According to the Missouri Department of Revenue, "The Military Spouses Residency Relief Act, effective for the 2009 tax year and forward, prevents income earned by service members’ spouses from being taxed by any state other than the state they declare as their state of residence. If you are the spouse of a military service member, are in Missouri because the military service member is stationed in Missouri on military orders, and your state of residence is another state, any income earned by you is not taxable to Missouri. "
