Section 41 of the Internal Revenue Code provides the federal credit for increasing research activities, commonly called the R&D tax credit. Taxpayers must establish both qualifying activities and eligible expenditures. General Electric litigation offers useful context, but the cases discussed here concern different legal subjects. The 1926 patent decision, the 1971 government-contract decision, and the 2015 discovery order are separate disputes, not successive stages of an R&D credit case. This study distinguishes their actual holdings from practical observations about research-credit substantiation.

Historical Precedents and the Foundation of Corporate Tax Posture

United States v. General Electric Co., 272 U.S. 476 (1926), concerned antitrust law, patent licensing, and distribution arrangements for patented lamps. The Supreme Court upheld the particular licensing price restriction before it. It did not decide federal research-credit eligibility, establish the Section 41 business-component test, or create a general exemption from antitrust law for patent owners. Patent protection and research-credit qualification are distinct legal questions; obtaining a patent does not itself establish entitlement to a research credit.

General Electric Co. v. United States, 440 F.2d 420 (Ct. Cl. 1971), concerned a cost overrun under an Army contract for a chemical/biological warning system. The cost-plus-incentive-fee contract adjusted the target fee by 15 cents for each dollar that allowable costs fell below or exceeded the target. The court held that the contracting officer abused his discretion by refusing additional funding where GE could not reasonably have known of the overrun during performance and its failure to give advance notice was not attributable to faulty accounting. GE received judgment for $60,385.58. This was a contract-reimbursement ruling, not a Section 41 funded-research or intellectual-property ownership decision.

The 2014 Refund Suit and 2015 Discovery Ruling

In General Electric Co. v. United States, No. 3:14-cv-00190 (JAM), the District of Connecticut considered a refund dispute involving approximately $660 million, including interest, arising from corporate restructuring and sale transactions. Its September 15, 2015 discovery order addressed privilege. It did not adjudicate the qualification of aerospace or healthcare research expenses under Section 41.

Tax-Practitioner Privilege and Section 7525

The government challenged nearly 9,000 documents listed on GE’s privilege logs; these were privilege claims, not a statement that GE had produced all of the underlying documents. Section 7525 extends attorney-client-type confidentiality protection to qualifying tax-advice communications with federally authorized tax practitioners. It applies only in noncriminal tax matters before the IRS and noncriminal federal-court tax proceedings brought by or against the United States. The statute also excludes specified written communications promoting participation in tax shelters. Ordinary business advice and routine return preparation do not become privileged merely because an accountant provides them.

The government’s challenges in the GE discovery dispute fell into three categories:

Attachment Privilege: The government challenged attachments containing information available outside the confidential communication.

Predominant Purpose: The government questioned whether the communications primarily concerned business advice rather than legal or tax advice.

Standalone Documents: Nearly 1,000 entries lacked identification of an author or recipient, contrary to the applicable local privilege-log rule.

The court rejected the broad attachment and predominant-purpose challenges but required special-master review of the deficient standalone entries. An otherwise discoverable document does not become immune from discovery in all contexts when sent to counsel; its inclusion in a confidential request for legal advice can itself disclose a protected communication. The order did not establish an R&D-specific metadata requirement. For practitioners, its practical lesson is to document the basis for each privilege claim and keep that analysis separate from proof of credit eligibility.

Structural Analysis of Privilege and Documentation

Substantive Requirements of Section 41: The Four-Part Test

Section 41(d) imposes four requirements, applied to each business component. Research need not achieve an industry-wide breakthrough. Routine work fails when it does not satisfy the statutory tests or falls within an exclusion; complexity or novelty alone does not establish qualification. The following framework is independent of the GE privilege order.

Research Expenditure Test: Under the current version of Section 41(d)(1)(A), expenditures must be treated as domestic research or experimental expenditures under Section 174A. Earlier tax years used the applicable Section 174 standard. The governing tax-year rules must be applied.

The Technological Information Test: The research must be undertaken for the purpose of discovering information which is “technological in nature,” fundamentally relying on physical, biological, or computer sciences or engineering.

The Business Component Test: The taxpayer must intend that the information discovered will be useful in the development of a new or improved business component of the taxpayer.

The Process of Experimentation Test: Substantially all of the research activities must constitute elements of a “process of experimentation” related to a new or improved function, performance, reliability, or quality.

The “Process of Experimentation” and Technical Uncertainty

A process of experimentation evaluates alternatives to resolve uncertainty about capability, method, or appropriate design. Modeling, simulation, and systematic trial and error can provide evidence of that process. The following aviation and energy examples are illustrative applications, not findings about GE’s actual credit claims or the activities adjudicated in its 2015 case.

Phoenix Design Group, Inc. v. Commissioner, T.C. Memo. 2024-113, filed December 23, 2024, denied research credits claimed by a multidisciplinary engineering firm. The evidence did not establish qualifying research for the projects examined. Routine calculations and code-compliance work did not, on that record, demonstrate the necessary uncertainty and experimentation. The practical lesson is to explain the technical unknown, the alternatives evaluated, and how testing informed the design. The decision provides no basis for contrasting Phoenix’s evidence with a supposedly successful GE research-credit methodology.

The Shrink-Back Rule: Strategic Granularity in Large Projects

Treasury Regulation § 1.41-4(b)(2) requires application of the qualification tests first to the discrete business component, then to its most significant subset if the component fails, continuing to smaller subsets as necessary. The substantially-all threshold is 80% of research activities, measured using cost or another consistently applied reasonable basis. It is not automatically 80% of the entire project budget. A hypothetical engine program may contain a qualifying fuel-injection subset even when the broader component does not satisfy the tests; that subset must independently qualify.

In Little Sandy Coal Co. v. Commissioner, 62 F.4th 287 (7th Cir. 2023), the Seventh Circuit affirmed denial of the claimed credits because the taxpayer did not substantiate the required share of experimental activity. The record also did not support applying the shrink-back rule to qualifying subsets. The decision illustrates the limits of generalized project descriptions and unsupported estimates. GE product announcements and financial filings do not establish that GE successfully used shrink-back for T901, LEAP, or other engine programs.

Shrink-Back Application Levels

Discrete Business Component: A jet engine, using the GE9X as an illustrative product example.

Major Subsystem: A high-pressure turbine, if it is the appropriate subset for the particular analysis.

Specific Component: A ceramic-matrix-composite turbine shroud.

Smaller Element: A thermal-management software component, where the facts support that boundary. These examples illustrate possible analytical levels; they are not four mandatory regulatory tiers or evidence of GE’s tax treatment.

Phoenix Design Group also sustained accuracy-related penalties under Section 6662. Such penalties commonly apply at 20% of the relevant underpayment, but a documentation gap does not automatically trigger a penalty. The statutory basis, procedural requirements, and any reasonable-cause and good-faith defense must be considered separately.

Economic Risk and the Funded Research Exclusion

Section 41(d)(4)(H) excludes research to the extent funded by another person or governmental entity. Treasury Regulations §§ 1.41-4(c)(9) and 1.41-4A(d) require examination of the agreements, payment contingencies, and substantial rights retained by the researcher. Avoiding this exclusion does not by itself establish credit eligibility. The 1971 GE contract decision did not interpret these research-credit provisions.

System Technologies, Inc. v. Commissioner, No. 12211-21, was decided by an order dated January 3, 2025, not in 2024. The Tax Court denied the Commissioner’s motion for partial summary judgment on funded research. Although customers made progress payments, Indiana law supplied a refund remedy if the promised systems were not delivered, making ultimate payment contingent on successful performance. The order did not award the entire research credit or establish that every fixed-price contract qualifies. Contract labels alone are insufficient: review acceptance conditions, refunds, remedies, risk allocation, and rights in the results. Substantial rights need not be exclusive ownership; a retained right to use the research can qualify depending on the agreement, while incidental experience or a right requiring additional payment may not.

IRS Settlements and Corporate Restructuring

GE’s corporate tax disclosures provide context for large-company tax administration, but an aggregate IRS settlement cannot be characterized as an R&D credit recovery without evidence identifying the tax issues resolved. The cited 2016 Form 10-K does not establish the draft’s claimed connection between a $0.6 billion settlement, a 2017 R&D settlement, and the 2015 privilege order. Settlement amounts and financial-statement tax benefits also need not represent cash refunds or court-approved research-credit claims.

GE’s separation plan was announced in 2021, with GE HealthCare separating in January 2023 and GE Vernova in April 2024, leaving GE Aerospace as the continuing business. Tax matters agreements address responsibility for taxes, refunds, tax attributes, return preparation, record access, cooperation, and disputes. For example, the January 2, 2023 agreement between GE and GE HealthCare addresses these matters and preservation of the intended tax treatment of the separation. It does not itself establish that particular engineering costs satisfy Section 41.

Corporate Split and Tax Attribute Allocation

The GE HealthCare transaction was intended to qualify for tax-free treatment under Sections 368(a)(1)(D), 355, and related provisions. That treatment does not itself preserve or determine an R&D credit base amount. Section 41(f) and the applicable regulations separately govern controlled-group calculations and adjustments for acquisitions or dispositions. Historical research expenses and gross receipts must be handled consistently under the rules applicable to the transaction.

Implications for Future R&D Tax Credit Applications

The cases and statutory rules discussed here support a practical distinction: privilege protects qualifying communications, while substantiation establishes the activities and costs supporting a credit. A claim should be prepared with both questions in view. The following considerations are practical guidance, not additional holdings of the GE discovery order.

Section 174 Amortization and the Return of Domestic Expensing

For tax years beginning in 2022 through 2024, the Tax Cuts and Jobs Act generally required capitalization and five-year amortization of domestic research or experimental expenditures, with a 15-year period for foreign research. Public Law 119-21 subsequently added Section 174A, allowing a current deduction for domestic research or experimental expenditures for tax years beginning after December 31, 2024. Taxpayers may instead elect eligible amortization treatment. Foreign research remains subject to 15-year amortization under Section 174. Transition provisions address previously capitalized domestic costs; eligibility and procedures depend on the taxpayer and the election.

Deduction treatment and research-credit eligibility remain separate analyses. Section 41 limits creditable expense categories and activities, and Section 280C coordinates the credit with the deduction or capital account, including a reduced-credit election. A higher credit does not automatically force current domestic expenditures into five-year amortization. Nor does calling a document legal, business, or technical determine the tax treatment of the underlying costs. Classification turns on the expenditures and activities, not the privilege status of their documentation.

Contemporaneous Records and Metadata

The GE special-master order addressed privilege logs, not whether retrospective research narratives substantiate Section 41 credits. Treasury Regulation § 1.41-4(d) requires records in sufficiently usable form and detail to substantiate eligibility and amount. Contemporaneous records are valuable, but the regulation does not mandate CAD metadata, email threads, or one exclusive record format. Practical supporting materials can include:

CAD Metadata: Preserve dated design versions and connect changes to identified technical uncertainties.

Email Threading: Retain relevant technical exchanges that explain alternatives, testing, and design decisions, while assessing privilege separately.

Project-by-Project Accounting: Reconcile eligible wages, supplies, and contract research costs to the relevant activities and business components. Statistical sampling is not categorically prohibited; the IRS Form 6765 instructions expressly address its use. The selected method must support a defensible claim and meet the applicable filing requirements.

Global Minimum Tax and Pillar 2

GE Aerospace’s second-quarter 2025 Form 10-Q discussed global minimum taxes alongside favorable audit settlements and U.S. business tax credits. That disclosure does not demonstrate that Pillar Two nullified GE’s research credits. Pillar Two generally uses jurisdictional effective-tax-rate calculations for in-scope groups, rather than a single worldwide rate set by a tax matters agreement. Any effect on an incentive depends on the relevant rules, credit classification, jurisdiction, and available relief. The OECD’s January 2026 side-by-side package introduced further safe-harbor arrangements, including relief relevant to eligible U.S.-parented groups, while qualified domestic minimum top-up taxes remain relevant. A current analysis must consider the applicable year and implementing law; a simple claim that an R&D credit automatically produces an equal top-up tax is misleading.

Final Thoughts

The GE decisions discussed in this study address patent licensing, government-contract reimbursement, and privilege in a corporate tax-refund dispute. They do not form a sequence of research-credit rulings and do not demonstrate a judicially approved GE shrink-back strategy. Section 41, its regulations, and research-credit cases such as Phoenix Design Group and Little Sandy Coal supply the relevant qualification and substantiation framework.

For an R&D credit claim, identify each business component, describe the technical uncertainty and alternatives evaluated, preserve evidence of the work, and connect eligible expenditures to that activity. Analyze contractual funding and retained rights separately, use shrink-back where appropriate, and apply the deduction and credit rules for the correct tax year. A well-supported claim combines accurate technical evidence, reliable accounting, and a careful reading of the applicable law.
