I filed and amended return for 2023.  I e-filed the federal but I need to mail the State of Missouri.  I did not get any instructions on what forms to include.  I think it's 1040X but do I need to mail the entire state forms?

    The answer is apparently YES (or almost so). 

     

    The instructions for filing a Missouri amended return are sparse:

    "To file an amended individual income tax return, use Form MO-1040. Select the box at the top of the form. Complete Forms MO-1040, pages 1-5 (pages 21-25 in the instructions) and the Individual Income Tax Adjustments (Form MO-A), pages 1-4 (pages 27-30 in the instructions), using corrected figures. Attach all schedules along with a copy of your federal changes and your Federal Form 1040X. 

     

    If you are due a refund, mail to: Department of Revenue, P.O. Box 500, Jefferson City, MO 65105-0500. 

     

    If you have an amount due, mail to Department of Revenue, P.O. Box 329, Jefferson City, MO 65105-0329."
