Ohio Tax Brackets 2025 Guide – If you live or work in Ohio, understanding the 2025 state income tax brackets is essential for accurate filing and maximizing your refund. The Buckeye State’s tax system remains one of the most straightforward in the nation, with just three brackets for nonbusiness income and a top rate that dropped again in 2025. This comprehensive guide breaks down everything Ohio taxpayers need to know for tax year 2025 (returns filed in 2026), including official brackets, personal exemptions, key deductions, school district taxes, and step-by-step filing advice.
2025 Ohio Income Tax Brackets and Rates
Ohio uses a progressive tax structure only on taxable nonbusiness income. The brackets and rates for taxable years beginning in 2025 are:
| Ohio Taxable Income | Tax Calculation |
|---|---|
| $0 – $26,050 | 0.000% |
| $26,050 – $100,000 | $342.00 + 2.75% of excess over $26,050 |
| Over $100,000 | $2,394.32 + 3.125% of excess over $100,000 |
Important notes:
- These rates apply to all filing statuses (single, married filing jointly, head of household, etc.).
- Taxable business income (from pass-through entities, sole proprietorships, etc.) continues to be taxed at a flat 3% after a deduction of up to $250,000 ($125,000 if married filing separately).
- The top marginal rate fell from 3.5% in 2024 to 3.125% in 2025 as part of ongoing tax relief.
How Ohio Tax Brackets Work: Quick Examples?
Ohio taxes income marginally—just like the federal system. You only pay the higher rate on the portion of income that falls into each bracket.
Example 1: Single filer with $50,000 taxable nonbusiness income
- $0–$26,050 → 0% = $0
- $26,051–$50,000 ($23,950) → 2.75% = $658.63
Total state tax: $658.63
Example 2: Married filing jointly with $150,000 taxable nonbusiness income
- $0–$26,050 → 0% = $0
- $26,051–$100,000 ($73,950) → 2.75% = $2,033.63
- Over $100,000 ($50,000) → 3.125% = $1,562.50
Total state tax: $3,596.13 (before credits)

2025 Ohio Personal Exemptions
Ohio offers a per-person exemption that reduces your taxable income. The amount depends on your modified adjusted gross income (MAGI):
| Modified AGI | Exemption Amount per Person |
|---|---|
| $40,000 or less | $2,400 |
| $40,001 – $80,000 | $2,150 |
| $80,001 – $749,999 | $1,900 |
| $750,000 or greater | $0 |
Exemptions apply to you, your spouse (if filing jointly), and each dependent claimed on your federal return. Multiply the appropriate amount by the number of exemptions and subtract on your Ohio IT 1040.
