Analysis of Louisiana Qualified Research Expenditure (LQRE) and the R&D Tax Credit Framework

I. Executive Summary: Defining Louisiana Qualified Research Expenditure (LQRE)

A. The Two-Line Definition

Louisiana Qualified Research Expenditure (LQRE) refers to the wages, supplies, and contract costs incurred by a taxpayer for research activities strictly performed within the state of Louisiana.

These expenditures serve as the basis for calculating a fully refundable tax credit, which is tiered to provide maximum incentives (up to 30%) for small businesses focused on innovation.1

B. Contextualizing the R&D Tax Credit in Louisiana’s Economic Strategy

The Louisiana Research and Development (R&D) Tax Credit, codified under La. R.S. 47:6015, is a principal economic development tool designed to foster innovation and technological advancement within the state.3 The program’s fundamental purpose is to encourage existing businesses with operating facilities in Louisiana to either establish or continue robust research and development activities locally.2 By providing this incentive, the state aims to enhance its competitive posture against other jurisdictions.

A key strategic advantage of the Louisiana R&D credit is its structure as a fully refundable tax credit.1 Unlike non-refundable credits, which can only offset state tax liabilities and may result in an expiration of unused value, the refundable nature of the Louisiana credit means that if the credit amount exceeds the taxpayer’s liability, the state pays the difference as a cash refund. This direct cash flow benefit is particularly attractive to early-stage or high-growth companies that may not yet have significant taxable income, maximizing the program’s utility as a growth accelerator.

The state monitors the effectiveness of this investment rigorously. The Louisiana Department of Revenue (LDR) is statutorily required to perform comprehensive Return on Investment (ROI) analyses for all tax incentives where the revenue loss exceeds $1 million.4 The R&D program has demonstrated a measurable positive fiscal return, with an economic ROI reported at 29.28% in Fiscal Year 2022.5 This established history of accountability, where the program’s continuation is tied directly to its perceived economic success metrics, assures that the legislative support for the R&D credit is grounded in quantifiable performance. Consequently, the meticulous compliance requirements imposed by the Louisiana Economic Development (LED) and LDR are structured not merely for tax revenue protection, but also to ensure program integrity and validation—verifying that subsidized activities genuinely contribute to Louisiana’s documented economic growth.

II. Legal and Regulatory Framework: Alignment and Divergence from Federal Law

A. Federal Foundation vs. Louisiana Mandates

The legal definition of qualified research expenditures in Louisiana is substantially rooted in federal tax law, specifically leveraging the framework established by the Internal Revenue Code (IRC). The Louisiana Revised Statutes explicitly mandate that the terms “Qualified Research Expenses” and “Qualified Research” possess the same meanings as defined in 26 U.S.C. 41 (the Federal R&D Tax Credit statute), as amended.6 This ensures that activities must satisfy the rigorous four-part test recognized at the federal level: the activity must be technological in nature, designed to eliminate uncertainty, involve a process of experimentation, and be undertaken for a permitted purpose, typically related to developing new or improved products, processes, or software.7

Despite this foundational alignment with federal definitions, the state imposes one critical mandate that governs the entire application of LQRE: all qualified research expenditures must be incurred in Louisiana.1 Only research and development conducted within the state’s geographic boundaries will qualify for the tax credit incentive.2 This strict geographic requirement is central to ensuring that the refundable credit supports economic activity and job creation exclusively within Louisiana. Furthermore, to be eligible for certification, the taxpayer must claim the expenditures within a specific timeframe—no later than one year after December 31 of the calendar year in which the expenditure was incurred.2

B. Statutory Exclusions and Innovation Focus

Louisiana’s statute incorporates specific filters designed to direct the incentive toward genuine, high-level technological innovation, rather than routine service provision or customized fabrication. The law explicitly restricts participation in the R&D program for two distinct categories of businesses unless they satisfy an additional, stringent intellectual property (IP) requirement 1:

  1. Professional services firms.
  2. Businesses primarily engaged in custom manufacturing and custom fabricating.

For these entities, eligibility requires that they possess a pending or issued United States patent related to the qualified research expenditures being claimed.1 This legislative requirement serves as a powerful statutory filter. It effectively mandates that for these specific types of firms—which often conduct internal research related to client work or highly customized outputs—the subsidized research must result in protectable intellectual property recognized by the U.S. Patent Office.

This requirement elevates the evidentiary standard significantly. It prevents the credit from subsidizing routine consulting, administrative process improvements, or non-technological customization activities. Instead, it ties state financial incentives directly to the creation of verifiable, high-value IP within Louisiana. Therefore, for professional services or custom fabrication businesses operating in Louisiana, their R&D financial strategy must be intricately linked with their IP portfolio management to secure the tax credit benefits.

III. Exhaustive Analysis of Qualified Research Expenditures (LQRE)

The determination of LQRE is strictly limited to three expenditure categories: wages, supplies, and contract research costs. Each category is defined by specific rules governing the direct nature of the research activity and unique Louisiana-specific limitations.8

3.1. Qualified Wages: The Direct Link Requirement

Qualified wages represent compensation paid or incurred by the taxpayer for services that directly relate to the research activities.8 This category includes all remuneration (subject to income tax withholding) paid to an employee for performing qualified services.

The statute defines qualified services functionally, necessitating that the employee’s role fits one of three direct research functions 8:

  1. Direct performance of qualified research (e.g., the scientist running the experiment).
  2. Direct supervision of qualified research (e.g., the team leader managing the technical execution).
  3. Direct support of qualified research (e.g., a technician preparing samples or maintaining the research equipment).

Crucially, the regulation explicitly excludes General or Administrative (G&A) wages.8 Costs considered indirect or incidental to the research activity are ineligible. A common example provided in state guidance illustrates this point: an allocated portion of wages for personnel in the purchasing or receiving department generally does not qualify, as their duties represent indirect support rather than direct engagement with the research.8

For businesses seeking to claim this component of LQRE, the clear segregation of qualified services from non-qualified services is paramount. This necessitates the implementation of robust internal tracking systems—such as detailed time-tracking procedures—to accurately document the percentage of employee time spent strictly on direct R&D functions versus non-qualifying administrative or indirect support tasks. The integrity of the credit claim rests entirely on the ability to substantiate the direct link between the wages paid and the eligible research activity performed within the state.

3.2. Qualified Supplies: Consumption and Depreciation Rules

Qualified supplies include tangible property that is consumed directly by the research activity or that is utilized in the development of a prototype.8 The supplies must be integral to the conduct of the qualified research activity itself.8

Louisiana law strictly adheres to exclusions for capital expenditures and indirect operational costs, which mirror, and sometimes clarify, federal rules 8:

  1. Capital Assets: Supplies do not include land, improvements to land, or any property subject to the allowance for depreciation.8 This means equipment or facilities with a useful life extending beyond the research project are ineligible for the supply credit.
  2. Operational Overhead: Specific operational items are explicitly excluded, emphasizing that the credit targets material inputs consumed in the experiment, not general infrastructure. Non-qualifying costs include utilities (such as phone and electricity), small tools, and allocations of total shipping cost.2

This exclusion of utilities and small tools ensures that the credit is focused on the core material inputs that are fundamentally necessary and consumed during the experimentation process (ee.g., raw chemicals in a laboratory, or components used in a destructively tested prototype). General support costs required to keep the research facility operational are treated as overhead and are not eligible for inclusion in LQRE.

3.3. Contract Research Expenses (CRE): The 65% In-State Limitation

Contract research expenses cover amounts paid to non-employees, such as outside consultants, to perform qualified research.8 This is the most complex category of LQRE and presents the greatest divergence from typical federal R&D tax credit provisions.

To qualify contract research, two contractual prerequisites must be established 2:

  1. Written Agreement: The taxpayer must enter into a formal, written agreement with the contractor prior to the commencement of the research.
  2. Financial Risk: The taxpayer must be contractually required to bear the costs of the research, even if the research ultimately proves unsuccessful. This demonstrates that the taxpayer is the true beneficiary and financial risk-taker of the R&D activity.

Beyond these federal-style requirements, Louisiana imposes a strict geographic and cost reduction mandate that significantly alters the financial value of outsourced R&D 2:

  • In-State Mandate: The consultant must perform the research within Louisiana.8 If a contract involves research conducted both within and outside the state, only the expenditures incurred within Louisiana are potentially eligible for inclusion.8
  • The 65% Limitation: Even after satisfying the in-state requirement, only 65% of the qualified Louisiana contract research expense qualifies for the credit calculation.2 The remaining 35% is statutorily disallowed from the credit base.

This structural reduction represents a deliberate policy decision by the state to prioritize the internalization of R&D activity. A dollar spent on qualified services performed by a W-2 employee (wages) is fully included (100%) in the LQRE base, maximizing the potential credit. Conversely, a dollar spent on an equivalent external contractor is only 65% included. This effective cost discrepancy functions as a strong incentive, encouraging businesses to directly hire and retain in-state R&D staff, thereby reinforcing the program’s primary economic development goal of job creation within Louisiana.3 The maximum credit benefit on outsourced R&D is thus capped at 19.5% (30% maximum rate multiplied by 65% inclusion rate).

IV. Calculating the Louisiana R&D Credit: The Tiered System Methodology

The calculation of the Louisiana R&D credit is based on the increase in current-year LQRE over a calculated historical “base amount.” The system is strategically tiered according to employee headcount, resulting in vastly different calculation methodologies and final credit percentages across company sizes.

4.1. Identifying the Employee Tier

The number of persons employed by the entity determines the specific calculation hurdle and the applicable credit rate.1 The term “person” generally refers to a natural person.6

4.2. Establishing the Base Amount (The Hurdle)

The base amount serves as the minimum level of R&D spending a company must exceed in the current year to generate an incremental credit. It is calculated using the average LQRE incurred during the three preceding taxable years.6 The percentage applied to this average is highly dependent on the employee tier:

  • Small Business Advantage (<50 Persons): Taxpayers who employ less than fifty persons calculate their base amount as 50% of the average annual LQRE incurred within Louisiana during the three preceding taxable years.6 This lower base threshold makes it significantly easier for small companies to demonstrate growth in R&D investment and, consequently, to earn a credit.
  • Larger Entity Hurdle (50+ Persons): For taxpayers employing fifty or more persons, the base amount is calculated as 80% of the average annual LQRE over the three preceding years.6 This higher hurdle necessitates a much greater year-over-year increase in current R&D spending to produce a comparable credit amount relative to the smaller tier.

4.3. Applying the Tiered Credit Rate

The final credit amount is derived by taking the difference between the current year’s total LQRE and the calculated base amount, and multiplying this difference by the applicable tiered credit rate.1

  • Small Business Tier (<50 Employees): Entities in this tier receive the maximum rate of 30%.1
  • Mid-Sized Tier (50–99 Employees): Companies falling into this category receive a 10% credit rate.1
  • Large Business Tier (100+ Employees): The largest companies receive a 5% credit rate.1

The statutory design embeds a significant discontinuity—a “growth cliff”—at the 50-employee threshold. If a company approaches this boundary, hiring an additional employee to cross the 50-person line results in a dual penalty: the base amount hurdle increases from 50% to 80% of historical spending, and the credit rate plummets from 30% to 10%. This abrupt reduction mandates detailed, forward-looking strategic workforce planning. Businesses must carefully evaluate whether the economic value derived from the 50th employee offsets the immediate and substantial reduction in the refundable tax credit benefit. This strategic dynamic compels companies to manage their staffing levels consciously to maximize the program’s intended incentive effect.

The tiered calculation structure is summarized below:

Louisiana R&D Credit Tiered Calculation Structure (La. R.S. 47:6015)

Employee Headcount Base Amount Calculation Credit Percentage (Tiered Rate)
Less than 50 50% of Avg. LQREs over 3 preceding years 30% of (Current LQRE – Base Amount)
50 to 99 80% of Avg. LQREs over 3 preceding years 10% of (Current LQRE – Base Amount)
100 or more 80% of Avg. LQREs over 3 preceding years 5% of (Current LQRE – Base Amount)

V. State Revenue Office Guidance and Compliance Requirements

Claiming the Louisiana R&D tax credit is a mandatory two-step administrative process involving distinct responsibilities for two state agencies: the Louisiana Department of Economic Development (LED) and the Louisiana Department of Revenue (LDR). Certification must be obtained from LED before any credit can be filed or amended with LDR.2

5.1. The Role of Louisiana Economic Development (LED): Certification and Verification

The first critical step involves obtaining credit certification from the Department of Economic Development (LED). Taxpayers are statutorily required to apply to LED for the credits authorized in La. R.S. 47:6015.6 This pre-certification process serves as a rigorous vetting mechanism to confirm that the activities meet the definition of qualified research and that the expenditures claimed were properly incurred in Louisiana.

LED imposes strict procedural and financial requirements:

Application and Documentation: An application, typically requiring a small standard fee (e.g., $250), must be completed online or submitted by mail, along with specific required documentation.2 This documentation must include, where applicable, the filed Federal Form 6765 for the current tax year and the three previous tax years, along with a detailed listing of the Louisiana-only qualified research expenses for the base years.2 Taxpayers seeking the Small Business Innovation Research (SBIR/STTR) credits must also provide copies of the grants and a listing of disbursements received.2

The One-Year Rule: The application process is time-sensitive. Taxpayers must ensure the expenditures are claimed within one year after December 31 of the year in which the expenditure was incurred.2 For example, if qualified expenses were incurred during a fiscal year ending June 30, 2015, the application deadline for certification would be no later than December 31, 2016.10

Expenditure Verification Report (EVR): To maintain the integrity of the claims, the state requires the taxpayer to fund an Expenditure Verification Report (EVR). This report is conducted by an independent certified public accountant (CPA) or tax attorney selected by LED, which requires the taxpayer to make all relevant records available.11 A substantial deposit is required at the time of application to cover the cost of this verification process.6

The requirement for a mandatory, significant deposit ensures that the administrative burden and cost of rigorous verification are substantially borne by the taxpayer. This financial barrier effectively filters out marginal or less-confident claims, ensuring that the state’s audit and verification resources are focused efficiently on claims that have already demonstrated financial viability relative to the verification costs.

LED Application and Expenditure Verification Fees

LQRE Claimed in Application Required Deposit for EVR
Up to $1,000,000 $7,500
In Excess of $1,000,000 $15,000
Base Application Fee (Standard) $250

5.2. The Role of Louisiana Department of Revenue (LDR): Claim and Refund

Once LED certifies the credit amount, the taxpayer is notified, and the Louisiana Department of Revenue (LDR) is informed.2 The taxpayer then proceeds to file or amend their state income tax return to claim the certified tax credits.2 The R&D credit reduces either income tax or corporation franchise tax.10

Since the credit is generally fully refundable, LDR issues a cash refund once all outstanding state liabilities of the taxpayer have been resolved.10 If, in rare cases, the credit is not used in the current year, it can be carried forward for a period not to exceed five years.1

Furthermore, while the primary R&D credit is non-transferable, additional credits received for federal SBIR or SBTT grants may be transferred or sold to another Louisiana taxpayer.1 If such a transfer occurs, the applicant must notify LDR within 10 business days of the transaction, and the transfer must be completed by the original due date of the return.10 LDR issues Form R-6135 for tracking the utilization of these credits.10

VI. Statutory Limitations and Strategic Considerations

6.1. The Upcoming $12 Million Annual Cap (Act 11)

A critical future consideration for all R&D claimants is the implementation of an annual funding cap, established by Act 11. Historically, the R&D credit has been uncapped.2 However, effective for claims allowed on returns filed on or after July 1, 2025, the aggregate amount of the R&D tax credit allowed across all taxpayers in each fiscal year will be strictly limited to $12 million.1

This statutory change fundamentally alters the strategic risk profile of the credit. The uncapped refundability advantage, which previously guaranteed the credit upon qualification, is being transformed into a potentially limited, time-sensitive resource.

Allocation and Priority: Claims are explicitly handled on a first-come, first-served basis.1 Act 11 also explicitly prohibits the rollover of any unused portion of the cap from one credit cap year to the next; any unused capacity is simply forfeited.12

Mitigation Strategy: The legislation provides a mechanism for taxpayers whose R&D credit claims are disallowed in one fiscal year due to the $12 million cap having been exhausted. These taxpayers are allowed to use the disallowed credits on an original return filed in the subsequent fiscal year. Crucially, their resubmitted claims will receive priority over all other claims filed after the original return date.1

The introduction of the cap necessitates a shift in tax strategy, especially for large entities claiming significant credit amounts. The focus is no longer solely on technical qualification but on the timely completion of certification and filing. To secure a portion of the limited $12 million pool, large R&D performers must ensure LED certification is obtained well in advance of the fiscal year start (July 1st). They must be prepared to file their final tax returns—or potentially amended returns, if necessary—immediately upon or shortly after the July 1st cap year commencement to ensure their claim is processed and allowed before the annual pool is exhausted. This dynamic elevates tax compliance to a time-critical strategic race for funds.

VII. Illustrative Example: Application Across Different Tiers

To demonstrate the profound effect of the tiered system on the ultimate credit value, the following scenario compares three hypothetical companies that achieve the same absolute growth in LQRE but differ only in their employee headcount.

Scenario Details

Assume all three companies (Alpha, Beta, and Gamma) have a consistent history of R&D spending, resulting in an average LQRE of $100,000 over the three preceding tax years (Base Period Avg. QRE = $100,000). In the current tax year, all three companies incur $200,000 in new, certified LQRE, representing a 100% increase in spending.

The comparison highlights how the statutory differences in Base Calculation Rate and Credit Rate heavily influence the final refundable credit amount.

Tiered Calculation Comparison Example

Metric Alpha Tech (40 Employees) Beta Systems (75 Employees) Gamma Corp (150 Employees)
Tier Small Business (<50) Mid-Sized (50-99) Large Business (100+)
Current Year LQRE $200,000 $200,000 $200,000
Base Period Avg. QRE $100,000 $100,000 $100,000
Base Calculation Rate 50% 6 80% 6 80% 6
Calculated Base Amount $50,000 $80,000 $80,000
Increase Over Base $150,000 $120,000 $120,000
Credit Rate 30% 7 10% 7 5% 7
Calculated R&D Credit $45,000 $12,000 $6,000

Conclusion of Example

Despite all three companies achieving the exact same $100,000 growth in Louisiana Qualified Research Expenditure, the outcomes are vastly different. Alpha Tech, the small business, receives a refundable tax credit of $45,000. This is 3.75 times the credit received by Beta Systems ($12,000) and 7.5 times the credit received by Gamma Corp ($6,000).

This dramatic variance is a direct result of Louisiana’s statutory policy of prioritizing small business innovation. The lower base calculation rate (50% versus 80%) maximizes the “Increase Over Base” amount, and the significantly higher credit rate (30% versus 5% or 10%) maximizes the final credit value. This example underscores the importance of employee headcount management as a financial optimization strategy under the Louisiana R&D incentive program.

VIII. Conclusion: Strategic Policy and Compliance Mandates

The Louisiana Qualified Research Expenditure (LQRE) framework is a highly structured and financially potent state tax incentive program, designed to stimulate in-state innovation. It achieves this by mirroring the technical rigor of the federal R&D tax credit while layering in unique policy mechanisms tailored to state economic goals, such as maximizing the benefit for small enterprises and encouraging direct job creation.

The comprehensive definition of LQRE is restricted exclusively to wages, supplies, and contract research performed in Louisiana. Critical compliance demands stem from three key areas: first, the meticulous segregation of direct qualified services from non-qualifying G&A costs; second, adherence to the 65% limitation for contract research, which strongly signals a preference for internalized R&D talent; and third, the specific IP requirement for custom manufacturing and professional services firms, which ensures that subsidies are tied to the creation of high-value, patentable intellectual property.

The process is administratively rigid, requiring mandatory pre-certification by LED before LDR can process the refundable claim. The financial requirement for a substantial Expenditure Verification Report deposit reinforces the state’s focus on claim integrity and places the administrative cost of verification directly upon the claimant.

Furthermore, the introduction of the $12 million annual cap, effective July 1, 2025, fundamentally shifts the strategic landscape for all claimants. The historically predictable, uncapped refundable credit transforms into a finite resource pool allocated on a time-critical, first-come, first-served basis. Taxpayers must now integrate the R&D credit into their critical financial path, ensuring the rapid completion of LED certification and the early filing of tax returns to secure their certified credit against the annual ceiling.

To navigate the administrative complexities, the tiered calculation hurdles, the strategic “growth cliffs” (e.g., at 50 employees), and the evolving statutory limitations, specialized tax policy consultation is highly recommended. The Louisiana R&D credit offers significant cash flow advantages, but realizing that benefit requires treating the process as a sophisticated, multi-step compliance and strategic timing function.

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.
