Research and Development Sales Tax Exemption

The Research and Development Sales Tax Exemption provides a full exemption from state and county sales and use taxes for machinery and equipment used primarily in research and development, while the Ohio Research and Development Investment Tax Credit offers a nonrefundable seven percent credit against the Commercial Activity Tax for qualified research expenses that exceed a taxpayer’s historical three-year average. These mechanisms collectively lower the fiscal barriers to innovation by reducing the up-front cost of capital assets and the ongoing operational costs of scientific inquiry and technological advancement within the state.

Technical Foundations and Statutory Framework of Ohio Innovation Incentives

The architecture of Ohio’s tax incentives for innovation is built upon a dual-track system that addresses both the acquisition of tangible property and the expenditure on intellectual labor. This system is codified within the Ohio Revised Code (ORC) under Chapter 5739 for Sales Tax and Chapter 5751 for the Commercial Activity Tax (CAT). The Research and Development Sales Tax Exemption is an expenditure-based relief mechanism that functions at the point of transaction, ensuring that companies do not pay the standard state and local sales tax on the highly specialized tools required for research. In contrast, the Ohio Research and Development Investment Tax Credit is an activity-based incentive that rewards firms for increasing their year-over-year investment in the research process itself, including wages paid to researchers and the supplies they consume.

The historical evolution of these provisions reflects a strategic shift in Ohio’s economic policy. Prior to the mid-2000s, many of these incentives were applied against the corporate franchise tax. However, with the introduction of the Commercial Activity Tax, which is based on gross receipts rather than net income, the state transitioned the R&D Investment Tax Credit to the CAT framework to maintain the state’s competitive posture for technology-oriented firms. This transition ensured that the incentive remained relevant in a modern tax environment where capital-intensive and high-revenue businesses might otherwise face significant tax burdens despite low profit margins during the research phase of their business cycles.

The legal basis for the sales tax exemption resides in ORC 5739.02(B)(43)(i), which specifically excludes qualified research and development equipment from the levy of sales tax. This exemption is predicated on the definition of research and development found in ORC 5739.01(GG), which encompasses designing, creating, or formulating new or enhanced products, equipment, or manufacturing processes, as well as conducting scientific or technological inquiry in the physical sciences. The state’s goal is to increase scientific knowledge and reveal the foundations for new or enhanced products, thereby fostering a cycle of continuous industrial improvement.

Incentive Type	Statutory Authority	Tax Offset	Primary Focus
R&D Sales Tax Exemption	ORC 5739.02(B)(43)(i)	Sales and Use Tax	Capital Equipment & Machinery
R&D Investment Tax Credit	ORC 5751.51	Commercial Activity Tax	Wages, Supplies, & Contracts
R&D Investment Loan	ORC 166.21	CAT (Loan Repayment)	Facility & Large Scale CapEx

The interplay between these two statutes creates a comprehensive ecosystem. While the sales tax exemption lowers the entry price for a new laboratory or testing facility, the CAT credit reduces the ongoing tax liability generated by the revenue resulting from those research efforts. This synergy is particularly vital for the manufacturing and software development sectors, where the cost of specialized equipment like electron microscopes, high-performance computing clusters, or precision prototyping machinery can be prohibitive if subject to standard taxation.

Detailed Analysis of the Research and Development Sales Tax Exemption

The Research and Development Sales Tax Exemption is one of the most powerful tools in the Ohio tax code for capital-intensive industries. It provides an immediate cash-flow benefit by exempting the entire state and county sales tax—which can range significantly depending on the jurisdiction—for purchases of qualified machinery and equipment used primarily for research and development.

Defining Qualified Research and Development Equipment

Under ORC 5739.01(HH), qualified research and development equipment is defined as capitalized tangible personal property, and leased personal property that would be capitalized if purchased, used by a person primarily to perform research and development. This definition contains two critical legal hurdles that taxpayers must clear: the Capitalization requirement and the Primary Use standard.

The capitalization requirement has historically been a point of contention between taxpayers and the Department of Taxation. Under Generally Accepted Accounting Principles (GAAP), specifically FASB Statement 2, most costs associated with R&D, including equipment that has no alternative future use, must be expensed immediately rather than capitalized. However, the Ohio Tax Commissioner has issued guidance clarifying that equipment used in R&D that has been expensed under FASB Statement 2 will still be considered capitalized for sales tax purposes if the property has a useful life substantially beyond the taxpayer’s annual accounting period. This ensures that the tax law does not punish firms for following rigorous financial accounting standards.

The Primary Use standard requires that the equipment be used more than fifty percent of the time for qualifying R&D activities. In many industrial settings, machinery may serve dual purposes—functioning as both a production tool and a testing platform. If the equipment’s primary function is the formulation of new products or the scientific inquiry into new processes, the entire purchase price is exempt from tax. If the R&D use is secondary to regular production, the exemption generally does not apply, and the item becomes taxable unless it qualifies under a different exemption, such as the manufacturing exemption.

Categorization of Research Activities: Direct vs. Pure

The exemption applies to two distinct types of research activity, both of which are central to the technological advancement of the state’s industrial base:

The first category is Direct Research, which refers to activities conducted to design, create, or formulate new or better products, equipment, or processes. This is inherently applied research, focusing on the development of tangible improvements to existing market offerings or the creation of entirely new business components. Examples include the engineering of a more efficient automotive engine, the design of a custom glass partition wall with specific acoustic properties, or the development of a more durable alloy for aerospace components.

The second category is Pure Research, which refers to scientific or technological inquiry and experimentation in the physical sciences. Unlike direct research, pure research may not have an immediate commercial application but is aimed at increasing the fundamental body of scientific knowledge. This might include laboratory work to understand the molecular behavior of polymers or the development of new algorithms in computer science that could eventually lead to breakthroughs in artificial intelligence. By including pure research, Ohio encourages the presence of high-level scientific talent and foundational discovery within its borders.

Exemption for Manufacturing-Related Research

There is a significant and often complex overlap between the R&D sales tax exemption and the Manufacturing Exemption found in ORC 5739.02(B)(42)(g) and Administrative Rule 5703-9-21. The manufacturing exemption applies to items used primarily in a manufacturing operation to produce tangible personal property for sale. A manufacturing operation is defined as a process in which materials are changed, converted, or transformed into a different state or form.

For a manufacturer, the R&D exemption provides a bridge between the conceptual phase and the production phase. While the manufacturing exemption covers the machinery on the assembly line, the R&D exemption covers the equipment in the engineering lab used to design the product that the assembly line will eventually build. Notably, testing equipment used to test in-process product is considered part of the continuous manufacturing operation and is exempt under the manufacturing rule, provided it is physically and functionally integrated into the production line. However, equipment used for testing that is not integrated, or that is used for testing new designs prior to the commencement of a manufacturing operation, must rely on the R&D exemption.

Exemption Type	Operational Phase	Integration Requirement
Manufacturing	Continuous Production	Physically & Functionally Integrated
Research & Development	Design & Formulation	Used primarily for inquiry/design
Packaging	End of Production	Used for retail-ready packaging

Mechanics of the Ohio Research and Development Investment Tax Credit (CAT)

The Ohio Research and Development Investment Tax Credit, authorized under ORC 5751.51, is a nonrefundable credit that serves as the primary operational incentive for innovation in the state. It is calculated based on qualified research expenses (QREs) as defined in Section 41 of the Internal Revenue Code, which ensures that the Ohio credit aligns closely with the federal R&D tax credit.

The Incremental Nature of the Credit

The Ohio R&D credit is designed as an incremental credit, meaning it rewards businesses for increasing their research footprint in the state. The credit equals seven percent of the amount by which the taxpayer’s current-year qualified research expenses in Ohio exceed their average annual research expenses over the three preceding taxable years. This base period calculation focuses solely on historical expenditures, making it a straightforward calculation for businesses with consistent growth.

If a taxpayer has not previously conducted research in Ohio, the base amount is zero, allowing the seven percent credit to apply to the entirety of their first-year expenditures. This provides a massive incentive for out-of-state companies to relocate or expand their R&D divisions to Ohio. Any credit that exceeds the taxpayer’s Commercial Activity Tax liability for the year may be carried forward for up to seven years.

Qualified Research Expenses and the Four-Part Test

To qualify for the CAT credit, research activities must meet the federal Four-Part Test established by the IRS. This ensures that the credit is directed toward true scientific and technological advancement rather than routine product maintenance or cosmetic changes.

The first part of the test is the Permissible Purpose, which requires that the research be intended to develop a new or improved business component’s function, performance, reliability, or quality. The second part, Elimination of Uncertainty, requires that the activity be intended to discover information that would eliminate uncertainty regarding the capability, method, or design of the product or process. The third part is the Process of Experimentation, which mandates that the taxpayer undergo a systematic process designed to evaluate one or more alternatives. Finally, the fourth part, Technological in Nature, requires that the process of experimentation fundamentally rely on the principles of physical or biological science, engineering, or computer science.

Qualified Research Expenses (QREs) that can be included in the calculation are:

• Wages: Salaries and wages paid to employees who perform, supervise, or directly support the research.
• Supplies: Any tangible personal property, other than land or improvements to real property, used in the research process, including materials for prototypes.
• Contract Research: Sixty-five percent of the amounts paid to third parties for research conducted in Ohio on the taxpayer’s behalf.
• Computer Leases: Costs associated with leasing computers or high-performance equipment used exclusively in qualified research.

Expense Category	Includable Amount	Specific Ohio Requirement
Internal Wages	100% of Qualifying Time	Must be performed in Ohio
Supplies	100% of Consumables	Must be used in Ohio research
Contract Research	65% of Payments	Activity must occur in Ohio
Computer Leases	100% of Rental Cost	Equipment must be for R&D use

Recent Legislative Changes: HB 33 and the CAT Exclusion Thresholds

The application of the R&D Investment Tax Credit has been significantly impacted by the passage of House Bill 33 (135th General Assembly). This legislation fundamentally altered the Commercial Activity Tax by dramatically increasing the exclusion amounts, thereby removing thousands of small and medium-sized businesses from the CAT rolls altogether.

Effective January 1, 2024, the exclusion amount for taxable gross receipts increased from $1 million to $3 million. In 2025, this threshold will increase again to $6 million. For businesses whose Ohio-sourced receipts fall below these levels, there is no CAT liability against which to apply the R&D tax credit. However, the R&D Sales Tax Exemption remains fully available to these businesses regardless of their total revenue, as it is a transaction-based tax rather than a gross receipts-based tax. Furthermore, any R&D credits earned by these businesses can still be carried forward for seven years, providing a banked tax benefit should the company’s receipts grow beyond the $6 million threshold in the future.

State Revenue Office Guidance and Administrative Procedures

The Ohio Department of Taxation (ODT) provides the operational framework for claiming these incentives through Information Releases, Administrative Rules, and Tax Commissioner Opinions. Understanding this guidance is essential for ensuring compliance and mitigating audit risk.

Claiming the Sales Tax Exemption: Certificates and Documentation

The process for obtaining the R&D sales tax exemption is decentralized and relies on the use of Exemption Certificates. Under ORC 5739.03(B), a vendor is required to collect sales tax on every transaction unless the consumer provides a properly completed exemption certificate.

The ODT has authorized several forms for this purpose, most notably the Blanket Exemption Certificate (Form STEC-B). This certificate allows a consumer to make a continuing claim of exemption on all purchases from a specific vendor. The purchaser must specify the reason for the exemption—in this case, Qualified Research and Development Equipment—and sign the form. Once a vendor receives a fully completed certificate in good faith, they are relieved of the liability for collecting and remitting the tax.

It is a common misconception that the State of Ohio issues an exemption number. In reality, no such number exists; the exemption is substantiated solely by the certificate and the underlying documentation of the equipment’s usage. For businesses under audit, ODT will look for records that prove the equipment was used primarily for R&D, such as project logs, engineering reports, and asset capitalization schedules.

Claiming the CAT R&D Credit: Filing and Record Retention

Unlike many other state credits, the Ohio R&D Investment Tax Credit does not require a prior application or certification from a state agency like the Department of Development. It is claimed directly on the taxpayer’s CAT return (typically Form CAT 210).

However, the Department of Taxation has issued strict guidance on record retention. Taxpayers must retain all records used to calculate the credit for at least four years after the return is filed. This includes not only the records for the current tax year but also the documentation for the three base years used to determine the incremental increase. The Tax Commissioner has the authority to audit a representative sample of the taxpayer’s research expenses to verify the validity of the credit claim.

Guidance on the “Agency” Relationship in Research Contracts

A significant area of revenue office guidance involves the definition of an agent for CAT purposes, as detailed in Information Release CAT 2006-03. In the context of contract research, if an entity acts as an agent for a principal, the amounts received for research may be excluded from the agent’s gross receipts, with only the commission or fee being taxable. This is critical for research firms and university partnerships that operate as intermediaries in large-scale R&D projects. To establish an agency relationship, there must be a consensual fiduciary relationship where the agent has the power to bind the principal and the principal has the right to control the agent’s actions. The burden of proof remains on the taxpayer to demonstrate this relationship through written contracts and factual evidence of control.

Comparative Analysis: The Synergy of Dual-Track Incentives

While the sales tax exemption and the CAT credit are distinct legal mechanisms, they operate as a unified fiscal strategy to support the entire lifecycle of a research project. The sales tax exemption targets the Infrastructural Phase (acquiring tools), while the CAT credit targets the Operational Phase (performing the work).

Side-by-Side Comparison of Requirements and Benefits

Feature	R&D Sales Tax Exemption	R&D Investment Tax Credit (CAT)
Tax Type	Sales and Use Tax	Commercial Activity Tax
Asset Focus	Tangible Machinery & Equipment	Wages, Supplies, Contract Costs
Benefit Rate	Full Exemption (State & County rate)	7% of Incremental Excess
Qualifying Test	Primary Use (>50% R&D)	IRC Section 41 (4-Part Test)
Timing of Benefit	Realized at Point of Sale	Realized on Quarterly/Annual Tax Return
Refundability	N/A (Up-front savings)	Nonrefundable
Carryforward	N/A	7 Years
Approval Process	Vendor Exemption Certificate	Direct Claim on Tax Return

The most significant strategic difference between these two incentives lies in their impact on cash flow. The sales tax exemption provides an immediate, dollar-for-dollar reduction in the cost of capital. If a company buys a $1 million testing chamber in a county with a 7.5% tax rate, it saves $75,000 the moment the transaction occurs. The CAT credit, however, is a retrospective benefit claimed months after the expenses are incurred. For a startup or a company in a loss position, the immediate savings of the sales tax exemption are often more critical for sustaining operations than a tax credit that may not be usable for several years.

Comprehensive Example: The Advanced Propulsion Systems Case Study

To illustrate the interplay of these laws, consider the case of Advanced Propulsion Systems (APS), an Ohio-based engineering firm specializing in hydrogen fuel cell development. In 2024, APS embarked on a major expansion of its research capabilities in Columbus, Ohio.

Phase 1: Capital Acquisition and Sales Tax Exemption

APS purchased $2,000,000 worth of specialized equipment, including high-pressure hydrogen testing tanks, a custom-built dynamometer, and advanced thermal imaging cameras.

• Analysis of Usage: The engineers at APS determined that the dynamometer would be used 100% of the time for testing new fuel cell prototypes (Direct Research). The thermal imaging cameras would be used 60% of the time for R&D and 40% of the time for regular quality control of existing products.
• The Primary Use Test: Both the dynamometer and the cameras meet the primary use standard because their R&D usage exceeds 50%.
• Execution: APS issued a Blanket Exemption Certificate to its equipment vendors, citing ORC 5739.02(B)(43)(i) as the basis for the claim.
• The Result: Columbus has a combined sales tax rate of 7.5%. By claiming the exemption, APS saved $150,000 in up-front costs, which it diverted into hiring two additional junior researchers.

Phase 2: Operational Research and the CAT Credit

During the 2024 tax year, APS incurred significant operational expenses related to the hydrogen project.

• Qualified Research Expenses (2024):
• Wages for R&D Personnel: $1,200,000
• Supplies (Hydrogen gas, consumable sensors): $300,000
• Contract Research with Ohio State University: $200,000 ($130,000 includable at 65%).
• Total 2024 QREs: $1,630,000.
• Establishing the Base Amount: APS has been conducting research in Ohio for several years. Its QREs for the three preceding years were:
• 2021: $1,100,000
• 2022: $1,200,000
• 2023: $1,300,000
• Average Base Amount: $1,200,000.
• Calculating the Credit:
• Excess QREs: $1,630,000 – $1,200,000 = $430,000.
• 7% Credit: $430,000 x 0.07 = $30,100.
• Applying the Credit: APS has $12,000,000 in Ohio taxable gross receipts. After the $3,000,000 exclusion for 2024, its taxable base is $9,000,000.
• CAT Liability (at 0.26%): $23,400.
• Final Tax Due: $0 (The $30,100 credit completely offsets the $23,400 liability).
• Carryforward: APS carries forward the remaining $6,700 for use in 2025.

Case Study Synthesis: The Cumulative Benefit

Through the strategic use of both incentives, APS realized a total tax benefit of $180,100 in a single year ($150,000 in sales tax savings and $30,100 in CAT credits). This represents nearly 10% of their total investment in the fuel cell project, significantly reducing the innovation tax that might otherwise stifle technological advancement in less incentive-friendly jurisdictions.

Deeper Second and Third-Order Insights

The structure of Ohio’s R&D incentives reveals an underlying philosophy focused on long-term industrial resilience rather than short-term corporate welfare.

The Evolution of the “Capitalization” Paradox

The conflict between FASB 2 and ORC 5739.01(HH) is a classic example of how tax law must adapt to evolving accounting standards. By allowing expensed R&D equipment to be treated as capitalized for tax purposes, the state has effectively decoupled tax relief from financial optics. This allows public companies to report conservative earnings (by expensing R&D immediately) while still receiving the cash-flow benefits of the tax exemption. This creates a hidden stimulus for the manufacturing sector, where the useful life of machinery often far outlasts the duration of a specific research project.

The Impact of “Substantial Nexus” and “Bright-Line Presence”

The 2024 and 2025 increases in the CAT exclusion thresholds ($3 million and $6 million, respectively) create a safe harbor for early-stage startups. However, the state’s bright-line presence rules remain aggressive. A company that exceeds $500,000 in Ohio sales or $50,000 in Ohio property or payroll is considered to have a substantial nexus with the state.

This creates a strategic tension: smaller firms may be exempt from the CAT, but they are still subject to the sales tax and its accompanying compliance requirements. For these smaller firms, the R&D Sales Tax Exemption is not just an incentive; it is the only available state-level innovation relief, as they cannot benefit from a credit against a tax they do not owe. This places a premium on the correct use of exemption certificates and the documentation of equipment primary use for the smallest and most innovative companies in the state.

Integration with JobsOhio and Economic Development Loans

The R&D Investment Tax Credit does not exist in a vacuum; it is often part of a larger incentive stack that includes JobsOhio programs. The Research and Development Investment Loan Fund is a prominent example, providing low-interest financing for projects that create high-wage R&D jobs.

A firm that secures an R&D Investment Loan can receive a separate CAT credit equal to the amount of principal and interest repaid on that loan, up to $150,000 per year. This Loan Repayment Credit is additive to the 7% incremental R&D tax credit. For a company undertaking a massive facility expansion, the combination of low-interest financing, a loan repayment credit, an incremental investment credit, and a sales tax exemption on all machinery creates one of the most favorable fiscal environments for research in the United States.

Strategic Recommendations for Compliance and Optimization

Given the complexity of the Ohio tax code and the aggressiveness of Department of Taxation audits, professional peers should consider the following strategic imperatives when managing R&D incentives.

The Necessity of Contemporaneous Documentation

The single most common reason for the denial of R&D tax claims is a lack of contemporaneous documentation. Auditors are often skeptical of look-back studies that rely on estimates or memory. To withstand scrutiny, companies must maintain real-time logs that tie specific employee hours and supply purchases to the Four-Part Test projects. For the sales tax exemption, maintenance logs or usage certificates for laboratory equipment can provide the necessary evidence to prove the primary use standard.

Leveraging the “Blanket” Exemption Strategy

To minimize administrative burden, companies should prioritize the use of Blanket Exemption Certificates (STEC-B) with their regular vendors. However, these certificates should be reviewed annually. If a company’s research activities shift or if equipment is repurposed for general production, the blanket certificate may no longer be valid in good faith, exposing the company to significant back-tax liability, penalties, and interest.

Coordination Between Tax and Engineering Departments

The gap between tax law and engineering reality is where most innovation incentives are lost. Engineers often view research through a different lens than the tax code. A process that an engineer considers standard troubleshooting might actually meet the Elimination of Uncertainty and Process of Experimentation tests for the R&D tax credit. Regular briefings between the tax department and the engineering teams are essential to identify all qualifying activities and equipment.

Final Thoughts

The landscape of Ohio’s R&D incentives is defined by its permanence and its stability. Unlike the federal R&D credit, which has occasionally been subject to expiration and legislative renewal, the Ohio R&D Investment Tax Credit is a permanent feature of the state’s Commercial Activity Tax. This allows companies to make twenty and thirty-year capital investment decisions with a high degree of certainty regarding their long-term tax liability.

As the global economy shifts toward advanced manufacturing, biotechnology, and clean energy, the Research and Development Sales Tax Exemption and the CAT credit will remain the twin engines of Ohio’s competitive strategy. By continuing to align state tax law with federal definitions while providing unique transaction-level relief through the sales tax exemption, Ohio has created a model that favors the makers and the thinkers—the firms that physically build the future within the state’s borders.

The recent expansion of CAT exclusions in HB 33 signals a future where Ohio remains a haven for small-scale innovation, while its integrated loan and credit programs ensure that as these companies grow, the state remains their partner in the high-stakes world of global research and development. For the professional tax practitioner, success in this environment requires a deep mastery of the administrative code, a rigorous approach to documentation, and a strategic eye toward the synergy of property-based and activity-based tax relief.
