The Self-Employed Health Insurance Deduction: What It Doesn't Cover

Freelancers who pay for their own health insurance assume the write-off works like any other business expense: pay the premium, subtract it from taxable income, done. The real version sits on a different line of your tax return, carries a ceiling tied to your profit, and leaves your self-employment tax bill exactly where it was.

Two traps catch freelancers on this deduction every year. A freelancer with $70,000 in family premiums can lose thousands of it to a profit ceiling they never checked. A freelancer married to someone with an employer health plan can lose the deduction for months at a stretch, even without ever touching the spouse's plan. Both traps live on the same IRS form, and both are easy to dodge once you know where they sit.

1.What This Deduction Actually Changes

Pay your own health insurance and the IRS lets you deduct the premiums on Schedule 1, line 17 (the form for income adjustments, separate from Schedule C). Sole proprietors, single-member LLC owners, partners, and anyone who owns more than 2% of an S-corp can claim it, as long as the business shows a profit. S-corp owners have a different ceiling, the W-2 wages the S-corp paid them, instead of net profit.

The deduction covers premiums for yourself, your spouse, your dependents, and any child of yours under 27, even if you don't claim that child as a dependent. Form 7206 is the current IRS worksheet for figuring the number. You're required to file it if you had more than one business subject to self-employment tax, filed Form 2555 for foreign income, or are counting long-term care premiums toward the deduction.

2.The Ceiling Is Your Profit, Not Your Premium

The deduction can't be larger than the net profit from the business the coverage is tied to. The IRS doesn't stop at profit, either. Before comparing your premiums to that number, you subtract the deductible half of your self-employment tax and any SEP-IRA, SIMPLE, or solo 401(k) contribution you made for the year. Whatever is left is your ceiling.

Three things shrink the ceiling before it ever meets your premiums:

• Net profit. Only from the specific business the health coverage is connected to, not your household income as a whole.
• The deductible half of self-employment tax. The IRS lets you write off half of the 15.3% you pay, and that write-off comes out of the ceiling before your premiums do.
• Retirement contributions. A SEP-IRA, SIMPLE IRA, or solo 401(k) contribution for the same year reduces the ceiling further.

Say you netted $50,000 on Schedule C. Your deductible half of self-employment tax comes to about $3,500. You put $4,000 into a SEP-IRA. Subtract both from your profit and the ceiling lands at $42,500. Pay $9,000 a year for a family plan and you deduct all of it, well under the ceiling. Pay $48,000 for a pricier family plan in a high-cost state and you only get to write off $42,500 of it. The rest carries over to nowhere. It just goes unclaimed for the year.

3.The Spousal Coverage Rule Checks You Month by Month

The IRS checks eligibility one month at a time, not once for the whole year. For any month you or your spouse could have joined an employer-subsidized health plan, even a plan you never touched, you lose the deduction for that month's premiums. Eligibility is what disqualifies you, not enrollment. Turn down a spot in your spouse's plan in June because you prefer your own coverage, and June's premium still drops out of the deduction.

Most freelancers don't track this month by month. They hand their accountant one total for the year and let the software sort it out, or they round up and hope it settles on its own. Will Rogers wrote about the income tax in 1923 and said it made more liars out of the American people than golf has. A rule that depends on remembering which specific months your spouse could have added you to a plan invites exactly that kind of guessing.

This deduction moves your income tax bill. Your self-employment tax bill does not move at all.

4.Long-Term Care Premiums Get Their Own Ceiling

Long-term care insurance premiums count toward this deduction too, but only up to a limit set by your age on December 31, not by what you actually paid. The IRS raises the limit most years. For 2026 it rose about 3% from the year before.

Married couples get to use this twice. Each spouse's age and each spouse's policy get checked on their own, so a 55-year-old and a 65-year-old with separate long-term care policies use two different rows of the table, not one.

5.Buying Through the Marketplace Adds a Second Moving Number

Buy your health insurance through an ACA marketplace instead of straight from an insurer, and a second number enters the math: the premium tax credit (a subsidy that lowers your monthly premium based on income). This deduction lowers your income. A lower income can raise your premium tax credit. A bigger premium tax credit lowers what you actually paid out of pocket, which lowers what you have left to deduct. Each number changes the other.

The IRS has a worksheet for this circular math in Publication 974. Most tax software runs it automatically now and lands on the right pair of numbers without you seeing the loop. Fill it out by hand and expect to run the calculation more than once before both numbers agree with each other.

6.How to Check Your Own Number

Four steps get you a real figure instead of a guess:

1. Add up premiums paid for medical, dental, vision, and any long-term care coverage, using the age-based cap from the table above.
2. Check every month of the year for spousal or dependent eligibility for an employer-subsidized plan, and drop any month that disqualifies you.
3. Work out your ceiling: net profit from the business, minus the deductible half of your self-employment tax, minus retirement contributions for the year.
4. Take the smaller of your adjusted premium total and your ceiling. That number goes on Schedule 1, line 17.

The QBI deduction works the same way underneath the surface. It looks like a flat 20% off qualified profit until two limits most freelancers never check start cutting it down, a pattern the QBI deduction guide walks through in full.

The self-employed health insurance deduction is worth claiming every year you qualify for it. Just don't expect it to touch the 15.3% you pay for Social Security and Medicare on your net earnings. It only ever moves your income tax, and only up to whatever ceiling your profit and retirement contributions leave standing.
