Ohio Income Tax: Graduated Brackets Up to 3.5%
Ohio uses a progressive income tax system with 3 brackets. Rates range from 0% to 3.5%, with higher income taxed at higher rates. Ohio exempts the first $26,050 of income from tax. Many cities levy additional municipal income taxes.
Like federal taxes, Ohio's system is marginal — only the income within each bracket is taxed at that bracket's rate. Combined with federal taxes (10%–37%), Ohio residents can face a total marginal rate of up to 40.5% on their highest dollars of income.
Ohio Tax Brackets for 2026 (Single Filer)
The Ohio income tax brackets for single filers are:
- 0% on income from $0 to $26,050
- 2.75% on income from $26,050 to $100,000
- 3.5% on income over $100,000
Your marginal rate is the rate on your last dollar of income. Your effective rate (total tax divided by total income) is always lower because of the progressive structure.
Tips to Lower Your Ohio Tax
Maximize pre-tax retirement contributions to reduce both federal and Ohio taxable income. The 2026 401(k) limit is $24,500 ($32,500 with catch-up for age 50+). If Ohio conforms to federal deductions, your standard deduction and itemized expenses also reduce your state tax liability.
