Yes, Ohio has a state income tax that applies to most residents and workers

Ohio charges a state income tax on wages, salaries, and other income earned by residents and people who work in the state. The tax rate ranges from 0.5% to 5.75% depending on your income level — Ohio uses a progressive system where higher earners pay a higher percentage. This is separate from federal income tax, which you also owe to the IRS.

If you work in Ohio but live in another state, you may owe Ohio income tax on wages earned within the state, though you can usually claim a credit on your home state's return to avoid double taxation. If you live in Ohio but work remotely for an out-of-state employer, you still owe Ohio tax on that income.

Key Takeaways

  • Ohio's state income tax ranges from 0.5% to 5.75% based on your income bracket, with higher earners paying the top rate.
  • You owe Ohio income tax if you are a resident of the state or if you earned income within Ohio, regardless of where you live.
  • Ohio taxes wages, salaries, interest, dividends, and business income, but not all types of income are taxed at the same rate.
  • You file Ohio income tax using Form IT 1040, which is due on the same date as your federal return — typically April 15.
  • Certain types of income, such as Social Security benefits and some retirement distributions, may be partially or fully exempt from Ohio tax.

Ohio's income tax brackets and rates

Ohio divides taxpayers into tax brackets based on filing status and income level. A single filer in 2024 pays 0.5% on income up to $25,000, then the rate increases in steps: 1% from $25,001 to $50,000, 2% from $50,001 to $100,000, 2.5% from $100,001 to $200,000, and 3.24% on income above $200,000. Married couples filing jointly have higher bracket thresholds but pay the same rates at each level.

The brackets adjust slightly each year for inflation, so the exact dollar amounts change. You can find the current year's brackets on the Ohio Department of Taxation website. Your employer typically withholds tax from each paycheck based on these brackets and the information you provide on your W-4 form.

What income is taxed in Ohio

Ohio taxes most types of income, including wages, salaries, tips, self-employment income, interest, and dividends. If you receive rental income from property in Ohio, that is also taxable. Capital gains — profit from selling stocks, real estate, or other assets — are taxed as ordinary income in Ohio, meaning they are subject to the same brackets as wages.

Some income is exempt or partially exempt. Social Security benefits are not taxed by Ohio. Distributions from traditional IRAs and 401(k) plans are taxed as ordinary income, but distributions from Roth IRAs are not. Military pensions and some federal pensions receive preferential treatment under Ohio law. If you receive unemployment benefits, those are taxable in Ohio.

How to file Ohio income tax

You file Ohio income tax using Form IT 1040, the Ohio Individual Income Tax Return. The form is due on the same date as your federal return, which is typically April 15. If you file your federal return early, you can file your Ohio return at the same time. If you need more time, you can request an extension, which gives you until October 15 to file.

You can file by mail or electronically through the Ohio Department of Taxation's website. If you use tax software like TurboTax or H&R Block, those programs can file your Ohio return at the same time as your federal return. Many people use a tax preparer or accountant to handle both returns together. If you owe money, you can pay online, by mail, or through an installment plan if you cannot pay in full by the important date.

Who must file an Ohio income tax return

You must file an Ohio return if you are a resident of Ohio and your income exceeds the filing threshold for your filing status. For 2024, a single person must file if they earned more than $1,250 in income. Married couples filing jointly must file if their combined income exceeded $2,500. These thresholds are lower than federal thresholds, so you may need to file an Ohio return even if you do not owe federal tax.

If you are not a resident but earned income in Ohio, you may also need to file an Ohio return on that income. Part-time workers, students with jobs, and self-employed people all have filing obligations if their income meets the threshold. Even if you do not owe tax, filing can result in a refund if too much was withheld from your paychecks.

Deductions and credits available in Ohio

Ohio allows you to claim a standard deduction, which reduces your taxable income. For 2024, the standard deduction is $2,500 for single filers and $5,000 for married couples filing jointly. You can also itemize deductions if they exceed the standard deduction, though Ohio's itemized deductions are more limited than federal deductions.

Ohio offers several tax credits that can reduce the amount of tax you owe. The Earned Income Tax Credit (EITC) is available to low- and moderate-income workers and is calculated based on your federal EITC. The Child and Dependent Care Credit helps offset childcare costs. If you have dependents, you can claim a dependent exemption. Seniors over 65 may may have access to for an additional exemption. You claim these credits and deductions on your Form IT 1040 when you file.

What happens if you do not pay Ohio income tax

If you owe Ohio income tax and do not pay by the important date, the state charges interest and penalties. Interest accrues at a rate set quarterly by the Ohio Department of Taxation. A failure-to-pay penalty of 0.5% per month is added to unpaid tax, up to a maximum of 25%. If you file your return late, an additional failure-to-file penalty applies.

The Ohio Department of Taxation can place a lien on your property, garnish your wages, or intercept your state or federal tax refund to collect unpaid tax. If you cannot pay in full, you can contact the department to set up a payment plan. Paying what you can, even if it is not the full amount, stops the failure-to-pay penalty from continuing to grow.

Frequently Asked Questions

Do I have to pay Ohio income tax if I just moved to the state?

You owe Ohio income tax starting the day you become a resident. If you moved partway through the year, you file a part-year resident return and pay tax only on income earned after you moved to Ohio. Bring documentation of your move date, such as a lease or utility bill, when you file.

Can I claim a credit for taxes I paid to another state?

Yes. If you worked in another state and paid that state's income tax, you can claim a credit on your Ohio return to avoid paying tax twice on the same income. The credit is limited to the lesser of what you paid to the other state or what you owe to Ohio on that income. You report this on your Form IT 1040.

Is retirement income taxed differently in Ohio?

It depends on the source. Social Security is not taxed. Distributions from traditional IRAs and 401(k)s are taxed as ordinary income. Military pensions and some federal pensions are exempt. Pension income from a private employer is taxable. Check with your plan administrator or a tax preparer about your specific situation.

What if my employer did not withhold enough Ohio tax from my paychecks?

You will owe the difference when you file your return. To avoid this next year, update your W-4 form with your employer and claim fewer allowances so more tax is withheld. You can also make estimated tax payments throughout the year if you have income that is not subject to withholding, such as self-employment income.

Do I need to file an Ohio return if I only earned a small amount of income?

Only if your income exceeds the filing threshold for your status — $1,250 for single filers in 2024. Even if you do not have to file, you may want to file anyway if taxes were withheld from your paychecks, because you could receive a refund.
