The Definitive Guide to Date Placed in Service for the Kentucky Qualified Research Facility Tax Credit
The Date Placed in Service (DPIS) represents the exact moment when tangible, depreciable property is ready and available for its intended use in a trade or business. For the Kentucky Qualified Research Facility Tax Credit, this specific date is the definitive trigger that determines the tax year in which the nonrefundable credit is generated and becomes eligible for application against state tax liability.
This temporal marker is foundational to tax compliance and strategy, governing the realization of both federal depreciation deductions and the specialized 5% state credit provided under Kentucky Revised Statute (KRS) 141.395. The analysis presented here details the intersection of federal depreciation law with Kentucky’s unique facility credit structure, clarifying the mandates imposed by the Kentucky Department of Revenue (DOR) regarding timing and documentation.
The Kentucky QRFTC Landscape: Scope and Purpose (KRS 141.395)
The Commonwealth of Kentucky provides a significant tax incentive intended to spur capital investment in research infrastructure within the state. This incentive, the Qualified Research Facility Tax Credit (QRFTC), is codified under KRS 141.395.1
Statutory Authority and Credit Structure
The Kentucky QRFTC offers a nonrefundable income tax credit equal to five percent (5%) of the qualified cost incurred for the “construction of research facilities”.1 This credit can be applied against income taxes imposed by KRS 141.020 (individual income tax) or KRS 141.040 (corporation income tax), as well as the Limited Liability Entity Tax (LLET) imposed by KRS 141.0401.3
Unlike the federal Section 41 Research & Development (R&D) credit, which primarily targets operational expenses such as qualified wages and supplies, the Kentucky incentive is narrowly focused on capital expenditures related to infrastructure. “Construction of research facilities” encompasses constructing, remodeling, expanding, and equipping facilities physically located in Kentucky that are dedicated to qualified research activities.3 Critically, the qualified costs include only tangible, depreciable property and explicitly exclude any amounts paid or incurred for replacement property.2
Overview of DPIS in State Credit Generation
The DPIS date provides the essential bright-line rule for determining compliance and timing. It marks the investment’s transition from a capital expenditure still under construction to an eligible asset capable of generating a tax credit.1 The statutory emphasis on this date establishes that the availability of the credit is tied to the asset’s functional readiness, overriding the timing of costs incurred or payments made.
Kentucky adheres to an authoritative availability standard for credit generation. This means that a taxpayer may have paid for an asset entirely in Year 1, but if the facility or equipment is not ready for use until Year 2, the tax credit is not generated until the Year 2 tax return.1 This mechanism necessitates that tax planning align closely with operational and engineering project timelines, confirming functional completion rather than relying solely on financial ledgers.
The Federal Foundation: Defining Depreciable Property and DPIS
Kentucky’s credit relies on the classification of property as “tangible, depreciable property,” a concept rooted firmly in federal tax law, specifically the Internal Revenue Code (IRC). Understanding the federal context of DPIS is mandatory for state compliance.
Depreciation and Cost Recovery Mechanics (IRC § 167/§ 168)
Under federal law, the cost of property acquired, produced, or improved for use in a trade or business must generally be recovered over time through depreciation, as these costs are considered capital expenditures.5 The DPIS is the critical date for initiating this cost recovery. The Internal Revenue Service (IRS) defines DPIS as the date when the property is placed in a condition or state of readiness and availability for its specifically assigned use.5
For sophisticated research facilities, DPIS is reached when the physical infrastructure is complete, essential utilities (such as specialized power feeds, exhaust systems, or temperature controls necessary for research) are fully operational, and the equipment can successfully begin supporting the qualified research activities defined under IRC Section 41.5 Property eligible for accelerated deductions, such as Section 179 expensing or special depreciation allowances (bonus depreciation), must also meet this DPIS criterion in the year the deduction is claimed.5
Federal Implications of DPIS Timing
The timing of DPIS holds significant federal implications, particularly regarding accelerated depreciation. For example, property placed in service in 2024 may be eligible for a higher percentage of bonus depreciation (e.g., 60%) compared to property placed in service in 2025 (e.g., 40%).6 If the DPIS date for a piece of equipment is determined to be December 31, 2024, versus January 1, 2025, the taxpayer benefits from the higher bonus depreciation rate and the immediate reduction in federal taxable income in the earlier tax year.6
This dynamic creates a strategic necessity for tax planning: a successful DPIS strategy achieves a simultaneous optimization. By confirming DPIS before year-end, the taxpayer maximizes the federal tax deduction (lowering income) and simultaneously secures the generation of the 5% Kentucky state tax credit (lowering tax liability). This synergistic benefit requires rigorous, multi-jurisdictional coordination during the final stages of asset installation and construction. If an asset’s readiness is delayed into the subsequent year, the taxpayer not only postpones the Kentucky credit claim but may also lose out on the maximum potential federal bonus depreciation benefit due to federal phase-down schedules.
Alignment with Qualified Research (IRC § 41)
The Kentucky QRFTC explicitly requires that the facility support “qualified research as defined in Section 41 of the Internal Revenue Code”.3 This ensures that the underlying investment is aligned with the rigorous federal definition, which typically requires activities to meet a four-part test: the activity must be technological in nature, performed for a permitted purpose (improving function or quality), intended to eliminate technical uncertainty, and involve a process of experimentation.2 This statutory link confirms that Kentucky’s focus is on infrastructure supporting high-value R&D activities, not general business expansion.
Kentucky Statutory Framework: Qualified Research Facilities
The Kentucky statute establishes specific rules regarding eligible investments and stringent exclusions that depend heavily on the proper classification and documentation of the DPIS.
KRS 141.395 and “Construction of Research Facilities”
Qualified costs must be directly related to the construction, remodeling, equipping, or expansion of in-state facilities used for qualified research.3 Only costs associated with tangible, depreciable property qualify for the 5% credit.2 This includes permanent fixtures, specialized construction improvements, and equipment necessary for the research operations.
Specific Exclusion: Replacement Property and Audit Risk
A crucial limiting factor in the Kentucky statute is the explicit exclusion of “any amounts paid or incurred for replacement property”.1 Kentucky’s legislative intent is clearly to incentivize net new investment and growth in research capacity.
The mandated documentation of both the date purchased and the date placed in service 3 provides the DOR with the necessary tools to enforce this exclusion effectively during an audit. By comparing the DPIS and description of the newly claimed asset against the taxpayer’s existing property records, the DOR can identify costs associated with routine asset swaps rather than true expansion. Therefore, if a new asset is placed in service shortly after a similar asset is retired, the taxpayer must be able to substantiate that the new property represents a net increase in functional capacity or performance, thereby mitigating the risk of the cost being disallowed as replacement property.
Credit Utilization and Separate Tax Liabilities
The Kentucky QRFTC is nonrefundable, meaning it cannot result in a refund to the taxpayer; however, any unused credit may be carried forward for a period of ten (10) years.1
A complexity unique to Kentucky tax law involves the application of the credit against separate tax streams: Income Tax (KRS 141.020/141.040) and the Limited Liability Entity Tax (LLET) (KRS 141.0401). Taxpayers must calculate the credit claimed and the resulting balance available separately for each tax liability.4 For example, any balance available for the LLET cannot be used as a credit against the Income Tax liability, nor vice versa.4 The credit applied against the LLET is further limited as it cannot reduce the LLET liability below the statutory minimum of $175.1 This non-fungibility requires specialized long-term financial modeling to ensure that credits generated through capital investment are fully utilized before the 10-year carryforward period expires.
The Critical Nexus: DPIS as the Credit Generation Trigger
The relationship between DPIS and the QRFTC is direct and absolute: the DPIS date is the single factor that determines the year the credit is created and available for claim.
Timing Mandate: DPIS Determines the Tax Year of Claim
Kentucky administrative guidance explicitly confirms that the credit is generated and available “once the tangible, depreciable property is placed in service”.4 This generation timing is independent of the timing of the construction expenditures themselves. If a major facility is constructed over three years, with costs paid in Years 1, 2, and 3, but the facility and equipment are not fully ready for use until Year 3, the entire corresponding credit is generated in Year 3.1
Commencement of the 10-Year Utilization Window
The DPIS date is the effective start date of the 10-year credit expiration clock. This fact carries significant administrative weight for taxpayers undertaking phased construction projects.
If a company expands its research facility in discrete stages over several years, each stage (or “project”) placed in service in a different tax year creates a legally distinct pool of nonrefundable credit. For instance, assets placed in service in 2024 generate a credit that expires at the end of the 2034 tax year, while assets placed in service in 2025 generate a separate credit pool that expires at the end of the 2035 tax year.3 Tax tracking systems must maintain this high level of granularity, capable of distinguishing credit carryforward balances based on the specific generation year and managing the dual application against LLET and Income Tax to prevent credit expiration.
Critical Distinction: DPIS Role in Federal Depreciation vs. Kentucky Credit Generation
The DPIS serves distinct, though interconnected, functions in federal and state tax reporting, highlighting why meticulous tracking is essential.
Table Title: Critical Distinction: DPIS Role in Federal Depreciation vs. Kentucky Credit Generation
| Feature | Federal Depreciation (IRC) | Kentucky QRFTC (KRS 141.395) |
| Primary Trigger | Commencement of cost recovery and determination of bonus/Section 179 eligibility.5 | Generation of the 5% tax credit based on qualified facility costs.1 |
| Financial Benefit Type | Tax Deduction (Reduces Taxable Income). | Nonrefundable Tax Credit (Direct reduction of Tax Liability).1 |
| Utilization Constraint | Governed by MACRS useful life and taxable income limitations. | Governed by a strict 10-year carryforward limit from the DPIS year, applied separately against LLET and Income Tax.2 |
| Documentation Link | Form 4562 and depreciation schedules. | Schedule QR and the supporting schedule listing DPIS, cost, and description.3 |
Kentucky Department of Revenue (DOR) Guidance and Compliance
The Kentucky DOR’s guidance emphasizes stringent documentation requirements centered on substantiating the DPIS date for every eligible asset. Adherence to these administrative rules is necessary for credit validity.
Mandatory Documentation and Schedules
Taxpayers claiming the QRFTC must file specific forms with their income tax return. The primary form is Schedule QR, Qualified Research Facility Tax Credit.3 This schedule is filed in the year the credit is generated and a copy must be attached to the return each subsequent year until the full credit is utilized or the 10-year carryforward period expires.3 Furthermore, a separate Schedule QR must be filed for each year that a new project qualifies.3
The most vital compliance element related to DPIS is the required supporting schedule of the tangible, depreciable property.3 This schedule must precisely list four required data points for each item of eligible property:
- Date Purchased
- Date Placed in Service
- Description
- Cost
For pass-through entities (PTEs) such as partnerships or S-Corporations, the credit flows through to the members, partners, or shareholders via the Kentucky Schedule K-1.3 These entities and owners then utilize specific forms to claim their share: corporations and other PTEs use Schedule TCS, while individuals use Schedule ITC.3
Defining DPIS for Complex Assets
While Kentucky statutes do not provide a unique definition of DPIS for the QRFTC, instructions for related state tax credits (such as Schedule RC for recycling equipment) confirm the state’s adherence to the functional readiness standard. This guidance suggests that for assets requiring installation, the DPIS should be entered as “the date the installation is completed and the equipment is ready for use”.8
This reliance on operational readiness means that for major construction or equipping projects, the DPIS date must be justifiable through operational milestones. Examples of verifiable documentation include commissioning reports, final engineering sign-offs, certificates of occupancy specifically allowing research use, or internal memoranda confirming the equipment’s readiness to run its first batch of research tests. Simply receiving the equipment or making the final payment is insufficient to establish the DPIS.
Audit Readiness: Maintaining Detailed Property Records
Given that the DOR uses the supporting property schedule to evaluate eligibility, timing, and compliance with the replacement property exclusion, detailed record-keeping is imperative.1 Taxpayers are advised to maintain detailed property records (including the date purchased, date placed in service, description, and cost) and copies of all filed Schedules QR, ITC, and TCS for at least the Kentucky statute of limitations period, typically four to five years, or longer as guided by a tax advisor.1 This detailed documentation provides the primary defense against DOR challenges regarding the year in which the credit was generated or the eligibility of the costs claimed.
Case Study Example: Timing and Application of QRFTC
This case study demonstrates the practical impact of DPIS timing on credit generation and utilization for a corporate taxpayer with a multi-year project.
Scenario Setup: Bluegrass Innovations Corp.
Bluegrass Innovations Corp. (BIC) is a calendar-year corporation expanding its Kentucky research facility. The expansion project involves $1.5 million in qualified capital costs for tangible, depreciable property supporting qualified research. BIC projects sufficient Income Tax and LLET liability to utilize the full credit over time.
Financial Breakdown and Timing Analysis (Phased DPIS)
BIC’s project spans late 2024 and mid-2025, resulting in distinct credit generation years based strictly on the DPIS of each component.
Table Title: Bluegrass Innovations Corp. QRFTC Generation Schedule
| Asset/Phase Description | Date Purchased | Date Placed in Service (DPIS) | Qualified Cost | 5% Credit Generated | Tax Year Available |
| HVAC & Utility Infrastructure (Phase 1) | 09/01/2024 | 12/20/2024 | $500,000 | $25,000 | 2024 |
| Advanced Testing Equipment (Phase 2) | 11/15/2024 | 01/10/2025 | $700,000 | $35,000 | 2025 |
| Custom Lab Benches & Fixtures (Phase 3) | 03/01/2025 | 06/30/2025 | $300,000 | $15,000 | 2025 |
| Project Totals | N/A | N/A | $1,500,000 | $75,000 | N/A |
2024 Tax Year: Only Phase 1 was placed in service before year-end (12/20/2024). This phase generates a $25,000 credit (5% of $500,000). BIC claims this credit on its 2024 Kentucky corporate return and files Schedule QR. The 10-year carryforward period for this $25,000 credit pool begins in 2024.
2025 Tax Year: Phases 2 and 3, although purchased partially in 2024, were placed in service in 2025. These phases generate a combined $50,000 credit ($35,000 + $15,000). BIC files a new Schedule QR (or a separate schedule if applicable) to reflect this new generation pool and claims the $50,000 credit against its 2025 tax liability. The 10-year carryforward period for this $50,000 credit pool begins in 2025.
Credit Utilization Model and LLET/Income Tax Allocation
Since the credit must be applied separately against LLET and Income Tax, BIC must manage two utilization streams for each generated credit pool.
2024 Utilization ($25,000 Credit Pool):
Assume BIC’s 2024 LLET liability is $10,000 and 2024 Income Tax liability is $20,000.
- BIC applies $9,825 against the LLET, reducing the liability to the minimum required $175.1
- The remaining credit balance of $15,175 ($25,000 – $9,825) is applied against the Income Tax liability.
- Result: The entire $25,000 credit generated in 2024 is utilized in the first year.
2025 Utilization ($50,000 Credit Pool):
Assume BIC’s 2025 LLET liability is $35,000 and 2025 Income Tax liability is $100,000.
- BIC applies $34,825 against the LLET, reducing the liability to the minimum required $175.
- The remaining credit balance of $15,175 ($50,000 – $34,825) is applied against the Income Tax liability.
- Result: The entire $50,000 credit generated in 2025 is utilized in the first year.
This example highlights that even if utilization occurs quickly, the DPIS date remains the legal marker for when the credit was generated and the starting point for the 10-year expiration calculation.
Strategic Considerations for Maximizing the Credit
Effective tax planning for the QRFTC centers entirely on controlling and meticulously documenting the DPIS date.
Planning DPIS: Controlling the Tax Year Boundary
Coordination between engineering, procurement, and the tax department is crucial, especially toward the end of the tax year. For assets nearing completion, confirming operational readiness (DPIS) before December 31 allows the taxpayer to secure the 5% Kentucky credit one year earlier. This acceleration provides immediate tax relief and, as noted earlier, often secures the highest possible federal bonus depreciation rate before federal phase-downs reduce the cost recovery benefit.6
A delay in confirming functional readiness from December to January results in a significant double loss: the postponement of the Kentucky credit by a full year and a reduction in the federal tax benefit. Therefore, strategic efforts to commission and place property in service before the fiscal year boundary are highly valued.
The DPIS Data Integrity Mandate
The DOR’s mandate to list the DPIS for each component in the supporting schedule means that generalized completion dates for an entire facility are inadequate.3 Taxpayers must ensure they capture granular, engineering-level data. Documentation should not rely on the date of the final payment, but rather on objective proof that the asset is functionally capable of performing qualified research.
Furthermore, property accounting systems must ensure perfect alignment between the DPIS date recorded for Kentucky Schedule QR purposes and the date used for federal depreciation reporting on Form 4562. Any misalignment between the state and federal DPIS dates creates discrepancies that can trigger scrutiny during a combined federal and state audit, potentially jeopardizing both the depreciation deduction and the tax credit claim. Maintaining a consistent, verifiable DPIS standard across all jurisdictions is a fundamental requirement of audit readiness.
Conclusion
The Date Placed in Service (DPIS) is the definitive temporal marker for the Kentucky Qualified Research Facility Tax Credit. It functions as the non-negotiable trigger for credit generation, defines the precise tax year of the claim, and initiates the strict 10-year utilization carryforward period. For multi-phased projects, each DPIS event generates a legally distinct credit pool, demanding complex tracking to manage separate application against Income Tax and the Limited Liability Entity Tax (LLET).
To fully realize the synergistic benefits of the 5% Kentucky credit alongside federal accelerated depreciation, taxpayers must adopt a proactive, functional approach to determining DPIS, moving beyond simple invoice dates to verify operational readiness. Meticulous adherence to the Kentucky DOR’s stringent documentation requirements—specifically the supporting schedule listing DPIS, purchase date, description, and cost—is paramount for mitigating audit risk and ensuring the optimal utilization of this crucial research incentive.
What is the R&D Tax Credit?
The Research & Experimentation Tax Credit (or R&D Tax Credit), is a general business tax credit under Internal Revenue Code section 41 for companies that incur research and development (R&D) costs in the United States. The credits are a tax incentive for performing qualified research in the United States, resulting in a credit to a tax return. For the first three years of R&D claims, 6% of the total qualified research expenses (QRE) form the gross credit. In the 4th year of claims and beyond, a base amount is calculated, and an adjusted expense line is multiplied times 14%. Click here to learn more.
