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 New York

It helps to picture the 51 jurisdictions 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. California sits nearby for ABA-only practice specifically: no behavior-analyst license has ever been enacted there either, so the state's mandatory professional-corporation statute, Moscone-Knox, structurally cannot reach ABA-only work, though it applies in full the moment a licensed psychologist joins the practice for in-house diagnostics, which is why California ultimately lands in the caveat group below rather than the clean-open group.

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.

Five of the wide-build states join this open middle by their own distinct routes. Indiana's professional-corporation statute is elective and, even when chosen, requires only one Indiana-licensed shareholder. Minnesota's Professional Firms Act reaches psychology by name but omits behavior analysis from its enumerated categories entirely. Connecticut's Professional Service Corporation Act uses a closed, named list of professions, and despite Connecticut's reputation as a strict corporate-practice state for medicine, that list does not include behavior analysts. Louisiana never built a general professional-corporation statute at all, "professional corporation" there is a term of art reaching only medicine and dentistry by direct cross-reference. Nevada and South Carolina both keep the professional-entity form genuinely elective, with South Carolina's statute stating outright that declining the election does not affect the right to use any other business entity form.

The remaining states broaden the same open middle without changing its shape, and they sort into four recognizable mechanisms. The largest is the group that never licensed behavior analysts at all, so the professional-entity framework has nothing to attach to: Delaware, Idaho, Maine, New Hampshire, New Mexico, and West Virginia join California and Colorado's former posture at the gateway end, and Idaho and New Mexico sit there doubly protected, having also affirmatively abandoned the corporate-practice-of-medicine doctrine, Idaho by a 2016 Board of Medicine policy and New Mexico by a 1987 Attorney General opinion. A second group licenses ABA but sits outside its own professional-entity act because that act enumerates a closed list of professions that never added behavior analysis: Hawaii (HRS 415A-2 omits chapter 465D), Iowa (whose list was amended to add allied mental-health professions but left behavior analysts off), and Kansas (a closed, one-type-per-profession list) reach the same result as North Carolina, Ohio, and Minnesota. A third, distinctive cluster licenses behavior analysts through the state psychology board rather than a standalone or medical board, so the corporate-practice question routes through psychology, which carries no doctrine reaching ABA: Montana, North Dakota, South Dakota, and Wyoming. And the rest license the profession under a generic entity statute whose corporate-practice bar runs only to physicians, leaving the professional form elective and the ordinary LLC open to any owner: Alabama, Alaska, Mississippi, Nebraska, Oklahoma, Rhode Island, and Vermont. Arkansas is the one state in this group that resolves open but earns a change flag, because it regulates behavior analysts by registration rather than licensure under a 2025 act whose implementing rules are still being written.

Past the middle sit seven states where the answer is open but carries a real asterisk, examined together below: the District of Columbia, Pennsylvania, California, Florida, Massachusetts, Kentucky, and Washington, whose asterisk is the heaviest of the group. And at the far end, two states impose an explicit ownership restriction rather than an open verdict: Illinois' statutory mandate, examined in its own section below, and New York, which licenses ABA and writes it directly into a same-profession-only ownership statute with no allied-profession or minority lay-ownership exception.

Why the answer is usually open: the three exits

Twenty-one open verdicts sound like twenty-one 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. California stands here too for ABA-only practice specifically, since no license has ever been enacted. Across all fifty states and the District, this exit is the single largest, taken by nine jurisdictions that do not license behavior analysts at all: California, Delaware, Idaho, Maine, New Hampshire, New Mexico, South Carolina for ABA-only practice, West Virginia, and, until its 2026 licensure act, Colorado. 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. Idaho and New Mexico sit here doubly protected, having also affirmatively abandoned the corporate-practice-of-medicine doctrine, Idaho by a 2016 Board of Medicine policy and New Mexico by a 1987 Attorney General opinion, so even a future licensing act would not by itself force licensed ownership.
• The optional-form exit: the professional entity exists, but nothing compels it. Arizona, Colorado, Tennessee, Virginia, Wisconsin, Michigan, Indiana, Nevada, New Jersey, and South Carolina all offer a professional form that a behavior analyst may elect, while leaving the ordinary LLC open to any owner. South Carolina's statute is the most explicit in the guide about it, stating directly that not electing professional-corporation status does not affect the right to use any other business form. The risk here is a statutory mandate converting the optional form into a required one, which is exactly the Illinois story and the New York story. New Jersey is the reverse lesson: its Professional Service Corporation Act is elective, its LLC Act is general, and the strict rules the state is known for were written by the medical and psychology boards for their own licensees, not by the behavior analyst board. A distinctive cluster sits inside this exit: Montana, North Dakota, South Dakota, and Wyoming all license behavior analysts through the state psychology board rather than a standalone or medical board, which means the corporate-practice question routes through psychology, and psychology carries no doctrine that reaches ABA, so the elective professional form stays optional and ownership stays open.
• 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, Minnesota's and Connecticut's enumerated lists omit behavior analysis even though they reach psychology by name, Louisiana's professional-corporation concept reaches only medicine and dentistry by definition, and the corporate-practice doctrines of Texas, Maryland, and Georgia run only to medicine. The tail states deepen this exit rather than change it: Hawaii, Iowa, and Kansas all license behavior analysts yet sit outside their own professional-entity acts because those acts enumerate a closed list of professions that never added ABA, the same mechanism as North Carolina and Ohio and, in the caveat group, Minnesota. Iowa is the sharpest illustration, its legislature amended the list to add marital-and-family therapy, mental-health counseling, and social work, all licensed under the same chapter as behavior analysts, but left behavior analysts off, so the professional-corporation form is simply unavailable to an ABA practice and an ordinary LLC governs by default. The risk in every scope-exit state 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 strict states: Illinois and New York

Two states in this guide run the five-part test all the way to the end, and they get there by different routes.

Illinois is the explicit-mandate case. 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 Section 150 adds the rule that makes Illinois unique among the original 17: 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).

New York reaches the same destination through a name-specific statute rather than a general mandate layered on top of an existing form. Article 167 of the Education Law licenses behavior analysts, and New York's LLC Law and Business Corporation Law were separately amended to name applied behavior analysis services directly: every member of a PLLC organized to render ABA must be licensed under Article 167, and PC shares may be issued only to individuals authorized to practice the profession the corporation renders (N.Y. LLC Law § 1203; N.Y. Bus. Corp. Law § 1507). There is no allied-profession exception and no minority lay-ownership carve-out; ownership is licensee-only in full.

New Jersey, which an earlier version of this guide placed in this group, does not belong here, and the reason is instructive. Its Professional Service Corporation Act, N.J.S.A. 14A:17, lets licensed persons form a professional corporation and restricts its owners to same-or-closely-allied licensees, a list that includes psychology and excludes behavior analysis. But the Act is permissive, New Jersey has no PLLC statute, its LLC Act permits any lawful purpose, and the rule that channels a profession into licensee-owned entities comes from that profession's board: the medical board wrote one (N.J.A.C. 13:35-6.16, the rule enforced in Allstate v. Northfield), the psychology board wrote one (N.J.A.C. 13:42-7.2), and the behavior analyst board, in its 2024 rules, wrote none. New Jersey is open for ABA-only practice and strict the moment a psychologist or physician joins it.

The caveat states: seven answers with an asterisk

Seven states earn an open verdict with an asterisk, and the asterisks are different in each case, worth reading rather than assuming.

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.

In California, the caveat is archetype-dependent, and it is a genuine split rather than a soft caveat. ABA-only practice is open because California has never licensed behavior analysts, so Moscone-Knox, the state's mandatory professional-corporation statute, structurally cannot reach it. The moment the same organization employs a licensed psychologist for in-house diagnostics, that piece of the business flips entirely: Moscone-Knox applies in full, an LLC becomes unavailable for it, and ownership caps at the statutory licensee-majority split. A practice offering both service lines needs two separate entity analyses, not one.

In Florida, the caveat is a genuinely unresolved legal question rather than a settled answer in either direction. Florida's mandatory professional-entity statute, Chapter 621, is triggered by services requiring a license "as a condition precedent," and Florida's ABA credentialing runs on APD certification for most practitioners rather than a dedicated license. Whether that certification counts as the kind of "license" Chapter 621 contemplates has not been tested, so the open verdict here rests on an interpretation, not a closed statutory answer, unlike most of the states in the clean-open column.

In Massachusetts, the caveat is structurally similar to Florida's: ABA is not named in the Professional Corporation Law's enumerated list of covered professions, but the statute's broader catch-all clause, for services "rendered only pursuant to a license," has never been tested against behavior analysis specifically. The absence of ABA from the named list is not, by itself, a settled negative answer.

In Kentucky, the caveat runs the opposite direction from most of this group: the professional-entity form is confirmed elective, not a live legal question, but where it is elected, ownership is genuinely restricted to "qualified persons" under KRS 274.005(4), not open to any lay investor the way an elective form in a state like South Carolina or Nevada would be. The caveat here is about what happens if the form is chosen, not about whether the statute applies.

In Washington, the asterisk is the heaviest in the group and points the other way. The entity statutes are elective, and on their face a non-licensee may own an LLC that employs licensed behavior analysts. But Washington's corporate-practice doctrine is common law, and the Supreme Court in Columbia Physical Therapy v. Benton Franklin Orthopedic Associates, 168 Wn.2d 421 (2010), stated it as forbidding any business entity from practicing a licensed profession through employees absent legislative authorization, with the licensee-owned professional entities as the authorization. Behavior analysis has required a license since 2015 and chapter 18.380 supplies no entity authorization. No court has applied the doctrine to ABA, and codification bills are pending. The conservative structure is a licensee-owned PLLC with outside capital in a management company; the state page treats Washington as strict by doctrine, untested.

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.

Newly licensed states are the ones to re-check. The gateway exit closes when a state enacts a licensing act, and several no-license states have active or recent legislative interest. Colorado is the live proof, moving from no-license to licensed in June 2026 without attaching an ownership rule; the states still at the gateway, Delaware, Idaho, Maine, New Hampshire, New Mexico, and West Virginia, are where a future licensing act would first need to be read against the professional-entity statute, though Idaho's and New Mexico's disavowal of the corporate-practice doctrine means even a license would not by itself force licensed ownership.

Arkansas's registration rules are still being written. Arkansas regulates behavior analysts by registration rather than licensure under a 2025 act, and its implementing rules were not final as of this writing. The open verdict rests on the registration-not-licensure distinction and on the professional-entity statute not reaching registrants; both should be re-checked as the board completes rulemaking, which is why Arkansas alone among the newly covered states carries a moderate change rating.

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.

New York joins Illinois as a licensed-owners-only state; New Jersey does not, and Washington carries the heaviest caveat. This guide corrected two classifications in August 2026 on re-verification of the primary sources. New Jersey moved from strict to open because its professional corporation statute is elective and its behavior analyst board has adopted no entity rule; the strict rules belong to the medical and psychology boards. Washington moved from clean-open to open-with-caveat because its Supreme Court states the corporate-practice doctrine as reaching any licensed profession absent legislative authorization, which the elective entity statutes do not displace. The pattern in both errors was the same: a real statute or case, read as reaching behavior analysis when it reaches a different profession, or read as not reaching it when its stated scope does.

Connecticut's reputation and its actual statute point different directions. Connecticut is correctly known as a strict corporate-practice state for medicine, but its Professional Service Corporation Act uses a closed, named list of professions that does not include behavior analysts, and its corporate-practice doctrine is textually anchored to the practice of medicine specifically. A general reputation for strictness does not transfer automatically to every licensed profession in a state; the enumerated list is the only reliable answer for a specific profession.

Louisiana's entity-ownership question is settled, but its licensing chapter is not. Ownership is open for ABA in Louisiana, "professional corporation" there is a defined term reaching only medicine and dentistry. The far more consequential Louisiana-specific risk is unrelated to entity structure: the state's entire ABA licensing chapter carries a statutory sunset of July 1, 2028 under R.S. 37:3718, absent legislative reauthorization.

South Carolina's open verdict has a separate licensure deadline attached. The entity-ownership answer is clean and open, but individuals previously approved as behavior support providers by DHHS without a Chapter 75 license must obtain full licensure by December 31, 2026, a live, approaching deadline as of this writing that affects who may lawfully practice at all, independent of the entity question.

Minnesota and Indiana are both running on year-old frameworks. Minnesota's licensure took effect January 1, 2025; Indiana's 2021 statute did not become operationally licensable until May 2025. Both states resolve to open ownership today, but both are worth re-checking as their respective boards continue to build out rulemaking.

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.
