Key Takeaways for Dental Practice Sellers
- Deal structure shapes what you keep after tax. Asset sales spread price across assets with mixed tax treatment. Stock sales often apply long-term capital gains to the full gain.
- Buyers usually favor asset sales for a stepped-up basis and more control over liabilities. Sellers often favor stock sales to reduce ordinary income on equipment recapture and non-competes.
- Entity type can be the biggest driver of after-tax results. S-corps often avoid double taxation, C-corps can face it in asset deals, and LLCs follow their tax election.
- Allocation is negotiated in the LOI and reported on Form 8594. Shifting more value to goodwill can reduce a seller’s federal tax bill.
- McLerran & Associates focuses solely on sell-side guidance and models both private-buyer and DSO paths so dentists can see their real after-tax options.

Asset Sale vs. Stock Sale Defined: What the Buyer Actually Purchases
In an asset sale, the buyer purchases specified assets such as equipment, goodwill, patient records, the practice name, and leasehold improvements. The buyer assumes only the liabilities both sides agree to include. The selling entity, such as the professional corporation or LLC, stays with the seller. In a stock sale or entity sale, the buyer purchases the ownership interest in the entity itself and steps into its history, contracts, and liabilities. The entity stays in place and only the owner changes. The table below summarizes how the two structures differ on points that usually matter most to a seller.
| Attribute | Asset Sale | Stock Sale |
|---|---|---|
| What is transferred | Specified assets and agreed liabilities only | Ownership interest in the entity, with all assets and liabilities inside it |
| Liability exposure to buyer | Limited to assumed liabilities, with most historical liabilities staying with seller | Buyer inherits all entity liabilities, both known and unknown |
| Buyer’s tax basis | Stepped-up to purchase price allocated across asset classes under IRC Section 1060 | Cost basis in shares only, with no step-up in underlying assets without a special election |
| Seller’s tax character | Mixed: goodwill usually at capital gains rates, equipment recapture and non-competes at ordinary income | Typically long-term capital gains on the entire stock gain, subject to holding period |
| Transfer mechanics | Each asset assigned individually, contracts may require consent, employees technically rehired | Ownership interest transferred while contracts and employees remain inside the entity |
| Prevalence in dental transitions | Most common structure in dental practice sales | Less common, usually tied to specific entity types or non-transferable contracts |
Asset sales remain the overwhelming norm in dentistry. Stock sales tend to appear in narrower situations such as particular corporate structures, non-assignable contracts, or distinct buyer preferences.
Why Buyers Often Prefer Asset Sales While Sellers May Favor Stock Sales
Buyers usually prefer asset deals for two main reasons. They receive a stepped-up tax basis in every acquired asset, which creates larger depreciation and amortization deductions in future years. They also inherit only the liabilities they agree to assume, which limits exposure to historical issues.
Sellers can find stock sales appealing because the entire gain may qualify for long-term capital gains rates, with a top federal rate of 20% plus a potential 3.8% Net Investment Income Tax (NIIT). Asset deals can produce ordinary income on depreciation recapture for equipment and on non-compete payments, which can reach rates up to 37% federally.
Because buyers usually benefit more from asset deals, a seller who prefers a stock deal is asking the buyer to accept a weaker tax position. That request often leads to a price adjustment. Structure functions as a price-adjustment lever that both parties can negotiate. A seller who understands this tradeoff can approach structure as a discussion point instead of accepting the buyer’s first draft.

How Allocation Shapes Tax on a Dental Practice Sale
In an asset sale, the purchase price does not get taxed as one lump sum. The price is allocated across asset classes, and each class can receive different tax treatment. Both buyer and seller must report that allocation to the IRS on Form 8594 (Asset Acquisition Statement Under Section 1060), filed with their tax returns for the year of the sale. The IRS compares the two filings, and mismatches can draw attention.
The allocation follows a fixed order under IRC Section 1060’s residual method, moving from cash and receivables through tangible property and intangibles. Goodwill and going-concern value come last. They represent the residual, or whatever remains after all other classes are filled. From the seller’s perspective, the main allocation lines usually work as follows:
- Goodwill and going-concern value (Class VII): Often the largest slice of a dental practice sale price. Gain here is generally taxed at long-term capital gains rates, with a top federal rate of 20% plus the 3.8% NIIT for high earners, assuming the holding period requirement is met.
- Equipment and furniture (Class V): Subject to depreciation recapture under IRC Section 1245, which generally is taxed at ordinary income rates up to the amount of prior depreciation. If equipment was fully expensed through bonus depreciation or Section 179, the entire sale price of that equipment can become ordinary income.
- Non-compete and consulting agreements (Class VI): Generally treated as ordinary income, taxed at rates that can reach 37% federally.
- Patient records and other intangibles (Class VI): Tax character depends on how the parties classify them in the allocation and on the specific facts of the deal.
Allocation terms are negotiated in the letter of intent and then in the purchase agreement. Sellers can request a defensible allocation that increases capital gains treatment instead of accepting the buyer’s first proposal. Every dollar shifted to goodwill can reduce the seller’s federal tax compared with dollars assigned to ordinary income categories. Allocation remains practice-specific and tied to the valuation, so no single percentage mix fits every transaction.

How Entity Type Shapes Your Asset vs. Stock Decision
Entity type can be the single biggest variable in the after-tax outcome of a dental practice sale. The same headline price can produce very different results depending on how the practice is organized. Many general M&A overviews skip this topic, yet it often matters most for dentists.
S-Corporation
In an asset sale, gain usually flows through to shareholders and is taxed once at the individual level, which can be a meaningful advantage over C-corporations. However, depreciation recapture, unrealized receivables, and inventory can still create ordinary income even in a pass-through structure. In a stock sale, shareholders pay capital gains tax on the stock, and the entity itself does not pay a separate tax on the gain.
A buyer of S-corporation stock can sometimes elect IRC Section 338(h)(10). That election treats the stock sale as an asset sale for tax purposes, giving the buyer a stepped-up basis while the seller remains taxed at the individual level. Basis tracking matters because an S-corporation shareholder’s stock basis increases with pass-through income over the years, which can reduce taxable gain on a stock sale.
C-Corporation
C-corporations can face a classic double-tax outcome in an asset sale. The entity pays corporate-level tax on the gain at the current flat 21% federal rate. Shareholders then pay tax again on the liquidating distribution at capital gains rates, plus the potential 3.8% NIIT.
The combined federal burden can approach 45% of the gain in an asset deal, compared with roughly 23.8% in a stock sale. Many C-corporation owners therefore explore stock sales or consider an S election well before a planned sale. The built-in gains (BIG) tax under IRC Section 1374 can impose a corporate-level tax on appreciated assets sold within 5 years of converting from C to S status, so timing an S election requires careful planning.
LLC
Taxation of an LLC depends on its election. A single-member LLC disregarded for tax purposes is treated like a sole proprietorship, so every sale functions as an asset sale. A multi-member LLC taxed as a partnership allocates gain among members according to the operating agreement, and IRC Section 751 “hot asset” rules can create ordinary income on inventory and receivables even when members sell their interests. An LLC that has elected S-corporation tax treatment follows the S-corporation rules described above.
Sole Proprietorship
A sole proprietor has no stock to sell, so every transfer functions as an asset sale and all gain appears on the owner’s individual return. Asset allocation directly determines the character of each slice, with goodwill at capital gains rates and equipment recapture at ordinary income rates. There is only one layer of tax, but there is also no stock-sale alternative.
Entity type should be reviewed with a CPA well before going to market. Some structural changes, such as an S election, involve waiting periods and built-in gains rules that can take years to work through. For a step-by-step overview of the full sale process, see How to Sell Your Dental Practice: A Step-by-Step Guide.
The Net-Proceeds Reality: Comparing a $1.5M Asset Offer and a $1.5M Stock Offer
What you keep depends on after-tax proceeds, not the headline number. Those proceeds depend on allocation, entity type, basis, and the tax character of each slice of gain. Two offers at the same price can produce very different after-tax outcomes based on how much goes to goodwill, equipment, and non-compete agreements.
Consider a qualitative example. One offer might place a large portion of value in goodwill, which receives capital gains treatment at the 20% rate discussed earlier. Another offer might assign a similar portion to equipment recapture and a non-compete, which can be taxed at ordinary income rates that can reach 37% federally. The 17-point gap between those rates becomes very meaningful when applied to a large allocation.
This difference is why a diligence-grade, CPA-led valuation and multi-year cash-flow modeling can matter before you accept any structure. The seller benefits from comparing real after-tax proceeds instead of headline prices. Modeling should occur with the seller’s own advisors, not only with the buyer’s spreadsheet.

Dental-Specific Operational Details in Each Structure
Dental practice transitions involve operational details that can affect timing, cost, and patient experience. These details should be mapped before the LOI is signed so the chosen structure aligns with practical realities.
- Re-credentialing: Insurance panels and Medicare or Medicaid credentials usually must be re-established when the entity changes. Credentialing after a practice acquisition can take 90–120 days once paperwork is complete, and some carriers take longer. A credentialing gap in a busy practice can mean tens of thousands of dollars in deferred or reduced revenue. Buyers can reduce this risk by preparing credentialing applications well before closing.
- Patient records: Transfer and retention rules vary by state dental board. California, for example, requires adult patient records to be kept for at least 7 years from the date of last service. HIPAA compliance must continue through the transition, and patients retain access rights during ownership changes.
- Lease assignment: Most dental leases require landlord consent before assignment. An asset sale can trigger assignment requirements, while a stock sale may preserve the existing lease because the entity does not change. Some leases include change-of-control provisions that operate similarly to assignment clauses. Counsel should review lease terms before the LOI is signed.
- State dental board ownership rules: Most U.S. states enforce some version of the corporate-practice-of-dentistry doctrine, which requires a licensed dentist to own and control the clinical practice. In some states, this framework can limit whether a stock sale to a non-dentist buyer is allowed. DSO structures often work through management services organizations instead of direct clinical ownership. State rules vary and continue to evolve, with states such as California and Colorado updating their frameworks.
How to Decide Between an Asset Sale and a Stock Sale: A Negotiation Playbook
Sellers who treat structure as a negotiated term can often improve their outcome. The steps below outline a practical order of operations for that discussion.
- Confirm entity type and basis with your CPA. Clarify whether you operate as an S-corp, C-corp, LLC, or sole proprietorship, and understand your stock or asset basis before speaking with buyers.
- Obtain a defensible valuation. A diligence-grade, CPA-led valuation anchors the discussion around your EBITDA and reduces the risk of a re-trade when buyers review the numbers.
- Model after-tax proceeds under each structure. Compare a stock sale, an asset sale with a favorable allocation, and, when relevant, a Section 338(h)(10) election. The comparison should focus on after-tax proceeds rather than headline prices.
- Negotiate allocation and structure in the LOI. The allocation exhibit in the purchase agreement becomes a binding tax agreement. Address it in the LOI instead of leaving it for post-closing discussions.
- Confirm operational mechanics. Map re-credentialing timelines, patient record obligations, lease assignment requirements, and state board rules before you sign.
- Run a competitive process. When multiple qualified buyers participate, structure becomes one of several negotiated terms instead of a fixed condition. Competition can be a seller’s strongest tool.
- Close with quality-of-earnings support. The agreed value should withstand diligence. A well-prepared seller reduces the chance that the deal will be re-traded near closing.
Some terms merit firm pushback, such as an allocation that concentrates too much value in ordinary income categories, an oversized non-compete, or a punitive earnout. If a buyer refuses a defensible allocation or insists on shifting a disproportionate tax burden to you without a price adjustment, that stance can signal how the post-close relationship may feel, and walking away can sometimes be the better choice.

Why McLerran & Associates Is a Focused Sell-Side Partner for This Choice
McLerran & Associates is a dental-specific sell-side M&A advisory and brokerage firm that regularly runs both private-buyer and DSO or private-equity processes. That dual-path experience matters for the asset-versus-stock decision because structure and path usually move together. A doctor-to-doctor buyer and a DSO buyer often approach structure differently, and a seller who has seen only one path may not know which deal truly serves them better.
Because McLerran works both paths, the team can prepare a side-by-side valuation that shows a practice’s value in the private-buyer market and in the DSO market. The owner can then choose structure and path with more complete information instead of relying on guesswork. Each engagement starts with a CPA-led, diligence-grade EBITDA analysis, so the numbers are designed to hold up when buyers review them and the deal is less likely to be re-traded late in the process.
McLerran typically runs a structured, auction-style bid process over 45–60 days, generating multiple offers from a vetted pool of qualified buyers. Poorly performing buyers are removed from future processes. That level of competition helps turn structure into a negotiated term instead of a buyer’s dictate.
The firm’s history includes thousands of completed practice sales and significant closed transaction volume. McLerran represents only sellers, so the client is always the practice owner.
For owners still deciding whether to sell, the McLerran M&A Summit (October 29–30, 2026) offers an educational setting with 4 CE credits and a complimentary practice valuation.

Frequently Asked Questions
Is a Stock Sale Better Than an Asset Sale for a Dental Practice?
The better structure depends on your entity type and the specific allocation. For many sellers, a stock sale can be attractive because the entire gain may qualify for long-term capital gains treatment, which avoids ordinary income on depreciation recapture and non-compete payments. Buyers usually prefer asset deals for the stepped-up basis, so a seller who requests a stock sale often needs to accept a price adjustment. For C-corporation sellers, avoiding double taxation in an asset sale can make a stock sale especially valuable. For S-corporation sellers, the gap between structures can be narrower because tax applies once at the shareholder level in either case. The right answer is practice-specific and usually requires modeling both scenarios with a CPA.
Is There a Standard Allocation Rule in Dental Practice Sales?
Allocation of purchase price in a dental practice sale depends on the facts of each transaction, including valuation, asset mix, and negotiation between buyer and seller. No universal allocation rule fits every deal. Actual after-tax outcomes depend on allocation, entity type, and basis. If a buyer or advisor mentions a specific allocation rule, ask them to describe the exact mechanism and how it applies to your practice.
What Is Goodwill Allocation in a Dental Practice Sale?
Goodwill represents the residual value of a dental practice after all other identifiable assets are valued. It reflects reputation, patient relationships, location, and going-concern value. In many dental practice sales, goodwill makes up the largest portion of the purchase price. For tax purposes, goodwill is a Class VII asset under IRC Section 1060, and gain allocated to goodwill usually receives long-term capital gains treatment rather than ordinary income treatment.
Sellers often benefit when more value is allocated to goodwill, while buyers may prefer more value in equipment and non-competes that they can deduct faster. The allocation is negotiated and must be reported consistently by both parties on IRS Form 8594.
Do I Have to Keep Working After I Sell?
In most DSO or private-equity affiliation deals, sellers continue working for several years under a post-close employment or services agreement. The exact length and terms vary by buyer and structure. In a private doctor-to-doctor walk-away sale, the seller often works back only a few weeks before exiting. Partnership or vest-out structures usually involve a longer, planned transition period. The post-close working arrangement is a negotiated term, and its length, compensation, and clinical autonomy provisions should be reviewed carefully.
Is Now a Good Time to Sell a Dental Practice?
Demand for strong, Class A dental practices remains healthy, and valuations for well-run practices sit near historically high levels in many markets. Conditions still vary by specialty, geography, and practice profile. The right time to sell depends on your practice’s financial position, your personal goals, and whether you have completed the preparation work such as entity review, valuation, and process planning.
McLerran can provide a candid view of where your practice stands today. If the practice is not yet ready, the firm can update your valuation at no charge a year later rather than encouraging a sale before the timing fits your plans.
Conclusion: Using Structure as a Negotiation Tool
The asset sale versus stock sale decision functions as a negotiation lever that can shape how much you keep after tax. A seller who understands allocation, entity type, and net-proceeds math can often preserve more of what they have built. Helpful next steps include reviewing entity structure and basis with a CPA, obtaining a defensible valuation, modeling after-tax proceeds under each structure, and running a competitive process with an experienced sell-side advisor.
McLerran & Associates works both private-buyer and DSO paths in roughly equal measure, which allows the team to provide a genuine side-by-side comparison that single-lane brokers may not offer. That comparison can form the basis for an informed decision about structure and path.
