Missouri does not offer a professional limited liability company. Practices use either a standard LLC (Missouri Limited Liability Company Act, RSMo §§ 347.010 to 347.187), which any person may form and which Missouri's lightly enforced corporate-practice posture leaves open to non-licensee owners, or a professional corporation (RSMo Chapter 356), which must be licensee-owned and whose formation depends on a certificate from the licensing authority (RSMo § 356.041). Behavior analysts are licensed through the behavior analyst advisory board within the State Committee of Psychologists (RSMo §§ 337.300 to 337.345).

Is ABA a licensed profession in Missouri, and under which board
Yes. Missouri licenses behavior analysts and assistant behavior analysts, with oversight by a behavior analyst advisory board that sits within the State Committee of Psychologists, administered through the Division of Professional Registration (RSMo §§ 337.300 to 337.345). Licensure is built on national board certification (RSMo § 337.315), and Missouri's definition of applied behavior analysis is drawn to exclude psychotherapy and psychological testing (RSMo § 337.300). Because behavior analysis is licensed, the professional-entity question is live, but Missouri answers it without a PLLC.
The entity menu: there is no PLLC, so here is what you use
Missouri does not offer a professional limited liability company. Practices use either a standard LLC or a professional corporation, and because Missouri's corporate-practice posture is light, the standard LLC is usually the cleaner choice.
| Entity | Available for ABA? | Who may own it | When to use it |
|---|---|---|---|
| Standard LLC (RSMo §§ 347.010 to 347.187) | Yes | Any person; non-licensee owners workable | The usual choice. Simple, flexible, no annual report, and an operating agreement carries the governance. |
| Professional corporation (PC) (RSMo Chapter 356) | Yes | Licensed shareholders, directors, and officers | If you want a corporate professional form. Requires a certificate from the licensing authority. |
| Professional LLC (PLLC) | Not offered | n/a | Missouri has no PLLC; use one of the forms above. |
Can a behavior analyst form the professional entity
Yes. Because behavior analysis is licensed in Missouri, a licensed behavior analyst can form a standard LLC to render it, or a professional corporation under Chapter 356. A standard LLC can be formed by any person and does not turn on the profession at all (RSMo §§ 347.010 to 347.187), so the eligibility question is straightforward. For the professional corporation, the practitioners must be licensed, and the form is keyed to the licensing authority, which here is the behavior analyst advisory board within the State Committee of Psychologists. The standard LLC is the simpler route and avoids the certificate step described below.
Missouri's missing PLLC is not a constraint. The standard LLC does the job, with no annual report to file and a corporate-practice posture light enough that non-licensee ownership is workable.
Who is allowed to own it
It depends on the form. A standard LLC may be owned by any person, and Missouri's corporate-practice doctrine is limited and lightly enforced, so non-licensee ownership of an ABA practice operating as a standard LLC is generally workable, a notable contrast with the strict states. A professional corporation, by contrast, restricts its shareholders, directors, and officers to licensed professionals. So if you want non-licensee or outside ownership, the standard LLC is the path; if you want a licensee-only corporate professional form, the Chapter 356 PC is available. As always, confirm the precise treatment for your model with counsel, since payor expectations can favor licensee involvement even where the corporate-practice doctrine does not require it.
The professional-corporation certificate
The one front-end step unique to the professional corporation is the certificate. Missouri's Chapter 356 ties professional-corporation formation to the licensing authority, which issues certificates and may set fees by rule (RSMo § 356.041); the licensing authority for behavior analysts is the behavior analyst advisory board within the State Committee of Psychologists. A standard LLC requires no such certificate. This is the practical reason the standard LLC is usually faster to stand up, with the PC reserved for situations where its corporate features are specifically wanted.
Naming the entity
A standard Missouri LLC uses an ordinary limited-liability-company designator and must be distinguishable on the Secretary of State's records. A professional corporation's name is regulated under Chapter 356 and must comply with the licensing board's rules, typically carrying a professional designation such as P.C. or professional corporation, and must be distinguishable from other registered Missouri entity names (RSMo § 356.071). If you use a standard LLC, the ordinary designator applies. 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 Missouri is comparatively open: a standard LLC can carry non-licensee owners, and Missouri's light corporate-practice posture means ABA practices often do not need the management-company structure that strict states force. A professional corporation, by contrast, must be licensee-owned. Decide the entity and the ownership together, particularly if you are weighing investors or a multistate model.

Tax treatment as a separate layer
Entity form and tax classification are separate choices. A Missouri 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 professional corporation is a corporation for tax purposes unless it makes an S election. A Missouri practical point is that the state does not require LLCs to file annual reports, which lowers ongoing maintenance for the LLC form. The tax choice sits on top of the entity analysis; decide it with a tax adviser.
Multistate practice and foreign qualification
If you operate beyond Missouri, the Missouri entity 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, which may be far stricter, including states that require a PLLC or licensee-only ownership. A non-licensee-owned LLC that works in Missouri can be impermissible elsewhere, so multistate groups usually standardize on a structure that satisfies the strictest state in the footprint. 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. Whether you need a management company depends on the form and ownership you want; in Missouri you often do not. See the Missouri MSO and ownership page.
- Licensing and credentialing. The individuals delivering ABA must hold the Missouri behavior-analyst license. See licensing and credentialing.
- Payor and Medicaid enrollment. The entity and its ownership are disclosed at enrollment and revalidation. See Medicaid and insurance mandates.
Forming the entity in Missouri: the sequence
- License the practitioners. Behavior analysts licensed through the behavior analyst advisory board within the State Committee of Psychologists (RSMo §§ 337.300 to 337.345).
- Choose the form. A standard LLC for most practices; a professional corporation if you want the corporate professional form. There is no PLLC option.
- Clear the name. Ordinary LLC designator for a standard LLC, or a professional designation for a PC (RSMo § 356.071).
- Obtain the licensing-authority certificate if forming a PC. Chapter 356 ties PC formation to a certificate from the licensing authority (RSMo § 356.041); the standard LLC requires none.
- File with the Secretary of State and adopt an operating agreement. Missouri treats the operating agreement as the core governing document and does not require an LLC annual report.
- Confirm with Missouri counsel. Especially on any non-licensee LLC ownership and any multistate footprint.

Where professional advice is essential, not optional
Missouri's lack of a PLLC and its light corporate-practice posture make the standard LLC attractive, but the professional-corporation certificate step, payor expectations, and any multistate footprint still warrant counsel. Confirm the form, the ownership, and the tax treatment with a Missouri attorney and a tax adviser before you file.
