Research and Development in the Experimental or Laboratory Sense

The Analytical Framework of Experimental Research and Development

The standard of “research and development in the experimental or laboratory sense” is the foundational pillar upon which New York State builds its technological tax incentive landscape. Far from being a general descriptor of innovation, the phrase is a precise legal term of art, meticulously defined in the New York State Tax Law and further refined through decades of administrative guidance from the Department of Taxation and Finance (DTF). This definition serves a dual purpose: it distinguishes truly innovative endeavors from routine business activities and ensures that state subsidies—whether in the form of sales tax exemptions or refundable credits—are directed toward activities that generate new technical knowledge or solve complex engineering challenges.

At its core, the experimental sense focuses on the “ultimate goal” of the research activity. New York regulations stipulate that for an activity to qualify, it must strive toward one of several specific objectives. These include basic research in a scientific or technical field of endeavor, the advancement of technology in such a field, the development of new products, the improvement of existing products, or the discovery of new uses for existing products. The distinction here is critical; the law does not reward the mere application of existing knowledge to routine tasks, but rather the pursuit of solutions where the “capability, method, or design” of the final result is technically uncertain at the project’s inception.

The interpretation of this standard is deeply rooted in Federal Internal Revenue Code (IRC) Section 174, which historically defined research or experimental expenditures as costs incurred in the taxpayer’s trade or business representing R&D in the experimental or laboratory sense. New York adopts this federal heritage while layering its own specific administrative requirements, particularly regarding how tangible property is used “directly and predominantly” in the research process. This synergy between state and federal definitions creates a robust framework for taxpayers, but it also necessitates a granular understanding of how local state revenue office guidance applies the law to real-world business operations.

Statutory Definitions and the Five Pillars of Experimental R&D

New York’s regulatory definitions, particularly under 20 NYCRR 528.11, establish five specific categories of research that constitute the “experimental or laboratory sense.” These categories form the primary criteria used by auditors and tax professionals to evaluate the eligibility of an activity.

Basic Research and Technological Advancement

Basic research is defined as investigative work in a scientific or technical field of endeavor where the primary aim is to gain new knowledge without a specific immediate application in mind. While this is often the domain of academic laboratories, commercial entities frequently engage in basic research during the early stages of drug discovery or materials science. Advancing technology, meanwhile, involves taking existing scientific principles and pushing their boundaries to achieve higher performance or new capabilities that were previously thought to be technically unfeasible.

Product Development and Improvement

The most common application of the experimental standard is in the development of new products or the improvement of existing ones. An “improvement” in this context must go beyond aesthetic or market-driven changes; it must enhance the “functionality, performance, reliability, or quality” of the product through technical means. For instance, modifying a medical device to be more energy-efficient through a re-engineered circuit board would meet the threshold, whereas changing the color of the device’s casing for branding purposes would not.

Discovery of New Uses

The final pillar involves the development of new uses for existing products. This occurs when a company identifies that a chemical compound designed for agricultural use might have therapeutic properties in human oncology. The research required to prove this new application, including testing for efficacy and safety within the new context, constitutes R&D in the experimental sense because it involves resolving significant technical uncertainty.

Goal of R&D in the Experimental Sense	Practical Application Example
Basic Research	Investigating the molecular properties of a new polymer
Advancing Technology	Engineering a quantum processor with lower error rates
New Product Development	Creating a first-of-its-kind biodegradable battery
Improving Existing Products	Enhancing the data-processing speed of a satellite sensor
New Uses for Existing Products	Adapting an industrial lubricant for use in aerospace engines

Local State Revenue Office Guidance: TSB-Ms and Advisory Opinions

The New York State Department of Taxation and Finance (DTF) provides critical clarifications through Technical Memoranda (TSB-M) and Advisory Opinions (TSB-A). These documents serve as the practical handbook for applying the “experimental or laboratory sense” standard to specific business sectors.

The Standard of Direct and Predominant Use

One of the most vital areas of guidance concerns the sales tax exemption for tangible personal property under Tax Law Section 1115(a)(10). To qualify, property must be used “directly and predominantly” in R&D in the experimental or laboratory sense.

The DTF defines “direct use” as the actual performance of the research work. Broadly, this includes materials worked on, machinery, equipment, and supplies used to carry out the experiments, and CAD/CAM computer hardware and software systems. However, usage in activities collateral to the actual research process is not deemed “direct.” For example, a laboratory table used for experiments is exempt, but the office desks and chairs used by the research department’s administrative staff are taxable.

“Predominant use” requires that the property be used for qualifying R&D more than 50% of the time it is in service. This creates a binary outcome for sales tax purposes: if a high-speed camera is used 60% of the time for R&D trials and 40% for marketing photos, the entire purchase is exempt. If the ratio were reversed, the entire purchase would be taxable.

Advisory Opinion TSB-A-97(51)S: Scientific Services

This advisory opinion provides an exhaustive look at what constitutes experimental research in the context of scientific testing services. The petitioner, Scientific Services S/D, Inc., sought guidance on whether purchases of reagents, laboratory tools, and specialized cloths used for testing cleaning agents were exempt. The DTF concluded that if the service results in the development of a new product or the improvement of an existing one, the purchases are exempt. However, if the service is merely “product testing” for quality control—checking if a batch of soap meets the established standard—it is not R&D in the experimental sense and the purchases are taxable.

Advisory Opinion TSB-A-15(44)S: Software and Administration

The DTF has been clear that software does not qualify for the R&D exemption simply because it is used by a tech company. In TSB-A-15(44)S, the department ruled that software performing administrative tasks such as processing and shipping orders, controlling materials, and tracking labor does not constitute research in the experimental or laboratory sense. To qualify, software must be an integral part of the research process itself, such as simulation software used to model structural stresses or software developed to advance the principles of computer science.

The Exclusion of Qualitative and Social Research

Guidance consistently reinforces that the experimental sense is limited to the physical and biological sciences, engineering, and computer science. Research in connection with literary, historical, or similar projects is explicitly excluded. Furthermore, efficiency surveys, management studies, consumer surveys, advertising, and promotions do not meet the standard, even if they involve complex data analysis, because they do not aim to solve a technological uncertainty through the principles of hard science.

The Four-Part Test: Aligning New York and Federal Standards

For the purpose of income tax credits, such as the Excelsior Research and Development Tax Credit, New York aligns its definition of “qualified research” with the federal four-part test established under IRC Section 41(d).

1. The Section 174 Test (Experimental Sense): The activity must satisfy the definition of research and development in the experimental or laboratory sense. This means the costs must be related to activities intended to discover information that would eliminate uncertainty concerning the development or improvement of a business component.
2. Technological in Nature Test: The research must fundamentally rely on the principles of the physical or biological sciences, engineering, or computer science.
3. Business Component Test: The taxpayer must intend to use the information discovered to develop a new or improved business component, which can be a product, process, software, technique, or formula held for sale, lease, or license, or used in the taxpayer’s trade or business.
4. Process of Experimentation Test: Substantially all of the activities must constitute a process of experimentation. This involves a systematic trial-and-error approach where the taxpayer identifies the uncertainty, develops hypotheses, and evaluates alternatives through modeling, simulation, or systematic testing.

Component of the Four-Part Test	New York Compliance Requirement
Experimental Nature	Must aim to eliminate uncertainty regarding design or method
Technological Base	Must use “hard science” principles (Physics, Chemistry, etc.)
Commercial Intent	Resulting component must be used in the business or sold
Experimental Process	Must document the evaluation of multiple alternatives

New York’s Specialized R&D Credit Programs

New York offers several specific programs that leverage the “experimental or laboratory sense” standard, providing different levels of benefit depending on the industry and the size of the business.

The Excelsior Research and Development Tax Credit

Housed within the Excelsior Jobs Program, this credit is available to firms in targeted industries, including biotechnology, pharmaceuticals, high-tech, clean technology, and manufacturing. The credit is valued at 50% of the portion of the federal R&D credit that relates to expenditures in New York. However, the state imposes a cap: the credit cannot exceed 6% of the qualified research expenditures (QREs) conducted in New York, or 8% for “green projects” that support technologies aimed at reducing greenhouse gases.

Participation in this program requires certification from Empire State Development (ESD) and a commitment to meeting job creation or investment thresholds. The credit is fully refundable and can be claimed over a benefit period of up to 10 years.

The Life Sciences Research and Development Tax Credit

This program is specifically designed to foster the life sciences ecosystem. It offers a refundable credit to “new” life sciences businesses (defined by ESD) that incur QREs in the state. The credit amount is tiered by company size:

• 20% of research and development expenditures for companies with fewer than 10 employees.
• 15% for companies with 10 or more employees.

The credit is allowed for up to three consecutive years and is limited to $500,000 per year per entity. A key distinction from the Excelsior credit is that the Life Sciences credit is calculated directly on the total QREs rather than being tied to the federal credit percentage, providing a simpler and often more lucrative path for early-stage biotech firms.

The Qualified Emerging Technology Company (QETC) Credit

Small businesses with total annual product sales of $10 million or less may qualify as a QETC. To be eligible, a company must primarily engage in R&D in fields like advanced materials, electronics, or biotechnology, and its ratio of research funds to net sales must meet specific thresholds determined by the National Science Foundation. The QETC Facilities, Operations, and Training Credit provides a 18% credit on the cost of R&D property and a 9% credit on QREs, with a total annual cap of $250,000.

Detailed Application and Example: The Case of “Vertex AeroSpace LLC”

To understand how these concepts converge, consider “Vertex AeroSpace LLC,” a startup based in the Rochester, NY area. Vertex is developing a new type of lightweight composite turbine blade intended to increase the fuel efficiency of small jet engines.

Phase 1: Procurement and Sales Tax Exemptions

In its first year, Vertex purchases a specialized 3D printer for carbon-fiber composites ($150,000) and a high-performance computer cluster for thermal simulation software ($50,000).

Analysis of “Experimental Sense”:

• The 3D printer and the computer cluster are used directly to perform the research work—specifically, creating prototypes and running simulations to eliminate uncertainty regarding the turbine blade’s structural integrity.
• Vertex issues an Exempt Use Certificate (Form ST-121) to its vendors. This exempts the company from the 8% combined state and local sales tax, providing an immediate cash flow benefit of $16,000.
• Vertex also purchases general office supplies and furniture for its sales team. Because these items are not used “directly and predominantly” in the research process, Vertex must pay sales tax on these purchases.

Phase 2: Solving Technical Uncertainty

The engineers at Vertex face a challenge: the composite blades delaminate under high-temperature stress. This is a classic example of “technical uncertainty.” They do not know the correct “design” or “method” to prevent this. They begin a systematic process of experimentation, testing five different resin formulations and three different fiber orientations.

Analysis of QREs:

• The wages paid to the engineers for the time spent on these trials are QREs. Vertex uses a payroll allocation method to document this.
• The carbon fiber and resins used in the failed prototypes are also QREs, as they are supplies used in the research process.

Phase 3: Claiming the Life Sciences/Excelsior Credit

If Vertex is certified as a “Life Sciences Company” and has 5 employees, it can claim the Life Sciences R&D credit.

• Total NY QREs: $300,000 (Wages + Supplies).
• Credit Rate: 20% (for <10 employees).
• Credit Amount: $60,000.
• Outcome: As a pre-revenue startup, Vertex receives a $60,000 refund from New York State after filing Form IT-648.

Phase 4: Utilities and Record-Keeping

Vertex operates its lab in a facility where the 3D printer and simulation servers run 24/7. To claim the 100% sales tax exemption on electricity for these machines, Vertex must maintain “adequate records,” typically an engineering survey, showing exactly how much power is consumed by the R&D equipment versus general facility lighting.

Federal Conformity and the Impact of Section 174 Amortization

A significant shift in the R&D landscape occurred with the Tax Cuts and Jobs Act (TCJA), which amended IRC Section 174 to require businesses to capitalize and amortize R&D expenses over five years (domestic) or 15 years (foreign), rather than deducting them immediately.

For New York taxpayers, this created a potential “tax trap.” Because New York typically conforms to the federal definition of income, the loss of the immediate deduction could increase state taxable income. However, in 2025, federal updates (the “One Big Beautiful Bill Act”) have provided a path for small businesses to retroactively claim immediate deductions for 2022-2024 or accelerate remaining deductions.

New York’s TSB-A-24(13)I provides guidance on how this interacts with partnership law. The DTF ruled that partners in an LLC can make a “subtraction modification” on their New York returns for the portion of wages and salaries disallowed as a deduction under federal law due to the claiming of the R&D credit. This ensures that the benefit of the state credit is not diluted by an increase in taxable income at the state level.

Documentation and Audit Readiness

The “experimental or laboratory sense” standard is one of the most frequently audited areas of the tax law. Success in an audit depends entirely on the quality of contemporaneous documentation.

Contemporary Evidence Requirements

A business cannot simply “estimate” its R&D costs at the end of the year. The DTF and ESD require evidence that was created at the time the research was performed.

• Project Lists and Narratives: For every project, there must be a description of the technical uncertainty and the scientific principles applied.
• Lab Notebooks and Prototypes: Physical or digital records of experiments, including photos of prototypes or results of computer simulations, serve as powerful evidence of a “process of experimentation”.
• Payroll Allocation: Detailed time-tracking that breaks down employee hours by project is essential to support wage claims.
• General Ledger Detail: R&D supplies should be coded to specific accounts or projects to facilitate an audit trail.

Document Type	Role in Proving “Experimental Sense”
Lab Notebooks	Documents the “trial and error” process and technical dead-ends
Engineering Surveys	Establishes the “direct and exclusive” use of utilities
Patent Applications	Provides objective evidence of intent to create something “new”
ESD Certificates	Proves the state has already reviewed and approved the business mission

Statistical Trends in New York R&D Spending

New York’s commitment to the experimental sciences is reflected in the significant volume of tax expenditures dedicated to these programs. The state’s strategy is to compete with traditional tech hubs like California and Massachusetts by offering fully refundable credits—a feature that is rare in other states and particularly attractive to pre-revenue startups.

The 2024 and 2025 Tax Expenditure Reports highlight the growing scale of these incentives.

Credit Type / Sector	2021 Actual ($ Millions)	2025 Forecast ($ Millions)
Investment & R&D Credits (Article 9-A)	95.8	105.0
Personal Income Tax R&D Share	45.2	75.0
Total Cross-Article R&D Incentives	141.0	180.0

Data compiled from NY State Cross-Article Tax Credit Estimates.

Furthermore, New York’s Life Science Initiative, authorized with a $620 million budget, includes $200 million dedicated solely to R&D and job creation tax credits. The state currently ranks second in the nation for NIH funding, receiving approximately $3.6 billion, and third for the number of bioscience patents issued, demonstrating a strong correlation between these tax policies and actual scientific output.

Emerging Themes: Green R&D and Strategic Industries

The future of New York’s experimental R&D standard is increasingly tied to the state’s environmental goals. The “Green Project” incentive within the Excelsior program is a prime example. To qualify for the enhanced 8% credit rate, a project must aim to reduce greenhouse gases or create clean energy solutions through a process of experimentation.

This indicates a broadening of the “technological in nature” test to include specific policy outcomes. While the fundamental requirement for hard science remains, the state is actively steering the “experimental sense” toward solving the technical uncertainties of the climate crisis. This trend is likely to continue, with future legislation potentially offering even higher rates for “transformational” projects like semiconductor supply chains or “Green CHIPS” initiatives.

Final Thoughts: Navigating the Experimental Standard for Business Growth

The meaning of research and development in the experimental or laboratory sense is the critical junction where scientific innovation meets fiscal policy in New York State. For a business, understanding this standard is the difference between a routine tax filing and a million-dollar infusion of capital. By meticulously aligning research goals with the state’s five pillars—ranging from basic research to the improvement of existing products—and adhering to the “direct and predominant use” standard for property, firms can significantly reduce the cost of innovation.

The administrative burden of these programs is substantial, requiring contemporaneous records and proactive certification through Empire State Development. However, the reward—a fully refundable credit in a state that ranks at the top of national R&D spend—is a powerful catalyst for growth. As the state continues to refine its “Green” and “Life Science” incentives, the experimental sense will remain the primary vehicle for New York’s transition into a global leader of the 21st-century technology economy. For professional peers in the tax and engineering sectors, the “experimental sense” is not merely a definition to be satisfied, but a strategic asset to be leveraged for long-term competitiveness in the New York market.
