The Colorado DOR has informed us that they will not begin processing e-filed returns until mid-February. Anticipated e-file processing start dates are as follows:

  • Individual – February 11, 2025
  • Business – February 10, 2025
  • Fiduciary – February 10, 2025

Once e-filing has been Approved,  you can complete and e-file Colorado returns, however, you will not receive any CO acks other than “pending – waiting for acceptance” until the Colorado DOR begins processing electronically filed returns.
