If your business would miss payroll, lose its biggest client, or default on a loan because one person didn't show up tomorrow — that person is a key person, and you are uninsured risk.
Key person life insurance (often called key man insurance) is not a perk. It is a contract where the business owns a life and often disability policy on an owner, founder, or irreplaceable employee. If that person dies or becomes totally disabled, the business receives the death benefit, not the family. The money replaces lost revenue, hires a successor, and keeps a lender from calling the loan.
This guide explains what key person coverage actually does, when a bank will require it, the tax trap that surprises most owners, and how to size coverage without overpaying.
Who Is a Key Person?
A key person is anyone whose death or disability would cause a measurable financial loss. Common examples in small businesses:
- The owner who holds customer relationships. A consulting firm where clients buy the founder's expertise, not the logo.
- The technical founder who is the product. A SaaS company where only one person can ship critical code or holds the patent.
- The rainmaker. A sales leader who brings 40% of revenue, or a chef whose name fills seats.
- The operator who is the bank's comfort. A contractor whose license, bonded status, or personal guarantee supports the credit line.
If you have a loan, a lease, or a major contract that names an individual, that individual is probably the key person your lender is thinking about.
What the Policy Covers — and What It Doesn't
Key person insurance is typically term life, sometimes paired with disability coverage. The business is the owner, premium payer, and beneficiary. The insured is the key person, who must consent and take a medical exam.
Covered: Death from any cause not excluded in the policy (suicide within the first two years is often excluded), and, if you add a rider, total disability that prevents the person from working. The benefit is paid in a lump sum.
Not covered: Voluntary departure, retirement, or a competitor hiring the person away. If your key person quits, the policy does not pay — it just becomes an asset you can surrender or keep.
How the money is used is unrestricted, but sound plans earmark it:
- 6–12 months of operating losses while revenue stabilizes
- Cost to recruit, hire, and train a replacement (executive search fees alone can be 25–35% of first-year salary)
- Debt service if a loan requires key person protection
- Contractual obligations, like completing a bonded project
A $500,000 benefit sounds large until you map it: $180,000 in lost gross profit, $80,000 in search and onboarding, $120,000 in debt coverage, and the rest in training and transition.
When a Lender Requires It
Banks often require key person insurance as a condition for a term loan, line of credit, or SBA 7(a) loan. The requirement is not about your health — it is about collateral.
Collateral assignment: The business assigns the policy to the lender as additional collateral. If the key person dies, the lender is paid first from the proceeds up to the outstanding loan balance; the remainder goes to the business.
Typical triggers for a requirement:
- SBA loans over $350,000 where repayment depends heavily on one person's expertise or relationships
- Commercial real estate loans where the guarantor is also the operator
- Lines of credit that would be unsecured without the personal guarantee of the key person
Amount required: Often the lender asks for coverage equal to the loan balance, or 1× to 1.5× the balance for term loans. For a $750,000 SBA loan, expect a $750,000–$1,000,000 term requirement. The lender will require annual proof of premium payment and that the assignment is on file with the insurer.
If you switch lenders or pay off the loan, remember to remove the assignment. Many businesses leave a bank as assignee for years after the loan is gone.
The Tax Trap: Premiums Are Not Deductible
This is the mistake that shows up on audit. Key person life insurance premiums are not deductible as a business expense when the business is the beneficiary. The IRS treats the premium as a capital outlay, not an ordinary and necessary expense, because the business will receive the tax-free death benefit.
Death benefit is generally income-tax free to the business when received, under Section 101(a). That is the trade-off: no deduction going in, no tax coming out.
Cash value growth in a permanent policy is tax-deferred, but loans or withdrawals can trigger tax if mishandled.
Disability premiums are different: if the business pays disability premiums and the benefit would be taxable to the business, the premium may be deductible. That analysis depends on who is taxed on the benefit. Get a written determination from your CPA before deducting.
Documentation for your books: Book the premium as Other Non-Deductible Expense or Key Person Insurance — Non-Deductible, not as Insurance Expense. That flag keeps your tax preparer from accidentally deducting it and keeps your P&L honest about true operating cost.
How Much Coverage Do You Actually Need?
Agents often quote multiples of salary — 5× to 10× — but a business should use a contribution method:
- Revenue contribution: What percentage of revenue is directly tied to the person? If the rainmaker brings $600,000 of $1.5 million in revenue and the business runs at 20% net margin, the gross loss from that relationship is $600,000, and the profit at risk is $120,000 per year.
- Replacement cost: What will it cost to find and ramp a successor for 12–18 months? Include search fees, signing bonus, training, and lower productivity during ramp.
- Debt at risk: What loan balance would become shaky if the person left? That is the lender's number.
- Contractual risk: Are there contracts that allow the customer to terminate if the key person leaves or dies?
Example for a 12-person contractor: Owner-operator is the license holder and estimator, revenue $2.8M, profit $340K. Replacement estimator takes 9 months at $95K salary plus $40K in recruiting and backlog delay costing $120K. Loan $500K with key person assignment. A $750K 10-year term policy covers the loan plus transition, at a cost of roughly $60–$120 per month for a healthy 40-year-old. That is cheaper than the business interruption it insures.
Review coverage annually alongside your loan covenants and revenue concentration. If the key person's contribution falls from 40% to 15% because you diversified, reduce coverage and save premium.
Buying Without Overpaying or Under-Documenting
- Term vs. permanent: Most small businesses use level term (10, 15, or 20 years) matched to the loan term or the expected tenure of the key person. Permanent insurance with cash value is rarely needed for pure protection and costs 5–10× more.
- Medical and ownership: The business must be the applicant and owner; the employee must consent in writing, including the coverage amount and that the business is the beneficiary. The notice and consent requirement (Section 101(j)) must be met before the policy is issued, or the death benefit can become taxable.
- Buy-sell vs. key person: Do not confuse key person insurance with buy-sell insurance. Buy-sell funds the purchase of a deceased owner's shares by the surviving owners or the company. Key person compensates the business for economic loss. You may need both, but they are separate policies with different owners and beneficiaries.
- Continuity plan: The policy is not the plan. Write a one-page key person continuity plan: who does what in the first 30 days, which clients get a call, which hiring firm is on retainer, and how the proceeds will be allocated. Give a copy to the lender if they require it.
Keep Your Finances Organized From Day One
Key person risk is concentrated in the least documented part of many small businesses: the importance of one human. Insurance quantifies it, but your books make the requirement credible to a lender and the tax treatment clean at year-end.
