Self-employed health insurance deduction calculator
Your premiums cut two tax bills at once. See what the cover really costs.
When you are self-employed you buy your own health cover — and you get a deduction for it that employees cannot use.
This calculator works out the deduction you can actually claim, and splits the saving into the part that reduces your self-employment tax and the part that reduces your income tax.
The deduction employees never get to use
If you are employed, health insurance is a benefit your employer buys and you largely never see the price of. If you are self-employed, you buy the cover yourself — and Congress built a specific deduction to soften that. The self-employed health insurance deduction lets you deduct premiums you pay for medical, dental and qualifying long-term care insurance for yourself, your spouse and your dependents.
The detail that makes it unusual: it is an above-the-line deduction, also called an adjustment to income. You claim it whether or not you itemise. An employee who pays medical bills out of pocket must clear the 7.5%-of-AGI floor and itemise to get any relief at all; a self-employed person deducts the premiums straight off the top. That structural difference is worth real money.
Why the saving is bigger than your tax bracket suggests
Most people estimate the value of a deduction by multiplying it by their marginal rate. This one is worth more, because it reduces two separate tax bases at once.
- Self-employment tax. The deduction lowers your net earnings from self-employment, and net earnings are what the 15.3% Social Security and Medicare tax is charged on. That is a direct 15.3% saving on the deductible amount, before any income tax enters the picture.
- Income tax. The same amount is then deducted again as an adjustment to income, saving your marginal federal and state rate on top.
Stack them and a deduction in the low five figures can be worth a third or more of the premium bill. That is why the calculator reports the two components separately — the combined figure is genuinely counter-intuitive the first time you see it.
Three limits that catch people out
The deduction is generous but not unlimited, and the restrictions are where most mistakes happen.
1. It cannot exceed your net profit. The deduction is capped at the net profit your business earned for the year, after all other business expenses but before this deduction. A slow year with $4,000 of profit and $14,000 of premiums yields a $4,000 deduction, not $14,000. The calculator applies this cap and tells you how much was left over.
2. You cannot claim it for months you could have had employer cover. If you were eligible to participate in a subsidised health plan maintained by your spouse's employer (or your own, from a separate W-2 job) for any month of the year, the deduction is disallowed for that month — even if you turned the cover down and bought your own policy instead. This catches a lot of people whose spouse has a family plan available but declined to add them because their own policy was cheaper.
3. You cannot double up with the premium tax credit. If you buy Marketplace cover and receive the advance premium tax credit, the two benefits interact. You cannot deduct the full premium and also keep the full credit; the reconciliation is done on the self-employed health insurance worksheet in the instructions, and the net figure is what you deduct. If you are in this position, treat the calculator's output as an upper bound rather than a final answer.
Who counts as covered
The policy can cover you, your spouse and your dependents, and it does not have to be issued in the business's name — a policy in your own name qualifies as long as you are the one paying the premiums and you have net profit from the business. A child under 27 at the end of the year can qualify even if they are not your dependent for tax purposes.
Two structures need their own handling. S-corp shareholders who own more than 2% should have the corporation pay the premiums and include them in W-2 wages; the deduction is then taken by the shareholder personally. Partnerships treat partner premiums similarly, with the partnership paying and the partner deducting. In both cases the mechanics differ from a sole proprietor even though the end result is close.
What to do with the number
Use it in two places. First, in pricing: if your health cover effectively costs you 30% less than the sticker price because of this deduction, that belongs in the overhead line of your rate calculation rather than being silently absorbed. Second, in cash flow: the deduction reduces your quarterly estimated payments, so it should feed into how much you set aside each quarter rather than being discovered at filing time.
And keep the paperwork. The deduction is claimed on your individual return, so you need a clean record of what you actually paid — insurer statements, not a guess at the monthly amount — plus evidence of your net profit for the year.
Estimates only. This calculator applies the general federal rules: the net-profit cap, the 15.3% SE tax reduction and your stated marginal rate. It does not model the premium tax credit reconciliation, state-level differences, S-corp and partnership mechanics, or long-term-care age-based limits. Confirm your own position against current IRS guidance (Publications 334 and 535) and, for anything beyond straightforward sole-proprietor cover, a tax professional — see the disclaimer.
Frequently asked questions
Can self-employed people deduct health insurance premiums?
Yes, through the self-employed health insurance deduction. You can deduct premiums you pay for medical, dental and qualifying long-term care insurance covering you, your spouse and your dependents. It is an above-the-line deduction, so you claim it even if you do not itemise, and you generally need net profit from the business to claim it.
Do I have to itemise to claim this deduction?
No. It is an adjustment to income, sometimes called an above-the-line deduction, which means you subtract it from gross income before arriving at adjusted gross income. You get the benefit whether you take the standard deduction or itemise. That is a major advantage over the itemised medical-expense deduction, which is limited to the amount exceeding 7.5% of AGI.
What happens if my premiums exceed my business profit?
The deduction is capped at your net profit from the business for the year, so the excess cannot be deducted this year. The cap is calculated after all other business expenses but before the health insurance deduction itself. If premiums exceed profit, check whether the Marketplace premium tax credit applies to your coverage instead.
Can I claim it if my spouse has a health plan at work?
Generally not for any month in which you were eligible to participate in that subsidised employer plan, even if you declined the cover and bought your own policy because it was cheaper. Eligibility, not enrolment, is the test. If you genuinely had no access to a subsidised employer plan for the whole year, you can claim the full year.
Does the deduction also reduce my self-employment tax?
Yes. The deduction lowers your net earnings from self-employment, and net earnings are the base for the 15.3% Social Security and Medicare tax. So the same premium amount saves you SE tax first and income tax second, which is why the total saving is noticeably larger than your marginal rate alone would suggest.
Does the policy have to be in my business name?
No. A policy in your personal name qualifies as long as you pay the premiums and you have net profit from the business you are deducting against. S-corp shareholders owning more than 2% are the exception: the corporation should pay the premiums and include them in W-2 wages, with the shareholder then taking the deduction personally.
