MO - Missouri Income Percentage, Form MO-NRI



I completed Form MO-NRI; however, Form MO-1040 still shows my Missouri income percentage as 100%. Why?

If MO is listed as the resident state on federal screen 1, then the Missouri income percentage will always be 100%. For the income percentage calculated on Form MO-NRI to flow to the MO 1040, the resident state selection on federal screen 1 has to be either PY, or a state other than Missouri. 

MO screen NRI has two main parts, Part A and Part B.  

  • For Part A, only the applicable section (Part A1, A2, or A3) should be completed by the taxpayer and/or spouse.
    • A nonresident of MO will complete Part A1, line 1.
    • A part-year resident of MO will complete Part A2, lines 2a and 2b.  
    • A nonresident member of the military will complete Part A3, either line 3a or line 3b. 
  • Part B is the Worksheet for Missouri Source Income.
    • The amounts for the income items listed generate based upon the state selection on the data entry screens for the income items.
    • Overrides (=) and adjustment fields (+/-) are provided for any needed changes.

The Resident or Non-Resident decision table from the Form MO-NRI Instructions can be used to help determine residency status:
