Who Must File
Every Ohio resident and every part-year resident is subject to the Ohio income tax. Every nonresident having Ohio-sourced income must also file. Examples of Ohio-sourced income include, but are not limited to, the following:
- Wages earned in Ohio (note: see "Exception," below),
- Ohio lottery winnings;
- All Ohio casino gaming winnings;
- Income or gain from Ohio property:
- Income or gain from a sole proprietorship doing business in Ohio; and
- Income or gain from a pass-through entity doing business in Ohio.
A full-year nonresident living in a border state does not have to file if the nonresident's only Ohio-sourced income is wages received from an unrelated employer.
You do not have to file an Ohio income tax return if ...
- Your Ohio adjusted gross income (line 3) is less than or equal to $0.
- The total of your senior citizen credit, lump sum distribution credit and joint filing credit (Ohio Schedule of Credits, lines 4, 5 and 12) is equal to or exceeds your income tax liability (Ohio IT 1040, line 8c) and you are not liable for school district income tax.
- your exemption amount (Ohio IT 1040, line 4) is the same as or more than your Ohio adjusted gross income (line 3) and you have no Ohio Schedule A adjustments.
NOTE: IF your federal adjusted gross income is greater than $13,200, the Department recommends that you file an Ohio IT 1040 or IT 10, even if you do not owe any tax, to avoid delinquency billings.
OHIO IT 10: Certain taxpayers can file the Ohio Income Tax Information Notice (form IT 10) instead of the Ohio IT 1040. Form IT 10 lists six types of eligible reasons to file this form.
