Business buy-sell: where permanent coverage usually wins on continuity, but term has a role.

Section 1

The buy-sell problem.

When a co-owner of a closely held business dies, three problems crystallise simultaneously. The deceased owner's estate suddenly holds an illiquid business interest that the surviving owners may not want to share with the estate's heirs. The surviving owners typically need to acquire the deceased owner's share to maintain operational continuity and control. And the estate often needs liquidity to settle final expenses, taxes, and bequests to other heirs. A buy-sell agreement, properly structured and funded with life insurance, solves all three problems at once: the surviving owners buy the deceased owner's interest at a pre-agreed valuation using insurance proceeds, the estate receives cash rather than a business interest, and operational continuity is preserved.

The two principal structural alternatives are cross-purchase (each owner personally owns life insurance on the other owners) and entity-redemption (the business itself owns life insurance on each owner). The tax basis treatment, premium funding source, and exit-event mechanics differ materially between the two, and the right choice depends on the number of owners, the relative ownership percentages, the tax bracket of the owners versus the business, and the specific exit-event triggers the partners want to anticipate.

Section 2

Why permanent coverage usually wins for buy-sell.

A closely held business partnership often continues for decades. A two-partner professional practice founded by partners at age 35 may continue through both partners' retirement at 65 or beyond, a 30-year horizon. A multi-generational family business may continue for 50, 75, or 100 years across multiple ownership generations. The buy-sell mechanism needs to be funded for the entire duration of the partnership, not for an arbitrary 10- or 20-year window.

Term life insurance covers a defined period and then expires. A 20-year term buy-sell policy on a 35-year-old partner expires at age 55, leaving the buy-sell unfunded for the rest of the partnership. Renewing term coverage at age 55 is materially more expensive than the original policy. Worse, if either partner has developed health conditions during the original term, the partner may be uninsurable for renewal at any price, leaving the buy-sell uncovered for an indefinite future.

Whole life or guaranteed universal life provides permanent coverage that does not expire with the partnership. The premium is materially higher than equivalent term but the coverage continues for the partner's entire life. For partnerships with indefinite time horizons, permanent coverage is the structurally correct product, and the premium is typically paid by the business as an ordinary operating expense (subject to specific tax treatment under IRC §264 and §101(j)).

Section 3

Cross-purchase mechanics.

In a cross-purchase structure, each owner personally owns a life insurance policy on each other owner. For a two-partner business, each partner owns one policy on the other; for a three-partner business, each partner owns two policies, one on each other partner. The complexity grows quadratically with the number of partners; for partnerships with four or more owners, the number of required policies becomes administratively unwieldy and entity-redemption is typically preferred.

The principal tax advantage of cross-purchase is that on a partner's death, the surviving partners receive a stepped-up basis in the acquired ownership interest equal to the purchase price. When the surviving partners eventually sell the business or their interests, this stepped-up basis reduces the capital gains tax on disposition. The disadvantage is that policy ownership and premium funding lie with the individual partners, which can be cumbersome and which may not align with cash flow constraints at the partner level.

For closely held businesses where partners have substantially different tax brackets or substantially different net worth, cross-purchase can create equity issues that the partners may not anticipate at agreement formation. Modelling the post-death partner experience under cross-purchase requires careful coordination with tax counsel to ensure the structure delivers the intended outcomes.

Section 4

Entity-redemption mechanics.

In an entity-redemption structure, the business itself owns one life insurance policy per owner. On a partner's death, the business receives the insurance proceeds, uses them to redeem the deceased partner's ownership interest from the estate, and the surviving partners' ownership percentages adjust upward proportionally. The administrative simplicity (one policy per owner regardless of number of partners) makes entity-redemption the typical choice for partnerships with three or more owners.

The principal tax disadvantage of entity-redemption is that surviving partners do not receive a basis step-up in the redeemed interest. Their basis remains at its pre-death level, which means a larger eventual capital gain on ultimate disposition. For partnerships with strong reinvestment dynamics that may continue for multiple generations, the long-run capital gain disadvantage of entity-redemption can be material.

Recent legal developments have complicated entity-redemption planning at the federal estate tax level. The Supreme Court's 2024 decision in Connelly v. United States held that for federal estate tax purposes, the value of life insurance proceeds received by an entity is included in the entity's valuation, which can substantially increase the estate tax exposure of the deceased owner's estate. The decision affects entity-redemption planning for high-net-worth partnerships above the federal exemption and may push more such partnerships toward cross-purchase structures or alternative tax-efficient buy-sell arrangements.

Section 5

When term life works for buy-sell.

Term life insurance for buy-sell makes sense in specific situations. First, when the partnership has a defined finite horizon. A two-partner consulting practice with a planned wind-down at the senior partner's retirement in 12 years can fund the buy-sell with 15-year term, allowing modest margin past the planned exit. The premium is materially lower than equivalent whole life, and the planned partnership end aligns with the term expiration.

Second, when the business cannot afford whole life premium during early years. A capital-constrained startup with two co-founders may use 20-year term as bridge buy-sell funding with a planned conversion to whole life or GUL at year 5 or 10 once cash flow supports the higher premium. The conversion clause on the term policy allows the upgrade without medical re-underwriting; this is one of the cleanest use cases for the conversion option.

Third, when the partners specifically want to separate the buy-sell function from the long-horizon retirement planning function. A buy-sell funded with term covers only the partnership exposure; the partners build retirement savings through tax-advantaged accounts separately. The structure can be more capital-efficient than bundling buy-sell funding with retirement saving inside a whole life policy.

Section 6

Valuation methodology and annual review.

The buy-sell valuation methodology is the single most important non-insurance detail of the agreement. Common methods include a fixed-price formula reviewed annually by the partners, a multiple-of-trailing-earnings formula (typically 3 to 8 times EBITDA depending on industry), a third-party independent appraisal performed at the time of triggering event, or hybrid combinations.

The valuation should be reviewed annually and explicitly reflected in the partner agreement minutes. Partnerships where the buy-sell valuation has not been reviewed in 5+ years often have valuations that are dramatically out of date, leading to either insufficient insurance coverage at the time of trigger or post-trigger disputes between surviving partners and the deceased partner's estate over the correct valuation.

The life insurance face amount should match the valuation method. For a fixed-price valuation of $4 million per partner, the insurance per partner should be $4 million. If the valuation grows over time, the insurance should be increased correspondingly, which typically requires new underwriting on each partner. Many partnerships build a planned coverage increase schedule into the original buy-sell to avoid the post-hoc underwriting that can be problematic if any partner has developed health conditions.

Section 7

Caveats and sourcing.

Buy-sell life insurance treatment under IRC §264 (premium deductibility), IRC §101(j) (employer-owned life insurance notice and consent), and IRC §101(a) (death benefit exclusion). Estate inclusion under IRC §2042. The Supreme Court's Connelly decision (2024) clarifies entity valuation treatment for closely held businesses with entity-redemption life insurance. Cash value tax-deferral under IRC §7702. State filings for permanent products under NAIC model regulations.
