Overview: Disability insurance has important applications beyond replacing an individual's personal income — it protects businesses from the financial consequences of losing key contributors.

Business Overhead Expense (BOE) Insurance

When a business owner or professional becomes disabled, two financial crises unfold simultaneously: the owner's personal income stops, and the business's fixed expenses keep running. BOE insurance addresses the second crisis.

Business Overhead Expense (BOE) insurance reimburses the business for ordinary and necessary operating expenses that continue during the owner's disability. Covered expenses typically include:

Rent or mortgage interest on business premises
Employee salaries and payroll taxes (for non-owner employees)
Utilities, insurance premiums, and professional dues
Equipment leases and maintenance
Legal and accounting fees

What BOE does not cover is equally important: the owner's own salary or personal draw, salaries of employees who perform the same work as the owner (e.g., a co-owner who can still generate revenue), inventory costs, or capital expenditures.

BOE operates as a reimbursement policy: it pays the actual monthly expenses incurred, up to the policy's stated monthly limit. If expenses in a given month are $8,000 and the policy limit is $15,000, the insurer pays $8,000. Unused capacity may roll over to extend the benefit period.

Key features distinguish BOE from personal disability coverage:

Elimination periods are typically short (30–90 days) because businesses cannot absorb operating losses for long
Benefit periods are intentionally brief — usually 12 to 24 months — providing a buffer rather than permanent replacement
Premium tax treatment: BOE premiums are fully tax-deductible as an ordinary business expense; benefits received are taxable (but because the benefits immediately pay for deductible expenses, the net tax impact is typically a wash)

BOE is most relevant for solo or small group practitioners — physicians, dentists, attorneys, consultants — where the owner's absence directly causes revenue loss while overhead continues.

Disability Buy-Sell Funding

Business partnerships face a scenario that life insurance alone does not fully address: one partner becomes permanently disabled. Unlike death, disability is ambiguous — no one knows initially whether the partner will recover in three months or never return. Meanwhile, active partners carry the full operational burden while still sharing profits with an inactive partner. Without a plan, the resulting tension destroys businesses and partnerships alike.

Disability buy-sell funding uses specialized Disability Buy-Out (DBO) insurance to fund the mandatory purchase of a disabled partner's ownership stake when disability becomes permanent. Here is how it works:

Partners execute a buy-sell agreement that defines what constitutes a qualifying disability, establishes the purchase price or valuation method, and obligates the remaining partners (or the entity) to buy and the disabled partner to sell.
A DBO policy is purchased on each owner, with the benefit limit sized to cover their ownership interest.
The DBO policy includes a long elimination period — typically 12 to 24 months — to confirm that disability is permanent rather than temporary.
Once the claim is approved, the policy pays the buyout proceeds, which are used strictly to purchase the disabled partner's equity.
Ownership transfers to the remaining active partners (or the entity), giving the disabled partner cash and giving the business clarity.

Two ownership structures are common:

Cross-purchase: Each partner owns a DBO policy on each other partner. Upon buyout, the purchasing partner receives the benefit and buys the disabled partner's shares directly.
Entity purchase (redemption): The business entity owns and is the beneficiary of policies on all partners. Upon buyout, the entity uses proceeds to redeem the disabled partner's shares.

DBO insurance fills a specific gap that personal disability income insurance and BOE insurance do not address: it is the only product designed to fund the permanent exit of an owner from the business due to disability.

Key Person Disability Coverage

Not every critical employee is an owner. Many businesses have employees — a top revenue producer, a lead engineer, a founder-level executive — whose absence for months or years would cause measurable financial damage even though they have no ownership stake.

Key person disability insurance is purchased and owned by the business, with the business as the beneficiary. If the covered key person becomes totally disabled, the policy pays monthly benefits to the business to help offset:

Lost revenue attributable to the key person
Recruitment and executive search costs
Training costs for a successor or temporary replacement
Overtime and productivity costs absorbed by remaining staff

The benefit is paid to the business — not the individual employee. The employee's personal income needs are addressed by separate personal disability coverage or group LTD. Key person disability coverage addresses the business's financial loss.

The tax treatment mirrors the structure of key person life insurance:

Premiums are generally not tax-deductible (since the policy benefits the business)
Benefits received are generally tax-free to the business (because premiums were paid with after-tax dollars)
