Marriage Tax Calculator for Ohio

Ohio's flat 2.75% state income tax interacts with federal brackets to create marriage bonuses or penalties that differ from the federal-only effect. Since Ohio uses a flat rate, the state tax does not create its own marriage penalty, but it does amplify the federal effect by adding to the total tax burden. Local income taxes in Ohio add yet another variable to the marriage tax equation. This calculator shows the combined federal and Ohio state marriage tax impact.

Ohio levies a flat 2.75% state income tax on all taxable income regardless of how much you earn. This makes tax planning straightforward: for every additional dollar you earn, 2.75 cents goes to Ohio. However, certain localities in Ohio impose their own income taxes, which effectively raise the combined state and local rate above 2.75%. Be sure to check whether your city or county adds a local income tax.
