Buy-Sell Agreement Life Insurance: The Business Owner’s Complete Guide

Most business partners spend years building something together. They negotiate equity splits, draft operating agreements, and map out growth plans — but skip the one conversation that matters most when things go wrong. What happens to your ownership interest when your partner dies?

Without a funded buy-sell agreement in place, that question gets answered in court, by creditors, or by a grieving family that has no interest in running your company. A buy-sell agreement funded with life insurance solves that problem by guaranteeing the liquidity to complete a clean ownership transition the moment a triggering event occurs.

What Is a Buy-Sell Agreement and Why Does Life Insurance Fund It?

A buy-sell agreement is a legally binding contract between co-owners of a business that establishes what happens to an owner’s interest if they die, become permanently disabled, retire, or otherwise exit. It names who can buy the departing owner’s shares, sets a valuation method for pricing those shares, and specifies how the purchase will be funded.

The funding piece is where most agreements break down. A signed agreement that says “the surviving owners will buy out the deceased’s interest” is worthless if those owners don’t have the cash to do it. Here’s how life insurance solves that problem:

• A life insurance policy is placed on each owner, with the death benefit sized to match that owner’s ownership interest in the business
• When an owner dies, the policy pays out immediately — providing liquidity at exactly the moment it’s needed
• The surviving owners or the business entity uses those proceeds to purchase the deceased’s ownership interest from their estate
• The deceased owner’s family receives a fair, pre-agreed cash payout instead of an illiquid stake in a business they can’t run
• The surviving owners retain full control of the business without involving outside parties, creditors, or probate courts

According to the U.S. Department of Labor, business succession failures are among the leading causes of closely-held business disruption — and inadequate funding is the most common preventable cause. Life insurance-funded buy-sell agreements have increased by 23% in 2025, driven in part by rising business valuations that make cash-based alternatives increasingly impractical.

Cross-Purchase vs. Entity Purchase: Which Structure Fits Your Business?

The two primary structures for a life insurance-funded buy-sell agreement are the cross-purchase agreement and the entity purchase agreement (also called a stock redemption plan). Choosing between them isn’t just a legal preference — it has real tax, administrative, and cost implications that play out over the life of the agreement.

Cross-Purchase Agreement

In a cross-purchase structure, each business owner buys and owns a life insurance policy on every other owner. The owner pays the premiums out of their own after-tax funds and is named as the beneficiary. When a co-owner dies, the surviving owner receives the death benefit directly and uses it to purchase the deceased’s ownership interest from their estate.

The cross-purchase structure works best for businesses with two to three owners. Here’s why many advisors prefer it:

• Surviving owners receive a stepped-up cost basis equal to the fair market value at the time of death, which can significantly reduce capital gains taxes on a future sale
• The death benefit is paid directly to individual owners — not to the corporate entity — avoiding Corporate Alternative Minimum Tax complications for C Corporations
• Policy ownership stays with individuals, not the business, keeping the cash value out of reach of business creditors
• Each owner maintains direct control over premium payments and policy management
• The arrangement is clean and straightforward when there are only two partners

The math gets unwieldy fast with more than three owners. Four partners require twelve separate policies. That’s twelve premium streams to track, twelve beneficiary designations to maintain, and twelve potential funding gaps if any one policy lapses.

Entity Purchase Agreement (Stock Redemption Plan)

In an entity purchase structure, the business itself buys, owns, and pays premiums on a single life insurance policy for each owner. When an owner dies, the business collects the death benefit and uses it to repurchase the deceased owner’s shares — effectively retiring those shares and increasing the remaining owners’ proportional interest.

This structure makes more sense for businesses with four or more owners, or where centralized administration is a priority:

• One policy per owner regardless of how many co-owners exist — far simpler to administer at scale
• The business pays premiums from operating cash flow, which may be more practical than requiring individual owners to fund policies personally
• Policy cash values are recorded as a business asset (which has a downside — it can increase the business’s taxable estate)
• Ownership transfers are cleaner operationally since the business handles the buyout directly
• Works well when owners have significantly different net worth profiles and some can’t afford large personal premium obligations

The tradeoff: surviving owners in an entity purchase arrangement don’t receive a stepped-up cost basis the way they would in a cross-purchase. They inherit the original basis, which increases capital gains exposure on any future sale. For businesses with low original basis and high current valuations, that’s a meaningful tax cost to model before choosing this structure.

Wait-and-See Agreement

A third option — less common but worth knowing — is the wait-and-see agreement, which combines elements of both structures. It preserves flexibility by allowing the surviving owners and the business to decide at the time of the triggering event which buyout method to use. This sounds appealing but creates complexity in policy ownership and beneficiary designations that requires careful legal drafting to execute correctly.

How to Size the Life Insurance Policy for a Buy-Sell Agreement

Getting the policy amount right is more important than any other decision in the process. Too little coverage creates a funding gap. Too much coverage wastes premium dollars and can create IRS scrutiny around valuation. The policy face amount should equal the value of each owner’s ownership interest — and that number needs to be defensible.

Here’s how our licensed advisors approach policy sizing for mid-market business owners:

• Start with a formal business valuation. For businesses with $20M to $200M in annual revenue, a qualified business appraiser should establish fair market value using a recognized methodology — EBITDA multiples, discounted cash flow, or asset-based approaches depending on the industry
• Multiply by ownership percentage. A 40% owner in a $15M business needs a $6M policy — not a round number chosen arbitrarily
• Build in a growth buffer. If the business grows 15% per year and you review the agreement every three years, the policy may need to be 40–50% larger than today’s valuation to avoid a gap at the time of death
• Review and update every two to three years. Business valuations change — especially in industries with volatile multiples like technology, energy, or financial services
• Consider permanent vs. term coverage carefully. Term life insurance is the most cost-efficient choice for buy-sell funding during active ownership years; permanent coverage (universal life or whole life) makes sense when owners are older, health-rated, or want to build cash value that can be accessed for retirement or a living buyout

One of the more common mistakes we see: a business was valued at $3M when the buy-sell was drafted in 2018, the policies were written for that amount, and the business is now worth $12M. The surviving partner technically has the right to buy out their co-owner’s estate — but only has $1.5M in insurance proceeds to fund a $6M purchase. The rest has to come from somewhere, and that somewhere is usually debt.

Tax Treatment: What Business Owners Get Right and Get Wrong

Tax questions dominate the buy-sell conversation for good reason. The structure of the agreement, who owns the policies, and who receives the proceeds all have real tax consequences that vary based on entity type and ownership structure.

Here’s what the tax picture actually looks like:

• Death benefit proceeds are generally income tax-free under IRC Section 101(a), regardless of whether the recipient is an individual owner (cross-purchase) or the business entity (entity purchase)
• Premiums are not tax-deductible — neither the business nor the individual owner can deduct buy-sell insurance premiums, which is different from key person insurance where certain deductions apply in specific structures
• C Corporations face Corporate Alternative Minimum Tax risk on life insurance death benefits received by the corporation — one reason cross-purchase structures are often preferred for C Corps
• The stepped-up basis advantage in cross-purchase agreements can be significant: a surviving owner who buys out a deceased partner’s interest at $5M using insurance proceeds receives a $5M cost basis in those shares, reducing future capital gains if the business is later sold
• The Connelly decision (2024) changed the estate valuation rules for entity purchase agreements — the IRS can now include life insurance proceeds in the value of the business for estate tax purposes, which can increase the deceased owner’s taxable estate

The Connelly ruling specifically is why several clients we work with have revisited their entity purchase structures in the past 12 months. What worked from a tax standpoint in 2020 may now create unintended estate tax exposure. If your buy-sell agreement was drafted before June 2024 and uses an entity purchase structure, it needs to be reviewed by both legal counsel and your insurance advisor.

What Happens to the Business Without a Funded Buy-Sell Agreement

Skip the planning, and here’s what actually happens when a business owner dies without a funded buy-sell agreement in place.

The deceased owner’s shares pass to their estate — and then, depending on how the estate is structured, potentially to a spouse, adult children, or a trust. Those heirs become your new business partners. They have no obligation to sell. They have no operating expertise. They have full legal rights as equity holders.

The surviving owners now face three bad options:

• Negotiate a buyout from scratch — with grieving family members, under emotional pressure, with no pre-agreed valuation, using cash the business may not have
• Liquidate business assets to raise the buyout funds — which may mean selling equipment, real estate, or accounts receivable at distressed prices during a period of operational disruption
• Take on significant debt — business loans or personal loans at interest rates that can make the buyout more expensive than the ownership interest is worth
• Continue operating with involuntary new partners who may disagree on strategy, distributions, or eventual sale terms
• Litigate — which the Small Business Administration estimates costs an average of $184,000 in legal fees for partnership disputes over succession

None of those outcomes preserve business continuity. All of them are preventable with a properly funded buy-sell agreement.

Life Insurance Options for Buy-Sell Funding: Term, Whole, and Universal

The choice of life insurance product to fund the buy-sell agreement matters for cost, flexibility, and long-term planning. These aren’t identical — and picking the wrong product type can cost business owners significantly over a 20-year ownership horizon.

Term Life Insurance

Term life is the most common choice for buy-sell funding, and for good reason. It’s the least expensive way to secure a large death benefit during the active years of business ownership. A 20-year level term policy on a 45-year-old owner in good health can be written for several million dollars at annual premiums that represent a fraction of the coverage amount.

Term works best when:

• All owners are in good health and qualify for preferred rates
• The business has a defined expected ownership horizon (e.g., planned sale in 10–15 years)
• Cash flow is the primary concern and building policy cash value is not a priority
• Owners are younger (under 55) and term coverage is still cost-efficient at the required face amounts

Permanent Life Insurance (Whole and Universal)

Permanent coverage — whether whole life or universal life — makes sense for buy-sell funding in specific situations where the higher premium cost is justified by other planning goals:

• Owners are older (55+) where term premiums at large face amounts become prohibitively expensive or uninsurable
• One or more owners has a health rating that makes term coverage expensive or unavailable
• The business intends to use the policy’s cash value as collateral, for a living buyout, or as part of a deferred compensation strategy
• The buy-sell agreement is expected to remain in place indefinitely with no planned exit horizon
• Owners want a policy that remains in force regardless of changes in health, which avoids the risk of being uninsurable at term renewal

We’ve structured buy-sell arrangements for Houston energy companies where the senior partner was 62 with a heart condition. Term coverage at the required face amount was either unavailable or priced to the point where a guaranteed universal life policy offered better long-term economics. The product selection has to match the owner’s specific situation — not a default assumption.

Don’t Forget Disability: The Trigger That Life Insurance Doesn’t Cover

Here’s the gap most business owners miss: life insurance only triggers on death. A business partner who suffers a severe stroke at 54 — permanently disabled, unable to work, still a 50% equity stakeholder — creates the same ownership crisis as a death, but the life insurance policy pays nothing.

Disability buyout insurance solves this. A separate policy — structured to align with the buy-sell agreement — pays out a lump sum or monthly benefit after a defined elimination period (typically 12 to 24 months) to fund the purchase of the disabled owner’s interest. Key features to know:

• Elimination periods are long by design — temporary disability doesn’t trigger a buyout, which protects the disabled owner’s interest during recovery
• The definition of “total disability” in the policy must match the trigger language in the buy-sell agreement — misalignment between the two documents is a common structuring error
• Disability buyout policies are typically limited to $3M to $5M in coverage per owner depending on the carrier and the business’s financial statements
• Premiums are generally not tax-deductible, but benefits received are typically tax-free when the employee pays the premium
• Coverage becomes harder to obtain as owners age — securing disability buyout coverage in the 40s is significantly easier and cheaper than trying to structure it at 58

A complete business succession plan addresses both triggers — death and disability — with coordinated insurance that ensures the surviving owners can complete the buyout regardless of how the triggering event occurs.

How to Keep Your Buy-Sell Agreement Current

A buy-sell agreement that isn’t reviewed regularly becomes a liability. Business valuations change. Ownership percentages shift. Partners age out of term coverage. Tax laws evolve — the Connelly decision being the most recent example of a ruling that required immediate review for thousands of entity purchase agreements.

Our standard recommendation for business owners running $20M or more in revenue:

• Review the business valuation and policy amounts every two years — more frequently in high-growth phases or after a major acquisition, contract win, or market shift
• Verify that all policy premiums are current — a lapsed policy creates a funding gap that isn’t discovered until it’s too late
• Confirm beneficiary designations match the agreement structure — ownership transfers, divorces, or estate plan changes can inadvertently misalign who receives the death benefit
• Review the agreement language after any ownership change — adding a new partner, buying out a partial interest, or bringing in investors may require revisions to the valuation methodology or triggering event definitions
• Audit for tax law changes annually — the Connelly ruling, SECURE Act provisions, and potential future changes to the estate tax exemption all have downstream implications for buy-sell structures
