Replying to recent response: It is not necessarily true that AZ spouse is considered to have CA income. It would have to be income with a source in CA. Income from pension or interest income does not count as CA source income. If CA spouse is still working though (e.g., self-employment), then AZ spouse would have CA source income and couple would have to file jointly in CA. In any case, the whole purpose of the mock federal returns is to generate the appropriate numbers for the individual MFS state returns, so the amounts on the CA forms would be those from mock MFS CA return.
