Ohio's Zero-Bracket Explained
Unlike most states that use a standard deduction subtracted from income, Ohio achieves a similar effect through a zero-bracket: the first $32,200 of income faces a 0% rate. This means Ohioans earning under $32,200 pay zero state income tax. The flat 2.75% rate only begins on income above that threshold, making Ohio's effective rate always lower than 2.75%.
School District Income Tax
About 200 Ohio school districts levy an additional income tax on top of the state rate. Rates range from 0.5% to 2.5%. Columbus City School District charges 2.5%, while many suburban districts charge 1%โ1.5%. Check your district's rate with the Ohio Department of Taxation to ensure accurate calculations.
