Q I filed Missouri resident on my taxes for the past two years because that it where I was living. Did I do right in filing as a FULL YEAR Missouri resident?
A. Probably. But, at a minimum, you should have filed as a part year resident of both states, for both years.
Q. Or should I have filed Illinois?
A. The fact that you maintained your IL drivers license, voter registration, car registration and had an IL address to return to (and it appears that your intent was to return) would make a case for you filing as an IL resident return, instead of MO (this assumes your job was located in IL).
