The DR 8454 is for electronic filing of returns. The DR 1778 is for submitting documentation through the mail or online with the department.

CO DOR:

The DR 1778 is the E-Filer Attachment Form from the Colorado Department of Revenue for attaching necessary documentation during e-filing. It helps taxpayers provide required documentation that cannot be submitted electronically. Use this form to ensure your tax credits are processed without delays.
