Business Insurance
Protecting your business is a necessary cost of doing business. General liability, malpractice, E&O, and cyber insurance premiums are fully deductible — but health insurance is a different story.
A guide by Taxstra Tax & Accounting — CPA-led tax strategy for business owners
Line 15 covers premiums for insurance policies that protect your business operations. General liability, professional liability (E&O), malpractice, cyber insurance, workers' compensation, and business property insurance all belong here. Personal insurance — your own health plan, personal life insurance — does not.
What Belongs on Line 15
| Insurance Type | Deductible? | Notes |
|---|---|---|
| General Liability (GL) | Yes — Line 15 | Core business coverage |
| Professional Liability / E&O | Yes — Line 15 | Essential for service providers |
| Malpractice Insurance | Yes — Line 15 | Required for medical/legal professionals |
| Cyber Security Insurance | Yes — Line 15 | Growing in importance |
| Workers Compensation | Yes — Line 15 | Required if you have W-2 employees |
| Business Property (Fire/Theft) | Yes — Line 15 | Deductible; insurance proceeds are taxable |
| Personal Health Insurance | No — Form 1040 Sch. 1 | Adjustment to income, not Sch. C |
| Personal Life Insurance | No — never deductible | Owner is the beneficiary |
| Vehicle Insurance (actual method) | No — Line 9 (Car/Truck) | Part of vehicle expense, not Line 15 |
The Health Insurance Confusion
The placement of health insurance deductions confuses even experienced business owners. Here is the complete picture:
Why It Matters Where It Goes
Deductions on Schedule C reduce both income tax and self-employment tax (15.3%). Deductions taken on Schedule 1 (as an adjustment to income) reduce only income tax. Health insurance on the right line is worth less per dollar than a true business deduction on Line 15.
The Profit Limit
You can only deduct self-employed health insurance premiums up to the amount of your net profit from the business. You cannot use the health insurance deduction to create or increase a loss.
Do Not Put Personal Health Insurance on Line 15
Some preparers mistakenly deduct the owner's personal health insurance on Schedule C Line 15. This artificially lowers self-employment income and reduces SE tax — which the IRS flags as improper. Personal health insurance for a sole proprietor belongs on Form 1040 Schedule 1, Line 17. Period.
Modern Coverage Worth Knowing About
Cyber Liability Insurance
Ransomware attacks, data breaches, and client notification costs are an increasingly real risk for businesses of every size. Cyber liability premiums are 100% deductible. Coverage typically includes data recovery, legal fees, regulatory fines, and PR costs after a breach.
Business Interruption Insurance
Pays for lost income if your business is forced to close due to a covered event (fire, pipe burst). Premiums are deductible. Important caveat: if you receive a business interruption payout, that proceeds are taxable income — you are replacing taxable revenue.
The 12-Month Rule for Prepaid Policies
Businesses sometimes pay multi-year insurance premiums upfront to lock in a lower rate. The tax treatment depends on the term.
The 12-Month Rule: You can deduct a prepaid expense in full if the benefit period does not extend beyond 12 months from the first date of benefit.
The Mistake: Paying a 3-year insurance premium in one lump sum ($3,600) at year-end and deducting it all in Year 1. Only roughly $1,200 (Year 1's portion) is deductible this year. The remaining $2,400 must be amortized over the remaining policy term.
