Selling Your Practice: The Tax Bill Is Written Before the Closing
A $350K surprise tax bill after a practice sale is almost never bad luck. It is an allocation schedule nobody modeled and a timing decision nobody made.

The short answer
The tax outcome of a practice sale is decided by three choices made before closing: the form (equity sale, mostly capital gain, versus asset sale, taxed category by category), the allocation (goodwill versus equipment versus covenants, negotiated line by line and binding on both sides), and the timing (lump sum versus installment payments, with recapture due up front either way). Deferral levers exist, installment treatment, Opportunity Zone reinvestment for eligible gain, PE rollover equity, but every one must be arranged in the deal documents. After closing, the only planning left is arithmetic.
The allocation table: where the negotiation actually is
| Deal component | Seller's tax treatment | Buyer's incentive |
|---|---|---|
| Goodwill / going concern | Long-term capital gain | Slow 15-year amortization; buyers push dollars away from it |
| Equipment and furnishings | Ordinary recapture up to prior depreciation | Fast deductions; buyers push dollars toward it |
| Accounts receivable | Ordinary income | Neutral-ish; timing games only |
| Covenant not to compete | Ordinary income over the covenant term | Amortizable; buyers like it, sellers should resist overloading it |
| Consulting/employment agreements post-sale | Ordinary compensation (plus payroll tax) | Deductible immediately; a classic price-shifting pocket |
| Real estate (if included) | Its own gain + unrecaptured 1250 layer | Often better sold or leased separately |
Read the two incentive columns and the lesson writes itself: an unmodeled allocation drifts toward the buyer's preferences, converting your capital gain into ordinary income one line at a time. Sellers who arrive at the LOI with their own allocation model routinely keep several points of the purchase price that inattentive sellers donate. The same discipline applies in reverse on the way in, which is why this page and the buy-in guide are mirror images.
Timing levers: spreading, deferring, and the one that cannot move
Selling associate shares for $1.1M, basis $150K (illustrative)
- Lump sum: ~$950K gain in one year
- top capital gains bracket + NIIT; state tax on top
- Installment over 5 years (~$190K gain/yr)
- keeps most gain in lower LTCG brackets; NIIT exposure shrinks
- Tax difference across the two paths
- commonly mid five figures on these numbers
- Counterweights
- buyer default risk, interest-rate terms, and your reinvestment plans
- OZ alternative for part of the gain
- defers eligible gain if invested within 180 days; illiquid, quality-dependent
Installment treatment is bracket management, not magic: recapture-type income is recognized up front regardless of payment schedule, and a defaulting buyer converts a tax strategy into a collections problem. Model the paths side by side with your actual bracket picture. Illustrative numbers.
The PE letter of intent is a tax document wearing a business suit
If the sale is even two years out, the runway work is where most of the controllable tax value lives. Clean up the entity question first, discovering a C-corp wrapper eighteen months before closing leaves time for the S-election clock or a structure that supports personal-goodwill treatment; discovering it in diligence leaves time for nothing. Normalize the books next: buyers price and allocate off financials, and a practice whose owner expenses run through the P&L presents worse and allocates worse. Then position the assets: equipment nearing full depreciation argues for timing (new equipment bought just before a sale creates recapture with no offsetting use), the building decides whether it sells with the practice or becomes your lease income for a decade, and any cost segregation history feeds directly into the recapture math the allocation fight will be about. Finally, rehearse the allocation: build your own Form 8594 draft with your advisor before any buyer produces theirs, so the negotiation starts from your schedule. Sellers who do the two-year runway routinely keep several points of the price that unprepared sellers surrender in diligence, and none of it requires knowing who the buyer will be.

Frequently Asked Questions
How is the sale of a medical practice taxed?
It depends on what is sold. Selling your partnership interest or stock is mostly capital gain over your basis (with ordinary-income carve-outs for things like receivables and depreciated equipment in a partnership sale). An asset sale is taxed piece by piece: goodwill at capital gain rates, equipment as ordinary recapture, receivables as ordinary income, and a covenant not to compete as ordinary income over its term. The allocation schedule in the purchase agreement IS the tax outcome.
Why does the purchase price allocation matter so much?
Because every dollar shifted between categories changes rates for both sides. Sellers want dollars in goodwill and equity (capital gain); buyers want dollars in equipment and consulting agreements (fast deductions). The allocation is negotiated, binding on both parties via Form 8594 in asset deals, and worth real percentage points of the price. Never sign a letter of intent that fixes the price before anyone has modeled the allocation.
Can I spread the tax over time with an installment sale?
Partly. Seller financing lets capital gain be recognized as payments arrive under the installment rules, which can keep you out of top brackets and NIIT territory in any single year. But recapture on depreciated assets is recognized up front regardless of when you get paid, and buyer default risk is real. Installment treatment is a bracket-management tool, not a deferral of everything.
Can an Opportunity Zone investment defer my practice-sale gain?
Eligible capital gain (not the ordinary-income pieces) invested in a qualified opportunity fund within 180 days can be deferred under the current OZ rules, with basis benefits for long holds under the rules in effect when you invest. It is one lever among several, illiquid, investment-quality-dependent, and it should compete on merit against simply paying the capital gains rate, not win by default because a promoter reached you first.
What about selling to private equity with rollover equity?
PE deals typically pay part cash (taxed now) and part rollover equity in the buyer’s platform (often structured to be tax-deferred at closing). The rollover piece carries its own future tax profile, plus employment agreements, earnouts taxed as received, and sometimes ordinary-income compensation elements disguised inside the deal. PE letters of intent deserve tax counsel and a CPA modeling before signature, full stop.
How does selling gradually to an associate compare with an outside sale?
An internal succession typically trades price for structure: associates rarely outbid PE on headline number, but internal deals can be sequenced across years (spreading brackets), often keep goodwill treatment clean, and let you keep earning through the transition. The classic structure is a staged interest sale with seller financing, which is installment treatment doing bracket management by design.
Does it matter whether my practice is an S-corp, C-corp, or partnership when I sell?
Enormously. Partnership and S-corp sellers generally face one layer of tax; a C-corp asset sale faces corporate tax AND shareholder tax on the distribution, the double-tax trap that pushes C-corp sellers toward stock sales or personal-goodwill arguments. Old professional corporations hiding inside practices are a common late discovery. The wrapper should be reviewed years before a sale, when there is still time to restructure.
What happens to my retirement plans in the sale year?
The sale year is usually your last, best contribution year: full salary or self-employment income still exists, cash from the sale can fund the maximum employer contributions, and a practice with a cash balance plan may have a terminal funding opportunity worth six figures. Plans also need formal termination or successor handling in the deal documents, an item buyers’ counsel will raise if yours does not.
