Individual Income Tax

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.

Exception
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.
