I have a little complicated situation.  I have a customer who lived in IL from Jan -Nov. Then moved to CA in Dec.  He rented an apt during the week in MO from Jan -May, but then worked from home in IL from May - Nov.   His W2 shows MO state wages the same as Fed but also a smaller state wages from CA (so adding his MO and CA income is more than Fed income).  Wife shows a W2 with all income from IL and 2nd w2 with income allocated to both IL and CA (adds up to Fed amt).  Looking for suggestions.  Sounds like I do nonresident for MO first, then IL, then CA.  Then I do a tax credit for taxes from other State on IL return?  Some for CA?
