Most small business buy-sell agreements are written with good intentions and funded inadequately, or not at all. The agreement specifies what happens when an owner dies or exits. The funding is what makes the agreement executable. Without it, the surviving owner owes the deceased's estate the buyout price with no mechanism to pay it, no timeline the estate is required to accept, and no protection against the estate choosing to bring a new partner into the business instead.
Life insurance solves the liquidity problem precisely because the death benefit arrives as a lump sum at the moment it is needed, not after years of cash accumulation. For brokers working with business owner clients, the buy-sell conversation and the key person conversation are two distinct structures with different owners, beneficiaries, tax rules, and documentation requirements. Understanding the mechanics before the conversation starts is the difference between adding value and adding confusion.
Key Takeaways
- A buy-sell agreement is a legally binding contract between business co-owners that specifies how an ownership interest transfers if an owner dies, becomes disabled, or exits the business. Life insurance is the most common funding mechanism because the death benefit arrives as a lump sum precisely when the liquidity is needed.
- Cross-purchase agreements require each owner to hold a policy on every other owner. For a 2-owner business that works cleanly: 2 policies, each equal to the other owner's buyout value. For 3 owners the math becomes 6 policies, and for 4 owners it becomes 12. An entity-purchase (stock redemption) agreement routes ownership through the business entity, requiring only one policy per owner regardless of how many co-owners exist.
- Key person coverage insures an individual whose loss of productivity, expertise, or relationships would cause measurable financial harm to the business. The business owns the policy, pays the premiums, and receives the tax-free death benefit. Premiums paid for key person coverage are not deductible as a business expense under IRC Section 264.
- Section 101(j) of the Internal Revenue Code requires that the insured employee receive written notice and give written consent before the policy is issued, and that the employer file IRS Form 8925 annually. Employer-owned life insurance that fails the 101(j) requirements has proceeds above basis taxable as ordinary income, eliminating the tax-free benefit that makes the structure work.
- Buy-sell valuation is a recurring broker task, not a one-time setup. Business values change. A buy-sell agreement funded with a $500,000 life insurance policy written in 2018 for a business now worth $1.4 million leaves a $900,000 funding gap. Reviewing valuation and coverage every 3 to 5 years is part of the service model.
Cross-purchase vs entity-purchase: which structure fits the business
The first structural decision is who holds the policies and who receives the death benefit. There are two common approaches.
| Factor | Cross-purchase | Entity-purchase |
|---|---|---|
| Who owns the policies | Each owner holds policies on every other owner. | The business entity holds one policy per owner. |
| Who receives the death benefit | The surviving owner(s) receive the proceeds to fund the buyout directly. | The business entity receives the proceeds and uses them to redeem the deceased owner's interest. |
| Number of policies for 3 owners | 6 policies (each of 3 owners insures the other 2). | 3 policies (one on each owner, held by the business). |
| Capital gains basis for surviving owners | Better outcome: surviving owners receive a step-up in the deceased's share, improving basis for a future sale. | Surviving owners do not get a step-up; their basis in their original shares is unchanged. |
| AMT exposure for C-corporations | Not applicable at the individual owner level for life insurance proceeds. | C-corporations must include life insurance proceeds in the alternative minimum tax calculation. Not an issue for S-corps, LLCs, or partnerships. |
Illustrative comparison. Tax and legal implications vary by business entity type and state. Refer clients to a CPA and business attorney before finalizing agreement structure.
For a 2-owner business, either structure works. The cross-purchase approach gives surviving owners a better capital gains basis on a future sale of the business because their basis is stepped up by the amount paid to acquire the deceased owner's interest. Entity-purchase is simpler administratively for businesses with 3 or more owners because the entity holds one policy per owner rather than requiring each owner to maintain policies on every other owner.
The policy count matters in practice. A 4-owner business with a cross-purchase agreement requires 12 separate life insurance policies, each sized to fund the applicable owner's buyout value. An entity-purchase agreement for the same business requires 4 policies. Most small businesses with 3 or more owners use an entity-purchase structure for this reason.
Key person coverage: who qualifies and how much is enough
Key person life insurance is not for every employee. It is for individuals whose absence from the business would cause a measurable revenue or operational loss that takes time and money to replace. Common qualifying criteria include: the individual generates a disproportionate share of revenue, they hold technical expertise or certifications that cannot be hired off the street quickly, they are the primary relationship holder with major clients or suppliers, or their loss would trigger a covenant in a loan or credit agreement.
Sizing the coverage is a business conversation, not a formula. Some approaches use a multiple of the individual's compensation (typically 5 to 10 times annual salary), which is simple but ignores the revenue impact. Others use a replacement cost approach: how much would it cost to recruit, hire, and train a successor while maintaining business operations during the gap? A business that generates $600,000 per year in revenue tied primarily to one salesperson with a 2-year replacement timeline would want coverage in the $900,000 to $1,200,000 range, not simply 5 times the salesperson's $120,000 salary.
The tax treatment is unambiguous: premiums paid by the business for key person coverage are not deductible under IRC Section 264. The death benefit is received income-tax-free by the business under Section 101(a), provided that the notice-and-consent requirements of Section 101(j) are met. Inshura and some other business insurance quoting platforms flag 101(j) consent requirements in their application workflows, but the broker is responsible for ensuring the documentation is completed correctly regardless of what any platform surfaces.
Section 101(j): the consent requirement that makes or breaks the tax treatment
Section 101(j) applies to any policy where the employer is both the owner and the beneficiary and the insured is or was an employee at the time of issue. This covers the vast majority of business life insurance arrangements.
The requirements are not complex, but they must happen before the policy is issued. The employer must provide the insured employee with written notice that specifies: the employer intends to insure the employee's life, the maximum face amount for which the employee could be insured, and the fact that the employer will be the policy's beneficiary. The employee must sign a written consent acknowledging this. These steps must be completed before the application is submitted.
After the policy is in force, the employer must file IRS Form 8925 with its annual tax return each year, disclosing the number of current and former employees insured under employer-owned policies and the aggregate face amount outstanding. The form is straightforward, but it is frequently overlooked by businesses that completed the 101(j) consent correctly and then forgot the annual reporting obligation.
A policy that fails the 101(j) requirements because consent was not obtained before issue does not disqualify the death benefit entirely. It limits the income-tax exclusion to the employer's basis in the contract. If the employer paid $100,000 in premiums over 15 years and the death benefit is $1.2 million, the employer can exclude $100,000 and must include $1.1 million as ordinary income. That is a tax consequence most business clients do not anticipate and most brokers do not mention until it is too late to fix.
Valuation review: the gap that opens quietly over time
A buy-sell agreement and its funding are two separate documents maintained on two different timelines. The agreement may specify that valuation is updated every three years. The life insurance policies are reviewed whenever a premium notice arrives, which is to say they are not reviewed on a business-value schedule at all.
The result is common: a 2-owner professional practice wrote a cross-purchase agreement in 2019 when the practice was valued at $800,000. Each owner took out a $400,000 policy on the other. By 2026 the practice has grown to $1.6 million. The existing coverage funds half the buyout. The surviving owner would need to find $800,000 from other sources to complete the transaction without the estate going to probate or accepting installment payments.

For clients whose original buy-sell used term coverage that is approaching its conversion window, see life insurance term conversion privilege: the window, the cost, and why most clients let it lapse unused.
The practical broker workflow is to add a buy-sell valuation review to the same calendar as employer health insurance renewals. The employer-group client relationship already provides an annual touchpoint. Adding a single question at each renewal, asking whether the business valuation has been updated since the last time coverage was reviewed, surfaces the gap before it becomes a crisis rather than after.
FAQ
Questions brokers ask about structuring life insurance for business owner clients.
What type of life insurance is most commonly used to fund a buy-sell agreement?
Term life is the most straightforward funding vehicle: it provides a large death benefit for the lowest initial premium, which matters when business owners are young and the buyout value is high relative to the available budget. The trade-off is that term coverage expires. If the buy-sell agreement is expected to remain in force past the term period, the business either buys new coverage at significantly higher rates or switches to permanent insurance. Some business owners fund buy-sell agreements with permanent life insurance from the start, specifically a guaranteed universal life policy, because the level premium locks in the cost for the duration of the agreement regardless of age or health changes. For clients where cash value accumulation is a secondary goal, whole life has been used, but the premium cost is substantially higher than term or GUL for the same death benefit.
Can a buy-sell agreement be funded with disability insurance rather than life insurance?
Yes, and the disability trigger is often the more likely event. A business owner in their 40s is statistically more likely to experience a long-term disability than death during the active business ownership period. Disability buy-sell insurance (also called business overhead expense or disability buyout insurance) pays a lump sum or monthly benefit that funds the purchase of the disabled owner's interest. The elimination period on disability buyout policies is typically 12 to 24 months, which is longer than individual disability income policies, and the benefit period is usually limited to 24 or 36 months. Life insurance and disability buyout insurance are often structured in tandem to cover both contingencies in the same buy-sell agreement. Separate riders on life policies can also address disability-triggered buyouts, but the terms vary significantly by carrier.
What is Section 101(j) and why does it matter for key person coverage?
Section 101(j) of the Internal Revenue Code governs employer-owned life insurance (EOLI), defined as any policy where the employer is both the policy owner and the beneficiary and the insured is an employee at the time the policy is issued. For the death benefit to remain income-tax-free under Section 101(a), the employer must: (1) notify the employee in writing before the policy is issued that the employer intends to insure the employee's life, (2) disclose the maximum face amount at issue and the fact that the employer will be the beneficiary, (3) obtain the employee's written consent to being insured, and (4) file IRS Form 8925 annually disclosing the number of employees covered and the total face amount of EOLI policies in force. Policies that fail the notice-and-consent requirement are not disqualified entirely, but the death benefit above the employer's basis (premiums paid) is taxable as ordinary income. For a $1 million key person policy where the employer paid $80,000 in premiums, a failed 101(j) election means $920,000 taxable at ordinary income rates. The fix is to get the consent before the policy issues, not afterward.
How should a broker approach the business valuation for a buy-sell agreement?
Brokers are not business appraisers, and taking on the role of establishing valuation creates E&O exposure. The right approach is to ask the business owners whether they have a buy-sell agreement, whether it specifies a valuation method, and when valuation was last updated. Common valuation methods are book value, capitalized earnings, or formula-based approaches, and the buy-sell agreement should specify which method applies and how often it is updated. A broker's role is to ensure the life insurance face amount is sufficient to fund the valuation figure at the time of the triggering event. If the agreement says the business is worth $700,000 and the existing policy has a $400,000 death benefit, the gap is the problem to solve. Referring the client to a CPA or business appraiser for the valuation number, and then sizing the coverage accordingly, keeps the broker's role clearly in the insurance lane.
Are there situations where life insurance is not the right funding vehicle for a buy-sell?
Yes. If the business has substantial cash reserves or credit access, a self-funded buyout may be more cost-effective than premium payments, particularly for older owners where term is expensive and permanent coverage carries high costs. Installment payment agreements, where the surviving owners pay the estate over time from business cash flow, are used when life insurance is not affordable or when the owners are uninsurable. Sinking funds (accumulated business reserves earmarked for a buyout) are another approach, though they have no death benefit mechanics and do not provide immediate liquidity at death the way a policy does. The insurance-funded structure remains the most common for businesses in growth phases because the benefit is available from the first day the policy is in force, not after years of accumulation.
