Self-Employed Health Insurance Deduction: Complete Guide

Self-Employed Health Insurance Deduction: Complete Guide 2026

If you pay for your own health insurance as a self-employed individual, you can deduct 100% of your premiums — for yourself, your spouse, and your dependents. This above-the-line deduction reduces your adjusted gross income regardless of whether you itemize, making it one of the most valuable tax benefits available to the self-employed.

Who Qualifies

You qualify for this deduction if you are:

A sole proprietor or single-member LLC
A partner with self-employment income
An S corporation owner with at least 2% ownership and wages from the S corp
Any individual with net self-employment income

Key limitation: You cannot claim this deduction for any month in which you were eligible to participate in an employer-sponsored health insurance plan — including a plan through your spouse's employer.

What You Can Deduct

Eligible premiums include:

Medical insurance premiums
Dental insurance premiums
Vision insurance premiums
Long-term care insurance premiums (subject to age-based limits)

You can also include premiums paid for your spouse, dependents, and children under age 27 even if they are not your tax dependents.

The Income Limitation

The deduction cannot exceed your net self-employment income from the business under which the insurance plan is established. If your business had a loss, you cannot take this deduction.

Example: You earned $30,000 from self-employment and paid $18,000 in premiums. You can deduct the full $18,000. But if you earned only $10,000, your deduction is capped at $10,000.

How the S Corporation Rule Works

S corporation owners who receive a salary must follow specific steps:

The S corporation pays for the health insurance (or reimburses the owner)
The premium amount is added to the owner's W-2 wages in Box 1 (but not Boxes 3 and 4)
The owner then deducts the premium on Schedule 1 of Form 1040

If the premium is not reflected on the W-2, the deduction is disallowed. This is one of the most commonly missed steps in S corporation tax planning.

Where to Claim It

Sole proprietors and single-member LLCs: Deduct on Schedule 1 (Part II, Line 17) of Form 1040. Do not include on Schedule C — this deduction comes off your total self-employment income, not just one business.

Partners: The deduction flows through the partnership's reporting or is claimed on Schedule 1.

S corporation shareholders: Deduct on Schedule 1 after the amount is included in W-2 wages.

Long-Term Care Insurance

Long-term care insurance premiums are deductible up to the following limits based on age as of December 31 of the tax year:

Age 40 or younger: $480
Age 41-50: $890
Age 51-60: $1,790
Age 61-70: $4,770
Age 71+: $5,960

These amounts are for 2024; 2025 limits are typically adjusted for inflation.

Coordinating with ACA Marketplace Plans

If you purchased insurance through the ACA marketplace and received premium tax credits, you can only deduct the portion of premiums you actually paid out of pocket — not the amount covered by the credit. The deduction and credit cannot apply to the same premium dollar.

The Bottom Line

This deduction can save thousands of dollars annually. A self-employed individual paying $12,000 per year in premiums in the 22% tax bracket saves $2,640 in federal income tax — and also reduces the income subject to state taxes in most states.
