An S-corp owner has the most control over this of any entity type, and the most ways to get it wrong. The premium has to travel a specific route — through payroll, onto the W-2, then off the personal return — and if any step is skipped the deduction is lost.
If you own more than 2% of an S-corp, the corporation can pay your health insurance premium, but it must include that amount in your W-2 wages. You then deduct it on your personal return as self-employed health insurance. The money is not subject to Social Security and Medicare tax, and the net effect is a deduction against income tax — but only if the W-2 step actually happened. A premium the company paid and never reported is the single most common mistake I see on an S-corp return.
Your W-2 salary has to be reasonable for the work you do — that is not negotiable and the IRS looks at it. Within what is reasonable, though, the split between salary and distributions moves your income, and your income decides your premium tax credit. Retirement contributions move it again.
There is a wrinkle worth knowing: the health insurance deduction itself reduces the income your credit is measured against, so the deduction and the credit are circular and have to be solved together. Working them out in sequence gives the wrong answer.
That depends entirely on where you are. In Arkansas crossing $62,600 costs a 40-year-old $3,053 a year; in Maryland, Virginia, Indiana, Nevada and Ohio it costs nothing at all at that age, because the benchmark plan is already cheaper than the subsidy cap. The state-by-state figures are here.
Yes, and for a more-than-2% shareholder it must then be included in your W-2 wages. You deduct it on your personal return afterwards. If it never appears on the W-2, the deduction is not available.
Yes, if your household income is under 400% of the federal poverty level — $62,600 for a single filer in 2026 — and you are not eligible for affordable employer coverage elsewhere. Your own S-corp coverage counts as self-employed coverage, not as an employer offer to yourself.
It depends on whether you have other employees and what they earn. With no employees, a marketplace plan is almost always simpler and often cheaper after credits. With staff, it is worth pricing a small group plan and a reimbursement arrangement against each other before you decide.
Benchmark premiums: the second-lowest-cost Silver plan for a 40-year-old, weighted by county enrollment, from the CMS PY2026 Landscape file, the same figures used across this site. Cliff: 400% of the 2025 HHS poverty guideline (90 FR 5917), $62,600 for a single-adult household. Applicable percentage: 9.96% for 2026 (Rev. Proc. 2025-25). Nothing here is tax advice — the arithmetic is public, the decision is yours and your CPA’s.
