Self-Employed Health Insurance Deduction Calculator
Self-employed individuals, including sole proprietors, partners, S corporation shareholders who own more than 2%, and single-member LLC owners, can deduct 100% of the premiums they pay for health, dental, and qualifying long-term care insurance for themselves, their spouses, their dependents, and any children under age 27 as an above-the-line deduction under IRC Section 162(l). This deduction reduces adjusted gross income without requiring itemisation and is claimed on Schedule 1 of Form 1040. The deduction is limited to the net profit from self-employment: if your business had a loss or your net profit is less than the total premiums paid, you cannot deduct more than your net earnings. If you are eligible to participate in any subsidised health plan through an employer (including your own S corporation as an employee) or through a spouse's employer for any month during the year, you cannot claim the self-employed health insurance deduction for premiums covering that month. Premiums paid through a health reimbursement arrangement or any other tax-free arrangement also do not qualify.
With gross self-employment income of $90,000, business expenses of $20,000, and health insurance premiums of $8,400, your allowable deduction is --, saving you -- in federal and state taxes.
How the self-employed health insurance deduction is calculated
The self-employed health insurance deduction is an above-the-line adjustment to gross income, reducing your adjusted gross income (AGI) on Schedule 1 of Form 1040. It is subject to two limitations: it cannot exceed your net self-employment income after the self-employment tax deduction, and it cannot exceed the premiums you actually paid.
net SE income = gross revenue - business expenses
SE tax = net SE income x 0.9235 x 0.153
half SE tax = SE tax / 2
income limit = net SE income - half SE tax
deduction = min(premiums paid, income limit)
federal savings = deduction x (federal rate / 100)
state savings = deduction x (state rate / 100)
effective premium cost = premiums - (federal + state savings)
Worked example
Gross $90,000, expenses $20,000, premiums $8,400, federal rate 22%, state rate 5%:
- Net SE income = 90,000 - 20,000 = $70,000
- SE tax = 70,000 x 0.9235 x 0.153 = $9,858.26
- Half SE tax = 9,858.26 / 2 = $4,929.13
- Income limit = 70,000 - 4,929.13 = $65,070.87
- Deduction = min(8,400, 65,070.87) = $8,400 (premiums are lower)
- Federal savings = 8,400 x 0.22 = $1,848.00
- State savings = 8,400 x 0.05 = $420.00
- Effective cost = 8,400 - 1,848 - 420 = $6,132.00
Key rules and limitations
The self-employed health insurance deduction is only available to self-employed individuals who have net self-employment income and cannot claim employer-subsidized coverage. You must have a business that generated the income in the year of the deduction, and you cannot have received coverage through an employer plan at any point in that year (for yourself or your spouse).
If you have a business loss or net income is zero, no deduction is available. Similarly, in months when you were eligible for subsidized health insurance through your employer or your spouse's employer, you cannot deduct premiums for that month. If your eligibility was partial (for example, you started self-employment mid-year), you can deduct premiums only for the months you were not eligible.
The deduction cannot exceed the actual premiums you paid. It is an above-the-line deduction, which means it reduces your AGI before you claim either the standard deduction or itemized deductions. This makes it particularly valuable for high-income self-employed individuals who lose itemization benefits at high incomes, as the reduction in AGI can also reduce exposure to net investment income tax, alternative minimum tax, and certain phase-outs on credits and deductions.
Self-employed health insurance deduction: frequently asked questions
What counts as self-employed health insurance for the deduction?
The deduction covers medical, dental, vision and qualified long-term care insurance premiums paid for yourself, your spouse and your dependents. It does not include premiums paid through a cafeteria plan (like an FSA) or with pre-tax dollars through an employer plan. The coverage must be under your self-employment business's name or cost to qualify.
Why is the deduction limited by net profit?
IRC Section 162(l) limits the health insurance deduction to your net self-employment income minus half of your self-employment tax. This prevents you from deducting more than your business actually earned. A loss in any month means no deduction for that month, and in net-loss years, no deduction is available.
What is the employer subsidy rule?
You cannot claim the deduction for any month in which you or your spouse were eligible for subsidized health insurance through an employer plan. Even if you did not actually enroll, eligibility disqualifies you. This applies to both your employer and your spouse's employer. If you were only eligible for part of the year, you can claim the deduction for the months you were not eligible.
Is the deduction above-the-line and what does that mean?
Yes. An above-the-line deduction reduces your adjusted gross income (AGI) on Schedule 1 of Form 1040 before you report either standard or itemized deductions. Reducing AGI can also lower your tax on other income-sensitive items like net investment income tax, NIIT, and certain credits. This makes the self-employed health insurance deduction more valuable than a below-the-line business expense.
How do I report this deduction on my tax return?
Report the deductible amount on Schedule 1, Form 1040, line 21 (self-employed health insurance deduction). You must also file Schedule C or Schedule F showing your self-employment income and expenses. The IRS Publication 535 and Form 1040 instructions contain the detailed rules and box-by-box guidance.
Can I deduct long-term care premiums?
Yes, qualified long-term care insurance premiums are deductible subject to age-based limits. For 2025, the limit is $530 for age 40 and under, increasing to $3,175 for age 70 and older. However, the total cannot exceed your net self-employment income for the year. The IRS Publication 535 contains the full limits by age.
