For the 2020 tax year, you must file if you are an Ohio resident, a part-year resident, or a nonresident who earned Ohio-sourced income. This includes wages earned in Ohio, income from a sole proprietorship, and certain gambling winnings. Filing on time is vital because it helps you avoid penalties, claim any refund you are owed, and maintain good standing with the state. Even if you qualify for exemptions, there may be reasons to file, such as school district income tax obligations.
Whether you choose to e-file or submit a paper return, knowing the required forms, deadlines, and payment options will save time and prevent errors. This article will walk you through every step—from gathering tax information to tracking your refund—so you can file efficiently. With clear instructions and practical tips, you will be ready to confidently prepare and submit your Ohio return for the 2020 tax year.
The Ohio state income tax for 2020 included several changes that affected who must file and how much tax they owe. Ohio adjusted its tax brackets so that individuals with taxable nonbusiness income of $22,150 or less were not subject to income tax. The year also saw the introduction of new credits and deductions, such as the Lead Abatement Credit and the Ohio Educator Deduction, which can reduce your tax liability if you qualify.
If you lived in Ohio for a whole year or part of a year or were a nonresident who earned money in Ohio, you need to file an Ohio income tax return. This can include money made in Ohio from work, the Ohio lottery or casino games, property in Ohio, or a sole proprietorship or pass-through business that does business there. Certain exemptions apply, but even if your income is below the threshold, you may still need to file for purposes such as the school district income tax.
The regular filing deadline for the 2020 tax year was April 15, 2021, but it was extended to May 17, 2021, to align with IRS changes. If you got an extension, you had until October 15, 2021, to send in your return. It is important to remember that an extension to the filing does not extend the time to pay. Late payments may result in interest and penalties, so plan to pay any balance you owe by the original due date.
The first step in filing your Ohio tax return for 2020 is to use the proper forms. The Ohio IT 1040 is the main form for filing your individual income tax. It shows your income, exemptions, deductions, and credits. You must also file the SD 100 School District Income Tax Return if you live in a school district that taxes its residents. Taxpayers without liability and not requesting a refund may qualify to use the IT-10 form as a simplified option.
Several schedules may be required depending on your situation. Schedule A shows changes to your federal adjusted gross income, such as additions or deductions. Schedule IT BUS applies if you have business income and want to claim the business income deduction. Other standard schedules include the Schedule of Credits for claiming nonrefundable and refundable credits, the Schedule of Dependents for listing dependents, and the Schedule of Withholding to report taxes withheld from wages, gambling winnings, or other income.
Payment vouchers are necessary if you owe tax and submit payment by check or money order. These include the IT 40P for original returns, the IT 40XP for amended returns, and the SD 40P and SD 40XP for school district taxes. You can find these forms on the Ohio Department of Taxation website, by calling 800 282 to request them by mail, or through the Innovate Ohio platform. Always use forms for the correct tax year—do not alter the year on an older form.
Filling out the Ohio IT 1040 correctly ensures your tax return is accurate and processed without delays. Follow these steps to prepare your return, whether you plan to e-file or submit a paper version.

Ohio accepts IRS extensions, so you don't need to ask for a separate state extension. If you obtained a federal extension, your Ohio filing deadline is extended to October 15, 2021. Include a copy of your IRS extension form with your Ohio return. Remember that an extension to the file does not extend the deadline to pay, so any balance you owe must be paid by May 17, 2021.
Yes, if you file a joint federal tax return, you generally file a joint Ohio return, even if one spouse moved in or out of the state. In such cases, you may need to allocate income using the part-year resident or nonresident credit to ensure only Ohio-sourced income is taxed. Carefully review the residency rules and complete the nonresident statement if applicable to your situation.
For 2020, temporary legislation treated income earned while working from home in Ohio due to COVID-19 as earned at your regular work location. This rule affected many nonresidents and residents who commuted before the pandemic. Review your W-2 and employer withholding information carefully. If you believe your withholding was incorrect, you may need to file an amended return to adjust your Ohio tax liability.
You must file the SD 100 School District Income Tax Return if you live in a school district with an income tax, even if you don't have to pay the Ohio IT 1040. To be sure, compare your address to the list in the Ohio tax instructions. If you moved between taxing districts during the year, you may have to file multiple school district returns.
