Writing Off Health Insurance When You're Self-Employed: The Deduction, the HSA, and What a Freelancer Actually Saves

What is the self-employed health insurance deduction?

The self-employed health insurance deduction (IRC Section 162(l), reported on Schedule 1 Line 17 of Form 1040) lets you deduct the full cost of health, dental, and qualifying long-term care insurance premiums for yourself, your spouse, and dependents from your gross income. It's an above-the-line deduction, meaning it reduces your Adjusted Gross Income directly — you don't need to itemize to take it, and it lowers your MAGI, which can increase your ACA subsidy. Unlike most medical deductions on Schedule A, there is no 7.5% AGI floor to clear. It's one of the cleanest deductions in the code, and it's specifically designed to level the tax treatment of health insurance between W-2 employees (who get pre-tax premiums via their employer) and self-employed workers.

Who qualifies for the deduction?

You qualify if three conditions are met. First, you must have net self-employment income for the year — reported on Schedule C, Schedule F, or as a partner in a partnership. Second, the deduction is capped at your net self-employment profit (you can't deduct more in health premiums than you actually earned from the business). Third, you must not be eligible for subsidized health coverage through your own or your spouse's employer during the months you're claiming premiums. Note the specific word "eligible" — if your spouse's employer offers coverage but you decline to enroll, the IRS still treats you as eligible and you lose the deduction for those months. S-Corporation owner-employees claim the deduction through a specific mechanism: premiums must be paid by the corporation and included on the owner's W-2 as taxable wages, then deducted on Schedule 1.

• Have net self-employment income for the year (Schedule C, F, or K-1)
• Deduction is capped at your net self-employment profit
• Cannot be eligible for subsidized coverage from your own or spouse's employer
• Applies to health, dental, and qualified long-term care premiums
• Available whether you itemize or take the standard deduction
• S-Corp owners follow a special W-2 inclusion rule

How does the deduction interact with an ACA subsidy?

This is where it gets circular. The premiums you can deduct are only the portion you actually paid out of pocket — meaning your total premium minus the Advance Premium Tax Credit (subsidy) you received. So if your Silver plan costs $700/month and your subsidy covers $500, you can only deduct the $200/month you actually paid. But — and this matters — taking the deduction lowers your MAGI, which increases your allowable subsidy, which changes the deduction amount again. The IRS solves this loop with an iterative worksheet in Publication 974. Tax software handles it automatically. Manually, it's a nightmare. Get a CPA for one year of returns, learn the pattern, and let software drive it thereafter. Skipping the deduction because it's complicated is leaving four figures on the table every year.

What premiums can I include in the deduction?

Broader than most freelancers realize. Included: health insurance premiums for yourself, your spouse, dependents, and any child under age 27 (even if not a dependent). Dental insurance premiums. Vision insurance premiums when purchased as a standalone plan. Qualified long-term care insurance premiums, subject to age-based caps ($480 to $6,020 depending on age). Medicare Part B, Part D, and Medicare Advantage premiums if you're 65+ and still self-employed. Not included: expenses paid from HSA funds (already tax-advantaged, no double dip), premiums subsidized by an employer, cosmetic or elective procedures not covered by insurance, and any premiums exceeding your net self-employment income for the year.

Should I layer an HSA on top of the deduction?

If you're on a High Deductible Health Plan (HDHP), yes — nearly always. HSA contributions are a separate above-the-line deduction on top of your health insurance deduction. In 2026 you can contribute $4,400 individual or $8,750 family, plus a $1,000 catch-up if you're 55+. That's another $1,000–$2,600 in federal tax savings depending on your bracket, and the money grows tax-free and comes out tax-free for qualified medical expenses. For a healthy self-employed person, the ideal move is to maximize HSA contributions each year, pay current medical expenses out of pocket rather than from the HSA, save the receipts, and let the HSA grow like a retirement account. Decades later, you can reimburse yourself for those old receipts tax-free, or use the funds like a Traditional IRA after age 65.

What are the most common mistakes on this deduction?

Four recurring errors we see when clients bring us their prior-year returns. One: deducting the sticker-price premium instead of the post-subsidy amount actually paid. Two: taking the deduction in a year when a spouse was eligible for employer coverage, even for a single month — the deduction is calculated month by month. Three: forgetting dental and vision premiums, which qualify but often get missed because they're separate policies. Four: S-Corp owners who pay premiums personally instead of through the corporation, breaking the required W-2 inclusion rule and losing the deduction entirely. Consult a licensed tax professional to review your setup, especially in the first year you claim this deduction. The math is worth it, but the paperwork rules are strict.
