The Intellectual Foundation of Innovation Incentives

John M. Golden and Hannah J. Wiseman’s study of the fracking revolution describes innovation as the product of interacting policies, including public research support, tax incentives, and intellectual property protection. Their account provides a useful policy framework for considering how government can encourage investment when private firms cannot capture all the benefits of their work.

That policy framework must be distinguished from tax eligibility. Section 41 does not require a taxpayer to advance the common knowledge of an entire scientific or engineering field. Existing technologies can be used in qualifying research. The relevant questions concern the taxpayer’s technical uncertainty, research activities, business components, and compliance with the statutory exclusions.

The Role of Non-Patent Incentives in Innovation

Tax relief and direct public support can encourage research alongside patents. A patent is not a prerequisite for the research credit, and holding a patent does not by itself establish that every claimed expense qualifies.

These incentives may coexist. The source’s suggestion that courts are tightening research-credit standards to counteract overlapping patent and tax benefits is unsupported. Credit disputes turn on applicable law and the evidence in each case.

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

Research expense recovery and research-credit eligibility are related but distinct. A deductible research cost is not automatically a qualified research expense for Section 41. Historical cases must be read under the law applicable to their tax years.

The Research-Expense Threshold of Uncertainty

Treasury Regulation Section 1.174-2 describes research and experimental expenditures in terms of activities intended to eliminate uncertainty about developing or improving a product. Uncertainty concerns capability, method, or appropriate design, assessed using information available to the taxpayer. Commercial uncertainty, a demanding customer, or an unfinished design does not by itself establish qualifying technical uncertainty.

The Tax Cuts and Jobs Act required five-year amortization for domestic research and fifteen-year amortization for foreign research for tax years beginning after December 31, 2021. Public Law 119-21 changed that framework in 2025. Section 174A generally permits current deductions for domestic research expenditures paid or incurred in tax years beginning after December 31, 2024, with an elective capitalization alternative. Foreign research remains subject to fifteen-year amortization under Section 174. Transitional elections can affect previously capitalized domestic costs; Revenue Procedure 2025-28 provides implementing procedures. Accordingly, mandatory five-year domestic amortization is not an accurate statement of the general current rule.

The Four-Part Test of Qualified Research

The Section 41 analysis generally addresses four connected requirements, applied to each business component:

• Research-expense requirement: The expenditure must meet the applicable research-expense standard. Current Section 41(d)(1)(A) refers to Section 174A; older cases apply the earlier Section 174 reference.
• Technological information: The research must fundamentally rely on physical or biological science, engineering, or computer science.
• Qualified purpose: The work must concern a new or improved business component’s function, performance, reliability, or quality. A business component includes a product, process, software, technique, formula, or invention held for sale, lease, or license, or used in the taxpayer’s business.
• Process of experimentation: Substantially all of the relevant research activities must constitute elements of an evaluative process addressing technical uncertainty.

The shrinking-back rule in Treasury Regulation Section 1.41-4(b)(2) permits analysis of progressively smaller subsets of a business component when the overall component fails the qualification requirements. It is not a general permission to select isolated expenses without establishing qualifying activities.

Wiseman and the Trade or Business Requirement

Wiseman v. Commissioner, T.C. Memo. 1995-203, addressed whether a taxpayer could aggregate a loss from one partnership with income from another under Section 469. The dispute involved ground rents, their treatment as nonpassive income, and the then-applicable activity-aggregation regulations. The Tax Court rejected the taxpayer’s proposed aggregation.

Wiseman was not a Section 41 research-credit decision. It did not establish the shrinking-back rule or the research-credit business-component test. Treating its passive-activity analysis as a foundation for those rules conflates separate statutory regimes. Hannah J. Wiseman’s innovation-policy scholarship is also distinct from the litigation involving Shirley McVay Wiseman.

The connection to a trade or business remains relevant under the research provisions, but it must be analyzed under those provisions and their applicable authorities. A profit objective alone does not establish a research credit, and a passive-activity classification does not determine whether technical work satisfies the four-part test.

Documentation Lessons: Phoenix Design Group, Inc. v. Commissioner

In Phoenix Design Group, Inc. v. Commissioner, T.C. Memo. 2024-113, issued December 23, 2024, the Tax Court considered three trial projects of a firm designing mechanical, electrical, plumbing, and fire-protection systems. It found no qualified research in those projects. The parties had agreed that this three-project sample would be nonbinding as to the remaining projects.

The Limits of Routine Engineering Evidence

The case illustrates why professional expertise, complex facilities, and changing drawings do not alone prove qualified research. Evidence must identify the technical uncertainty and show how the taxpayer evaluated alternatives to resolve it. Calculations applying established information may demonstrate competent engineering without demonstrating experimentation.

The Linear vs. Iterative Distinction

A standard design workflow is not sufficient proof of an experimental process. Conversely, a workflow’s linear presentation does not categorically disqualify its underlying activities. The following table preserves the source’s design-stage comparison while replacing its unsupported blanket eligibility labels with evidence questions.

The Limits of the Shrinking-Back Rule

The court could not identify qualifying smaller components from the evidence presented. The practical lesson is to connect activities and supporting records to the component being claimed. This does not establish a universal legal requirement for a particular timekeeping system or a prescribed hypothesis log.

Production Wages: Little Sandy Coal Co. v. Commissioner

Little Sandy Coal Co. v. Commissioner, T.C. Memo. 2021-15, was affirmed by the Seventh Circuit in 2023. The dispute concerned a shipbuilder’s tanker and dry-dock projects and whether the taxpayer established the substantially-all requirement.

The Numerator/Denominator Problem

The percentage concerns relevant research activities, not how much of a vessel is new. If $200,000 of a properly determined $1 million research-activity denominator constitutes experimentation, the ratio is 20%. But labeling the remaining $800,000 “production labor” does not establish that it belongs outside the numerator. The activities must be examined.

The Seventh Circuit’s Clarification

The appellate court rejected categorical exclusion of pilot-model production from the numerator merely because the work directly supported research. It nevertheless affirmed because the taxpayer failed to provide a principled evidentiary basis for meeting the threshold. Neither production wages nor engineering wages qualify automatically by job title. The taxpayer must substantiate what the employees did and how those activities relate to experimentation.

Contractual Risk and the Funded Research Exception

Section 41 excludes research to the extent funded by another person. Treasury Regulation Section 1.41-4A(d) addresses both payment risk and substantial rights. When payments are not contingent on successful research, retained rights and the amount of funding still matter: potentially qualifying costs exceeding funding require separate analysis. If the researcher retains no substantial rights, the research is treated as fully funded under the regulation.

Success-Contingent Payment as a Risk Indicator

The source characterized the early Smith proceedings as a favorable 2025 result. Denial of summary judgment was not a final determination of credit entitlement. Milestones, fixed prices, and termination clauses must be read in context; none automatically proves that payment depends on technical research success.

In the later merits opinion, Smith v. Commissioner, T.C. Memo. 2026-50, filed June 16, 2026, the Tax Court found that payments under none of the six sample contracts were contingent on research success. Substantial rights were retained under four contracts, permitting potential partial credits for qualifying research expenses exceeding payments. The court could not determine the precise partial-credit amounts, if any, on the evidence before it.

The Interpretation of Intellectual Property Rights

Smith also illustrates why foreign copyright protection cannot simply be assumed to override contractual transfers. For two sample projects, the court found that the firm lacked substantial rights. Rights to reuse research can be substantial without being exclusive, but institutional experience alone is not a substitute for enforceable rights.

In System Technologies, Inc. v. Commissioner, Docket No. 12211-21, the January 3, 2025 order denied the IRS’s motion for partial summary judgment on funded research. Applying Indiana law to the agreements, the court found that failure to deliver would require refunds, making ultimate payment contingent on success. This was a contract-specific funding determination, not a ruling that state law invariably overrides contracts or that every claimed expense qualifies.

The Administrative Shift: FAA 20214101F and Claim Review

FAA 20214101F described five information items for research-credit refund claims. It is nonprecedential IRS advice, and subsequent administrative guidance changed the submission requirements.

Effective June 18, 2024, the IRS waived the requirement to submit the identities of individuals performing each research activity and the information each individual sought to discover. Its research-credit refund-claim FAQ 21 requires the following information at filing:

• Identify all business components to which the claim relates for the year.
• Identify the research activities performed for each business component.
• Provide total qualified wage, supply, and contract-research expenses for the claim year; Form 6765 may be used.

The waived employee-level information may still be requested during examination. Claim-validity screening is distinct from substantive examination. The source’s assertion that an automated classifier rejects claims before any human review is unsupported; IRS guidance describes review by personnel.

Future Implications for R&D Tax Credit Applications

The practical response to these cases is to build a defensible connection between the statutory requirements, technical evidence, and claimed costs. That connection matters under both historical amortization rules and the newer domestic deduction regime.

Strategic Retooling of R&D Studies

Useful records may include:

• Technical uncertainty records: Identify what available information did not establish about capability, method, or design when the research began.
• Evaluation records: Preserve alternatives considered, calculations, models, simulations, tests, results, and the reasons for subsequent decisions.
• Component and cost records: Connect employee activities, supplies, and contractor costs to the relevant component or subcomponent, with a supportable allocation method.
• Contract records: Retain agreements and amendments showing payment conditions and rights to use research results.

Contemporaneous records generally make factual reconstruction easier. These are practical documentation suggestions, not a mandatory format imposed by every case. Interviews and later explanations should be evaluated alongside the underlying evidence rather than treated as either automatically sufficient or categorically unusable.

The Impact of Input Additionality and State Credits

Input additionality asks whether an incentive increases research spending beyond what otherwise would occur. That is a policy-evaluation question, not an additional element of a taxpayer’s Section 41 claim. The source’s precise claims about short- and long-run spending responses should not be treated as universal estimates; effects depend on the jurisdiction, period, program design, and research method.

State incentives can influence location decisions, but each state’s rules and conformity to federal changes require separate review. For international comparisons, domestic research generally receives current deduction treatment under Section 174A, while foreign research remains subject to Section 174 amortization. Research outside the United States, Puerto Rico, and U.S. possessions is excluded from the federal Section 41 credit. Deduction timing and credit eligibility therefore require separate comparisons.

Final Thoughts

Wiseman’s innovation-policy scholarship provides context for public support of research; Wiseman v. Commissioner addresses a different passive-activity issue. Neither substitutes for the statutory research-cred
