Buy-Sell Agreement Funding
Buy-Sell Life Insurance for an S Corporation
Published October 9, 2026 · Updated October 9, 2026
Short Answer: How Life Insurance Funds an S Corporation Buy-Sell
Life insurance can fund an S corporation buy-sell agreement by paying cash at a shareholder's death, which a buyer then uses to purchase that shareholder's stock. In a cross-purchase, the co-shareholders own policies on each other. In a redemption, the corporation owns the policies and buys back the shares. Each structure carries different tax and ownership consequences.
This page is written for shareholders of closely held S corporations and the finance leads around them. It explains federal rules only; state insurance and corporate law vary by state, and how any rule applies depends on the facts of a particular agreement and its contracts.
Why Buy-Sell Funding Matters for S Corporation Shareholders
A shareholder's death leaves stock in the hands of an estate or heirs who may have no role in the business and may want cash. The surviving owners, or the corporation, may want the shares but lack the liquidity to buy them. A buy-sell agreement is a contract that obligates a named buyer to purchase a departing owner's stock at a stated price or by a stated formula.
The S corporation form sharpens the problem. Under 26 U.S.C. § 1361(b)(1), the number and type of shareholders an S corporation may have are limited, so who ends up owning the stock matters. Life insurance is one way to fund the purchase obligation: it pays a lump-sum death benefit at the moment the obligation arises. The plan is the agreement; the insurance only funds it. The general mechanics appear on the site's page on buy-sell life insurance.
How S Corporations Are Typically Structured for Ownership
Section 1361(b)(1) of the Internal Revenue Code defines a "small business corporation" as a domestic corporation that is not ineligible and that does not "(A) have more than 100 shareholders, (B) have as a shareholder a person (other than an estate, a trust described in subsection (c)(2), or an organization described in subsection (c)(6)) who is not an individual, (C) have a nonresident alien as a shareholder, and (D) have more than 1 class of stock."
The one-class rule is where buy-sell drafting meets S corporation status. Treas. Reg. § 1.1361-1(l)(2)(iii)(A) provides that buy-sell agreements, transfer restrictions and redemption agreements are disregarded in testing for identical distribution and liquidation rights unless a principal purpose is to circumvent the one-class requirement and the agreement sets a price "significantly in excess of or below the fair market value of the stock." Paragraph (B) separately disregards "bona fide agreements to redeem or purchase stock at the time of death, divorce, disability, or termination of employment."
The Triggering Events an S Corporation Buy-Sell Addresses
Death is the event life insurance funds directly. Agreements commonly name other triggers as well, such as permanent disability, retirement or departure, termination of employment, divorce, bankruptcy, or an attempted transfer to someone the agreement does not permit. Disability buyout coverage is a separate product and is not developed here.
At a death, the estate holds the stock until someone buys it. In an S corporation, the identity of the next owner carries a particular risk: a transfer to a nonresident alien, or to a person who is not an individual and is not an estate, a trust described in section 1361(c)(2) or an organization described in section 1361(c)(6), conflicts with the statutory definition in section 1361(b)(1). Transfer restrictions in the agreement are one way owners try to keep stock with eligible holders.
The price clause sets how much the buyer pays and how much insurance the plan targets. Business valuation for buy-sell funding needs individual review of the agreement and facts by the parties' qualified tax, legal and insurance professionals. The site's page on business valuation for buy-sell explains how price clauses work.
How Life Insurance Funds an S Corp Buyout
Two structures dominate an s corporation buy sell agreement.
Cross-purchase. Each shareholder owns, pays the premiums on, and is the beneficiary of a policy on each co-shareholder's life. At a death, the survivors collect the proceeds and buy the deceased shareholder's stock from the estate.
Redemption (entity purchase). The S corporation owns the policies, pays the premiums and is the beneficiary. At a death, it collects the proceeds and redeems, or buys back, the shares from the estate.
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," except as limited by, among others, the transfer-for-value rule in section 101(a)(2) and the employer-owned contract rule in section 101(j). How the redemption itself is taxed to the estate and shareholders depends on facts this page does not state. The site's comparison of cross-purchase and entity purchase sets the two side by side.
Ownership Structure and the Transfer-for-Value Trap
Who owns each policy decides which limits on the exclusion can apply.
Transfer for value. Under section 101(a)(2), when a policy is transferred "for a valuable consideration," the exclusion "shall not exceed an amount equal to the sum of the actual value of such consideration and the premiums and other amounts subsequently paid by the transferee." Section 101(a)(2)(B) lifts that limit for 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." A transfer to the S corporation in which the insured holds stock fits that list. A co-shareholder does not. Moving a corporate-owned policy to a co-shareholder for value, for example when converting a redemption plan into a cross-purchase, can therefore leave part of the death benefit taxable. Section 101(a)(2)(A) contains a separate carryover-basis exception that turns on the facts of the transfer.
Employer-owned contracts. IRS Notice 2009-48, A-1, states that a contract owned by the owner of an entity "for purposes of financing the purchase of an equity interest of another owner" is not an employer-owned contract, which describes cross-purchase policies. Corporate-owned redemption policies can be. Section 101(j)(1) caps the exclusion at "the sum of the premiums and other amounts paid by the policyholder" unless a section 101(j)(2) exception applies and the section 101(j)(4) notice and consent requirements were met "before the issuance of the contract." One exception, 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. Notice 2009-48, A-5, states that "employee" includes an officer, director and highly compensated employee. A-7 states that no exception excuses "a wholly-owned corporation and its employee-owner" from written notice and consent.
Estate inclusion. Section 2042 includes proceeds receivable by the executor, and proceeds receivable by others where the decedent held "any of the incidents of ownership." Treas. Reg. § 20.2042-1(c)(2) lists, among others, the power to change the beneficiary, surrender or assign the policy, or borrow against it, and refers to separate rules on when incidents held by a corporation are attributed to a decedent "through his stock ownership". Paragraph (c)(6) of that regulation provides that where the decedent is the sole or controlling stockholder, a corporation's incidents of ownership will not be attributed to the decedent through stock ownership to the extent the proceeds are payable to the corporation, and will be attributed as to any part of the proceeds not payable to or for the benefit of the corporation.
Transfers of policies between owners, section 101(j) notice, consent and reporting, and section 2042 estate inclusion each need individual review of the contracts involved, by the insurers and a qualified tax professional.
Coverage and Funding Considerations
Face amounts are usually tied to the agreement's price for each insured shareholder's interest, which is why the valuation clause drives the coverage figure. The site's page on sizing buy-sell coverage explains that link.
Premium deductibility is a short question. Section 264(a)(1) provides that "No deduction shall be allowed for ... Premiums on any life insurance policy ... if the taxpayer is directly or indirectly a beneficiary under the policy." In a redemption plan the S corporation is the beneficiary; in a cross-purchase each shareholder is the beneficiary of the policies he or she owns.
A separate S corporation rule concerns group coverage. IRS Publication 15-B (2026) states that an employer "can't treat a 2% shareholder of an S corporation as an employee" for the group-term life insurance exclusion, so the cost of that coverage is included in the shareholder's wages for income tax and for social security and Medicare taxes. That rule concerns fringe benefits; it does not prevent using insurance to fund a buy-sell agreement.
Premiums, policy types and terms vary by insurer and are confirmed with the insurers involved. Cash value in a permanent policy is a contract feature, not an investment.

Who This Page Is For
The page addresses shareholders of S corporations with two or more owners who are weighing how a buy sell agreement s corp life insurance arrangement could fund a purchase at a death. It also fits owners comparing cross-purchase and redemption structures against their own ownership profile, and companies whose buy-sell agreement exists but whose funding has not been looked at since the ownership or the business value changed. Tax, legal and insurance advisers working on ownership transitions for S corporation clients are part of the audience.
It does not address a single-shareholder S corporation, where no co-owner exists to buy, nor publicly traded companies or C corporations.
When Life Insurance Funding May Fit
Insurance funding is commonly considered when several facts line up:
- The corporation has two or more shareholders and a written agreement, or a planned one, that obligates a purchase at a death.
- Neither the survivors nor the corporation holds enough liquid assets to pay the price without disrupting the business.
- The shareholders are insurable at a cost the owners judge proportionate to the interests involved.
- Ownership is stable enough that policies are unlikely to move between owners, which limits transfer-for-value exposure.
- The agreement's terms have been read against the one-class-of-stock rule and the eligible-shareholder limits in section 1361(b)(1).
Fit is a judgement about these facts, not a conclusion this page can reach for any company.
When Life Insurance Funding May Not Fit
Some situations strain the approach. A shareholder may be uninsurable, or coverage may cost too much relative to the interest it would fund. Frequent changes in ownership can force policies to be moved, and a sale of a policy to a co-shareholder falls outside the section 101(a)(2)(B) list.
A sole shareholder has no co-owner obligation to fund. An agreement whose price is set significantly above or below fair market value with a principal purpose of circumventing the one-class rule falls outside the disregard in Treas. Reg. § 1.1361-1(l)(2)(iii)(A). And where stock could pass to an ineligible holder before the agreement operates, insurance funds the purchase but does not by itself control the transfer that happens first.
Potential Advantages of a Funded Agreement
Timing is the central feature: the death benefit arrives when the purchase obligation arises, so buyers need not sell business assets or borrow to meet it. Section 101(a)(1) generally excludes death proceeds from the beneficiary's gross income, subject to the transfer-for-value limit and the section 101(j) cap where they apply.
Funding also supports the agreement's ownership goals. When stock moves promptly to co-shareholders or back to the corporation, the remaining holders are known parties rather than heirs whose eligibility under section 1361(b)(1) is uncertain. Treas. Reg. § 1.1361-1(l)(2)(iii)(B) disregards bona fide agreements to purchase stock at death, divorce, disability or termination of employment in the one-class analysis, which means a bona fide death-triggered agreement does not by itself create a second class. None of these features is a result any particular company can count on without review.
Important Considerations and Risks
Co-shareholder transfers. Section 101(a)(2)(B) names the insured, a partner of the insured, a partnership in which the insured is a partner, and a corporation in which the insured is a shareholder or officer. A fellow shareholder is absent, so converting a redemption plan into a cross-purchase by selling policies to the owners is the classic trap.
Controlling-shareholder estate inclusion. Under Treas. Reg. § 20.2042-1(c)(6), described above, whether a corporation's incidents of ownership are attributed to a sole or controlling stockholder depends on whether the proceeds are payable to the corporation. Separately, in Connelly v. United States, 602 U.S. 257 (2024), an estate tax valuation case, the Supreme Court held that the contractual obligation of the corporation before it to redeem a decedent's shares "did not diminish the value of those shares." The corporation in that case had bought the life insurance policies and received the proceeds. The Court decided only that question.
Employer-owned contracts. Notice 2009-48 answers many configurations but not every one. Section 6039I requires an applicable policyholder owning employer-owned contracts issued after the section's enactment to file a return for each year such contracts are owned, and to keep records. Notice 2009-48, A-13, states that a failure to obtain written consent "cannot be corrected after the insured employee has died."
Not covered here. S corporation basis and distribution rules are not addressed here and need review by a qualified tax professional. Insurer forms, underwriting and terms vary and are confirmed with the insurers involved.
Alternatives to Life Insurance Funding
Other methods can fund an S corporation buyout. The main ones:
- Sinking fund. The corporation or owners set cash aside over time. No insurance is involved, but the fund may be too small if a death comes early.
- Installment payments. The buyer pays the price over years from business earnings, which leaves the estate exposed to the buyer's credit and ties up future cash flow.
- Third-party financing. A lender advances the price, with interest and repayment terms set by the lender's own policy.
- Disability buyout coverage. A separate product for a disability trigger, not a death.
Each carries its own cost, risk and tax profile, and many agreements combine methods. The site's page on funding a buy-sell agreement compares them.
Planning Example (Hypothetical)
This example is hypothetical, uses round figures and describes no reader's business. Its assumptions:
- Two unrelated shareholders, A and B, each own 50 percent of an S corporation.
- The agreement prices the company at $2,000,000, and each interest at $1,000,000.
- Policies are newly issued, never transferred, and in force at A's death.
Cross-purchase. B owns a $1,000,000 policy on A, and A owns a $1,000,000 policy on B. At A's death, B collects $1,000,000, generally excluded under section 101(a)(1) subject to its limits. B pays A's estate $1,000,000 for A's shares. That leaves $1,000,000 − $1,000,000 = $0 of the proceeds unspent, and B now owns 50% + 50% = 100%.
Redemption. The corporation owns a $1,000,000 policy on each shareholder. At A's death, it collects $1,000,000, with the section 101(j) analysis depending on whether an exception applied and notice and consent were given before issue. It pays A's estate $1,000,000 to redeem A's shares.
In both versions, section 264(a)(1) bars a premium deduction to the policy owner who is the beneficiary. How the redemption is taxed and what basis each party ends up with depend on facts the example does not assume.

Frequently Asked Questions
What are the tax implications of a buy-sell agreement funded by life insurance in an S corporation?
The death benefit is generally excluded from gross income under section 101(a)(1), subject to the transfer-for-value limit and, for corporate-owned policies, the section 101(j) cap. Section 264(a)(1) allows no premium deduction when the payer is directly or indirectly a beneficiary. Tax treatment of the stock purchase or redemption, and S corporation basis effects, depend on facts and are confirmed with a qualified tax professional.
What is the transfer-for-value trap in an S corporation buy-sell agreement?
It is the income tax exposure that arises when a policy is moved to a co-shareholder for value. Section 101(a)(2) limits the exclusion to the consideration plus later premiums, and the section 101(a)(2)(B) exceptions name the insured, a partner, a partnership in which the insured is a partner, and a corporation in which the insured is a shareholder or officer, not a co-shareholder.
Can a buy-sell agreement create a second class of stock in an S corporation?
Generally not, if it is bona fide. Treas. Reg. § 1.1361-1(l)(2)(iii) disregards bona fide agreements to purchase or redeem stock at death, divorce, disability or termination of employment. Other buy-sell agreements are disregarded unless a principal purpose is circumventing the one-class rule and the price is significantly above or below fair market value when the agreement is made.
Does the employer-owned life insurance rule under § 101(j) apply to an S corporation's buy-sell policies?
It can apply to policies the corporation owns on shareholder-employees that meet the section 101(j)(3) definition. Notice 2009-48, A-1, states that 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 life insurance contract. For corporate-owned contracts, the exclusion is capped at premiums paid unless a section 101(j)(2) exception applies and written notice and consent were given before issue. Whether a particular arrangement qualifies depends on its facts.
