First, make sure all income is properly allocated between spouses. Then do a "Save As" , create new file under a different file name, and swap names and personal info on the federal worksheet, and reallocate income. Then simply choosing MFS as the filing status should include only taxpayer income on each return. You may need to do further tweaking--when I tried this, ProSeries gave errors on the W-2's that were assigned to the spouse, and I needed to remove them. I know this is kind of a clunky way to do it, but I don't know of a better way unless someone else does. Would be nice if you could do it with only one file.
