State Information Data Exchange System (SIDES)

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 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.
