Buy-Sell Agreements: Protecting Business Owners and Partners

A buy-sell agreement is a legally binding contract among the owners of a closely held business — whether a corporation, LLC, or partnership — that governs what happens to an owner's equity interest when certain triggering events occur (death, disability, retirement, divorce, bankruptcy, or voluntary departure). Often called a "business prenuptial agreement," it is one of the most important documents in any multi-owner business because it answers the question no owner wants to face without an answer: who can own the business, on what terms, and at what price?

Why Buy-Sell Agreements Are Essential. Without a buy-sell agreement, a triggering event can force co-owners into business with someone they never chose — a deceased owner's spouse, an estranged partner's creditors, or a former colleague who wants to cash out at the worst possible time. Courts apply default statutory rules that rarely match the owners' intent. A well-drafted buy-sell agreement replaces those defaults with a predictable, pre-negotiated framework that protects all owners.

Entity Purchase (Redemption) Structure. In an entity purchase (also called a "stock redemption" for corporations or "interest redemption" for LLCs and partnerships), the company itself buys back the departing owner's interest. Advantages: fewer insurance policies needed (the company holds one policy per owner), simpler administration with many owners, and the surviving owners' percentage interests automatically increase without them needing personal capital. Disadvantages: In a C corporation, a redemption may be treated as a dividend rather than a capital gain under IRC § 302 if the redemption is not "substantially disproportionate" — creating ordinary income tax treatment. The remaining owners also receive no step-up in the basis of their interests, while cross-purchase buyers do.

Cross-Purchase Structure. In a cross-purchase agreement, the surviving owners — not the company — buy the departing owner's interest directly. Each owner owns a life insurance policy on each other owner. Advantages: the purchasing owners receive a full stepped-up basis in the purchased interests, which matters when they ultimately sell. Disadvantages: the number of required insurance policies grows geometrically with the number of owners (N × (N − 1) policies for N owners); with five or more owners, the administrative complexity is substantial. Cross-purchase arrangements also require owners to have the personal capital or insurance proceeds to fund the purchase.

Hybrid / Wait-and-See Structure. The hybrid (or "wait-and-see") buy-sell agreement avoids committing to entity purchase or cross-purchase at execution. When a triggering event occurs, the agreement gives the company the first option to redeem, then gives the surviving owners the second option to purchase, and if neither exercises, the parties proceed to a mandatory redemption. This flexibility is valuable when future tax law, ownership structure, or business circumstances make it premature to lock in a structure. The trade-off is that the decision point during a triggering event — which may be emotionally charged — requires the parties to actively choose, potentially creating conflict.

Who Needs a Buy-Sell Agreement. Any business with two or more owners who want control over who can become a co-owner, who want a fair and predetermined mechanism for valuing interests, and who want to avoid the chaos of a forced sale or a court-supervised buyout should have a buy-sell agreement in place from Day One. It is far easier to negotiate terms when all owners are healthy, financially stable, and emotionally aligned than when a triggering event is already underway.

The definition of triggering events is the foundation of any buy-sell agreement. A triggering event is the circumstance that activates the buyout mechanism. The precision with which each trigger is defined — and the specific consequences attached to each — will determine whether the agreement functions as intended when it is needed most.

Death. Death is the most common trigger and is usually the easiest to define. The agreement should specify the timeline for initiating the buyout after death (typically 30–90 days from the appointment of a personal representative or the probate of the will), who bears the administrative costs of valuation and transfer, and how the purchase price is funded (usually life insurance proceeds). A gap between the date of death and the ownership transfer can create governance uncertainty if the deceased owner's estate becomes a de facto co-owner during the interim. Address this by specifying that the estate has no voting rights and only economic rights during the transition period.

Disability. Disability is the most difficult trigger to define cleanly. Owners often disagree about when a co-owner is truly "permanently disabled" in ways that eliminate their ability to contribute — rather than temporarily incapacitated. The agreement should specify a clinical definition of disability (typically tied to an inability to perform material duties for a defined period, such as 180 consecutive days, or consistent with the definition used in any disability insurance policy), who determines whether the standard is met (typically the company's physician or a mutually agreed specialist), and whether a disability buyout is mandatory, optional, or subject to a waiting period.

Retirement. Retirement triggers require clear definitions of what "retirement" means: Is it age-based? Is it a voluntary cessation of all active duties? What if an owner wants to reduce hours but remain involved? The agreement should address whether a partial reduction in duties triggers any buyout right, whether there is a minimum age or service threshold before retirement is recognized as a trigger, and whether an owner who "retires" can return to active participation — and if so, under what conditions.

Divorce. Divorce protection is one of the most overlooked triggers. In community property states, a spouse may have a legal ownership interest in the owner's business interest simply by virtue of the marriage. In all states, divorce proceedings can result in a court awarding a portion of the business interest to the non-owner spouse. A well-drafted buy-sell agreement addresses divorce by: (1) defining a divorce-related trigger broadly enough to cover any attempt by a spouse or domestic partner to claim an ownership interest; (2) establishing that the non-owner spouse can only receive the fair market value of the interest in cash — not the interest itself; and (3) requiring owners to have their spouses execute a spousal consent acknowledging the buy-sell agreement's terms.

Bankruptcy. Bankruptcy is a critical trigger because a bankrupt owner's interest becomes part of the bankruptcy estate, potentially transferring ownership to a trustee who represents creditors — not the business. Triggering a buyout upon the filing of any bankruptcy petition (voluntary or involuntary) ensures that the surviving owners can purchase the interest before the bankruptcy trustee can attempt to sell it to a third party. Note: bankruptcy buyouts may require approval from the bankruptcy court, and the purchase price must meet the court's "reasonably equivalent value" standard to avoid avoidance as a fraudulent transfer.

Voluntary Departure. Voluntary departure triggers — an owner who simply wants to leave the business — require the most careful drafting. Key questions: Is the buyout mandatory (the company or co-owners must buy) or optional (the departing owner can sell but no one must buy)? Is there a "good leaver / bad leaver" distinction, where owners who depart under different circumstances receive different valuations? Is there a lock-up period during which voluntary departure triggers are not available? These design choices significantly affect the economics of departure for all parties.

Valuation is the core economic mechanism of any buy-sell agreement. The method you choose determines how much money changes hands when a trigger event occurs — and whether that amount is fair to both the departing owner and the surviving owners. Choose the wrong method, and you may face a buyout that destroys the business, leads to protracted litigation, or produces a price that no one accepts.

Method 1: Fixed Price. The owners agree on a specific dollar value for the entire business (or for each owner's interest), which is stated in the agreement and updated periodically. Simple and certain — but stale within months unless the parties actually update it. Most fixed-price provisions fail because owners agree to annual valuation updates at signing but never actually conduct them. Within three to five years, the fixed price is almost always significantly disconnected from reality. A fixed price that is too low advantages the buyers; one that is too high makes the buyout unaffordable. Recommended only where the owners commit contractually to an annual update process with binding consequences for non-compliance.

Method 2: Formula. A formula-based valuation applies a mathematical calculation to financial data — for example, "five times the average EBITDA for the three most recent fiscal years" or "1.5 times trailing twelve-month gross revenue." Formulas have the advantage of predictability and automatic updating as financial results change. The risks: the formula may not be appropriate for all industry conditions or business life-cycle stages; the owners may disagree on the inputs (what is included in EBITDA, which adjustments are appropriate); and formulas rarely capture the full economic value of a business at any given moment. The formula also fixes the valuation methodology regardless of whether the business has changed character significantly since the agreement was signed.

Method 3: Independent Appraisal. Professional appraisal by a certified business valuator (CBV) or accredited senior appraiser (ASA) applying standard valuation methodologies is the most accurate but most expensive and time-consuming approach. The clause above illustrates a three-appraiser process that provides a check on outlier appraisals but can take six months or more and cost tens of thousands of dollars. A common compromise: a single appraiser agreed upon by all parties, with a disagreement fallback to the three-appraiser structure. Appraisal is most appropriate for larger businesses where the economic stakes justify the cost.

Method 4: Capitalization of Earnings. A specific formula approach that divides normalized earnings (typically an average of the last three to five years of net income or EBITDA) by a capitalization rate that reflects the risk and marketability of the business. The capitalization rate is typically derived from industry comparables and risk factors specific to the business. The challenge: "normalized earnings" requires adjustment for owner compensation, non-recurring items, and related-party transactions, all of which are subject to dispute. The capitalization rate is also an input that both parties will attempt to influence to their advantage.

Method 5: Book Value. Book value — the net asset value of the business as reflected on its balance sheet — is the simplest but usually least appropriate method for operating businesses. Book value ignores goodwill, customer relationships, brand value, intellectual property, and earnings power — all of which typically comprise the majority of a business's economic value. Book value is most appropriate for holding companies or asset-intensive businesses where balance sheet values closely approximate market values. For most service businesses, professional practices, or technology companies, book value significantly undervalues the business.

Knowing what triggers the buyout and how the purchase price is calculated only matters if someone can actually pay for it. Underfunded buy-sell agreements — where the obligation exists but the money does not — are among the most common causes of business failure and family financial tragedy following the death or disability of a business owner.

Life Insurance Funding. Life insurance is the preferred funding mechanism for death-triggered buyouts because it provides a large, predictable sum of money at exactly the moment it is needed — without straining the business's cash reserves. In an entity purchase structure, the company owns and is the beneficiary of a policy on each owner's life. In a cross-purchase structure, each owner owns and is the beneficiary of a policy on each other owner's life. Under IRC § 101(a), life insurance death benefit proceeds received by a corporate beneficiary are generally income-tax-free, though they may be subject to the corporate alternative minimum tax (AMT) for C corporations. Key issues: the insurance amount must be updated as the business grows in value; policies must remain in force; and the agreement should specify what happens if the policy lapses or the insurer becomes insolvent.

Disability Insurance Funding. Disability buyouts present a funding challenge because the owner is still alive, and life insurance proceeds are not available. Disability buyout insurance (a specialized product distinct from regular disability income insurance) pays a lump sum or installment benefit upon the permanent disability of a business owner, designed specifically to fund a disability-triggered buyout. The benefit must be sized to match the agreed purchase price. Without disability buyout insurance, a disability buyout typically falls back on installment payments funded from business cash flow — which can be burdensome for the remaining owners and the business.

Installment Note Payments. When insurance proceeds are unavailable or insufficient, the purchase price is often paid through an installment promissory note — a structured payment obligation with a fixed interest rate, payment schedule, and term. The agreement should specify: the interest rate (typically the Applicable Federal Rate (AFR) published monthly by the IRS, which is the minimum rate required to avoid imputed interest under IRC § 7872), the payment term (typically three to ten years), the security for the note (pledge of the purchased interests, guarantee, or other collateral), and what acceleration events trigger the full balance becoming due (for example, a sale of the company or a subsequent trigger event affecting the purchasing party). Installment notes create ongoing financial obligations for the company and surviving owners that can affect business operations and creditworthiness.

Sinking Fund. Some buy-sell agreements require the company or owners to build a dedicated reserve — a sinking fund — over time to be used for future buyout obligations. The sinking fund approach is most appropriate for anticipated buyouts (such as a planned retirement of a majority owner) where the timeline is known. The challenges: sinking fund balances earn a return but are not tax-advantaged, funds may be diverted to business needs, and the fund may be insufficient if the trigger event occurs earlier than anticipated or the business grows faster than expected.

Company Surplus and Retained Earnings. For many small businesses, the most realistic funding source for any non-death-triggered buyout is the company's available cash and retained earnings. The buy-sell agreement should address whether the company has authority to borrow to fund a buyout, whether existing lenders must consent to the buyout obligation (most commercial loan covenants restrict distributions and equity redemptions), and whether there is a minimum cash reserve the company must maintain before a buyout can be completed. Triggering a buyout when the business lacks the liquidity to fund it can force a premature sale of the business itself — the exact outcome the buy-sell agreement was designed to prevent.

Who must buy, and who has only the option to buy, fundamentally shapes the economic dynamics of a buy-sell agreement. A mandatory buyout means someone is obligated to buy the departing owner's interest — the departing owner cannot be "stranded" without an exit. An optional buyout means someone has the right to buy but is not required to — the departing owner may find that no one exercises the option, leaving the interest unmarketable.

Put Rights. A "put right" is the departing owner's right to force the company or the other owners to purchase the interest — regardless of whether they want to. Put rights provide the departing owner with an assured exit and a guaranteed liquidity event. The trade-off from the business's perspective: a mandatory buyout obligation can drain company liquidity or force a debt-financed purchase at an inconvenient time. Many buy-sell agreements grant put rights only after a waiting period, only above a certain ownership threshold, or only in connection with specific trigger events (death and disability) rather than voluntary departure.

Call Rights. A "call right" is the company's or surviving owners' right to compel the departing owner (or the departing owner's estate) to sell the interest — regardless of whether the departing owner wants to sell. Call rights protect the remaining owners from an unwanted co-owner (such as a deceased owner's heirs or a bankrupt owner's trustee) retaining an interest. Call rights are typically exercisable for a specified period following a trigger event, at the purchase price determined by the agreement's valuation method.

Right of First Refusal (ROFR). A ROFR requires an owner who has received a bona fide third-party offer to sell the interest to first offer the interest to the company and/or the other owners at the same price and on the same terms as the third-party offer. The remaining owners have a specified time to match the offer. If they match, the sale goes to them rather than to the third party. If they do not match, the owner can sell to the third party — but only on terms no more favorable than those offered to the existing owners. A ROFR is the most common transfer restriction in buy-sell agreements but has a key disadvantage: it can deter third-party buyers who are unwilling to invest time negotiating a deal only to be outbid by the existing owners on identical terms.

Right of First Offer (ROFO). A ROFO requires an owner who wants to sell to first offer the interest to the company and/or the other owners at a price the selling owner proposes, before marketing the interest to third parties. If the existing owners decline, the selling owner can then solicit third-party offers — but typically cannot sell to a third party at a price lower than the ROFO price without reoffering to the existing owners. A ROFO is friendlier to potential third-party buyers (no one negotiated a deal only to have it matched) but gives the selling owner more control over the initial pricing, which may be set opportunistically.

Good Leaver / Bad Leaver Distinctions. Many buy-sell agreements provide different treatment for departing owners depending on the circumstances of departure. A "good leaver" — one who departs voluntarily after a specified tenure, due to retirement, disability, or death — typically receives full fair market value for their interest. A "bad leaver" — one who departs in breach of a non-compete, is terminated for cause, or voluntarily departs within a lock-up period — may receive only book value, a discounted price, or a price capped at the original capital contribution. Good leaver/bad leaver provisions incentivize long-term commitment but require careful drafting to avoid unintended outcomes.

Transfer restrictions are the mechanism by which existing owners maintain control over who their co-owners are. Without effective transfer restrictions, any owner can sell, gift, pledge, or assign their interest to virtually anyone — including a competitor, a creditor, or a hostile party — without the consent of the remaining owners. In a closely held business where the co-owner relationship is essentially personal, unrestricted transfers can be devastating.

The Scope of "Transfer." The first drafting task is defining what constitutes a "Transfer." A comprehensive definition includes not only outright sales but also: gifts, pledges or assignments as collateral for a loan, transfers pursuant to divorce decree, transfers through probate or intestate succession, transfers by operation of law in a bankruptcy proceeding, and indirect transfers through a change in control of an entity that owns the business interest. Particularly important is coverage of indirect transfers — an owner who holds their interest through a personal holding company can effectively transfer the business interest by selling the holding company without triggering the buy-sell agreement's restrictions.

Consent Requirements. Most transfer restrictions require the consent of all other owners, or of owners holding a supermajority of the outstanding interests, before any voluntary transfer is effective. Consent provisions should specify: (1) who must consent (all owners, a majority, a supermajority); (2) the time period within which consent must be granted or denied; (3) whether consent can be withheld for any reason or only for specified reasons; and (4) what happens if consent is neither granted nor denied within the time period (typically treated as a denial). Open-ended consent requirements that allow any owner to withhold consent for any reason (or no reason) provide maximum control but create potential for abuse.

Permitted Transferees. Most buy-sell agreements carve out "permitted transfers" — transfers to specified related parties that do not require co-owner consent. Common permitted transferees include: revocable living trusts (for estate planning), family limited partnerships or LLCs wholly controlled by the owner, immediate family members (spouse, children, parents), and certain qualified plans. The key requirement for any permitted transfer: the transferee must execute a joinder agreement binding them to all the obligations of the buy-sell agreement. Without the joinder requirement, the permitted transfer exception can become a loophole — the owner has effectively transferred to a third party who is not bound by the transfer restrictions or buyout obligations.

Effect of Unauthorized Transfers. The clause above states that unauthorized transfers are "null and void ab initio" — legally never occurred. This is the standard remedy but requires the company to actually enforce it, typically through litigation. An alternative (or additional) remedy is redemption: the company has the right to redeem the transferred interest at the original cost basis if an unauthorized transfer occurs, effectively penalizing the transferring owner for the breach. Either approach requires active monitoring and prompt enforcement — delayed enforcement creates the risk of waiver or estoppel arguments from the transferee.

Pledges and Loans Secured by Interests. When an owner pledges their business interest as collateral for a personal or business loan, a default on the loan can result in the lender taking ownership of the interest — a transfer to an involuntary, unexpected co-owner. Buy-sell agreements should expressly address pledges: either prohibiting them entirely (common for small businesses where lenders may not accept such collateral anyway), or requiring lender acknowledgment of the transfer restrictions and agreement that any enforcement of the pledge is subject to the buy-sell agreement's ROFR or consent requirements.

Disability provisions are the most technically complex and emotionally sensitive provisions in a buy-sell agreement. The disability of a co-owner creates a unique challenge: unlike death, it involves an owner who is still alive, still has legal capacity to contest valuations and procedures, and whose condition may be uncertain, contested, or expected to improve — all while the business continues to operate and the remaining owners must make critical decisions.

Defining Disability — Why Precision Matters. The definition of "permanent disability" is the linchpin of the disability buyout mechanism. An overly broad definition (any inability to perform any duties for any period) can trigger a buyout for a temporary injury, imposing financial burden on the business and hardship on the disabled owner. An overly narrow definition (complete and total incapacity for two or more years) may never be met, leaving the remaining owners with an unproductive co-owner indefinitely. The clause above ties the definition to a 12-month period of incapacity — consistent with the Social Security Administration's definition of disability — and requires the owner to be unable to engage in "substantial gainful activity" in the specific role they perform for the business.

Coordination with Disability Insurance. The practical solution to definition disputes is to tie the buy-sell agreement's disability definition to the definition used in an existing disability insurance policy — and to designate the insurance company's determination of disability as conclusive or at least persuasive evidence for buy-sell purposes. This approach aligns the definition with the funding source and leverages the insurer's expertise in making disability determinations. The limitation: if no disability buyout insurance is in place, or if the insurance policy lapses, the definition is unmoored from any external standard.

Temporary vs. Permanent Disability. The agreement must clearly distinguish between temporary incapacity (which should not trigger a buyout) and permanent disability (which should). During a period of temporary disability, the affected owner typically remains an owner but may have their compensation reduced to reflect their reduced contribution to the business. A stated waiting period — 90 days, 180 days, or 12 months — before the buyout right is triggered helps prevent buyout proceedings from beginning while an owner is recovering from a temporary condition.

Disputed Disability Determinations. An owner who is told their co-owners want to buy them out as "permanently disabled" is likely to dispute that determination — especially if they believe they will recover or if the buyout price is unfavorable. The agreement must specify a neutral, binding dispute resolution mechanism for disability determinations. The physician selection process in the clause above — with AAA appointment as a fallback — is a standard approach. Some agreements add a requirement for two concurring independent physician opinions. Litigation over disability determinations is expensive and destructive to the business; a clear, neutral process mitigates this risk significantly.

Management Rights During Disability. The agreement should address whether and to what extent a temporarily or permanently disabled owner retains voting rights, management rights, and economic rights during the transition period. Allowing a functionally incapacitated owner to retain full voting rights while a buyout proceeds can paralyze the business. Most well-drafted agreements provide that during any disability waiting period or pending disability determination, the disabled owner's voting rights are suspended and exercised by a designated proxy or by the company's other managers.

Divorce is one of the most disruptive events that can affect a closely held business. Without robust divorce protections in the buy-sell agreement, a co-owner's divorce can result in a court awarding a business interest — or the economic equivalent — to a non-owner spouse who becomes an unexpected and potentially hostile co-owner or economic participant in the business.

Community Property States. Nine states have community property regimes: Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin (and Alaska by opt-in election). In community property states, all property acquired during the marriage (with exceptions for gifts and inheritances) is presumptively owned equally by both spouses, regardless of whose name is on the title. This means that in a community property state, a spouse may have a legal ownership claim to half the business interest acquired during the marriage — even if the business interest is titled solely in the owner's name. Without a prenuptial agreement or the terms of the buy-sell agreement expressly addressing community property, a divorce proceeding can result in the non-owner spouse having an ownership interest in the business.

Common Law Property States. In the remaining 41 states and D.C., property acquired during marriage is titled to the spouse who earned or purchased it. However, courts in common law states apply "equitable distribution" principles in divorce proceedings — dividing marital assets (including business interests) in a manner the court deems fair, which is not necessarily equal. Business interests acquired or appreciated during the marriage are typically treated as marital assets subject to equitable distribution. Even in common law states, a buy-sell agreement without divorce protections can result in a court awarding a significant economic interest to the non-owner spouse.

The Spousal Consent Solution. The most effective divorce protection is a spousal consent — a document signed by the non-owner spouse that acknowledges the buy-sell agreement's terms and agrees that the non-owner spouse's entitlement in any divorce proceeding is limited to the monetary value of the business interest (as determined by the buy-sell agreement's valuation method) rather than the interest itself. This prevents the non-owner spouse from demanding to become a co-owner as a result of a divorce. The spousal consent should be obtained at signing (for currently married owners) and as a condition of any future marriage (for currently unmarried owners), and upon any material amendment to the buy-sell agreement.

Enforceability of Spousal Consents. Spousal consents are generally enforceable but face scrutiny in some jurisdictions when they operate as a waiver of marital property rights. For maximum enforceability: (1) the non-owner spouse should be advised by independent counsel before signing; (2) the consent should be specific about what is being waived; (3) consideration should be adequate (the mutual agreement among all owners to be bound by the same terms is typically sufficient); and (4) the consent should be updated whenever the buy-sell agreement is materially amended. Courts in community property states are particularly rigorous in scrutinizing spousal waivers of community property rights.

Divorce-Triggered Buyout Mechanics. Beyond preventing the non-owner spouse from becoming a co-owner, the buy-sell agreement should specify what happens when a divorce proceeding is initiated: (1) Does the filing of divorce proceedings itself trigger the buyout right? (2) If so, is the buyout mandatory or optional? (3) What is the timing — can the buyout occur before the divorce is finalized? (4) Does the owner whose spouse has filed receive any special treatment (for example, does the owner's voting rights remain intact during the divorce proceedings)? These mechanics must be addressed in the agreement to prevent ambiguity during what is already a difficult personal and legal situation.

Buy-sell agreements intersect with federal tax law in several critical ways. Getting the structure right can produce significant tax savings; getting it wrong can result in unexpected taxable income, estate tax inclusion of business interests at values far higher than the purchase price, and basis step-up strategies that fail. These are not hypothetical concerns — each of the issues below has resulted in substantial, documented taxpayer losses that proper planning could have avoided.

IRC § 2703 — Estate Tax Valuation. Section 2703 of the Internal Revenue Code provides that for estate tax purposes, the value of property is determined without regard to any option, agreement, or other right to acquire or use the property at a price less than fair market value. In other words, a buy-sell agreement that fixes the purchase price below actual fair market value cannot be used to "lock in" a low estate tax value for the business interest — unless the agreement meets the § 2703(b) safe harbor. The safe harbor requires: (1) the agreement is a bona fide business arrangement, (2) it is not a device to transfer property to members of the decedent's family for less than full and adequate consideration, and (3) its terms are comparable to similar arrangements entered into by persons in arm's-length transactions. A below-market fixed price in a buy-sell agreement will be ignored for estate tax purposes unless all three § 2703(b) requirements are met.

IRC § 101(a) — Life Insurance Proceeds. Under IRC § 101(a), death benefits paid under a life insurance contract are generally excluded from the beneficiary's gross income. This exclusion applies whether the beneficiary is the business (in an entity purchase structure) or the other owners personally (in a cross-purchase structure). However, there is an important exception: the "transfer for value" rule. Under IRC § 101(a)(2), if a life insurance policy is transferred for valuable consideration (i.e., sold), the death benefit is taxable to the extent it exceeds the buyer's basis (what they paid for the policy plus any subsequent premiums paid). This is particularly relevant when a cross-purchase agreement is converted to an entity purchase structure and policies are transferred from one owner to another — or when a policy is sold incident to a business ownership change.

§ 302 Redemption — Corporate Settings. When a C corporation redeems a shareholder's stock under a buy-sell agreement, the tax treatment of the redemption payment to the departing shareholder depends on whether the redemption qualifies as a "sale or exchange" under IRC § 302 or is treated as a taxable dividend distribution under IRC § 301. A distribution qualifies as a § 302 sale or exchange (producing capital gain treatment) only if it is: (a) not essentially equivalent to a dividend; (b) substantially disproportionate (the shareholder's interest drops below 80% of the pre-redemption percentage and below 50% of total voting power); (c) a complete termination of the shareholder's interest; or (d) in partial liquidation of the corporation. A redemption that fails to qualify under any § 302 test is treated as a dividend — taxable as ordinary income to the extent of the corporation's earnings and profits, not as a capital gain.

§ 1001 — Basis Step-Up in Cross-Purchase. When an owner purchases another owner's interest through a cross-purchase structure, the purchasing owner receives a cost basis in the purchased interest equal to the purchase price paid — typically the fair market value at the time of purchase. This stepped-up basis can significantly reduce the capital gain recognized when the purchasing owner eventually sells their interest. In an entity purchase (redemption) structure, the remaining owners' interests automatically increase in percentage terms but receive no basis step-up — their basis in their own interests remains unchanged. The basis step-up advantage of cross-purchase is particularly valuable for businesses with significant unrealized appreciation where the surviving owners expect to sell in the near to medium term.

S Corporation Considerations. In S corporations, a buy-sell agreement must be drafted carefully to avoid accidentally triggering termination of the S election. An estate or trust that does not qualify as a permitted S corporation shareholder (under IRC § 1361) cannot hold S corporation stock without terminating the S election. The buy-sell agreement's buyout timeline must be short enough to ensure that ineligible shareholders hold the interest for only an incidental period — and the agreement should include a mandatory sale obligation that prevents any prohibited ownership from persisting.

Buy-sell agreements are governed primarily by state law — the law of the state where the business is formed and, in divorce and estate contexts, the law of the state where the owner is domiciled. Ten key states illustrate the range of legal environments that affect how buy-sell agreements are drafted, interpreted, and enforced.

Default Rules Without a Buy-Sell Agreement. In every state, the default rules for what happens to a business interest upon a triggering event are set by the applicable business organizations statute (LLC Act, Corporations Code, or Partnership Act). Without a buy-sell agreement, these defaults almost never produce the result the owners wanted. Most state LLC Acts provide that upon a member's withdrawal or death, the estate or transferee receives only economic rights (the right to distributions) — not management or voting rights — unless the other members agree to admit them. This can leave the estate with an economic interest but no governance rights, and the remaining owners with no obligation to buy out the interest. The resulting stalemate typically requires litigation to resolve.

Non-Compete Provisions. Buy-sell agreements often include non-competition covenants for departing owners — obligations that the departing owner will not compete with the business for a specified period and within a specified geographic area. The enforceability of these covenants varies dramatically by state. California has the most extreme position: Business and Professions Code § 16600 renders virtually all non-compete agreements unenforceable for employees and, in most cases, for owners as well (with a narrow exception for sellers of a substantial business interest). Massachusetts enacted the Noncompete Reform Act in 2018, imposing specific requirements on employee non-competes that may affect owner-level agreements as well. Florida, Texas, and Georgia have comparatively favorable non-compete enforcement environments.

Certain provisions in buy-sell agreements — whether through vague drafting, unfair economic terms, or structural design flaws — predictably produce bad outcomes when a triggering event occurs. The following eight red flags should prompt immediate review, negotiation, or redrafting before the agreement is executed.

Red Flag 1: No Defined Valuation Method — Agreement Required at Trigger Event (Critical). The clause above is the single most dangerous provision in a buy-sell agreement: no valuation method is specified, and the parties must agree on a price at the very moment when their interests are most opposed. At a death or disability trigger, the estate or disabled owner's family wants the highest possible price; the surviving owners want to pay the lowest possible price. Without a pre-determined method, the only resolution is litigation — or the threat of company dissolution that the clause above explicitly provides. Every buy-sell agreement must specify a valuation method that produces a number without requiring the parties to agree.

Red Flag 2: Stale Fixed Price Never Updated (Critical). A fixed-price provision that has not been updated in more than two years is functionally equivalent to having no valuation method. Business values change substantially — a business worth $2 million at signing may be worth $10 million five years later. A stale fixed price that produces a dramatically below-market purchase price advantages the buying owners and can expose the departing owner's estate to claims of underpayment. Courts sometimes invalidate stale fixed prices as not reflecting "adequate and full consideration" under state law, particularly in community property states where the spouse's community property interest is at stake.

Red Flag 3: Inadequate or No Insurance Funding for Death Triggers (Critical). A buy-sell agreement that requires a buyout on death but has no insurance funding in place is a financial plan that relies on the business having sufficient cash at exactly the moment when a key owner has just died and the business may be in turmoil. The absence of insurance funding means the buyout must be funded from business cash reserves or through an installment note — both of which can destabilize the business at its most vulnerable moment. Every buy-sell agreement with a death trigger should have insurance in place and should be reviewed at least annually to confirm coverage matches the current valuation.

Red Flag 4: No Definition of "Permanent Disability" or Disability Standard Tied to Unrelated Insurance Policy (High). An undefined disability standard — or one tied to a separate insurance policy that may be cancelled, amended, or expired — creates the conditions for a disputed disability determination and potential litigation at a time when one co-owner is seriously ill. Without a clinical, agreement-specific definition, each party can argue that their preferred standard applies. The resulting dispute, combined with the emotional difficulty of a disability situation, can permanently damage the co-owner relationship and the business.

Red Flag 5: No Spousal Consent Requirement in a Community Property State (High). For any owner who is married and domiciled in a community property state, failure to obtain a spousal consent leaves open the possibility that the non-owner spouse can claim an ownership interest in any buyout proceeding, override the buy-sell agreement's terms, or assert community property rights in a divorce that conflict with the agreement's transfer restrictions. This is not a theoretical concern — documented cases exist of courts in community property states declining to enforce buy-sell agreement valuations against non-consenting spouses.

Red Flag 6: No ROFR or Consent Requirement for Voluntary Transfers (High). Without a right of first refusal, consent requirement, or other transfer restriction on voluntary sales, any owner can sell their interest to a third party — a competitor, a financial buyer, or an adversarial party — without the consent of the remaining co-owners. For a closely held business where the co-owner relationship depends on mutual trust and alignment, the absence of transfer restrictions exposes the surviving owners to an unknown and potentially hostile co-owner at any time.

Red Flag 7: Installment Note with No Security or Default Acceleration (Medium). An installment note payable over five or more years, with no collateral security and no acceleration right if the company fails to make scheduled payments, provides little protection to the departing owner (or their estate). If the business struggles after the trigger event, scheduled installment payments may be missed — and without an acceleration clause or collateral, the departing owner has no leverage to enforce the payment obligation beyond a standard breach of contract lawsuit. Installment notes in buy-sell agreements should be secured by the purchased interests (or other collateral) and should include a default acceleration clause that makes the full balance due immediately upon any missed payment.

Red Flag 8: No "Good Leaver / Bad Leaver" Distinction for Voluntary Departure (Medium). A buy-sell agreement that treats all voluntary departures identically — whether the owner departs amicably after 20 years or departs in violation of a non-compete to join a competitor — misses an important incentive design. Without a good leaver/bad leaver distinction, an owner who causes significant harm to the business (by soliciting clients, poaching employees, or departing in breach of fiduciary duties) receives the same buyout price as a long-tenured owner who retires with proper notice. The absence of this distinction removes economic deterrence for harmful departures.

The FAQ section below addresses twelve of the most common questions about buy-sell agreements, covering structure selection, valuation, funding, divorce, disability, and tax treatment.

Q1: Do I really need a buy-sell agreement if I own the business with just one partner? Yes — particularly in a two-owner business, the buy-sell agreement is even more important than in a larger ownership group. With two owners, any triggering event (death, disability, bankruptcy, divorce) immediately shifts the balance of power. Without a buy-sell agreement, the surviving owner may be forced into an equal ownership arrangement with a deceased owner's estate, a disabled owner who cannot contribute, or a bankrupt owner's creditors — none of whom they chose as co-owners. The lack of a buy-sell agreement in a two-owner business is among the most common causes of forced business dissolution.

Q2: How often should a buy-sell agreement be updated? The agreement's valuation mechanism should be reviewed at least annually if a fixed price or formula is used. The entire agreement — triggers, funding mechanisms, insurance coverage amounts, and structural choices — should be reviewed any time: (1) there is a significant change in business value; (2) an owner's marital status changes; (3) the business's capital structure changes (new owners, new debt); (4) tax law changes materially affect the structure; or (5) any owner's life, disability, or buyout insurance coverage changes. Many attorneys recommend a formal annual review of buy-sell agreements as part of the business's corporate maintenance calendar.

Q3: What happens if the business does not have enough cash to fund a buyout? The buy-sell agreement should address this scenario explicitly. Common approaches: (1) life or disability insurance provides the primary funding; (2) an installment note allows payment over time; (3) the company obtains a commercial loan to fund the buyout; or (4) the buyout is delayed until the business has sufficient liquidity (subject to a stated maximum delay). Without a funding plan, the parties may face a situation where the buyout obligation exists but is economically impossible to perform, potentially requiring company dissolution to resolve.

Q4: Can a buy-sell agreement be enforced against a deceased owner's estate? Yes — a properly executed buy-sell agreement binds the owner's estate, heirs, and personal representative. The estate is typically obligated to sell the interest at the agreed price within the stated timeline. For the agreement to be enforceable against the estate, it must be properly executed before death (not on an anticipatory basis after diagnosis), must meet § 2703(b) requirements to be respected for estate tax purposes, and must have adequate funding (life insurance) to ensure the purchase price can actually be paid. Courts generally enforce buy-sell agreements against estates as long as the agreement was validly executed and the purchase price is not so far below fair market value as to constitute an unconscionable transaction.

Q5: Does a buy-sell agreement affect what my business interest is worth for estate tax purposes? Potentially, yes — but only if the agreement meets the requirements of IRC § 2703(b). A buy-sell agreement that fixes the purchase price below the business's actual fair market value will be disregarded for estate tax purposes unless it is a bona fide business arrangement, not a device to transfer property to family members for less than full consideration, and comparable to arrangements made at arm's length. If the agreement meets the § 2703(b) requirements, the agreed purchase price may also establish the estate tax value of the interest, potentially reducing estate taxes. If it does not meet these requirements, the estate tax value is determined independently of the buy-sell agreement — potentially at a much higher value.

Q6: What is a "wait-and-see" buy-sell agreement? A wait-and-see (hybrid) buy-sell agreement does not commit upfront to either an entity purchase or cross-purchase structure. Instead, when a triggering event occurs, the agreement gives the company the first option to redeem (entity purchase), then the surviving owners the second option to purchase (cross-purchase), and if neither exercises, defaults to a mandatory redemption. This structure preserves flexibility to optimize the tax treatment when the trigger event actually occurs, based on tax law, business financial condition, and the parties' circumstances at that time. The trade-off is that the decision must be made during a triggering event, which can create delay and conflict.

Q7: Can I use a buy-sell agreement to prevent my co-owner from competing with the business after they leave? Yes — a buy-sell agreement can include a non-competition covenant binding the departing owner for a specified period and within a specified geographic area. However, the enforceability of that covenant depends entirely on the state where the departing owner is domiciled and/or where the business operates. In California, non-competes are broadly unenforceable. In most other states, they are enforceable if reasonable in scope, duration, and geographic reach. Any non-compete in a buy-sell agreement should be drafted by an attorney with specific knowledge of the enforceability standards in the relevant jurisdiction.

Q8: What happens to the life insurance policy if a co-owner leaves the business? When a triggering event occurs and the buyout is completed, the insurance policy on the departing owner is no longer needed for buy-sell purposes. In an entity purchase structure, the company owns the policy and can: (1) transfer the policy to the departing owner (who can continue it as personal insurance); (2) surrender the policy for its cash value; or (3) sell the policy in the life settlement market. Be cautious about transfers — transferring a life insurance policy for valuable consideration triggers the "transfer for value" rule under IRC § 101(a)(2), making future death benefits partially taxable. In a cross-purchase structure, each owner owns their policy on the other owner's life; upon departure, the policy ownership must be explicitly addressed in the buyout documents.

Q9: What is the difference between a buy-sell agreement and a shareholder agreement? A buy-sell agreement focuses specifically on the buyout mechanism — what happens when an owner departs due to a triggering event, how the interest is valued, and how the purchase is funded. A shareholder agreement (or operating agreement for an LLC, or partnership agreement for a partnership) is a broader governance document that covers management rights, voting, capital contributions, profit distributions, fiduciary duties, and all aspects of the ownership relationship — including, in many cases, transfer restrictions and buyout provisions. In closely held businesses, the buy-sell provisions are often incorporated directly into the shareholder agreement or operating agreement rather than maintained as a separate document.

Q10: Does my buy-sell agreement need to be updated when a new owner joins the company? Yes — when a new owner is admitted to the company, several updates are needed: (1) the new owner must execute a joinder to the existing buy-sell agreement or a new agreement must be executed covering all owners; (2) the insurance requirements must be updated to include coverage on the new owner's life and disability; (3) the valuation mechanism must be reviewed to confirm it still appropriately values the business with a different ownership structure; and (4) any spousal consent must be obtained from the new owner's spouse if married. Failure to update the agreement when a new owner joins creates coverage gaps that can be extremely costly when a triggering event subsequently occurs.

Q11: Can the IRS challenge the valuation in my buy-sell agreement? Yes — under IRC § 2703, the IRS can challenge a buy-sell agreement's purchase price for estate tax purposes if the agreement does not meet the § 2703(b) safe harbor requirements. The IRS will argue that the purchase price is a "right to acquire property at a price less than fair market value" that should be disregarded in determining the estate tax value of the business interest. This challenge is most likely when: (1) the agreement is between family members (raising the question of whether it is a device to transfer property for less than full consideration); (2) the purchase price is significantly below independent appraisal value; or (3) the agreement has not been updated to reflect current business value. Annual updates and a formula or appraisal method that tracks actual fair market value substantially reduce IRC § 2703 risk.

Q12: What should I do before signing a buy-sell agreement? The essential pre-signing checklist: (1) Retain a business attorney experienced with closely held business succession planning — do not rely on a generic template; (2) Consult a tax advisor about the structural implications for estate tax, income tax on the buyout, and life insurance tax treatment; (3) Obtain a current business valuation to establish a baseline for any fixed price or formula; (4) Obtain or update life insurance and disability buyout insurance to fund the agreement; (5) Have all owners' spouses review and execute spousal consents; (6) Review any existing bank loan covenants for restrictions on redemptions or distributions that could block a buyout; (7) Confirm the agreement is consistent with the company's operating agreement or shareholder agreement; and (8) Calendar an annual review date to update the valuation and confirm insurance coverage remains adequate.
