What entity should your ABA practice use in Kentucky?

Is ABA a licensed profession in Kentucky, and under which board

Yes, and through a dedicated board. Kentucky created the Kentucky Applied Behavior Analysis Licensing Board in 2010, one of the earliest stand-alone ABA boards in the country, and the board licenses behavior analysts and assistant behavior analysts tied to Behavior Analyst Certification Board credentials (KRS Chapter 319C, especially KRS 319C.080). The board's powers to regulate practice are set out in KRS 319C.060, and its code of ethics and standards of practice incorporate the BACB ethics code (201 KAR 43:040). Nothing in the chapter or the board's regulations addresses the entity a licensee practices through or who may own it. The licensure mechanics are on the Kentucky licensing and credentialing page.

The entity menu: what an ABA practice can use

Kentucky has a professional service corporation statute and, within its LLC Act, a professional limited liability company. Both attach only to the eighteen listed professions, and both are elective for those. For an ABA-only practice the menu is the ordinary forms.

Can a behavior analyst form the professional entity

No, and the consequence is favorable. Kentucky's professional-entity statutes do not define "professional services" by a principle; they define it by a list, and the list is the same in both: physicians, osteopaths, optometrists, podiatrists, chiropractors, dentists, nurses, pharmacists, psychologists, occupational therapists, veterinarians, engineers, architects, landscape architects, certified public accountants, public accountants, physical therapists, and attorneys (KRS 275.015(26); KRS 274.005). Behavior analysts are not on it. A professional limited liability company is an LLC organized "for purposes that include, but are not limited to, the providing of one (1) or more professional services" (KRS 275.015(25)), so an ABA LLC, providing no listed service, is not a PLLC and its members need no license. The Professional Service Corporation Act is elective on its face, "may incorporate," and unavailable to ABA on its definition. The absence means an ABA practice cannot elect into the professional regime, and it also means the regime's licensed-owner rules cannot reach it.

Who is allowed to own it

For an ABA-only practice, anyone. The only Kentucky entity-law provisions that restrict ownership by profession are the professional-entity rules, and they attach only to the listed professions. An ABA LLC is an ordinary LLC that any person may own. Kentucky's licensing board has adopted no rule on the business form or ownership of a licensee's practice, and no Kentucky authority extends a corporate-practice doctrine to behavior analysis. A non-licensee may own the LLC and take distributions. Clinical control belongs to the licensed behavior analysts because practicing without a license is prohibited by the chapter and carries a fine under KRS 319C.990.

Where the two archetypes split

Psychologists are on the list, so a practice that adds an in-house psychologist for diagnostic evaluations adds a component that both professional-entity statutes govern. Kentucky's rules for that component are more flexible than most states'. The Professional Service Corporation Act allows individuals "licensed to render related professional services such that applicable licensing laws and regulations would not prohibit the practice of such multiple professional services through a single business partnership" to form one professional service corporation together (KRS 274.015(1)), and the LLC definition of a PLLC contemplates "one (1) or more professional services." Because behavior analysis is not a professional service under either statute, those provisions do not let a behavior analyst co-own the psychology component; they govern which listed professions may combine. The practical structure for the diagnostics archetype is therefore a standard ABA LLC that anyone may own alongside a psychology PLLC or PSC owned by the psychologist, with a management company serving both. The Board of Examiners of Psychology's own rules on practice through entities govern the psychology piece and should be confirmed.

Why the closed list decides Kentucky

Kentucky's entity law makes no distinction between licensed and unlicensed services; it distinguishes listed from unlisted. That design has a consequence most operators miss: the 2010 licensure act put behavior analysis on the same footing as any other licensed occupation, and nothing more. The legislature amended the entity statutes for other professions when it wanted them inside the regime, and it has not done so for behavior analysts. The LLC Act's flexibility runs the other way as well: because an LLC may be organized for any lawful purpose including professional services, and because "if the purpose for which a limited liability company is organized or its activities make it subject to one (1) or more special provisions of law, the limited liability company shall also comply with those provisions" (KRS 275.005), the licensing board could in theory adopt a rule that becomes such a special provision. It has not. Watch the Kentucky Administrative Regulations under Title 201, Chapter 43, and any bill amending KRS 275.015(26) or KRS 274.005.

Naming the entity

A Kentucky LLC name must contain "limited liability company" or "limited company" or an abbreviation such as "LLC" or "LC," and must be distinguishable on the Secretary of State's records under the business entity filing act. No professional designator applies to an ABA LLC; a PLLC or PSC in the diagnostics archetype uses the designator its statute requires. Clear the name with the Secretary of State before filing.

Why choosing the entity is only half the question

Picking the form is one decision. Who may own it, and how outside capital comes in, is the other, and in Kentucky both are open for ABA-only practice: a standard LLC that anyone may own, with outside capital in the clinical entity itself if the parties want it there. The management company earns its place when a psychology or medical component enters the structure. Kentucky's Medicaid rate environment, covered on the Medicaid page, matters more to a Kentucky operator's economics than the entity question does.

Tax treatment as a separate layer

Entity form and tax classification are separate choices. A Kentucky LLC is taxed by default as a sole proprietorship or partnership depending on the number of members and can elect corporate or S-corporation treatment; a corporation is a corporation unless it makes an S election. Kentucky's limited liability entity tax applies to LLCs and corporations alike, so it does not favor one form over another. Decide the tax layer with a Kentucky tax adviser.

Multistate practice and foreign qualification

If you operate beyond Kentucky, the Kentucky LLC is only your home-state piece. To deliver services in another state you generally register there as a foreign entity and meet that state's own ownership and entity rules. Illinois, across the Ohio River, mandates licensed ownership of ABA businesses by January 15, 2027; Ohio and Tennessee are open on their own reasoning. Multistate groups usually standardize on a structure that satisfies the strictest state in the footprint rather than the most permissive. See the practice expansion and sale page for the multistate view.

How this connects to the rest of your compliance stack

Entity choice is one layer. Others interact with it:

• Ownership and outside capital. Kentucky is open for ABA-only practice; the management company matters for a psychology component. See the Kentucky MSO and ownership page.
• Licensing and credentialing. Every clinician delivering ABA holds the KRS 319C license, and the board's ethics code applies. See licensing and credentialing in Kentucky.
• Payor and Medicaid enrollment. The entity and its ownership are disclosed at enrollment and revalidation. See Kentucky Medicaid and the insurance mandate.

Forming the entity in Kentucky: the sequence

1. License the practitioners. Behavior analysts and assistants licensed by the Kentucky Applied Behavior Analysis Licensing Board under KRS 319C.080.
2. Decide the archetype. ABA-only, or ABA plus in-house psychology. The second answer adds a psychology PLLC or PSC.
3. Form the ABA entity. A standard LLC by articles of organization with the Secretary of State under KRS Chapter 275.
4. Clear the name. Ordinary LLC designator; check availability before filing.
5. Adopt an operating agreement. Set ownership and management, and reserve clinical authority to a licensed behavior analyst clinical director.
6. If diagnostics are in-house, form the psychology entity. A PLLC or PSC owned by the psychologist; management services agreement at a fixed fair-market-value fee.
7. Watch the lists. An amendment adding behavior analysts to KRS 275.015(26) or KRS 274.005 would bring ABA inside the professional regime.
