Key Person Insurance vs Buy-Sell Insurance: Different Purposes, Owners and Beneficiaries
Published October 9, 2026 · Updated October 9, 2026
Short Answer: Two Policies, Two Different Business Problems
Key person insurance and buy-sell insurance solve different business problems. With key person insurance, the business owns the policy, pays the premiums and receives the death benefit to absorb the financial loss of a critical individual. Buy-sell insurance funds a written agreement to buy a deceased owner's interest, and the policy is owned by the business or by the co-owners, depending on how the agreement is structured.
Owners, partners and finance leads of closely held companies often weigh key person vs buy-sell insurance together, because one protects operations and the other protects ownership. A business may use both, one or neither, depending on its structure and goals. Business Life Insurance compares purpose, ownership, beneficiary and federal tax treatment side by side.
At-a-Glance Comparison: Key Person Insurance vs Buy-Sell Insurance
| Criterion | Key person insurance | Buy-sell insurance |
|---|---|---|
| Business problem solved | Financial loss from the death of a critical individual | Funding the purchase of a deceased owner's interest |
| Who owns the policy | The business | The business (entity purchase) or each co-owner (cross-purchase) |
| Who pays the premiums | The business | The policy owner: the business or each co-owner |
| Who is the beneficiary | The business | The policy owner: the business or the surviving co-owner |
| How proceeds are used | Kept in the business for operations, recruiting, stabilization | Paid toward the purchase price under the agreement |
| Premium deductibility, 26 U.S.C. § 264(a)(1) | No deduction where the taxpayer is directly or indirectly a beneficiary | Same rule for both structures |
| Death benefit, 26 U.S.C. § 101(a)(1) and § 101(j) | General exclusion; § 101(j) cap may apply to employer-owned contracts | Entity purchase: § 101(j) may apply; under Notice 2009-48 A-1, a contract owned by an entity's owner "for purposes of financing the purchase of an equity interest of another owner" is not employer-owned |
| Transfer for value, 26 U.S.C. § 101(a)(2) | Arises if the policy is transferred for consideration | Often relevant when policies move between owners or the entity |
| Separate legal agreement | Not required for the policy itself | A buy-sell agreement exists apart from the policy |
| Typical business entities | Any form that depends on one or more individuals | Businesses with two or more owners |
Section 264(a)(1) of the Internal Revenue Code denies a premium deduction "if the taxpayer is directly or indirectly a beneficiary," and it reaches both arrangements. Under section 101(j), the exclusion for an employer-owned contract may be capped unless a statutory exception and the written notice-and-consent requirements are both met. The table summarizes general rules; actual results turn on each contract's facts.
Key Person Insurance: Protecting the Business Against the Loss of a Critical Individual
Some businesses depend on one person's sales, clients or technical skill, and losing that person can cut revenue before a successor is in place. Key person insurance (also called key man or key employee insurance) is a life insurance policy the business owns on the life of an individual whose death would cause measurable financial harm to the business. The business is the owner, the premium payer and the beneficiary. The insured is the key individual. The proceeds go to the business to offset lost revenue, pay for recruiting and training, or stabilize operations. They do not transfer ownership. The mechanics are explained in more detail on the page about how key person insurance works.
Two federal rules frame the arrangement. Under 26 U.S.C. § 264(a)(1), "No deduction shall be allowed for" premiums on a life insurance policy "if the taxpayer is directly or indirectly a beneficiary under the policy." Because the business owns the policy and is its beneficiary, a key person policy on an employee is generally an employer-owned life insurance contract under 26 U.S.C. § 101(j)(3). For such a contract, section 101(j)(1) limits the excluded amount to "the sum of the premiums and other amounts paid by the policyholder for the contract." The cap is lifted only if a section 101(j)(2) exception applies and the section 101(j)(4) notice and consent were given before the contract was issued. Notice and consent alone do not lift the cap, and neither does an exception alone.
Notice 2009-48 also addresses these points in its answers. A contract owned by the owner of an entity, "such as for purposes of financing the purchase of an equity interest of another owner," is not an employer-owned contract (A-1). For a contract otherwise described in section 101(j)(3), ownership by a partnership or sole proprietorship "does not prevent the contract from being treated as" one (A-3). "Employee" includes "an officer, director, and highly compensated employee" (A-5).
Buy-Sell Insurance: Funding an Ownership Transfer
When an owner dies, the surviving owners, the business and the estate all face a question about who now holds that interest and how it is paid for. A buy-sell agreement is a legally binding contract that governs what happens to an owner's interest when that owner dies, becomes disabled or leaves the business. Buy-sell insurance is life insurance that provides the money to buy the deceased owner's interest at the agreed price or formula. The agreement is the plan. The policy is only the funding mechanism.
There are two main structures. In an entity purchase (also called a redemption), the business owns a policy on each owner, is its beneficiary, and buys back the interest. In a cross-purchase, each owner owns a policy on the other owners, pays its premiums, is its beneficiary, and buys the interest directly. The cross-purchase versus entity purchase choice is a separate topic. The page on how buy-sell life insurance works walks through what happens at an owner's death.
Section 264(a)(1) applies to both structures. Section 101(a)(1) provides that gross income "does not include amounts received ... under a life insurance contract, if such amounts are paid by reason of the death of the insured." In an entity purchase, section 101(j) may apply, with the same exception and notice-and-consent conditions as key person insurance. One exception, in section 101(j)(2)(B)(ii), covers amounts "used to purchase an equity (or capital or profits) interest in the applicable policyholder" from the insured's family members, designated beneficiary, trust or estate.
Section 101(a)(2), the transfer-for-value rule, limits the exclusion for a policy transferred "for a valuable consideration" to the consideration paid plus later premiums and other amounts, with exceptions. Policy transfers between co-owners in a restructuring, and the business valuation behind the price, need individual review of the contracts and agreement involved by a qualified tax professional.
In Connelly v. United States (2024), a case about valuing shares for the federal estate tax, the Supreme Court observed, of the brothers in that case, that a cross-purchase "would have required each brother to pay the premiums for the insurance policy on the other brother, creating a risk that one of them would be unable to do so." The Court also noted that "every arrangement has its own drawbacks." The holding was that the corporation's contractual obligation to redeem the deceased shareholder's shares did not diminish the value of those shares.
Key Differences: Purpose, Ownership and What the Proceeds Do
Purpose is the clearest dividing line. Key person insurance addresses operating and financial risk from losing a critical employee or owner. Buy-sell insurance addresses ownership continuity and the cash needed when a triggering event occurs.
- Where proceeds go. Key person proceeds stay in the business for operating use. Buy-sell proceeds pay for an ownership interest, which passes to the surviving owners or to the entity.
- The insured's role. A key person need not be an owner. A buy-sell insured is always an owner whose interest is being bought.
- The legal agreement. A key person policy needs no separate agreement. Buy-sell insurance funds an agreement that exists on its own.
- How the amount is set. A buy-sell agreement typically sets a price by a fixed figure, a formula or an appraisal; the page on business valuation for buy-sell agreements covers how that clause works. A key person amount reflects the estimated financial loss to the business. Both depend on the business's own facts.
Because the two solve different problems, a business may hold both at once, for example a key person policy on a non-owner executive and a buy-sell policy on each owner.
Tax Treatment Compared: Section 264, Section 101(a) and Section 101(j)
The federal income-tax rules fall into three questions: how section 264(a)(1) treats premiums, how the death benefit is treated, and what happens if the policy changes hands.
Premiums. 26 U.S.C. § 264(a)(1) denies a deduction for premiums "if the taxpayer is directly or indirectly a beneficiary under the policy." This covers key person policies and entity-purchase policies. In a cross-purchase, each co-owner pays premiums on a policy that co-owner owns and benefits from, so the same rule applies. The page on the deduction question for key person premiums explains this rule further.
Death benefit. Section 101(a)(1) states the general exclusion. For an employer-owned contract, section 101(j)(1) caps that exclusion at premiums and other amounts paid. The cap is lifted only when both conditions are met:
- an exception applies, based either on the insured's status (an employee at any time during the 12-month period before death, or at issue a director, a highly compensated employee or a highly compensated individual) or on amounts paid to the insured's heirs; and
- before issuance, the employee was notified in writing of the intent to insure and the maximum face amount, gave written consent (including consent that coverage may continue after employment ends), and was told in writing that the policyholder will be a beneficiary.
The cap can apply to key person policies and entity-purchase policies. Under Notice 2009-48 A-1, a contract an owner holds to finance buying another owner's interest is not an employer-owned contract. The page on key person insurance tax treatment discusses Form 8925 reporting.
Transfers. Section 101(a)(2) excepts transfers "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," and transfers with a carryover basis. A co-shareholder is not on that list.
State income-tax treatment varies; Business Life Insurance addresses federal rules only.

Who This Is For: Businesses That Use One, the Other or Both
The audience here is owners, partners, shareholders and finance leads of closely held companies who are deciding what each policy is for.
- Key person insurance is relevant to a business of any form that depends materially on one or more individuals, owners or not. That includes a partnership, LLC, S corporation, C corporation or sole proprietorship. Under Notice 2009-48 A-5, "employee" for section 101(j) purposes includes an officer, director and highly compensated employee.
- Buy-sell insurance is relevant to businesses with two or more owners who want a funded mechanism for transferring ownership at death or exit. A sole proprietorship with no co-owner has no one on the other side of the purchase.
- Both may appear in a closely held business with several owners and one or more critical non-owner employees.
- Neither may apply to a business with no individual whose loss would cause measurable harm, or to a single-owner business with no succession plan.
Professional practices, such as medical, legal, accounting and dental practices, may be subject to ownership and licensing rules that vary by state.
When Key Person Insurance May Fit
Businesses commonly consider key person coverage in situations like these:
- Revenue, client relationships or operations depend heavily on one or more identifiable people.
- A lender or investor asks for evidence that the business could withstand losing a principal. Lender requirements vary and are confirmed with the lender.
- The business wants funds to cover a search, recruiting and training period after an unexpected death.
- The insured is an employee, officer or owner whose loss would create a measurable financial gap.
Because the business is owner and beneficiary in each of these settings, the section 101(j) notice-and-consent conditions must be met before the contract is issued. Under Notice 2009-48 A-13, section 101(j) has no provision for correcting an inadvertent notice-and-consent failure, but the IRS will not challenge an exception based on one if the policyholder made a good-faith effort, the failure was inadvertent, and it was discovered and corrected by the due date of the tax return for the year the contract was issued. A failure to obtain written consent "cannot be corrected after the insured employee has died."
When Buy-Sell Insurance May Fit
Owners commonly weigh buy-sell funding in situations like these:
- Two or more owners want a binding, funded way to move a deceased owner's interest to the survivors or back to the entity.
- The owners want to avoid having a deceased owner's heirs or estate become co-owners.
- The agreement already has a fixed price or a formula that a death benefit can fund.
- The owners are choosing between entity purchase and cross-purchase. That choice affects who owns the policies and whether section 101(j) is in play, and it is a separate comparison.
Two issues usually travel with this arrangement. Valuation shapes how much coverage the agreement calls for. Reassigning policies between owners later can raise the section 101(a)(2) transfer-for-value rule.
When Neither May Fit
Some situations call for different tools, or for none of the business life insurance discussed here.
- A sole proprietorship with no co-owners has no buy-sell purchase to fund, although key person insurance may still apply if it depends on a non-owner employee.
- A business with no identifiable individual whose loss would cause measurable harm may have no key person exposure.
- Owners whose buy-sell agreement is already fully funded may have no gap to fill.
- When the main concern is estate liquidity for a closely held business interest, rather than operations or ownership transfer, other planning tools may be more relevant.
- A gradual transfer of ownership over time is a distinct succession strategy, compared on its own page on this site.
Decision Framework: Questions That Shape the Choice
The questions below help a reader frame the issue. They do not supply an answer:
- What business problem is the insurance meant to solve: lost operating value, or the purchase of an ownership interest?
- Is the insured an owner, a non-owner, or someone who is both an owner and critical to operations?
- Does the business have a buy-sell agreement, or is one being planned?
- Who will own each policy, pay its premiums and be its beneficiary?
- Have the section 101(j) notice-and-consent requirements been evaluated before the contract is issued?
- Could policies later be reassigned, and how would section 101(a)(2) treat that transfer?
- Is there a current valuation for buy-sell funding purposes?
The answers depend on the business's facts, its entity form and its existing agreements. Structure, ownership and tax treatment are confirmed with qualified tax, legal and insurance professionals.
Common Mistakes: Confusing Purpose, Ownership and Tax Requirements
Most errors come from treating one policy as if it were the other.
- Mixing purposes. Key person proceeds paid to the business create no obligation to buy an owner's interest. Without a buy-sell agreement, nothing sets the price or binds the parties.
- Missing the notice-and-consent timing. Under 26 U.S.C. § 101(j), the cap applies if either the exception or the notice and consent is missing. Neither one alone lifts it. Notice 2009-48 A-7 says actual knowledge cannot substitute for written notice and consent, even for a wholly owned corporation.
- Assuming premiums are deductible. Section 264(a)(1) denies the deduction when the taxpayer is directly or indirectly a beneficiary.
- Overlooking transfer for value. Moving policies between co-owners can bring section 101(a)(2) into play.
- Letting coverage go stale. If the business's value changes materially while coverage stays the same, the agreement's price and its funding can drift apart.
- One policy, two purposes. Section 101(j)(3) turns on who actually owns the contract and who is its beneficiary, not on what the business intended. A single policy with no clear written allocation of its proceeds leaves that question open.
Hypothetical Example: A Three-Owner Business Using Both Arrangements
The following example is hypothetical and is not a coverage recommendation.
Assumptions:
- An S corporation has three equal owners.
- One owner is also the lead salesperson, a key person role.
- The owners agree the business is worth $2,700,000.
- The buy-sell agreement is funded by entity-purchase insurance: the business owns one policy on each owner for the value of that owner's interest.
- The business also owns a key person policy on the salesperson-owner for $1,000,000.
Arithmetic:
- Value of each one-third interest: $2,700,000 ÷ 3 = $900,000.
- Buy-sell coverage: 3 policies × $900,000 = $2,700,000.
- Key person policy on the salesperson-owner: $1,000,000.
- Total coverage on the salesperson-owner: $1,000,000 + $900,000 = $1,900,000.
- Total coverage the business owns: $2,700,000 + $1,000,000 = $3,700,000.
The business owns all four policies and is the beneficiary of each, so section 264(a)(1) denies a premium deduction on all of them. If the salesperson-owner dies, $1,000,000 goes to the business for operations, and $900,000 goes to the business to redeem that owner's interest. Each policy may be an employer-owned contract under section 101(j). The full exclusion would depend on a section 101(j)(2) exception and written notice and consent given before issuance. The actual valuation, agreement terms and tax treatment depend on facts specific to the business.

Frequently Asked Questions
Does key person insurance pay for buying out a deceased owner?
Not by itself. The business owns the policy, pays the premiums and receives the death benefit, which it may use to offset lost revenue or rebuild operations. A key person policy does not transfer anyone's ownership interest; a buy-sell agreement is the document that sets a price and binds the parties.
What are the tax consequences of key person life insurance for the business?
Section 264(a)(1) denies a premium deduction where the business is directly or indirectly a beneficiary. Section 101(a)(1) generally excludes death benefits from gross income. For employer-owned contracts, section 101(j) caps that exclusion at premiums and other amounts paid unless both an exception applies and written notice and consent were given before issuance.
Can a business use one policy for both key person and buy-sell purposes?
One policy can be described both ways, but without a written agreement allocating the proceeds, the two purposes can conflict. Section 101(j) turns on actual ownership and beneficiary status, not intent. How proceeds divide between operations and a purchase price depends on the agreement's terms.
What is the transfer-for-value rule and how does it affect buy-sell insurance?
Section 101(a)(2) limits the exclusion for a policy transferred for valuable consideration to that consideration plus later premiums and other amounts. Exceptions include 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. Restructurings often raise it.
Does section 101(j) apply to buy-sell life insurance?
Section 101(j) can apply to an entity-purchase policy the business owns on an employee-owner, because the business is owner and beneficiary. Notice 2009-48 A-1 states that a contract owned by an entity's owner to finance buying another owner's interest is not an employer-owned contract, which describes the typical cross-purchase.
Can a sole proprietorship use buy-sell insurance?
A sole proprietorship has one owner and no co-owner to buy the interest, so the buy-sell structure does not fit it. It may still hold key person coverage on a critical employee. Notice 2009-48 A-3 notes that a sole proprietor's policy on his or her own life is not an employer-owned contract.
