10.3 Business Disability (Key Person, Buy-Sell, BOE)
Key Takeaways
- Key person DI protects the business against losing an essential employee; the business owns it, pays it, and is the beneficiary, with non-deductible premiums and tax-free benefits.
- Disability buy-sell funds the buyout of a totally and permanently disabled owner and uses a long (12–24 month) elimination period to confirm permanence.
- Business overhead expense (BOE) reimburses fixed expenses like rent, utilities, and non-owner salaries — never the owner's own salary or inventory.
- BOE is the tax exception: premiums ARE deductible, so benefits are taxable (the effect typically washes against deductible expenses).
- BOE uses short elimination and benefit periods (30 days / 1–2 years) and reimburses actual expenses up to a monthly maximum.
Three Business Uses of Disability Insurance
DI is not only personal. The national portion tests three distinct business disability products. The trick is matching the right product to the business problem — they are NOT interchangeable, and each has a different owner, payer, beneficiary, and tax outcome.
1. Key Person (Key Employee) Disability
Protects the business against the economic loss caused when an essential employee becomes disabled. The company is the applicant, owner, premium payer, and beneficiary; the key employee is the insured.
- Funds the cost of finding, hiring, and training a replacement and offsets lost revenue while a critical person (top salesperson, lead engineer, founder) is out.
- The business must demonstrate an insurable interest in the key employee.
- Tax rule: premiums are not tax-deductible to the business; consequently benefits are received income-tax-free by the business. This mirrors key-person life insurance.
2. Disability Buy-Sell
Funds a buy-sell agreement so that, if an owner becomes totally and permanently disabled, the remaining owners (or the business) can buy out the disabled owner's interest.
- Prevents a disabled, non-contributing owner from continuing to draw profits and ensures the disabled owner (or family) receives fair value for the business stake.
- Uses a long elimination period — commonly 12 to 24 months — because partners want certainty that the disability is permanent before forcing a buyout.
- Benefits may be paid as a lump sum or in installments to fund the purchase price.
- Tax rule: premiums are not deductible; benefits used to purchase the interest are received tax-free.
3. Business Overhead Expense (BOE)
Reimburses a disabled business owner for the fixed monthly operating expenses of the business so the doors stay open during the owner's recovery. Most relevant to small professional practices (dentists, attorneys, accountants) where the owner is the revenue.
- Covered expenses: rent/mortgage interest, utilities, employee salaries (non-owner), leased equipment, insurance premiums, accounting and legal fees, property taxes.
- NOT covered: the owner's own salary or draw, and the cost of inventory or goods. BOE pays the overhead, not the owner's income (that is what personal DI is for).
- Benefit periods are short — commonly 1 to 2 years — with short elimination periods (30 days) because overhead bills arrive monthly.
- BOE reimburses actual expenses up to a monthly maximum; if actual expenses are below the maximum, only actual expenses are paid (and some policies let unused amounts carry forward).
- Tax rule (the key contrast): BOE premiums ARE tax-deductible as a business expense, so benefits are taxable income to the business. Because the benefits offset deductible business expenses, the net tax effect typically washes out.
Tax Treatment Drives Each Business DI Product
The exam's favorite business-disability angle is who deducts the premium and who is taxed on the benefit. For key person DI, the business pays and owns the policy; premiums are not deductible, but the benefit is tax-free to the business. For a disability buy-sell, the owners or entity pay non-deductible premiums and the benefit funds the purchase of a disabled owner's interest tax-free. For Business Overhead Expense (BOE), premiums are deductible as a business expense, and the benefit is taxable -- but it reimburses deductible overhead, so it nets out.
| Product | Premium deductible? | Benefit taxable? | Purpose |
|---|---|---|---|
| Key person DI | No | No | Replace lost productivity |
| Disability buy-sell | No | No | Fund purchase of owner's share |
| BOE | Yes | Yes | Pay rent, salaries, utilities |
Business Overhead Expense Mechanics
BOE reimburses fixed business overhead -- rent, utilities, employee salaries, lease payments -- while the owner is disabled, but it does not replace the owner's own salary. It carries a short benefit period (often 12 to 24 months) because its job is to keep the doors open until the owner recovers or the practice is sold.
Worked BOE Reimbursement
A disabled dentist's monthly overhead is $18,000 (rent, staff, utilities), but his BOE policy caps reimbursement at $15,000 per month. BOE pays the lesser of actual covered overhead or the cap, so it reimburses $15,000, and the dentist covers the $3,000 shortfall. Because BOE is reimbursement-based, it never pays more than actual overhead incurred.
Disability Buy-Sell Funding
A buy-sell agreement funded by disability insurance specifies a triggering elimination period (often long, such as 12 months) before the buyout obligation matures, ensuring the disability is permanent before ownership changes hands.
Additional Exam Traps
- BOE premiums are deductible (benefit taxable); key person and buy-sell premiums are not deductible (benefit tax-free).
- BOE reimburses overhead, never the owner's salary.
- BOE pays the lesser of actual overhead or the policy cap.
A solo dentist becomes disabled. Which business disability product reimburses the practice for rent, staff salaries, and utilities — but NOT the dentist's own salary?
Side-by-Side Comparison
This table is the highest-yield study artifact for business DI. Watch the tax column closely — BOE is the odd one out.
| Feature | Key Person | Disability Buy-Sell | BOE |
|---|---|---|---|
| Problem solved | Loss of essential employee | Buy out disabled owner | Keep business overhead paid |
| Owner/payer | Business | Business or owners | Business |
| Beneficiary | Business | Remaining owners/business | Business (expense reimbursement) |
| Elimination period | Varies | Long (12–24 mo) | Short (30 days) |
| Benefit period | Short-medium | Lump sum or installments | Short (1–2 yrs) |
| Premium deductible? | No | No | Yes |
| Benefits taxable? | No | No | Yes |
| Covers owner's salary? | n/a | n/a | No |
Common Traps
- Confusing BOE with personal DI — BOE never pays the owner's salary.
- Assuming all business DI benefits are tax-free — BOE benefits are taxable because its premiums are deductible.
- Putting a short elimination period on a buy-sell — partners need a long EP to confirm permanence before triggering a buyout.
How the Products Work Together
A well-protected small business often layers all three products because each solves a different problem for a different party. Consider a three-owner engineering firm and walk through who suffers the loss in each case.
Key person DI on the lead structural engineer funds a search and replacement if she is disabled, cushioning the company's lost revenue. A disability buy-sell lets the other two owners buy out any owner who becomes permanently disabled, so a non-working partner does not keep drawing profits and the disabled partner still receives fair value for the equity stake. BOE keeps rent, software leases, and non-owner staff salaries paid while a working owner recovers from a shorter disability so the practice does not shut its doors.
Remember that personal DI still belongs on top of all three: none of the business products replaces an owner's personal paycheck. BOE pays the overhead, buy-sell transfers the equity, key person cushions the company — but only an individual or group DI policy replaces the disabled owner's own spendable income. A complete plan therefore stacks personal DI under the business coverages rather than treating any one of them as a substitute.
