Ohio Income Tax Calculator 2026 – how it works
Ohio state income tax on taxable nonbusiness income is based on marginal brackets defined by income thresholds and rates. Income from 0 to 26,050 is subject to a 0.00% rate. Income above 26,050 and up to 100,000 is subject to a 2.75% rate, and income above 100,000 is subject to a 3.50% rate. This calculator uses the published bracket thresholds and marginal rates for taxable nonbusiness income, while the official Ohio calculation also incorporates base tax amounts. Official rate information is published by the Ohio Department of Taxation.
Examples
Example 1: If Ohio taxable nonbusiness income is within the first bracket, income up to 26,050 is subject to a 0.00% rate. Example 2: If Ohio taxable nonbusiness income exceeds 26,050 but does not exceed 100,000, the portion above 26,050 is subject to a 2.75% rate. Example 3: If Ohio taxable nonbusiness income exceeds 100,000, the portion above 100,000 is subject to a 3.50% rate.
Limitations and important notes
Results are simplified estimates and may not match a filed return. Ohio’s official income tax calculation uses base tax amounts in combination with marginal rates for taxable nonbusiness income. This calculator reflects the published bracket thresholds and marginal rates as currently published but does not account for all return-specific factors, income classifications, credits, or deductions. Final tax liability depends on how income is defined and reported under Ohio law.
