HRS 415A-2 lists the chapters whose licensees may organize a professional corporation, and it names chapter 465, medicine, but not chapter 465D, behavior analysts. Because the two are different chapters and only 465 is enumerated, behavior analysis is not a professional service under the Act, the professional form does not reach ABA, and the standard LLC is the operative choice.
The nine entity criteria at a glance
Is ABA a licensed profession in Hawaii, and under which chapter
Hawaii licenses behavior analysts under HRS chapter 465D, enacted in 2015 and administered by the Department of Commerce and Consumer Affairs, which issues the license to an applicant who has passed the Board Certified Behavior Analyst examination and maintains active BACB certification. The identity of the chapter, 465D and not the medical chapter 465, is the whole of the entity analysis in Hawaii, because the Professional Corporation Act defines the professions it covers by naming licensing chapters, and it names 465 but not 465D. A behavior analyst is a licensed professional, but the professional form reaches only the enumerated chapters, examined next (HRS § 465D-8).
The entity menu: what an ABA practice can use
Hawaii offers a professional corporation under chapter 415A. The Act defines professional service by a closed list of licensing chapters, and because behavior analysis under chapter 465D is not on the list, the professional form is not available to an ABA practice, and the menu reduces to the ordinary business forms.
| Entity | Available for ABA? | Who may own it | When to use it |
|---|---|---|---|
| Standard LLC (HRS ch. 428) | Yes; the prevailing form | Open; a non-licensee may own | The default for an ABA practice; no professional entity is required or available. |
| Professional corporation (HRS ch. 415A) | Not available to ABA | Only persons licensed under an enumerated chapter (415A-2) | Available to the enumerated professions; chapter 465D is not enumerated, so ABA cannot use it. |
| Ordinary corporation (HRS ch. 414) | Yes | Open | An alternative to the LLC where a corporate form is preferred. |
Can a behavior analyst form the professional entity
A behavior analyst cannot form the professional entity in Hawaii, because the professional entity does not exist for behavior analysis. The Professional Corporation Act reaches only the licensing chapters its scope definition enumerates, and 465D is not among them, so there is no professional form for the analyst to elect. This is the absence of an applicable form, not a restriction on the analyst. The behavior analyst forms an ordinary LLC and holds the 465D license as the qualification to deliver services (HRS 415A-2).
Who is allowed to own it
For an ABA practice in Hawaii, anyone may own it. Hawaii has no corporate-practice-of-medicine statute reaching a non-medical profession; the ownership restriction that exists operates through the Professional Corporation Act for the enumerated chapters, and behavior analysis is outside it. A non-licensee founder or an outside investor may own the LLC directly and take distributions. The only ownership-adjacent constraint is the fee-splitting and anti-kickback line governing the money that flows to a non-clinical owner, covered on the ownership page, not a bar on equity itself (HRS ch. 415A; ch. 431:10C-308.7).
Where the two archetypes split
The two archetypes split only lightly in Hawaii, and the diagnostics side adds an option rather than the ABA side losing one.
- ABA-only. A standard LLC owned by anyone, delivering services through licensed behavior analysts. No professional entity, no ownership restriction.
- ABA with in-house diagnostics. A licensed psychologist performing diagnostic evaluations is licensed under chapter 465, which is enumerated in 415A-2, so a psychology line could be housed in a professional corporation owned by psychologists if the practice chose. In practice the psychologist is employed within the ordinary LLC and bills under the psychologist's own credential, keeping a single-entity structure. The behavior-analysis line remains an ordinary LLC regardless.
Because the professional form is unavailable to ABA and elective for psychology, neither archetype is forced into a professional entity, and the standard LLC is the practical structure for both.
Why the Professional Corporation Act does not reach ABA
Hawaii is an enumerated-list state, and the list is the reason ABA sits on the ordinary LLC. HRS 415A-2 defines “professional service” as a service that lawfully may be rendered only by persons licensed under a specified set of chapters, and it enumerates those chapters, running through chapters 442, 448, 453, 455, 457, 459, 461, 463E, 465, 466, 471, and 605, and section 554-2. Chapter 465 is medicine. Behavior analysts are licensed under chapter 465D, a separate chapter enacted decades after the Professional Corporation Act's scope list was written, and 465D was never added to the enumeration.
The consequence is definitional and clean. Because behavior analysis is not a service rendered under an enumerated chapter, it is not a professional service under 415A, the professional-corporation form is not available to an ABA practice, and an ordinary LLC governs by default. This is a sharper result than in states that merely leave the professional form elective: in Hawaii the form is not simply optional for ABA, it is unavailable, because the profession is outside the Act's scope entirely. The one item to watch is an amendment to 415A-2 adding chapter 465D, which would make the professional form applicable and could introduce a same-profession ownership constraint. The Hawaii entity-decision page tracks that scope list (HRS 415A-2).
Naming the entity
An ABA-only practice in Hawaii uses an ordinary LLC name with a standard designator, Limited Liability Company, LLC, or L.L.C., and may not use a professional designator, since the professional form is not available to it. The name must be distinguishable from existing Hawaii entities and must not imply a profession the entity is not authorized to practice. Clearing the name with the Department of Commerce and Consumer Affairs at formation avoids a later change (HRS ch. 428, naming provisions).
Why choosing the entity is only half the question
Choosing the entity settles the form, not the operation. The standard LLC answers what the practice is; it does not answer who may hold equity as outside capital enters, how a management company would be priced, how the 465D credential is maintained, or how the entity enrolls with payers. Those are the questions the rest of the guide answers, and in Hawaii the entity choice is effectively settled by the scope list in favor of the ordinary LLC, so the value is in the structuring on top of it.
Tax treatment as a separate layer
Entity form and tax classification are separate layers. A single-member Hawaii LLC is a disregarded entity by default, a multi-member LLC is a partnership, and either may elect S-corporation or C-corporation treatment with the IRS independent of the state-law form. Because ABA uses an ordinary LLC in Hawaii, no tax election is constrained by a professional-form requirement. This is not tax advice; make the election with a tax advisor (26 U.S.C.; IRS Form 8832, Form 2553).
Multistate practice and foreign qualification
A practice organized elsewhere that begins serving Hawaii clients must foreign-qualify its home entity with the Department of Commerce and Consumer Affairs, or form a Hawaii entity, before transacting business in the state. Because Hawaii imposes no professional-entity requirement on ABA, a foreign ordinary LLC qualifies without a professional-form or licensed-ownership hurdle. The gating item is the clinical credential: the behavior analysts serving Hawaii clients must hold 465D licensure regardless of where the entity is organized. A multistate operator applies the strictest-state rule, and Hawaii is not the strict state on the entity axis.
How this connects to the rest of your compliance stack
The entity is one decision in a stack. In Hawaii the entity choice is a standard LLC and the real work is ownership structuring, payer enrollment, and maintaining the chapter 465D credential. See the Hawaii entity-decision page for the gateway question, the Hawaii ownership page for outside capital, the Hawaii licensing page for the credential, the Hawaii Medicaid page for enrollment, and the Hawaii facility page for records and premises. The compliance guide ties them together.
Forming the entity in Hawaii: the sequence
- Confirm the archetype. ABA-only, or ABA plus in-house psychology. The second adds an optional professional-corporation option for the psychology line; the ABA line is a standard LLC either way.
- Form the LLC. File articles of organization with the Department of Commerce and Consumer Affairs under HRS chapter 428.
- Clear the name. Use an ordinary LLC designator; avoid any professional designator or a misleading professional name.
- Adopt an operating agreement. Set ownership and management, and reserve clinical authority to a licensed behavior analyst clinical director.
- Credential and enroll. Ensure the behavior analysts hold 465D licenses and enroll the entity with Med-QUEST and commercial payers under its own NPI and tax ID.
- Layer ownership and management terms. Structure any outside capital against the fee-splitting and anti-kickback rules the ownership page covers.

Where professional advice is essential, not optional
Hawaii's entity answer is clean, a standard LLC, open ownership, no professional form available, so counsel matters in narrow situations: structuring outside investment against the fee-splitting and anti-kickback rules; housing an in-house psychology line where the professional-corporation option becomes available; and multistate expansion where a stricter state governs. A behavior analyst forming a solo LLC generally does not need bespoke entity counsel but should have the operating agreement and payer enrollment reviewed.
