Self-Employed Health Insurance Deduction Calculator

Last updated: August 12, 2026 · Figures for tax year 2026

If you are self-employed and pay your own health insurance, the premiums are an above-the-line deduction — they lower your income tax without itemizing. This calculator shows your deductible amount and the tax saved, with the self-employment tax caveat built into the note.

How to use this calculator

  1. Enter annual health insurance premiums.
  2. Enter net self-employment profit.
  3. Enter filing status.
  4. Your results appear instantly below and update as you change the numbers.

How this calculator works

The deduction equals your premiums but cannot exceed your net self-employment profit. It reduces income tax at your marginal rate, but — unlike most business deductions — it does not reduce self-employment tax: you still owe 15.3% on the money you used to pay premiums. Worked example: $12,000 of premiums against $80,000 of profit at a 22% marginal rate deducts the full $12,000 and saves $2,640 on income tax — but you still pay roughly $1,836 of self-employment tax on that same $12,000, which is why the deduction is worth less than it first looks.

Frequently asked questions

Does this work if I also have a W-2 job with insurance?

No — the deduction is only for health insurance you pay yourself when self-employed, and it is unavailable for any month you (or your spouse) were eligible for an employer-subsidized plan.

Can I deduct premiums for my family too?

Yes — premiums for your spouse and dependents are included in the same deduction, still limited to your net self-employment profit.

Why is it better than a regular business expense?

It is an above-the-line deduction, so it lowers your adjusted gross income without itemizing — and a lower AGI can preserve other deductions and credits that phase out at higher incomes.
