My clients were recently married and filed a joint return.  The taxpayer was NOT claimed as a dependent on his parent's return.  The wife, however, was legally claimed on her parent's return.  According to Ohio's official instructions, the Ohio exemption should be 1.  The taxpayer can claim an exemption, but the wife cannot.  Called Intuit; was told to override and complete the form accurately, then bypass the error review in order to e-file.  The return was rejected, as I expected.  The explanation from Intuit was that when EITHER the taxpayer or spouse is claimed as a dependent on another return, the Ohio exemption should be zero.  That is not correct.  Intuit programming has misinterpreted the instructions, which I verified with the Ohio Department of Taxation. I ended up paper filing because I did not know who else to contact to remedy this situation.
