Short answer: if you own more than 2% of an S corporation in Ohio, the company pays or reimburses your health insurance premiums and puts them in Box 1 of your W-2 as wages, but not in the Social Security and Medicare boxes. You then take them back off your income as the self-employed health insurance deduction, on Form 7206 and Schedule 1, line 17. Ohio counts an owner’s pay from their own S corporation as business income and deducts the first $250,000 of it, so for most owner-run companies the saving is mainly federal.

How the Money Moves in Ohio
- Buy the planAny of the 9 insurers on the Ohio marketplace, or a private plan, in your name or the company’s.
- The S corp pays$606 a month for a 40-year-old’s cheapest 2027 Silver plan in Columbus, paid or reimbursed by the company.
- Payroll adds it$7,271 a year goes into W-2 Box 1 wages, not Boxes 3 and 5.
- Form 7206The deduction is worked out there, capped at your Medicare wages.
- Schedule 1Line 17: the $7,271 comes back off your income.
A more-than-2% shareholder is treated like a partner for fringe benefits, so the premiums cannot be a tax-free benefit the way they are for staff. IRS Notice 2008-1 is the route around that: wages for income tax, left out of Social Security and Medicare wages, then deducted under section 162(l).
Paying the premiums from your personal account and never running them through the company. The IRS’s own example in Notice 2008-1 is a shareholder who pays for a policy in their own name with no reimbursement: no plan established by the S corporation, no deduction.
In Columbus that mistake costs the whole $7,271 and roughly $1,745 of federal income tax at 24%. The fix has a deadline: the company pays or reimburses the premiums by December 31 and adds them to your W-2. The year-end checklist has every date in order.
Work out your deduction
Form 7206-style worksheet. An estimate, not a tax return.Presets: the typical lowest-cost Ohio Silver plan for 2027. Line 10: Social Security tax to the $192,300 wage base, Medicare 2.9%, plus 0.9% over $200,000. Nothing you type leaves this page until you send it.
The Cap Most Owners Miss
The deduction cannot be more than your earned income from the S corporation, which for a more-than-2% shareholder means wages as defined for Social Security and Medicare tax (section 162(l)(5)), Box 5 of the W-2. The premiums are in Box 1 but not Box 5, so they never raise the cap, and an owner who takes no salary gets no deduction at all. For the Columbus plan above, a salary of $7,271 or more keeps every dollar deductible.
Three More Rules
- The spouse ruleNo deduction for any month you could join a subsidized employer plan, yours or your spouse’s, even if you did not enroll.
- Family countsYour spouse, dependents and any child under 27 at year end are covered; an Ohio family of four’s typical lowest-cost Silver plan is $1,950 a month, $23,398 a year to deduct. A spouse, child, grandchild or parent of the owner counts as a 2% shareholder too.
- Marketplace creditOnly the premium you pay after any premium tax credit is deductible. Above $63,840 of income for one person there is no 2027 credit, so the full premium counts.
What It Is Worth in Ohio for 2027
| Household | Per month | Deductible per year | Federal tax saved at 22% | At 24% |
|---|---|---|---|---|
| One adult, 40 | $610 | $7,318 | $1,610 | $1,756 |
| Two adults, 40, and two children | $1,950 | $23,398 | $5,148 | $5,615 |
Ohio starts from federal adjusted gross income. For 2026 it taxes nonbusiness income above $26,050 at a flat 2.75% (H.B. 96), deducts the first $250,000 of business income and taxes business income above that at 3%. The marketplace in Ohio has 9 insurers for 2027, a median of 78 plan options per county, and no PPO in any of its 88 counties: every plan is an HMO. Above $63,840 of household income for one person ($132,000 for a family of four) there is no premium tax credit, so the deduction carries the full saving.

Ohio’s Business Income Deduction
Ohio counts compensation a pass-through entity pays to an owner of 20% or more as business income, along with the company’s profit. The first $250,000 of business income is deducted ($125,000 married filing separately), and business income above that is taxed at a flat 3%. Nonbusiness income, such as a spouse’s wages or interest, is taxed at 2.75% above $26,050 for 2026.
Ohio also has its own deduction for health insurance premiums paid for months you were not eligible for an employer plan or Medicare (unreimbursed medical care expenses, Ohio Schedule of Adjustments). It starts from your premiums less the federal self-employed health insurance deduction, so premiums the federal deduction could not absorb can still count in Ohio.

Common Questions
Can an S corp owner deduct health insurance in Ohio?
Yes, if you own more than 2% and the S corporation pays or reimburses the premiums and reports them in Box 1 of your W-2. You deduct them on Form 7206 and Schedule 1, line 17. Ohio counts an owner’s pay from their own S corporation as business income and deducts the first $250,000 of it, so for most owner-run companies the saving is mainly federal.
What if I paid the premiums from my personal account?
Have the S corporation reimburse you and add the amount to your W-2 before it is issued. A policy you pay yourself with no payment or reimbursement by the company gets no deduction; in Columbus that is $7,271 a year on the cheapest Silver plan for a 40-year-old.
Do Ohio S corp owners pay Ohio tax on their own wages?
Not on the first $250,000. Ohio counts compensation from a pass-through entity to an owner of 20% or more as business income, deducts the first $250,000 of business income and taxes the rest at a flat 3%.
