In 2007, I lived in Missouri, but was a member of the Army Reserve in Illinios. I received a re-enlistment bonus from the Army Reserve in Illinois, and paid out the wahoo in taxes before I got the actual bonus. When I filed my MISSOURI STATE TAXES, am I supposed toinclude this income from Illinois to my Missouri State Taxes form?

Yes, because, as a resident of Missouri, all of your world-wide income is subject to Missouri state income taxes.
