Thank you! The taxpayer is to file CT part year/nonresident tax return and the spouse is a full year resident.  Should I make a copy of their file and do the MFS from that file? I guess I would have to make two copies so I can input the spouse's information from the second copy, the husband's and file the two state returns from those files.  File the federal from the original.  I am guessing this cannot be done electronically.
