IRC Section 174

Internal Revenue Code Section 174 governs the federal timing for deducting research and experimental costs, either allowing immediate relief or requiring multi-year capitalization. Because Oregon is a rolling conformity state, these federal timing shifts directly modify Oregon taxable income, making the federal classification of research and experimental (R&E) costs the primary driver of state tax liability and credit eligibility.

The Conceptual and Historical Foundation of IRC Section 174

Internal Revenue Code (IRC) Section 174, originally enacted in 1954, represents a fundamental policy lever intended to stimulate American innovation by simplifying the tax accounting treatment of research and experimental expenditures. Before its enactment, taxpayers faced significant uncertainty regarding whether research costs should be treated as ordinary business expenses under Section 162 or capitalized as assets with indeterminate useful lives. Section 174 resolved this by providing an elective framework: taxpayers could either currently deduct expenditures in the year paid or incurred or treat them as deferred expenses to be amortized over a period of not less than 60 months. This flexibility stood as a cornerstone of the federal tax code for nearly seven decades, particularly benefiting small businesses and startups that required immediate cash flow to fund continued scientific and engineering activities.

The definition of research and experimental expenditures under Section 174 is broader than the “qualified research” defined for credit purposes under Section 41. Under Treasury Regulation Section 1.174-2(a)(1), R&E expenditures are costs incurred in connection with a taxpayer’s trade or business that represent research and development costs in the “experimental or laboratory sense.” This encompasses activities intended to discover information that would eliminate uncertainty concerning the development or improvement of a product, process, formula, invention, or technique. Uncertainty exists if the information available to the taxpayer does not establish the capability of development, the methodology of development, or the appropriate design of the product.

The 2017 Tax Cuts and Jobs Act (TCJA) Paradigm Shift

The landscape of innovation taxation was radically altered by the Tax Cuts and Jobs Act (TCJA) of 2017. While the bill was passed in 2017, the changes to Section 174 were deferred until tax years beginning after December 31, 2021. The TCJA eliminated the option for immediate expensing, mandating that all R&E expenditures be capitalized and amortized. Specifically, domestic research expenditures were required to be amortized over a five-year period (using a mid-year convention), while research conducted outside the United States was subject to a fifteen-year amortization schedule.

This transition created a significant “tax cliff” for R&D-intensive companies. In the first year of implementation (2022), a company spending $1 million on domestic R&D that previously deducted the full amount was now limited to a $100,000 deduction (10% of the total due to the half-year convention). This effectively increased taxable income by $900,000 in the initial year, creating substantial cash-flow challenges for firms regardless of their actual profitability.

Restoration of Expensing: The One Big Beautiful Bill Act (OBBBA) of 2025

Following years of bipartisan concern regarding the impact of the TCJA amortization rules, the One Big Beautiful Bill Act (OBBBA) was signed into law on July 4, 2025. The OBBBA fundamentally restored the immediate deductibility of domestic R&E expenditures by creating a new IRC Section 174A. Effective for tax years beginning after December 31, 2024, Section 174A allows taxpayers to fully deduct domestic research costs in the year paid or incurred. Notably, the OBBBA did not rescind the 15-year amortization requirement for foreign R&E, maintaining a legislative strategy aimed at incentivizing the “on-shoring” of technical talent and infrastructure.

Oregon’s Legal Framework: Rolling Conformity and Statutory Nexus

Oregon’s tax code is inextricably linked to the federal Internal Revenue Code through the principle of conformity. Oregon is categorized as a “rolling conformity” state for provisions that impact the definition of federal taxable income (FTI). Under ORS 317.010 and related statutes, the state automatically adopts any federal changes to the IRC as they are amended and in effect for the taxpayer’s tax year, provided those changes relate to the measurement of income.

The Mechanics of Oregon Conformity

Because the timing of deductions under Section 174 and Section 174A directly affects the calculation of FTI, Oregon automatically follows these federal rules. When the TCJA required capitalization in 2022, Oregon did not enact legislation to decouple; thus, Oregon taxpayers were required to capitalize their R&D costs for state purposes. Conversely, with the passage of the OBBBA and the creation of Section 174A, Oregon conforms to the restoration of immediate expensing for domestic R&D for tax years beginning in 2025.

During the 2025 legislative session, the Oregon Legislature considered House Bill 2092, which would have updated the state’s static conformity date and potentially disconnected the state from rolling conformity for certain 2025 updates. However, this bill failed to pass, solidifying Oregon’s alignment with the OBBBA’s Section 174A expensing for the 2025 tax year and beyond.

Detailed Analysis of the Oregon R&D Tax Credit (ORS 315.518)

Oregon offers a specialized research and development tax credit primarily aimed at the semiconductor industry, which was re-established by House Bill 2009 in 2023. This credit, codified as ORS 315.518, provides a meaningful offset to state tax liability for “qualified semiconductor companies” conducting research in Oregon.

Eligibility Criteria and “Qualified Semiconductor Company” Status

Eligibility for the Oregon credit is more restrictive than the federal Section 41 credit. A taxpayer must be a “qualified semiconductor company,” defined as an entity whose primary business is the research, design, development, fabrication, assembly, testing, packaging, or validation of semiconductors. This also includes companies creating semiconductor manufacturing equipment, core intellectual property, or specialized materials.

Furthermore, the research must be:

1. Conducted in Oregon: Unlike the federal credit, which covers all U.S.-based research, Oregon’s credit is strictly limited to activities performed within state borders.
2. Technological in Nature: The research must meet the federal “four-part test” under IRC Section 41(d).

Credit Calculation Methods

Oregon allows taxpayers to use either the “Regular Method” or the “Alternative Simplified Credit” (ASC) method to calculate their credit.

The Regular Method (ORS 315.518)

The regular method provides a credit equal to 15% of the “excess” qualified research expenses over a base amount. The base amount is calculated using the taxpayer’s historical Oregon R&D intensity and average Oregon sales for the prior four years.

The Alternative Simplified Credit (ASC)

Taxpayers can elect the ASC method on Schedule OR-RESEARCH. This method is often preferred by companies that lack the historical records required for the regular method or whose R&D spending has fluctuated.

• Standard ASC: 14% of the amount by which current-year Oregon QREs exceed 50% of the average Oregon QREs for the three preceding tax years.
• Modified ASC: If the taxpayer has no Oregon QREs in any of the three preceding years, the credit is 6% of the current year’s Oregon QREs.

Refundability and Headcount Tiers (ORS 315.519)

A distinguishing feature of the Oregon semiconductor credit is its tiered refundability. For taxpayers with fewer than 3,000 employees in Oregon, the credit can be partially refunded if it exceeds the taxpayer’s liability for the year.

1. 75% Refundable: For companies with fewer than 150 Oregon employees.
2. 50% Refundable: For companies with 150 to 499 Oregon employees.
3. 25% Refundable: For companies with 500 to 2,999 Oregon employees.
4. Non-refundable: For companies with 3,000 or more Oregon employees.

Any non-refundable portion of the credit can be carried forward for up to five years.

Administrative Guidance and Local Revenue Office Procedures

The Oregon Department of Revenue (DOR) and Business Oregon (the Oregon Business Development Department) share responsibility for administering R&D incentives. Claiming the semiconductor credit is a two-step process requiring both state-level certification and tax return reporting.

Step 1: Certification through Business Oregon

Taxpayers cannot simply claim the credit on their return; they must obtain an annual certification from Business Oregon.

• Application Deadline: October 15 of the calendar year in which the tax year begins. For example, a calendar-year taxpayer for 2025 must have applied by October 15, 2025.
• Fees: An application fee—currently $3,000—is required for each certification request.
• Aggregate Statewide Cap: Oregon limits the total amount of credits certified to all taxpayers. For 2025, the cap was $38.25 million, part of an $80 million biennium allocation. If the program is oversubscribed, Business Oregon may prorate credits over $200,000 to fit within the cap.

Step 2: Reporting to the Oregon Department of Revenue

Once certified, the taxpayer claims the credit on their corporate excise tax return (Form OR-20) or personal income tax return (Form OR-40).

• Schedule OR-RESEARCH (Form 150-102-130): This schedule must be attached to the return to calculate the credit and report the certification number.
• Documentation Retention: Oregon Law (ORS 315.061) allows the DOR to audit and revoke credits for noncompliance. Taxpayers should maintain project-level records, including technical narratives, time-tracking data for engineers, and supply invoices for at least four years.

Interaction Between Section 174 and Section 280C

A critical point of interaction occurs regarding the prevention of “double dipping”—receiving both a deduction and a credit for the same expense. This is managed through IRC Section 280C(c).

Federal Reduced Credit Election (280C)

Normally, under Section 280C(c)(1), a taxpayer must reduce their Section 174 deduction (or capitalize less) by the amount of the R&D credit. Alternatively, taxpayers can elect a “reduced credit” on federal Form 6765. The reduced credit is equal to the gross credit minus the credit multiplied by the maximum corporate tax rate (currently 21%).

Oregon Application of 280C

Because Oregon’s taxable income starts with FTI, any reduction in the federal deduction due to 280C automatically increases Oregon taxable income. Furthermore, ORS 317.152(5) explicitly states that “a deduction may not be taken for the portion of expenses… that is equal to the amount of the credit claimed under this section.”

This creates a “cascading effect”:

1. Federal Impact: Taxpayer either takes a full deduction and 21%-reduced credit, or full credit and reduced deduction.
2. Oregon Impact: Oregon follows the federal deduction result. If the taxpayer reduces their federal deduction, they have more Oregon income. If they elect the reduced federal credit, they preserve their full state-level deduction.

Special Considerations for Software Development

Software development costs are specifically addressed in Section 174 and have undergone significant shifts in treatment.

The Definition of Software Development

Under the TCJA and the subsequent OBBBA (Section 174A(c)(3)), any amount paid or incurred in connection with the development of any software is treated as an R&E expenditure. This includes:

• Planning, design, and model building.
• Coding and testing up to the point of internal deployment or external sale of product masters.

It generally excludes routine maintenance, bug fixes after commercial release, and quality control during production.

Software for Oregon Purposes

In Oregon, software companies must distinguish between development (subject to 174/174A) and general operating expenses. With the restoration of expensing in 2025, Oregon companies can once again deduct domestic software development costs immediately. However, if a Portland-based firm outsources its coding to a developer in India, those “foreign R&E” costs must still be capitalized and amortized over 15 years for both federal and Oregon purposes.

Small Business Relief and Retroactive Implementation

The OBBBA provides unique “retroactivity” options for small business taxpayers that were burdened by the 2022-2024 capitalization requirements.

Eligibility for Retroactivity

To be eligible for the retroactive application of Section 174A (immediate expensing) for the 2022, 2023, and 2024 tax years, a taxpayer must meet the Section 448(c) gross receipts test. For 2025, this generally means average annual gross receipts for the three preceding years of $31 million or less. Additionally, the taxpayer must not be a “tax shelter” (e.g., a partnership allocating more than 35% of losses to limited partners).

Implementation Methods in Oregon

Small businesses that qualify can use one of two methods to recognize these “caught up” deductions:

1. Amended Return Method: Small businesses may amend their 2022 and 2023 federal and Oregon returns to claim the immediate deduction. This requires filing Oregon Form OR-20-X or an amended personal return.
2. Accounting Method Change (Section 481(a) Adjustment): Alternatively, a taxpayer can file Form 3115 with their 2024 return. This allows for a “catch-up” adjustment that accelerates all unamortized domestic R&D into the 2024 tax year. Because Oregon conforms to federal accounting methods, this deduction flows through to the Oregon return, often creating or increasing a state Net Operating Loss (NOL).

Economic Implications: The “Kicker” and Revenue Forecasts

The treatment of Section 174 has direct consequences for Oregon’s unique “kicker” surplus rebate program. Oregon law requires that if actual state revenues exceed the forecast by more than 2%, the surplus must be returned to taxpayers.

The TCJA Impact on State Surpluses

The mandatory capitalization of R&D from 2022 to 2024 artificially inflated Oregon’s corporate and individual tax revenues by deferring deductions. This contributed to the massive $1.41 billion personal income tax kicker and the $921.6 million corporate surplus reported by the Office of Economic Analysis (OEA) in September 2025.

The OBBBA Impact on Future Revenues

The restoration of expensing under Section 174A in 2025 is expected to reduce Oregon’s General Fund revenue. The September 2025 OEA forecast estimated that the OBBBA’s corporate and personal provisions would result in an $888 million reduction in state revenue for the 2025-2027 biennium. Specifically, the ability for small businesses to amend prior returns (2022-2024) to claim R&D refunds is a primary driver of this anticipated downward adjustment.

Comprehensive Example: Oregon Technology Solutions (OTS)

To synthesize these concepts, consider “Oregon Technology Solutions (OTS),” a Portland-based C-corporation that designs specialized microchips.

OTS Financial Profile (2025)

• Gross Receipts (3-yr Avg): $15,000,000 (Qualifies as Small Business).
• Total Domestic R&E (2025): $2,000,000.
• Unamortized R&D from 2022-2024: $1,500,000.
• Oregon-Sourced QREs (2025): $1,200,000.
• Average Oregon QREs (2022-2024): $800,000.
• Oregon Employees: 85 (Qualifies for 75% refundability).

Step 1: Section 174A Expensing and 481(a) Adjustment

OTS elects to retroactively apply Section 174A using the accounting method change path on its 2024 return.

• 2025 Deduction (Current): $2,000,000 (Full expensing under 174A).
• 2025 Deduction (Catch-up): OTS claims a $1,500,000 Section 481(a) adjustment on its Oregon return, representing the domestic R&D it was forced to capitalize in 2022-2024.
• Total Oregon Deduction: $3,500,000.

Step 2: Oregon Semiconductor Credit Calculation (ASC Method)

OTS elects the ASC method on Oregon Schedule OR-RESEARCH.

1. Calculate Base: 50% of 3-year average ($800,000) = $400,000.
2. Calculate Excess: $1,200,000 (current) – $400,000 (base) = $800,000.
3. Calculate Credit: 14% of $800,000 = $112,000.

Step 3: Interaction and 280C Coordination

OTS elects the “Reduced Credit” under Section 280C(c)(2) for federal purposes to preserve its full deduction.

• Oregon Add-back: Under ORS 317.152(5), OTS must reduce its Oregon deduction by the amount of the state credit claimed ($112,000).
• Net Oregon Taxable Income Impact: The $3,500,000 deduction is reduced to $3,388,000.

Step 4: Refundability and Cash Flow

Assume OTS has an Oregon tax liability of $50,000 before the credit.

1. Liability Offset: The credit first eliminates the $50,000 tax due.
2. Excess Credit: $112,000 – $50,000 = $62,000.
3. Refund Amount: Because OTS has 85 employees, it is in the 75% refund tier.

• $62,000 x 75% = $46,500 cash refund.
• The remaining $15,500 (25%) is carried forward to 2026.

Summary of Oregon-Specific Guidance Points

For practitioners managing Oregon R&D tax compliance, the following localized rules are paramount:

• Certification First: No Oregon credit can be claimed without an October 15 certification from Business Oregon.
• The “Oregon-Only” Rule: Only wages, supplies, and contract research physically performed in Oregon qualify.
• Rolling Conformity: Oregon follows federal Section 174A immediately; no separate state expensing election is required for corporations.
• Refundability is Linked to Headcount: Accurate Oregon employee counts are essential to determine whether the credit is non-refundable, 25%, 50%, or 75% refundable.
• Federal Audit Protection: Oregon DOR closely follows IRS audit findings. If the IRS disallows a Section 174 expense, Oregon will likely disallow the corresponding deduction and credit.

The legislative restoration of domestic R&D expensing in 2025 provides a significant tailwind for the Oregon technology sector. By aligning state tax policy with federal innovation incentives, Oregon maintains its position as a competitive environment for advanced manufacturing and software development. However, the complexity of managing certification deadlines, multi-year amortization schedules for foreign R&D, and the nuances of state-to-federal conformity requires a rigorous and proactive approach to tax planning.
