Depreciable Tangible Personal Property (Sales Tax Exemption)

Depreciable tangible personal property in the Texas Research and Development context refers to physical assets with a useful life exceeding one year that are subject to depreciation under federal tax or accounting standards. These items are exempt from sales and use tax when used directly in the performance of qualified research activities as defined by the Internal Revenue Code.

The Statutory Genesis and Evolution of Texas Research and Development Incentives

The fiscal landscape of Texas has historically been defined by its reliance on consumption-based taxes rather than personal or corporate income taxes. Within this framework, the Texas Legislature has utilized targeted exemptions and credits to incentivize high-value industrial activities. The primary statutory mechanism for fostering innovation is found in the Research and Development (R&D) incentive package, which was significantly revitalized by House Bill 800 during the 83rd Legislative Session in 2013. This legislation introduced a bifurcated system of incentives, codified primarily in Chapter 151 of the Texas Tax Code for sales and use tax exemptions and Chapter 171 for franchise tax credits. This structure allowed a person engaged in qualified research to claim either a sales and use tax exemption on the purchase, lease, rental, storage, or use of depreciable tangible personal property directly used in qualified research or a franchise tax credit based on qualified research expenses.

The implementation of these incentives reflects a strategic alignment with federal standards, specifically referencing the Internal Revenue Code (IRC) of 1986. Under Section 151.3182, the state provides a clear pathway for entities to reduce the capital intensity of their research operations by exempting the 6.25 percent state sales tax and applicable local taxes on the equipment necessary for the process of experimentation. This exemption is predicated on a “strict construction” principle, common in Texas jurisprudence, which requires that tax exemptions be narrowly interpreted and that the claimant bear the burden of proof by clear and convincing evidence. The policy objective, as articulated in legislative analyses, is to keep Texas economically competitive with the approximately 29 other states that offer similar R&D incentives, thereby encouraging new investments and the creation of high-paying jobs.

Conceptualizing Depreciable Tangible Personal Property

To navigate the Texas R&D exemption, one must first master the definition of depreciable tangible personal property (TPP). Tangible personal property is broadly defined under Section 151.009 as personal property that can be seen, weighed, measured, felt, or touched, or that is perceptible to the senses in any other manner. For the purpose of the R&D exemption, however, the TPP must also be “depreciable,” a term that carries specific legal and accounting weight. The statute defines depreciable TPP as property that has a useful life exceeding one year and is subject to depreciation under either Generally Accepted Accounting Principles (GAAP) or the Internal Revenue Code, specifically Sections 167 or 168, as they were in effect on December 31, 2011.

A critical nuance in this definition is that the property does not actually have to be depreciated on the taxpayer’s books or tax returns to qualify; it merely must be “subject to” the allowance for depreciation. This is particularly relevant for startups or pre-revenue companies that may not yet be recording depreciation expenses for federal income tax purposes but are purchasing high-value capital assets for research. Furthermore, the inclusion of GAAP as an alternative standard provides flexibility for entities using different financial reporting frameworks. For federal purposes, a depreciation deduction is generally considered a reasonable allowance for the exhaustion, wear and tear, and obsolescence of business-related or income-producing property.

The Scope of Tangible Assets in the Research Environment

The categorization of property as depreciable TPP excludes consumable supplies and materials that are used or exhausted within the first year of their use. While these consumables may qualify as Qualified Research Expenses (QREs) for the franchise tax credit—specifically as “in-house research expenses” under IRC Section 41(b)(2)—they are inherently ineligible for the sales tax exemption under Section 151.3182. This creates a sharp distinction in the tax treatment of research inputs: heavy machinery, specialized computers, and laboratory instruments are the primary candidates for the sales tax exemption, while chemical reagents, test tubes, and other short-lived supplies are better suited for the franchise tax credit.

Software as Tangible Personal Property

The treatment of computer software under Texas tax law is a complex but vital component of the R&D exemption. The Comptroller’s office has long maintained that the sale, lease, or license of a computer program is a sale of tangible personal property. Consequently, software used in research can qualify as depreciable TPP if it has a useful life of more than one year. However, the distinction between “canned” (off-the-shelf) software and “custom” software has largely been erased for sales tax purposes since 1987; all computer programs purchased after October 1, 1987, are considered TPP.

For the R&D exemption, software must satisfy the Internal Use Software (IUS) rules if it is not developed to be commercially sold, leased, or licensed to third parties. Under the Treasury Regulations incorporated by the Comptroller, IUS must meet a “high threshold of innovation” to be considered qualified research, meaning the software is innovative, involves significant economic risk, and is not commercially available. If these hurdles are cleared, the purchase of software licenses or the hardware to run them may be made tax-free under Section 151.3182, provided the software is “directly used” in the process of experimentation.

The Doctrine of “Direct Use” and Administrative Guidance

The most rigorous requirement of the R&D sales tax exemption is that the depreciable TPP must be “directly used” in qualified research. The Comptroller’s office provides a precise definition for this term: “directly” means having an immediate effect on an item or in an activity, without an intervening, ancillary, or prior effect. This definition serves to isolate the core experimental activity from the general business and support functions that surround it.

Examples of Direct Use Property

Texas Administrative Code (TAC) Section 3.340(b)(1)(D) provides an illustrative, though not exhaustive, list of items that qualify as being directly used when employed by personnel in the process of experimentation:

• Machinery and Equipment: Large-scale devices such as specialized manufacturing equipment used to test new production processes.
• Computers and Software: Hardware and programs used to model physical phenomena, run simulations, or manage experimental data.
• Specialized Tools: Gauges, meters, and other instruments used to measure and verify research outcomes.
• Laboratory Furniture: This is a notable inclusion, as laboratory furniture—including desks, tables, stools, benches, and storage cabinets—is considered directly used when it facilitates the experimental process. This represents a broader interpretation than the manufacturing exemption, which often excludes such “ancillary” furniture.

Exclusions and Non-Qualifying Uses

Property used in activities that support research but are not “the research itself” are disqualified from the exemption. This includes equipment used in:

• Administrative and Clerical Functions: Computers and printers used for accounting, human resources, or general management of the research facility.
• General Business Operations: Property used in marketing, sales, distribution, or transportation activities.
• Maintenance and Janitorial Services: Equipment used to clean or maintain the building or the research environment, such as floor scrubbers or general HVAC systems.
• Transportation: Intra-plant transportation equipment used to move materials or products, unless specifically integrated into a single item of exempt equipment.

The principle of “immediate effect” is the litmus test. If a piece of equipment is used to create the environment where research happens (like lighting or general climate control), it is usually considered ancillary. If the equipment is used to manipulate the variables of the experiment (like a climate-controlled test chamber), it is considered directly used.

Defining Qualified Research: The Nexus with Federal Law

For the purposes of the Texas exemption, the property must be used in “qualified research” as defined by Section 41 of the Internal Revenue Code. This definition is anchored to the IRC as it existed on December 31, 2011. To meet this definition, a research project must satisfy a rigorous Four-Part Test, and the activity must not fall into any of the statutory exclusions.

The Four-Part Test for Qualified Research

1. The Section 174 Test (Elimination of Uncertainty): The research must be intended to discover information that would eliminate uncertainty concerning the development or improvement of a business component. Uncertainty exists if the information available to the taxpayer does not establish the capability or method for developing or improving the business component, or the appropriate design of the business component.
2. The Discovering Technological Information Test: The research must be undertaken to discover information that is technological in nature. The process of experimentation must fundamentally rely on principles of the physical or biological sciences, engineering, or computer science.
3. The Business Component Test: The taxpayer must intend to use the information discovered to develop a new or improved business component. A business component is defined as any product, process, computer software, technique, formula, or invention to be held for sale, lease, or license, or used by the taxpayer in their trade or business.
4. The Process of Experimentation Test: Substantially all of the research activities must constitute a process of experimentation. This involves the identification of alternative designs or models, the evaluation of those alternatives, and the systematic testing and refining of hypotheses. In this context, “substantially all” is generally interpreted to mean 80 percent or more of the activities.

Activities Excluded from the Definition

State and federal law explicitly exclude several categories of activity from the definition of qualified research. Property used in these activities is not eligible for the sales tax exemption:

• Post-Commercial Production Research: Any research conducted after the business component has been released for commercial production or use.
• Adaptation of Existing Products: Activities focused on adapting an existing business component to a particular customer’s requirement or need.
• Duplication and Reverse Engineering: The reproduction of an existing business component, in whole or in part, from a physical examination, plan, blueprint, or specification.
• Surveys and Studies: Efficiency surveys, management studies, consumer surveys, market research, or routine data collection.
• Internal Use Software (General): Software developed for use in general and administrative functions, unless it meets the high threshold of innovation.
• Funded Research: Research to the extent it is funded by any grant, contract, or otherwise by another person or governmental entity.

The Administrative Lifecycle: Registration and Compliance

The Texas Comptroller of Public Accounts maintains a strict administrative regime for the R&D sales tax exemption. A taxpayer cannot simply claim the exemption at the point of sale without prior authorization.

Registration Requirements (Form AP-234)

Before claiming the exemption, a person must register with the Comptroller’s office to obtain a Texas Qualified Research Registration Number. This is accomplished by filing Form AP-234, the “Texas Registration for Qualified Research and Development Sales Tax Exemption”. During the registration process, the taxpayer must provide several data points:

• The 11-digit Texas taxpayer number, Secretary of State file number, or 9-digit federal identification number.
• The total amount of all purchases in Texas that qualify for the exemption.
• The total amount of all qualified research expenses in Texas.
• The number of full-time and part-time employees engaged in qualified research in the state.
• Payroll expenses for those R&D employees.

A crucial component of the registration is the Mandatory Certification. The taxpayer must certify that it will not, as a taxable entity or as a member of a combined group, claim a franchise tax research credit on a franchise tax report for the period during which the depreciable TPP would first be subject to Texas sales or use tax.

Claiming the Exemption (Form 01-931)

Once registered, the taxpayer may purchase qualifying property tax-free by providing the seller with Form 01-931, the “Texas Qualified Research Sales and Use Tax Exemption Certificate”. This certificate must include the registrant’s registration number and be signed by an authorized agent. While a retailer is not strictly required to verify the number, they may use the Comptroller’s online system to do so. If the purchaser fails to provide a properly completed certificate at the time of purchase, the retailer is legally required to collect sales tax.

The Annual Information Report (AIR)

Every registrant is required to submit an Annual Information Report (AIR) for each calendar year their registration is effective. This report is due by March 31 of the following year. The report must be submitted electronically unless the Comptroller issues a waiver due to hardship. The AIR provides the data the Comptroller needs to evaluate the economic effect of the exemption on state tax revenues, employment, and economic activity. Failure to file the AIR in a timely manner can result in the cancellation of the registration number.

Retroactive Registration and Refunding Paid Taxes

The law allows for retroactive registration back to the later of January 1, 2014, or a date up to four years prior to the registration date. To obtain a retroactive registration, the taxpayer must file an AIR for each of the prior years in the retroactive window. Once the retroactive number is issued, the registrant may file a claim for a refund of Texas sales and use tax paid on qualifying purchases made during that period.

Inter-Entity Transactions and Group Conflicts

A significant area of tension in Texas tax administration involves research activities conducted by related entities. Under federal law, all members of a “group under common control” are treated as a single taxpayer for purposes of determining the research credit. However, the Texas Comptroller has explicitly rejected this “single taxpayer” theory for the sales tax R&D exemption.

In a pivotal Private Letter Ruling (PLR 20221109154351), the Comptroller addressed a situation where a subsidiary purchased items that were used by its parent company in the parent’s research activities. The Comptroller ruled that the subsidiary could not use the parent’s registration number or the parent’s research activities to make tax-free purchases. The ruling established several key principles:

• The person claiming the benefit of the exemption must be the person who is actually using the property in qualified research activities.
• Exemptions from taxation must be strictly construed against the taxpayer.
• The “sale-for-resale” exemption does not apply unless the items are transferred to the parent in the same form or condition in which they were acquired.

This creates a substantial compliance burden for large corporate groups. If a central procurement entity buys equipment for use by multiple R&D-performing subsidiaries, the exemption may be lost unless the procurement entity itself is also engaged in the research or if a formal leasing arrangement is established that satisfies the “rental” provisions of Section 151.3182.

Divergent Use and Recapture of Exempted Taxes

If a taxpayer purchases an item tax-free under a valid R&D exemption certificate but later uses that item in a taxable manner—meaning for a purpose other than qualified research—the taxpayer becomes liable for tax, penalties, and interest. This is known as “divergent use.”

Calculating the Recapture

The tax liability for divergent use is typically based on the fair market rental value of the property for the period of time it was used for non-exempt purposes. This allows the taxpayer to keep the portion of the tax benefit corresponding to the exempt research use while paying the state for the period of non-exempt use. However, if the exemption certificate was “invalid at the time of its issuance”—for example, if the taxpayer was never actually engaged in qualified research—then tax, penalty, and interest are due on the original full purchase price.

The fair market rental value is often determined through comparable lease analysis or, if such data is unavailable, by applying a market rate of return to the appraised market value of the property. Taxpayers who routinely use equipment in both exempt and non-exempt manners may elect to pay tax based on a “divergent use percentage” rather than tracking every individual use.

The Strategic Choice: Sales Tax Exemption vs. Franchise Tax Credit

One of the most critical decisions for a Texas business is the election between the sales tax exemption and the franchise tax credit. A taxpayer cannot claim both for the same period. This election is not permanent and can be changed annually.

Comparing the Values

The franchise tax credit is generally calculated as 5 percent of the difference between the qualified research expenses incurred in the current period and 50 percent of the average QREs from the three preceding tax periods. If the entity has no QREs in one or more of the prior three years, the credit is 2.5 percent of current QREs.

The sales tax exemption, by contrast, provides an immediate 6.25 percent (plus local) savings on the full purchase price of depreciable equipment.

Decision Factors

• Capital Intensity: If a company is in a heavy “build-out” phase, purchasing millions of dollars in lab equipment or server hardware, the sales tax exemption provides immediate cash flow benefits.
• Labor Intensity: If a company’s primary research cost is developer or engineer salaries, the franchise tax credit is likely more valuable, as wages do not qualify for the sales tax exemption.
• Profitability and Tax Liability: The franchise tax credit is limited to 50 percent of the franchise tax due for the report. If a company has no franchise tax liability, the credit must be carried forward (for up to 20 years). The sales tax exemption, however, provides a benefit at the moment of purchase regardless of the company’s franchise tax status.

The 2025 Legislative Overhaul: Senate Bill 2206

A fundamental shift in the Texas R&D landscape occurred on June 22, 2025, when Governor Greg Abbott signed Senate Bill 2206 into law. This legislation represents the most significant change to the state’s innovation incentives since their inception.

Repeal of the Sales Tax Exemption

Effective January 1, 2026, the sales and use tax exemption for depreciable property used in research (Texas Tax Code Section 151.3182) is repealed. Taxpayers will no longer have the option to make tax-exempt purchases of R&D equipment. This repeal was driven by the legislature’s desire to streamline tax administration and eliminate the “inefficiency” of the elective system.

The New Permanent Franchise Tax Credit

To compensate for the loss of the sales tax exemption, SB 2206 establishes a new, permanent, and significantly expanded franchise tax credit, recodified in Subchapter T of Chapter 171. The new credit marks an approximately 75 percent increase in the incentive amount.

Refundability for Small Businesses and Startups

One of the most revolutionary changes in SB 2206 is the introduction of refundability. Historically, the R&D credit was only useful as an offset against taxes owed. Under the new law, certain entities that owe no franchise tax are entitled to receive the credit as a cash refund. These entities include:

1. New Veteran-Owned Businesses.
2. Small Businesses with total revenue below the “no-tax-due” threshold (currently $2.47 million).
3. Low-Tax Entities whose computed tax is less than $1,000.

This change ensures that pre-revenue startups and small innovators can access the incentive immediately, serving as a form of non-dilutive capital.

Rolling Conformity to Federal Law

The new law also moves away from the “fixed-date” conformity of the past. The Texas R&D credit calculation will now follow federal law as it is in effect for the federal tax year for which the credit is claimed. Furthermore, the definition of QREs is tied directly to the amount reported on Line 48 of Federal Form 6765, which significantly simplifies the documentation process for taxpayers and the audit process for the Comptroller.

Practical Application: A Multi-Phase Research Project Example

To demonstrate how the depreciable TPP exemption applies in practice—and how the transition to the 2026 law affects strategy—consider the case of “AeroDynamics Texas,” a firm developing a new hydrogen-powered drone engine.

Phase 1: Capital Build-Out (Fiscal Year 2024)

In 2024, AeroDynamics Texas spends $2,000,000 on high-value equipment:

• A $1,200,000 wind tunnel with a 10-year useful life (Depreciable TPP).
• $500,000 in high-performance workstations for computational fluid dynamics (Depreciable TPP).
• $200,000 in specialized sensors and telemetry devices with a 2-year life (Depreciable TPP).
• $100,000 in office furniture for the administrative staff (Non-Qualifying).

Sales Tax Application:

AeroDynamics registers with the Comptroller and receives a registration number. They provide Form 01-931 to their vendors.

• Wind Tunnel: Exempt (Savings: $1,200,000 * 8.25% = $99,000).
• Workstations: Exempt (Savings: $500,000 * 8.25% = $41,250).
• Sensors: Exempt (Savings: $200,000 * 8.25% = $16,500).
• Office Furniture: Taxable ($100,000 * 8.25% = $8,250 paid).

Total 2024 Sales Tax Savings: $156,750.

Trade-off: The company cannot claim a 2024 franchise tax credit for its R&D wages.

Phase 2: Intensive Testing (Fiscal Year 2026)

In 2026, the law has changed. AeroDynamics spends another $500,000 on equipment and $3,000,000 on engineer wages.

The 2026 Calculation:

The sales tax exemption is gone. AeroDynamics pays $41,250 in sales tax on the equipment. However, they now claim the expanded franchise credit.

The credit is calculated using the incremental formula: Credit = 0.08722 * (Current QREs – (0.5 * Average Prior 3-Year QREs))

Assume the average QREs from 2023-2025 were $2,000,000.

• Current QREs: $3,500,000 ($3M wages + $0.5M equipment).
• Base Amount: 0.5 * $2,000,000 = $1,000,000.
• Incremental Difference: $3,500,000 – $1,000,000 = $2,500,000.
• Total Credit: $2,500,000 * 0.08722 = $218,050.

Strategic Result: While the company had to pay $41,250 in sales tax upfront, they received a $218,050 credit—more than triple the old 5% rate credit ($125,000). If the company’s revenue is low enough, they can receive this $218,050 as a cash refund from the state.

Strategic Implications and Risk Management

For taxpayers navigating this transition, several second-order considerations emerge regarding documentation, inter-company structuring, and the timing of capital expenditures.

Documentation and the Burden of Proof

The “clear and convincing evidence” standard required by the Comptroller for tax exemptions is higher than the “preponderance of evidence” standard used in most civil litigation. Taxpayers must maintain contemporaneous business records that support the qualified nature of the research and the direct use of each piece of property. This includes:

• Project logs and experimental plans that link specific equipment to the process of experimentation.
• Asset ledgers showing the useful life and depreciation method for each item.
• Employee time tracking that separates R&D hours from administrative or sales hours.
• Vendor invoices that clearly describe the items purchased and the date of sale.

The “Shelf-Life” of Current Exemptions

Businesses planning significant capital investments in R&D equipment should consider accelerating those purchases into the 2024 or 2025 calendar years. By finalizing purchases before the December 31, 2025, expiration of Section 151.3182, companies can lock in the immediate sales tax savings. Purchases made on or after January 1, 2026, will be subject to sales tax, and the benefit will only be recoverable through the franchise tax credit system in the following year.

Transitioning Carryforwards

The repeal of the old R&D credit and sales tax exemption does not affect unused credits already earned under the old law. Taxpayers may continue to carry forward these credits for the remainder of their original 20-year window. When applying credits to a franchise report, taxpayers must follow a specific order of operations:

1. Subchapter O carryforwards (the pre-2008 credits).
2. Subchapter M carryforwards (the 2014-2025 credits).
3. New Subchapter T current year credits.

This “First-In, First-Out” approach ensures that the oldest credits—which are closest to expiration—are used first, protecting the taxpayer’s long-term tax assets.

Final Thoughts

The meaning of depreciable tangible personal property within the Texas R&D framework is inextricably tied to the broader goal of making Texas a sanctuary for high-technology development. By defining qualifying property through the lens of longevity and “directness,” the state has created a targeted incentive for the physical tools of innovation. However, the complexity of administrative registration, the strict construction of inter-entity transactions, and the rigorous definitions of qualified research mean that the exemption is only accessible to those with sophisticated tax compliance systems.

The move to a permanent, enhanced, and potentially refundable franchise tax credit in 2026 signifies a maturity in Texas’s tax policy. It acknowledges that for many modern innovators—particularly those in software and biotech—the most significant costs are human capital and data processing, which are not captured by a sales tax exemption on physical hardware. While the loss of the immediate sales tax exemption may cause a temporary cash-flow adjustment for equipment-heavy sectors, the significantly higher credit rates and the removal of the non-refundability barrier for small businesses represent a more equitable and robust support system for the Texas innovation economy. Professionals in the field must now shift their focus from the point-of-sale exemption to the rigorous documentation of Qualified Research Expenses on federal Form 6765, as this will become the primary engine of R&D tax benefits in the Lone Star State for the foreseeable future.
