The 2024 Colorado W2 Electronic Filing Specifications in the CDOR-EFW2 Format are now available on the state department of revenue website by visiting https://co.colorado.gov/ .
W2 Mate 2024 software has been updated to incorporate the latest specifications and allow Colorado filers to generate the W2 E-File submissions, ready for upload to Colorado’s “Revenue Online” service.
Here’s a sample 2024 Colorado State Record (RS) for an employee named John L Doe, with Colorado state wages of $37,500.00 and tax of $1,270.00:
