Veterinary Practice Buy-Sell Agreement: Financial Planning Guide for Multi-Doctor Practices

If you co-own a veterinary practice and don't have a buy-sell agreement, you have a partnership with no plan for what happens when one of you dies, becomes disabled, or wants out. That's not a legal problem — it's a financial planning problem, because the moment one of those events occurs, the financial outcome for everyone is driven by default state law, not by a negotiated agreement made when everyone was healthy and on good terms.

What a buy-sell agreement is (and what it's not)

A buy-sell agreement (also called a business continuation agreement) is a legally binding contract among practice owners that pre-establishes:

• What events trigger a buyout — typically death, disability, retirement, voluntary departure, or involuntary departure (termination for cause)
• Who has the right or obligation to buy the departing owner's interest — the practice entity, the remaining owners, or a combination
• The price or the formula for calculating the price
• How the purchase will be funded
• The payment timeline and terms

What it's not: a buy-sell agreement is not the same as an operating agreement or partnership agreement, though both may cover some of the same ground. Your operating agreement governs the day-to-day mechanics of ownership. The buy-sell agreement specifically governs the transfer of that ownership — it activates when an exit event occurs.

For a single-owner practice, there is no buy-sell need. For a two-or-more doctor practice, not having one is one of the most common and most expensive financial planning oversights we see in veterinary practice ownership.

The three triggering events that matter most

Death

When a co-owner dies, their practice interest passes to their estate and then, typically, to their heirs — a spouse or adult children who may have no veterinary background and no desire to run a veterinary practice. Without a buy-sell agreement, the surviving owner(s) suddenly have a new co-owner they didn't choose, with a potentially different agenda.

A death trigger in the buy-sell agreement requires (or gives an option to require) that the deceased owner's estate sell the interest back to the practice or to the surviving owners at a predetermined price. The surviving owners can continue running the practice without disruption. The estate receives cash.

Disability

Long-term disability is the most likely severe-loss event in a veterinarian's career. Physical injury, zoonotic disease, and progressive neurological conditions can all end or severely limit a DVM's practice capacity. A disability trigger — typically defined as inability to perform material duties of the practice for 12–18 consecutive months — allows the practice to buy out the disabled owner's interest over time rather than carrying a non-productive equity holder indefinitely.

This is separate from individual disability income insurance, which replaces the disabled DVM's income. The buy-sell disability component addresses the equity stake — what the practice is worth and how the departing owner gets paid for it.

Departure: voluntary and involuntary

One owner wants to retire early. One owner wants to cash out to take a corporate job. One owner's clinical performance is declining, and the remaining partners want to force an exit. Each of these scenarios requires different pricing rules and timelines — and all should be defined in the agreement, not resolved in litigation.

Voluntary departure with notice typically gets market-rate pricing. Departure for cause (persistent non-performance, non-compete violation, embezzlement) can trigger a discount from formula value — the discount should be explicitly defined rather than implied.

Two ownership structures, two agreement types

How the buyout is structured financially depends on who buys the departing owner's interest: the remaining individuals or the practice entity. This choice has meaningful tax implications.

Cross-purchase agreement

In a cross-purchase structure, the surviving/remaining owners buy the departing owner's interest directly. Owner A buys out Owner B's shares; Owner C buys out Owner B's shares.

Tax advantage for the buyers: Each surviving owner gets a stepped-up cost basis equal to what they paid. When they eventually sell their own interests, their taxable gain is calculated from this higher basis — which can significantly reduce capital gains taxes at exit.

Complexity with multiple owners: In a three-owner practice, each owner must potentially hold life insurance on both others — that's six separate policies to fund death-trigger buyouts. Administration cost and complexity rise steeply beyond three owners.

Entity redemption agreement (stock redemption)

In a redemption structure, the practice entity buys back the departing owner's interest. The practice pays the buyout; the remaining owners' percentage interests increase proportionally without any transfer of funds between individual owners.

Simpler administration: The entity holds one life insurance policy per owner, not multiple policies between all owner pairs. This is manageable at any partnership size.

Tax disadvantage for surviving owners: Surviving owners don't get a stepped-up basis in a redemption. When they eventually sell, their taxable gain is calculated from their original purchase price — potentially creating a larger taxable event.

For S-corps specifically, entity-level life insurance death benefits can also affect the practice's accumulated adjustments account (AAA) in ways that require accounting attention.

Wait-and-see (hybrid) agreement

A hybrid structure gives the entity the first right of refusal to redeem, with the option for the remaining owners to step in and complete any portion the entity doesn't purchase. This is common in vet practices because it preserves flexibility on the tax-strategy side — the advisor can evaluate at the time of the triggering event which approach is more tax-efficient given then-current rates, the practice's financial position, and the specific circumstances.

Funding the buyout: the financial planning piece

Having a great buy-sell agreement on paper doesn't matter if the money isn't there to execute the buyout when a trigger event occurs. Four funding mechanisms are commonly used, often in combination:

Life insurance funding (death trigger)

For death-trigger buyouts, term or permanent life insurance is the standard funding mechanism. Each owner is insured for an amount approximately equal to the buyout value of their interest. In a cross-purchase structure, each owner holds policies on the others; in a redemption structure, the entity holds policies on each owner.

Critical for entity-owned policies: if the practice entity owns the policy and is the beneficiary, the insured employee (the DVM) must receive written notice and provide written consent before the policy is issued, per IRC §101(j).¹ Failure to comply means the death benefit is taxable income to the entity — eliminating much of the planning benefit. This requirement is routinely missed when a practice sets up entity-owned policies without coordination between their attorney, insurance advisor, and CPA.

Disability buyout insurance (disability trigger)

Separate from individual disability income insurance, disability buyout (DBO) policies pay the practice entity (or the purchasing owners) a lump sum or installment payments to fund the buyout of a disabled owner's equity. DBO policies typically have an elimination period of 12–24 months, matching the disability definition in the buy-sell agreement.

Not all insurers that write DVM individual disability policies also write DBO policies for vet practices — this is a specialized product. Your insurance advisor should be familiar with carriers that have experience with professional practice DBO, not just general commercial disability.

Installment payments (departure and planned exit triggers)

For retirement or voluntary departure — where there's typically no insurance funding — the buyout is usually structured as an installment note: the departing owner receives a down payment (10–30% of value) and then monthly or quarterly payments over a defined term (3–7 years is common in vet practice buyouts).

The interest rate on the note must meet IRS Applicable Federal Rate (AFR) minimums to avoid imputed interest treatment.² AFR rates are published monthly by the IRS; for multi-year installment notes, the mid-term AFR (3–9 year term) typically applies. As of mid-2026, mid-term AFR is in the 4.5–5.5% range depending on compounding interval — confirm the current month's rate at the time you execute the agreement.

Installment buyouts can create significant financial pressure on the practice. Before agreeing to a buyout timeline, model the cash flow impact: a $1.5M buyout paid over 5 years at 5% interest equals roughly $28,000/month in debt service. That's real working capital leaving the practice every month.

Sinking fund / reserve account

Some practices set aside a dedicated reserve account specifically to fund future buyouts. This doesn't help with sudden death events but provides liquidity for planned retirements. The downside: practice cash that could have been distributed to owners is instead sitting in a reserve account earning low returns, and the tax treatment depends on the entity structure.

The corporate sale clause: a provision unique to vet practices

This is the provision that most general-practice attorneys miss and that is uniquely critical for veterinary practices given active consolidation by Mars Petcare, NVA, MVP Veterinary Alliance, VCA, and regional groups.

When a corporate buyer approaches a multi-doctor vet practice, the deal is typically structured as a single transaction covering the entire practice — not individual owner interests. This means:

• All owners must agree to sell, or no deal gets done.
• The equity rollover offer from the corporate buyer (typically 10–30% of sale proceeds rolled into the acquirer's private equity) may be structured differently for each owner.
• One dissenting owner can block a sale that the majority wants to execute.

A corporate sale clause (also called a drag-along or tag-along right) addresses this directly:

• Drag-along right: If a supermajority of owners (e.g., 70% of equity) approves a sale to a corporate buyer, the remaining owners are obligated to sell their interests on the same per-share terms. Protects the majority from a minority holdout blocking a high-value corporate exit.
• Tag-along right: If the majority sells their interests to a corporate buyer, the minority owners have the right to sell on the same terms — rather than being left as a small-equity partner in a corporate-owned practice they didn't choose.

Equity rollover provisions should also be addressed: if Dr. Kim is 60 and wants all cash at close, but Dr. Reyes is 42 and willing to roll equity, the agreement should clarify whether each owner can independently decide their rollover percentage or whether the corporate deal requires a uniform rollover structure across all owners.

Valuation: locking in the price formula

One of the hardest parts of a buy-sell agreement is agreeing on how the practice will be valued at a future, unknown trigger date. Three approaches are common:

Fixed-price agreement

The owners agree on a specific dollar value for the whole practice, updated annually. Simple, but requires discipline — practices that skip the annual update end up with a stale price that benefits one party at the other's expense.

Formula-based valuation

The agreement specifies a formula: typically a multiple of EBITDA (average trailing 3-year EBITDA, multiplied by a fixed number) or a percentage of trailing-12-month collections. This automatically adjusts to the practice's actual performance.

For vet practices, the formula multiple should distinguish between a private-buyer exit and a corporate-buyer exit — the latter can be 2–3× higher. A formula pegged at 4× EBITDA will significantly undervalue an owner's interest if the trigger is death and the surviving owners then sell the practice to a corporate buyer at 10× EBITDA the following year. A well-drafted agreement specifies that if a corporate sale occurs within 24–36 months of a trigger buyout, the departed owner's estate participates in the upside above the formula price.

Appraisal-triggered valuation

The agreement requires an independent appraisal by a qualified business valuator (ideally one with veterinary practice experience — firms like Simmons or similar vet-specific valuation specialists) at the time of the trigger event. More accurate than a formula, but more expensive and slower.

Many agreements use a hybrid: a formula value as a baseline with an appraisal trigger if either party disputes the formula result beyond a defined threshold (e.g., more than 15% variation).

Tax implications for buyer and seller

The tax treatment of a practice buyout depends on the entity structure and the nature of the assets being transferred.

For the departing owner (seller)

In an asset sale or for LLC/partnership interests, the IRS generally treats goodwill as a capital gain, while non-compete payments and covenant-not-to-compete agreements are ordinary income. Personal goodwill doctrine (recognized in most states) can allow the DVM to allocate a portion of the goodwill to themselves personally — keeping that amount at capital gains rates rather than at the entity level.

For S-corp stock sales, the entire amount is typically capital gain (though the buyer will often push for an asset election under IRC §338(h)(10) to get stepped-up depreciation).³ Long-term capital gains rates in 2026: 0% (income below $48,350 single / $96,700 MFJ), 15% (up to $533,400 single / $600,050 MFJ), 20% above those thresholds. Net Investment Income Tax (NIIT) of 3.8% applies at $200,000 single / $250,000 MFJ MAGI.⁴

Section 1245 recapture on depreciated equipment is always ordinary income regardless of entity structure.

For the buying owner(s)

In a cross-purchase, the buying owner's new cost basis equals what they paid — which is useful when they eventually sell their own interest. In a redemption, the entity's basis in its own assets isn't directly affected by the buyout payment; remaining owners don't get a stepped-up basis in their interests.

Life insurance and income tax

Death benefit proceeds from a properly structured policy (individual ownership in cross-purchase, or entity ownership with IRC §101(j) compliance in redemption) are generally income-tax-free to the recipient. This is one of the primary reasons life insurance is the standard funding mechanism for death-trigger buyouts — the full face amount arrives tax-free at the moment it's needed.

Provisions to include for vet-specific situations

Beyond the standard buy-sell boilerplate, vet practice agreements benefit from these DVM-specific provisions:

• License suspension clause: What happens if an owner's veterinary license is suspended or revoked? This is an involuntary departure that the standard departure provisions may not cleanly handle. The agreement should specify whether license suspension triggers a forced buyout and at what valuation (typically discounted from normal formula value).
• Maternity/paternity/medical leave carve-out: An owner on parental leave for 3 months should not trigger the disability buyout clause. Define minimum duration thresholds clearly.
• Practice building ownership: If one owner also owns the real estate that the practice leases, the buy-sell agreement should clarify whether the building is part of the practice buyout or handled separately — and what happens to the lease if the building owner departs.
• Non-compete enforcement and radius: Post-buyout non-competes for departing owners should be calibrated to the actual trade area of the practice, not a generic radius. State law limits vary significantly (California and a few others ban most non-competes for employees; enforceability for practice owners who voluntarily sell their interest is more broadly recognized).
• Equity rollover vesting schedule: If any owner rolled equity into a corporate buyer, the vesting schedule for that rollover equity should be addressed if a subsequent departure occurs.

The financial planner's role in your buy-sell agreement

The buy-sell agreement is a legal document — an attorney drafts and executes it. But the financial planning content driving it requires a separate set of expertise:

• Sizing the life insurance policies: Coverage amounts should match current practice value, not the value at the time the agreement was signed three years ago. Annual review of policy face amounts is part of good practice financial hygiene.
• Selecting the right policy type: Term life is cheapest for death-trigger funding, but if an owner is older (60+) and term insurance is becoming expensive or unavailable, permanent insurance or a sinking fund may be more appropriate.
• Funding the disability buyout: DBO policy underwriting varies significantly. A financial advisor familiar with the veterinary practice market can source coverage from carriers with relevant experience.
• Modeling the installment buyout cash flow impact: Before agreeing to the payment terms of a voluntary departure provision, run the financial model: can the practice service the debt while still operating and investing normally? This is especially important when the departing owner is also the highest producer.
• Coordinating with estate planning: The buy-sell agreement creates specific rights and obligations for the owner's estate. This must be consistent with the owner's personal estate plan (trusts, beneficiary designations, etc.).

The worst time to figure this out is when the trigger event actually happens — when one owner has died and the surviving owner is simultaneously grieving and trying to keep the clinic running while the estate demands payment. A properly funded, well-drafted buy-sell agreement means that business continuation is mechanical and financially pre-arranged, not a crisis.
