For 2015, you were a part year resident of both states and the reciprocal agreement did not apply to you.
For 2016, and beyond, assuming your have established Indiana residency (drivers license etc); Ohio has a reciprocal agreement, on wages, with all
neighboring states. No Ohio
state taxes are withheld or due and you do not need to file an OH return. But
your home state will tax you on your Ohio
income.
If Ohio
taxes are mistakenly withheld, you have to file an Ohio return to get a refund. You should ask
your employer to stop withholding so you don't have to file an Ohio return every year.
However the
reciprocity agreement does not apply to Ohio city taxes. You are not required
to file a local city return, but you are also not entitled to a refund of the
city withholding (box19 on your W-2), unless there was an error in the amount. Some (but not all) IN
counties also allow a credit, or partial credit for tax paid to an OH city.
Those items will come up in the IN state interview.
