State tax filing

...AND...MO is one a few states where part-year residents of MO are supposed to, & allowed to file either as:

 

1) Full year residents, taxing ALL yearly income, but taking a credit for the taxes paid to the "other" state

or as

2) Full year non-residents, where you allocate what income you got after moving to MO.

 

Make sure you are using the Non-Resident route...#2. 

(not sure how the software asks you which way to use, but it should be at the very beginning of the MO Q&A)
