multiple state returns

[KJM14]

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?

Sounds right....

1) was resident of IL but worked in MO   therefore IL part year resident return  and  non resident MO 

2) was resident of CA (worked in CA?)    therefore CA part year resident return
