Navigating the Technological Frontier: A Comprehensive Analysis of the Elimination of Uncertainty Test in Nebraska’s Research and Development Tax Credit Framework

The Elimination of Uncertainty test is a mandatory legal standard requiring that a business component’s development involves resolving technical unknowns regarding its capability, method, or design through structured research. In the context of the Nebraska Research and Development tax credit, this test serves as the primary gateway for aligning state-level innovation incentives with federal Internal Revenue Code standards.

The statutory framework for the Nebraska Research and Development tax credit is built upon a direct linkage to federal guidelines, specifically those found in Internal Revenue Code (IRC) Section 41 and Section 174.1 For a business to successfully claim the Nebraska credit, it must first establish that its activities constitute “qualified research.” This determination hinges on the Four-Part Test, of which the “Elimination of Uncertainty” is arguably the most critical and frequently scrutinized by the Nebraska Department of Revenue.2 This test ensures that the state is subsidizing genuine technical breakthroughs rather than routine business expenses or aesthetic modifications. By requiring taxpayers to prove that the information available at the project’s outset did not establish the path to success, the law separates experimental innovation from standard industrial production.4

The Statutory Integration of Nebraska and Federal Tax Law

Nebraska’s approach to research incentives is characterized by its high degree of conformity to federal definitions. The Nebraska Advantage Research and Development Act, and its successor, the ImagiNE Nebraska Act, both leverage the language of IRC Section 174 to define eligible expenditures.6 This means that the Nebraska Department of Revenue does not operate in a vacuum; it applies decades of federal case law and Treasury Regulations to determine if a Nebraska-based activity is truly “experimental in the laboratory sense”.2

Under Nebraska Revised Statute § 77-5803, any business firm making expenditures in research and experimental activities as defined in Section 174 of the Internal Revenue Code is eligible for the state credit.8 The credit is essentially a percentage of the federal credit allowed under Section 41, which creates a “nexus” requirement: if an activity does not qualify for the federal R&D credit, it generally cannot qualify for the Nebraska credit.7 This interdependence simplifies the initial calculation for multi-state entities but elevates the risk, as an IRS disallowance of the federal credit typically triggers an automatic disallowance of the Nebraska portion.9

Comparative Credit Rates in Nebraska

Nebraska distinguishes itself from other states by offering an “enhanced” credit rate for activities that leverage the state’s academic infrastructure. While the baseline credit is competitive, the bonus for university collaboration is a powerful driver for the state’s burgeoning biotech and agricultural technology sectors.1

The state’s fiscal commitment to this program is evident in its refundability. Unlike many federal credits that only offset current tax liability, the Nebraska R&D credit can be claimed as a refundable income tax credit or used to obtain a direct refund of state sales and use taxes paid.1 This feature is particularly vital for startups and loss-making entities that possess significant technical uncertainty but lack immediate taxable income to offset.1

Defining the Three Pillars of Technological Uncertainty

At its core, the Elimination of Uncertainty test identifies three specific types of technical “unknowns” that a project must aim to resolve. The presence of any one of these uncertainties at the beginning of the research phase is sufficient to satisfy the legal requirement under Section 174.4

Uncertainty of Capability

Uncertainty of capability exists when a taxpayer is unsure whether the intended objective is even achievable.3 This is the highest form of uncertainty and is common in the earliest stages of experimental science. For example, a Nebraska-based materials science firm attempting to develop a new biodegradable plastic that can withstand high-pressure steam sterilization without deforming faces a capability uncertainty.5 If the firm does not know if a polymer with these conflicting properties can exist, they are attempting to eliminate a capability uncertainty.

Uncertainty of Method

Even if a business knows that a result is possible, it may not know the “how”—the specific methodology required to reach that result.3 This is frequently seen in manufacturing process improvements. A fabrication shop may know that it can use a specific laser-cutting technique to create a complex part, but they may not know the exact sequence of power settings, gas mixtures, and cutting speeds required to prevent heat-affected zone (HAZ) cracking in a new grade of titanium.3 The research conducted to establish this methodology qualifies under the test.

Uncertainty of Design

The most common form of uncertainty involves the “appropriateness of design”.3 This recognizes that while a product can be built and the method is known, the optimal configuration remains elusive. This uncertainty drives the iterative prototyping process. In the context of software development, a team might know they can build a specific data-routing engine, but they may not know which architectural design will provide the necessary scalability to handle 10 million concurrent users without latency spikes.14 The systematic evaluation of different software architectures is the process of eliminating design uncertainty.

The Interaction of Uncertainty and the Four-Part Test

The Nebraska Department of Revenue evaluates research activities through the lens of the Four-Part Test, which was developed by Congress to narrow the scope of the credit to activities that genuinely drive innovation.2 The Elimination of Uncertainty test does not stand alone; it is the catalyst for the remaining three requirements.

1. Permitted Purpose: The research must be aimed at improving the functionality, performance, reliability, or quality of a “business component”.3 If the goal is merely aesthetic, such as changing the color of a tractor’s chassis, there is no technical uncertainty to eliminate, and the activity fails.2
2. Technological in Nature: The resolution of the uncertainty must fundamentally rely on the “hard sciences”.3 This includes engineering, physics, chemistry, biology, or computer science. Activities based on soft sciences like psychology or market research are explicitly excluded because they do not address technological uncertainty.15
3. Process of Experimentation: This is the “how” of the R&D credit. Once uncertainty is identified, the taxpayer must engage in a systematic evaluation of alternatives—such as modeling, simulation, or trial-and-error—to eliminate that uncertainty.4 Merely trying one thing and succeeding by chance is not experimentation; there must be a structured approach to testing hypotheses.16

Local State Revenue Office Guidance: Compliance and Documentation

The Nebraska Department of Revenue (DOR) provides administrative guidance that clarifies the procedural requirements for claiming the credit. One of the most critical distinctions in Nebraska is that, unlike many other state incentive programs, the R&D credit does not require prior application or registration.12 A business simply performs the research, documents the uncertainty, and claims the credit on its tax return.

Mandatory Filing Forms

To claim the credit, businesses must use specific state forms that tie their Nebraska expenditures to their federal calculations.

The DOR requires that all claimants retain records for at least three years after filing the return, though practitioners often recommend four years to align with state audit statutes.1 These records must demonstrate the “nexus” between the expenses claimed (wages, supplies, and contract research) and the specific activities undertaken to eliminate technical uncertainty.1

The E-Verify Requirement: A Potential Pitfall

A unique aspect of Nebraska’s local guidance is the E-Verify mandate. Since October 1, 2009, any business firm claiming the research credit must electronically verify the work eligibility status of all newly-hired employees in Nebraska during the tax year for which the credit is claimed.1 This is a “cliff” requirement: failure to timely use E-Verify for even a single new hire can disqualify the entire R&D credit for that tax year.1 The Department of Revenue views this as a condition of eligibility, ensuring that tax-subsidized innovation is performed by a legally authorized workforce.12

Real-World Application: The “Nut & Co.” Case Study

To understand how the Elimination of Uncertainty test applies in a practical Nebraska business context, we can examine the illustrative case of “Nut & Co.,” an agricultural equipment manufacturer.7

Phase 1: Identifying the Uncertainty

Nut & Co. identified a market need for a high-efficiency nut-shelling machine that reduced kernel breakage. The traditional method used high-pressure air to “blow” shells off, but this often damaged the delicate nut meat. The company proposed a “suction” method instead. At the outset, they did not know if a vacuum-based system could generate sufficient force to crack hard shells while leaving the kernel intact.7 This established a Capability Uncertainty.

Phase 2: Defining the Method and Design

As the project moved into engineering, the team faced further questions. What air-flow velocity was optimal? What material should the separation chamber be made of to prevent abrasive wear from the shells?.7 They did not have the answers to these questions in any existing engineering handbook. This established Method and Design Uncertainty.

Phase 3: The Process of Experimentation

To eliminate these uncertainties, the company followed a structured path:

• Conceptual Design: Engineers created fluid dynamic models to simulate air flow.7
• Prototyping: They built three different nozzle configurations and five different chamber geometries.7
• Testing and Iteration: They ran trials with different nut varieties (pecans vs. walnuts), measured breakage rates, and modified the vacuum pressure based on the data.7

By documenting that the final design could only be proven effective through this iterative prototyping and testing, Nut & Co. satisfied the Elimination of Uncertainty test. They successfully demonstrated that the information needed to build the machine was not available until they performed the research.7

Sector-Specific Perspectives on Uncertainty in Nebraska

Nebraska’s diverse economy means that “technological uncertainty” takes many forms. The Department of Revenue’s audit focus varies depending on whether the business is in the fields of agriculture, manufacturing, or software.1

Agribusiness and Crop Science

In Nebraska’s agricultural sector, uncertainty often revolves around biological and chemical variables. For instance, a firm developing a new drought-resistant seed coating faces uncertainty regarding how the chemical compound will interact with different soil pH levels across Nebraska’s diverse geography.1 Because the success of the coating cannot be predicted without field trials (experimentation), it meets the uncertainty threshold.

Advanced Manufacturing and Fabrication

For Nebraska’s manufacturing hub, uncertainty is often found in the “hard” sciences of metallurgy and mechanical engineering. A fabrication business that adopts a new robotic welding system for high-strength steel must eliminate uncertainty regarding the “heat-affected zone” and the structural integrity of the welds under stress.3 This is not a “standard practice” setup; it requires testing and validation of the robotic parameters.3

Software and Financial Technology (FinTech)

Software development is a significant part of Nebraska’s “Silicon Prairie.” However, not all software work qualifies. Routine debugging or aesthetic web design does not involve technical uncertainty.14 To qualify, a software project must tackle challenges such as developing a new encryption algorithm, optimizing a database for massive throughput, or integrating disparate systems using a novel API architecture where the data-mapping method is unknown at the start.16

Historical Statistics and Economic Impact

The Nebraska Advantage Research and Development Act has provided a substantial fiscal tailwind for the state’s innovators. Historical data from the Legislative Audit Office illustrates the program’s growth and the significant investments made by Nebraska firms.24

The fact that the actual usage has doubled the initial legislative estimates suggests that Nebraska businesses are increasingly engaging in high-level R&D.24 However, the lack of a program cap has occasionally led to concerns about fiscal predictability for the state budget.24

The Evolution of the Law: From Advantage to ImagiNE

The transition from the Nebraska Advantage Act to the ImagiNE Nebraska Act on January 1, 2021, brought several administrative changes, though the core “Elimination of Uncertainty” test remained unchanged.25

Key Administrative Shifts

The ImagiNE Nebraska Act was designed to modernize the state’s incentive structure. For R&D-heavy companies, the most significant change is the removal of the “Qualification Audit” requirement prior to claiming benefits.25 Under the old Advantage Act, many companies were frustrated by delays as they waited for the Department of Revenue to audit their investment and employment levels before they could use their earned credits.26 Under ImagiNE, businesses can use their credits as soon as they reach their thresholds, with the Department of Revenue retaining the right to audit at a later date.25

Despite these shifts, the R&D credit itself continues to function as a subset of these larger incentive packages, maintaining its own set of 20-year carryforward rules and refundability options.1

Audit Defense: Substantiating the Uncertainty

In an audit, the Nebraska Department of Revenue will look for “contemporaneous documentation”.13 This means records created at the time the research was being performed, not months or years later. To successfully defend the Elimination of Uncertainty test, a business must be able to present:

• Initial Project Briefs: Documentation showing the technical challenges identified at the start of the project.15
• Technical Logs: Records of failed tests, abandoned designs, and modified hypotheses.16
• Time Tracking: Detailed evidence of which engineers were working on which technical uncertainties.13
• Evidence of Hard Science: Documentation that the solutions were found through engineering or scientific principles, not through business intuition or marketing.15

The Department of Revenue has become increasingly sophisticated in its review of these credits, often looking for the specific “nexus” between the QREs (Qualified Research Expenses) and the activities that supposedly eliminated the technical uncertainty.1

The Impact of Federal Capitalization (Section 174)

A major shift in the R&D landscape occurred with the 2017 Tax Cuts and Jobs Act (TCJA). Historically, Section 174 allowed businesses to immediately deduct their research expenses.9 Starting in 2022, companies are required to capitalize and amortize these expenses over five years (domestic) or fifteen years (foreign).30

Because Nebraska’s R&D credit is tied to these federal definitions, this change has a profound impact on the cash flow of Nebraska firms.1 While the state credit remains a percentage of the federal credit, the underlying math of the deduction has changed, making the “Elimination of Uncertainty” even more critical. If an activity is not classified as a Section 174 expense (meaning it didn’t involve technical uncertainty), it cannot be amortized, but it also cannot be used to generate the Nebraska R&D tax credit.9 This “linkage risk” means that a failure to meet the uncertainty test now results in both the loss of a tax credit and the potential for a forced re-characterization of the expense on the federal level.9

Conclusion: The Strategic Importance of the Uncertainty Test

The Elimination of Uncertainty test is far more than a technicality; it is the philosophical anchor of Nebraska’s research and development incentives. By requiring businesses to operate at the edge of their technical knowledge, the state ensures that its tax dollars are fueling the breakthroughs that will define the future of agriculture, manufacturing, and technology. For the modern Nebraska business, navigating this test requires a dual commitment to technical innovation and rigorous administrative compliance.

Successful firms are those that not only embrace the risk of failure inherent in true research but also meticulously document that risk from the very first day of the project. Through the systematic elimination of capability, method, and design uncertainties, Nebraska companies can leverage one of the nation’s most favorable tax environments—including 15% to 35% credits and full refundability—to turn today’s technical unknowns into tomorrow’s commercial successes. As the state transitions into the ImagiNE Nebraska era, the fundamental requirement remains: to earn the credit, one must first face, and then systematically overcome, the uncertainty of innovation.
