According to MO DOR (refer to form MO-NRI pg 3 diagram) https://dor.mo.gov/pdf/nonres_flowchart.pdf
I am considered a Nonresident - since I answered NO to question 1 -" Are you domiciled in Missouri?" and then also answered NO to question 2 of having spent more than 183 days in MO.
That said - Nonresidents are required to pay income taxes on MO source income - hence my original question. Is an IRA withdrawal (taken during my "less than 183 days spent in MO") considered MO source income?
