Yes, insurance is generally a deductible business expense. Under Internal Revenue Code Section 162, a business can deduct premiums for any policy that qualifies as an “ordinary and necessary” cost of carrying on its trade or business.1Office of the Law Revision Counsel. 26 USC 162 – Trade or Business Expenses That covers most of what a company buys to protect its operations, employees, and assets. The exceptions matter, though: certain life insurance arrangements, personal-use coverage, premiums tied to construction, and some captive insurance structures either lose the deduction entirely or follow very different rules.
The Test Every Premium Has to Pass
Two questions decide whether a premium is deductible. Is the coverage ordinary, meaning common and accepted in your industry? And is it necessary, meaning helpful or appropriate for your business? The IRS reads “necessary” loosely. Coverage does not have to be legally required or indispensable. It just has to make sense as protection against a real risk your business faces.1Office of the Law Revision Counsel. 26 USC 162 – Trade or Business Expenses
When a policy clears both tests, the premium is generally deductible in the year you pay it. Where it lands on your return depends on your entity: Schedule C for sole proprietors, Form 1120 for C-corporations, Form 1065 for partnerships.
Insurance Premiums You Can Deduct
IRS Publication 535 identifies a wide range of qualifying coverage. Property insurance on buildings, equipment, inventory, and fixtures qualifies, as does general liability coverage against third-party injury or property damage claims. Professional liability and malpractice premiums are deductible for service providers like accountants, attorneys, and consultants. Workers’ compensation, which most states require above a certain employee headcount, is clearly ordinary and necessary.2Internal Revenue Service. Publication 535 – Business Expenses
Business interruption coverage, commercial auto insurance on vehicles used exclusively for the business, fidelity bonds against employee theft, directors and officers (D&O) liability, cyber liability, and credit insurance against business bad debts all qualify on the same basis. The pattern is simple. If the policy protects against a risk the business actually faces, the premium is deductible.
Insurance Premiums You Cannot Deduct
Two categories of coverage are blocked, and both come up often enough to be worth flagging.
Life Insurance Where the Business Is the Beneficiary
Section 264 disallows a deduction for premiums on any life insurance policy where the taxpayer is directly or indirectly the beneficiary.3Office of the Law Revision Counsel. 26 US Code 264 – Certain Amounts Paid in Connection With Insurance Contracts This hits key-person life insurance hardest. The logic: when the insured dies, Section 101 excludes the death benefit from the company’s gross income, so letting the business also deduct the premiums would stack two tax breaks on the same policy.4Office of the Law Revision Counsel. 26 USC 101 – Certain Death Benefits
A workaround exists but shifts who benefits. If the employee names their own family as beneficiary instead of the company, the premium becomes taxable compensation to the employee, and the business deducts it as a wage. You trade the tax-free death benefit for a current deduction.
Personal-Use and Mixed-Use Policies
Insurance on assets not used in the business is never deductible. When a single policy covers both business and personal property, only the business share qualifies. A vehicle used for personal errands and sales calls requires splitting the premium based on documented business-use percentage. Home-office coverage follows the same rule: only the portion allocable to dedicated business space counts.
Health Insurance Depends Heavily on Entity Type
Health insurance is where businesses most often misreport. The method varies by structure, and getting it wrong is a common audit trigger.
C-Corporations
C-corporations get the cleanest result. Premiums the corporation pays for employee coverage, including coverage for shareholder-employees, are fully deductible on Form 1120. Employees receive the coverage tax-free under Section 106.5Office of the Law Revision Counsel. 26 US Code 106 – Contributions by Employer to Accident and Health Plans No special reporting, no owner-income limits.
Sole Proprietors and Single-Member LLCs
Self-employed owners cannot deduct health premiums on Schedule C. They claim the self-employed health insurance deduction as an adjustment to gross income on Schedule 1 of Form 1040, calculated on Form 7206.6Internal Revenue Service. Instructions for Form 7206 – Self-Employed Health Insurance Deduction The deduction lowers income tax but does not reduce self-employment tax.7Office of the Law Revision Counsel. 26 USC 162 – Trade or Business Expenses – Section: Special Rules for Health Insurance Costs of Self-Employed Individuals It is capped at your net earnings from the business sponsoring the coverage, and you can include your spouse, dependents, and children under 27. You cannot claim the deduction for any month you were eligible to participate in a subsidized plan through another employer, including your spouse’s.
S-Corporation Shareholders Owning More Than 2%
S-corp owners above the 2% threshold follow a two-step process. The corporation pays and deducts the premiums, then includes them in the shareholder-employee’s W-2 as wages subject to income tax withholding (though not Social Security or Medicare).8Internal Revenue Service. S Corporation Compensation and Medical Insurance Issues The shareholder then claims the self-employed health insurance deduction on their personal return, offsetting the W-2 inclusion. Both steps have to happen for the math to work.
Partners
When a partnership pays premiums for a partner, the payments are treated as guaranteed payments. The partnership deducts them, the partner reports them as income, and the partner then claims the self-employed health insurance deduction on their 1040.9Internal Revenue Service. Publication 541 (12/2025), Partnerships If the partnership instead reduces the partner’s distributions rather than paying premiums directly, the partnership gets no deduction. The accounting method matters.
Small Employers Without a Group Plan
Businesses with fewer than 50 full-time equivalent employees that do not offer a group plan can set up a Qualified Small Employer Health Reimbursement Arrangement (QSEHRA). Reimbursements for individual-market premiums and medical expenses are deductible to the employer and tax-free to employees who maintain qualifying coverage. For 2026, the caps are $6,450 for self-only and $13,100 for family coverage.10Internal Revenue Service. Revenue Procedure 2025-32 Amounts above those limits are taxable to the employee.
Timing: When You Get the Deduction
The 12-Month Rule on Prepaid Premiums
Businesses sometimes prepay to lock in a rate. A full current-year deduction is allowed only if the coverage period does not extend beyond the earlier of 12 months after the benefit begins, or the end of the following tax year.11eCFR. 26 CFR 1.263(a)-4 – Amounts Paid to Acquire or Create Intangibles A standard 12-month policy paid in December for the following calendar year is deductible in full in the year of payment. A two- or three-year policy fails the test, and the deduction has to be spread across the years benefited.
Premiums During Construction Must Be Capitalized
Insurance premiums paid during the construction or production of a new business asset are not currently deductible. Under the uniform capitalization rules of Section 263A, they get added to the asset’s cost basis.12Office of the Law Revision Counsel. 26 USC 263A – Capitalization and Inclusion in Inventory Costs of Certain Expenses The IRS treats insurance incurred during construction as an indirect production cost.13Internal Revenue Service. Section 263A Costs for Self-Constructed Assets Builder’s risk coverage on a commercial building not yet placed in service is the standard example. Those premiums fold into the depreciable basis and come back through depreciation over the asset’s useful life. Once the building is operational and the policy switches to standard property coverage, premiums become currently deductible.
Self-Insurance and Captives
Setting money aside in a self-insurance reserve does not create a deduction. The IRS treats the reserve as cash you have moved into another pocket, not as an expense. You get the deduction only when the business actually pays a covered loss out of the fund.
Captive insurance, where a business creates its own insurance subsidiary, is harder. Premiums paid to a wholly-owned captive generally are not deductible because the arrangement lacks genuine risk transfer. The parent is paying itself. Premiums can qualify where the captive insures a sufficient number of unrelated parties or meets economic-substance tests. Section 831(b) permits qualifying small captives to elect favorable tax treatment, paying tax only on investment income rather than on premiums received.14Office of the Law Revision Counsel. 26 USC 831 – Tax on Insurance Companies Other Than Life Insurance Companies The IRS scrutinizes captives aggressively, and abusive micro-captive transactions remain on its annual list of tax scams.
What Happens If You Deduct Something You Shouldn’t
Misclassifying a non-deductible premium costs more than the deduction itself. If the error produces an underpayment of tax, the IRS can assess an accuracy-related penalty of 20% of the underpaid amount for negligence or careless disregard of the rules.15Office of the Law Revision Counsel. 26 US Code 6662 – Imposition of Accuracy-Related Penalty on Underpayments Interest runs from the original due date of the return.
The areas that attract the most scrutiny are key-person life premiums deducted as business expenses, personal-use coverage allocated entirely to the business, and captive arrangements without real economic substance. Clean documentation of what each policy covers, how any business-use split was calculated, and why the coverage serves your operations is the simplest protection against a costly adjustment.
