- Resident. You were a resident of Ohio if you lived in Ohio for the entire year. If you were away temporarily, you were still a resident of Ohio.
- Part-year resident. You moved into or out of Ohio during 2018, not counting being away temporarily.
- Nonresident. You were domiciled outside of Ohio all year.
Caution: Part-year residents should use the nonresident credit on the Ohio Schedule of Credits (as explained in the 2018 Ohio income tax instructions) for income earned while a resident of another state. Individuals who earn or receive income within Ohio will be able to claim the nonresident credit with respect to all items of income not earned and not received in Ohio.
If you are unsure of your state of residency, Ohio law provides that you will be considered a full-year nonresident of Ohio only if you meet all five of the following requirements:
- During the entire taxable year you had at least one abode outside of Ohio,
- You spent no more than 212 contact periods in Ohio during the taxable year,
- You were not a part-year resident of Ohio during the taxable year,
- By May 30th of the immediately succeeding calendar year you file, as appropriate, either the affidavit or notice of non-Ohio domicile or notice of no Ohio income tax liability (below),
- These documents do NOT contain any false statements.
