Who Is Required to File a Tax Return in Ohio?

Wondering if you have to file taxes in the Buckeye State? The answer is simple. All full-year and part-year residents must file an Ohio tax return if they earned money in the state. Nonresidents must also file if they have Ohio-sourced income. This includes:

• Ohio lottery and casino winnings;
• Ohio sports gaming winnings;
• Income or capital gains from Ohio property;
• Income or gain from a sole proprietorship doing business in Ohio; AND

Exception:Full-year nonresidents living in Indiana, Kentucky, West Virginia, Michigan, or Pennsylvania do not have a nonresident return if their only Ohio-sourced income is wages.
