What a Buy-Sell Agreement Does
A buy-sell agreement is a binding contract among co-owners of a business — or between the owners and the business entity itself — that governs what happens to an ownership interest when a specified triggering event occurs. It answers the question that no operating agreement or shareholder agreement automatically resolves: when an owner leaves, who buys the interest, at what price, and on what terms?
The agreement works in two directions at once. It protects the departing owner's family by guaranteeing a buyer and a price for an asset that is otherwise illiquid. And it protects the remaining owners by preventing a business interest from landing in the hands of someone who cannot contribute — or who may actively disrupt operations.
What happens without one. Two partners own a Utah construction company equally. One dies unexpectedly at 51. His ownership interest passes under his will to his wife, who has no construction experience and no desire to run a business. She is now a 50% owner. The surviving partner has no legal obligation to buy her out, and no agreed price if he wanted to. She cannot sell to anyone else without his consent. He cannot buy her out without her agreement on price.
Both parties are stuck — the widow with an illiquid asset generating conflict instead of income, and the surviving partner running a business with an involuntary co-owner. A buy-sell agreement signed years earlier would have resolved this the moment the death certificate was issued.
Triggering Events
A well-drafted buy-sell agreement addresses more than just death. The full range of events that should trigger a buyout or transfer restriction includes:
- Death — the most commonly addressed trigger, and often the one funded by life insurance
- Long-term disability — frequently overlooked, even though disability is statistically more likely than death at working age
- Retirement or voluntary exit — when an owner wants to cash out and move on
- Divorce — prevents an owner's ex-spouse from acquiring an interest through a property settlement
- Bankruptcy or creditor seizure — prevents a creditor from stepping into the ownership position
- Termination of employment — when an owner-employee is removed or resigns
- Irreconcilable deadlock — provides an exit mechanism when owners cannot agree
Many buy-sell agreements address only death and leave the other triggers to chance. That is a significant gap — and one that tends to surface at the worst possible moment.
The Three Main Structures
Cross-Purchase Agreement
In a cross-purchase agreement, the surviving owners personally agree to purchase the departing owner's interest. Each owner holds life insurance on the other owners to fund the death trigger. When an owner dies, the surviving owners collect the life insurance proceeds and use them to buy the deceased owner's interest from the estate.
The primary advantage of the cross-purchase structure is the tax treatment for the surviving owners. Because they purchase the interest directly, their cost basis in the business steps up to the purchase price — which reduces the taxable gain when they later sell their own interests.
The disadvantage is complexity. With three owners, each holds a policy on the other two — that is six policies to purchase, maintain, and keep funded as the business grows. With more than three owners, the web of policies becomes unwieldy.
Entity-Redemption Agreement
In an entity-redemption agreement, the business itself agrees to buy back the departing owner's interest. The business holds life insurance on each owner to fund the death trigger. When an owner dies, the business collects the proceeds and redeems the interest from the estate.
This structure is simpler to administer — one policy per owner, held and paid for by the entity. It works well when there are many owners, when ownership percentages shift frequently, or when owners prefer not to manage individual policies on each other.
The trade-off is that surviving owners do not get a basis step-up. Their percentage ownership increases after the redemption, but their cost basis in the business does not, which can mean a larger taxable gain on a future sale.
Hybrid (Wait-and-See) Agreement
A hybrid agreement gives the entity a first right to purchase the departing owner's interest, followed by the remaining owners if the entity declines — or the reverse. This structure preserves flexibility to choose the more favorable tax treatment at the time of the actual triggering event, rather than committing in advance.
It is a reasonable choice when owners are uncertain which structure will be more advantageous at a future date, or when tax laws are likely to change.
| Structure | Who Buys | Who Holds Insurance | Best For | Basis Step-Up |
|---|---|---|---|---|
| Cross-Purchase | Individual owners | Each owner (on the others) | 2–3 owners | Yes |
| Entity Redemption | The business | The business | 4+ owners | No |
| Hybrid | Entity first, owners second (or reverse) | The business | When flexibility is valued | Depends on who exercises |
Funding the Agreement: Life Insurance
A buy-sell agreement is only as good as the money available to execute it. The most common funding mechanism for the death trigger is life insurance — because the event that creates the obligation also generates the cash to meet it.
The life insurance policy is purchased in an amount equal to the estimated value of the owner's interest. When the owner dies, the policy pays out and the proceeds are used to complete the purchase. The family receives cash. The business gets clear title to the interest.
Without life insurance funding, a buyout at death may require the surviving owners to borrow, or the business to liquidate assets, at exactly the moment it can least afford to. Installment payments to the estate over several years are an alternative, but they extend uncertainty and create ongoing obligations that can strain the business.
Keep coverage current. A life insurance policy purchased when the business was worth $500,000 does not fund a buyout if the business is now worth $2 million. Insurance coverage should be reviewed every one to three years — or after any major change in the business's value — to ensure it keeps pace with growth.
Valuation: Setting the Price
The most common point of failure in buy-sell agreements is valuation. The agreement must specify not just that a buyout will occur, but at what price. The three main approaches are:
Fixed price
The owners agree on a specific dollar amount for the entire business or for each ownership interest. This is simple, but it becomes outdated quickly. A fixed price set when the business was founded may bear no relationship to what the business is worth five or ten years later. Most agreements with fixed pricing include a requirement to update the number annually — and most owners neglect to do so.
Formula-based valuation
The agreement specifies a formula — a multiple of revenue, a multiple of EBITDA, or book value — that will be applied at the time of the triggering event. This approach stays current automatically because it is calculated from actual financial results. Its weakness is that any formula can produce results that feel unfair in specific circumstances that nobody anticipated when the formula was written.
Independent appraisal
The parties agree that a qualified business appraiser will value the business at the time of the triggering event. This is the most accurate approach and the most defensible — but also the most expensive and the slowest. It can delay a buyout when time is critical.
A hybrid approach — a formula as the default, with an appraisal option if either party disputes the result — is common in well-drafted agreements.
The Estate Tax Dimension
A buy-sell agreement that meets the requirements of IRC § 2703 can establish a binding value for the business interest for federal estate tax purposes. If the agreement qualifies, the IRS is generally bound to the agreed-upon price when calculating the taxable estate.
To qualify under § 2703, the agreement must satisfy three conditions: it must be a bona fide business arrangement, it must not be a device to transfer wealth to family members at a discount, and its terms must be comparable to what parties dealing at arm's length would agree to. An agreement designed primarily to reduce estate taxes — rather than to serve the legitimate business purpose of controlling ownership — risks being disregarded by the IRS, which would then impose its own, potentially much higher, valuation.
The estate tax implications are significant enough that buy-sell agreements among family members receive heightened IRS scrutiny. An agreement between a parent and children who are co-owners will be examined more carefully than one between unrelated business partners.

Even business owners who have a buy-sell agreement in place often have one that will fail when tested. The most frequent problems:
- Addressing only death. Disability, divorce, and deadlock are statistically more likely to trigger a buyout than death. An agreement that covers only one trigger leaves significant gaps.
- Stale valuation. A fixed price written years ago — and never updated — will produce a result that one side finds deeply unfair. Annual price updates should be built into the agreement as a mandatory obligation.
- Underfunded life insurance. Coverage that has not kept pace with business growth will require the business or surviving owners to come up with the difference from other sources, often under time pressure.
- No coordination with the estate plan. A buy-sell agreement that directs proceeds to the estate must be consistent with the will or trust that distributes the estate. Conflicts between the two documents create exactly the kind of confusion they were both designed to prevent.
- Not addressing the disability trigger. Long-term disability is more common than death among working-age business owners. An owner who cannot work but retains full ownership rights can paralyze a business without any mechanism for the other owners to act.
- Using a cross-purchase structure with many owners. Three owners require six policies. Four require twelve. The administrative burden becomes unmanageable and policies often lapse or are allowed to fall behind.
A handshake agreement is not a buy-sell agreement. Many business partners have discussed what would happen if one of them died, reached an informal understanding, and moved on without putting anything in writing. That understanding is legally unenforceable. It will not bind the estate, and it will not bind a surviving spouse who has different ideas. The conversation is a starting point, not a substitute for the document.
Coordinating with Your Estate Plan
A buy-sell agreement does not stand alone. It is one piece of a larger picture that includes your will or trust, any life insurance held inside an irrevocable life insurance trust, beneficiary designations on retirement accounts, and any operating agreement or shareholder agreement governing the business entity.
These documents need to be consistent with each other. A will that leaves a business interest to your spouse cannot override a buy-sell agreement that requires the interest to be sold — but the conflict will create confusion, delay, and legal expense if the two documents are not drafted with each other in mind. Getting them right requires the attorneys who draft them to be working from the same understanding of what you want.
Frequently Asked Questions
-
A buy-sell agreement in the traditional sense requires multiple owners, since it governs transfers between them. If you are a sole owner, the relevant documents are your will or trust (which determines who inherits the business) and a business succession plan (which determines what happens operationally). If you bring on a co-owner in the future, a buy-sell agreement should be executed at that time.
-
In a cross-purchase agreement, the surviving owners personally buy the departing owner's interest. Each owner holds life insurance on the others to fund their individual purchase obligations. In an entity-redemption agreement, the business itself buys back the interest, and the business holds the life insurance policies. Cross-purchase agreements work best with two or three owners; entity-redemption is simpler when there are many owners. Each structure has different income tax and estate tax implications.
-
A properly structured buy-sell agreement can establish a defensible valuation for federal estate tax purposes under IRC § 2703. To qualify, the agreement must be a bona fide business arrangement, must not be a device to transfer value to family members for less than full consideration, and its terms must be comparable to similar arrangements entered at arm's length. An agreement that meets these requirements generally binds the IRS to the agreed-upon price. An agreement that fails to meet them may be disregarded, and the IRS can impose its own valuation.
-
At minimum, the valuation should be reviewed every one to three years, or after any significant change in the business — a major new contract, a substantial increase in revenue, the addition of new owners, or a change in the business structure. Many agreements with a fixed-price valuation method become dangerously outdated within a few years of signing. Life insurance coverage amounts should be updated in parallel to keep pace with any increase in the business's value.
-
Your partner's ownership interest passes to their estate and then to their heirs — typically a surviving spouse or children. Those heirs become your new co-owners, whether either party wants that outcome or not. They may have no interest in or ability to run the business, but they have the same ownership rights as your former partner. Without a buy-sell agreement establishing a price and an obligation to sell, there is no mechanism to force a buyout and no guaranteed source of funds to pay for one.
