Selling a Medical Practice: Goodwill, Non-Compete Agreements, and Capital Gains Tax Treatment

The single biggest driver of how much of the sale price a selling physician actually keeps after tax isn’t the total purchase price, it’s how that price gets allocated across goodwill, a non-compete agreement, accounts receivable, and equipment. Goodwill allocated to the seller personally, as distinct from the practice entity, and taxed as a long-term capital gain, can face a combined federal and state rate well under 30%. The same dollar allocated to a non-compete agreement or collected accounts receivable is ordinary income, potentially taxed at close to double that rate. Sellers who let the buyer’s advisor drive the entire allocation without pushing back are routinely leaving real money on the table, and the difference isn’t a rounding error, it’s often a six-figure swing on a mid-size practice sale.

What is the difference between personal and entity goodwill?

This distinction is the single highest-leverage planning point in a physician practice sale, and it turns on a factual question: does the goodwill being sold belong to the practice entity, or does it belong to the individual physician personally?

• Entity or practice goodwill is built into the business itself in a way that would transfer to a new owner or a new physician working under the practice’s name: an established brand and reputation in the community, transferable systems, staff, payer contracts, and a patient base that would largely stay with the practice location and infrastructure even under different clinical leadership.
• Personal goodwill belongs to the individual physician: their specific reputation, their personal relationships with referring physicians, and patient loyalty tied to that specific doctor rather than to the practice as an institution. Personal goodwill is a real, recognized, and separately valuable asset, and critically, it’s an asset the physician owns individually, not an asset of the practice entity, which means it can sometimes be sold directly by the physician to the buyer, outside the entity-level transaction, and taxed as the individual’s own long-term capital gain rather than flowing through the entity sale.
• The seminal case most often cited for this distinction in a professional practice context is Norwalk v. Commissioner, T.C. Memo. 1998-279, where the Tax Court found that two accountants (not physicians, but the same professional-practice logic applies and courts and practitioners routinely extend this reasoning to medical practice sales) had personal goodwill separate from any goodwill belonging to their accounting corporation, largely because neither had signed a non-compete or employment agreement with the corporation itself, which meant the corporation had no way to prevent them from taking their personal client relationships and walking away. The absence of such an agreement was central to the court’s finding that the corporation didn’t itself own that goodwill.
• The practical lesson from Norwalk and the line of cases following it: whether a physician has personal goodwill separate from the practice’s own goodwill depends heavily on the physician’s existing contractual relationship with the practice entity, specifically whether the physician was already bound by a non-compete or an employment agreement assigning their personal goodwill to the entity before the sale. A solo practitioner selling their own single-owner practice, with no prior non-compete running in favor of the entity, has the strongest facts for a personal goodwill argument. A physician who’s long operated under an employment agreement with an existing non-compete and an assignment-of-goodwill clause has a much weaker case, since that agreement likely already transferred the personal goodwill to the entity years before the sale.
• Because this is such a fact-intensive determination, and because the IRS scrutinizes personal goodwill allocations closely (it’s an area with real audit exposure if the facts don’t support the claimed split), the allocation needs contemporaneous support: an appraisal or valuation analysis distinguishing personal from entity goodwill, and documentation of the physician’s actual role in generating referrals and patient loyalty independent of the practice’s own systems and brand.

Why does the goodwill/non-compete allocation matter for tax?

Every dollar of the purchase price lands in one of several buckets, discussed in more detail in our practice acquisition guide from the buyer’s side, and each bucket carries a different tax character for the seller.

• Goodwill (entity-level or personal, per the discussion above) is a capital asset, and gain on its sale is generally taxed as long-term capital gain if held more than a year, at federal rates up to 20% plus the 3.8% net investment income tax under IRC 1411 for higher-income sellers, well below ordinary income rates that can reach 37% federally.
• A covenant not to compete is different in kind, not just in valuation. Under the broader body of case law and IRS guidance treating covenant payments as compensation for the seller’s agreement not to compete (rather than for the sale of a capital asset), amounts allocated to a non-compete are ordinary income to the seller, taxed at the seller’s marginal rate, regardless of how the buyer amortizes the same payment over 15 years under IRC 197 on their own return. This asymmetry, ordinary income to the seller, 15-year capital amortization to the buyer, is exactly why sellers have a strong incentive to minimize the non-compete allocation and maximize the goodwill allocation, while buyers are often more indifferent between the two since both amortize over the same 15 years on their side regardless.
• Accounts receivable collected by the buyer after closing (if the buyer purchased the receivables as part of the deal) generates ordinary income to whichever party ultimately recognizes it; if the receivables were already earned and would have been ordinary income to the seller if collected directly, transferring them in the sale doesn’t convert that character to capital gain.
• Equipment sold above its depreciated tax basis triggers depreciation recapture under IRC 1245, taxed as ordinary income up to the amount of depreciation previously claimed, with only the gain above original cost (rare for most medical equipment, which typically depreciates in value) qualifying for capital gain treatment.
• Because the buyer and seller both file Form 8594 reporting the same allocation (the mechanism discussed in our acquisition guide), the seller doesn’t get to quietly claim a more favorable allocation on their own return than what the buyer reports; the allocation has to be negotiated and agreed upon as a term of the deal itself, ideally before the purchase agreement is signed, not decided independently afterward.

How does an installment sale change the tax timing?

Most practice sales aren’t paid entirely in cash at closing; a meaningful portion is often financed by the buyer over several years, structured as an installment sale.

• IRC 453 allows a seller receiving payments over more than one tax year to recognize the capital gain portion of the sale proportionally as payments are received, rather than all at once in the year of sale, which spreads the tax liability across the payment period and can keep the seller in a lower marginal bracket in any given year than a single lump-sum recognition would.
• The installment method applies to the capital gain components (goodwill, the capital gain portion of any asset sold above basis) but does not defer ordinary income items the same way; depreciation recapture under IRC 1245 is generally required to be recognized in full in the year of sale regardless of the payment schedule, and non-compete payments are typically ordinary income as received under their own separate timing (often tied to when each annual non-compete payment is actually paid, if structured as a multi-year payment stream rather than a lump sum).
• A seller carrying a note from the buyer (seller financing) also takes on collection risk; if the buyer defaults partway through the installment period, the tax consequences of a repossession or a bad debt on the note are their own separate analysis, and a seller relying heavily on installment sale treatment should have the note properly secured and documented, not just handled as a handshake payment plan.
• Interest charged on any installment note is separately taxed as ordinary interest income to the seller, distinct from the gain recognition on the underlying sale price itself, and the IRS can impute a minimum interest rate under the below-market loan rules if the stated rate on a seller-financed note is too low relative to market rates at the time.

Do states restrict the sale of a practice or its goodwill?

Yes, in ways that vary significantly and interact with the corporate-practice-of-medicine doctrine discussed in our entity structure guide.

• Several states restrict who can own the equity in a medical practice entity, which constrains who can be the buyer in the first place; a practice can’t simply be sold to any purchaser with cash in a strict corporate-practice-of-medicine state, the buyer (or the buyer’s “friendly PC” structure, if it’s a private-equity-backed deal) has to satisfy the same physician-ownership requirements the seller originally operated under.
• Some states specifically regulate the transfer or sale of patient records and medical charts as part of a practice sale, requiring patient notification, a specified retention period for the transferring records, or in some cases patient consent before records transfer to a new owner, rules that sit alongside and independent of HIPAA’s own requirements around the transfer of protected health information in a business transaction.
• State licensing boards in some states require notice or approval before a change in practice ownership takes effect, particularly where the practice holds facility-level licenses (an ambulatory surgery center, an in-office lab under CLIA certification) that don’t automatically transfer to a new owner without a separate application or approval process.
• None of these state-level restrictions change the federal income tax analysis directly, but they affect the deal timeline and structure (a sale that can’t legally close until a licensing transfer is approved, for instance), which in turn affects when installment payments actually begin and when income is recognized, so they need to be mapped out early in the transaction, not discovered midway through due diligence.

What to do before signing a letter of intent to sell?

Get a valuation that explicitly separates personal goodwill from entity goodwill before the purchase agreement is drafted, not after, since the Norwalk analysis depends on facts (the physician’s existing non-compete and assignment history with the practice) that need to be documented, not asserted after the fact. Negotiate the purchase price allocation as an explicit, contested term of the deal, pushing to maximize goodwill and minimize the non-compete and receivables allocation where the facts support it, since the seller and buyer’s interests genuinely diverge here even though both sides amortize goodwill and the non-compete over the same 15 years on the buyer’s side. And confirm the state-level ownership, records-transfer, and licensing rules early, since they can dictate the deal’s actual closing timeline independent of anything in the purchase agreement itself.
