Colorado W2 Electronic Filing Software

Generate EFW2 Files that comply with CO Electronic Filing Specifications

Colorado small businesses and filing agents can use our W2 Mate software in order to generate W-2 Electronic filing submissions that comply with the Colorado Department of Revenue CDOR EFW2 Specifications. Colorado employers with greater than 250 employees are required to submit electronically. Those businesses with fewer employees may submit W-2s electronically or file paper W-2 statements. To file electronically through the Department’s Web site users must follow the procedures and specifications outlined in Colorado (FYI Withholding 6 Methods of Filing Colorado Annual W-2 Tax Data). By the last day of March employers must submit to the Colorado DOR any W-2 statement by secure electronic submission.
