State tax filing

This is 2026 and e-filing handles things behind the scenes. 

  • Most state returns, including yours, are filed with a federal return.
  • The detailed list is transmitted as part of the electronic record for MO A, line 8
  • The MO DOR has a copy of your 1099 data (federal state exchange program).
  • E-filers have the digital data, paper filers will need to complete those steps listed.

As for the mutual funds, if you followed the steps and entered income subtracted with a description -as you went through the program, then you have identified, described and met the requirements. If you have checked your return and it is accurate, you can safely file knowing the rules are met.

Great question! Sharp!
