Yes it saves them a lot of money so I definitely will fill MFJ for federal.  I was never going to claim credit for taxes pd to other jurisdictions because that is not the case here.  Neither tax was pd as a nonresident.  I was trying to avoid having to file a MFS for NY and PA, so I think I found a workaround by enter the spouse's income as $0 on the PA Gross Income Worksheet.  I know it's probably not right, but it works and gives me the results I know are right.
