Fixed-Base Percentage (Prior Credit)

Statutory Framework and the Evolution of Oregon Research Incentives

The Oregon Qualified Research Activities tax credit, primarily governed by Oregon Revised Statute (ORS) 317.152, represents a significant pillar of the state’s economic development strategy aimed at fostering innovation. At its core, the credit is designed to be incremental, meaning it does not reward a company’s total research spending but rather the increase in spending over a determined historical baseline. This baseline is fundamentally anchored by the “Fixed-Base Percentage,” a term borrowed from federal tax law under Internal Revenue Code (IRC) §41, which Oregon has adopted with specific local modifications.

Historically, the Oregon Research and Development (R&D) tax credit was available to all corporations conducting qualified research within the state from its enactment in 1989 until its sunset on December 31, 2017. Although the broad credit has expired, the mechanics of the “Prior Credit”—a term often used by the Oregon Department of Revenue to refer to this pre-2018 incentive—remain critical for two reasons: first, the extensive five-year carryforward period allows corporations to use credits generated before 2018 to offset current tax liabilities; and second, the recently enacted Semiconductor R&D tax credit (HB 2009) utilizes nearly identical calculation methodologies, including the Fixed-Base Percentage, albeit with higher rates and stricter industry focus.

The Revenue Impact of the Sunset Provision

The decision to allow the broad R&D credit to sunset in 2017 was influenced by legislative evaluations of its efficacy. According to the Oregon Legislative Revenue Office (LRO), in 2014 alone, 376 corporations claimed a total of $85.6 million in tax credits, yet only $15.2 million was actually utilized to reduce tax liability in that period. This discrepancy highlights the complexity of the credit’s application and the restrictive nature of the “base amount” requirements. Despite the sunset, the revenue impact remains substantial due to carryforwards, as shown in the table below:

Biennium	Corporate Revenue Impact	Personal Revenue Impact	Total Revenue Impact
2013–15	$14,300,000	Not Applicable	$14,300,000
2015–17	$15,100,000	$5,000,000	$20,100,000
2017–19	$14,800,000	$3,300,000	$18,100,000
2019–21	$20,500,000	$400,000	$20,900,000
2021–23	$12,000,000	$100,000	$12,100,000

Conceptualizing the Fixed-Base Percentage

The Fixed-Base Percentage (FBP) is the variable that scales the “base amount” relative to a company’s revenue growth. Under ORS 317.152 and Oregon Administrative Rule (OAR) 150-315-0195, the FBP is computed using the guidelines established in IRC §41(c)(3) and §41(f)(4). It is defined as the ratio of a taxpayer’s qualified research expenses (QREs) to its gross receipts during a specific historical period.

The Oregon Department of Revenue mandates that this percentage be rounded to four decimal places (e.g., 0.0333 or 3.3333%) and capped at a maximum of 16 percent. This cap prevents the base amount from becoming so high that it renders the credit unreachable for firms with exceptionally high research intensity during their base years.

Dual Paths for Determination: Existing vs. Startup Firms

The law distinguishes between “existing” corporations and “startup” corporations to ensure fairness for companies that were not in existence during the mid-1980s.

Existing Corporations

An existing corporation is defined as one that had both gross receipts and qualified research expenses in at least three tax years during the period beginning after December 31, 1983, and before January 1, 1989. For these entities, the Fixed-Base Percentage is “fixed” by their performance in that mid-80s window. It is calculated by dividing the aggregate QREs for those tax years by the aggregate gross receipts for those same years.

Startup Corporations

A corporation is treated as a startup if its first taxable year with both gross receipts and QREs occurred after 1983, or if it did not have at least three years of such activity during the 1984–1988 base period. To support these emerging companies, Oregon adopts a phased-in approach for the FBP. For the first five years a startup company has QREs, the FBP is automatically set at 3 percent. Starting in the sixth year, the FBP begins to reflect a weighted average of the company’s actual historical spending, as detailed in the following table:

Tax Year with QREs	Formula for Fixed-Base Percentage
Years 1–5	Fixed at 3.0000%
Year 6	1/6 of (Aggregate QREs for Years 4–5 / Aggregate Gross Receipts for Years 4–5)
Year 7	1/3 of (Aggregate QREs for Years 5–6 / Aggregate Gross Receipts for Years 5–6)
Year 8	1/2 of (Aggregate QREs for Years 5–7 / Aggregate Gross Receipts for Years 5–7)
Year 9	2/3 of (Aggregate QREs for Years 5–8 / Aggregate Gross Receipts for Years 5–8)
Year 10	5/6 of (Aggregate QREs for Years 5–9 / Aggregate Gross Receipts for Years 5–9)
Years 11+	Actual ratio of QREs to Gross Receipts for any 5-year period between Years 5–10

Calculation of the Base Amount

The Fixed-Base Percentage is not the credit itself; rather, it is used to calculate the “base amount,” which represents the threshold of non-creditable R&D activity. The base amount is the product of the FBP and the average annual gross receipts of the taxpayer for the four taxable years preceding the credit year.

Base Amount = FBP × Average Gross Receipts (Prior 4 Years)

However, there is a critical “floor” or minimum base amount rule. The law stipulates that the base amount cannot be less than 50 percent of the qualified research expenses for the current tax year. This prevents the credit from subsidizing more than half of a firm’s current R&D efforts, regardless of how much their research spending has grown relative to their historical base.

Defining Gross Receipts and the Oregon Modification

A significant point of local guidance from the Oregon Department of Revenue concerns the definition of “gross receipts.” While federal law uses a broad definition, Oregon requires the use of the Oregon sales factor as defined in ORS 314.665. This modification is vital because it ensures the credit is proportionate to the taxpayer’s business footprint within the state. If a multi-state corporation has $100 million in global sales but only $10 million in Oregon sales, the “base amount” is calculated using the $10 million figure, making the credit more accessible for companies focusing their research efforts in Oregon.

Qualified Research Expenses: The Numerator of the Ratio

To determine the Fixed-Base Percentage, a corporation must accurately identify its Qualified Research Expenses (QREs). Oregon law follows the federal “Four-Part Test” to qualify an activity as research:

1. Section 174 Test: The expenditures must be deductible as research and experimental costs.
2. Technological Information Test: The research must be undertaken to discover information that is technological in nature.
3. Business Component Test: The research must be intended to be useful in the development of a new or improved business component.
4. Process of Experimentation Test: Substantially all of the activities must constitute a process of experimentation relating to a new or improved function, performance, reliability, or quality.

The state allows three primary categories of costs to be included in QREs, provided they are paid or incurred in Oregon:

Category	Inclusion Details
Wages	Salaries of employees directly involved in R&D, as well as those directly supervising or supporting them.
Supplies	Tangible property used in the research process, excluding land and improvements to real property.
Contract Research	65% of the amounts paid to third parties for research conducted on the taxpayer’s behalf in Oregon.

Administrative Guidance and Documentation Requirements

The Oregon Department of Revenue (DOR) provides specific instructions on Schedule OR-RESEARCH (formerly Part II of the R&D credit form) for reporting the Fixed-Base Percentage. Taxpayers must enter the percentage on Line 5, ensuring it does not exceed the 16 percent statutory limit.

The Consistency Requirement

DOR guidance emphasizes the “consistency requirement” under IRC §41(c)(5) and OAR 150-315-0195. This rule dictates that the QREs used to calculate the current year’s credit must be determined in a manner consistent with the QREs used in the base period. For example, if a company includes certain overhead wages in its current-year QREs, it must retroactively include those same types of wages in its 1984–1988 (or startup) base period QREs. This prevents taxpayers from artificially inflating their credit by “changing the rules” of what counts as R&D after the base period has been set.

Verification and Certification

Under the “Prior Credit” (broad credit), documentation had to be maintained for at least four years, although federal rules often necessitate keeping 1980s base period records indefinitely to defend the FBP in an audit. For the new 2024 Semiconductor R&D credit, the process is more rigorous: taxpayers must register with Business Oregon and receive preliminary confirmation before claiming the credit on their tax return.

Administrative Step	Requirement Detail
Registration	Must register annually with Business Oregon (e.g., by Dec 1 for the 2024 credit).
Application Fee	A fee (typically $3,000) is required for certification of the semiconductor credit.
Reporting	Submit documentation of QREs and basic research expenses averaged over the three preceding years.
Certification	Business Oregon issues a confirmation of the credit amount, which is then entered on Schedule OR-RESEARCH.

Example: Calculating the Oregon R&D Credit using FBP

To clarify the application of the law, consider “Oregon Innovate Corp,” a qualified semiconductor company applying for the new 15 percent credit in 2025.

Step 1: Establish the Fixed-Base Percentage

Oregon Innovate Corp is an “existing” firm that has been in operation since 1980. Its records for the 1984–1988 base period show the following:

• Aggregate Oregon QREs (1984–1988): $2,000,000
• Aggregate Oregon Gross Receipts (1984–1988): $40,000,000

The Fixed-Base Percentage is calculated as:

FBP = $2,000,000 / $40,000,000 = 0.0500 or 5.0000%

Step 2: Determine Average Gross Receipts

The company looks at its Oregon sales for the four preceding years (2021–2024):

• 2021: $50,000,000
• 2022: $55,000,000
• 2023: $60,000,000
• 2024: $75,000,000
• Average Annual Gross Receipts: $60,000,000

Step 3: Calculate the Base Amount

Multiplying the FBP by the average gross receipts gives:

$60,000,000 × 5.0000% = $3,000,000

Step 4: Compare to 50% Floor

In 2025, the company incurs $10,000,000 in Oregon QREs. The law requires the base amount to be at least 50% of this figure:

$10,000,000 × 50% = $5,000,000

Since $5,000,000 is greater than $3,000,000, the Base Amount for the tax year is $5,000,000.

Step 5: Final Credit Calculation

The credit is 15 percent of the excess QREs over the base amount.

• Excess QREs: $10,000,000 – $5,000,000 = $5,000,000
• Tax Credit: $5,000,000 × 15% = $750,000

Note: If this were the “Prior Credit” (pre-2018), the rate would be 5%, resulting in a credit of $250,000.

Alternative Methodologies: The Alternative Simplified Credit (ASC)

Recognizing that many companies struggle to produce 1980s-era documentation, both federal and Oregon law provide an alternative: the Alternative Simplified Credit (ASC). Under the ASC method, the Fixed-Base Percentage and Gross Receipts are entirely ignored. Instead, the base amount is defined as 50 percent of the average Oregon QREs for the three preceding taxable years.

While the ASC method is generally easier to document, the credit rate is lower. Under the prior Oregon credit, the ASC rate was 5% (the same as the regular method), but the base amount calculation was often more favorable for companies with rapidly growing sales. However, for the new 2024 semiconductor credit, some industry experts note that while the 15% regular rate is attractive, the ASC method may be restricted or have different percentage tiers depending on current Department of Revenue administrative rules.

Policy Implications and Future Outlook

The “Prior Credit” (ORS 317.152) sunset in 2017 was a significant moment in Oregon tax history. Legislative analysts noted that the credit’s lack of refundability meant it provided little benefit to startups or businesses in loss positions—the very companies most likely to be conducting intensive R&D. This led to recommendations to make future credits, such as the semiconductor credit, partially refundable.

The current Semiconductor R&D credit (2024–2030) addresses many of the perceived failures of the prior broad credit by:

• Increasing the credit rate from 5% to 15%.
• Raising the per-taxpayer cap from $1 million to $4 million.
• Introducing partial refundability for companies with fewer than 3,000 employees.

Despite these improvements, the “Fixed-Base Percentage” remains the core mechanism for ensuring the state’s investment remains focused on incremental innovation. By requiring companies to surpass their own historical benchmarks, Oregon aims to incentivize new discoveries rather than subsidizing existing operations. For tax professionals and corporate officers, a nuanced understanding of the FBP—especially the distinction between existing and startup status and the strict 16% cap—is essential for optimizing tax positions and ensuring compliance with the Oregon Department of Revenue’s evolving guidance.
