Is Insurance a Business Expense? IRS Rules and Deductible Premiums

Yes, insurance is generally a deductible business expense. Under Internal Revenue Code Section 162, premiums for coverage that is “ordinary and necessary” to your trade or business can be written off in the year you pay them.¹ The important exceptions are life insurance policies where the business is the beneficiary, coverage on personal-use property, premiums paid during construction of a new asset, and health insurance, which follows a separate set of rules that depend on how your business is organized.

The Rule That Governs Every Insurance Deduction

Section 162 sets a two-part test. The premium has to be “ordinary,” meaning common and accepted in your line of work, and “necessary,” meaning helpful or appropriate for the business. Necessary does not mean legally required or unavoidable. Coverage against a foreseeable risk to your operations or revenue usually clears the bar.¹

If a policy passes both parts and insures assets or activities used in the business, you deduct the full premium on the return that matches your entity: Schedule C for a sole proprietor, Form 1065 for a partnership, Form 1120 for a C-corporation.

Premiums You Can Deduct

IRS Publication 535 lays out the categories that qualify, and the list is broad.² If the coverage protects against a risk your business actually faces, the premium is almost certainly deductible.

Property insurance on buildings, equipment, inventory, and fixtures used in the business.
General liability coverage for third-party bodily injury and property damage claims.
Professional liability and malpractice coverage for accountants, attorneys, consultants, and similar service providers.
Workers’ compensation, which most states require above a certain employee count.²
Business interruption insurance covering lost income and fixed costs during a covered shutdown.
Commercial auto insurance on vehicles used exclusively for business.
Fidelity bonds against employee theft or dishonesty.
Directors and officers (D&O) liability coverage.
Cyber liability coverage for data breach response and related lawsuits.
Credit insurance against losses from business bad debts.

Premiums You Can’t Deduct

Life Insurance With the Business as Beneficiary

Section 264 blocks a deduction for any life insurance premium if the taxpayer is directly or indirectly the beneficiary of the policy.³ Key-person coverage is the usual example. When the insured dies, Section 101 excludes the death benefit from the company’s gross income, so a deduction for the premiums would stack two tax breaks on the same policy.⁴

There is a way around it. If the employee names their own family as beneficiary, the premium becomes taxable compensation to the employee and deductible by the business as wages. The company loses the tax-free death benefit but picks up a current deduction.

Personal and Mixed-Use Coverage

Insurance on assets not used in the business is not deductible at all. When a single policy covers both business and personal property, only the portion tied to business use qualifies. A vehicle driven both personally and for work has to be split by documented business-use percentage, and the same allocation applies to home-office coverage.

Self-Insurance Reserves

Setting cash aside in a self-insurance reserve does not produce a deduction. The IRS treats the reserve as money you still have. You claim the loss when you actually pay a covered claim from the fund, not when you fund it.

Health Insurance Follows Different Rules

Health coverage is deductible, but where and how you claim it depends on your entity. Getting the reporting wrong on this one is a common audit trigger.

C-Corporations

A C-corporation deducts premiums it pays for employee health coverage, including coverage for shareholder-employees, directly on Form 1120. Employees receive the coverage tax-free under Section 106.⁵

Sole Proprietors and Single-Member LLCs

You do not deduct your own health insurance on Schedule C. Instead, you claim the self-employed health insurance deduction as an adjustment to gross income on Schedule 1, calculated on Form 7206.⁶ The deduction reduces income tax but not self-employment tax.⁷

The write-off is capped at the net earnings of the business that sponsors the coverage. You can include your spouse, dependents, and children under 27. You cannot claim it for any month you were eligible for a subsidized plan through another employer, including your spouse’s.

More-Than-2% S-Corporation Shareholders

The corporation pays and deducts the premium, then adds it to the shareholder-employee’s W-2 as wages subject to income tax withholding (though not Social Security or Medicare).⁸ The shareholder then claims the self-employed health insurance deduction on their personal return, which cancels out the income inclusion. Both halves have to happen.

Partners

When a partnership pays a partner’s premiums, the payment is treated as a guaranteed payment. The partnership deducts it, the partner reports it as income, and the partner claims the self-employed health insurance deduction to offset it.⁹ If the partnership just reduces a partner’s distributions rather than paying the premium directly, the partnership loses the deduction.

Long-Term Care Premiums Have Age-Based Caps

Qualified long-term care insurance is deductible under the same rules as health insurance, but only up to an amount that rises with the insured person’s age. For 2026:

Age 40 or under: $500
Age 41 to 50: $930
Age 51 to 60: $1,860
Age 61 to 70: $4,960
Age 71 and older: $6,200

Anything above the cap for your bracket is not deductible. The IRS adjusts the figures annually.

Prepaid and Multi-Year Policies

Prepaying premiums does not automatically accelerate the deduction. Under the 12-month rule, you can deduct a prepaid premium in full only if the coverage does not extend beyond the earlier of 12 months after the benefit begins or the end of the following tax year.¹⁰

A standard 12-month policy paid in December for coverage running the next January through December usually qualifies. A two-year or three-year policy does not. You have to spread the deduction across each year the coverage protects you.

Premiums Paid During Construction

Insurance carried while you are building or producing a new business asset is not a current expense. The uniform capitalization rules of Section 263A treat those premiums as indirect production costs, so you add them to the asset’s basis and recover them through depreciation.¹¹¹² Builder’s risk insurance on a commercial building that has not been placed in service is the classic case. Once the building is operational and you replace the builder’s risk policy with standard property coverage, the new premiums become currently deductible.

What a Wrong Classification Costs

If misclassifying an insurance premium creates an underpayment, Section 6662 allows the IRS to add an accuracy-related penalty of 20% of the underpaid tax, plus interest running from the original due date.¹³ The penalty applies to negligence and careless disregard of the rules, not just outright fraud.

The categories that draw the most attention on audit are key-person life insurance premiums claimed as deductions, mixed-use policies allocated entirely to the business, and captive insurance arrangements without real risk transfer. Clean records of what each policy covers, how you calculated any business-use split, and why the coverage protects the business will handle almost every question an examiner is likely to raise.
