In a dental practice asset vs. stock purchase, the central question is whether you are buying specified practice assets or ownership of the entity that holds them. That choice affects how obligations, contracts, and tax basis are handled. Neither label, by itself, tells you exactly what you will own or what could become your responsibility.
Use the comparison below to prepare a discussion with your acquisition attorney and dental CPA. The available structures and their consequences depend on the seller's entity, tax classification, state professional-ownership rules, and executed agreements. This is a planning guide, not a recommendation for a particular legal or tax structure.
Start by identifying what the seller actually owns
“The practice” may involve several owners: a professional entity operates the office, another entity owns the building, a leasing company owns an imaging unit, and the dentist personally holds a domain or another asset.
Ask counsel to draw a simple ownership map before comparing proposals. List each legal entity, its owners, tax classification, and assets relevant to the sale. A sole proprietorship has no corporate stock to purchase. An LLC interest sale is an equity transaction, but its federal tax treatment cannot be inferred from the LLC label.
The SBA describes both asset and corporate-stock purchases and advises having an attorney review a complete sales agreement, including assets and liabilities. Translate the seller's shorthand into an identified buyer, seller, ownership interest, and list of included property. SBA guidance on selling a business
Compare the two structures without assuming a clean slate
| Question | Asset purchase | Stock purchase |
|---|---|---|
| What changes hands? | Identified assets and agreed assumed obligations | Shares in the corporation that operates the practice |
| What happens to the operating entity? | The seller's entity generally remains with the seller; the buyer operates through its own arrangement | The corporation continues under changed ownership |
| What happens to historical liabilities? | Allocation is negotiated, but exclusions do not eliminate every possible successor-liability exposure | Liabilities remain in the corporation; the buyer acquires an interest in that corporation |
| How do contracts continue? | Assignment, replacement, or consent may be needed | Review change-of-control and other consent provisions even though the entity continues |
Buyers may prefer an asset purchase for greater control over what they acquire; sellers may prefer an equity sale for their own tax and transition objectives. The Michigan Dental Association's overview discusses these competing interests and the need for specialized advisers. Treat those preferences as negotiation context, not proof that either structure is better for your deal. Structuring a Practice Sale: The Basics
Make a transfer worksheet for the items that can cause surprises
Create one row per material item. Use these fields:
Current owner → proposed treatment → required consent or action → evidence → unresolved question.
Start with these dental-specific questions:
- Receivables: Who owns payment for care delivered before closing? Who performs collection work, receives misdirected payments, and bears later adjustments?
- Patient credits and unfinished work: Who handles prepaid amounts, refunds, remakes, and work that crosses the closing date? Have clinical, legal, and accounting owners agree on the treatment.
- Equipment: Is each item owned, leased, or financed? Which liens must be released, and which warranties or service agreements can continue?
- Lease and payer arrangements: Does the actual agreement require assignment consent, a new contract, notice, or a change-of-control review?
- Records: Who becomes custodian, who retains access, and how will lawful patient requests be served? Buying assets does not cancel patients' rights.
- Digital and phone accounts: Can the domain, main number, software licenses, administrator roles, and data be transferred through the providers' approved processes?
Use the broader dental practice due diligence checklist to investigate the underlying evidence. This worksheet records what the chosen structure must do with each finding.
A hypothetical negotiation: the same price, different obligations
Assume two proposals each show a $900,000 headline price. These figures are illustrative, not a valuation benchmark.
In Proposal A, the buyer purchases specified assets. The seller retains pre-closing receivables. A financed scanner must be paid off and its lien released. Patient credits need a negotiated cash adjustment and responsibility schedule. The landlord has not yet consented to assignment.
In Proposal B, the buyer purchases all corporate shares. The corporation retains its receivables, scanner debt, patient-credit obligations, and history. The buyer asks for a debt and working-capital adjustment, disclosure of contingent liabilities, and appropriate contractual protection. The lease still needs a change-of-control review.
The buyer cannot compare these offers using $900,000 alone. Ask the advisers to reconcile the price to cash required at closing, debt remaining afterward, assets received, obligations assumed, and transition spending. Ask the lender to confirm which uses its commitment actually funds. The practice-loan comparison guide helps organize that separate financing question.
Ask for a tax model before agreeing to allocation
Tax allocation divides consideration among the acquired asset categories; it is different from determining what the practice is worth. The IRS explains that an asset sale generally requires separate gain-or-loss treatment for different assets, and that allocation also determines the buyer's basis. Equipment, inventory, and goodwill do not necessarily produce the same result. IRS: Sale of a business
Ask the CPA to show:
- The legal structure and proposed federal and state tax treatment.
- The allocation, support for it, and effect on each party.
- Buyer deductions over time and seller proceeds after taxes and transaction costs.
- Any election needed, eligibility conditions, deadlines, and responsibility for filing.
An ordinary stock purchase does not automatically reset the corporation's underlying asset basis. Special elections and other entity-specific rules can change tax treatment; do not assume they are available or beneficial.
For qualifying asset acquisitions, both sides generally file Form 8594 when its conditions apply. Have the advisers coordinate the agreement and reporting rather than choosing conflicting allocations after closing. IRS: About Form 8594
Finish with a decision record your advisers can challenge
Before accepting a structure, write down the selected approach, alternatives considered, unresolved consents, allocation status, assumed obligations, and evidence required before closing. Ask counsel what representations, indemnities, escrow, insurance, or other protections address identified risks—and what those protections leave uncovered.
Keep the independent valuation separate from this decision. A supported value does not settle transfer mechanics. The purchase is ready to advance when the team can explain what changes hands, what remains outstanding, and who is responsible for each consequence.
