Ohio Paycheck Calculator

An Ohio paycheck can carry federal income tax, state withholding, city income tax for the city where you work, and in some districts a school district tax. The calculator above handles the first three. Pick a city preset or type your own rate, and the city tax appears with the state line instead of being folded into one number.

The August 1, 2026 change to Ohio withholding

Ohio published new withholding tables that apply to wages paid on or after August 1, 2026. The calculator uses them. The Department of Taxation’s formula starts with your annual wages and subtracts $650 for each exemption on your IT 4. The remainder is taxed at 1.6% up to $26,050, then 2.99% up to $100,000, then 3.4% above that.

The tables in force from October 1, 2025 through July 31, 2026 had rates of 1.775%, 2.99% and 3.64%. If you are comparing a paycheck from the spring with one from the fall, that is the reason state tax moved. Ohio uses exemptions rather than a filing status, so married and single filers are treated alike for state withholding and only the federal line changes.

Exemptions and the IT 4

Ohio’s employer withholding rules say a worker who does not turn in an IT 4 is withheld as if they claimed zero exemptions. That produces the highest state withholding for your pay level, so a missing form is the first thing to check if your state line looks high. The three examples below assume one exemption and no city tax, so they show a common case.

City income tax

Ohio cities tax wages, and your employer withholds that tax for the city where you work. Ten presets are built into the calculator. Columbus, Cleveland, Toledo, Akron, Dayton, Parma, Canton and Lorain are each 2.5%. Cincinnati is 1.8% and Hamilton is 2%. City pages or codes are the source for the first nine. Hamilton’s rate comes from the state’s local government table for 2024, because the city page we found did not state it.

If you live in one city and work in another, credit rules can change what you owe when you file. The calculator applies a single rate and does not model those credits.

School district income tax

Some Ohio school districts levy an income tax too. Depending on the district, it is based either on the same wages and exemptions the state uses or on earned income at a flat rate. Rates are in a school district list from the Department of Taxation. The calculator does not include school district tax, so if you live in one of those districts, subtract that amount from the estimate yourself.

Bonuses

The Department of Taxation’s employer withholding page gives 2.75% as the state rate on supplemental pay such as bonuses. We have not confirmed whether that rate changed on August 1, so check it against the current page if a large bonus is involved.

No state payroll deduction

We found no Ohio employee-paid payroll contribution, such as a state disability program, in the employer withholding materials. Ohio’s page does not state that outright, so treat it as what the sources checked do not show.
