If you're self-employed and paying your own health insurance premiums, the tax code hands you one of the better deals available to freelancers: an above-the-line deduction that reduces your taxable income without requiring you to itemize. It's claimed on Form 7206, and it's capped at a specific figure -- your net self-employment earnings, not your raw profit. This calculator applies that cap so you know how much of what you paid is actually deductible.
How it works
The deduction is the lesser of two numbers: what you actually paid in premiums, or your net self-employment earnings for the year. That earnings figure isn't your Schedule C profit as-is -- it's your net profit minus the deductible half of your self-employment tax, and minus any contributions you made to a self-employed retirement plan (SEP-IRA, solo 401(k), and similar) tied to that business. Those two subtractions matter because they're also above-the-line deductions competing for the same pool of earned income, and the health insurance deduction only gets what's left after them.
If your earnings limit comes out at or below zero -- a thin-margin year, a business loss, or retirement contributions that eat the whole profit -- your deduction floors at $0, no matter how much you paid in premiums. Whatever premiums don't fit under the limit are reported separately here as unused premiums: not lost forever, since they may still be deductible as an itemized medical expense subject to the 7.5%-of-AGI floor on Schedule A, but not part of this above-the-line deduction.
Worked example
Say you paid $9,000 in annual premiums, your net self-employment profit was $60,000, the deductible half of your SE tax was $4,239, and you made no retirement contributions.
- Earnings limit: $60,000 − $4,239 − $0 = $55,761
- Deduction: the lesser of $9,000 and $55,761 = $9,000
- Unused premiums: $9,000 − $9,000 = $0
Your earnings comfortably clear the premiums here, so the full amount is deductible. Drop that net profit to something closer to your premium total -- say a leaner year, or heavier retirement contributions -- and the earnings limit can bind instead, leaving part of what you paid unclaimed above the line.
How to interpret your result
The deduction figure is what goes on Form 7206 and flows to Schedule 1 as an adjustment to income -- it lowers your income tax, but it does not reduce your self-employment tax, since SE tax is calculated on net earnings before this deduction applies. If unused premiums show a nonzero number, that's the gap between what you paid and what the earnings cap let you claim above the line; it doesn't vanish, but it moves to a different, less favorable part of the return (itemized medical expenses, if you clear the AGI floor and itemize at all).
One rule this calculator can't check for you: the no-double-dip provision. You can't claim this deduction for any month you, or your spouse if you file jointly, were eligible to enroll in an employer-subsidized health plan -- through your own job, a spouse's job, or otherwise. Eligibility is what disqualifies you, not enrollment, so back out premiums for any month that applies before you plug in a number here.
This tool is also deliberately simplified in one specific way: it does not run the ACA Premium Tax Credit reconciliation. If your coverage comes through the marketplace and you also claim a premium tax credit, the credit and this deduction affect each other in a circular calculation the IRS handles with an iterative worksheet. That's genuinely fiddly math, and getting it wrong either overstates your deduction or misstates your credit. If that applies to you, work through the real worksheet or bring it to a preparer rather than trusting this number as final.
Methodology & sources
earningsLimit = round2(max(0, netSelfEmploymentProfit − halfSelfEmploymentTax − retirementContributions)); deduction = round2(min(annualPremiums, earningsLimit)); unusedPremiums = round2(max(0, annualPremiums − deduction)). Every output is rounded to the cent from unrounded intermediate math, so the three figures stay internally consistent.
This models the core mechanics of the IRS Form 7206 instructions and the self-employed health insurance rules summarized in IRS Publication 535, simplified as noted above: no ACA premium tax credit reconciliation, and no automatic check of the employer-plan-eligibility exclusion. It covers US federal tax only and is not a substitute for the actual form, a full return, or advice from a tax professional -- it's a planning estimate, not a filed number.
