Ohio-Incurred Qualified Research Expenses

Ohio-Incurred Qualified Research Expenses are costs for research activities performed within the state that meet Internal Revenue Code Section 41 standards, including wages, supplies, and contract research. These expenses form the basis for a 7% nonrefundable credit against the Ohio Commercial Activity Tax for costs exceeding a taxpayer’s three-year historical average.

The landscape of business taxation in Ohio underwent a radical transformation in the mid-2000s, shifting from a traditional corporate income tax model to a gross receipts tax known as the Commercial Activity Tax (CAT). Within this framework, the state preserved and refined incentives for innovation, specifically through the Research and Development Investment Tax Credit. This credit is not merely a deduction but a powerful tool designed to reduce a taxpayer’s bottom-line tax liability based on the “incremental” growth of their research investments within the geographic boundaries of the state. To understand the meaning of Ohio-Incurred Qualified Research Expenses (QREs), one must look at the intersection of federal tax definitions, state jurisdictional requirements, and the specific administrative procedures mandated by the Ohio Department of Taxation. The credit serves as a vital economic engine, encouraging companies in sectors ranging from advanced manufacturing to software development to anchor their high-value technical operations in Ohio.

Legal Foundation and Statutory Framework of the Ohio R&D Credit

The primary statutory authority for the Ohio R&D tax credit is found in Section 5751.51 of the Ohio Revised Code (ORC). This section establishes the credit as a nonrefundable incentive available to taxpayers subject to the Commercial Activity Tax. Historically, this incentive was part of the Ohio Corporation Franchise Tax under Section 5733.351, but as that tax was phased out for most entities between 2005 and 2010, the credit was transitioned to the CAT to ensure continuity in the state’s support for industrial and scientific advancement.

The Adoption of Internal Revenue Code Section 41

The Ohio legislature made a deliberate policy choice to align the state’s definition of research expenses with the federal standard. ORC 5751.51(A) explicitly states that “qualified research expenses” has the same meaning as defined in Section 41 of the Internal Revenue Code (IRC). This alignment provides a level of predictability for multi-state corporations, as the core activities that qualify for the federal Credit for Increasing Research Activities typically also qualify in Ohio.

Under IRC Section 41, QREs are generally comprised of three main categories: in-house wages, supplies, and a portion of contract research expenses. For an activity to generate these expenses, it must satisfy the rigorous “Four-Part Test” established by federal law and adopted by Ohio revenue officials:

1. The Section 174 Test: The activity must be intended to discover information that would eliminate uncertainty concerning the development or improvement of a business component, such as a product, process, or software.
2. The Technological Information Test: The research must rely on the principles of physical or biological sciences, engineering, or computer science.
3. The Business Component Test: The research must relate to a new or improved function, performance, reliability, or quality of a product or process held for sale or used in the trade or business.
4. The Process of Experimentation Test: Substantially all of the activities must constitute a process of experimentation, involving the evaluation of alternatives through modeling, simulation, or systematic trial and error.

The Jurisdictional Distinction: “Incurred in This State”

While Ohio adopts the federal definition of what constitutes a research expense, it adds a critical geographical limitation. ORC 5751.51(B)(1) requires that the expenses be “incurred in this state”. This is the most significant point of departure from the federal credit, which allows for research performed anywhere in the United States or its territories. For an expense to be an “Ohio-Incurred” QRE, the underlying activity must physically take place within Ohio’s borders.

This requirement places a burden on the taxpayer to bifurcate their research costs. For example, if a company has a research facility in Columbus, Ohio, and another in Ann Arbor, Michigan, only the wages paid to the Ohio-based researchers and the supplies consumed in the Columbus lab can be included in the Ohio credit calculation. Administrative guidance from the Ohio Department of Taxation further clarifies that “incurred in this state” applies to the location where the service is performed or the property is used, not necessarily where the taxpayer is headquartered or where the payroll is processed.

Administrative Guidance from the Ohio Department of Taxation

The Ohio Department of Taxation provides the operational “road map” for claiming the credit through Administrative Code rules and Information Releases. These documents represent the official stance of the local revenue office on how the law applies to daily business operations.

Ohio Administrative Code Rule 5703-29-22

The primary administrative rule governing CAT credits is OAC 5703-29-22. This rule provides essential definitions and procedural requirements for the R&D credit. Key provisions include:

• Computation Period: Regardless of whether a taxpayer files CAT returns quarterly or annually, the R&D credit must be computed based on expenses incurred during the calendar year, not the taxpayer’s fiscal year.
• Filing Deadlines: Annual filers must first claim the credit on the annual return due in May. Quarterly filers must claim the credit on the fourth-quarter return due in February of the year following the calendar year for which the credit is claimed.
• Non-Refundability and Carryforward: The rule confirms that any portion of the credit that remains unused after being applied against the tax liability may be carried forward for no more than seven years.

Information Release CAT 2007-03

Issued to explain the mechanics of CAT credits, Information Release CAT 2007-03 (and its subsequent revisions) serves as the definitive guide for taxpayers. This guidance emphasizes the necessity of the “CAT CS” schedule, which is the form used to report credit information. The Department of Taxation uses this schedule to track the member-by-member calculations required for consolidated and combined taxpayer groups.

The information release also clarifies the “Order of Credits.” Under ORC 5751.98, the R&D credit must be claimed in a specific sequence relative to other credits like the Job Creation Tax Credit or the Jobs Retention Tax Credit. This ensures that nonrefundable credits with shorter carryforward periods are utilized before those with longer windows, though the R&D credit’s seven-year window is standard for most Ohio business incentives.

Analysis of Qualifying Expense Categories

To properly compute “Ohio-Incurred” QREs, a taxpayer must categorize their costs into the three buckets defined by IRC 41 and verified by Ohio’s administrative standards.

Qualifying Wages and Personnel Costs

Wages represent the largest portion of most R&D credit claims. For these to qualify in Ohio, the employee must perform “qualified services” within the state. Qualified services include:

• Direct Research: The actual conduct of the research, such as laboratory experimentation or software coding.
• Direct Supervision: The immediate supervision of those conducting research. This excludes high-level management that only receives periodic reports on research progress.
• Direct Support: Tasks that support the research, such as a lab technician cleaning equipment or a machinist building a prototype.

The Department of Taxation strictly audits these costs. Taxpayers are expected to maintain payroll registers, W-2 forms, and, most importantly, time-tracking data that can substantiate the percentage of an employee’s time dedicated to Ohio-based research.

Qualifying Supply Expenses

Supplies include tangible property used in the research process that is not subject to depreciation. In the context of Ohio-Incurred QREs, these supplies must be “consumed” in Ohio during the research process. Examples include:

• Chemicals and reagents for laboratory testing.
• Materials used to fabricate prototypes.
• Computer rental or leasing costs for research purposes, though these are less common in the era of cloud computing.

It is important to note that the costs of land or improvements to land do not qualify, nor do general administrative supplies that are not directly used in the research activity.

Contract Research Expenses

When a taxpayer hires a third party to perform research, they may generally include 65% of the amount paid as a QRE. For Ohio purposes, the research performed by the contractor must be conducted within the state. This creates a “look-through” requirement where the taxpayer must verify that their vendor is actually performing the work at an Ohio location. Furthermore, the taxpayer must maintain “substantial rights” to the research and bear the “financial risk” of the project—meaning the contractor cannot guarantee a successful result.

The Mechanical Calculation of the Credit

The Ohio R&D credit is an “incremental” credit, which is intended to reward companies for increasing their investment in the state, rather than simply maintaining their current levels. The credit rate is 7% of the excess Ohio QREs over the “base amount”.

Step-by-Step Computational Process

The local revenue office guidance dictates a four-step calculation process:

1. Identify Current Year Ohio QREs: Sum all qualifying wages, supplies, and 65% of contract research incurred in Ohio during the calendar year.
2. Calculate the Base Amount: Determine the average of the Ohio-incurred QREs for the three preceding calendar years. If the company has no prior history in Ohio, the base is zero.
3. Determine the Excess: Subtract the base amount from the current year Ohio QREs.
4. Apply the 7% Rate: Multiply the excess by 0.07 to arrive at the total credit amount.

Multi-Year Average Example

To illustrate the calculation, consider a technology firm, “Dayton Aero Systems,” with the following spending profile:

Year	Ohio-Incurred QREs	Status
2021	$2,100,000	Prior Year -3
2022	$2,400,000	Prior Year -2
2023	$2,700,000	Prior Year -1
2024	$3,500,000	Current Claim Year

Calculation:

1. Base Amount: ($2.1M + $2.4M + $2.7M) / 3 = $2,400,000.
2. Excess: $3,500,000 (Current) – $2,400,000 (Base) = $1,100,000.
3. Credit: $1,100,000 * 0.07 = $77,000.

The firm would report a $77,000 nonrefundable credit on its fourth-quarter 2024 CAT return.

Group Filing Dynamics: Consolidated and Combined Taxpayers

One of the most complex areas of Ohio tax law involves how credits are handled for groups of companies. The CAT allows (and sometimes requires) related entities to file as a single taxpayer. However, the R&D credit calculation remains entity-specific.

Member-by-Member Requirements

Under ORC 5751.51(C), each person in a consolidated elected or combined taxpayer group must “separately calculate” the credit using their own incurred qualified research expenses. This means that even if a parent company and three subsidiaries file one CAT return, they must submit a schedule showing four separate R&D credit calculations.

Entity	2024 OH QRE	3-Year Avg	Excess	7% Credit
Parent Co	$500,000	$400,000	$100,000	$7,000
Sub A	$1,200,000	$1,300,000	($100,000)	$0
Sub B	$800,000	$200,000	$600,000	$42,000
Total	$2,500,000	N/A	N/A	$49,000

This member-by-member rule prevents a group from offsetting a decline in research at one subsidiary with an increase at another to manipulate the “incremental” nature of the credit.

Eligibility and Group Membership

Guidance from the Department of Taxation emphasizes that a group can only claim a credit for a member if that member was part of the group on December 31st of the year the expenses were incurred. Furthermore, unused credit carryforwards can only be claimed if the entity that generated them remains in the group at the end of the tax period for which the carryforward is used. If a subsidiary is sold, its unused R&D credits may be lost to the group unless specific statutory transfers are authorized.

Substantiation, Documentation, and Audit Defense

Because the R&D credit directly reduces tax revenue, the Ohio Department of Taxation subjects claims to high levels of scrutiny. ORC 5751.51(E) grants the Tax Commissioner explicit authority to audit a sample of a taxpayer’s expenses to ascertain the validity of the credit.

The Burden of Proof

In Ohio, tax reduction statutes are “strictly construed” against the taxpayer. This means that if there is ambiguity in the records, the state will likely deny the credit. Taxpayers must demonstrate a “clear entitlement” to the incentive. The Department of Taxation typically looks for a “nexus of documentation” that links:

• Project Technical Goals: Documentation of the technical uncertainty and the experimental process used to resolve it.
• Employee Activities: Contemporaneous logs or project notes showing what the researchers were doing in Ohio.
• Expense Verification: Invoices for supplies and contracts for outside research firms that specify where the work was performed.

Record Retention Standards

Taxpayers must retain all records used to calculate the credit for the current year and the three preceding base years. The retention period is four years after the return was filed or the due date, whichever is later. For a company with a high volume of R&D, this often necessitates a digital document management system specifically tailored to tax audit requirements.

Interplay with Other Ohio Incentives

The CAT R&D credit does not exist in a vacuum. It is part of a broader suite of state incentives designed to support the “innovation lifecycle,” from basic research to capital investment and job creation.

Research and Development Sales Tax Exemption

A frequent companion to the CAT credit is the R&D Sales Tax Exemption. This exemption applies to the purchase of machinery and equipment used primarily for research and development.

• Mechanism: The exemption applies at the point of sale, meaning the business does not pay the roughly 5.75% to 8% state and county sales tax on qualifying equipment.
• Definitions: It covers both “direct” research (product design/formulation) and “pure” research (scientific experimentation in physical sciences).
• Guidance: To claim this, the purchaser must provide the vendor with a “Sales and Use Tax Blanket Exemption Certificate”.

While the CAT credit focuses on recurring operational costs like wages, the Sales Tax Exemption focuses on capital equipment, providing a “double benefit” for companies building out new lab facilities in Ohio.

JobsOhio R&D Investment Loan and Repayment Credit

The state, through the private economic development corporation JobsOhio, offers an R&D Investment Loan program. This provides low-interest financing for large-scale R&D projects. Under ORC 5751.52, a separate nonrefundable credit is available for the payments made on these loans. This “Loan Payment Credit” is often capped (frequently at $150,000 per year) but can be stacked with the 7% QRE credit to further lower the cost of doing business in Ohio.

Current Fiscal Context and CAT Threshold Changes

The value and application of the R&D credit are currently being impacted by significant changes to the CAT enacted in the 2024-2025 biennial budget (House Bill 33). These changes have substantially increased the “exclusion amount”—the level of gross receipts a company can have before they owe any tax.

The Shifting CAT Landscape

Tax Period	Annual Exclusion Amount	Impact on R&D Credit
Prior to 2024	$1,000,000	Most R&D firms paid some CAT and could use the credit.
2024	$3,000,000	Smaller firms with <$3M in receipts no longer pay CAT; credit becomes less relevant for them.
2025+	$6,000,000	Only firms with >$6M in Ohio receipts will be subject to CAT and need the R&D credit.

For larger taxpayers who remain subject to the CAT, the tax rate remains 0.26% on receipts above the exclusion amount. Because the CAT is a tax on gross receipts rather than net profit, the R&D credit is particularly valuable for high-revenue, low-margin businesses like wholesale distributors or high-volume manufacturers who invest heavily in process improvements.

Fiscal Impact of the Credit

While specific annual expenditure data for the R&D credit is often embedded within broader “Business Tax Credit” reports, the state estimates that business tax incentives contribute significantly to the General Revenue Fund’s performance. In fiscal year 2024, Ohio’s General Revenue Fund saw a decrease in tax revenue of 3.4%, partly due to the aforementioned CAT exclusion increases and various tax expenditures. However, the R&D credit is viewed by policy makers as a “pro-growth” expenditure that helps offset the high cost of maintaining a technical workforce.

Case Study: Ohio Automotive Parts Manufacturer

To synthesize how “Ohio-Incurred” QREs and the credit apply in a real-world business scenario, consider “Buckeye Auto Tech,” a company developing new lightweight alloy components for electric vehicles.

Scenario Details

• Location: Operations in Akron, Ohio, and a test track in Indiana.
• Ohio Workforce: 50 engineers in Akron.
• Expenses:
  • Ohio Wages for Engineers: $5,000,000.
  • Indiana Wages for Track Testing: $500,000.
  • Ohio Lab Supplies: $200,000.
  • Ohio-based Contract Research (65%): $130,000.
  • 3-Year Average Ohio QREs: $4,000,000.
  • 2024 Ohio Taxable Gross Receipts: $20,000,000.

Calculation of Ohio-Incurred QREs

The company must first exclude the Indiana wages, as they were not “incurred in this state”.

1. Total Ohio QREs: $5,000,000 (Wages) + $200,000 (Supplies) + $130,000 (Contract) = $5,330,000.
2. Excess QREs: $5,330,000 – $4,000,000 (Base) = $1,330,000.
3. Credit Amount: $1,330,000 * 0.07 = $93,100.

Application to Tax Liability

1. CAT Liability Calculation (2024): ($20M Receipts – $3M Exclusion) * 0.0026 = $44,200.
2. Credit Offset: The company applies $44,200 of its $93,100 credit to reduce its 2024 tax to $0.
3. Carryforward: The remaining $48,900 is carried forward to offset CAT liability in 2025 and beyond, for up to seven years.

This example demonstrates how the credit can completely eliminate the CAT liability for a research-intensive firm, even if that firm has high gross receipts.

Final Thoughts: Strategic Value of the Ohio R&D Credit

The Ohio Research and Development Investment Tax Credit, fueled by “Ohio-Incurred Qualified Research Expenses,” represents one of the most stable and predictable incentives in the state’s tax code. By coupling the federal IRC 41 definition with a 7% incremental rate against the Commercial Activity Tax, Ohio has created a system that rewards both innovation and geographic loyalty.

For the business professional, the key to maximizing this credit lies in rigorous adherence to administrative guidance. The Department of Taxation’s requirements for member-by-member calculation in group filings, strict contemporaneous documentation, and the “in-state” performance of research activities mean that the credit is not “found money” but a benefit that must be meticulously earned and defended. As the state continues to refine its business tax thresholds through legislation like HB 33, the R&D credit will remain a cornerstone for larger enterprises and high-growth startups alike, ensuring that Ohio remains a premier destination for scientific discovery and industrial advancement. Properly utilized, this credit doesn’t just lower a tax bill; it provides the capital necessary for the next generation of breakthroughs to be discovered, developed, and deployed within the State of Ohio.
