Schedule 1 Line 17: Self-Employed Health Insurance Deduction Limits

Schedule 1, Line 17 is where a self-employed person deducts what they paid for health, dental, and vision insurance, and it directly reduces the income the IRS taxes. You calculate the amount on Form 7206, cap it at the net profit of the business that established the plan, and enter the result on Line 17 of Schedule 1. From there it flows into the Part II total on Line 26 and over to Form 1040, lowering your adjusted gross income.¹

Who Can Claim the Deduction

Four groups qualify:²

Sole proprietors and farmers with a net profit on Schedule C or Schedule F.
Partners with net earnings from self-employment on a Schedule K-1.
Shareholders who own more than 2% of an S corporation that paid or reimbursed their premiums and reported those amounts as W-2 wages.³
Filers who used one of the optional methods on Schedule SE to figure net earnings.

The plan has to be established under your business. Sole proprietors can hold the policy in their own name or the business name. Partners and S corporation shareholders face a stricter setup: 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 amount in your taxable income (as guaranteed payments for partners, or W-2 wages for shareholders). Skip that reimbursement step and the IRS treats the plan as personal, not business, and the deduction disappears.²

What Premiums You Can Include

The deduction covers medical, dental, and vision premiums for you, your spouse, your dependents, and any child who was under age 27 at year-end, whether or not that child is your dependent.³ Medicare premiums you voluntarily pay count too.²

Qualified long-term care insurance premiums are eligible, but only up to age-based caps. For 2025, the per-person limits are:⁴

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

The caps are inflation-adjusted each year. The 2026 figures had not been published at the time of writing. If long-term care premiums are part of your total, Form 7206 is required and you apply these caps to each covered person separately.

The Two Limits That Shrink the Deduction

The first is the net profit cap. Your Line 17 deduction cannot exceed the earned income from the business that established the plan. If Schedule C shows $12,000 in net profit and you paid $18,000 in premiums, your deduction stops at $12,000.³ For an S corporation shareholder, earned income means W-2 wages from that S corporation. Multiple businesses each with their own health plan? You need a separate Form 7206 for each, matching each plan’s premiums against the income of the business that established it.²

The second is the month-by-month employer plan rule, and it catches more people than the profit cap. You cannot take the deduction 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, even if you never enrolled.² Freelancing on the side of a W-2 job with benefits, or having a spouse whose job offers coverage, can wipe out months of premiums. If you were eligible for an employer plan January through June and self-employed the rest of the year, only July through December premiums count.

One boundary worth naming: Line 17 reduces income tax only. It does not reduce your self-employment tax. The deductible half of SE tax has its own spot on Line 15.

How to Calculate and Report It

Complete Form 7206 and attach it to your return. The form is required if you had more than one source of self-employment income, you file Form 2555, or you are including long-term care premiums. Even outside those cases, Form 7206 is the standard worksheet.¹

The core calculation compares two numbers: total qualifying premiums paid during the year, and the net profit (or W-2 wages, for an S corp shareholder) of the business that established the plan. The smaller number is what you write on Line 17 of Schedule 1.¹

Marketplace coverage with advance premium tax credits complicates things. Your Line 17 deduction lowers your income, which changes the premium tax credit you qualify for, which changes the deduction, which changes the income again. The IRS points you to Publication 974 for the iterative worksheet that resolves the loop.²

Once Line 17 is filled in, Schedule 1 totals all Part II adjustments on Line 26, and that number transfers to Form 1040, Line 10.⁵ The deduction is above-the-line, so you get it whether you itemize on Schedule A or take the standard deduction.

What Getting It Wrong Costs

Claiming Line 17 when you don’t qualify, or claiming too much, means the IRS bills you for the additional tax and interest. The underpayment interest rate for the second quarter of 2026 is 6%.⁶

A large enough understatement adds a 20% accuracy-related penalty on top of the tax. For individuals, “large enough” means your tax was understated by the greater of 10% of the correct tax or $5,000.⁷ The two failure patterns to watch are claiming premiums for months when an employer plan was available, and running past the net profit cap. Keep invoices and proof of payment for every premium, and make sure the numbers on Form 7206 tie back to your Schedule C, K-1, or W-2.
