Dental Practice Valuation and Sale: What Determines the Price and How the Tax Works

Selling a dental practice is one of the largest financial transactions most dentists will ever complete, and the tax consequences of the sale depend almost entirely on decisions made before the closing date. The total price is just the starting point. What matters for both the buyer and the seller is how that price gets divided among the assets included in the deal, because every dollar allocated to equipment is taxed differently than a dollar allocated to goodwill, which is taxed differently than a dollar allocated to a covenant not to compete. The IRS requires both sides to report the allocation on Form 8594 under IRC 1060, and an inconsistent filing between buyer and seller is an audit trigger. On top of the allocation, the distinction between personal goodwill and practice goodwill can shift hundreds of thousands of dollars from ordinary income (or double taxation in a C-corp) to long-term capital gain. This guide covers the full process: how dental practices are valued, what’s included in the sale, how the IRC 1060 allocation works, the personal goodwill strategy, the seller’s and buyer’s tax treatment on each component, installment sale deferral, and the transition mechanics that hold the deal together after closing.

How are dental practices valued?

Two primary methods drive most dental practice valuations: a percentage of gross collections and a multiple of seller’s discretionary earnings. Most practice transitions involve both, and they serve as cross-checks on each other. The right valuation depends on the practice’s size, location, payer mix, specialty, and the degree to which the practice depends on the selling dentist personally.

The percentage-of-collections method values the practice as a percentage of its annual gross collections (total production collected, not billed). For a general dentistry practice in a mid-size metro area, the typical range is 65% to 85% of trailing twelve-month collections. Practices heavily dependent on a single provider (the selling dentist personally produces 95% of the revenue) tend toward the lower end, 50% to 70%, because the buyer takes on significant patient attrition risk. Established multi-provider practices with associate dentists already seeing patients, and specialty practices (orthodontics, oral surgery, periodontics) with strong referral networks, tend toward the higher end and sometimes exceed 85%.

The percentage-of-collections method is simple and widely understood in the dental community, but it has a significant limitation: it ignores profitability. A practice collecting $1.2 million per year with 40% overhead is a fundamentally different investment than a practice collecting $1.2 million with 70% overhead, even though the collections-based valuation treats them identically.

The seller’s discretionary earnings (SDE) method solves this problem. SDE starts with the practice’s net income and adds back the owner’s compensation, depreciation, amortization, interest expense, non-recurring expenses (a one-time office renovation, a litigation settlement), and personal expenses the owner has run through the practice (the owner’s car, phone, CE courses, and similar items). The result is the total economic benefit the practice generates for a single owner-operator.

A typical dental practice sells for 1.5x to 3.5x SDE. The multiple varies with the same factors that drive the collections percentage: practice size, location, patient demographics, payer mix, the mix between insurance and fee-for-service, the presence of associate dentists, the age and condition of the equipment, and the selling dentist’s willingness to stay for a meaningful transition period. A practice in a growing suburban area with a strong hygiene recall system, a diversified payer mix, modern equipment, and an associate already handling 30% of production will command a multiple near the top of the range. A solo-provider practice in a declining market with aging equipment and a fee schedule dominated by low-reimbursement PPO plans will sit near the bottom.

The two methods should produce valuations in a similar range. If they diverge significantly, something is off. A high collections-based value paired with a low SDE multiple usually means the practice has a revenue problem (high collections but low profitability, often from excessive overhead or a weak fee schedule). A high SDE multiple paired with a modest collections-based value usually means the practice is unusually efficient or has a specialty mix that generates higher margins per dollar of production. Any significant divergence between the two methods warrants a closer look at the practice’s financials before either side commits to a price.

What’s included in the sale?

A dental practice sale typically includes everything the buyer needs to walk in on Monday morning and start seeing patients. The assets fall into three categories: tangible assets, intangible assets, and (sometimes) real estate.

Tangible assets include the dental chairs, operatory equipment, sterilizers, X-ray units, intraoral cameras, CAD/CAM systems, handpieces, instruments, office furniture, computers, practice management software licenses, signage, and the supplies inventory on hand at closing. Leasehold improvements (the buildout of the operatory rooms, cabinetry, plumbing, and electrical work specific to a dental office) are tangible assets tied to the lease. The buyer typically gets an equipment appraisal from a dental-specific appraiser, which establishes the fair market value of the tangible assets for the purchase price allocation. Dental equipment depreciates quickly in terms of market value (a 10-year-old panoramic X-ray unit has very different market value than a 2-year-old CBCT scanner), so the appraised values are often well below what the seller originally paid.

Intangible assets are where most of the value sits. The patient records and charts are the cornerstone. Technically, patient records belong to the patients (the dentist is the custodian, not the owner), so what the buyer is actually acquiring is the right to serve as the custodian of those records and the right to contact those patients to continue their care. That right has real economic value because it represents the practice’s active patient base, the recall system, and the ongoing revenue stream those patients represent. Beyond patient records, the intangible assets include the practice name, phone number, website and online presence, review profiles, referral relationships, practice goodwill, personal goodwill (discussed in detail below), and a covenant not to compete signed by the seller.

Real estate is sometimes part of the deal. If the selling dentist owns the building or condo unit where the practice operates, the real estate can be sold to the buyer as part of the transaction or retained by the seller and leased to the buyer under a new commercial lease. The decision depends on the buyer’s financing, the real estate’s value, and whether the seller wants to maintain a passive income stream from rent after the practice sale closes. When the real estate is sold separately, it’s a distinct transaction with its own tax treatment (Section 1250 recapture on the building, capital gain on the land), and it should not be lumped into the practice purchase price allocation.

How does the IRC 1060 allocation work for a dental practice sale?

Both the buyer and the seller must allocate the total purchase price across seven classes of assets using the residual method prescribed by IRC 1060. This is the same seven-class hierarchy that applies to any business asset sale, but dental practices have specific features that make the allocation especially important.

The seven classes, in the dental context, work as follows.

• Class I: Cash and cash equivalents. Usually zero in a dental practice sale.
• Class II: Actively traded personal property, CDs, and similar items. Rarely present.
• Class III: Accounts receivable. If the buyer assumes the seller’s AR (uncommon, but it happens when the practice has a large insurance receivable balance), the fair market value goes here. Most dental practice sales exclude AR, with the seller collecting outstanding receivables after closing.
• Class IV: Inventory (dental supplies, lab materials, disposables on hand). Valued at fair market value, which is usually close to cost.
• Class V: Tangible personal property (all the equipment, furniture, fixtures, instruments, leasehold improvements). Valued at fair market value based on the equipment appraisal.
• Class VI: Section 197 intangibles other than goodwill and going concern value. This includes patient records/charts (the custodianship right), the practice name and phone number, the practice’s website and online presence, covenants not to compete, workforce in place, and referral network value.
• Class VII: Goodwill and going concern value. This is the residual, the amount left over after all assets in Classes I through VI have been valued.

The allocation is critically important in dental practice sales because the asset classes carry dramatically different tax rates for the seller. Equipment in Class V triggers depreciation recapture under IRC 1245 (ordinary income, up to 37% federal plus state). Supplies in Class IV are ordinary income. The covenant not to compete in Class VI is ordinary income. But goodwill in Class VII is long-term capital gain (0%, 15%, or 20% federal, plus the 3.8% net investment income tax if the seller’s modified adjusted gross income exceeds the threshold). For a seller in the top bracket, the difference between ordinary income and long-term capital gain is roughly 17 percentage points on the federal rate alone.

The buyer has the opposite preference for some categories. Dollars in Class V (equipment) can be depreciated over 5-7 years under MACRS, with the option to expense the full amount in year one using Section 179 or bonus depreciation. Dollars in Class VI and VII (Section 197 intangibles, including goodwill) must be amortized over 15 years regardless of the covenant’s contractual term or the useful life of the patient records. The buyer would generally prefer more dollars in equipment (faster write-off) and fewer in goodwill (slower write-off). The seller prefers the opposite: more in goodwill (capital gain) and less in equipment (ordinary income recapture).

This tension is resolved through negotiation, and the purchase agreement should include an allocation schedule as an exhibit. Both parties report the agreed allocation on Form 8594 attached to their tax returns for the year of sale. If they file inconsistent allocations, the IRS will likely examine both returns.

What is personal goodwill and why does it matter in a dental practice sale?

Personal goodwill is the single most important tax planning concept in dental practice sales, particularly for dentists who operate through C-corporations. It represents the value of the selling dentist’s personal patient relationships, professional reputation, clinical skills, and referral network, as distinguished from the practice entity’s own goodwill.

Practice goodwill (sometimes called enterprise goodwill or entity goodwill) is the value attributable to the practice as an organization: its systems, location, trained staff, brand recognition, operational processes, and the recurring revenue streams that would continue even if the selling dentist left tomorrow. If the practice has a strong hygiene department that generates $400,000 a year in recall visits, and those patients return because of the practice’s recall system and the hygienists they know (not because of the selling dentist), that revenue stream is practice goodwill.

Personal goodwill is different. It belongs to the individual dentist, not to the entity. It’s the value that would walk out the door if the dentist left. If a patient chose the practice because Dr. Smith’s neighbor referred them to Dr. Smith specifically, and they’d follow Dr. Smith to a new location, that relationship is personal goodwill.

The distinction matters because of how the two types of goodwill are taxed in different entity structures. If the practice is a C-corporation and the entity sells its assets (including goodwill), the corporation pays corporate income tax on the gain, and then the shareholder pays a second layer of tax when the after-tax proceeds are distributed (as a liquidating distribution or dividend). This double taxation can consume 40% to 50% of the goodwill proceeds.

But personal goodwill belongs to the dentist individually, not to the corporation. If the dentist never transferred personal goodwill to the corporation (no employment agreement assigning it, no non-compete between the dentist and the entity), the dentist can sell personal goodwill directly to the buyer in a separate transaction. The proceeds go to the dentist personally, bypass the corporation entirely, and are taxed as long-term capital gain at 0%, 15%, or 20% plus the 3.8% NIIT. The tax savings can be substantial.

The IRS has challenged personal goodwill claims, particularly when the dentist has an employment agreement with the entity, a non-compete agreement with the entity, or any contractual arrangement that arguably transferred the dentist’s personal relationships to the entity. The key to sustaining a personal goodwill claim is the absence of a contractual obligation that ties the dentist’s relationships to the entity. If the dentist is an at-will employee (or, better, has no employment agreement at all), has no non-compete with the entity, and can credibly demonstrate that patients came for the dentist personally rather than for the practice brand, the personal goodwill claim is on stronger footing. Case law (including Martin Ice Cream Co. v. Commissioner and Muskat v. United States) supports the concept, but the factual analysis is specific to each practice.

For dentists operating through S-corporations, LLCs, or sole proprietorships, the personal goodwill distinction has less tax impact because there’s no corporate-level tax to avoid. The goodwill flows through to the individual regardless. However, separating personal goodwill can still matter for state tax purposes in states that tax business income differently from personal capital gains, and it matters for the 3.8% NIIT calculation (personal goodwill sold by an individual who is not materially participating in the practice at the time of sale may be subject to the NIIT, while goodwill sold through an S-corp where the shareholder materially participates may not be).

How is the seller taxed on each component of the sale?

The seller’s tax treatment varies by asset class, and most dental practice sales produce a mix of ordinary income, recapture income, and long-term capital gain on the same transaction.

Dental supplies and inventory (Class IV) produce ordinary income. The gain is the difference between the amount allocated to supplies and the seller’s cost basis. Since supplies are usually valued at or near cost, the gain is typically small.

Equipment, furniture, fixtures, and instruments (Class V) produce a two-layer result. Under IRC 1245, the gain is ordinary income to the extent of all depreciation previously claimed on the asset. This is depreciation recapture. If a dental chair cost $15,000 and the seller has claimed $12,000 in depreciation (adjusted basis of $3,000), and the allocation assigns $8,000 to that chair, the $5,000 gain is all ordinary income because it falls entirely within the $12,000 of prior depreciation. Any gain above the original cost would be capital gain, but dental equipment rarely appreciates above its original purchase price.

Covenant not to compete (Class VI) is ordinary income to the seller, period. There’s no capital gain treatment. The covenant represents compensation the buyer is paying the seller for agreeing not to open a competing practice. For the seller, every dollar allocated here is taxed at the ordinary income rate. For the buyer, the covenant is a Section 197 intangible amortized over 15 years, regardless of the covenant’s actual contractual term (even if the covenant runs for only three years, the amortization period is 15).

Patient records, practice name, and other identifiable intangibles (Class VI) follow the Section 197 recapture rules under IRC 197(f)(7). Gain is ordinary income to the extent of previously claimed amortization. Any gain above the original amortized basis is treated as long-term capital gain (Section 1231 gain for assets held more than one year).

Practice goodwill (Class VII) is long-term capital gain. Federal rates are 0%, 15%, or 20% depending on the seller’s taxable income, plus the 3.8% net investment income tax under IRC 1411 if the seller’s MAGI exceeds the threshold ($250,000 for married filing jointly, $200,000 for single filers). Since goodwill typically has a zero cost basis for a practice the seller built from scratch (as opposed to one the seller purchased), the entire amount allocated to goodwill is gain.

Personal goodwill (if properly separated from the entity) is long-term capital gain at the same rates. The seller reports it on Schedule D, not through the entity’s return.

How is the buyer taxed, and what can the buyer deduct?

The buyer’s tax treatment is the mirror image of the seller’s: the purchase price allocation determines when and how the buyer recovers each dollar spent.

Supplies (Class IV) are deductible as cost of goods sold when consumed. The buyer uses or disposes of the acquired supplies in the ordinary course of practice operations, and the cost flows through as an expense.

Equipment, furniture, fixtures, and instruments (Class V) are depreciable under MACRS. Most dental equipment falls into the 5-year or 7-year property class. The buyer can elect to expense the full cost in year one using Section 179 (subject to the annual dollar limit, which is $1,250,000 for 2025), or claim bonus depreciation if available. For a buyer financing the practice with a practice acquisition loan, the ability to deduct the full equipment cost in year one while paying for it over five to ten years creates a significant cash flow advantage in the early years of ownership.

Covenant not to compete (Class VI) is a Section 197 intangible. The buyer amortizes it over 15 years, straight-line. This is true even if the covenant only runs for three years. The buyer cannot accelerate the amortization when the covenant expires. The mismatch between the contractual term and the amortization period is a frequent point of frustration for buyers, but the statute is clear: all Section 197 intangibles share the same 15-year recovery period.

Patient records, practice name, and other identifiable intangibles (Class VI) are also Section 197 intangibles, amortized over 15 years.

Practice goodwill (Class VII) is a Section 197 intangible, amortized over 15 years. For a buyer paying $500,000 for goodwill, the annual amortization deduction is $33,333. At a 37% marginal rate, that’s roughly $12,333 per year in tax savings, compounding over 15 years.

Acquisition financing. The buyer typically finances the purchase with a practice acquisition loan from a bank or a specialty dental lender. The interest on the loan is deductible as a business expense. Combined with the depreciation and amortization deductions, the tax benefits of the acquisition often cover a meaningful portion of the annual debt service in the early years.

Can a seller use an installment sale to defer the tax?

Yes. If the buyer pays part of the purchase price over time (a seller note, earnout, or any deferred payment arrangement), the seller can report the capital gain portion under the installment method of IRC 453. The seller recognizes capital gain proportionally as each payment is received, rather than recognizing the full gain in the year of sale. This is particularly useful when the sale price is large enough to push the seller into the top capital gains bracket (20% rate) or trigger the 3.8% NIIT.

The installment method only applies to the capital gain components (goodwill, patient records if treated as capital gain, and any equipment gain above recapture). The ordinary income components are recognized in full in the year of sale. Depreciation recapture under IRC 1245 is recognized in year one regardless of when the cash arrives. The covenant not to compete income is recognized when earned (typically in year one, unless the covenant payments are explicitly structured over the covenant’s term).

For a practice sale with a large goodwill component and a seller note, the installment method can spread several hundred thousand dollars of capital gain over five or more years, keeping the seller’s marginal rate lower in each year. The tradeoff is that the seller carries credit risk on the note: if the buyer defaults or the practice underperforms, the seller may not collect the full amount. The seller should require adequate security (a lien on the practice assets, personal guarantee from the buyer) and consult with counsel on the note’s terms.

There is one additional wrinkle. If the sale price exceeds $5 million, the installment obligation may trigger the special tax on deferred amounts under IRC 453A, which charges interest on the deferred tax liability. Most dental practice sales fall below this threshold, but multi-location practices or practices with significant real estate could exceed it.

What happens during the transition period?

The transition period is the bridge between the old dentist and the new one. It’s what makes the goodwill the buyer paid for actually stick. Without a smooth transition, patients leave, staff quits, and the buyer’s investment erodes. Both sides have strong incentives to get this right.

The selling dentist typically stays for a transition period ranging from 30 days to 180 days (and sometimes longer for larger practices or specialty practices with complex cases in progress). During this period, the seller introduces the buyer to patients, staff, and referral sources. The seller may continue to treat patients on a reduced schedule while the buyer ramps up. The goal is for patients to develop a relationship with the buyer before the seller departs.

The compensation arrangement during the transition can be structured in two ways. The seller can serve as an independent contractor, receiving a consulting fee reported on Form 1099-NEC. The fee is deductible to the buyer as a business expense and is self-employment income to the seller (subject to self-employment tax). Alternatively, the seller can be a W-2 employee of the buyer’s entity during the transition. The employment arrangement triggers payroll taxes for both sides but avoids self-employment tax for the seller. The choice depends on the parties’ preferences, the length of the transition, and whether the seller wants to receive benefits (health insurance, for example) during the transition period.

The covenant not to compete is the other critical transition element. A typical dental practice covenant covers 3 to 5 years and a radius of 10 to 25 miles. The scope must be reasonable to be enforceable under state law. An overly broad covenant (10 years, 100 miles) may be struck down entirely by a court, or reformed to a reasonable scope, depending on the state. For tax purposes, the buyer claims the covenant as a Section 197 intangible amortized over 15 years. The IRS has accepted reasonable covenant values when they are negotiated at arm’s length and documented in the purchase agreement. A covenant with no consideration (the seller signed it for free as part of the sale) is harder for the buyer to claim as a separate intangible, because the IRS may argue the covenant’s value is already embedded in the goodwill.

Staff retention is a practical concern that doesn’t show up on the Form 8594 but affects the economics of the deal. The buyer typically assumes no obligation to retain the seller’s staff (they are employees at will), but losing experienced hygienists, assistants, and front-desk staff during the transition can drive patients away. Many purchase agreements include a provision requiring the seller to encourage staff to stay through the transition. Some buyers offer retention bonuses to key staff members as an incentive.

What should I do next?

If you’re thinking about selling your dental practice in the next one to five years, the time to start planning is now, not six months before closing. The personal goodwill strategy requires that you have no employment agreement or non-compete with your own entity, and undoing those arrangements after you’ve started marketing the practice looks aggressive to the IRS. The entity structure of your practice affects the sale mechanics directly, especially if you’re operating through a C-corporation and want to use the personal goodwill bypass. The purchase price allocation is negotiated with the buyer, and understanding which asset classes help you (goodwill) and which hurt you (covenant not to compete, equipment recapture) gives you leverage in that negotiation.

Here are the next steps.

• Dental practice entity structure: LLC, S-corp, or partnership? covers how the entity structure you’re operating under today affects the sale mechanics, particularly the personal goodwill strategy and whether you face single or double taxation on the proceeds.
• Dental practice tax deductions: equipment, supplies, and more covers the buyer’s ongoing deduction picture after the acquisition closes, including Section 179, bonus depreciation, and the amortization of intangibles.
• Selling a franchise: tax treatment of transfers, resales, and goodwill allocation walks through a parallel sale and IRC 1060 allocation analysis for franchise businesses, with the same buyer-vs-seller tension on the allocation.
• Law firm succession planning: buy-sell agreements and valuation covers similar valuation and sale mechanics for law firms, including the personal goodwill analysis in the professional services context.
• Dental service organizations (DSOs) covers the DSO transaction structure, where selling to a PE-backed DSO produces a different deal structure, valuation multiple, and tax treatment than a traditional practice-to-practice sale.
