10.3 Business Disability (Key Person, Buy-Sell, BOE)

Key Takeaways

  • Key person DI is owned by the business to offset lost revenue; premiums are not deductible and benefits are tax-free.
  • Disability buy-sell funds the purchase of a disabled owner's interest using a long 12-24 month elimination period; benefits are tax-free.
  • BOE reimburses fixed operating expenses (rent, payroll, utilities) but not the owner's salary.
  • BOE premiums are tax-deductible and benefits are taxable, the reverse of the other business coverages.
  • BOE uses a short elimination and benefit period because it bridges a temporary gap, not a permanent exit.

10.3 Business Disability (Key Person, Buy-Sell, BOE)

Disability insurance is not only personal; businesses buy three distinct coverages to survive an owner's or key employee's disability. Exams test the purpose, premium deductibility, and benefit taxation of each separately, and the rules differ from personal DI, so treat this section as its own memorization block. The throughline to remember is that taxation mirrors deductibility: if a business gets to deduct the premium, the resulting benefit is taxable; if it cannot deduct the premium, the benefit comes back tax-free.

Key person disability protects the business against lost revenue and the cost of replacing a disabled key employee whose skills, contacts, or leadership drive profits. The business owns the policy, pays the premium, and is the beneficiary; the key employee is the insured.

Tax treatment: premiums are not deductible as a business expense, and consequently the benefits the business receives are tax-free. The cash supports recruiting and training a replacement and offsets the profit drop while the key person is out.

A buy-sell agreement is a legal contract obligating remaining owners (or the business) to buy out an owner who becomes totally disabled; disability buy-sell insurance funds that purchase. It uses a long elimination period (commonly 12-24 months) because partners want to be sure the disability is permanent before forcing a buyout, and it pays as a lump sum or installments equal to the buyout price.

Tax treatment: premiums are not deductible, and benefits are received income-tax-free. The funds buy the disabled owner's interest, giving the disabled owner liquidity and the remaining owners full control. Distinguish this from BOE below, which pays expenses, not a purchase price.

Business overhead expense (BOE) insurance reimburses a small business or professional practice for fixed operating expenses while the owner is disabled, so the doors stay open until the owner recovers or the practice is sold. Covered expenses include rent, utilities, employee salaries, lease payments, and property taxes. It does not reimburse the owner's own salary or draw, since that is the role of personal DI.

BOE carries a short elimination period (15-30 days) and a short benefit period (commonly 12-24 months) because it is meant to bridge a temporary gap, not fund a permanent exit. Critically, BOE premiums are tax-deductible as a business expense, and the benefits are taxable to the business; however, the taxable benefit is offset by the deductible expenses it reimburses, so there is usually no net tax.

BOE is a reimbursement contract, not a fixed-indemnity one: it pays the lesser of the actual covered expenses incurred or the policy's monthly maximum. Suppose a dentist carries a $12,000 monthly BOE limit but, while disabled, actual rent, staff salaries, and utilities total only $9,000 in a month. The policy reimburses $9,000, not the full limit.

Many BOE contracts also include a carryover provision: if covered expenses in some months fall below the monthly maximum, the unused portion can be carried forward to a later month when expenses spike, effectively extending the dollar value of the benefit period. This makes BOE responsive to the uneven expense pattern of running a small practice.

Disability buy-sell agreements come in two structural forms the exam contrasts with their life-insurance cousins. Under a cross-purchase arrangement, each owner buys a disability buy-sell policy on every other owner; when one becomes disabled, the others use the proceeds to buy out the disabled owner directly. Under an entity (stock-redemption) arrangement, the business itself owns one policy on each owner and uses the proceeds to redeem the disabled owner's shares.

Cross-purchase becomes cumbersome with many owners because the number of policies grows quickly, while the entity form keeps administration centralized. In both cases the long elimination period and the lump-sum or installment payout match the buyout price set in the agreement, and the proceeds are received income-tax-free.

A common exam trap is assuming business DI replaces personal coverage. It does not. Key person protects the company's revenue, buy-sell funds the owners' purchase obligation, and BOE keeps the practice's overhead paid, but none of the three replaces the disabled owner's own paycheck or household income.

The owner's mortgage, groceries, and family expenses are covered only by personal disability income insurance. A complete plan for a small-business owner therefore typically layers a personal DI policy beneath one or more business coverages, and the producer must be able to articulate which dollar each policy protects.

Think of the three business coverages as answering three different questions when an owner is disabled. BOE answers the immediate question, who keeps the lights on this month, so it has the shortest elimination period and triggers first. Key person answers the next question, who replaces the lost revenue and recruits a successor, paying over a moderate horizon. Disability buy-sell answers the final question, once it is clear the owner will not return, who buys their stake and at what price, so it deliberately waits the longest before paying.

Because the three coverages address sequential needs, a sophisticated business plan often carries all three at once, with each policy's elimination and benefit period tuned to the moment its particular need arises. The exam rewards candidates who can match the right coverage to the right business problem rather than treating them as interchangeable.
