to be a return, an honest and reasonable effort to comply with tax law, and a signature under penalties of perjury. Meeting those requirements does not by itself establish entitlement to a credit.

In Gardner v. Commissioner, T.C. Memo. 2013-67, the IRS did not establish valid substitutes for returns for purposes of the Section 6651(a)(2) failure-to-pay addition to tax. Account transcripts alone did not meet its burden of production on that issue. This limited penalty ruling should not be generalized into a requirement that the IRS prove the absence of qualified research before disallowing a credit. Credit claimants ordinarily must substantiate entitlement, subject to applicable burden-shifting and procedural rules.

Section 6700 Penalties and Abusive Shelters

Gardner v. Commissioner, 145 T.C. 161 (2015), concerned Section 6700 promoter penalties arising from a corporation-sole arrangement. It was not an R&D-credit case. Section 6700 addresses specified conduct in organizing or selling arrangements, including material false or fraudulent tax-benefit statements made with the requisite knowledge and specified valuation overstatements. Its penalties are tied to statutory conduct and calculations, not simply annual income-tax deficiencies. Applying it to any research-credit adviser requires proof of the relevant statutory elements; an unsuccessful claim alone does not establish promoter liability.

Strategic Documentation and the Classification of Costs

Gardner and Union Carbide do not establish a universal “primary purpose” test for all research-credit claims. A sound claim separately evaluates the research activities, eligible cost categories, exclusions, and funding. Records should connect each claimed amount with work that meets the applicable requirements, distinguishing research expenditures from ordinary production and indirect expenses.

• Direct Research Costs: Potentially eligible categories include wages for qualified services, qualifying supplies used in research, and the permitted portion of contract research expenses. Technical uncertainty alone does not make every associated cost eligible.
• Indirect Research Costs: General overhead and ordinary maintenance do not become QREs merely because research occurs at the same facility. Specialized rules may apply to particular expenses, so category-specific analysis is necessary.
• Production Costs: Ordinary production and development costs may require capitalization under the applicable provisions. A commercial setting does not automatically disqualify separate, otherwise qualifying experimental work.

Employee interviews and reasonable estimates may assist substantiation when supported by a credible factual basis. They are not a substitute for demonstrating that qualifying research occurred and linking expenditures to it. Retain project records, payroll information, technical evaluations, invoices, and relevant contracts, and explain allocation methods. Substantiation disputes generally concern whether the taxpayer’s evidence adequately supports the claim.

Economic and Policy Implications

Congress made the federal research credit permanent in 2015. A discussion of policy proposals to make it permanent must therefore be identified as historical. The 2025 introduction of Section 174A materially changed domestic research deduction treatment, while Section 41 continued to impose its own narrower credit requirements. Taxpayers should distinguish the timing of expense recovery from eligibility for a credit.

System Technologies illustrates why governing law can matter to contractual risk, while the later Smith opinion demonstrates that this consideration does not guarantee a favorable funding determination. The combined practical implication is to examine payment mechanics, rights to reuse results, remedies, and performance obligations alongside the technical evidence. These decisions do not establish a general abandonment of written contract terms or a uniform expansion of eligibility for contractors.

Final Thoughts

The Gardner decisions discussed here should be understood within their actual subjects: capitalization, income inclusion, and penalties. They do not collectively supply an R&D-credit doctrine based on control over intellectual property or a broad primary-purpose test. Section 41, its regulations, and decisions directly applying the research-credit rules provide the relevant framework. Smith’s preliminary order and subsequent mixed outcome underscore the difference between surviving summary judgment and establishing the amount of an allowable credit.

For research-credit claims, document the technical uncertainty and experimentation, identify eligible expenditures, and evaluate funding and substantial rights under all relevant agreements. Apply the law effective for each tax year, including Section 174A where applicable. Accurate case characterization and reliable project-level evidence are essential to a defensible claim.
