Must your ABA practice be a licensed professional entity?

The question this pillar answers, and the two it does not

Three questions get tangled together whenever ABA operators talk about structure, and this guide deliberately separates them. The first, answered here, is the gateway: must the practice be a professional entity with licensed ownership at all, or can it be an ordinary LLC? The second is the form question: given the answer, which entity type should you use, a standard LLC, a PLLC, a professional corporation, and can a behavior analyst form it. That question has its own hub, PLLC and entity structures. The third is the capital question: who may hold equity, how outside investment comes in, and when a management company is the right vehicle, covered in MSO and ownership.

Keeping the gateway question separate matters because it is the one that decides everything downstream. If your state does not force a professional entity, the form question becomes a matter of preference, tax, and liability. If it does, the form and capital questions become compliance questions with real teeth. Each state page in this pillar runs the full test against the state's own statutes, quoted verbatim from the official code.

The five-part test

Every state is run through the same five questions, in order, each answered from the state's own statutes. The first question whose answer resolves the matter to open settles it; where all five keep a professional-entity requirement in play, a licensed-owner professional entity is required.

1. Is ABA a licensed profession? If the state has not licensed behavior analysts, no professional-entity rule can attach, and ownership is open at the threshold.
2. Does the state require a professional entity, and who may own it? Many states make the professional corporation or professional LLC optional and leave an ordinary LLC available to any owner; a few compel a licensed-owner form.
3. Does that rule reach ABA? A professional-entity rule binds ABA only if behavior analysis falls within the statute's definition or enumerated list of professional services. Where ABA is omitted, an ordinary LLC governs.
4. Does a corporate-practice doctrine force licensed ownership? A corporate-practice-of-medicine doctrine restricts ownership only where it reaches the profession. Most are medicine-specific and do not reach a behavior analyst licensed outside the medical board.
5. What limits fee-splitting and remuneration? Even where ownership is open, management-fee and referral economics are constrained, usually by the federal anti-kickback and Stark rules and payor contracts rather than a state ABA fee-splitting statute.

The order is the insight. Licensure alone restricts nothing about ownership; a state can license behavior analysts and still leave the ordinary LLC fully available. The requirement only binds when a state both compels a professional form and writes behavior analysis into its reach, and most states have done neither.

The spectrum: from Colorado to Illinois

It helps to picture the 17 states on a spectrum of how the test resolves.

At the most permissive end, the question historically never even started. Colorado went without behavior-analyst licensure until June 2, 2026, when HB26-1425 was signed, so its long-standing open verdict rested on the gateway; with licensure now enacted, effective July 1, 2028, that verdict holds on new footing, because the act licenses individuals without requiring a professional entity or attaching an ownership rule, moving Colorado in beside the licensed-but-open states. Oregon reaches a similar endpoint by a different route: it protects the behavior-analyst title rather than restricting the practice, and its LLC Act expressly permits an ordinary LLC to render professional services with no licensed-ownership requirement.

The broad middle of the spectrum is where most states live: ABA is licensed, but the professional-entity requirement fails somewhere in the chain. In Michigan, the professional form is compelled only for a closed list of learned professions that omits behavior analysts. In North Carolina, ABA is licensed under Article 43, but the professional-entity statutes reach only a closed list of licensing statutes that omits Article 43 (N.C. Gen. Stat. § 55B-2(6)). In Ohio, the professional-association statute reaches a closed list of chapters that omits Chapter 4783, and Ohio enforces no corporate-practice doctrine. Utah and Missouri license the profession but neither state's professional-entity statute reaches it, and neither recognizes a corporate-practice doctrine that would. Georgia and Maryland have no professional LLC at all and expressly permit an ordinary LLC to render professional services, with corporate-practice doctrines that run only to medicine. Texas keeps a famously strict corporate-practice doctrine, but it is medicine-specific and does not reach behavior analysts, so a standard LLC owned by a non-licensee may employ them. Virginia licenses behavior analysts through its Board of Medicine, yet its law lets a corporate entity render a licensed profession through the licensed individual (Va. Code § 54.1-111(F)), and the professional forms remain optional. Tennessee, Wisconsin, and Arizona all offer a professional form without compelling it; Wisconsin's medical-practice restrictions live in Chapter 448 and do not reach a profession licensed under Chapter 440, and Arizona goes furthest, with a 2022 statute letting any health professional practice through any form of business entity and even allowing a professional corporation to sell up to forty-nine percent of its voting shares to non-licensees.

Past the middle sit two states where the answer is open but carries an asterisk. The District of Columbia enacted behavior-analyst licensure in 2024 and the implementing rules are still maturing, and Pennsylvania pairs open ownership with a common-law corporate-practice caveat about clinical control. And at the far end, alone, Illinois imposes an explicit statutory ownership mandate on ABA businesses, examined in its own section below.

Why the answer is usually open: the three exits

Fourteen open verdicts sound like fourteen different stories, but they resolve through three recurring exits, and knowing which exit your state takes tells you what could change it.

• The gateway exit: ABA is not a licensed practice. Oregon protects only the title, and Colorado stood here until June 2026, when HB26-1425 enacted licensure. Where there is no practice license, there is nothing for a professional-entity rule to attach to, and Colorado is the live proof of the corresponding risk: a new licensing act is exactly how this exit closes, which is why newly licensed states deserve a second look.
• The optional-form exit: the professional entity exists, but nothing compels it. Arizona, Colorado, Tennessee, Virginia, Wisconsin, and Michigan all offer a professional form that a behavior analyst may elect, while leaving the ordinary LLC open to any owner. Colorado is the newest arrival here: its 2026 act licenses behavior analysts but requires no professional entity and attaches no ownership rule. The risk here is a statutory mandate converting the optional form into a required one, which is exactly the Illinois story.
• The scope exit: the rule exists but does not reach ABA. North Carolina's and Ohio's professional-entity statutes enumerate closed lists that omit the behavior-analysis licensing article or chapter, Utah's and Missouri's statutes never pick the profession up, and the corporate-practice doctrines of Texas, Maryland, and Georgia run only to medicine. The risk is a list amendment, which is why the state pages track the specific list and its last amendment date.

Even where ownership is open, the fifth axis still runs: management-fee and referral economics are constrained by the federal anti-kickback and Stark rules and by payor contracts, and a few states add their own wrinkle, such as the health-professions anti-solicitation statute that shapes management-fee structures in Texas and Ohio's disciplinary bar on referral remuneration. Open ownership is not unregulated money.

The exception: Illinois and Section 150

Illinois is the one state in this guide where the five-part test runs to the end. Behavior analysts are licensed under the Behavior Analyst Licensing Act, signed in 2022 and administered by the Department of Financial and Professional Regulation, which began issuing licenses on January 15, 2025 (225 ILCS 6/20(a)). The professional forms are licensee-owned: a professional service corporation may issue stock only to individuals licensed in the same or a related professional service (805 ILCS 10/11), and the professional LLC statute defines its reach by general category, any service requiring a license from the Department, which brings ABA within scope without naming it (805 ILCS 185/5).

Then the Act adds the rule that makes Illinois unique: under Section 150, a business organization may provide ABA only if every owner and equity holder who renders the service holds an Illinois behavior-analyst license, and non-licensed owners of existing practices must divest by January 15, 2027 (225 ILCS 6/150). The compliant structure in the meantime is a licensee-owned clinical entity, with outside capital held in a separate management company priced within the fee-splitting limits.

The caveat states: the District of Columbia and Pennsylvania

Two states earn an open verdict with an asterisk, and the asterisks are different.

In the District of Columbia, the caveat is newness. Behavior-analyst licensure was enacted in 2024 (D.C. Law 25-191) and the Board of Psychology's implementing rules are still maturing. Under current law, an ordinary LLC under the Uniform LLC Act may render ABA with non-licensee ownership, and the licensee-owned professional corporation remains optional. But pending rules are the live variable: a scope or ethics rule would change little, while an entity or ownership condition would force re-formation, so the current posture should be confirmed before relying on it.

In Pennsylvania, the caveat is control rather than ownership. A behavior specialist is a State Board of Medicine licensee, but behavior analysis is not the practice of medicine and is not on the restricted-professional-service list (15 Pa.C.S. § 8995), so an ordinary LLC may render ABA with non-licensee ownership. What survives is Pennsylvania's common-law corporate-practice doctrine as a clinical-control caveat: the structure is open, but arrangements that put clinical decisions in lay hands are where the doctrine still has teeth.

Developments to watch in 2026

Illinois rewrites its mandate. SB 712, passed by both houses in 2026, would move Illinois from an ownership mandate to a clinical-decision standard and permit multidisciplinary professional entities, while the January 15, 2027 divestiture deadline of current law keeps running until a change is enacted. This is the single most consequential open question in the guide.

Oregon's SB 951 sets the national high-water mark. Oregon enacted the nation's most aggressive corporate-practice law in June 2025, currently scoped to medical practices with compliance rolling out through 2029. ABA sits outside its core scope today, but an extension to behavioral-health entities would force ownership and structure changes, which is why Oregon carries a moderate change rating despite its open verdict.

Private-equity oversight bills keep arriving, aimed at medicine. North Carolina's Senate Bill 570 (2025) is medicine-only and does not reach ABA, and Pennsylvania's 2025 bills would give the attorney general power to review private-equity-backed healthcare deals, targeting transaction review rather than ABA ownership. The pattern to watch in both states is scope creep: a list amendment or a broadened definition is how an open verdict flips, and the state pages track the specific provisions involved.

Colorado closes the gateway. HB26-1425, signed June 2, 2026, licenses behavior analysts and assistant behavior analysts through a new board in the Division of Professions and Occupations. The open verdict rested on the absence of a license; rerun against the new act, it holds, because the act licenses individuals, effective July 1, 2028, without requiring a professional entity or attaching an ownership rule.

The District's rules land. The Board of Psychology's behavior-analysis rules under the 2024 law are among the last pieces of new licensure in the guide still being written.

How the entity decision connects to the rest of the guide

The gateway verdict shapes every other pillar. Once you know whether your state compels a professional entity, the form question, standard LLC against PLLC against professional corporation, and whether a behavior analyst can form one, is answered in PLLC and entity structures. The capital question, who may hold equity, how a management services organization is priced, and what private equity can and cannot own, is answered in MSO and ownership, and in Illinois the two questions collapse into one. The license the whole analysis is built around, who must hold it and under which board, is covered in licensing and credentialing, and the entity you choose is what gets enrolled and disclosed to payors in Medicaid and insurance, and what holds the facility and records obligations in facility and HIPAA.
