Buy-Sell Agreements for Business Partners: Using Life Insurance the Right Way

What a Buy-Sell Agreement Is and Why Every Business Partnership Needs One

A buy-sell agreement defines the price at which a departing owner's interest will be purchased and identifies who has the right or obligation to buy. There are two primary structures: a cross-purchase agreement (each owner individually buys out the departing owner's share) and an entity-purchase or redemption agreement (the business entity itself buys the departing owner's share). Without a buy-sell agreement, a business partnership can fracture catastrophically when one owner dies or becomes disabled. The deceased's family inherits the business interest. The surviving owners are now in business with grieving family members who may have no business expertise, different financial needs, and legitimate but potentially conflicting legal rights. The business may need to be liquidated to allow the family to access value, often at a discount and at the worst possible time. With a funded buy-sell agreement, the triggering event - death, disability, or retirement - activates a predetermined sale process. The surviving owners or the entity purchases the departing owner's interest at an agreed-upon price, using funds that were set aside specifically for this purpose. The deceased's family receives cash. The business continues under the remaining owners without interruption. The agreement covers not only death but also voluntary departures, divorces that might transfer ownership to an ex-spouse, disability that prevents an owner from contributing, and retirement exits. Each triggering event and its price formula should be defined explicitly in the agreement.

Why Term Insurance Falls Short as the Funding Vehicle

Most buy-sell agreements are funded with term life insurance because term is inexpensive at younger ages. A 40-year-old partner can buy $1 million in term coverage for $50-$80 per month. It is a simple, low-cost solution. The problem emerges 20 years later. A 20-year term policy purchased at 40 expires at 60. Partners in their 60s are statistically far more likely to die or become disabled than partners in their 40s. The coverage evaporates precisely when the risk peaks. Renewing term at 60 is far more expensive - and for partners with health conditions that developed in their 50s, coverage may be unavailable at any price. There is also no accumulation. Twenty years of term premium payments build zero cash value. The funding obligation is met only if the covered event occurs during the term period. If a partner wants to retire at 62 and exercise the buy-sell - a common voluntary departure scenario - term insurance provides no mechanism. The agreement needs to be funded with cash, from somewhere, and there is none in a pure term-insurance-funded structure. A third gap: term insurance typically does not cover disability buyout. A partner who becomes disabled and can no longer contribute may trigger the buy-sell agreement's disability provision. Funding that buyout requires a separate disability buyout insurance policy, which many agreements lack entirely.

Permanent Life Insurance as a Permanent Funding Solution

Permanent life insurance - including whole life and IUL - solves the durability problem that term insurance creates. The coverage does not expire at 65 or 70. A partner who dies at 72 triggers the death benefit provision of the buy-sell agreement, and the life insurance policy that has been in force for 30 years provides the funds as intended. IUL specifically provides an additional benefit that term insurance cannot: cash value accumulation. Premiums paid into an IUL policy above the cost of insurance grow as cash value within the policy. That cash value can be used by the living partner for multiple purposes. If a partner wants to retire and trigger the buy-sell's voluntary departure provision, the surviving partner can take policy loans from the IUL's accumulated cash value to fund part of the buyout. The cash value grows tax-deferred during the accumulation years and is accessible via policy loans that generate no taxable income. For the living partner using IUL for their own retirement planning, the cash value that has been building during the years of buy-sell coverage also serves as personal retirement capital. In a cross-purchase buy-sell funded with IUL, each partner owns a policy on the other's life. Partner A owns an IUL on Partner B, and vice versa. If Partner B dies, Partner A receives the death benefit income-tax-free and uses it to buy Partner B's share from the estate. Partner A's cost basis in the business interest steps up, which reduces future capital gains tax when Partner A eventually sells.

• Review existing buy-sell agreements to confirm the funding mechanism has not lapsed or expired
• Determine whether the current policy death benefit matches the current business valuation
• Update the buy-sell agreement whenever the business valuation changes significantly
• Decide between cross-purchase and entity-purchase structures with your attorney
• Evaluate whether permanent insurance provides better long-term value than renewals of expiring term
• Address disability buyout funding - most term policies do not cover this trigger

IUL in the Buy-Sell Context: The Dual-Purpose Advantage

The strongest case for IUL over term in a buy-sell context is the dual-purpose function. Term insurance serves one purpose: it pays at death. When it does not pay (because the term expires before death or because the triggering event is retirement rather than death), it was a pure cost with no residual value. An IUL serves two purposes simultaneously. First, it provides the death benefit that funds the buy-sell at death. Second, the cash value it accumulates provides the living partner with retirement income, buyout liquidity for retirement exits, or a fund for other business needs. Neither function is sacrificed for the other - the policy provides both as long as it remains in force. For a business partnership where both partners are 45, buying 20-year IUL policies on each other means the cash value will have grown for 20 years by the time they are 65 - prime retirement and exit territory. If the buy-sell is never triggered by death, the cash value is still available. If one partner dies at 60, the survivor receives the death benefit and continues using their own policy's cash value for retirement income. The cost of IUL is higher than term in the early years. But comparing term insurance cost to IUL cost over 30 years, accounting for the cash value that accumulates in the IUL, often shows IUL provides comparable or superior total value when both the protection function and the accumulation function are counted.

Coordinating the Buy-Sell With Business and Personal Retirement Planning

A buy-sell funded with IUL intersects with personal retirement planning in a way that requires coordination between the business attorney, the financial advisor, and the insurance professional. From a business planning perspective, the buy-sell should define the valuation method - whether fixed price, formula-based (such as a multiple of EBITDA), or professionally appraised at the triggering event. The insurance coverage should match the current valuation, which means reviewing and potentially increasing coverage as the business grows. From a personal planning perspective, the cash value in the partner's IUL policy is an asset that should appear in their personal retirement plan. If Partner A has $400,000 in cash value in an IUL at age 60, those are retirement dollars available via policy loans - even though the original purpose was buy-sell funding. The retirement plan and the buy-sell plan share the same asset base. One additional consideration: if the business pays the IUL premiums as part of an executive compensation arrangement, the tax treatment differs from personally owned policies. Business-owned life insurance (BOLI) has specific IRAS-regulated rules around deductibility and taxation. Partners should understand whether premiums are business-deductible (generally they are not under IRC 264 for BOLI) and how that affects the economics compared to personally paying premiums. The bottom line for business owners: a funded buy-sell agreement is not optional insurance on your partnership - it is essential business infrastructure. And a permanent, cash-value-building policy provides that infrastructure without expiring at the worst possible time.
