Buy-Sell Agreement Funding
How to Fund a Buy-Sell Agreement: Life Insurance and the Alternatives
Published October 8, 2026 · Updated October 9, 2026
Short Answer: How a Buy-Sell Agreement Gets Funded
A buy-sell agreement obligates someone to buy a departing or deceased owner's interest, but it does not supply the money. That money usually comes from life insurance on each owner, a sinking fund of accumulated cash, installment payments over time, or a loan, used alone or in combination.
Co-owners of closely held businesses often reach this question after the agreement is drafted, when they see the purchase price sitting unfunded. Life insurance is frequently used for the death trigger because it pays a lump sum when the obligation arises. This page weighs that funding decision. The insurance-funded arrangement itself is explained on the site's page on buy-sell life insurance.
The Planning Objective: Why Funding Matters
Every buy-sell agreement carries a promise to pay. The agreement is a contract among co-owners, or between the owners and the business entity, that obligates a buyer to purchase and a seller or the seller's estate to sell an ownership interest on a triggering event, such as death, disability, retirement or voluntary departure.
The agreement sets the price, or a method for finding it, such as a fixed price, an appraisal or an earnings formula. It does not create the cash. Without funding arranged in advance, surviving owners or the entity must find a large sum quickly, often while the business is absorbing the loss of an owner. If they cannot, the deceased owner's estate may remain an unwanted co-owner.
The mechanism chosen affects the business's cash flow, the owners' personal balance sheets and the tax treatment of premiums and proceeds. This page concentrates on the agreement's death or exit purchase. Lifetime transitions, such as retirement or a sale to the next generation, belong to succession funding, covered in the site's material on business succession life insurance.
How the Structure Works: Matching Funding to the Obligation
Funding is arranged before the triggering event so that money exists when the purchase falls due, without forced asset sales or short-notice borrowing. Each approach differs in who holds the asset and when it pays.
Life insurance. A policy is issued on each owner's life. The death benefit is paid to the named beneficiary, ordinarily the policy owner: the surviving co-owners under a cross-purchase structure, or the entity under an entity-purchase (redemption) structure. Those proceeds then pay the purchase price to the estate.
Sinking fund. The business or the owners set aside cash periodically in a dedicated account. The balance builds over time but may fall short if an owner dies early, and cash held by the business may be exposed to the business's creditors.
Installment payments. The buyer pays the price over time from future earnings. The estate receives a stream of payments rather than a lump sum, and the obligation stays on the buyer's books until paid.
Which structure applies, and therefore who owns each policy, is a separate question addressed on the site's cross-purchase versus entity-purchase page.
Parties Involved in a Funded Buy-Sell Arrangement
Four roles appear in any insurance-funded buy-sell: the insured, the policy owner, the premium payer and the beneficiary. The insured is each owner whose life is covered. The policy owner controls the contract. The beneficiary receives the death benefit, and in buy-sell funding the owner and beneficiary are usually the same party.
In a cross-purchase structure, each owner owns, pays for and is the beneficiary of a policy on each other owner's life. In an entity-purchase structure, the business owns, pays for and is the beneficiary of a policy on each owner. The site's page on cross-purchase buy-sell agreements describes the first in detail, and the roles in general are set out in how business life insurance works.
Ownership and beneficiary choices drive the income-tax treatment of the death benefit under 26 U.S.C. § 101(a)(1) and whether the employer-owned contract rules of 26 U.S.C. § 101(j) apply. IRS Notice 2009-48 states that a contract "owned by the owner of an entity engaged in a trade or business (such as for purposes of financing the purchase of an equity interest of another owner)" is not an employer-owned contract (A-1), while ownership "by a partnership or sole proprietorship does not prevent the contract from being treated as an employer-owned life insurance contract" (A-3) when the contract is otherwise described in § 101(j)(3).
The agreement names the price, valuation method and triggering events; the funding is coordinated with it but is a separate arrangement. Insurance rules on who may own a policy and on beneficiary designations vary by state.
Who This Page Is For
The intended reader is a co-owner of a closely held business, whether a partnership, an LLC, an S corporation, a C corporation or a professional practice, who has or is drafting a buy-sell agreement and is weighing how to fund the purchase obligation. Finance leads, CFOs and advisers coordinating the funding decision with the agreement's drafting may also find it relevant. A law firm, for example, faces the same decision, discussed on the site's page on life insurance for law firms.
This page is not a guide to drafting the agreement, to choosing between cross-purchase and entity-purchase structures, or to buying personal life insurance. A sole proprietor generally has no co-owner to buy the business under a buy-sell agreement, though succession or key-person planning may still apply.
When Life Insurance Funding May Fit
Death is the trigger that life insurance matches most directly, because the death benefit is payable when the purchase obligation arises. Insurance is commonly considered where a lump sum at death matters. Examples include an estate that needs liquidity promptly, a business that cannot carry a long installment obligation, and surviving owners who cannot fund the price from personal assets.
Permanent life insurance, such as whole life or universal life, includes cash value as a contract feature.
Several facts shape whether and how coverage can match the obligation. These include the number of owners, their relative ages and health, and the agreement's valuation method. Because the coverage amount has to track the agreed purchase price, business valuation for buy-sell funding is a topic that needs individual review of the agreement and contracts involved, by the insurers and a qualified tax professional.

When Life Insurance Funding May Not Fit
Insurance depends on underwriting. An owner who is uninsurable, or whose health makes coverage very costly, may leave a gap that insurance cannot close.
With many owners, a cross-purchase structure ordinarily has each owner hold a separate policy on every other owner, which is n × (n − 1) policies for n owners. The policy count rises quickly and so does administration.
Some agreements are driven mainly by triggers other than death, such as disability, retirement or voluntary departure. Life insurance alone does not fund those events, so disability coverage or another mechanism may be paired with it.
Value growth creates another mismatch. If the business grows significantly after the policies are issued, the death benefit may no longer cover the full price, which is why these arrangements are generally revisited over time.
Where insurance is unavailable, or the owners prefer not to carry ongoing premiums, a sinking fund, installments or a loan may be weighed, each with its own trade-offs.
Tax Treatment of Life Insurance Proceeds Used to Fund a Buy-Sell
The starting point is 26 U.S.C. § 101(a)(1), which provides that, with stated exceptions, "gross income does not include amounts received (whether in a single sum or otherwise) under a life insurance contract, if such amounts are paid by reason of the death of the insured."
Premiums are a separate matter. 26 U.S.C. § 264(a)(1) provides that no deduction is allowed for "premiums on any life insurance policy ... if the taxpayer is directly or indirectly a beneficiary under the policy." In buy-sell funding, the premium payer is ordinarily the beneficiary, whether that payer is the entity or a co-owner.
Transfer for value. Under 26 U.S.C. § 101(a)(2), when a contract is transferred "for a valuable consideration," the exclusion "shall not exceed" the actual value of the consideration plus "the premiums and other amounts subsequently paid by the transferee." The limit does not apply to a transfer where the transferee's basis is determined in whole or part by the transferor's basis. It also does not apply to a transfer "to the insured, to a partner of the insured, to a partnership in which the insured is a partner, or to a corporation in which the insured is a shareholder or officer." Those exceptions are themselves unavailable for a reportable policy sale under § 101(a)(3). A co-shareholder is not on that list.
Employer-owned contracts. Under 26 U.S.C. § 101(j)(1), the exclusion for an employer-owned contract generally "shall not exceed" the premiums and other amounts paid. The cap is lifted only when a § 101(j)(2) exception applies and the § 101(j)(4) written notice and consent were given before the contract was issued; neither alone is enough. The exceptions cover an insured who was an employee within the 12 months before death, or who was a director or highly compensated employee or individual when the contract was issued. They also cover amounts paid to the insured's family, designated beneficiary, a trust for them or the estate, or "used to purchase an equity (or capital or profits) interest in the applicable policyholder" from those persons. Notice 2009-48, A-5, adds that "employee" includes an officer, director and highly compensated employee.
How proceeds used for the purchase are treated, and the buyer's resulting basis in the acquired interest, depend on the structure and facts. Transfers of policies between owners, § 101(j) notice, consent and reporting, and estate-tax valuation of the interest each need individual review of the contracts involved, by the insurers and a qualified tax professional. Sinking funds, installments and loans carry their own tax consequences, which § 101(a) and § 264 do not address.
Potential Advantages of Insurance-Funded Buy-Sell Agreements
Four features of the mechanism are commonly cited, each described in general terms.
Treatment of proceeds. Section 101(a)(1) provides the general exclusion of death proceeds from gross income, subject to the transfer-for-value and § 101(j) limits. Whether a given arrangement falls within it turns on its facts.
Liquidity at the event. The death benefit becomes payable when the triggering event occurs. The purchase can then proceed without selling other assets or borrowing.
A known amount. The face amount is set by the contract. The funding figure is therefore known in advance, though it still has to be kept in line with the business's value.
Cash value. A permanent policy's cash value is a contract feature that may be accessible during the owners' lifetimes under the policy's terms.
Whether any of these applies to a particular arrangement depends on the policy, the structure and the facts.
Important Considerations Before Funding a Buy-Sell with Life Insurance
Coordination is where funded arrangements most often break down. The coverage amount is tied to the agreement's valuation method, and under a fixed-price agreement it is generally revisited whenever the business's value changes materially. Valuation itself is confirmed with a qualified tax professional.
The agreement and the policies work as one system. A mismatch between the agreement's terms and a policy's owner, beneficiary designation or face amount can leave the purchase unfunded or funded to the wrong party.
Replacing or exchanging an existing policy to fund the agreement may involve a policy exchange, which the site treats on its own page; a change in policy ownership between owners also raises transfer-for-value questions under § 101(a)(2).
Insurance rules, including who may own a policy, permissible beneficiary designations and free-look periods, vary by state and are confirmed with the insurers involved. The number of policies, the premiums and the administrative load vary with the structure and the number of owners; the factors behind premiums appear on the site's page on business life insurance cost.
Tax and Legal Coordination
At least three bodies of law meet in a funded buy-sell. Contract law governs the agreement. Federal income-tax law governs the policies through § 101(a), § 101(a)(2), § 101(j) and § 264. State insurance law governs the contracts themselves.
The agreement is a legal document requiring legal drafting, and its terms are matched to each policy's ownership, beneficiary and proceeds.
Estate tax adds a further layer. Under 26 U.S.C. § 2703(a), value is generally determined "without regard to" an option or agreement to acquire property below fair market value, or a restriction on its sale. Section 2703(b) lifts that rule only for an agreement that is "a bona fide business arrangement," is "not a device to transfer such property to members of the decedent's family for less than full and adequate consideration," and has terms "comparable to similar arrangements entered into by persons in an arms' length transaction."
Reporting can apply too. 26 U.S.C. § 6039I requires every applicable policyholder owning employer-owned contracts issued after its enactment to file an annual return, including whether it "has a valid consent for each insured employee." Whether a buy-sell policy is employer-owned depends on § 101(j) and Notice 2009-48. Structure, ownership and tax treatment are generally confirmed with qualified tax, legal and insurance professionals before the agreement is signed and the policies are issued.
Alternatives to Life Insurance Funding
Insurance is one of several buy-sell funding options, and each alternative trades certainty for a different cost.
Sinking fund. Where a death benefit is fixed from the start, the amount available from a sinking fund depends on how long it has been building when the trigger occurs, and it may be exposed to the business's creditors.
Installment payments. In place of a lump sum, the estate's payments depend on the buyer's future earnings, and the buyer carries the obligation for the full payment period.
Bank loan or line of credit. The buyer borrows at the triggering event. Availability depends on creditworthiness at that moment, often just after an owner's death, and debt service is added to the business's obligations.
Each alternative has its own cash-flow, credit and tax consequences, and their tax treatment is confirmed with a qualified tax professional. Combinations are common, for example life insurance for the death trigger and an installment note for disability or retirement, and the combination has to match the agreement's terms.
Example (Hypothetical): Comparing Funding Approaches for a Two-Owner Business
This example is hypothetical, and every figure in it is a round number chosen for illustration. Two equal owners each hold an interest worth $1,000,000, and no growth, interest or premium amounts are modeled.
Life insurance (cross-purchase). Each owner owns a $1,000,000 policy on the other. At the first death, the survivor receives $1,000,000. Section 101(a)(1) generally excludes that amount from gross income, subject to the § 101(a)(2) and § 101(j) limits. The survivor pays $1,000,000 to the estate for the interest.
- Proceeds $1,000,000 − purchase price $1,000,000 = $0 gap.
Sinking fund. The business adds an illustrative $50,000 a year to a dedicated account.
- $50,000 × 20 years = $1,000,000 at full funding.
- If death occurs in year 5: $50,000 × 5 = $250,000 accumulated.
- $1,000,000 − $250,000 = $750,000 still to be funded another way.
Installments. The survivor pays the estate over 10 years.
- $1,000,000 ÷ 10 = $100,000 per year.
- The estate receives payments over a decade, and the obligation stays on the survivor's books throughout.
The figures are round numbers for illustration only. Actual premiums, fund growth and tax consequences depend on specific facts, and nothing here is a coverage recommendation.

Frequently Asked Questions
What are the main ways to fund a buy-sell agreement?
The main approaches are life insurance on each owner, a sinking fund of accumulated cash, installment payments over time, and a bank loan or line of credit. Insurance pays at death, a sinking fund builds gradually, installments spread the price over future earnings, and a loan depends on credit at the event. Arrangements often combine approaches.
Is the life insurance death benefit taxable when it is used to fund a buy-sell purchase?
Section 101(a)(1) generally excludes death proceeds from gross income. The exclusion can be limited by the transfer-for-value rule in § 101(a)(2) and, for employer-owned contracts, by the § 101(j) cap. That cap lifts only when an exception applies and written notice and consent preceded issuance. The result depends on structure and facts.
What is the transfer-for-value rule and how does it affect buy-sell funding?
Under § 101(a)(2), a transfer of a policy for valuable consideration limits the exclusion to the actual value of the consideration plus later premiums and other amounts paid. Exceptions include carryover-basis transfers and transfers to the insured, a partner of the insured, a partnership in which the insured is a partner, or a corporation in which the insured is a shareholder or officer.
Does a buy-sell agreement funded with life insurance affect the estate-tax value of the business interest?
It can. Under 26 U.S.C. § 2703(a), value is generally determined without regard to an agreement to acquire property at a price below fair market value, or a restriction on its sale. The exception requires a bona fide business arrangement, no device to transfer property to family below full consideration, and terms comparable to arm's-length arrangements. Whether an agreement meets those tests is a fact-specific question for a qualified tax professional.
What happens if the life insurance coverage amount no longer matches the business's value?
The death benefit may then fall short of the purchase price, leaving a gap the buyer must fund another way. Arrangements are generally revisited as value changes and kept aligned with the valuation method. Replacing or exchanging a policy is a separate exchange question, and ownership changes raise transfer-for-value questions.
Is a policy owned by a business entity to fund a buy-sell agreement an employer-owned life insurance contract?
It may be. Notice 2009-48, A-1, says a contract owned by the owner of an entity engaged in a trade or business, such as to finance buying another owner's interest, is not employer-owned. A-3 says partnership ownership does not prevent a contract otherwise described in § 101(j)(3) from being employer-owned. An entity-owned policy is tested under § 101(j)(3), and the answer depends on the specific arrangement.
Can a sinking fund replace life insurance as buy-sell funding?
A sinking fund can fund the purchase, but only to the extent of its balance when the trigger occurs. An early death may leave a shortfall. The fund is a business asset that may be exposed to creditors, and its tax treatment is a separate question for a qualified tax professional.
