Applicable Percentage (15%)

Theoretical and Statutory Foundations of the 15% Credit Rate

The emergence of the 15% applicable percentage in Oregon’s tax code represents a calculated shift in the state’s industrial policy, moving away from broad-based incentives toward a precision-targeted support system for the semiconductor sector. Under Oregon Revised Statutes (ORS) 315.518, the “applicable percentage” is defined as the specific rate used to determine the value of a tax credit allowed against personal income or corporate excise taxes. This percentage is explicitly set as a modification to the federal percentage specified in Section 41(a) of the Internal Revenue Code (IRC), which historically sits at 20% for the Regular Research Credit (RRC). By setting the state rate at 15%, Oregon provides one of the highest state-level R&D incentives in the United States, tripling the 5% rate that characterized the state’s general R&D tax credit before its expiration in 2017.

The legal mechanism for this credit was established by House Bill 2009 in the 2023 legislative session, a response to both the federal CHIPS and Science Act and a perceived need to maintain Oregon’s competitive edge in the “Silicon Forest”. The 15% rate is not applied to a company’s total research expenditure; rather, it is applied to the “incremental” or “excess” amount of qualified research expenses (QREs). This distinction is critical: the law does not subsidize baseline operations but specifically rewards growth in research investment. The 15% multiplier acts as a subsidy on the margin, designed to influence the internal rate of return (IRR) for capital-intensive projects such as the design of new integrated circuit architectures or the development of advanced lithography techniques.

Administrative Guidance from the Department of Revenue and Business Oregon

The practical application of the 15% rate is governed by a dual-agency administrative framework involving the Oregon Department of Revenue (DOR) and the Oregon Business Development Department (Business Oregon). While the DOR manages the tax filing and audit process, Business Oregon is responsible for the certification of “qualified semiconductor companies”.

The Role of Business Oregon in Rate Verification

Before a taxpayer can apply the 15% percentage on their tax return, they must obtain an annual certification from Business Oregon. This certification process serves as a gatekeeper to ensure that the 15% rate is only utilized by entities whose primary business is intrinsically linked to the semiconductor ecosystem. Guidance provided by the agency indicates that applicants must submit a detailed narrative describing how their proposed research and development activities support a trade or business directly related to semiconductors, including design, fabrication, and testing.

The administrative guidance for the 2025 tax year emphasizes that the certification process is competitive and subject to statewide aggregate caps. For the biennium beginning July 1, 2023, the total amount of tax credits available for all semiconductor companies was capped at $35 million, with subsequent biennial increases. If the sum of all certified 15% credit claims exceeds the statewide cap, Business Oregon has the authority to prorate the credits, meaning the “realized” percentage for a taxpayer could technically fall below 15% if the program is oversubscribed.

Department of Revenue Interpretations and OAR 150-315-0195

The Oregon Department of Revenue provides technical guidance through Administrative Rules, specifically OAR 150-315-0195, which clarifies the interaction between the state credit and the federal Internal Revenue Code. A significant point of guidance within this rule is the definition of “gross receipts” for the purpose of calculating the base amount. Oregon deviates from the federal definition of national gross receipts, instead requiring taxpayers to use their Oregon sales factor as defined in ORS 314.665. This ensures that the 15% credit is scaled to the company’s economic footprint specifically within Oregon.

Furthermore, the DOR guidance clarifies that while the statutory 15% rate applies to the Regular Research Credit method, taxpayers may elect the Alternative Simplified Credit (ASC) method under IRC §41(c)(4). However, if the ASC method is chosen, the 15% rate from ORS 315.518(2)(a) is supplanted by the percentages specified in the federal ASC method, which are 14% for established researchers or 6% for those with no research history in the preceding three years.

Calculation Method	Statutory Rate Reference	Applicable Percentage	Base Amount Logic
Regular Research Credit (RRC)	ORS 315.518(2)(a)	15%	Fixed-base % × 4-yr average Oregon sales
Alternative Simplified (ASC)	OAR 150-315-0195(3)	14%	50% of 3-yr average Oregon QREs
ASC (No prior QREs)	OAR 150-315-0195(3)	6%	No base amount (applied to total current QREs)

Qualifications and Scope of the Semiconductor Research Nexus

To prevent the dilution of the 15% incentive, the law restricts its application to research that is both geographically and industrially specific. This “nexus” requirement is a central pillar of local revenue office guidance.

Defining the Qualified Semiconductor Company

The 15% rate is reserved for “qualified semiconductor companies,” a term that includes more than just silicon wafer manufacturers. Local guidance expands this to include firms engaged in the creation of semiconductor manufacturing equipment, core intellectual property (IP), and electronic design automation (EDA) software. The rationale behind this broad definition is to capture the entire value chain, recognizing that advances in EDA software are as critical to the 15% credit’s goal of “regaining America’s technological leadership” as physical fabrication.

Geographic Sourcing of Research Expenses

A defining characteristic of Oregon’s guidance is the strict sourcing of expenses. The 15% applicable percentage is only applied to expenses incurred for research conducted “within the state of Oregon”. This differs from the federal credit, which allows for research across all U.S. states. Consequently, companies must maintain rigorous accounting of wages, supplies, and contract research payments specifically tied to Oregon-based facilities. For instance, a design engineer’s wages are only eligible if the employee is physically performing the research in Oregon.

The Four-Part Test for Qualified Research

Both the state and federal revenue offices require that activities meet the “Four-Part Test” to be eligible for the 15% credit. This test ensures that the research is truly innovative and not merely routine engineering or aesthetic design:

• Technological in Nature: The activity must rely on principles of physical science, biological science, engineering, or computer science.
• Permitted Purpose: The research must be intended to develop a new or improved business component’s function, performance, reliability, or quality.
• Elimination of Uncertainty: The taxpayer must demonstrate they intended to discover information to eliminate technical uncertainty regarding the development or improvement of a product.
• Process of Experimentation: The activity must involve a systematic trial-and-error process, such as modeling, simulation, or prototyping.

For semiconductor companies, this might involve the development of a series of prototypes to achieve specific technical objectives, such as reducing power consumption in a microprocessor or increasing the signal-to-noise ratio in a sensor.

Mechanics of the 15% Rate Calculation

The calculation of the Oregon semiconductor credit is an incremental process that builds upon the foundational logic of the federal R&D tax credit. The 15% applicable percentage is the final step in a multi-layered arithmetic progression.

The Regular Research Credit (RRC) Calculation

Under the RRC method, the 15% percentage is applied to the difference between current-year QREs and a base amount. The formula for this “base amount” is particularly complex as it involves a “fixed-base percentage”—a historical ratio of research spend to gross receipts—multiplied by the company’s average Oregon gross receipts for the prior four tax years.

The steps for calculating the credit under this method include:

1. Determine Total Oregon QREs: Sum of wages, supplies, and 65% of contract research payments for semiconductor-related research in Oregon.
2. Determine Average Oregon Gross Receipts: The average of Oregon-sourced sales for the four years preceding the current tax year.
3. Calculate the Base Amount: Multiply the fixed-base percentage (which is capped at 16%) by the average Oregon gross receipts.
4. Identify Excess QREs: Subtract the base amount from the current-year Oregon QREs.
5. Apply the 15% Rate: Multiply the excess QREs by 0.15.

Basic Research Payment Credit

A separate calculation is performed for basic research payments—typically contributions to universities for fundamental research that does not have a specific commercial objective. The 15% rate is also applied to these payments, but the base amount is determined under IRC §41(e), which compares current payments to a historical “base period amount”.

The Strategic Importance of Refundability and Tiered Benefits

Perhaps the most significant aspect of the Oregon semiconductor credit, apart from the 15% rate itself, is its refundability mechanism. This feature is a direct response to the long development cycles and high capital requirements of the semiconductor industry, which often lead to periods where a company has significant research expenses but no taxable income to offset.

Refundability Tiers Based on Workforce Size

The 15% credit is partially refundable for companies with fewer than 3,000 employees in Oregon. The percentage of the credit that is refundable decreases as the company’s headcount increases, a design intended to provide the most aggressive support to smaller innovators while still offering substantial benefits to large-scale employers.

Oregon Employee Headcount	Refundable Portion of Credit	Non-refundable Portion (Carryforward)
< 150 Employees	75%	25%
150 – 499 Employees	50%	50%
500 – 2,999 Employees	25%	75%
3,000+ Employees	0%	100%

Any portion of the 15% credit that is not refundable can be carried forward for five succeeding tax years to offset future Oregon tax liability. This tiered structure provides immediate cash flow (in the form of a tax refund) to smaller firms, which can be reinvested in further research or used to hire additional specialized engineers.

Interaction with the Corporate Minimum Tax

In a significant piece of local revenue office guidance, the DOR clarifies that the refundable portion of the semiconductor credit can be used to satisfy the Oregon corporate minimum tax under ORS 317.090. Typically, Oregon credits cannot be used to reduce the tax below the minimum, but the semiconductor credit is a rare exception for the refundable portion, further increasing the effective value of the 15% rate for low-liability taxpayers.

Comprehensive Calculation Example: Silicon Design & Fab, LLC

To understand how the 15% applicable percentage translates into actual tax savings, consider the case of “Silicon Design & Fab, LLC,” a company with 200 employees in Oregon.

Scenario Background and Financial Data

• Current Year (2024) Oregon QREs: $10,000,000
• Average Oregon Gross Receipts (Prior 4 Years): $50,000,000
• Fixed-Base Percentage: 10.00% (or 0.10)
• Qualified Basic Research Payments: $100,000
• Base Period Amount for Basic Research: $0 (First-time participant)
• Pre-Credit Tax Liability: $200,000

Step-by-Step Credit Determination

Part I: Incremental QRE Credit

1. Determine Base Amount: $50,000,000 (Average Receipts) × 0.10 (Fixed-Base %) = $5,000,000.
2. Calculate Excess QREs: $10,000,000 (Current) – $5,000,000 (Base) = $5,000,000.
3. Apply 15% Rate: $5,000,000 × 0.15 = $750,000.

Part II: Basic Research Credit

1. Calculate Excess Payments: $100,000 – $0 = $100,000.
2. Apply 15% Rate: $100,000 × 0.15 = $15,000.

Part III: Total Credit and Application

1. Total Calculated Credit: $750,000 + $15,000 = $765,000.
2. Individual Taxpayer Cap Check: The total of $765,000 is well below the $4 million annual cap per taxpayer.
3. Liability Offset: $765,000 – $200,000 (Liability) = $565,000 remaining credit.
4. Refundability Calculation: Because the company has 200 employees, it falls in the 50% refundability tier.
5. Determine Refund and Carryforward:

• Refundable Amount: $565,000 × 0.50 = $282,500 (Issued as cash refund).
• Non-Refundable Carryforward: $565,000 × 0.50 = $282,500 (To be used over the next 5 years).

In this example, the 15% applicable percentage results in a total benefit of $765,000, providing the company with $282,500 in immediate cash liquidity while completely eliminating its current-year tax burden.

Filing Procedures and Compliance Requirements

Securing the benefits of the 15% credit rate requires strict adherence to a multi-stage procedural timeline. Failure to comply with any single step can lead to the forfeiture of the credit, regardless of the quality of the research conducted.

Certification and the October 15th Deadline

Taxpayers intending to claim the 15% credit must submit an annual application for certification to Business Oregon no later than October 15th of the calendar year in which the tax year begins. This application must include:

• Proof of Eligibility: Documentation proving the company meets the definition of a “qualified semiconductor company”.
• Expense Projections: A detailed report of QREs from the three preceding tax years and a projection for the current tax year.
• Application Fee: For the 2025 cycle, the fee is set at $3,000.

Schedule OR-RESEARCH and Form OR-20

Once certified by Business Oregon, the credit is claimed on the taxpayer’s Oregon return using Schedule OR-RESEARCH (Form 150-102-130). This schedule requires the taxpayer to list their FEIN, legal name, and the number of Oregon employees at year-end, as this headcount directly determines the refundability of the 15% credit. The certified amount from Business Oregon must be entered on the tax return, and any unused non-refundable portion must be tracked across future years using the “Carryforward” lines of the schedule.

Audit Risks and Documentation Standards

Given the high value of the 15% rate, the Oregon Department of Revenue maintains strict audit standards for semiconductor R&D claims. Taxpayers are advised to retain business records for at least four years, documenting every aspect of the research process. According to industry guidance, essential documentation includes:

• Project Plans and Progress Reports: Evidence of the systematic process of experimentation.
• Literature Reviews: Documentation of existing technical knowledge and the specific uncertainties the research intended to overcome.
• Test Results and Analysis: Data from prototypes and simulations that justify the R&D expenditure.

Comparative Context: Oregon vs. Global and National Benchmarks

The 15% applicable percentage is best understood when compared to the broader landscape of R&D incentives. Oregon’s decision to provide a 15% rate specifically for semiconductors is part of a global race to secure intellectual property and manufacturing capacity.

Incentive Program	Base Rate	Specific Focus	Refundability?
Oregon Semiconductor R&D	15%	Semiconductors only	Yes (Tiered)
Federal R&D Credit (RRC)	20%	All industries	No (General) / Yes (Startups)
California R&D Credit	15%	All industries	No
Arizona R&D Credit	24%	All industries	Yes (SMEs)
Massachusetts R&D Credit	10%	All industries	No

While some states like Arizona offer a higher headline rate (24% on the first $2.5 million), Oregon’s 15% rate is highly competitive because it does not have the aggressive tiering that reduces the rate for larger expenditures until the $4 million cap is reached. Furthermore, the specific focus on semiconductors in Oregon allows for a more streamlined regulatory environment compared to the broad and often contested definitions found in general state R&D credits.

Fiscal Projections and Economic Outlook

The 15% credit rate is expected to have a significant impact on Oregon’s state revenue and its economic development trajectory. Analysis by the Legislative Revenue Office (LRO) provides insight into the scale of the program during its initial years.

Initial Participation and Revenue Impact

In the first registration cycle, approximately 26 taxpayers registered for the credit, projecting roughly $600 million in qualified research expenditures for the 2024 tax year. The average QREs for these companies over the prior three years was estimated at $500 million, indicating a significant growth trend that the 15% credit is designed to support. For the fiscal year 2024-25, the total estimated revenue loss to the state is projected at $23.9 million, well within the $35 million biennium cap.

The 2029 Sunset and Future Viability

The semiconductor R&D credit, including its 15% rate, is currently scheduled to “sunset” or expire on December 31, 2029. This expiration date forces a future legislative review of the credit’s effectiveness. Policymakers will likely evaluate whether the 15% multiplier succeeded in increasing the statewide volume of research and whether the “Silicon Forest” maintained its leadership position during the period of the credit’s availability.

Final Thoughts

The 15% applicable percentage is more than a simple tax rate; it is a fundamental component of Oregon’s economic identity in the 21st century. By tripling the previous state credit rate and aligning it with the specific technical and financial needs of the semiconductor industry, Oregon has created a robust tool for regional growth. The integration of federal IRC definitions with Oregon-specific sales factors and tiered refundability ensures that the credit is both technically sound and economically impactful. For professional tax practitioners and corporate strategists, maximizing the benefit of the 15% rate requires a comprehensive approach that bridges the gap between engineering documentation and tax compliance, ensuring that every dollar of incremental Oregon research is accurately captured and certified under the state’s ambitious semiconductor agenda.
