Self-Employed Health Insurance Deduction

Health cover is the largest cost most freelancers carry alone. Here is how much of it the tax code gives back — and the two limits that catch people out.

How this is calculated

You may deduct health, dental, vision and qualified long-term care premiums for yourself, your spouse, your dependents and any child under 27 — but only for months you were not eligible for a subsidised employer plan through your own or a spouse's job, and only up to your earned income from the business (profit less the deductible half of self-employment tax and any retirement contributions). Critically, it is an adjustment to income, not a business expense, so it never reduces self-employment tax.

Worked example: $9,600 of premiums on $70,000 of profit with no employer coverage available is fully deductible. In the 22% bracket that saves about $2,112 of income tax — and $0 of self-employment tax.

The rule everyone gets wrong

Almost every other business expense reduces your profit, which cuts both income tax and self-employment tax. The health insurance deduction does not. It is an adjustment to income taken on Schedule 1, not a business expense on Schedule C, and the Form 7206 instructions are explicit: you cannot subtract it when figuring net earnings for self-employment tax.

The practical consequence is that $9,600 of premiums saves roughly $2,100 in the 22% bracket, not the $3,400 you would get from an ordinary business deduction of the same size. Calculators that apply a blended rate to this deduction overstate the benefit by more than half, which matters when you are deciding how much to set aside.

The monthly employer test

You cannot claim premiums for any month in which you were eligible to join a subsidised health plan through an employer — yours or your spouse's. Eligibility alone disqualifies the month; declining the coverage does not help. If you left a job in April and went freelance, only the months from May onward count, and the calculator above scales your premiums accordingly.

This catches two groups in particular: freelancers whose spouse has employer cover they have turned down, and people who freelance alongside a part-time job that offers a plan. In both cases the deduction can be zero even though the premiums are entirely real.

The earned income ceiling

The deduction cannot exceed the earned income of the business the plan is established under — your net profit reduced by the deductible half of self-employment tax and by any self-employed retirement contributions. In a slow year with high premiums, this is the limit that bites, and unlike Section 179 the excess does not carry forward. It is simply lost.

That interaction is worth planning around. A large Solo 401(k) contribution reduces the earned income ceiling, so in a marginal year an aggressive retirement contribution can quietly wipe out part of your health insurance deduction. Our retirement plan calculator shows the contribution side of that trade.

What counts as a premium

Medical, dental and vision premiums all qualify, as do qualified long-term care premiums up to age-based limits. Cover can include your spouse, your dependents and any child under 27 at year end — even a child who is not your dependent, which is a genuinely useful and little-known provision. Marketplace plans qualify; if you also received a premium tax credit, only the portion you actually paid is deductible.

What does not qualify: anything reimbursed, general health expenses that are not premiums, and cover for months disqualified by the employer test. Ordinary medical bills are a separate matter entirely — those go to itemised deductions and only above a percentage of income, which is why most people never benefit from them.

Frequently asked questions

Does the health insurance deduction reduce self-employment tax?

No, and this is the most misunderstood point. Form 7206's instructions state you can't subtract it when figuring net earnings for self-employment tax. It reduces income tax only, so it's worth roughly half what an ordinary business expense of the same size would be.

What if my spouse has employer coverage I declined?

You're still disqualified for every month you were eligible to join it. Declining doesn't restore the deduction — the test is eligibility, not enrolment.

Can I deduct premiums for my adult child?

Yes, for a child under 27 at the end of the year, even if that child isn't your dependent and isn't on your tax return. It's one of the more generous and least known parts of the rule.

What if my premiums exceed my business profit?

The deduction is capped at your earned income from the business — profit minus the deductible half of SE tax and any retirement contributions — and the excess is lost rather than carried forward.

Do marketplace plans qualify?

Yes. If you also received a premium tax credit, only the amount you actually paid out of pocket is deductible, since the credit already covered the rest.

Where do I claim it?

On Schedule 1 of Form 1040 as an adjustment to income, with Form 7206 used to compute it. Because it's above the line, you get it whether or not you itemise.
