Technical Analysis of Internal Revenue Code Section 41 and the Oregon Research and Development Tax Credit Framework

Internal Revenue Code Section 41 provides a federal tax credit for increasing qualified research activities, serving as the technical foundation for Oregon’s specific R&D incentives aimed at the semiconductor industry. While federal law offers a broad 20 percent credit for diverse innovation, Oregon’s statutory framework modifies these rules to target semiconductor-related research conducted within state borders, requiring rigorous certification through Business Oregon and the Department of Revenue.

Technical Foundation: Federal Internal Revenue Code Section 41

To understand the application of the research and development credit in Oregon, one must first master the intricate mechanics of Internal Revenue Code (IRC) Section 41. Formally known as the “Credit for Increasing Research Activities,” Section 41 serves as the primary statutory mechanism for incentivizing technological innovation at the federal level, which state jurisdictions then adopt or modify. The credit is not an entitlement for any company conducting “research” in the colloquial sense; rather, it is a strictly defined tax benefit that requires adherence to the “Four-Part Test” and specific expenditure classifications.

The Evolution of Qualified Research

Qualified research, as defined under Section 41(d)(1), is research for which expenditures may be treated as expenses under Section 174, and which meets four specific criteria. The purpose of this research must be to discover information that is “technological in nature” and intended to be used in the development of a new or improved “business component” of the taxpayer. A business component refers to any product, process, computer software, technique, formula, or invention that is held for sale, lease, or license, or used by the taxpayer in its own trade or business.

The Four-Part Test Analysis

The first requirement is the Section 174 Test, which dictates that the expenditures associated with the activity must represent research and development costs in the experimental or laboratory sense. This means the costs must be incurred for activities intended to discover information that would eliminate uncertainty concerning the development or improvement of a product.

The second requirement is the Technological in Nature Test. For research to be qualified, the process of experimentation used to discover information must fundamentally rely on the principles of physical science, biological science, engineering, or computer science. This precludes research in the social sciences, arts, or humanities. Importantly, a taxpayer does not need to exceed the common knowledge of skilled professionals in their field to satisfy this test; they merely need to seek information that is not already known to them through a technological process.

The third requirement is the Elimination of Uncertainty Test. Uncertainty exists if the information available to the taxpayer does not establish the capability or method for developing or improving the business component, or the appropriate design of the business component. This test focuses on the objective of the research: was it intended to solve a specific technical problem for which the solution was not readily apparent at the outset?

The fourth and perhaps most scrutinized requirement is the Process of Experimentation Test. This requires that “substantially all” (defined as 80 percent or more) of the research activities must constitute elements of a process of experimentation. A process of experimentation involves the identification of uncertainty, the identification of one or more alternatives intended to eliminate that uncertainty, and an evaluative process—such as modeling, simulation, or a systematic trial-and-error methodology—to test those alternatives.

Classification of Qualified Research Expenses (QREs)

Under Section 41(b), qualified research expenses are divided into two primary categories: in-house research expenses and contract research expenses.

Legislative Interactions and Section 174 Amortization

A critical development in recent years is the interaction between Section 41 and Section 174. Historically, companies could immediately expense R&D costs under Section 174. However, starting in 2022, federal law required these costs to be capitalized and amortized over five years for domestic research and fifteen years for foreign research. While Section 41 provides a tax credit (a dollar-for-dollar reduction in liability), Section 174 governs the deductibility of the expenses themselves. This “Section 174 cliff” has significantly increased the tax burden on innovative firms, as they can no longer offset their current-year income with 100% of their R&D spend.

Oregon Statutory Framework: From General to Targeted Incentives

The state of Oregon has had a complex relationship with the R&D credit, shifting from a broad-based corporate incentive to a highly targeted program designed to anchor the “Silicon Forest”—the state’s hub for semiconductor manufacturing and design.

The Discontinuation of General Credits (ORS 317.152 and 317.154)

Historically, Oregon offered two primary research credits. The first, under ORS 317.152, was a 5 percent credit for increases in qualified research expenses, determined in accordance with IRC Section 41. The second was the Alternative Qualified Research Activities Credit under ORS 317.154, which was available for research expenses exceeding 10 percent of Oregon sales. Both of these credits sunsetted for tax years beginning on or after January 1, 2018. For several years, Oregon was one of the few technology-heavy states without an active R&D credit.

The Resurrection: The Research and Development Tax Credit for Semiconductors

In July 2023, Governor Tina Kotek signed House Bill 2009, creating the “Research and Development Tax Credit for Semiconductors,” codified at ORS 315.518 through 315.522. This credit is available for tax years beginning on or after January 1, 2024, through December 31, 2029.

This new credit differs from its predecessors in three major ways:

• Industrial Specificity: It is limited to “qualified semiconductor companies”.
• Increased Rate: The credit rate was increased from 5 percent to 15 percent of the excess of qualified expenses over the base amount.
• Refundability: It introduced a partial refundability mechanism for smaller firms that may not have enough tax liability to use the full credit.

Comparison of Federal and Oregon Semiconductor Credit Provisions

Local Revenue Office Guidance: The Certification Process

The administration of the Oregon research credit is split between two distinct entities: Business Oregon (the state’s economic development agency) and the Oregon Department of Revenue (DOR). Taxpayers must successfully navigate the protocols of both to claim the credit.

Certification through Business Oregon

Under OAR Chapter 123, Division 401, Business Oregon is responsible for certifying that a company and its research activities meet the statutory requirements. This is a prerequisite; without certification, a taxpayer cannot claim the credit on their return.

Application Timelines and Deadlines

Taxpayers seeking the credit for the 2024 tax year were required to submit a one-time registration form by December 1, 2023. For the 2025 through 2029 tax years, taxpayers must file a written application for certification by October 15 of the calendar year in which the tax year begins. For example, a calendar-year corporation seeking a 2025 credit had an October 15, 2025, deadline.

Application Requirements

The application for certification (Form 150-102-130) must be submitted with a non-refundable $3,000 fee. The application must include:

• A narrative description proving the taxpayer is a “qualified semiconductor company”.
• A description of how the proposed R&D activities support a business directly related to semiconductors.
• Reports of QREs and basic research payments from the three preceding tax years.
• An attestation of the expected QREs and basic research payments in Oregon for the credit year.

Aggregate Statewide Caps

Because the credit is subject to an aggregate statewide cap, Business Oregon may proportionally reduce certified amounts if total applications exceed the limits.

Filing with the Oregon Department of Revenue (DOR)

Once the taxpayer receives their certification, they must claim the credit on their Oregon tax return. For C-Corporations, this is done on Form OR-20; for S-Corporations and Partnerships, the credit is calculated at the entity level and passed through to owners.

Schedule OR-RESEARCH

Taxpayers must attach Schedule OR-RESEARCH to their return. This schedule is used to calculate the credit amount based on either the Regular method or the Alternative Simplified Credit (ASC) method. The DOR provides explicit guidance that the IRC Section 41(c)(4) ASC method may be elected for Oregon purposes regardless of the federal election, but once made, it is generally irrevocable.

Oregon-Specific Definitions for Calculations

In applying the federal rules of IRC 41, Oregon administrative rules (OAR 150-315-0195) provide specific interpretations:

• “Gross Receipts”: Federal Section 41(c) refers to gross receipts. For Oregon, this means the total sales of the taxpayer in the state of Oregon, calculated using the numerator of the Oregon sales factor under ORS 314.665.
• “Qualified Research Expenses”: This is limited solely to research conducted in Oregon. This means even if a company is headquartered in Oregon, if the R&D lab is in Washington or California, those wages and supplies are excluded from the Oregon credit.

Analysis of the Refundability Mechanism

The most significant pro-growth feature of the new semiconductor credit is its partial refundability. This addresses a common criticism of R&D credits: that they only help established, profitable companies.

Refundability Tiers based on Oregon Employment

The amount of the credit that can be refunded to the taxpayer (as opposed to just offsetting tax liability) depends on the size of the company’s Oregon workforce.

The non-refundable portion can be carried forward for five years to offset future Oregon corporate excise or income tax liability. Notably, the refundable portion can also be used to satisfy the Oregon corporate minimum tax under ORS 317.090, which ranges from $150 to $100,000 based on Oregon sales.

Legislative Outlook: The 2025 Efforts for General Restoration

While the semiconductor credit is currently the only active R&D credit in Oregon, the 2025 legislative session saw a major push to reinstate a general credit for all industries.

House Bill 2117 (2025)

Introduced in January 2025, HB 2117 aimed to restore the general corporate research credit that had expired in 2017. This bill was more aggressive than the previous versions, proposing:

• An increase in the maximum credit from $1 million to $2 million.
• Full refundability and transferability of credits, allowing non-profitable startups to sell their credits to other taxpayers for cash.
• State-level decoupling from federal Section 174, allowing Oregon businesses to fully deduct R&D expenses in the year they were incurred rather than amortizing them.

Outcome of HB 2117 (2025): The 2025 session was marked by significant tension over tax policy. Republicans argued for these incentives to combat affordability issues and support local businesses. However, the session ended on June 27, 2025, without passing HB 2117. The bill remained in the House Committee on Revenue upon adjournment, meaning the status quo of a semiconductor-only credit remains in effect.

Comprehensive Example: Semiconductor Credit Calculation

To demonstrate how the interplay of IRC 41 and ORS 315.518 functions in practice, consider the following case study of an Oregon semiconductor design firm.

Case Study: Silicon River Design, LLC

Silicon River Design (SRD) is a Hillsboro-based company with 200 employees in Oregon. It specializes in the design of next-generation logic gates for mobile processors. In 2025, the company incurred the following expenses:

• Total Oregon QREs: $10,000,000 (Wages for chip designers, prototype fabrication costs)
• Average Oregon QREs (2022-2024): $6,000,000
• Oregon Sales (2025): $40,000,000
• Prior 4-Year Average Oregon Sales: $30,000,000
• Oregon Corporate Excise Tax Liability: $300,000

Certification

SRD must apply to Business Oregon by October 15, 2025. They pay the $3,000 fee and provide their 3-year history. Business Oregon reviews the application and certifies SRD for the credit because they meet the “qualified semiconductor company” definition and the research is conducted in Oregon.

Method Election (Regular vs. ASC)

SRD calculates the credit under both methods allowed by IRC 41 and OAR 150-315-0195.

The Regular Method:

The credit is 15% of Oregon QREs in excess of a base amount. The base amount is the product of the “fixed-base percentage” (assume 10%) and the average Oregon sales for the prior four years.

Base Amount = 10% x $30,000,000 = $3,000,000

Credit = 15% x ($10,000,000 – $3,000,000) = 15% x $7,000,000 = $1,050,000

The ASC Method:

The credit is 14% of Oregon QREs that exceed 50% of the average Oregon QREs for the three preceding years.

ASC Base = 50% x $6,000,000 = $3,000,000

ASC Credit = 14% x ($10,000,000 – $3,000,000) = 14% x $7,000,000 = $980,000

SRD elects the Regular Method to maximize their credit at $1,050,000.

Refundability and Application

Because SRD has 200 employees, they fall into the 50% refundability tier.

• Refundable Portion: 50% x $1,050,000 = $525,000
• Non-Refundable Portion: 50% x $1,050,000 = $525,000

SRD has an Oregon tax liability of $300,000.

• Apply the non-refundable portion ($525,000) up to the liability ($300,000). The tax liability is now $0.
• The remaining non-refundable portion ($225,000) is carried forward for up to 5 years.
• The refundable portion ($525,000) is issued as a check to SRD.

Administrative Compliance and Substantiation

Peer-level guidance for tax professionals emphasizes that the “Four-Part Test” is the most frequent point of failure in audits. For the Oregon semiconductor credit, the Department of Revenue will scrutinize whether the research was actually “conducted in Oregon” and whether it was “semiconductor-related”.

Documentation Best Practices

Taxpayers should maintain a “Nexus Folder” for each R&D project, containing:

• Project Plans: Documents outlining the technical uncertainty and the hypotheses being tested.
• Lab Notes and Photographs: Evidence of the systematic process of experimentation.
• Time Tracking: Detailed logs for employees whose wages are included, differentiating between “direct conduct” and “direct support”.
• Contract Agreements: For contract research, documentation must show the taxpayer assumes the “economic risk” regardless of the research outcome.

Common Pitfalls and Exclusions

Under Section 41(d)(4) and Oregon rules, several activities are strictly excluded from the credit:

• Post-Commercial Production: Any research conducted after the business component has been developed and is being sold to customers.
• Customization/Adaptation: Adapting an existing product to a specific customer’s requirements (unless it involves new technological uncertainty).
• Routine Quality Control: Standard testing and inspection of materials or products.
• Funded Research: Any research for which the taxpayer is being reimbursed by another person or governmental entity.

Strategic Implications of Oregon’s “Static Tie” to the IRC

Oregon tax law generally operates under a “Static Tie” date, meaning it follows the federal tax code as it existed on a specific date (currently December 31, 2023, for most corporate programs). This is critical because it means that even if the federal government were to retroactively repeal Section 174 amortization or change the Section 41 credit rate, those changes would not automatically apply to Oregon until the state legislature passed a “tie-in” bill.

This creates a risk of “decoupling,” where a company might have different QRE totals for federal and state purposes. For example, if the federal government allowed for immediate expensing of R&D in 2025 but Oregon did not (as seen in the failure of HB 2117), a company would have to maintain two sets of R&D records to track the different depreciation and amortization schedules.

Synthesis and Final Thoughts

The intersection of IRC Section 41 and the Oregon Research and Development Tax Credit for Semiconductors represents a sophisticated, policy-driven alignment intended to secure Oregon’s role in the global technology supply chain. By incorporating the rigorous federal Four-Part Test, the state ensures that only genuine innovation is subsidized, while its local modifications—specifically the 15 percent rate and tiered refundability—make it one of the most attractive incentives in the nation for semiconductor firms.

However, the administrative burden is high. The requirement for annual certification by Business Oregon, the strictly observed October 15 deadline, and the geographic limitation to “research conducted in Oregon” necessitate precise accounting and contemporaneous documentation. While the 2025 legislative push for a broader, refundable, and transferable general credit failed to materialize, the ongoing dialogue suggests that R&D incentives will remain a cornerstone of Oregon’s economic development strategy through the 2029 sunset of the current semiconductor program. Tax professionals must therefore remain vigilant regarding both federal Section 174 developments and state-level legislative changes to ensure their clients maximize these high-value opportunities while minimizing audit exposure.
