Q. Will I need to file as a Ohio non-resident?
A. Maybe. Technically your situation is not covered by form IT-4 and some employers will withhold OH state tax. This causes you to have to file a non resident return for a refund. If no OH tax is withheld and you do not physically work in OH, you do not need to file an OH return.
I would check the box "I am exempt from Ohio withholding under R.C. 5747.06(A)(1) through (6)", if your employer is insisting you file it. Or add wording "Non resident working only out of state". I'm of the opinion that your employer is not required to get an IT-4 from you since you don't physically work in OH. If your situation is that you will occaisionally work in OH, then your emplyer would be correct to withhold some OH tax.
