The federal research credit under Internal Revenue Code Section 41 requires evidence of qualifying activities and eligible expenses. Recent litigation illustrates the consequences of weak substantiation and unfavorable customer contracts. The Utro transaction offers a separate acquisition-planning example: its purchase agreement is not an R&D tax court decision and does not establish a new legal framework for research credits.
The Utro Transaction: Asset Transfers and Substantiation
The February 28, 2020 Asset and Equity Purchase and Contribution Agreement identifies Smith’s Buyer, rather than Utro Buyer, as the purchaser of an undivided 59.284% interest in Smith’s Seller’s assets. A separate provision concerns Utro Buyer’s acquisition of Utro Seller’s assets. The agreement includes provisions concerning records, tax returns, claims, excluded assets, and retained liabilities. These contractual provisions do not demonstrate that either business conducted qualified research or claimed an R&D credit.
As a general tax principle, obtaining records or contractual claims does not automatically transfer another taxpayer’s federal tax credits, authority to amend its returns, or standing to sue for its tax refund. Entitlement depends on the taxpayer, transaction structure, and applicable law. Section 41(f)(3) contains acquisition and disposition adjustments relevant to research-credit computations; those adjustments should not be confused with purchasing a seller’s historical refund entitlement.
| Transaction Component | Impact on R&D Credit Continuity | Documentation Requirement |
|---|---|---|
| Undivided Interest Purchase | An asset ownership percentage does not automatically divide qualified research expenses or historical credits. | Identify the taxpayer that incurred expenses and evaluate applicable acquisition adjustments. |
| Tax Return Transfer | Access to returns does not itself authorize amendments or transfer credits. | Preserve returns, supporting calculations, and lawful access to technical records. |
| Claims/Causes of Action | A contractual assignment does not itself establish federal tax refund standing. | Review the assigned rights, statutory restrictions, and proper claimant. |
| Retained Liabilities | Private liability allocations do not necessarily bind the IRS. | Review indemnities, tax cooperation, and responsibility for responding to examinations. |
For acquisition planning, a practical inference is that tax diligence should address both credit entitlement and access to supporting evidence. The agreement alone cannot establish the value or existence of an R&D tax asset.
The Statutory Core: The Four-Part Test
Section 41(d) generally requires research to satisfy the research-expenditure test, be technological in nature, support a permitted purpose for a business component, and involve a qualifying process of experimentation. The requirements apply separately to business components, and statutory exclusions also apply.
Permitted Purpose and Technological in Nature
A business component may be a product, process, software, technique, formula, or invention. The research must concern a new or improved function, performance, reliability, or quality. Its experimental process must fundamentally rely on physical or biological sciences, engineering, or computer science. An employee’s professional credentials or a project’s uniqueness does not independently establish eligibility. Nothing in the Utro agreement proves that the acquired assets included qualifying innovations.
Elimination of Uncertainty
The relevant uncertainty concerns capability, method, or appropriate design at the beginning of the research. Treasury Regulation Section 1.41-4 does not require an advance in the common knowledge of the profession. Consequently, the existence of industry knowledge or standard software is not an automatic bar. Taxpayers must nevertheless demonstrate a real technical uncertainty and qualifying activities undertaken to resolve it.
Process of Experimentation
The process involves identifying uncertainty, considering alternatives, and evaluating them through methods such as modeling, simulation, or systematic trial and error. The substantially-all threshold is at least 80%, measured by cost or another consistently applied reasonable basis. A failed prototype or multiple failed designs is not a universal requirement. Reliable records should establish what evaluation actually occurred.
| Element of Experimentation | IRS Requirement (2025) | Common Pitfall in Documentation |
|---|---|---|
| Hypothesis Formulation | Identify uncertainty and alternatives; no universal requirement uses this particular label. | Describing only the final solution. |
| Systematic Evaluation | Establish how alternatives were evaluated. | Using generic design descriptions without supporting records. |
| Iterative Testing | Show the actual qualifying evaluation; repeated failures are not mandatory. | Assuming every revision proves experimentation. |
| 80% Threshold | Use cost or another consistently applied reasonable basis. | Estimating the ratio without a reliable factual foundation. |
Phoenix Design Group: Engineering Activities and Evidence
In Phoenix Design Group, Inc. v. Commissioner, T.C. Memo. 2024-113, issued December 23, 2024, the Tax Court found that the taxpayer had not established qualified research for the sampled engineering projects. These included the Gerald Champion Military Psychiatric Unit, Baptist Memorial Hospital–North Mississippi, and Vanderbilt University Engineering and Science Building. Accuracy-related penalties followed under the parties’ stipulation; a credit disallowance does not automatically establish a penalty in every other case.
The Limits of a Standard Design Process
The taxpayer’s description of a six-stage design process did not establish that the actual activities met the experimentation requirement. Project records and testimony must substantiate the claimed research; naming design stages cannot substitute for that evidence.
Implications for Architects and Engineers
Routine calculations and code compliance alone do not demonstrate qualified research. The decision does not categorically exclude engineering work on unique buildings. The shrinking-back rule can permit analysis of a qualifying subset when a whole component fails, but the taxpayer still needs evidence supporting that subset.
Meyer, Borgman & Johnson: Contracts and Funded Research
The Eighth Circuit affirmed the denial of research credits in Meyer, Borgman & Johnson, Inc. v. Commissioner in 2024. The funded-research exclusion turns on the relevant agreements and whether payment is contingent on successful research. A fixed fee and the possibility of cost overruns do not, by themselves, establish the necessary economic risk.
Economic Risk and Fixed-Price Contracts
Fairchild Industries illustrates arrangements in which payment depended on satisfying contractual requirements and payments could be recoverable if performance failed. MBJ’s circumstances did not establish comparable research-success risk. These decisions require analysis of contractual obligations and remedies, rather than reliance on a fixed-price label.
Substantial Rights and Payment Risk
Under Treasury Regulation Section 1.41-4A(d), substantial rights in research results are a separate consideration. A provider generally must retain substantial rights without paying for their use and bear the relevant research-success risk. A customer does not automatically qualify for a credit merely because its provider’s research is funded; the customer must independently satisfy the applicable rules. No conclusion about the Utro parties’ contracts follows from the purchase agreement alone.
| Case/Precedent | Payment Structure | Risk Determination | Result |
|---|---|---|---|
| Fairchild Industries | Payments tied to contractual performance requirements. | Research-success risk supported by the contractual terms. | Favorable funded-research determination; other eligibility requirements remain relevant. |
| MBJ v. Commissioner | Engineering service agreements. | Cost-overrun risk did not establish payment contingency on successful research. | Funded-research disallowance affirmed. |
| Populous Holdings | Fixed-fee architectural agreements considered by the court. | Contract-specific analysis of risk and retained rights. | Favorable funded-research determination for the contracts at issue, not all fixed-fee contracts. |
| System Technologies | Industrial finishing-system agreements. | Indiana-law remedies informed the analysis of payment risk. | A 2024 order denied the IRS partial summary-judgment motion on funding; this procedural result is not blanket approval of every claimed credit. |
IRS Review of Research Credit Refund Claims
IRS guidance describes classification and validity review of research-credit refund claims. It does not substantiate the source’s description of a newly introduced automated “Classifier” system that independently imposes new eligibility law. Procedural acceptance and substantive credit eligibility are different questions.
Required Information
For claims postmarked on or after June 18, 2024, IRS guidance generally requires identification of the business components, a description of research activities for each component, and totals for qualified wages, supplies, and contract research. The requirement to initially provide individual researchers’ names and what each sought to discover was waived; that information may still be requested during an examination. The claim also requires verification under penalties of perjury.
The IRS’s January 2025 guidance states that the activity description need not explain the four-part test in detail. It should describe what was done and how, rather than merely repeat statutory language. A January 2026 procedural update extends the opportunity to perfect specified deficient claims through January 10, 2027, with 45 days to respond to the applicable request. A sufficient initial submission does not guarantee allowance.
Research Expensing: Sections 174 and 174A
The source’s statement that domestic expensing restoration remains proposed legislation is outdated. Public Law 119-21, enacted July 4, 2025, added Section 174A, generally allowing current deductions for domestic research or experimental expenditures in tax years beginning after December 31, 2024. Foreign research expenditures remain subject to 15-year amortization under Section 174.
Coordinate Deductions and Credits
Research deductions and research credits have related but different eligibility and expense rules. A deduction does not automatically establish a Section 41 credit. Section 280C also coordinates deductions with the credit, including the reduced-credit election where applicable.
Transition Rules
For tax years beginning in 2022–2024, the prior rules generally required five-year domestic and fifteen-year foreign amortization. The 2025 law introduced elections for remaining domestic balances and retroactive relief for eligible small businesses. Revenue Procedure 2025-28 addresses implementation. Eligibility, election deadlines, and accounting methods require year-specific review; retroactive relief should not be assumed to remain available indefinitely.
Measuring the Substantially-All Requirement
A useful expression is: experimentation percentage = qualifying experimentation activities divided by the relevant research activities for the business component, multiplied by 100. The numerator and denominator must use the same permissible measurement basis. The threshold is at least 80%; the denominator is not automatically every hour spent on the entire commercial project.
In Little Sandy Coal Co. v. Commissioner, the Seventh Circuit emphasized the need to substantiate the experimentation share. Novelty of a vessel or its physical components was not a substitute for analyzing activities. Direct supervision or support that may generate qualified wages does not automatically count as experimentation in this distinct component-level calculation. The shrinking-back rule may require a supported analysis of a smaller subset.
Practical Steps for Research Credit Claims and Acquisitions
The following are practical recommendations, not a new set of universally mandatory record formats.
Contemporaneous Narrative Development
Record the technical uncertainty, alternatives considered, evaluations performed, and results as work progresses. Preserve dated designs, test data, emails, and other ordinary business records. A later study can explain those records, but unsupported recollections are vulnerable. There is no universal rule that every valid claim requires a formal real-time research diary.
Activity-Level Time and Expense Support
Use descriptions that accurately distinguish qualifying work from administration and routine delivery. Reconcile allocations to payroll and project records. The table retains the source’s headings, but its examples are illustrative: wording alone never establishes compliance.
| Poor Time Entry | Compliant Time Entry (2025) |
|---|---|
| Project Management | Evaluated Material X alternatives against Stress Load Y; supporting test records identify the unresolved technical issue. |
| Engineering Design | Compared CAD Models V1 and V2 to evaluate vibration uncertainty; retained simulation results. |
| Client Meeting | Reviewed Prototype A thermal-test results and selected the next technical evaluation; separate routine client administration. |
| Coordination | Evaluated alternative subsystem tolerances to resolve a documented integration uncertainty; routine scheduling remains separate. |
Contract Review
Review payment conditions, acceptance standards, refund obligations, ownership and use rights, and applicable law. Contract language should reflect the actual commercial arrangement. Adding references to technical milestones cannot transform otherwise funded research into qualifying research.
Acquisition Due Diligence
- Determine the proper claimant and any acquisition-related computation adjustments.
- Preserve access to technical records, expense support, and knowledgeable personnel.
- Assess the basis for activity allocations and the substantially-all calculation.
- Specify tax cooperation, retention obligations, and appropriate indemnities.
Applying the Shrinking-Back Rule
Where a business component fails the requirements, assess the most significant subset and continue as the regulation directs. Preserve the evidence for each claimed subset. Shrinking back is a legal analytical rule, not permission to select favorable activities without establishing a qualifying component.
