Navigating Basic Research Payments (BRPs) and the Hawaii R&D Tax Credit (HRS §235-110.91)

I. Executive Summary: The Strategic Value of Basic Research Payments in Hawaii

A. The Two-Line Meaning and Context

Basic Research Payments (BRPs) are defined as cash expenditures made by a corporation to qualified research organizations, such as universities, for fundamental scientific inquiry under a documented written agreement.1 These payments are fully recognized as Qualified Research Expenses (QREs) and constitute a high-value component of the refundable Hawaii Tax Credit for Research Activities (TCRA) under HRS §235-110.91.2

B. Strategic Overview and the Act 139 Imperative

The Hawaii TCRA, codified under Hawaii Revised Statutes (HRS) §235-110.91, serves as a crucial, refundable state incentive designed to stimulate innovation, particularly among certified Qualified High Technology Businesses (QHTBs) focused on high-tech sectors like biotechnology and software development.3 The credit provides immediate cash recovery against research costs because unused portions are refunded directly to the taxpayer, a mechanism highly valuable for funding high-risk, long-cycle scientific investigation, which often characterizes basic research. This refundability converts speculative investments into guaranteed cash flow benefits, thereby promoting early-stage economic stimulus within the state.

The structure of the credit is constrained by two major limitations: an expiration date of December 31, 2029, and a strict statewide annual aggregate cap of $5 million allocated on a first-come, first-served basis via certification.4

The regulatory environment underwent a fundamental shift with the passage of Act 139 of 2024. This legislation reinstated the federal incremental base calculation requirement under Internal Revenue Code (IRC) §41.3 Previously, Hawaii often allowed credits on all qualified expenses without regard to prior years’ spending. The new rules mean that the credit is now only available for QREs that exceed a historical four-year spending average, forcing QHTBs to increase their current research expenditure to realize a tax benefit.3 This reinstatement means that the state credit now explicitly rewards growth in research expenditure rather than simply subsidizing all research activity, increasing the need for precise planning and sophisticated compliance when utilizing BRPs.

II. The Federal Statute: Defining Basic Research Payments (BRP)

A. Statutory Mandate: IRC Section 41(e) Detailed Analysis

The Hawaii TCRA explicitly aligns with the federal framework provided by IRC §41 for defining eligible research activities and expenditures.3 Basic Research Payments, specifically addressed in IRC §41(e)(2)(A), must satisfy several strict federal requirements to qualify for inclusion in the credit base:

1. Payer and Form: The payment must originate from a corporation and must be paid strictly in cash during the taxable year.1 Non-cash contributions, such as donations of intellectual property or equipment, are ineligible as BRPs. Although the payment must originate from a corporation, the resulting calculated credit benefit can be distributed and claimed by partners or shareholders if the QHTB operates as a flow-through entity (S-corporation, partnership, or LLC).3
2. Purpose: The expenditure must be designated for “basic research,” which IRC §41 defines as any original scientific investigation for the advancement of scientific knowledge that does not have a specific commercial objective.1
3. Documentation: Crucially, the payment must be made pursuant to a written agreement between the corporation and the qualified organization.1 This document must establish the terms of the research and is mandatory for state compliance certification.

B. Defining a “Qualified Organization”

For a payment to qualify as a BRP, the recipient organization must meet specific federal criteria established under IRC §41(e). Generally, qualified organizations include institutions of higher education (such as the University of Hawaii system) and certain tax-exempt organizations established primarily for scientific research.1 Verifying the recipient’s qualified status is a prerequisite for including the BRP in the calculation.

C. Distinguishing BRPs from Contract Research Expenses

BRPs are treated more favorably than other forms of contract research expenditures under IRC §41, providing a significant financial incentive for QHTBs to partner with academic institutions.

Payments made for standard contract research (outsourced specific product or process development) are generally included as Qualified Research Expenses (QREs) at a rate of only 65% of the payment amount.7 In contrast, BRPs are recognized at 100% of the cash paid.1 This differential inclusion rate means that BRPs generate approximately 53.8% more QRE value per dollar spent compared to standard contract research.

This 100% inclusion rate offers a major financial opportunity. Taxpayers must ensure the terms of the written agreement and the nature of the activities strictly adhere to the definition of “basic research.” If the activity is deemed too closely tied to specific commercial objectives or product development, the payment could be reclassified as standard contract research, leading to a substantial reduction in the QRE base and a corresponding decrease in the Hawaii refundable credit.

III. Hawaii’s R&D Credit Framework: HRS §235-110.91

A. QHTB Eligibility and Scope

The eligibility for the Hawaii TCRA is strictly limited to certified Qualified High Technology Businesses (QHTBs).3 These entities must satisfy three critical state requirements:

1. Geographic Nexus: The business must conduct more than 50% of its qualified research activities within the State of Hawaii.4
2. Registration: The business must be registered to do business within the State of Hawaii.4
3. Small Business Mandate: As instituted by Act 139 in 2024, the definition of QHTB was narrowed to businesses classified as a small business, meaning a company with no more than 500 employees.4

B. Statutory Conformity: The Act 139 Base Reinstatement (2024)

Historically, Hawaii’s implementation of the R&D credit often permitted taxpayers to claim a credit on all qualified in-state expenses without requiring the reduction imposed by the federal incremental base amount. Act 139, Session Laws of Hawaii 2024, specifically repealed this provision for tax years beginning after December 31, 2023.6

The updated rules explicitly state that the base amount calculation in IRC §41 will now apply, and credits for all qualified research expenses may not be taken without regard to the amount of expenses for previous years.3

This reinstatement fundamentally alters the strategic planning for the credit. By adopting the federal incremental calculation, Hawaii has focused the credit mechanism on rewarding increased research spending over time. Established QHTBs that maintain consistent BRPs and other QRE levels—even substantial amounts—may find their credit significantly diminished or entirely eliminated if their current-year QREs do not exceed their historical four-year average (the base amount). This creates a critical budgeting and forecasting requirement for QHTBs aiming to leverage BRPs or other research expenditures to qualify for the refundable credit.

IV. Local State Revenue Office Guidance and Calculation Methodology

Hawaii’s Department of Taxation (DOTAX) and the Department of Business, Economic Development, and Tourism (DBEDT) require taxpayers to utilize the results of the federal credit calculation, Form 6765, and then apply a specific ratio to determine the Hawaii-specific refundable credit amount.

A. The Role of BRPs in the Incremental Calculation

BRPs are fully included in the total Current Year Qualified Research Expenses (QREs) used to calculate the federal credit under IRC §41. This inclusion impacts the calculation in two primary ways:

1. Base Calculation: The base amount is calculated as the Fixed-Base Percentage (historically derived from a company’s research intensity during a specific base period, often 6.0% for established firms) multiplied by the average annual gross receipts of the four preceding tax years.3
2. Minimum Base Test: IRC §41 mandates that the calculated base amount must be at least 50% of the Current Year QREs.8 Because BRPs are recognized at 100% of their cost, a large BRP expenditure can substantially inflate the total Current Year QREs, potentially raising the mandatory minimum base amount. This means that large BRP investments, while fully includible, must be carefully considered against the historical spending patterns to ensure they result in an incremental amount that clears the minimum base threshold and generates a credit.

B. Calculating the Hawaii Credit (The Pro-Rata Formula)

The Hawaii TCRA calculation (post-Act 139) is a three-step process that localizes the federal incremental credit 3:

Step 1: Calculate the Total Federal Credit

The QHTB must first calculate the Federal R&D Credit amount using IRS Form 6765, which incorporates the incremental base calculated in Section IV.A.

$$\text{Federal Credit} = \text{Applicable Percentage} \times (\text{Total Federal QREs} – \text{Federal Base Amount})$$

Step 2: Determine the Hawaii Expense Ratio

This ratio ensures that the credit is limited to the proportion of research activity conducted within the state.

$$\text{Hawaii Expense Ratio} = \frac{\text{Hawaii QREs (including HI BRPs)}}{\text{Total Federal QREs (including all BRPs)}}$$

It is critical that QHTBs localize their BRP activity. The Hawaii Department of Taxation (DOTAX) Form N-346, used to claim the credit, features a line specifically for reporting “Basic research payments to qualified organizations” conducted IN HAWAII (Line 1b).2 To be included in the numerator of the ratio, the research activity funded by the BRP must be demonstrably located in Hawaii. For multi-state taxpayers, if a BRP is paid to an organization outside Hawaii, it increases the denominator (Total Federal QREs) but not the numerator (Hawaii QREs). This result dilutes the Hawaii Expense Ratio, thereby reducing the final refundable Hawaii credit. Therefore, maximizing the local credit requires prioritizing partnerships with Hawaii-based qualified organizations for basic research funding.

Step 3: Final Credit Determination

The final refundable Hawaii credit amount is calculated by scaling the federal incremental credit by the Hawaii Expense Ratio.

$$\text{Hawaii Refundable TCRA} = \text{Federal Credit} \times \text{Hawaii Expense Ratio}$$

V. Operationalizing BRPs in Hawaii Compliance

A. DBEDT Certification: Form N-346A

Compliance for the Hawaii TCRA operates under a dual-agency system involving DBEDT and DOTAX. Certification by DBEDT is a mandatory prerequisite for claiming the credit.3

QHTBs must submit Form N-346A (Certified Statement of Research and Development Costs) and a detailed questionnaire to DBEDT during a specific annual application window (e.g., March 3–31 of the following year).3 Due to the $5 million annual cap, which is allocated on a first-come, first-served basis, timely submission is paramount.4 Upon review and acceptance, DBEDT approves and signs Part II of Form N-346A, which constitutes the official certificate verifying the amount of credit that may be claimed.6

B. DOTAX Filing and Reporting: Form N-346

The credit is formally claimed by attaching the DBEDT certificate (Part II of N-346A) to the taxpayer’s Hawaii income tax return, utilizing DOTAX Form N-346 (Tax Credit for Research Activities).3

Form N-346 requires specific reporting of the research expenses incurred in Hawaii. QHTBs must report Hawaii-based Basic Research Payments to qualified organizations on Line 1b of Form N-346.2 For flow-through entities, the QHTB is responsible for distributing copies of the DBEDT certificate and Schedule K-1 (showing the allocated credit) to its partners, shareholders, or beneficiaries, who must then attach both documents to their individual Hawaii tax returns.3

C. Audit Authority and Documentation

Although DBEDT is responsible for initial certification and managing the credit cap, the Director of Taxation maintains statutory authority to audit and adjust the final claimed tax credit amount, ensuring conformity to the facts of the case.5 This bifurcation of authority means that the DBEDT certificate is a necessary step, but it does not guarantee the final credit amount.

QHTBs must be prepared for potential DOTAX audits by maintaining meticulous documentation for all BRPs. This documentation must include:

• The original written agreement outlining the basic research objective.1
• Proof that the payment was made in cash.
• Verification of the recipient’s qualified organization status.

A failure to maintain audit-ready documentation for the BRPs, or deficiencies in applying the complex new incremental calculation under Act 139, could lead to a disallowance or adjustment by DOTAX, even if the QHTB received initial certification from DBEDT.

VI. Detailed Case Study: Application of BRPs under Hawaii Law (Post-Act 139)

This example demonstrates the calculation of the Hawaii TCRA, incorporating a Basic Research Payment (BRP) under the incremental base rules required by Act 139.

A. Scenario Setup: “Mauna Loa Biotech” (QHTB)

Mauna Loa Biotech is a certified QHTB registered in Hawaii with 350 employees (qualifying as a small business under the $\le 500$ employee rule).6 The company conducts over 50% of its research in Hawaii.

B. Calculation Step-by-Step

Step 1: Calculate the Federal Base Amount (IRC §41)

1. Fixed-Base Calculation:
   
   $$0.06 \times \$40,000,000 = \$2,400,000$$
2. Minimum Base Test: 50% of Current Year QREs
   
   $$0.50 \times \$4,500,000 = \$2,250,000$$
3. Result: The Federal Base Amount is the greater of the two: $2,400,000.

Step 2: Calculate Federal Incremental QREs and Federal Credit

1. Incremental QREs:
   
   $$\$4,500,000 \text{ (Total Federal QREs)} – \$2,400,000 \text{ (Federal Base)} = \$2,100,000$$
2. Federal Credit (20% Regular Rate):
   
   $$0.20 \times \$2,100,000 = \text{\$420,000}$$

Step 3: Calculate the Hawaii Expense Ratio

The BRP of $700,000 is included in the Hawaii QREs because it was paid to a qualified organization located in Honolulu and tied to research conducted in Hawaii.

1. Ratio:
   
   $$\frac{\$3,600,000 \text{ (Hawaii QREs)}}{\$4,500,000 \text{ (Total Federal QREs)}} = 0.80 \text{ or } 80\%$$

Step 4: Determine the Hawaii Refundable TCRA

1. Hawaii TCRA:
   
   $$\text{\$420,000} \text{ (Federal Credit)} \times 0.80 \text{ (Hawaii Expense Ratio)} = \text{\$336,000}$$

The final refundable credit claimed by Mauna Loa Biotech on Form N-346, after receiving the necessary N-346A certificate from DBEDT, is $336,000.

VII. Strategic Considerations and Conclusion

A. QRE Utilization Trends and the BRP Investment Gap

Data regarding the utilization of Qualified Research Expenses in Hawaii indicates a reliance on internal labor costs. For the 2024 tax year, certified QHTBs reported that over 80.9% of their qualified research expenses incurred in Hawaii were allocated to wages, whereas only 4.1% was attributed to “Contract research and other research payments” (the category that encompasses BRPs).9

This low allocation to external research suggests a significant opportunity cost for QHTBs. Given that BRPs are recognized at 100% of cost—a major financial advantage over other expense categories—businesses may be underutilizing this high-value avenue to expand their QRE base. Under the new rules imposed by Act 139, QHTBs must now overcome a historical spending base to realize any credit.3 By strategically increasing BRPs through partnerships with local academic and research institutions, QHTBs can efficiently boost their total QREs, increasing the likelihood of exceeding the incremental base amount and thus maximizing the eventual refundable credit benefit.

B. The Sunset Provision and Future Planning

The Hawaii Tax Credit for Research Activities, including the recognition of BRPs, is currently scheduled to be repealed from statute on December 31, 2029.4 Businesses leveraging this incentive must adopt a proactive, multi-year strategy to maximize its benefits before expiration.

The analysis confirms that successfully claiming the refundable Hawaii TCRA relies on precise execution across three key areas:

1. Strict Compliance with the Incremental Base: Due to Act 139, QHTBs must ensure that their current-year BRPs, when combined with other QREs, result in spending growth above the computed federal base amount. Budgeting must be structured to ensure this incremental expenditure is realized annually.
2. Geographic Localization: For multi-state firms, priority must be given to ensuring that BRPs are paid to Hawaii-based qualified organizations and are demonstrably linked to research activities conducted within the state. This localization is essential to maintaining a high Hawaii Expense Ratio and preventing the dilution of the final state credit.
3. Mandatory Documentation and Certification: Businesses must adhere rigidly to the annual DBEDT certification process (Form N-346A) and maintain meticulous audit documentation, particularly the written agreements and cash payment records required for BRPs, recognizing the dual audit authority held by DBEDT and DOTAX.5
