Quick Answer: What are “Expenses Incurred in this State”?
“Expenses incurred in this state” refers to the specific subset of federal qualified research expenditures—such as wages, supplies, and contract research—that are physically performed or consumed within the geographic boundaries of Oklahoma. Under 74 O.S. § 5091, this geographic requirement is the primary eligibility filter for the Oklahoma Research and Development Rebate Program, distinct from the broader federal standard.
Expenses incurred in this state are the specific subset of federal qualified research expenditures, encompassing localized wages, supplies, and contract research services, that are physically performed or consumed within the geographic boundaries of Oklahoma. Under the statutory framework established by 74 O.S. § 5091, these expenditures serve as the five-percent basis for the state’s cash rebate program, provided they meet the rigorous four-part federal eligibility test.
The evolution of Oklahoma’s research and development (R&D) incentive landscape represents a fundamental shift from traditional tax liability reduction to a direct liquidity-based rebate system. For decades, the state utilized a variety of income tax credits and sales tax exemptions to attract high-tech investment, but the repeal of the primary R&D income tax credit in 2014 left a significant gap in the state’s economic development toolkit. The passage of Senate Bill 324 (SB 324) in 2025, which created the Oklahoma Research and Development Rebate Program, was intended to bridge this gap by offering a more accessible benefit to pre-profit startups and established innovation leaders alike. This report provides an exhaustive examination of the legal definitions, administrative requirements, and jurisdictional nuances governing the Oklahoma R&D rebate, with a specific focus on the operational meaning of expenses incurred within the state.
The Statutory Architecture of SB 324 and Title 74 Section 5091
The current legal standard for research incentives in Oklahoma is codified under Title 74 of the Oklahoma Statutes, a move that distinguishes the R&D rebate from traditional tax code provisions found in Title 68. Section 5091 creates a revolving fund known as the Oklahoma Research and Development Rebate Fund, which is managed not by the Tax Commission, but by the Oklahoma Department of Commerce. This administrative structure signals that the program is viewed primarily as an economic development grant rather than a standard tax deduction.
The statute defines “qualified research expenditures” by tethering the state’s eligibility criteria to the federal standard found in the Internal Revenue Code (IRC) Section 41. Specifically, the state looks to the amounts claimed on federal Form 6765, which is the “Credit for Increasing Research Activities.” However, the law imposes a strict geographic overlay: the rebate is only applicable to the portion of those federal expenses that were “incurred in this state.”
Historical Context and the Repeal of Prior Credit Regimes
To understand the current rebate program, one must analyze the policy vacuum that preceded it. Until 2013-2014, Oklahoma offered a state-based R&D income tax credit that was largely calculated based on the net increase in the number of full-time equivalent employees or investments in depreciable property. This credit, governed by OAC 710:50-15-105, was often tied to specific industrial group numbers in the Standard Industrial Classification (SIC) Manual, such as computer services or data processing.
The prior system required businesses to derive at least 50% of their revenues from out-of-state buyers and often mandated a minimum of $100,000 in computer-related equipment purchases. The transition to the new rebate program eliminates many of these legacy SIC restrictions in favor of the broader federal definition of “qualified research,” thereby opening the incentive to a wider range of industries, including aerospace, biotechnology, and advanced energy.
Core Comparison of Current and Former R&D Incentives
| Feature | Legacy R&D Income Tax Credit (Pre-2014) | 2025 R&D Rebate Program (SB 324) |
|---|---|---|
| Statutory Authority | 68 O.S. § 2357.4 / 68 O.S. § 54006 | 74 O.S. § 5091 |
| Payment Mechanism | Income Tax Credit (Reduction of Liability) | Cash Rebate (Direct Reimbursement) |
| Basis of Calculation | New Jobs or Depreciable Property | Federal QREs (Form 6765) |
| Rate | Variable ($500 per job or 1% of investment) | 5% of Qualified Expenditures |
| Geographic Limit | Oklahoma-based investment | “Incurred in this State” |
| Cap on Claims | Revenue reduction (Unlimited until sunset) | $20 Million Annual Fund Limit |
The Federal Nexus: Understanding IRC Section 41 and Form 6765
Since the Oklahoma rebate is calculated based on federal qualified research expenses (QREs), the definition of “expenses incurred in this state” must first satisfy the federal criteria for what constitutes “research.” The Internal Revenue Service (IRS) utilizes a four-part test to determine if an activity qualifies for the credit under IRC Section 41.
The Four-Part Test for Qualified Research
The first requirement is the “Section 174 Test,” which dictates that expenditures must be research and experimental costs in the experimental or laboratory sense. This includes all costs incident to the development or improvement of a product. Beyond this, the activity must meet the following:
- Technological in Nature: The research must rely on the principles of hard sciences, such as engineering, physics, chemistry, biology, or computer science.
- Permitted Purpose: The objective of the research must be to create a new or improved business component, which is defined as a product, process, software, technique, formula, or invention to be held for sale, lease, or license, or used in the taxpayer’s trade or business.
- Elimination of Uncertainty: The taxpayer must attempt to resolve uncertainty regarding the capability, method, or appropriate design of the business component.
- Process of Experimentation: Substantially all of the activities must constitute a process of experimentation, involving the evaluation of alternatives through modeling, simulation, or systematic trial and error.
Federal Categories of Qualified Expenses
Under IRC Section 41, the federal QRE is the sum of in-house research expenses and contract research expenses. In-house research expenses include:
- Wages: Amounts paid to employees for “qualified services,” which include engaging in qualified research or the direct supervision or support of research activities.
- Supplies: Amounts paid for tangible property (other than land or depreciable property) used in the conduct of qualified research.
- Computer Rental/Cloud Costs: Costs paid for the right to use computers for the conduct of qualified research.
For the Oklahoma rebate, the Department of Commerce specifically looks at lines 5, 20, or 48 of federal Form 6765 (depending on the tax year and revision) to find the baseline for the 5% calculation.
Analyzing the Geographical Mandate: “Incurred in this State”
While the federal code allows for expenses incurred anywhere in the United States, Oklahoma law restricts the rebate to expenses incurred specifically within the state. This jurisdictional boundary requires a detailed sourcing analysis for each category of expense. The Oklahoma Department of Commerce (ODOC) requires documentation to prove that the activity was physically conducted in Oklahoma.
Personnel Costs and the Remote Workforce
In the modern economic environment, the sourcing of wages is the most complex aspect of the “incurred in this state” requirement. For a wage to be eligible for the Oklahoma rebate, the service must be performed in Oklahoma. This means that if an Oklahoma-based corporation employs a software developer who works remotely from a home in Texas or Colorado, those wages are generally excluded from the Oklahoma rebate, even if they qualify for the federal R&D credit.
Conversely, the state applies the “80% rule” found in federal guidance: if at least 80% of an employee’s services are qualified research services, then 100% of their wages may be treated as QREs. However, the Oklahoma-specific caveat is that 100% of those services must also be performed within the state’s borders. To substantiate these claims, the Oklahoma Tax Commission (OTC) and ODOC may review payroll records, withholding statements (Form W-2), and time logs that correlate hours worked with project locations.
Supplies and Tangible Property Sourcing
For supplies to be “incurred in this state,” they must be utilized or consumed at an Oklahoma-based research facility. The state rejects claims for supplies that are purchased by an Oklahoma entity but shipped to out-of-state laboratories for testing. Documentation such as shipping invoices, bills of lading to Oklahoma addresses, and project-specific purchase orders are essential for proving that the “incurred” event—the consumption of the supply in the research process—took place locally.
Contract Research and Third-Party Engagements
Contract research expenses are generally includable at 65% of the amount paid to the third party. For these to be eligible for the Oklahoma rebate, the research must be performed in Oklahoma. This creates a significant hurdle for companies that outsource high-tech testing to national laboratories or coastal universities. If an Oklahoma energy company pays a contractor in California to conduct specialized seismic modeling, those costs do not meet the “incurred in this state” test.
The law encourages “in-state” collaboration by rewarding companies that utilize Oklahoma’s higher education system or local private labs. When a firm contracts with the University of Oklahoma or Oklahoma State University for qualified research, the 65% includable amount becomes a valid basis for the 5% state rebate.
Administrative Guidance: The Oklahoma Department of Commerce (ODOC)
The Department of Commerce is the lead agency for the R&D Rebate Program. Unlike the Tax Commission, which focuses on revenue collection, ODOC focuses on economic impacts. The agency has promulgated specific rules under OAC Title 150, Chapter 170 (and related guidelines) to manage the application and verification process.
The Application Lifecycle
The application process is entirely digital and follows a strict timeline. For the 2025 program year, ODOC began accepting applications on August 28, 2025. The submission window for the most recent tax year typically closes on December 31.
Key steps in the ODOC process include:
- Submission of Documentation: Applicants must provide a copy of their filed federal Form 6765.
- Nexus Verification: Applicants must provide documentation, as required by the Department, to determine that the expenditures occurred within the state.
- Evaluation of Completeness: Incomplete applications are granted a 15-business-day “cure period” to submit missing materials before being rejected in favor of subsequent applicants.
- Order of Approval: Claims are processed on a first-come, first-served basis.
The Notarized Attestation
A critical component of the guidance is the “Research and Development Rebate Program Attestation.” An authorized agent of the establishment must swear or affirm under penalty of perjury that the company is in good standing and that “the qualified research expenditures claimed in the application occurred in the State of Oklahoma.” This attestation serves as a legal safeguard, ensuring that the burden of geographic sourcing falls squarely on the taxpayer.
Regulatory Oversight: The Oklahoma Tax Commission (OTC)
While ODOC administers the rebate, the Oklahoma Tax Commission maintains oversight of the taxpayer’s compliance history. Eligibility is contingent upon the establishment being in “good standing” with the OTC.
Defining “Good Standing”
The term “good standing” is not merely a formality; it requires that the establishment has filed all Oklahoma tax returns as required by law. This includes:
- Corporate/Individual Income Tax: Filing the appropriate Form 511, 512, or 512-S.
- Withholding Tax: Ensuring all payroll taxes for Oklahoma-based researchers have been remitted.
- Sales and Use Tax: Compliance with reporting requirements, even if the entity is exempt from certain sales taxes.
If the Tax Commission identifies a failure to file or a significant outstanding liability, the Department of Commerce may withhold approval of the rebate until the issue is resolved. This ensures that the state does not issue cash rebates to entities that are simultaneously delinquent in their basic tax obligations.
Reporting the Rebate on Tax Returns
While the rebate is a cash payment, it may have implications for the taxpayer’s state income tax filing. Taxpayers who receive the federal R&D credit are required to report it on their state return if it impacts their state taxable income, particularly under IRC Section 280C, which prohibits a double benefit for the same expense (deduction plus credit).
Interplay with Other State Incentives
Oklahoma’s incentive framework is designed to be “stackable” in some cases but mutually exclusive in others. Understanding how the R&D rebate interacts with the Quality Jobs program and the Investment/New Jobs Credit is vital for strategic tax planning.
The Quality Jobs Program (68 O.S. § 3601)
The Quality Jobs program provides a cash rebate of up to 5% of new taxable payroll for up to 10 years. There is a general prohibition against claiming certain incentives for the same activity that receives Quality Jobs payments. However, Section 3607 of Title 68 provides an exception for companies that make a capital investment of at least $40 million.
For most R&D establishments, the Quality Jobs program and the R&D rebate can coexist if the establishment can demonstrate that the research activities (re-incentivized by the rebate) are distinct from the primary job creation activities (re-incentivized by the Quality Jobs program).
Investment/New Jobs Tax Credit (68 O.S. § 2357.4)
Commonly known as the “Manufacturer’s Credit,” this incentive allows for a five-year tax credit on the greater of 1% of investment in new depreciable property or $500 per new job. This credit doubles to 2% or $1,000 per job in Enterprise Zones or for investments exceeding $40 million.
The Investment Credit is claimed via Form 506 and reported on Form 511-CR. While the R&D rebate targets the operational expenses of research, the Investment Credit targets the capital infrastructure (machinery, buildings, equipment) used in manufacturing or research.
Comparison of Primary Oklahoma Business Incentives
| Program | Benefit Type | Basis | Primary Goal |
|---|---|---|---|
| R&D Rebate | Cash Rebate | 5% of in-state QREs | Encourage R&D spending |
| Quality Jobs | Cash Rebate | Up to 5% of new payroll | High-wage job creation |
| Invest./New Jobs | Tax Credit | 1% of assets / $500 per job | Capital expansion |
| Software/Cyber | Tax Credit | $1,800-$2,200 per employee | Specialized workforce growth |
Fiscal Mechanics: The $20 Million Cap and Appropriations
The most significant constraint on the Oklahoma R&D Rebate Program is its funding mechanism. Unlike a tax credit, which is essentially an “open-ended” reduction in state revenue, a rebate is an “expenditure” of state funds that must be appropriated by the legislature.
The Role of the Rebate Fund
Section 5091 creates the “Oklahoma Research and Development Rebate Fund” in the State Treasury. This fund is “revolving,” meaning it does not expire at the end of the fiscal year, and it consists of monies specifically appropriated for the program. However, the law explicitly states that “total claims approved for rebate shall not exceed Twenty Million Dollars ($20,000,000.00) in any fiscal year.”
Proration and Carryover Provisions
Because claims are paid in the order received, a “run on the fund” could occur if several large aerospace or energy companies apply simultaneously. To manage this, the statute provides two mechanisms:
- Proration: If a claim exceeds the available balance in the fund, the payment may be made in a prorated amount.
- Subsequent Year Approval: Claims not approved due to the $20 million limit may be approved and paid in subsequent fiscal years.
Current Funding Status (2025-2026)
As of late 2025, the Oklahoma Department of Commerce has issued a critical warning: while the program is established in law, the legislature has not yet appropriated funds to the Rebate Fund. There is “NO guarantee that funds will be appropriated.” Consequently, while applications are being accepted and evaluated for eligibility, no payments will be processed until the legislature takes action.
Detailed Mathematical Example: The Aerospace Innovation Scenario
To demonstrate the application of the “incurred in this state” principle, consider the case of “Vanguard Propulsion,” a fictional aerospace firm located in Oklahoma City. Vanguard is developing a new hydrogen-based engine for small unmanned aerial vehicles (UAVs).
Step 1: Identification of Federal QREs
For the 2025 tax year, Vanguard Propulsion files federal Form 6765 and identifies the following total research expenditures:
- Internal Wages: $4,000,000 (paid to 20 engineers).
- Research Supplies: $800,000 (titanium alloys, sensors, and fuel cells).
- Contract Research: $1,500,000 (paid to specialized testing firms).
- Total Federal QRE Basis: $6,300,000 (after applying the 65% contractor haircut).
Step 2: Sourcing “Incurred in this State”
Vanguard must now perform a geographic audit to identify Oklahoma-sourced expenses.
Wage Sourcing Analysis
The payroll records show that of the 20 engineers:
- 15 work at the Oklahoma City hangar (Total Wages: $3,000,000).
- 5 work remotely from California and Massachusetts (Total Wages: $1,000,000).
- Oklahoma In-State Wages: $3,000,000.
Supply Sourcing Analysis
The supply invoices show:
- $600,000 worth of materials were delivered to the Oklahoma City facility and consumed in prototype builds.
- $200,000 worth of materials were delivered to a wind tunnel facility in Kansas for testing.
- Oklahoma In-State Supplies: $600,000.
Contractor Sourcing Analysis
The contractor payments of $1,500,000 were distributed as follows:
- $1,000,000 to Oklahoma State University (OSU) for combustion testing (Incurred in OK).
- $500,000 to a private lab in Germany for metallurgical analysis (Incurred outside OK).
- Oklahoma In-State Contract Research (at 65%): $1,000,000 * 0.65 = $650,000.
Step 3: Calculation of the Oklahoma Rebate
The basis for the Oklahoma rebate is the sum of the in-state expenses:
OK QRE Basis = $3,000,000 + $600,000 + $650,000 = $4,250,000
The rebate amount is 5% of this basis:
Rebate Amount = $4,250,000 * 0.05 = $212,500
Step 4: Application and Compliance
Vanguard Propulsion submits its online application to the Department of Commerce on October 15, 2025. They include their federal Form 6765, a notarized attestation, and a project report detailing the Oklahoma-based activities. The Department of Commerce evaluates the application for completeness and eligibility. If the legislature appropriates funds to the Rebate Fund for the 2025 program year, and Vanguard is within the $20 million cap, they will receive a cash payment of $212,500.
Future Outlook and Compliance Risks
The shift to a rebate program brings both opportunities and risks for Oklahoma businesses. While the 5% cash return is highly attractive, the “subject to appropriation” and “first-come, first-served” elements create a volatile environment.
Documentation as a Competitive Advantage
In a first-come, first-served system, the speed and accuracy of the application are paramount. Businesses that maintain contemporaneous records—including technical reports that link specific expenditures to technological uncertainties—will be better positioned to submit their applications as soon as the window opens.
Potential Legislative Decoupling
One emerging risk is the potential for Oklahoma to “decouple” from federal changes to the R&D credit. For example, the 2017 Tax Cuts and Jobs Act (TCJA) requires research expenses under Section 174 to be amortized over five years rather than expensed immediately. Some states have enacted legislation to allow for immediate expensing despite the federal change. Because Oklahoma’s rebate currently relies on the federal definition of “qualified research expenses claimed on Form 6765,” any federal change in how those expenses are reported will have a direct ripple effect on the state rebate.
Comparison of State R&D Sourcing Rules
| State | R&D Sourcing Rule | Methodology |
|---|---|---|
| Oklahoma | “Incurred in this State” | Physical location of performance/consumption |
| Texas | “Conducted within this State” | Research must be performed in TX |
| Iowa | “Incurred in this State” | Consistent with alternative incremental credit |
| Florida | “Target Industry Business” | Qualified research under s. 41, IRC |
The Oklahoma Research and Development Rebate Program represents a sophisticated attempt to localize the benefits of the federal R&D tax credit. By mandating that expenses be “incurred in this state,” Oklahoma ensures that its taxpayers are only subsidizing innovation that builds local expertise, supports local wages, and utilizes local infrastructure. For businesses navigating this landscape, the key to success lies in meticulous geographic sourcing and a proactive approach to the Department of Commerce’s application process.

What is the R&D Tax Credit?
The Research & Experimentation Tax Credit (or R&D Tax Credit), is a general business tax credit under Internal Revenue Code section 41 for companies that incur research and development (R&D) costs in the United States. The credits are a tax incentive for performing qualified research in the United States, resulting in a credit to a tax return. For the first three years of R&D claims, 6% of the total qualified research expenses (QRE) form the gross credit. In the 4th year of claims and beyond, a base amount is calculated, and an adjusted expense line is multiplied times 14%. Click here to learn more.
