The five-part test in brief
Whether an ABA practice needs a professional entity is a stack of five questions. The licensing act is the gateway, because an unlicensed profession is generally not a professional service and an ordinary entity governs. The professional-entity statute supplies the form and the ownership rule that applies if that form is used. The scope definition decides whether ABA is actually inside that statute. The corporate-practice doctrine, a separate body of law that often lives in the medical practice act or case law rather than the entity statute, is usually what forces licensed ownership and pushes outside capital into a management company. And the fee-splitting and anti-remuneration rules constrain management-fee economics even where ownership is open. The rows below run those five against this state's actual code, quoting the operative language so the position rests on the statute.
Maine, provision by provision
Maine
Ownership openHolding: a non-licensee may freely own an ordinary Maine corporation or LLC that employs BACB-certified behavior analysts. Maine has no behavior-analyst license or registration, so ABA is not a professional service, no professional entity is available or required for it, and the corporate-practice doctrine does not reach it. Maine also has no state anti-kickback statute, so the referral constraint is the federal rule alone.
This matters because the entire professional-entity analysis applies only to a licensed profession; an unlicensed service is governed by ordinary business-entity law. Maine is one of the states that does not license or register behavior analysts, a status confirmed by the national certifying and tracking bodies. A behavior analyst practices in Maine on the strength of national BACB certification, which payers and the state's autism mandate recognize, rather than a state-issued license, and there is no Maine behavior-analyst practice act to place the profession inside the professional-entity framework.
Maine's professional entities exist as an optional vehicle for licensed professions. The professional-corporation and professional-LLC forms are available to persons authorized by law to render a professional service, and their availability presupposes a state license or authorization. Where the state does not regulate a profession, these forms do not come into play and an ordinary corporation or LLC governs.
The scope link is where Maine's answer is fixed. The professional-entity forms reach only a professional service, and a professional service presupposes state licensure or authorization. Because Maine does not license or register behavior analysts, ABA is not a professional service in the state, the professional-entity forms do not apply to it, and an ABA practice is an ordinary business governed by the general corporation and limited-liability-company law. No professional entity is compelled or available on that basis.
The ownership conclusion follows from the gateway finding, and no separate doctrine reaches back to disturb it. Maine's corporate-practice concerns are oriented to medicine and operate through the licensed-professional requirements of the Professional Service Corporation Act, which presuppose a licensed profession. Because Maine does not license behavior analysts, there is no license for a corporate-practice rule to attach to, and the professional-entity forms, which exist only for licensed professions, never engage. An ABA practice is an ordinary business governed by the general corporation and limited-liability-company law, and a non-licensee may own it outright. The conclusion changes only if Maine enacts a behavior-analyst license, at which point the Professional Service Corporation Act and any corporate-practice concern would need to be re-read against the new act.
Open ownership does not mean open economics, and Maine is the cleanest illustration of where the constraint actually comes from, because the state supplies almost none of it. Maine has no state health-care anti-kickback statute, and its profession-specific fee-splitting bars reach licensees rather than an unlicensed ABA practice, so the operative constraint is entirely federal: the federal anti-kickback statute, which reaches any provider billing Medicaid or Medicare and prohibits remuneration to induce referrals of items or services reimbursable by a federal program. The practical consequence is nonetheless the same as in every open-ownership state, because the federal rule alone is sufficient to police it: a management fee must be fixed at fair market value for services actually rendered, not set as a share of clinical revenue or keyed to patient volume or referrals, because a percentage-of-revenue fee is exactly the arrangement the federal statute reaches once the practice bills a federal program.
Reading the five together: behavior analysis is not a licensed or registered profession in Maine (axis one), the professional-entity forms are the vehicle for licensed professions only (axis two), the scope link therefore never engages because ABA is not a professional service (axis three), the corporate-practice doctrine does not reach an unlicensed service (axis four), and there is no state anti-kickback statute, leaving only the federal rule (axis five). Therefore a non-licensee may freely own an ordinary Maine corporation or LLC that employs BACB-certified behavior analysts. The verdict would change only if Maine enacted behavior-analyst licensure.
This entity question sits alongside the other state analyses in the entity decision pillar and the broader ABA compliance knowledge base: how Maine handles professional entity formation and management and ownership structures, its licensing regime, the facility and records rules, and its Medicaid enrollment framework each carry part of the picture.
Outlook: how this verdict could change
Likelihood of change: Moderate. Maine is among a shrinking group of states without a behavior-analyst license, and licensure bills recur in states at this stage, so enactment in a future session is plausible.
What to watch. Any behavior-analyst licensure or registration bill; enactment would move Maine into the professional-entity cascade and could introduce a state referral offense where none exists now.
Disruption if it changes: Moderate. Licensure would make the professional-service definition apply and could bring the professional-entity forms and any ownership conditions into play.
Where professional advice is essential, not optional
Verbatim statutory text is a starting point, not a conclusion. Statutes are amended, agencies issue rules that fill them in, and courts interpret them, so the corporate-practice and fee-splitting questions in particular often turn on interpretation rather than the words on the page. Use this page to locate the operative provisions and to speak from the source, then confirm the current text against the official code and engage qualified Maine counsel before acting. Nothing here is legal, tax, or financial advice.
