Ordinary and necessary insurance for your business is a deductible expense. That covers general liability, professional liability or errors-and-omissions coverage, property and equipment insurance, business interruption insurance, and specialized policies your trade requires.
Business auto insurance is deductible when you use the actual-expense method for your vehicle, as part of your total vehicle costs times the business-use percentage. If you use the standard mileage rate instead, insurance is already built into that rate, so you do not deduct it separately.
Health insurance is handled differently. Self-employed health insurance premiums are not a Schedule C expense; they are an above-the-line adjustment on Schedule 1. Keep them separate from your business liability and property insurance.
Personal insurance does not qualify. Personal life insurance, and the personal portion of any policy, are not business deductions. Keep your business policy documents and premium records so the deduction is easy to support.
