Navigating the Kentucky Qualified Costs of Construction: An Expert Analysis of the R&D Facility Tax Credit (KRS 141.395)

I. Executive Summary: The Kentucky Qualified Research Facility Tax Credit

1.1 Defining Qualified Costs of Construction (QCC)

Qualified Costs of Construction (QCC) are capital expenditures made for building, expanding, remodeling, or equipping a facility located in Kentucky for the purpose of conducting R&D activities as defined by Internal Revenue Code (IRC) § 41. The credit is specifically limited to tangible, depreciable property and generates a nonrefundable tax credit equal to 5% of the total qualified costs.

1.2 Statutory Overview (KRS 141.395) and Purpose

The Kentucky Qualified Research Facility Tax Credit (QRFTC), governed by Kentucky Revised Statute (KRS) 141.395, functions as a powerful economic incentive aimed at stimulating substantial capital investment in research infrastructure within the Commonwealth.1 Unlike the federal R&D tax credit (IRC § 41), which primarily targets operational expenditures (OpEx) such as wages, supplies, and contract research, the Kentucky statute exclusively focuses on qualifying capital expenditures (CapEx) related to the physical development and equipping of research facilities.

The statute, which became effective on July 15, 2002, permits a credit against state tax liability for investments deemed “construction of research facilities”.2

1.3 Core Credit Mechanics

The QRFTC offers a highly effective and straightforward structure for businesses making qualified investments:

• Credit Rate: The allowable credit is a percentage-based calculation, equal to five percent (5%) of the total qualified costs of construction.1 A significant benefit unique to this state credit is that it requires no base calculation or comparison to prior-year spending. The entire eligible current-year QCC base fully qualifies for the 5% credit, significantly simplifying the calculation and maximizing the immediate return on investment compared to the complex incremental calculations required by federal rules.1
• Nonrefundable Nature: The credit is nonrefundable. This means it can only be used to offset existing tax liability; it will not generate a cash refund if the credit exceeds the tax owed.1
• Applicability and Ordering: The credit can be applied against multiple types of state taxes, specifically the Individual Income Tax (KRS 141.020), Corporation Income Tax (KRS 141.040), and the Limited Liability Entity Tax (LLET) (KRS 141.0401).6 Kentucky law includes specific credit ordering rules (KRS 141.0205) stipulating that the QRFTC must be utilized in a specific sequence, typically prioritizing application against the LLET before being applied against the Income Tax liability.6
• Carryforward: To ensure businesses have ample time to utilize the credit generated by large capital investments, any unused credit balance may be carried forward for up to ten (10) years.1

II. The Statutory Definition of Qualified Costs of Construction (QCC)

The authoritative scope of QCC is established by the statutory definition of “Construction of research facilities” under KRS 141.395, guidance consistently upheld by the Kentucky Department of Revenue (DOR) on Schedule QR instructions.3

2.1 Scope of “Construction of Research Facilities”

The term “Construction of research facilities” dictates four primary categories of qualifying investment, all of which must occur within the state of Kentucky and be dedicated to supporting qualified research:

1. Construction: Expenses associated with the physical erection of entirely new research buildings or specialized facilities.1
2. Expansion: Costs incurred to increase the physical footprint, size, or operational capacity of existing research facilities.1
3. Remodeling: Significant internal adaptation or structural renovation of existing spaces specifically undertaken to convert or upgrade them for qualified research activities.1
4. Equipping: Capital costs for the purchase and permanent installation of machinery, apparatus, laboratory equipment, and specialized testing gear necessary for the research function.1

2.2 The Depreciable Property Mandate: Tangible Assets Focus

The fundamental legal constraint on QCC is the requirement that the costs must include only tangible, depreciable property.3 This requirement establishes a direct link between the state credit and federal tax capitalization rules.

Analysis of “Tangible, Depreciable Property”

The property must meet strict federal criteria for capitalization:

• Tangibility: The asset must have a physical form. This excludes any purely intangible assets or routine service costs that are not capitalized into the tangible property’s basis.
• Depreciability: The cost must be eligible for depreciation under federal tax law, such as the Modified Accelerated Cost Recovery System (MACRS). Non-depreciable components, notably land acquisition and certain site preparation costs, are ineligible for the credit.7

This focus on depreciable capital assets means that taxpayers must rigorously classify their expenditures. The identification of property components that qualify for accelerated depreciation schedules (e.g., 5, 7, or 15-year property), rather than the standard 39-year recovery period for commercial real property, becomes a vital strategic tool for maximizing the QCC base. Through a Cost Segregation Study, businesses can isolate embedded assets—such as dedicated electrical systems, specialized plumbing, process utility lines, and environmental control systems—that are often mistakenly lumped into non-qualifying real property but are, in fact, integral to the research function and should be treated as qualifying tangible personal property.7

The Placed-in-Service Requirement

The tax credit is not available merely when the costs are incurred or paid; the statute dictates that the credit is claimable once the tangible, depreciable property is placed in service.3 This timing element is critical, as it requires the facility to be operational and ready for its intended use before the tax benefit can be realized. When claiming the credit, the taxpayer must provide documentation explicitly confirming the “date placed in service” for all claimed items.6

2.3 Critical Exclusions from QCC Eligibility

Compliance requires clear separation of qualifying capital costs from excluded expenses.

Exclusion of Replacement Property

The statute explicitly prohibits the inclusion of any amounts paid or incurred for replacement property.3 This provision is intended to prevent the credit from subsidizing routine capital maintenance or simple asset turnover. When remodeling or equipping a facility, the taxpayer must be prepared to demonstrate that the investment constitutes a new capability, capacity, or technological functionality required for the qualified research, rather than merely replacing an old asset with a new, functionally equivalent one. For example, upgrading an electrical grid to support a new high-powered testing machine would qualify, while replacing aging standard light fixtures would likely not.

Distinction from Federal Qualified Research Expenses (QREs)

Kentucky’s QCC is strictly a capital incentive, making it fundamentally different from the federal R&D credit, which targets operating expenses. Costs that are typically eligible for the federal IRC § 41 credit are explicitly excluded from the Kentucky QCC base.1 These operational costs include:

• Wages paid to employees directly conducting or supervising research.1
• Costs of supplies and raw materials consumed during experimentation.1
• Fees for contract research.1

The defining characteristic is the asset life: if the cost is expensed annually (OpEx), it is generally excluded from QCC. If it is capitalized and depreciated (CapEx), it may be included, provided it meets the facility and research requirements.

III. The IRC § 41 Linkage: Defining Qualified Research

The eligibility of the costs is inextricably linked to the definition of the activity conducted within the facility. Kentucky has fully adopted the federal standard, creating a vital legal and technical requirement.

3.1 Adoption of Federal Standards for Activity (IRC § 41)

Kentucky law defines “Qualified research” as “qualified research as defined in Section 41 of the Internal Revenue Code”.3 This means that the physical infrastructure supported by the QCC must be used for activities that satisfy the stringent federal criteria for R&D.

3.2 The Federal Four-Part Test

For construction or equipment costs to be “for qualified research,” the taxpayer must demonstrate that the activities performed within the facility satisfy all elements of the federal four-part test under IRC § 41(d) 8:

1. Section 174 Test (Permissible Expenditures): The expenditure must be of a type that could be treated as an expense under Section 174 (research or experimental expenditure in the experimental or laboratory sense).9
2. Technological Uncertainty Test (Purpose): The research must be undertaken for the specific purpose of discovering information that is technological in nature.
3. Business Component Test (Result): The application of the research must be intended to be useful in the development of a new or improved business component of the taxpayer.
4. Process of Experimentation Test (Method): Substantially all of the research activities must constitute elements of a process of experimentation intended to resolve technical uncertainty regarding the component’s functional design or operational methodology.

3.3 Strategic Contrast: Stacking the Benefits

The distinction between Kentucky’s focus on CapEx and the federal focus on OpEx provides a unique opportunity for businesses to “stack” credits. The state credit incentivizes permanent, physical infrastructure (the facility), while the federal credit incentivizes the ongoing activity (the labor and resources).

By ensuring the construction meets the definition of QCC and the activities conducted within meet the IRC § 41 definition of qualified research, a company can simultaneously claim the 5% Kentucky credit on the construction and equipment costs, while also claiming the federal R&D tax credit (often 10–20% of incremental qualified research expenses) on the associated wages and supplies.1 This structural differentiation ensures that businesses are rewarded for both the physical investment and the ongoing innovative effort.

IV. Kentucky Department of Revenue (DOR) Compliance and Guidance

The Kentucky Department of Revenue (DOR) specifies the exact mechanisms for reporting and claiming the QRFTC through standardized forms and mandatory documentation requirements.

4.1 Required Filing: Schedule QR (Form 41A720QR)

To claim the credit, the taxpayer—whether a corporation, partnership, LLC, or individual—must file Schedule QR, Qualified Research Facility Tax Credit (Form 41A720QR), which is attached to the appropriate state income tax return (e.g., Form 720 for Corporations, Form 740 for Individuals).6

Computation of Allowable Tax Credit (Schedule QR, Part I)

Part I of Schedule QR requires the taxpayer to clearly define and calculate the QCC base 3:

• Line 1 (Cost of Construction): This line captures the costs related to the depreciable facility structure, including remodeling, expansion, and new construction.
• Line 2 (Cost of Equipment): This line captures the capitalized costs of machinery, apparatus, and equipment placed into the facility.
• Line 3 (Total Qualified Costs): The sum of Lines 1 and 2, representing the total QCC base.
• Line 4 (Allowable Tax Credit): The final credit amount, calculated as 5% (.05) of the Total Qualified Costs (Line 3).3

Credit Application and Carryforward Tracking (Schedule QR, Parts II and III)

The balance of the credit must be tracked meticulously across tax years. Schedule QR provides space to record the credit balance, the amount utilized against LLET and Income Tax in the current year, and the remaining carryforward balance.10 The statute mandates that the credit be applied against the LLET first, and then against the income tax.6 A copy of the Schedule QR must be submitted with the tax return each year the credit is claimed until the balance is fully utilized or the 10-year carryforward window has closed.3

4.2 Mandatory Supporting Documentation

The DOR places significant emphasis on documenting the nature and timing of the capitalized costs. Taxpayers must include a supporting schedule detailing the tangible, depreciable property included in Lines 1 and 2 of Schedule QR.6

The supporting schedule must list four specific data points for each item of property:

1. Date Purchased
2. Date Placed in Service
3. Description (Clearly identifying the tangible, depreciable property)
4. Cost

The requirement for the specific “date placed in service” is crucial for substantiating the timing of the claim. Furthermore, the property description must be detailed enough to prove the asset’s depreciable nature and its direct link to the qualified research activities, differentiating specialized laboratory installations from general, non-qualifying property.

4.3 Pass-Through Entity Rules

The credit is fully accessible to pass-through entities, ensuring that the incentive structure reaches a wide array of Kentucky businesses.

• Eligibility: Corporations, partnerships, LLCs, and individuals (including sole proprietors reporting on Schedule C) may claim the credit.1
• Pass-Through Mechanics: For partnerships, S-Corporations, and LLCs taxed as partnerships, the entity calculates the total credit base and allowable credit (Line 4 of Schedule QR). This credit then flows through to the partners, members, or shareholders via a Kentucky Schedule K-1.1 These individuals may then claim the credit against their individual Kentucky income tax liability, provided the underlying facility was constructed for qualified research purposes.6

V. Practical Example and Calculation Case Study

To illustrate the application of QCC rules, the following example details the facility expansion of a Kentucky-based firm.

5.1 Scenario Setup: Commonwealth Composites Research Lab

Commonwealth Composites, a Kentucky C-Corporation, completed a $3.0 million expansion project to construct a new materials testing lab used for activities qualifying under IRC § 41. The project was placed in service on December 1, 2023.

The total expenditures were analyzed for QCC eligibility:

The Total Qualified Costs of Construction (QCC) for this project are calculated as:

$$\$1,800,000 + \$400,000 + \$500,000 + \$150,000 = \$2,850,000$$

5.2 Calculation of Allowable Credit

Commonwealth Composites uses Schedule QR to compute the allowable credit for Tax Year 2023.

5.3 Application of Credit and Carryforward

Assume Commonwealth Composites has a total 2023 Kentucky tax liability of $130,000, broken down as $30,000 in LLET and $100,000 in Corporate Income Tax.

1. LLET Application: The credit must first offset the LLET. $142,500 (Credit) offsets $30,000 (LLET).
2. Income Tax Application: The remaining credit balance ($142,500 – $30,000 = $112,500) then offsets the Corporate Income Tax. $112,500 (Remaining Credit) offsets $100,000 (Income Tax).
3. Total Utilization: The firm uses $30,000 + $100,000 = $130,000 of the credit in 2023.
4. Carryforward: The remaining credit balance of $12,500 ($142,500 – $130,000) is carried forward for up to 10 years (until Tax Year 2033).2 The firm must file a copy of Schedule QR annually to track and claim this remaining balance.3

VI. Conclusion

The Kentucky Qualified Research Facility Tax Credit (QRFTC) provides a specialized, nonrefundable incentive calculated at 5% of Qualified Costs of Construction (QCC). This credit is distinct in its singular focus on capital expenditures for R&D infrastructure, demanding adherence to clear statutory boundaries established by KRS 141.395.

The successful capture and defense of this credit necessitate strict adherence to the definition of QCC: the expenditure must result in tangible, depreciable property located in Kentucky and be utilized for activities meeting the definition of qualified research under IRC § 41. Exclusions are equally crucial; non-depreciable items, replacement property, and operational costs like wages are strictly prohibited from the QCC base.

Optimal tax planning requires a sophisticated approach to asset classification, often involving cost segregation to maximize the base by properly classifying specialized electrical systems, equipment, and structural components as depreciable assets eligible for the credit. Furthermore, the taxpayer must maintain rigorous documentation, filing Schedule QR annually and attaching the required supporting schedule detailing the asset’s purchase date, cost, description, and, most importantly, the date placed in service, as this dictates when the credit can first be claimed.

By navigating these specific requirements, businesses investing in research facilities can effectively stack the Kentucky QRFTC with the federal R&D tax credit, yielding significant, long-term returns on their capital investment in innovation within the Commonwealth.
