Selling a Licensed Professional Practice: Regulatory Transfer Issues in Dental, Veterinary, Accounting, and Engineering Firms

Selling a dental practice, veterinary clinic, accounting firm, or engineering firm involves layers of regulatory and professional licensing complexity that do not exist in ordinary business transactions. Buyers, bankers, and attorneys who handle general M&A competently may not be familiar with the specific rules that govern these transactions — which means the preparation burden falls disproportionately on the selling professional.

The corporate practice doctrine: why non-professionals can't simply own a practice

The corporate practice doctrine is a legal principle, applied differently by state, that restricts or prohibits non-licensed individuals or entities from owning, operating, or controlling a business that provides professional services. The doctrine originated in healthcare but extends in various forms to dentistry, veterinary medicine, optometry, law, accounting, and engineering in different states.

The practical consequence for a sale is this: a PE firm — which is not staffed by licensed dentists, veterinarians, or engineers — cannot simply buy a professional practice and own it the way it would own a manufacturing company. The PE firm cannot directly employ the licensed professionals (in many states), cannot dictate clinical or professional decisions, and may not be legally permitted to own the equity of the professional entity at all.

PE buyers have developed a standard workaround: the Management Services Organization (MSO) structure. Under an MSO structure, the licensed professional retains ownership of the professional entity (the entity that holds the license and employs the licensed staff), while a separate management company owned by the PE firm provides all non-professional services: billing, HR, technology, equipment, real estate, and management. The PE firm earns its economics through the management fee structure and options/warrants that allow it to capture the value of the professional entity indirectly.

Non-transferable licenses: what actually transfers in a practice sale

When a dentist sells their practice, the dental license does not transfer. It cannot — professional licenses are personal, issued to an individual, and they expire when the individual leaves practice or fails to renew. The dental board that issued the license is not a party to the practice sale.

What transfers in a practice sale is the business: the patient records, the goodwill, the lease, the equipment, the staff employment agreements, the insurance contracts, and the contractual relationships with payers. The buyer needs licensed professionals in place on day one of ownership to actually operate the practice legally — but those licensed professionals are people the buyer either employs, retains under a professional services agreement, or acquires through the professional entity structure.

Personal goodwill vs. enterprise goodwill: the tax planning opportunity most sellers miss

In a professional practice, the goodwill is not all the same. Enterprise goodwill is the value attached to the practice itself — its location, brand, patient or client base, referral relationships, systems, and reputation that would continue even if the founding professional left. Personal goodwill is the value attached specifically to the individual professional — patients or clients who come because of that person specifically, and who might leave if they left.

The tax treatment of these two types of goodwill differs significantly in an asset sale. Enterprise goodwill is sold by the practice entity and taxed as a capital gain to the entity (or passes through to the owner). Personal goodwill, if properly documented and elected, can be sold directly by the individual professional to the buyer as a separate transaction, taxed as a capital gain to the individual — bypassing the entity level entirely and potentially avoiding double taxation in a C-corp situation. The broader pre-sale tax planning guide covers how personal goodwill elections interact with entity structure and timing decisions.

For the personal goodwill election to be respected by the IRS, the personal goodwill must actually exist (not all practices have significant personal goodwill — a large multi-provider clinic with strong systems may have minimal personal goodwill), must be documentable (referral patterns, patient retention data, the professional's unique expertise or community presence), and must be allocated at a defensible value supported by an independent appraisal.

Non-compete enforceability in professional practice sales

Non-compete agreements are a standard component of any practice sale — the buyer needs assurance that the selling professional will not immediately reopen across the street and take their patients. But professional practice non-competes have state-specific enforceability considerations that differ from non-competes in ordinary commercial transactions.

In general, non-competes in connection with a business sale are more broadly enforceable than employment non-competes, because the seller is receiving consideration (the purchase price) that is specifically tied to the goodwill being transferred — a court is more willing to enforce a restriction that is genuinely necessary to protect what the buyer paid for. However, some states treat professional non-competes with additional scrutiny because of patient or client access to professional services.

Buyers who acquire professional practices in states with limited non-compete enforceability must account for patient or client attrition risk in their valuation. This is a particularly acute issue in dental or veterinary DSO/MSO transactions in California, where a selling dentist or veterinarian who wants to continue practicing nearby cannot be legally prevented from doing so — and the patient retention risk directly affects what the practice is worth.

Regulatory timeline and closing mechanics: what takes longer than founders expect

Professional practice transactions close on a longer timeline than typical middle market deals, primarily because of regulatory filing and approval requirements. Founders who sign a purchase agreement with a 60-day outside date without accounting for regulatory lead time often find themselves requesting extensions or facing pressure from buyers. The closing conditions guide covers how to negotiate outside date extensions and regulatory approval conditions in the purchase agreement.
