Selling a Veterinary Practice: The Tax Guide DVMs Don't Read Until It's Too Late

You've spent years building your practice. A $3M offer feels like a windfall. Then your CPA runs the numbers and you realize you might net $2M — or $1.7M — depending on how the deal is structured. The gap is taxes. This guide explains where every dollar goes and what you can do before signing to keep more of your proceeds.

Why the Tax Structure of a Practice Sale Matters More Than the Headline Number

Two DVMs each sell their practice for $2M. One nets $1.55M after federal taxes. The other nets $1.35M. Same sale price — $200,000 difference — because they structured the asset allocation differently at the time of sale.

The tax on a vet practice sale has three drivers:

1. Asset sale vs. stock sale: How the transaction is structured legally
2. Asset allocation: How the purchase price is divided across asset classes inside an asset sale
3. Pre-sale entity structure: Whether your practice is an S-corp, LLC, or C-corp changes the tax math significantly

None of these factors changes the buyer's total check. All of them change what you keep. And nearly all of them are negotiated before you sign — not after.

Step One: Asset Sale vs. Stock Sale

In a stock sale, the buyer acquires the practice's corporate stock (or LLC membership interest). The entire gain is treated as capital gain for the seller — taxed at 15–20% plus NIIT (3.8%), not at ordinary income rates. Good for the seller.

In an asset sale, the buyer acquires the practice's assets — equipment, patient records, goodwill, non-compete rights — one by one. The buyer gets a "stepped-up" basis on every asset, making future depreciation deductions available. Great for the buyer. Not uniformly great for the seller, because different assets are taxed at different rates.

The reality in veterinary practice transactions: nearly all are asset sales. Individual DVM buyers financed by SBA loans require asset sales to satisfy their lenders. Corporate buyers (Mars, NVA, MVP) also strongly prefer asset sales because the step-up provides significant deferred tax value. As a seller, you're usually negotiating the allocation within an asset sale, not choosing asset vs. stock.

The Asset Allocation Battle: Section 1060

In any asset sale, you and the buyer must agree on how to allocate the purchase price across asset classes. This allocation is reported to the IRS by both parties on Form 8594. The allocation must be consistent — you can't each report different numbers.

Under IRC Section 1060, assets are allocated in a specific order (Class I through Class VII). What matters to a DVM seller is the tax rate each class generates:

The core conflict is this: buyers want more allocation to equipment and non-compete (generates future deductions for them); sellers want more allocation to goodwill (generates capital gains rather than ordinary income). Both parties' CPAs negotiate this in parallel with the business negotiations.

Example: Same $1.5M deal, two allocations

The buyer isn't indifferent — a lower equipment allocation means less depreciation for them post-close. The final allocation usually reflects your relative negotiating leverage. On corporate deals where the buyer is using an 8–12× EBITDA multiple, there's often more room to negotiate allocation in the seller's favor because the overall economics already strongly favor the buyer.

Personal Goodwill: The Biggest Vet-Specific Tax Strategy

Here's where veterinary practices have a significant tax planning opportunity that many DVMs — and their CPAs — miss.

Personal goodwill is the portion of the practice's value that derives from you personally — your reputation in the community, your long-term client relationships, your clinical skills, your professional networks. This value belongs to you, not to the practice entity.

In a corporate practice sale where enterprise goodwill (the brand, location, established processes) is sold by the entity, personal goodwill can be sold separately — directly from you to the buyer — bypassing the practice entity entirely. For C-corps, this avoids the double-taxation problem (corporate tax on the gain, then dividend tax on the distribution). For S-corps and LLCs, it can clarify allocation and sometimes help with state tax treatment.

To support a personal goodwill claim:

• Document that clients return specifically because of you, not because of location or brand
• Show that the value would not transfer without you agreeing to the employment/non-compete terms
• Have a separate personal goodwill agreement as part of the deal documents
• Get independent valuation support for the personal vs. enterprise split if the amounts are material

The IRS has accepted personal goodwill arguments in veterinary and medical practice sales. The allocation must be reasonable and documented — a claim that 100% of goodwill is personal, when the practice has 3 associates and a strong brand, won't hold up. But 40–60% personal in a solo-DVM practice with strong referring-vet relationships? Plausible and defensible.

Capital Gains Rates in 2026

Goodwill and intangible assets get capital gains treatment. The 2026 federal rates:¹

Most DVMs selling a practice will have significant income in the year of sale and land in the 20% bracket for the capital gains portion. Add NIIT (below) and the effective federal rate on capital gain is often 23.8%.

The NIIT: The 3.8% Tax Most DVMs Forget

The Net Investment Income Tax (NIIT) adds 3.8% to certain types of investment income — including capital gains from the sale of a business — for higher-income taxpayers.²

NIIT thresholds (NOT adjusted for inflation — same every year):

• Single filers: 3.8% on net investment income above $200,000 MAGI
• Married filing jointly: 3.8% on net investment income above $250,000 MAGI

Nearly every DVM selling a practice will exceed these thresholds in the year of sale. That means the capital gains from goodwill and intangibles effectively face a 23.8% federal rate (20% + 3.8%), not just 20%. On $1M of goodwill proceeds, that's an additional $38,000 vs. ignoring NIIT.

There's one NIIT planning note for practice owners: if you materially participate in the practice and sell it, the gain may be characterized as active business income rather than passive investment income, which could exclude it from NIIT. This is a technical determination based on your participation level and entity structure — ask your CPA specifically about NIIT treatment on the sale before assuming it applies.

Section 1245 Recapture: The Equipment Problem

Any equipment you deducted through Section 179 or bonus depreciation — the $150K X-ray machine you wrote off in year one, the anesthesia monitors, the dental unit — is subject to Section 1245 depreciation recapture when you sell.³

The mechanic: if you bought equipment for $100K, deducted it all in year one, and it's now allocated $80K in the sale, the $80K is taxed as ordinary income (recapture), not capital gain. The IRS is recovering the tax benefit you received from accelerating depreciation.

For most vet practices, the recapture exposure is manageable — $50K–$200K total equipment value in a typical small-animal GP sale. But it adds up when you're already in the 32–37% bracket. On $150K of equipment recapture at 35%, that's $52,500 in federal tax at ordinary rates rather than the $35,700 you'd pay at 23.8% LTCG + NIIT.

Pre-sale planning note: if you're years away from selling and want to minimize recapture, consider slowing down Section 179 / bonus depreciation elections on new equipment purchases. Taking depreciation over the standard MACRS life instead of accelerating it results in less recapture on sale, though you lose the time-value benefit of earlier deductions. Whether that tradeoff makes sense depends on your expected sale timeline and rates — it's the kind of decision worth modeling with a CPA before you're in the year of sale.

State Taxes

Federal taxes are only part of the picture. Depending on your state, a practice sale can trigger 5–13% additional state income tax — in many states with no distinction between capital gains and ordinary income rates:

• California: No capital gains preference — all gains taxed at ordinary income rates up to 13.3%. A $1.5M gain in California could generate over $195K in state tax alone.
• New York: Capital gains taxed as ordinary income, up to 10.9% state + local (NYC adds another 3.876%). High-practice-value sales in NYC can result in 14%+ state/local marginal rates.
• Texas, Florida, Washington: No state income tax. A practice sale in Texas nets meaningfully more than an identical sale in California.
• Other states: Most have some form of capital gains tax at 4–9%. Check your specific state's treatment of business asset sales and goodwill.

If you're within 1–3 years of retirement and considering relocating, moving to a no-income-tax state before the sale is one of the highest-ROI financial moves available to you. The compliance rules require actually establishing domicile (not just spending 183 days somewhere) — get legal advice before assuming a move will work.

Installment Sale: Spreading the Tax Hit

Instead of receiving the full purchase price at close, you can elect an installment sale under IRC Section 453 — receiving payments over time and recognizing the gain as payments arrive. This can:

• Keep you in lower tax brackets in any single year by spreading income over multiple years
• Defer the tax liability, preserving cash for compound growth in the meantime
• Potentially avoid NIIT thresholds in lower-payment years (though unlikely if the payments are large)

The downside: you become an unsecured creditor of the buyer. If the practice fails under new ownership, you may not receive remaining payments. For private-buyer SBA deals where the practice generates the cash to pay you back, this risk is real — the buyer's SBA loan covers the down payment, but if the practice underperforms, earnouts and seller-note payments stop first. Installment sales work better when the buyer is well-capitalized or when a corporate group is the counterparty.

Equity Rollover in Corporate Deals

Corporate buyers (Mars, NVA, MVP, Southern Veterinary Partners) typically structure a portion of the deal as equity rollover — you receive equity in the corporate parent rather than cash for 10–30% of the purchase price.

The tax implication: rolled equity is generally not taxed at close. You receive corporate parent equity on a tax-deferred basis, recognizing gain only when you eventually sell those units. This creates a two-phase tax event:

1. At close: Tax on the cash portion only (allocated as above)
2. At equity liquidation (5–10 years later): Tax on the equity appreciation — typically capital gains if the units are long-term held

The rollover is not free money. You're accepting risk that the corporate parent will achieve an exit at a favorable multiple — which requires the PE sponsor behind the consolidator to execute a successful recapitalization or IPO. Some rollover equity has performed well; others have been written down significantly when PE-backed vet consolidators ran into financial trouble. Model it as "high-risk equity with uncertain timing" rather than guaranteed deferred compensation.

If you receive significant equity rollover, discuss with your CPA whether a 83(b) election applies, what the basis rules are in your state, and how to think about the deferred tax liability relative to the equity risk in the parent company.

Pre-Sale Planning: What to Do 2–5 Years Out

The most valuable tax planning happens before you're in a sale process. Once you're under LOI, most structural decisions are locked.

Entity structure cleanup

If you're operating as a C-corp, consider converting to an S-corp election 5+ years before the intended sale date. A C-corp asset sale generates double taxation: the corporate entity pays tax on the gain, and then you pay tax on the distribution. An S-corp passes the gain directly to you, eliminating the corporate layer. The 5-year waiting period matters because built-in gains (BIG) rules apply for the first 5 years after S-corp conversion — gains on assets that appreciated before the conversion still get taxed at the corporate level.

Document personal goodwill now

Establish your personal goodwill claim before you're in a sale. This means: document the personal referral relationships, the fact that clients follow you (not just the clinic), and the role your reputation plays in driving revenue. Having this documented before a buyer shows up makes the personal goodwill allocation argument significantly stronger.

Watch depreciation elections in the final 3 years

Every dollar of bonus depreciation or Section 179 you take now creates ordinary income recapture when you sell. In the 3 years before an anticipated sale, model whether slowing depreciation on major equipment purchases reduces your overall tax load at exit. The answer isn't always to slow down — if your marginal rate is higher in the year of sale than in the years before it, accelerating earlier still wins.

Plan the installment sale option in advance

If you're considering a private-buyer sale with an installment note, structure the note terms in advance. Decide how much seller financing you're willing to provide, at what rate, and with what security. Having a position before entering negotiations prevents you from accepting unfavorable note terms under time pressure at closing.
