The Self-Employed Health Insurance Deduction: 100% Deductible and Almost Nobody Claims It

If you pay for your own health insurance as a self-employed worker, you can deduct 100% of those premiums directly from your adjusted gross income. Not as an itemized deduction. Not subject to the 7.5% AGI floor that applies to medical expenses. Right off the top.

A freelancer paying $600 per month for health insurance can deduct $7,200 per year. At a combined income tax and SE tax rate around 36%, that is $2,592 in tax savings from something they were already paying for.

Most people do not claim it. They either do not know it exists or assume they do not qualify.

Who Qualifies

You qualify for the self-employed health insurance deduction if:

• You had net profit from self-employment during the year
• You were not eligible for coverage through an employer-sponsored plan (your own employer or a spouse's employer)
• You paid the premiums yourself

That second condition is the one that disqualifies people. If your spouse has an employer health plan that covers you, and you could have enrolled but chose not to, you cannot take this deduction. Eligibility for coverage disqualifies you, not actual enrollment.

Month-by-month calculation: The IRS applies this eligibility rule month by month. If you had W-2 employment with health coverage from January through June and went freelance in July, you can deduct premiums for July through December but not for January through June.

What Counts as a Deductible Premium

Covered:

• Medical, dental, and vision premiums for yourself
• Premiums covering your spouse and dependents
• Long-term care insurance premiums (subject to age-based limits)
• Medicare Part B and Part D premiums (if you are 65 or older and self-employed)
• Marketplace health plan premiums
• Direct-pay premiums outside the Marketplace

Not covered:

• Premiums paid with pre-tax HSA funds
• Premiums reimbursed by any employer plan
• Life insurance premiums
• Workers' compensation

The Deduction Is Limited to Your Net SE Income

The deduction cannot exceed your net self-employment income. If you had $5,000 in health insurance premiums but only $3,000 in net SE income for the year, you deduct $3,000, not $5,000.

This matters for part-year freelancers and low-income years. If the business lost money or broke even, there is no deduction because there is no qualifying income to deduct against.

Where This Deduction Lives

The self-employed health insurance deduction goes on Schedule 1, Line 17, not on Schedule C. This is an above-the-line deduction that reduces your adjusted gross income.

Reducing AGI matters beyond the direct tax savings because AGI determines eligibility for dozens of other deductions and credits. Lower AGI can also affect whether you qualify for the premium tax credit on Marketplace coverage.

The ACA Premium Tax Credit Interaction

If you purchased coverage through the ACA Marketplace and received premium tax credits (subsidies), the interaction with the self-employed deduction gets slightly complex.

You cannot double-dip. The deduction applies to the net premium you actually paid, after subtracting advance premium tax credits. If the Marketplace covered $400/month and you paid $200/month, you deduct $200/month.

For lower-income freelancers, the premium tax credit may be more valuable than the deduction. The calculation depends on your specific income level and the available credits. Tax software handles this automatically, but understanding the interaction helps you make enrollment decisions.

S-Corp Owners: A Slightly Different Process

S-corp owners who take a W-2 salary from their corporation must have the corporation pay the health insurance premiums (or reimburse you) and include the premium amount in your W-2 wages in Box 1. Then you claim the deduction on Schedule 1.

This is purely administrative (the economic effect is the same), but if the premium is not properly run through payroll, the deduction may be challenged. If you have an S-corp, confirm with your bookkeeper that health insurance is flowing through payroll correctly.

Long-Term Care Insurance

The deduction also covers long-term care insurance premiums, but with age-based limits set by the IRS annually. For 2025: $480 if you are 40 or under, $900 for ages 41-50, $1,800 for 51-60, $4,800 for 61-70, and $6,020 for 71 and older. These are the maximum deductible amounts regardless of actual premiums paid.

The Number to Know

For most self-employed workers paying market rates for individual or family health coverage, this deduction is worth $1,500 to $4,000 in actual tax savings per year. It requires one line on your tax return. If you have been paying premiums without claiming it, you can amend prior year returns going back three years.
