Ohio tax provisions for the treatment year
Ohio tax rules may reduce state taxable income for qualifying unreimbursed medical expenses.
What it is
Ohio tax rules may reduce state taxable income for qualifying unreimbursed medical expenses.
Medical and care costs count differently on the Ohio return than on the federal one. A preparer checks which costs qualify and whether they change what you owe. Ohio's disability-benefit deduction is for disability income received, not a credit for having a disabled child.
Eligibility rules
- Ohio’s medical deduction has separate rules for medical-care expenses and certain qualifying insurance premiums.
- Ohio separates qualifying medical expenses above 7.5% of federal adjusted gross income from certain qualifying health-insurance and long-term-care premiums. The rules cover eligible costs for the taxpayer, spouse and dependents, exclude reimbursements and amounts already deducted from adjusted gross income, and restrict the unsubsidized-premium deduction when employer-subsidized coverage or Medicare Part A is available. A preparer must check the individual expense and coverage rules.
What you get
- A possible reduction in Ohio taxable income for qualifying unreimbursed medical costs.
What this covers
- The tax saving depends on qualifying expenses, the return and the amount of state tax otherwise owed.
- A preparer can check Ohio’s nonrefundable earned income credit and child-and-dependent-care credit, as well as qualifying medical and insurance deductions. A separate provision can help a qualifying living organ or bone-marrow donor; it is not a general transplant-family deduction. The rules and the amount of tax otherwise owed determine the saving.
- For tax year 2025, Ohio’s earned income credit is 30% of the federal credit and is nonrefundable. The child-and-dependent-care credit is 100% of the calculated federal credit below $20,000 Ohio modified adjusted gross income, or 25% from $20,000 to below $40,000. It is nonrefundable and unavailable at $40,000 or more.
- A qualifying living organ or bone-marrow donor may deduct up to $10,000 once for eligible unreimbursed donation-related travel, lodging and lost wages. Being the transplant recipient does not itself qualify. A preparer checks the applicable-year rules before claiming savings-contribution provisions.
If you decide to apply
- You can ask a tax preparer or free tax-assistance site to review the treatment year's Ohio return.
- Useful records include medical and care receipts, reimbursement records and the prior return.

After you apply
- The preparer can show which provision appears on the return and how it changes the calculation.
Good to know
Expenses reimbursed by insurance or another source are different from costs your family pays. A deduction does not repay the bill dollar for dollar.
Other details
- Ohio disability-benefit income deductions concern qualifying benefit income, not a general disabled-child tax credit.
- For the 2025 return, the medical deduction is on Ohio Schedule of Adjustments line 44. A preparer can check a timely amended return for missed expenses and the refund-claim deadline. The correct form and line depend on the treatment year.
- The 2025 return’s ordinary deadline was April 15, 2026. A valid filing extension generally runs to October 15, 2026 and does not extend payment time. Ohio’s general refund-claim window is four years from payment, subject to the taxpayer’s circumstances.
