Most freelancers overpay their taxes because they leave money on the table. One of the biggest missed deductions is health insurance. If you buy your own coverage because you don’t have a boss handing you a plan, you can likely write off 100% of what you pay in premiums. Not 50 percent. Not a portion. All of it. And unlike most deductions, you don’t even need to itemize to claim it.

Here’s exactly how the self-employed health insurance deduction works, who qualifies, and how to claim it without triggering problems with the IRS.

What the self-employed health insurance deduction actually is

The self-employed health insurance deduction lets you subtract the full cost of your medical, dental, and qualified long-term care premiums from your income before you calculate income tax.

It’s what the IRS calls an “above-the-line” deduction. That means it’s an adjustment to income, reported on Schedule 1 of your Form 1040. You don’t have to itemize on Schedule A to get it. You take the standard deduction and this deduction on top of it.

That distinction matters. Most people who buy insurance can only deduct medical costs if they itemize and only after those costs pass 7.5 percent of their adjusted gross income. As a freelancer, you skip that hurdle entirely.

Who qualifies

To claim this deduction, you generally need to meet three conditions.

First, you have to be self-employed with a net profit. That includes sole proprietors filing Schedule C, single-member LLC owners, partners in a partnership, and more-than-2-percent shareholders in an S corporation. If you’re a 1099 contractor, you almost certainly fall into this group.

Second, you must have a business profit. The deduction cannot exceed your net self-employment income for the year. If your Schedule C shows $30,000 in profit, your deduction is capped at $30,000. If your business shows a loss, you get nothing this way. You’d have to fall back on itemizing.

Third, the policy has to be established under your business. For sole proprietors, the IRS is flexible here. The policy can be in your own name rather than your business name and still qualify. What matters is that you paid for it and weren’t reimbursed.

Whose premiums you can deduct

You can deduct premiums for coverage that includes you, your spouse, your dependents, and any child of yours who was under age 27 at the end of the year.

That last point is worth repeating. The child does not have to be your tax dependent. If you have a 25-year-old kid on your health plan who files their own return, their premiums still count toward your deduction.

Qualifying premiums include:

• Medical insurance
• Dental insurance
• Vision insurance
• Qualified long-term care insurance, up to age-based limits

Long-term care premiums have a cap that rises with age and adjusts for inflation each year. For 2026 the limits fall in roughly these ranges: around $480 if you’re 40 or younger, around $900 for ages 41 to 50, about $1,800 for ages 51 to 60, roughly $4,800 for ages 61 to 70, and about $6,000 if you’re 71 or older. These figures nudge up slightly each year, so check the current IRS numbers when you file.

The rule that trips most freelancers up

Here is the single biggest catch, and it costs people the deduction every year.

You cannot deduct premiums for any month you were eligible to participate in a subsidized health plan through an employer. This applies to your own employer and, critically, your spouse’s employer.

Read that again. If your spouse works a W-2 job and could have added you to their employer’s plan, you lose the deduction for those months even if you turned the coverage down and bought your own instead.

The test is eligibility, not enrollment. It doesn’t matter whether you actually signed up. If the door was open and the employer subsidized the plan, that month is disqualified.

This is calculated month by month. Say you freelanced full time from January through August, then your spouse started a job in September that offered you coverage. You could still deduct eight months of premiums, January through August.

How to calculate your deduction

Start with the total premiums you paid during the year for qualifying coverage. Subtract any amount you were reimbursed and any premium tax credit you received through the marketplace.

That last piece matters if you bought insurance on healthcare.gov or a state exchange and got a subsidy. You can only deduct the portion you actually paid out of pocket, not the amount the government covered through the advance premium tax credit.

This creates a circular calculation, because your deduction affects your income, which affects your premium tax credit, which affects your deduction. The IRS provides worksheets to handle this loop, and most tax software runs it automatically.

Then apply the two limits already covered:

• Your deduction cannot exceed your net self-employment profit.
• Months of employer eligibility are excluded.

One more limitation people forget: this deduction reduces your income tax, but it does not reduce your self-employment tax. Self-employment tax runs 15.3 percent on your net earnings and is calculated before this deduction comes into play. So the health insurance deduction saves you at your income tax rate, but your 15.3 percent Social Security and Medicare bill stays the same.

How to actually claim it

For your 2025 and later returns, you calculate the deduction on Form 7206, “Self-Employed Health Insurance Deduction.” This form replaced the old worksheet that used to live in the Schedule C instructions.

Form 7206 walks you through your total premiums, the limitations, and the marketplace subsidy adjustment if one applies. The final number flows to Schedule 1, Line 17, “Self-employed health insurance deduction.”

From there it reduces your adjusted gross income on your Form 1040. A lower AGI can have ripple benefits too, since AGI drives eligibility for other credits and phaseouts.

If you’re an S corporation shareholder, the mechanics differ. Your premiums must be paid by the corporation and included in your W-2 wages as taxable compensation. You then deduct them personally. Skip that W-2 step and the IRS can deny the deduction, so coordinate with your payroll setup.

Common mistakes to avoid

Don’t double-dip. If you deduct a premium here, you cannot also claim it as a medical expense on Schedule A. Pick one, and this one is almost always better.

Don’t include the same dollars twice. Marketplace subsidies you didn’t pay for don’t count. Only your out-of-pocket premiums qualify.

Don’t forget the spouse rule. Check every month against your spouse’s employer coverage. Getting this wrong is one of the most common reasons the deduction gets challenged.

Don’t ignore recordkeeping. Keep your premium statements, Form 1095-A if you used the marketplace, and proof of payment. If you write off $6,000 in premiums, you want the paper trail to back it up.

And keep this deduction separate in your head from your other freelance write-offs. Your mileage at $0.725 per business mile in 2026, your home office, your software subscriptions, and your health premiums are all different lines with different rules. Lumping them together is how numbers get lost.

The bottom line: if you pay for your own health coverage as a freelancer, this is one of the most valuable deductions available to you. A $600 monthly premium adds up to $7,200 a year off your taxable income. At a 22 percent bracket, that’s about $1,584 back in your pocket, just for filling out one extra form.
