Qualified Research Expenditures (QREs)

Qualified Research Expenditures in Oklahoma represent the specific costs incurred during technological development—primarily wages, supplies, and contract research—that occur within state borders and qualify under federal Internal Revenue Code Section 41. These expenditures serve as the foundational metric for state-level financial incentives, including the current five percent research rebate program and historical job-creation tax credits.

The legal and administrative landscape for research and development (R&D) in Oklahoma has undergone a significant transformation, shifting from a focus on job expansion to a direct subsidization of technological investment. For decades, the state utilized a system of tax credits centered on the Oklahoma Investment/New Jobs Credit, governed by 68 O.S. § 2357.4, which rewarded capital investment in manufacturing and processing facilities. Parallel to this, Oklahoma maintained a specific Credit for Research and Development (codified at 68 O.S. § 54006), which utilized a “new jobs” model to incentivize high-tech employment in sectors such as computer services, data processing, and commercial research. However, as part of a broader effort to modernize economic incentives and compete with the aggressive rebate-style programs of neighboring states, the Oklahoma Legislature transitioned toward an expenditure-based model. The repeal of the previous R&D job credit in 2014 paved the way for the Oklahoma Research and Development Rebate Program, established via Senate Bill 324 and codified at 74 O.S. § 5091. This modern framework aligns Oklahoma’s definition of Qualified Research Expenditures (QREs) directly with federal standards found in Internal Revenue Code (IRC) § 41, providing a more predictable and administratively consistent path for businesses to recoup a portion of their innovation costs.

Statutory Framework and the Definition of Qualified Research Expenditures

The core of Oklahoma’s current R&D incentive structure is anchored in the “nexus” between state law and federal tax definitions. Under the provisions of 74 O.S. § 5091, the state has adopted a streamlined approach to defining eligible costs, thereby reducing the compliance burden on multi-state corporations that already calculate research credits at the federal level.

The Federal Nexus: Adoption of IRC § 41 Standards

For the purposes of the Oklahoma Research and Development Program, the term “Qualified Research Expenditures” is explicitly linked to the amounts reported on federal Form 6765, Credit for Increasing Research Activities. Specifically, the law identifies QREs as the expenses claimed on Line 9 or Line 28 of the December 2023 revision of Form 6765 (or the corresponding lines in subsequent revisions) that are attributable to activities conducted within the State of Oklahoma. This definition includes four primary categories of costs, as detailed in IRC § 41(b).

This adoption of federal standards implies that any expenditure that fails to meet the federal “four-part test” for qualified research is also ineligible for the Oklahoma rebate. These four parts require that the research be undertaken to discover information that is technological in nature, intended to resolve a technical uncertainty, conducted through a process of experimentation, and aimed at developing a new or improved business component.

Geographic and Temporal Limitations

While Oklahoma utilizes the federal definition of what types of costs are qualified, it imposes a strict geographic restriction: the expenditures must have “occurred in this state.” This necessitates a granular accounting of payroll and supply chains. For example, if a software engineer resides in Tulsa but performs work for a project led by a California-based headquarters, their wages may be included in the Oklahoma calculation only if they are subject to Oklahoma income tax withholding and the research activity itself is centered in an Oklahoma establishment.

Furthermore, the timing of these expenditures is critical. For the 2025 program year, the Oklahoma Department of Commerce accepts applications until December 31, 2025, for expenditures that occurred in the most recent tax year. This alignment with the tax year ensures that the state can verify the QREs against the federal Form 6765 filed with the taxpayer’s federal return.

Historical Context: The Repealed R&D New Jobs Credit

To understand the current administrative guidance from the Oklahoma Tax Commission (OTC), it is necessary to examine the “Research and Development New Jobs Credit” that existed under 68 O.S. § 54006. This credit, though now repealed for new activities, continues to influence the state’s tax environment through carryover provisions and the definitions of qualified sectors.

Eligible Entities and Industry Classifications

The historical credit was targeted at entities primarily engaged in “computer services, data processing or research and development” as defined by specific Standard Industrial Classification (SIC) codes. These codes served as the gatekeeper for research-related incentives for over two decades.

A unique requirement for these entities was the “out-of-state revenue” rule. To qualify, an entity had to derive at least 50% of its revenues from out-of-state buyers or consumers. This policy was designed to transform Oklahoma into an “export-oriented” hub for technology, ensuring that the state’s tax subsidies were supporting businesses that brought new capital into the local economy. This 50% threshold remains a relevant benchmark for many economic development incentives currently administered by the state.

The “New Jobs” Calculation Mechanism

Unlike the modern rebate, the prior R&D credit was valued at $500 per new employee. The “Qualified Research Expenditure” in this context was effectively the cost of hiring and maintaining high-wage labor. Employees had to be paid at least $35,000 annually and be “actually engaged in computer services, data processing, research and development, or the support thereof.”

Administrative guidance found in Form 563 and OAC 710:50-15-105 clarified that support personnel did not include general administrative, legal, accounting, clerical, or sales staff. This rigorous definition of “support” forced companies to separate their innovation-focused workforce from their general operations, a practice that remains essential for modern QRE wage allocation. Although a moratorium on claiming these jobs existed for activities between July 1, 2010, and June 30, 2012, the carryover rules allowed unused credits to be utilized for up to nine years (the initial four-year period plus a five-year extension).

The Oklahoma Research and Development Rebate Program (SB 324)

The enactment of SB 324 (2025) represents the current pinnacle of Oklahoma’s R&D strategy. This program, administered by the Oklahoma Department of Commerce rather than the Tax Commission, provides a direct five percent rebate for QREs.

Program Administration and the Rebate Fund

The law creates the “Oklahoma Research and Development Rebate Fund” in the State Treasury. This fund is designated as a continuing, revolving fund, meaning it is not subject to fiscal year limitations; however, its ability to pay out claims is entirely dependent on legislative appropriations. If the fund is not capitalized by the legislature in a given year, applications are still accepted and evaluated, but payments are held in a queue.

This “first-come, first-served” mechanism creates a high-stakes administrative environment for Oklahoma businesses. Companies that delay their application until later in the year risk being pushed to a subsequent fiscal year’s budget if the $20 million cap is reached. This dynamic incentivizes contemporaneous documentation and rapid filing as soon as federal tax returns are completed.

Eligibility Requirements for the Rebate

To be considered for a rebate payment, an “establishment” must satisfy three primary hurdles as defined in 74 O.S. § 5091(E):

• Application and Documentation: The entity must submit an online application to the Department of Commerce, including a copy of the federal Form 6765 that was filed with its tax return.
• In-State Verification: The entity must provide documentation proving that the research activities actually occurred within Oklahoma. This typically involves payroll summaries tied to Oklahoma-based EINs and invoices for supplies delivered to Oklahoma research facilities.
• Tax Compliance: The entity must be in good standing with the Oklahoma Tax Commission and have filed all required Oklahoma tax returns.

The “establishment” is typically defined as a single business unit or location where research is conducted. For corporations with multiple Oklahoma sites, this may require filing separate applications if those sites function as distinct establishments under the Department of Commerce’s rules.

The Role of the Oklahoma Tax Commission and Local Guidance

While the Department of Commerce handles the R&D rebate, the Oklahoma Tax Commission (OTC) remains the primary authority for ensuring that these incentives do not conflict with the state’s broader revenue laws. The OTC provides several layers of guidance through administrative rules, letter rulings, and form instructions.

Revocation of Obsolete Rules and Permanent Rulemaking

The OTC has recently proposed the revocation of OAC 710:50-15-105, which previously governed the R&D Job Credit. This move is purely administrative, reflecting the fact that the underlying statute (68 O.S. § 54006) was repealed by the legislature. For taxpayers, this signifies that the “old” job-based R&D credit is no longer available for new activities, and the focus for research-based incentives has moved entirely to the Department of Commerce’s rebate program and the Investment/New Jobs Credit under 68 O.S. § 2357.4.

However, the OTC continues to manage the “Investment/New Jobs Credit” via Rule 710:50-15-74. This rule is vital for R&D-intensive manufacturers because it covers the depreciable assets used in research, which are explicitly excluded from the QRE definition for the rebate.

Letter Ruling 24-003 and the “Three-Prong Test”

The OTC often clarifies the interaction between various incentives through letter rulings. A significant 2024 ruling (LR-24-003) addressed a manufacturer’s eligibility for the Investment/New Jobs Credit while also receiving Quality Jobs program incentive payments. The ruling noted that 68 O.S. § 3607 generally prohibits claiming both incentives for the same activity unless a specific “3-prong test” is met:

• The establishment must qualify for the Investment/New Jobs Tax Credit based on an investment made after January 1, 2010.
• The establishment must pay an average annualized wage that equals or exceeds the average state wage as determined by the Department of Commerce.
• The establishment must obtain a determination letter from the Department of Commerce stating that the business activity will result in a “positive net benefit rate” for the state.

This ruling is highly relevant for R&D projects. If a company invests $40 million in a new laboratory (qualified depreciable property), it may attempt to claim the Investment Credit. However, if that laboratory is also generating high-wage research jobs that qualify for Quality Jobs rebates, the company must carefully navigate this three-prong test to avoid the “double-dipping” prohibition.

Deep Dive into Component Costs: Wages, Supplies, and Support

The calculation of QREs is a highly technical exercise that requires an understanding of how Oklahoma interprets federal labor and supply definitions.

Qualified Research Wages and the “Substantially All” Rule

For the Oklahoma rebate, “qualified research wages” are those paid to employees for “qualified services.” The administrative guidance from the federal level, adopted by the state, identifies three tiers of research services:

• Direct Conduct: The actual performance of experimentation or research (e.g., an Oklahoma-based engineer designing a new prototype).
• Direct Supervision: First-line management of the research process. If a research director in Oklahoma City manages a team of bench scientists, their time spent on that management is a qualified wage.
• Direct Support: Services that facilitate the research, such as a lab assistant in Tulsa preparing materials for an experiment or a machinist in Stillwater building a prototype.

Oklahoma follows the “substantially all” rule (the 80/20 rule). If an individual employee performs qualified services for at least 80% of their time during the taxable year, 100% of their wages may be included as a QRE. Conversely, if they spend less than 80% of their time on research, only the actual percentage of their wages tied to research may be included.

Qualified Supplies and the Depreciation Exclusion

A critical distinction in Oklahoma law is the treatment of tangible property. Under IRC § 41(b)(2)(C), “supplies” are defined as any tangible property other than land, improvements to land, and property of a character subject to the allowance for depreciation.

This creates a binary choice for Oklahoma taxpayers. If an item used in R&D is non-depreciable (like chemicals, test-tubes, or prototype materials that are consumed), it is a QRE and qualifies for the 5% rebate. If the item is depreciable (like a high-tech microscope or a robotic arm used in research), it is not a QRE for the rebate program but may instead qualify for the 1%-2% Investment/New Jobs Credit under 68 O.S. § 2357.4.

Utility Costs and Extraordinary Expenditures

In general, administrative guidance treats utility costs (water, electricity, gas) as general administrative expenses, which are excluded from QREs. However, a nuanced exception exists for “extraordinary expenditures.” If an Oklahoma research facility can demonstrate that a specific experiment required significantly higher-than-normal utility usage—such as a data center running high-intensity simulations or a cold-room facility used for biological research—those “extraordinary” portions of the utility bill may be treated as qualified research supplies.

Specialized Research Incentives in the Aerospace Sector

The aerospace industry is a cornerstone of the Oklahoma economy and receives specialized treatment that overlays the general R&D incentive structure.

Aerospace Industry Engineer Workforce Tax Credits

Under 68 O.S. §§ 2357.301-304, aerospace companies hiring engineers can receive an income tax credit equal to 5% of the compensation paid to the engineer (or 10% if the engineer graduated from an Oklahoma university), capped at $12,500 per year per employee.

For R&D-heavy aerospace firms, the wages of these engineers often qualify as QREs for the state rebate. However, because the aerospace credits are income tax credits (claimed on Form 565 or 511-CR) and the R&D incentive is a rebate, businesses must coordinate with their tax advisors to ensure that the claiming of the aerospace credit does not reduce the “un-reimbursed” portion of the wage for rebate purposes.

ABET Accreditation and “Qualified Programs”

Administrative guidance for the aerospace credit (Form 564) emphasizes the role of the Accreditation Board for Engineering and Technology (ABET). To qualify for the aerospace credits, an engineer must have graduated from a “qualified program”—meaning a program that was ABET-accredited on the date the taxpayer graduated. While this specific accreditation is not a strict requirement for the general R&D rebate, it is a key differentiator for companies looking to maximize their total incentive package in the aerospace sector.

Specialized R&D Credits: Biomedical and Cancer Research

Oklahoma also provides targeted incentives for research in the healthcare sector, particularly through 68 O.S. § 2357.45, which encourages donations to qualified cancer and biomedical research institutes.

The 50% Donation Credit

This credit allows any Oklahoma taxpayer who makes a charitable contribution to a qualified cancer research institute (such as the Stephenson Cancer Center) or a biomedical research institute (such as the Oklahoma Medical Research Foundation) to claim a tax credit equal to 50% of the donation. The credit is capped at $1,000 for individuals or $2,000 for a married couple filing jointly.

Unlike the R&D rebate, which targets performing the research, this credit targets funding the research through non-profit entities. Guidance from the Stephenson Cancer Center and OMRF clarifies that a “cancer research institute” must be a tax-exempt organization whose primary focus is raising the standard of clinical care through peer-reviewed research and education.

Administrative Reporting for Donation Credits

Taxpayers must report these credits on Form 511-CR (Other Credits). Guidance for the 2024 tax year requires taxpayers to enter the credit amount on Line 15 and provide a copy of the canceled check or a receipt from the foundation as proof of the donation. If the Biomedical Research Contribution is the only credit claimed, taxpayers are instructed to enter “15” in the box on Line 17; otherwise, they enter “99” to indicate multiple credits.

Procedural Filing and Documentation Standards

Success in claiming Oklahoma R&D incentives depends heavily on following the correct filing procedures and maintaining audit-ready documentation.

The Role of Form 511-CR

Form 511-CR is the primary vehicle for claiming income tax credits in Oklahoma. It aggregates various credits, including the Investment/New Jobs Credit, the Aerospace credits, and the Cancer Research credits.

The instructions for Form 511-CR clarify that taxpayers must enter in “Column B” all credits established in the current tax year. This includes:

• Credits generated in the current year.
• Credits transferred to the taxpayer on a filed transfer agreement (Form 572).
• Subsequent years’ portions of established credits (like the 5-year Investment Credit).

For the R&D Rebate, however, the process is distinct. Because it is a rebate administered by the Department of Commerce, it is not claimed on Form 511-CR. Instead, the “tax credit shall be exclusively claimed through the submission of an application” and cannot be used to directly offset income tax liability on a return. This makes it a “cash-back” program rather than a tax reduction program.

Documentation for In-State QREs

The Oklahoma Department of Commerce and the OTC require contemporaneous records to support research claims. Recommended documentation includes:

• Project Logs: Narratives explaining the technical uncertainty and the process of experimentation for each project.
• Payroll Records: Documentation showing that wages were subject to Oklahoma withholding and were paid for qualified services.
• Supply Ledgers: Invoices for tangible property consumed in Oklahoma research, with proof of non-depreciable status.
• Federal Form 6765: A complete copy of the federal return showing the total R&D credit calculation.

The 2024 federal redesign of Form 6765, which introduced Section G for detailed business component reporting, is expected to be a primary tool for Oklahoma auditors to verify that the research activity meets the four-part test.

Fiscal and Economic Implications: The $20 Million Cap

The most significant constraint on the Oklahoma R&D Rebate Program is the $20 million annual cap and the requirement for legislative appropriation.

Proration and Subsequent Year Payments

Under 74 O.S. § 5091(G), if the total approved claims exceed the balance of the R&D Rebate Fund or the $20 million fiscal year limit, the Department of Commerce may issue payments in a prorated amount. Claims that are not paid due to these limitations may be “approved and paid in subsequent fiscal years.”

This creates a “queue” of approved but unfunded claims. For a business, this means that while the 5% rebate is established in law, the timing of the cash receipt is uncertain. This uncertainty is a critical factor in financial modeling for R&D projects in Oklahoma.

Comparison with Quality Jobs Program

In contrast to the R&D Rebate, the Quality Jobs Program (68 O.S. § 3601 et seq.) typically has more stable funding mechanisms and provides quarterly cash rebates of up to 5% of new taxable payroll for up to 10 years. Large manufacturers must decide whether to pursue the long-term payroll rebate of Quality Jobs or the immediate R&D rebate for innovation-specific expenditures.

Comprehensive Illustrative Example: Stratos Innovation Corp

To demonstrate the complex interaction of these rules, consider the case of Stratos Innovation Corp, a fictional aerospace startup located in Tulsa, Oklahoma.

Company Profile and Activity

In 2024, Stratos Innovation Corp:

• Purchased $1,000,000 of specialized manufacturing and testing equipment (depreciable property).
• Hired 10 new aerospace engineers, all graduated from ABET-accredited programs at Oklahoma State University.
• Paid $1,500,000 in wages to these engineers, who spent 100% of their time developing a new autonomous flight control algorithm.
• Spent $200,000 on non-depreciable supplies (electronic components and specialized testing gases) consumed during the project.
• Paid $100,000 to an Oklahoma-based software firm for contract testing of the algorithm (Stratos retains all rights).

Step 1: Calculating Qualified Research Expenditures (QREs)

The company first identifies its in-state QREs for the Oklahoma R&D Rebate Program:

• Wages: $1,500,000 (qualifies because engineers are in Oklahoma and performing qualified services).
• Supplies: $200,000 (qualifies as non-depreciable property consumed in research).
• Contract Research: $65,000 (65% of the $100,000 contract).
• Equipment: $0 (excluded as it is depreciable property).

Total Oklahoma QREs: $1,765,000.

Step 2: Calculating the R&D Rebate

Applying the 5% rate from 74 O.S. § 5091:

• Rebate Amount: $1,765,000 × 0.05 = $88,250.

Stratos applies for this rebate through the Department of Commerce by December 31, 2025.

Step 3: Calculating Other Credits (Form 511-CR)

Simultaneously, the company utilizes the Oklahoma Tax Commission’s income tax credits for its other costs:

• Investment Credit (68 O.S. § 2357.4): The $1,000,000 in equipment qualifies for the Investment Credit. As a manufacturer, Stratos claims 1% of the cost in the first year: $10,000.
• Aerospace Engineer Credit (68 O.S. § 2357.303): For the 10 Oklahoma graduate engineers, the company can claim 10% of their compensation, capped at $12,500 per engineer.

• $1,500,000 / 10 = $150,000 per engineer.
• 10% of $150,000 = $15,000 (which exceeds the $12,500 cap).
• Total Aerospace Credit: 10 engineers × $12,500 = $125,000.

Step 4: Compliance and Interaction

Stratos must ensure it does not violate the “double-dipping” rules if it also applies for Quality Jobs. If Stratos receives Quality Jobs payments for these 10 engineers, it must meet the “3-prong test”—paying above the state average wage and proving a positive net benefit to Oklahoma—to keep its $10,000 Investment Credit. However, the R&D Rebate and the Aerospace Credits are generally considered distinct incentives for high-tech innovation and can often be claimed in tandem, provided each program’s specific documentation requirements are met.

Future Outlook: Legislative and Administrative Trends

The Oklahoma R&D landscape remains dynamic, with ongoing efforts to stabilize funding and clarify definitions.

Sunset Provisions and Extensions

Many Oklahoma tax credits are subject to sunset provisions. For example, the aerospace sector income tax credits were recently extended from tax year 2025 to tax year 2031 via SB 287. This long-term extension provides the stability necessary for the aerospace industry to commit to long-duration R&D projects.

The Role of Governor Stitt’s “Limiting Government” Initiative

Recent veto messages from Governor Stitt (e.g., SB 208 and HB 1030) indicate a commitment to streamlining state boards and reducing “unnecessary licenses” and hurdles for businesses. This philosophy may eventually impact R&D administration, potentially leading to a more consolidated approach to economic incentives where the Department of Commerce and the Tax Commission share a more integrated digital portal for all business credits and rebates.

Impact of Global and National Shifts in R&D Policy

Oklahoma’s adoption of the IRC § 41 definition means that state policy is inherently reactive to federal changes. For instance, the federal requirement to amortize R&D expenses under Section 174 (rather than deducting them immediately) has significantly increased the “taxable income” of research firms. This makes the Oklahoma 5% rebate even more critical, as it provides a cash inflow to offset the increased federal tax burden caused by amortization.

Final Thoughts

Qualified Research Expenditures in Oklahoma are the essential building blocks of the state’s innovation economy. By tethering state definitions to the federal Form 6765, Oklahoma has created a high-fidelity incentive system that rewards in-state scientific and technological experimentation. While the transition from the old job-based R&D credit to the current 5% rebate program has simplified the definition of QREs, it has also introduced new administrative layers, such as the Department of Commerce application process and the $20 million fiscal year cap.

For professional peers and corporate practitioners, the key to maximizing these incentives lies in a rigorous bifurcation of costs: identifying non-depreciable supplies and wages for the R&D rebate, while simultaneously capturing depreciable assets through the Investment/New Jobs Credit and specialized sectors through aerospace-specific incentives. As Oklahoma’s fiscal environment evolves, the meticulous maintenance of contemporaneous, in-state documentation will remain the “gold standard” for ensuring that every dollar of qualified research activity is fully leveraged under the law.
