Understanding Ohio's Income Tax
Ohio operates with a graduated income tax system, meaning tax rates increase as income rises. This system is designed to be progressive, with higher earners contributing a larger percentage of their income in taxes. The state also levies a state-wide tax in addition to local income taxes which vary by municipality. This calculator focuses solely on the state income tax calculation.

How the Calculator Works
This calculator applies Ohio's state income tax rates based on your provided taxable income and filing status. It determines which tax bracket your income falls into and calculates the tax owed for each portion of your income that falls within a specific bracket. The sum of these amounts represents your estimated Ohio state income tax liability.
Important Note: This calculator provides an estimate for Ohio state income tax only. It does not account for federal income tax, local income taxes (which vary significantly by city and locality within Ohio), or any tax credits or deductions you may be eligible for. For precise tax figures, consult a qualified tax professional or refer to official IRS and Ohio Department of Taxation publications.
