The Hawaii Tax Credit for Research Activities (HRS §235-110.91) incentivizes qualified high technology businesses (QHTBs) to invest in innovative research conducted within the state, offering a refundable credit against Hawaii income tax, certified by the Department of Business, Economic Development, and Tourism (DBEDT) and claimed with the Department of Taxation. Updated in 2024 by Act 139 (from SB 2497), the credit aligns closely with federal provisions under IRC §41, including the base amount calculation, and supports key sectors like biotechnology, software development, and ocean sciences through 2029.

How to Calculate the Hawaii R&D Tax Credit

Hawaii uses a federal-aligned method, calculating the credit as a pro-rata share of the federal R&D credit based on Hawaii-sourced QREs. Per 2024 updates (Act 139), the federal base amount under IRC §41 applies—only incremental QREs qualify. Only in-state QREs count toward the ratio

Regular Method (Federal Share)
  • Compute your total federal R&D credit using Form 6765 (regular or ASC method, including base amount).
  • Determine Hawaii QREs for the tax year (wages, supplies, etc., tied to qualified high-tech activities).
  • Calculate the ratio: Hawaii QREs ÷ Total Federal QREs.
  • Credit = Federal Credit × Ratio.
  • Obtain DBEDT certification (Form N-346A) during the annual application window; attach to Form N-346 with your tax return.
Example Calculation
Assume $2M total federal QREs, with $1.2M excess over base yielding a $240K federal credit (20% rate). Hawaii QREs =$800K (40% ratio).
→ Hawaii Credit = $240K × 40% =$96K (refundable if exceeds liability).
If using ASC federally: Base =50% of prior 3-year average QREs; apply 14% to excess, then pro-rate.
Important: Certification is first-come until $5M cap reached. No Hawaii-specific base—use federal computation. Startups may benefit from federal fixed-base rules (3% initial phase-in).
Base Calculation fo Hawaii R&D Tax Credit
  • Compute federal base amount per IRC §41: fixed-base percentage × average annual gross receipts for the 4 preceding tax years (not less than 50% of current-year QREs).
  • Use this federal base to determine federal excess QREs = current federal QREs - base.
  • Federal credit = applicable percentage (e.g., 20% regular) × excess.
  • Then, Hawaii credit = federal credit × (Hawaii QREs / federal QREs).
  • For startups, fixed-base starts at 3%.
Example Calculation
Federal average gross receipts (prior 4 yrs) = $10M; fixed-base % = 5% → Base =$500K
Current federal QREs = $1.2M → Excess = $700K → Federal credit (20%) =$140K
Hawaii QREs = $480K (40% of federal) → Hawaii credit = $140K × 40% =$56K
Gross Receipts for Federal Base (Hawaii Impact)
  • Federal gross receipts used for base; Hawaii QREs only for ratio. Exclude non-Hawaii activities. No Hawaii receipts? Federal base still applies proportionally.

Hawaii-Specific Rules

Hawaii's R&D credit emphasizes high-tech innovation with strict certification and compliance to allocate the limited cap effectively.

QHTB Certification Requirements

Businesses must register in Hawaii, limit to 500 employees, and conduct >50% of activities in qualified research. Apply March 3–31, 2025 (fee waived); DBEDT reviews Form N-346A and questionnaire for approval by ~June 30. Utilization has focused heavily on computer software and biotechnology, with tens of millions of dollars in credits awarded since 2013, but cap fills quickly—early submission critical.

First-Come, First-Served Cap

$5M annual aggregate cap drives competition; allocations prioritized by application timestamp. Once exhausted, no further certifications issued that year. No per-taxpayer limit, but individual certificates have recently ranged from a few thousand dollars to roughly 700,000 dollars, with averages in the low hundreds of thousands.

Annual Compliance Survey

All certified QHTBs file a June 30 survey detailing expenditures and credits claimed. Non-filing risks losing the credit and potential audit. Ensures program accountability for ocean sciences and astronomy sectors.

Other Rules
  • Pass-Through Treatment: Credits apply against personal income tax for owners; pro-rata allocation via K-1
  • Sunset Provision: Available through December 31, 2029; monitor for extensions.
  • Audit Guidelines: Retain records 4 years; DBEDT/Department of Taxation may request payroll/expense substantiation.

Hawaii R&D Tax Credit

Discover the benefits of Hawaii state credits and see how your business could qualify.

Hawaii's Tax Credit for Research Activities (§235-110.91) is similar to the federal R&D tax credit provided by IRC § 41, but research activities must be conducted in Hawaii.

Hawaii provides a refundable income tax credit for qualified high technology businesses (QHTBs) with Hawaii research activities subject to an annual cap of $5 million. To comply with this restriction, the Department of Business, Economic Development, and Tourism (DBEDT) shall certify credits on a first-come, first-served basis. With references to the base amount under IRC § 41 no longer applying after 2019, credit for all qualified research expenses may be taken without regard to the amount of expenses for previous years. The credit equals the federal credit claimed on Form 6765 multiplied by the ratio of expenses between Hawaii and the federal total.

Every QHTB claiming the R&D credit shall submit a written, certified statement to the department of business, economic development, and tourism identifying:

    (1)  Qualified expenditures, if any, expended in the previous taxable year; and

    (2)  The amount of tax credits claimed pursuant to this section, if any, in the previous taxable year.

The DBEDT will issue a certificate to the taxpayer after reviewing the QRE amounts, the credit amount certified for each taxable year, and the cumulative amount of the tax credit during the credit period. This certificate must be filed with the taxpayer's tax return with the Department of Taxation.

The 2022 Hawaii Form N-346A must be filed by i) March 30, 2023, if you are a calendar year filer or (ii) the day before the last day of the third month following the close of the taxable year, if you are a fiscal year filer. At the time Form N-346A is submitted, a “best estimate” is acceptable if the actual amounts or final numbers are not available. Upon completion, the Department will mail Part II to the QHTB at the address reported on the face of Form N-346A. The taxpayer claiming the credit shall attach the completed Part II of Form N-346A to Form N-346.

Requests for refunds must be completed on or before the end of the 12th month following the close of the taxable year for which the credit may be claimed (i.e. within 1 year).

A “Qualified High Technology Business” means a business that conducts more than 50% of its activities in qualified research, which means:

  1. The same as in section 41(d) of the Internal Revenue Code;
  2. The development and design of computer software for ultimate commercial sale, lease, license or to be otherwise marketed, for economic consideration. With respect to the software’s development and design, the business shall have substantial control and retain substantial rights to the resulting intellectual property;
  3. Biotechnology;
  4. Performing arts products;
  5. Sensor and optic technologies;
  6. Ocean sciences;
  7. Astronomy; or
  8. Non-fossil fuel energy-related technology.
