Capital Gains Tax When You Sell Your Dental Practice: What You Actually Keep in 2026

The first question is almost never about the offer.

It is about the wire. How much of this actually reaches my account?

I have had that conversation over dinner more times than I can count, and it arrives roughly ninety seconds after an owner reads me the headline number off a term sheet he has already photographed twice.

They know what the practice is worth. They have no idea what they keep.

Here is the uncomfortable half of the answer. Much of it gets settled in paperwork drafted weeks after everybody shook hands on the price.

Key takeaways

• There is no single rate on a practice sale. The IRS treats it as a sale of individual assets, and gain or loss on each one is figured separately. Some is capital gain. Some is ordinary income.
• The split of the price decides the character of every dollar. Goodwill, operatory equipment, a covenant not to compete and post-closing pay are each treated differently, and both sides report that split to the IRS.
• Timing is a separate question from rate. Depreciation recapture must be reported in the year of sale even when you are paid over five years, so the bill and the cash can arrive in different years.
• Geography can outweigh every federal lever. Eight states impose no individual income tax whatsoever, while the steepest top marginal rate in the country reaches 13.3 percent.
• The items with genuine leverage need years, not weeks. Entity choice, basis records and supporting documentation all demand lead time. Sign a letter of intent and most of that list closes behind you.

How is the sale of a dental practice taxed? Not at one rate. The price is divided across what is being sold, and each slice carries its own treatment.

Goodwill is generally capital gain. Equipment usually throws off ordinary income.

Your entity, your state and the shape of the deal decide the remainder.

One thing before we go further. This article is general information, not tax advice. It knows nothing about your entity, your basis, your residency or your filing status.

Every figure below has to be modelled on your own numbers by a CPA who has done dental transactions. I will repeat that in the middle and once more at the end, and I mean it each time.

Why the price and the proceeds are two different numbers

Owners picture a sale as one number with a haircut applied. That model causes most of the disappointment I watch land.

The real sequence runs five steps, and only the first ever comes up over dinner.

A price is agreed, then divided across what is genuinely changing hands, and that division hands every slice a tax character which in turn fixes a rate ceiling, while the deal’s structure quietly decides which calendar year each piece falls due.

Move any of those middle steps and the wire changes while the headline sits exactly where it was.

Which reframes the whole exercise. Two dentists can sell mirror-image practices for identical prices in the same month and bank materially different sums.

None of it is exotic. The IRS puts it flatly: selling a practice is usually not the sale of one thing, all the assets are sold, and gain or loss on each asset is figured separately.

Worth noting the scale. ADA Health Policy Institute data has average net income for a general practitioner sitting in the low $200,000s, so a sale is frequently worth more than a decade of take-home pay.

What is the difference between capital gains and ordinary income?

What makes a dollar capital gain instead of ordinary income? Capital gain treatment generally applies to profit on a capital asset held more than one year, taxed under a separate and lower rate schedule. Ordinary income rides your regular marginal bracket and can attract employment taxes on top of that.

This is the largest single lever in the transaction, and it gets decided asset by asset rather than all at once.

Begin with the holding period, the cleanest rule in the whole code. Hold something more than a year before disposing of it and the gain is long-term.

A year or less and it is short-term.

For a dentist who built a practice across two decades, that test is nearly always satisfied. Nearly.

A panoramic unit bought fourteen months before closing is a different conversation from the chair installed in 2009.

Long-term gain runs on its own schedule with three steps: 0 percent, 15 percent and 20 percent, keyed to taxable income. A separate maximum of 25 percent applies to unrecaptured gain on real property, which bites if you own your building.

Now a deliberate omission, and I would rather explain it than quietly skip past it.

You will not find the dollar thresholds where those steps change anywhere on this page. They shift annually, and the IRS publishes them one tax year at a time.

A stale bracket printed here would be worse than none. Ask your accountant for the current figures, then ask a second time in the year you actually close.

Ordinary income behaves differently and worse, because it stacks on whatever else you earned that year at your marginal rate, and where a payment has been dressed as compensation for services it may drag payroll or self-employment tax along behind it.

One more term before the next section. Gain is not the payment.

Gain is the payment minus your adjusted basis in whatever you sold.

Basis is broadly what you paid, adjusted since. Depreciation you claimed reduces it.

That single sentence explains why so many sellers get ambushed by their own operatory.

Goodwill you built yourself typically carries little or no basis, so nearly the whole allocation to it is gain. Happily, it is also the best-treated gain in the deal.

Where is the tax rate actually decided?

What is purchase price allocation and why does it set my rate? It is the division of the total price across categories of assets sold. That division fixes the tax character of each slice, and buyer and seller both report it to the IRS on Form 8594 under the residual method, so it must be agreed rather than assumed.

Why a buyer pushes for what it pushes for, and how the structure decision itself gets made, belong elsewhere. We work through the buyer’s arithmetic in our guide to an asset sale versus a stock sale.

This piece cares only about your side: what each slice does to your rate, and when the bill lands.

Four categories carry almost the whole dental deal.

What the price is paid for	Usual character to the seller	Rate exposure	When the tax typically lands
Goodwill and going-concern value (Class VII)	Capital gain, where the holding period is met	The long-term capital gain schedule	Spread across payments where the installment method applies
Equipment, cabinetry, imaging (Class V)	Ordinary up to depreciation already claimed, capital beyond it	Your regular marginal bracket on the recaptured slice	Recapture reported in full in the year of sale
Covenant not to compete (Class VI)	Ordinary income	Your regular marginal bracket	Broadly as payments are made
Consulting or employment pay (outside the allocation)	Ordinary income	Marginal bracket, plus payroll or self-employment tax	As earned, after closing

Read that as a menu and the incentive is obvious. A dollar parked in the goodwill row and a dollar parked in the covenant row cost the buyer roughly the same and cost you very different amounts.

Here is arithmetic almost nobody runs. On a $4.2 million price, the distance between an allocation putting 85 percent on goodwill and one putting 70 percent there is $630,000 of consideration changing tax character.

The price never moved. Only the character did.

The Florida Dental Association tells its own members the same thing in blunter language: the more of a price loaded onto hard assets, the higher the seller’s tax cost, and where each line falls is negotiated.

The equipment trap

Now the part that ambushes careful people, precisely because they were careful.

Gain on depreciable property is ordinary income to the extent of depreciation allowed or allowable. Every accelerated write-off you claimed on the CBCT, the chairs, the intraoral scanner and the cabinetry returns as ordinary income the day you sell.

You already banked the deduction. This is the settling up.

Picture a practice that has expensed nearly all its clinical equipment across ten years of aggressive but perfectly legitimate write-offs, leaving an adjusted basis close to nothing, and then allocate $400,000 of the price there.

Roughly $400,000 becomes ordinary income.

The owner reads “$400,000 for my equipment” as a neutral line item, roughly equivalent to being handed back the worth of things he already owns.

It is one of the costliest rows on the page.

Which is exactly why allocation belongs in the letter of intent, while a buyer still wants your signature, rather than at the closing table once it has it.

Does my entity type change what I keep?

Does entity type change the tax on a practice sale? Substantially. A sole proprietorship, an S corporation and an LLC or PLLC taxed as a partnership generally yield one layer of tax on the gain.

A C corporation can be taxed at entity level and taxed again when proceeds reach the owner.

The awkward truth is that this got decided years ago, often by an accountant you no longer use, for reasons unrelated to any sale.

Most established general practices sit inside an S corporation or a PLLC, producing one layer that flows onto your personal return. Ordinary case, fine outcome.

The C corporation is the outlier, and it costs real money. Why, and what a recent conversion from C to S does to the arithmetic, sits in the asset sale versus stock sale piece.

Members of an LLC or PLLC carry a wrinkle worth flagging: gain on a sale of a partnership interest is generally capital, but the rules covering unrealized receivables and inventory items convert part of it into ordinary income.

For a practice carrying heavy uncollected production, that is not hypothetical.

So what can you still do? Less than you would like, more than nothing.

An entity review three years ahead of a sale is genuine planning. The same review three weeks before closing is a conversation about regret.

What is the difference between personal and practice goodwill?

What is personal goodwill in a dental practice sale? It is the share of goodwill attributable to the individual dentist’s own reputation, relationships and skill rather than to the practice entity. Where it exists and is properly documented, that share may be treated as an asset sold by the dentist personally.

Easily the most under-covered idea in dental transaction tax. Also the one most often oversold, so let me handle it carefully.

The intuition is sound. Patients follow people.

A dentist who has treated three generations of one family built something arguably hers, not her professional corporation’s.

It matters most inside a C corporation, where consideration genuinely paid to the dentist for a personally held asset may sidestep the entity-level layer altogether rather than getting taxed on the way out.

Now the caution, and please read it twice. Whether personal goodwill exists in any given transaction is intensely fact-specific and frequently contested.

The factors examined are unglamorous and almost entirely about filing cabinets, since what decides the argument is usually a paragraph somebody signed a decade ago rather than anything either side says in the room.

Did you already assign your goodwill to the entity in an old employment agreement? Are you bound by a restrictive covenant with your own practice?

Do the transaction documents actually treat this as a separate sale by you?

None of that can be assembled retroactively in a data room. The evidence exists before the deal or it does not exist.

Raise it early, then, with a CPA and an attorney who have argued the point before. Do not build your after-tax expectations on it.

Be wary of anyone presenting it as routine housekeeping rather than a position needing support.

Second reminder, and this is the section where it matters most: general information, not tax or legal advice.

How is deferred consideration taxed?

Is an earnout taxed differently from cash at closing? Usually in timing rather than character. Where a sale involves at least one payment after the tax year of the sale, the installment method applies automatically unless you elect out, spreading gain across the payments.

Depreciation recapture is the exception, reported in full in the year of sale.

Cash at close is the easy part. Known amount, known year, straightforward to model.

Everything else is a promise carrying a tax consequence, and the consequence does not always wait politely for the money to show up.

The earnout. Part of the price paid later, only if the practice hits agreed targets after closing. Because the total selling price cannot be pinned down by year end, contingent payment rules apply and the mechanics turn fiddly.

Your practical question is narrower. Is the earnout additional purchase price, or pay for your post-closing labour?

Those two produce different characters, and the second hauls employment taxes along with it. That difference lives in the drafting rather than the economics, which keeps it negotiable while documents remain open.

The holdback. A slice of the price the buyer retains for a period to secure your representations is still price. Deferred, at risk, and it needs its own row in your model.

Rolled equity. Rollover equity means keeping a slice of ownership in the buyer’s company instead of taking all cash at close, and its treatment turns wholly on how the exchange is papered.

Some rollovers are built so the exchange itself triggers nothing. Broadly, neither a partner nor a partnership recognises gain or loss when property is contributed for a partnership interest, though genuine exceptions exist for disguised sales and for liabilities assumed.

I am hedging on purpose, because whether a particular rollover defers anything depends on facts invisible from here, and the failure mode is expensive: units vesting against your continued employment can be treated as property received for services rather than as sale proceeds.

Which converts a slice of assumed capital gain into ordinary income. That surfaces after closing about as often as it gets caught before.

What the paper is worth, separately from how it is taxed, is covered in our piece on rollover equity and earnouts.

One pattern underlies all three. Tax follows the documents, and the documents are drafted by the buyer’s counsel unless somebody on your side is reading them for tax as well as for law.

How much does my state change the answer?

Does state tax change what I keep when I sell my practice? Enormously, and it is often the biggest variable after the allocation itself. Eight states levy no individual income tax at all, while the steepest top marginal individual rate in the country reaches 13.3 percent.

Several states also treat capital gains differently from ordinary income.

I am not offering a national state figure, because no honest one exists. What I can offer is the right set of questions.

Where are you resident on the closing date? Not where you practise. Residency tests are specific, states audit them, and a move made in the same calendar year as a sale invites attention.

Where does the practice itself sit? A state can generally reach income sourced inside it even from a non-resident, so a seller who has already relocated may face two sets of rules on one transaction.

Does your state follow the federal split between capital and ordinary, or flatten everything to one rate? Some flatten it, quietly erasing the state-level benefit of a well-argued allocation.

Is there a separate excise, surtax or add-on that only bites at large gains? Several states have introduced or repealed one recently. This layer moves.

Two dentists. Matching practices, matching prices, neighbouring states.

The spread between what they eventually bank can reach six figures without either of them negotiating a single clause differently, and neither will ever meet the other to compare notes.

Does the 3.8 percent net investment income tax apply to me?

Who pays the 3.8 percent net investment income tax on a practice sale? It applies to net investment income above modified adjusted gross income thresholds the IRS sets at $200,000 for single or head-of-household filers, $250,000 for married filing jointly, and $125,000 for married filing separately. Those thresholds are not indexed for inflation.

Here is the part most owners have never been told, and it is good news for the dentist still working chairside.

Net investment income generally excludes operating income from a non-passive activity. Gains on interests in partnerships and S corporations get pulled in to the extent the owner was a passive owner.

Translated: a dentist who materially participates in her own practice stands somewhere quite different from a silent investor in a second location. Plenty of owners assume the 3.8 percent is automatic when it may well not be.

Hedging again, deliberately. The rules governing pass-through interests carry more layers than one sentence holds, and material participation is a factual test with records behind it.

Two neighbours belong in the same conversation. A 0.9 percent Additional Medicare Tax applies to wages and self-employment income above $250,000 for joint filers, $125,000 filing separately, and $200,000 for everyone else.

That one lands squarely on whichever slices of a deal get characterised as compensation, which is one more reason to care whether an earnout or a consulting arrangement has been priced as consideration or as pay.

And if you own your building and lease it to your own practice, the rent and any later sale of the property carry their own analysis entirely. Separate decision, separate profile, separate modelling.

What should I do, and when is it too late?

Sequence is the whole game, so here it is in the order the calendar imposes.

Three or more years out: the structural work. An entity review with a CPA who has done practice sales. A basis schedule pulled and reconciled now rather than reconstructed later from memory.

Equipment purchases weighed against a sale window instead of only against this year’s tax bill. Any personal goodwill documentation created while it is still contemporaneous rather than convenient.

There is more runway than owners believe. ADA Health Policy Institute data puts average dentist retirement at 68.7 in 2024, up from 64.7 in 2001.

Most owners hold years of planning window and spend them not planning.

Twelve months out: the modelling. Both structures run in dollars, on your own numbers. Adjusted EBITDA documented properly, which in dentistry means bridging from collections through genuine operating overhead and the market-rate associate compensation your own production would cost to replace.

If that bridge is unfamiliar, our guide to what your dental practice is worth walks it.

At the letter of intent: the negotiable items. The allocation approach, at minimum a stated split between goodwill and everything else. The size and character of any covenant payment.

Whether post-closing pay is consideration or compensation. The holdback.

Whether you intend to elect out of the installment method.

After the letter of intent: very little. Exclusivity ends leverage, and nearly every item above resolves toward whoever still holds alternatives.

That is the honest argument for competition, and it is not really a tax argument at all. It is a leverage argument that happens to surface in your tax bill.

The buyer pool is deep. The Association of Dental Support Organizations counts more than 80 member companies, and Becker’s reported that 69 percent of DSOs expected a moderate or high increase in acquisition activity in 2026.

A DSO is a dental support organization: the management company owning the non-clinical side of a practice and handling everything outside the operatory, while a licensed dentist retains the clinical entity.

Independent ownership keeps thinning on the other side of that ledger. ADA Health Policy Institute figures put practice ownership at 72.5 percent of US dentists in 2023, down from 84.7 percent in 2005, with DSO affiliation reaching 16.1 percent in 2024.

Well-capitalised buyers, fewer independent practices. Scarcity sits on your side of the table, and a single-bidder conversation gives it away for nothing.

Which is what the Elite Selling System exists to build. We vet and approve every buyer before any of them may bid, the way a rope across the door of a good room leaves the doorman deciding who comes through instead of the crowd.

Then we run a private competitive window inside that approved group. A buyer aware that four others are studying the same practice treats an allocation request very differently from one who knows he is your only call.

What to do next

If an offer is already sitting in front of you, the first move is not to argue the price.

It is to find out what the price becomes.

Get your entity confirmed, your basis pulled, both structures modelled by a CPA experienced in dental transactions. Then have a dental transactions attorney read the allocation and the post-closing pay language before you sign anything, the letter of intent very much included.

And find out what the practice would draw from more than one qualified buyer before agreeing to talk to only one. The wider process sits in our overview of selling a dental practice.

We will tell you where you stand, free and in confidence, including when the honest answer is to fix two things and wait a year. It starts with a free, confidential practice value estimate.

Our fee varies depending on the value of the practice and is entirely success-based. If we do not get you a result, we do not get paid.

One last time, and this is the sentence I would most like you to keep. Everything above is general information and none of it is tax advice.

Your entity, your basis, your residency and your filing status move every figure on this page. The only version that counts is the one your own CPA models and your own attorney reviews.

Frequently asked questions

Do I pay capital gains tax on the whole sale price of my dental practice?

No. The IRS treats it as a sale of individual assets with gain figured separately on each.

Goodwill is generally capital gain, while recapture on equipment and any covenant not to compete are generally ordinary. Entity and state rules then layer on top.

What tax rate will I pay when I sell my dental practice?

Nobody can tell you without seeing your return. Long-term capital gain runs on its own schedule with 0, 15 and 20 percent steps keyed to taxable income, while ordinary slices ride your marginal bracket.

Those thresholds move annually, so model the closing year specifically.

What is depreciation recapture and why does it catch dental sellers out?

Gain on depreciable property is ordinary income to the extent of depreciation allowed or allowable. Write-offs claimed on chairs, imaging and cabinetry come back as ordinary income at sale, which is why an equipment-heavy allocation quietly costs money the seller never budgeted for.

Does purchase price allocation really affect what I keep?

Materially. Allocation fixes the tax character of each slice, and buyer and seller both report it to the IRS on Form 8594.

On a $4.2 million price, shifting 15 percentage points between goodwill and other classes moves $630,000 of consideration from one treatment into another.

Is personal goodwill worth pursuing in a dental practice sale?

Sometimes, and it counts most inside a C corporation, but the question is fact-specific and frequently contested. Supporting evidence must already exist in your employment and shareholder paperwork.

Raise it early with advisers who have argued it, and never build expectations on it.

How is an earnout taxed compared with cash at closing?

The difference is usually timing rather than character. Where at least one payment falls after the tax year of sale, the installment method applies unless you elect out.

Recapture is still reported in full in the year of sale, so tax and cash can land in separate years.

Do I owe the 3.8 percent net investment income tax when I sell my practice?

Not necessarily. It applies above modified adjusted gross income thresholds of $200,000 single, $250,000 married filing jointly and $125,000 married filing separately, none indexed for inflation.

Operating income from a non-passive activity is generally excluded, so material participation matters a great deal.

When does it become too late to change my tax outcome?

Practically, at the letter of intent. Entity structure, basis records and documentation all need years of lead time.

Allocation, covenant sizing and the character of post-closing pay stay live until you sign. Once exclusivity begins, open items resolve toward whoever still holds alternatives.
