Is Research and Development Subject to Sales Tax in Arkansas: What It Means for B2B Teams (2026)
By Kushal Magar · May 3, 2026 · 11 min read
Key Takeaway
R&D services are generally not taxable in Arkansas. Tangible property bought for R&D (equipment, chemicals, supplies) is taxable at 6.5% unless covered by the manufacturing exemption. SaaS and custom software used in research are exempt. The Arkansas R&D income tax credit is a separate benefit — it offsets income tax, not sales tax.
If your B2B team sells to Arkansas companies running research and development programs — or if you operate R&D labs yourself in the state — this question has real dollar implications.
Arkansas's sales tax rules on R&D are not complicated once you know the framework. But the framework is not intuitive, and the wrong assumption costs money.
TL;DR
- R&D services are generally exempt. Arkansas only taxes services explicitly listed in statute — R&D consulting and laboratory services are not on that list.
- Tangible property used in R&D is taxable by default. Equipment, supplies, chemicals, and prototypes are subject to 6.5% state sales tax unless an exemption applies.
- Manufacturing exemption may cover some R&D equipment — but only if the equipment is used directly in production of a product for commercial sale, not for pure research.
- SaaS and custom software are exempt. Cloud tools and hosted platforms used in research are not subject to Arkansas sales tax.
- The R&D income tax credit is separate. It reduces income tax liability by 20%–33% of qualifying expenditures — it does not exempt R&D purchases from sales tax.
- Use tax applies to out-of-state purchases. Equipment bought from out-of-state vendors without sales tax triggers Arkansas use tax at 6.5%.
Overview
This guide is for two audiences. First, B2B companies in Arkansas (or selling into Arkansas) that conduct research and development and need to understand their sales tax obligations on R&D-related purchases. Second, B2B sales and GTM teams selling into the Arkansas R&D market who want to understand how tax compliance shapes their buyers' purchasing decisions.
We cover Arkansas's general sales tax framework, how it applies to R&D services versus R&D purchases, the interaction with the manufacturing exemption, SaaS and software rules, and the Arkansas R&D income tax credit program. We also explain where SyncGTM fits for teams selling into R&D-intensive accounts.
Arkansas Sales Tax: The Basics
Arkansas imposes a 6.5% state sales tax on the gross receipts from sales of tangible personal property and certain specified services. Local jurisdictions add their own rates, which range from 0% to 6.125%, making the combined rate as high as 12.625% in some areas.
The key distinction in Arkansas is the treatment of services. Unlike states that tax most services by default, Arkansas takes the opposite approach: most services are exempt unless the legislature has specifically listed them as taxable.
According to the Arkansas Department of Finance and Administration, taxable services include utilities, repair and maintenance of physical property, landscaping, pool cleaning, telephone answering services, health club memberships, and similar enumerated categories. Research and development services are not on this list.
For tangible personal property, the rule reverses: everything is taxable unless a specific exemption applies. This asymmetry is the foundation of Arkansas's R&D sales tax treatment.
The Use Tax Mirror
Arkansas also levies a compensating use tax at 6.5%. Use tax applies when you purchase tangible personal property from an out-of-state vendor who does not collect Arkansas sales tax. It is self-reported and due on the same schedule as sales tax returns.
For R&D teams that buy specialized equipment or supplies from vendors outside Arkansas — a common pattern — use tax obligations are easy to miss. The purchase looks like a non-Arkansas transaction, but the state expects payment when the property is brought into or used in Arkansas.
Are R&D Services Taxable in Arkansas?
Research and development services — including contract research, laboratory analysis, engineering studies, scientific consulting, and prototype design — are not subject to Arkansas sales tax.
This is because Arkansas's sales tax on services is narrowly defined. Only services explicitly enumerated in Arkansas Code § 26-52-301 and related statutes are taxable. R&D services do not appear in that enumeration. Arkansas legal commentary and state-administered guidance confirm that professional and technical services, including research-related work, fall outside the taxable category.
What This Means Practically
If your company contracts with an Arkansas-based R&D firm for laboratory testing or applied research, that contract payment is not subject to sales tax. The service provider does not collect sales tax from you, and you do not owe use tax on the payment.
If you are the R&D service provider — a contract research organization, engineering firm, or biotech consultancy — you do not charge Arkansas sales tax on your service fees. This holds whether your client is in-state or out of state.
The boundary blurs when services include tangible deliverables. If your research contract delivers a physical prototype, report in binder form, or samples with the service, the tangible components may be separately taxable. The service portion remains exempt; the physical goods are potentially not.
R&D Equipment and Supply Purchases
This is where most R&D teams run into unexpected tax bills. Tangible personal property purchased for research and development is taxable in Arkansas by default.
That includes:
- Laboratory instruments and measurement equipment
- Chemicals, reagents, and consumables used in experiments
- Prototype materials and components
- Computers and servers purchased for research computing (when not in a qualifying manufacturing environment)
- Office equipment, safety gear, and lab furniture
Arkansas does not have a dedicated sales tax exemption for R&D equipment purchases the way some states do. For example, Arizona offers a specific R&D sales tax exemption for qualifying equipment. Arkansas does not have an equivalent provision as of 2026.
Chemicals and Reagents — A Gray Area
Arkansas manufacturing regulations exempt "catalysts, chemicals, reagents and solutions" consumed directly in the manufacturing process. This exemption covers materials that become part of the product or are consumed while producing it.
For R&D teams, the question is whether research-use chemicals qualify. The answer depends on how the research connects to production. If the chemicals are used in pre-commercial research with no direct link to a current manufacturing process, the manufacturing exemption likely does not apply. If the chemical testing is integral to quality control in an active production line, it may qualify.
This distinction requires documentation and often benefits from a formal ruling request to the Arkansas DFA.
| R&D Purchase Type | Default Tax Treatment | Exemption Possible? |
|---|---|---|
| Lab instruments and equipment | Taxable at 6.5% | Only if used directly in manufacturing |
| Chemicals and reagents (R&D use) | Taxable at 6.5% | Gray area — manufacturing link required |
| Prototype components and materials | Taxable at 6.5% | Generally no |
| Computers for research (non-manufacturing) | Taxable at 6.5% | No |
| Quality testing equipment (in active manufacturing) | May qualify for exemption | Yes — if testing finished goods quality |
| SaaS tools and cloud software | Not taxable | N/A — already exempt |
Software and SaaS Used in R&D
Arkansas treats software favorably. The rules are clear and favorable for most modern R&D operations.
SaaS is not taxable in Arkansas. Cloud-based software accessed remotely — research platforms, simulation tools, data analytics suites, lab management systems — are exempt from sales tax. Arkansas considers SaaS access to hosted software rather than a transfer of tangible property.
Electronically delivered software is also exempt, including prewritten software downloaded digitally and custom software created for a single user. The tax attaches only when software is delivered on physical media (a CD, USB drive, or similar tangible storage medium).
For B2B teams that run extensive digital R&D infrastructure, this means the tooling costs — cloud compute, hosted analytics, API services, CRM software — are not subject to Arkansas sales or use tax.
Digital Products Are Different
Arkansas does tax specified digital products: e-books, streaming audio, streaming video, and similar consumer digital goods. This category rarely intersects with R&D operations, but it is worth noting for completeness. Downloadable databases or digital data sets used in research could potentially fall into this category depending on how they are classified. When in doubt, request a letter ruling from the Arkansas DFA.
The Arkansas R&D Income Tax Credit
Arkansas offers substantial R&D incentives through its income tax credit programs — separate from sales tax entirely, but worth understanding as part of the complete R&D tax picture.
The Arkansas Economic Development Commission's R&D credit program offers four tiers:
| Program Tier | Credit Rate | Key Details |
|---|---|---|
| In-House R&D | 20% of spending above baseline | 5-year term; 9-year carryforward; offsets 100% of income tax |
| Strategic Value Research | 33% of qualified expenditures | Capped at $50,000/year per taxpayer |
| University-Based Research | 33% of qualified expenditures | Must contract with an Arkansas college or university |
| Targeted Business R&D | 33% of qualified expenditures | Requires AEDC designation; priority sectors only; transferable credits |
Qualifying expenditures under these programs include wages paid to employees performing qualified research and contracted research payments to Arkansas universities and research organizations. The research must be technological in nature, aimed at practical application, and involve systematic experimentation.
Critical Distinction: Income Tax vs. Sales Tax
These credits offset Arkansas income tax liability — not sales tax on R&D purchases. A company that spends $500,000 on qualified R&D wages may receive a $100,000 income tax credit under the in-house program. That same company still owes sales tax on the lab equipment it purchased to conduct that research.
The two tax systems operate independently. Both require separate compliance processes. Confusing them leads to either underestimating income tax savings or incorrectly exempting taxable purchases.
Manufacturing Exemption Overlap
Arkansas's manufacturing exemption is the closest thing to an R&D purchase exemption in the state — but it is not designed for R&D and has strict limits.
Under Arkansas law and the implementing regulation (Ark. Code R. 005-GR-55), machinery and equipment used directly in manufacturing are exempt from sales tax. "Directly in manufacturing" means the equipment performs an essential function in producing a product from raw materials through its finished commercial state.
What Qualifies
Equipment installed in a manufacturing plant that performs production functions qualifies. Quality testing equipment that measures the quality of a manufactured article as it exits production qualifies. Computers that directly control manufacturing process parameters qualify.
What Does Not Qualify
Equipment used exclusively for R&D that is not integrated into the production line does not qualify. Testing equipment used to evaluate raw materials before manufacturing begins is explicitly excluded. Office machines, hand tools, and administrative equipment are also excluded. Laboratory instruments used for pure research — with no direct tie to a live production line — fall outside the exemption.
The manufacturing exemption has been expanded significantly over time. As of July 1, 2022, repair and replacement parts for qualifying manufacturing equipment are fully exempt following a phased reduction that began in 2014.
The Documentation Requirement
To claim the manufacturing exemption on equipment that sits at the boundary of research and production, documentation is critical. You need to demonstrate that the equipment is directly integrated into production functions, not merely adjacent to them. Arkansas DFA letter rulings provide formal guidance and audit protection.

Common Pitfalls for B2B R&D Teams
Most Arkansas R&D sales tax errors fall into predictable patterns. Here are the five most common.
1. Assuming All R&D Is Exempt
R&D services are exempt. R&D property purchases are not — unless a specific exemption applies. Teams that have a blanket "R&D is exempt" assumption on their purchasing process often discover untaxed tangible purchases during audits.
2. Missing Use Tax on Out-of-State Equipment
Specialized scientific equipment often comes from out-of-state or international vendors. If the vendor does not collect Arkansas sales tax, you owe use tax at 6.5% on those purchases. Many R&D accounting teams handle federal and income tax carefully but overlook state use tax self-reporting.
3. Overclaiming the Manufacturing Exemption
Applying the manufacturing exemption to lab equipment that is not directly tied to production is a common audit issue. The exemption requires direct integration into the manufacturing process — not just proximity to manufacturing.
4. Conflating the R&D Income Tax Credit With Sales Tax Relief
The AEDC R&D tax credit program generates real income tax savings. It does not reduce the sales tax owed on R&D purchases. These are different tax types administered through different processes.
5. Not Requesting a Letter Ruling
When an R&D purchase sits in gray territory — especially chemicals, reagents, or equipment used across both research and production — a letter ruling from the Arkansas DFA provides formal guidance and insulates against audit liability. Most companies avoid this step because it takes time. Most companies that skip it pay more in audit settlements than the ruling would have cost.

How SyncGTM Fits In
Arkansas has a significant R&D sector — driven by agriculture, food science, biotech, logistics, and advanced manufacturing. Companies in these sectors are active B2B buyers. They purchase lab equipment, software platforms, contract research services, and technical tools at scale.
If your B2B team sells into this market — equipment suppliers, SaaS platforms, scientific distributors, contract research services — understanding R&D tax treatment helps you speak the buyer's language. Procurement teams at R&D-heavy companies are acutely aware of their tax position. Knowing whether your product is taxable (and what exemptions might apply) can accelerate purchasing decisions.
SyncGTM helps B2B sales and GTM teams identify which Arkansas companies run active R&D programs, what their technology stack looks like, and who the actual decision-makers are. Instead of cold prospecting into generic company lists, you can target accounts with known R&D budgets and buying signals.
The platform enriches company and contact data — pulling in technographic signals, funding data, and hiring patterns that indicate R&D activity. A company that just hired three biotech researchers and expanded its Benton County lab footprint is a different kind of prospect than one that posted a single science role six months ago.
Combined with automated outreach sequences, go-to-market execution into niche markets like Arkansas R&D becomes systematic rather than manual.

FAQ
Is research and development subject to sales tax in Arkansas?
R&D services are generally not subject to Arkansas sales tax because most services are exempt unless specifically listed as taxable. However, tangible personal property purchased for R&D — equipment, supplies, chemicals — is taxable at 6.5% unless a specific exemption applies, such as the manufacturing equipment exemption.
Can R&D equipment qualify for the Arkansas manufacturing exemption?
Only if the equipment is used directly in manufacturing a finished product for commercial sale. Equipment used solely in pre-production research or prototype development — without direct integration into the manufacturing process — does not qualify. Consult Arkansas DFA guidance or a tax advisor before claiming this exemption on R&D equipment.
Is SaaS used for research and development taxable in Arkansas?
No. Arkansas does not tax SaaS or electronically delivered software. If your R&D team uses cloud-based tools, analytics platforms, or hosted software, those subscriptions are not subject to Arkansas sales tax. Custom software built for a single user is also exempt.
What is the Arkansas R&D income tax credit and how is it different from a sales tax exemption?
The Arkansas R&D income tax credit offsets income tax liability — not sales tax. It provides 20%–33% credit on qualified research expenditures, depending on the program tier. It is administered by the Arkansas Economic Development Commission and requires a formal application. It does not reduce sales tax on R&D purchases.
Do Arkansas companies still pay use tax on R&D purchases from out-of-state vendors?
Yes. If you buy R&D supplies or equipment from an out-of-state vendor who does not collect Arkansas sales tax, you owe use tax at the same 6.5% rate. The use tax obligation applies whether the vendor is a national distributor or an online marketplace.
How does SyncGTM help B2B teams selling into the R&D sector?
SyncGTM enriches company and contact data so you can identify which Arkansas companies run R&D operations, what funding they have, and who the right buyers are. That means your outreach targets the actual economic buyers — not just generic marketing titles.
