Unemployment Insurance Tax - State Information Data Exchange System (SIDES) and E-Response

The State Information Data Exchange System (SIDES) and SIDES E-Response offer employers and third-party administrators (TPA) - free of charge - secure, electronic and standardized format to supply the information needed for responding to unemployment insurance (UI) benefit claim notices/information requests rather than by U.S. Postal Service mail.

SIDES and SIDES E-Response give employers an easy and efficient way to respond to UI information requests, saving time and money by:

  • Eliminating mail delivery allowing more time to gather information and respond timely.
  • Ensuring complete information is provided the first time reducing the need for phone calls.
  • Reducing paper handling, staff time and postage costs.

SIDES E-Response is a website through which employers and TPAs submit electronic responses to UI information requests. SIDES provides a more automated data-sharing and file-tracking interface between employers’ IT systems and state agency networks. SIDES is especially helpful to those who typically deal with a large volume of UI information and operate in multiple states. For more information on these two options, view a SIDES and SIDES E-Response Comparison Table (in Adobe PDF format).

For additional information on the SIDES computer-to-computer interface system, including how to sign up for it, view the SIDES Introductory Guide (in Adobe PDF format*).

To participate in the SIDES E-Response system, complete and submit the registration form. Once your registration is approved, all Notice of Claim information will be emailed to you at the address you provided on your registration form. A Personal Identification Number (PIN) and the website address for accessing the SIDES E-Response website will be provided in each email notification. If you change your email address or decide you no longer wish to participate, contact the Department at 605.626.2310.
