Schedule 1 Line 17: Self-Employed Health Insurance Deduction

Schedule 1, Line 17 is where a self-employed filer enters the self-employed health insurance deduction: premiums paid during the year for medical, dental, vision, Medicare, and qualified long-term care coverage, subtracted from income before tax is calculated. The amount is capped at the net profit of the business that established the plan, and you arrive at it by completing Form 7206 and carrying the result to Line 17.¹ The total from Part II of Schedule 1 then flows to Form 1040 and reduces your adjusted gross income.²

Who Can Claim the Line 17 Deduction

Four groups qualify:³

Sole proprietors and farmers with a net profit on Schedule C or Schedule F.
Partners with net earnings from self-employment reported on Schedule K-1.
Shareholders who own more than 2% of an S corporation that paid or reimbursed the premiums and reported those amounts as W-2 wages.⁴
Filers using one of the optional methods on Schedule SE.

The plan itself has to be established under your business. Sole proprietors have flexibility here: the policy can be in the business name or the owner’s personal name. Partners and more-than-2% S corporation shareholders have a tighter path. If the policy is in your personal name and you pay the premiums yourself, the partnership or S corporation has to reimburse you and include the reimbursement in your taxable income, as guaranteed payments for a partner or as W-2 wages for a shareholder. Without that reimbursement step, the IRS treats the plan as personal rather than business-established, and the deduction disappears.³

What Premiums Count

Line 17 covers premiums for medical, dental, and vision insurance for you, your spouse, your dependents, and any child who was under age 27 at year-end, even if that child is not your dependent.⁴ Medicare premiums you voluntarily pay are included.³

Qualified long-term care premiums are also deductible, but subject to age-based per-person caps. For 2025:

Age 40 or younger: $480
Age 41 to 50: $900
Age 51 to 60: $1,800
Age 61 to 70: $4,810
Age 71 or older: $6,020

These figures adjust annually for inflation. The 2026 numbers were not published as of this writing.⁵ When long-term care premiums are in the mix, the age cap applies to each covered person individually on Form 7206.

The Two Limits That Cut the Deduction

The first limit is the net profit cap. Your Line 17 deduction cannot exceed the earned income of the business under which the plan is established. A Schedule C showing $12,000 in net profit caps the deduction at $12,000 even if you paid $18,000 in premiums.⁴ For a more-than-2% S corporation shareholder, earned income means the W-2 wages that S corporation paid you. If you run more than one business with separate plans, you complete a separate Form 7206 for each and match each plan against the profits of the specific business that established it.³

The second limit is monthly and catches more people than the profit cap. You cannot deduct premiums for any month in which you were eligible to participate in a subsidized health plan offered by your own employer, your spouse’s employer, or the employer of a dependent or qualifying child. Eligibility alone disqualifies the month, whether or not you actually enrolled.³ Someone who worked a W-2 job with benefits January through June and freelanced full-time from July onward can only deduct premiums paid for July through December.

One thing this deduction does not do: it does not reduce self-employment tax. Line 17 only lowers your income tax. The self-employment tax side is handled separately by Line 15, the deductible portion of self-employment tax from Schedule SE.

How to Calculate and File It

Form 7206 is the worksheet. It is required if you had more than one source of self-employment income, if you file Form 2555, or if long-term care premiums are part of your deduction, and it is the standard calculation even when none of those apply.¹

The mechanics come down to comparing two numbers: total qualifying premiums paid during the year, and the net profit of the business under which the plan is established. Whichever is smaller goes on Line 17.¹

Marketplace coverage adds a wrinkle. If you bought your policy through the Health Insurance Marketplace and received advance payments of the premium tax credit, the deduction and the credit interact circularly: the deduction lowers your income, which changes the credit, which changes the deduction. The IRS directs you to Publication 974 for the iterative worksheet that resolves it.³

What Line 17 Does for Your Return

Part II of Schedule 1 collects individual adjustments on Lines 11 through 25. They total on Line 26 and carry to Form 1040, Line 10, where they reduce total income to produce adjusted gross income.²⁶ These are above-the-line adjustments, so they apply whether you take the standard deduction or itemize on Schedule A. For a self-employed filer paying $10,000 a year in premiums, a full Line 17 deduction lowers taxable income by that full amount, worth roughly $1,200 to $3,700 in federal income tax depending on the marginal bracket.

Penalties for Getting It Wrong

An overstated Line 17 deduction is treated like any other misreported adjustment. If the IRS corrects the return, you owe the additional tax plus interest. The underpayment interest rate is 6% for the second quarter of 2026.⁷

An accuracy-related penalty of 20% applies if the understatement of tax is large enough, defined for individuals as the greater of 10% of the correct tax or $5,000.⁸ The two most common ways people trip on Line 17 are deducting premiums for months when an employer plan was available, and exceeding the net profit cap. Keep premium invoices and proof of payment, and check that the Form 7206 numbers reconcile to the Schedule C, Schedule F, or K-1 income they depend on.
