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

Key Takeaways

  • Key person disability insurance reimburses the business for losses when a vital employee becomes disabled; the business owns the policy and is the beneficiary.
  • Disability buy-sell insurance funds the purchase of a disabled owner's share under a buy-sell agreement.
  • Business overhead expense (BOE) insurance reimburses fixed operating costs, not owner income, during the owner's disability.
  • BOE benefits are taxable to the business but the reimbursed expenses are deductible, netting roughly even.
  • Buy-sell DI uses a long elimination period because share buyouts are not made over short disabilities.

Disability does not only threaten an individual's paycheck; it can cripple a business. Three distinct products address business exposures, and the exam expects you to know who owns each policy, who is insured, who receives benefits, and how benefits are taxed.

Key Person Disability Insurance

Key person disability insurance protects the business against the economic loss caused when an essential employee, such as a top salesperson, founder, or specialized engineer, becomes disabled. The disability of a key person can mean lost revenue, the cost of finding and training a replacement, and lost customer confidence.

BeneficiaryThe business

Benefits taxable?No (received tax-free)

Exam trap: Key person premiums are NOT deductible, and the benefits the business collects are tax-free. The business cannot deduct a cost incurred to protect its own profits.

Disability Buy-Sell Insurance

A buy-sell agreement is a binding contract that obligates the remaining owners (or the business) to buy a departing owner's interest upon a triggering event. Death is funded with life insurance; total disability is funded with disability buy-sell insurance.

How It Funds the Buyout

When an owner becomes totally and permanently disabled, the policy provides cash, often as a lump sum or installments, that the buyers use to purchase the disabled owner's share at the agreed price.

ElementDisability buy-sell
PurposeFund purchase of a disabled owner's interest
Elimination periodLong, commonly 12 to 24 months
Benefit formLump sum or installments
Premium deductible?No
Benefits taxable?No

Why the long elimination period? Owners do not want to buy out a partner who may recover in a few months. The 12 to 24 month wait confirms the disability is genuinely permanent before triggering an irreversible ownership transfer.

Funding Structures

  • Cross-purchase: each owner buys a policy on every other owner.
  • Entity (stock-redemption): the business owns one policy on each owner.

With three or more owners, cross-purchase requires many policies (n x (n-1)), so the entity method is often simpler.

A crucial drafting point is that the buy-sell agreement and the funding policy must agree on the disability definition and the valuation price. If the agreement triggers a buyout at total and permanent disability but the policy uses a 24-month own-occupation standard, a dispute can arise over whether the trigger has been met. Producers should confirm the legal agreement and the insurance contract use compatible definitions and the same valuation method, whether a fixed price, a formula, or an appraisal.

Business Overhead Expense (BOE) Insurance

Business overhead expense (BOE) insurance reimburses the fixed operating costs a small business or professional practice incurs while the owner is disabled. It keeps the doors open so the business survives until the owner recovers or sells.

What BOE Covers and Excludes

Covered fixed expensesNOT covered
Rent or mortgage interestThe owner's salary or draw
Employee salariesOwner profit
Utilities and phoneInventory or merchandise
Equipment leasesNew equipment purchases
Property taxes, insuranceIncome lost by the owner

BOE has a short elimination period (often 30 days) because rent and payroll come due quickly, and a short benefit period (commonly 12 to 24 months) because the business must reorganize, not be funded indefinitely.

Exam trap: BOE does NOT replace the owner's income. That is the job of an individual DI policy. BOE only pays the business's deductible operating expenses.

Taxation of Business DI

Business overhead expenseYesYesRoughly even because reimbursed expenses are deductible

BOE Tax Example

A practice receives $20,000 in BOE benefits in a month and uses it to pay $20,000 of deductible rent and payroll. The $20,000 benefit is taxable income, but the $20,000 of expenses is deductible, so the net taxable effect is approximately zero.

BOE benefit received (taxable)+$20,000
Deductible expenses paid-$20,000
Net taxable income from BOE$0
