14.3 Business Disability (Key Person, Buy-Sell, Business Overhead)

Key Takeaways

  • Key person disability protects the business against lost productivity when a vital employee becomes disabled; the business owns the policy, pays premiums, and receives the benefit.
  • A disability buy-sell policy funds the purchase of a disabled owner's interest, usually after a long elimination period of 12 to 24 months.
  • Business Overhead Expense (BOE) insurance reimburses fixed business expenses (rent, utilities, employee salaries) during the owner's disability, not the owner's personal income.
  • BOE benefits are limited to actual covered expenses incurred, so it functions on a reimbursement basis rather than a fixed monthly payout.
  • Key person disability premiums are not deductible, and the benefit is received tax-free by the business.

When a disability strikes a business owner or essential employee, the financial damage extends well beyond a single paycheck. Three specialized business disability products address separate exposures. Each has a different owner, payee, elimination period, and tax result, and the exam tests the producer's ability to match the right product to the fact pattern.

Key Person Disability Insurance

Key person (key employee) disability protects the business when a uniquely valuable person, a top salesperson, founder, or lead engineer, becomes disabled. The benefit cushions lost revenue and funds the cost of finding and training a replacement.

ElementTreatment

Premium payerThe business
Benefit recipientThe business
Premium deductible?No
Benefit taxable?No (received tax-free)

Key Point: Because the business cannot deduct the premium, the benefit comes back to the business income-tax-free. This pairing, non-deductible premium, tax-free benefit, mirrors key person life insurance.

Disability Buy-Sell Insurance

A buy-sell agreement is a contract among owners that requires the business or the remaining owners to purchase a departing owner's share. A disability buy-sell policy provides the cash to complete that purchase when an owner becomes totally disabled, so the disabled owner is bought out and the remaining owners keep control.

  • Long elimination period: typically 12 to 24 months, because owners want certainty the disability is permanent before triggering a buyout.
  • Funding methods: a lump-sum payment, an installment stream, or a down payment plus installments.
  • Tax treatment: premiums are not deductible; the benefit used to fund the purchase is received income-tax-free.

Trap: Do not confuse the long buy-sell elimination period with the short elimination period on personal income protection. A buyout should not fire after a few months of recovery-likely disability.

Business Overhead Expense (BOE) Insurance

Business Overhead Expense (BOE) insurance keeps a small business or professional practice operating while the owner is disabled. It reimburses fixed business expenses, not the owner's salary. Covered items include rent or mortgage interest, utilities, property taxes, equipment leases, and the salaries of non-owner employees.

BOE is a reimbursement contract: it pays the lesser of the actual covered expenses incurred or the policy's monthly maximum. Unused monthly amounts can often carry forward to later months within the benefit period.

FeatureBOE detail
What is coveredFixed business overhead (rent, utilities, staff salaries)
What is NOT coveredOwner's own salary or income, the cost of goods inventory
Elimination periodShort, often 30-90 days
Benefit periodShort, often 1-2 years
Premium deductible?Yes, as a business expense
Benefit taxable?Yes, but offset by the deductible expenses it reimburses

Worked example: A dentist's BOE policy has a $15,000 monthly maximum. During a covered month the practice incurs $11,500 of eligible overhead. BOE pays $11,500 (the lesser of actual expenses and the cap), not the full $15,000, because it reimburses real costs.

Exam Tip: Read the question for the purpose. If the goal is paying rent and staff while the owner recovers, choose BOE. If the goal is buying out a permanently disabled partner, choose disability buy-sell. If the goal is offsetting lost productivity, choose key person.

Tax Treatment of Business Disability Coverage

The tax result depends on who pays the premium and who receives the benefit - a recurring exam theme.

ProductPremium Deductible?Benefit Taxable?
Key person DINo (business is owner/payee)No (received tax-free)
Disability buy-sellNoNo (funds an ownership purchase)
Business overhead expense (BOE)Yes (ordinary business expense)Yes (reimburses deductible expenses)

The logic: when premiums are not deducted (key person, buy-sell), benefits arrive tax-free. When premiums are deducted (BOE), benefits are taxable - but they reimburse expenses the business will deduct anyway, so the net effect washes out. This deductible-premium / taxable-benefit symmetry is the single most tested point in business disability.

Matching Elimination and Benefit Periods to the Need

Each business product is structured around the timing of its specific exposure.

  • Key person DI uses a moderate elimination period and a benefit period long enough to recruit and train a replacement - often 12 to 24 months. The benefit funds lost revenue and search costs, not the disabled employee's salary.
  • Disability buy-sell uses a long elimination period (commonly 12 to 24 months) because owners do not want to trigger a forced buyout for a short-term disability. The waiting period confirms the disability is permanent before ownership changes hands. The benefit is then paid as a lump sum (or installments) to fund the purchase of the disabled owner's interest.
  • Business overhead expense (BOE) uses a short elimination period (typically 30 to 90 days) and a short benefit period (often 12 to 24 months) because rent, utilities, and staff salaries come due immediately and a small practice cannot wait. BOE reimburses actual covered expenses up to the policy limit, not a fixed sum, and explicitly excludes the owner's own salary.

Worked scenario: A disabled dental practice owner needs rent, utilities, and a hygienist's salary covered immediately while she recovers, but not her own income. The product is BOE - short elimination period, expense reimbursement, owner's salary excluded.
