Wage reports can be submitted via the Secure Transport File Transfer Protocol (FTP) application. Note that you may submit only wage reports via FTP, premium reports (Form UITR-1) must be submitted via MyUI Employer or by U.S. mail with the paper form.

Colorado will be making changes to the FTP file format later this spring. The good news is that those changes will not be implemented before the first quarter due date.

As a reminder, you currently provide 03, 06, 09, or 12 to represent the 1st, 2nd, 3rd, or 4th quarter, along with the year, in the format QQYYYY. With the upcoming change, you will need to provide the year first, and the quarter next as 01, 02, 03, or 04, in the format YYYYQQ.

*Example for 4th quarter of 2019:

  • Current format: 122019

  • New format: 201904

We will also be making another change later this spring for employers who submit wages for only their Employer Account Number using FTP. In order to continue to use FTP, those employers will have to register with MyUI Employer.
More information will be emailed to you in the near future.
