​​​What is SIDES?​

SIDES, or the State Information Data Exchange System, provides employers and third party administrators a secure, electronic and natio​nally-standardized format to respond to Unemployment Insurance information requests.
  • Free of charge: This system is offered free of charge to Employers or TPAs
  • Reduces administrative costs: This system reduces the volume of time-consuming follow-up phone calls, unnecessary appeals, postage costs, paperwork and staff resources
  • Secure: This system has multiple layers of security to protect the sensitive data exchanged between the Oregon Employment Department and employers or TPAs
  • Ensures accurate information exchanges: This system ensures that complete information is provided through standard edits, validations and business rules
  • Saves time: This system is electronic so it eliminates the delays related to paper mail delivery, reduces paper handling and ensures information requests are fully completed

If you are an employer with few UI claims throughout the year, the SIDES E-Response website gives you an easy portal to electronically submit responses to information requests from state agencies. E-Response is available to any employer or third-party administrator with Internet access.

For employers and third-party administrators that deal with a large amount of Unemployment Insurance information requests, SIDES provides a more automated data-sharing and file-track interface between employers' IT systems and state agency networks. SIDES is especially helpful for those who operate in multiple states.

SIDES and SIDES E-Response have the potential to significantly improve the exchange process, and saves time and money by:

  • Eliminating delays related to paper mail delivery, and allowing more time to gather information and respond;
  • Ensuring more complete information is collected, reducing follow-up phone calls;
  • Reducing paper handling, staff time and postage costs; and
  • Keeping Unemployment Insurance payroll taxes lower by reducing improper payments

What is it?

When a person files an initial claim or restarts an existing claim, the most recent employer receives a Notice of Claim Filed.

If a claimant did not work and earn four times the weekly benefit amount from his or her last employer, we will also mail a Form 220 to the next-to-last employer.

When you receive the Form 220:

Mail or fax the completed form to the Oregon Employment Department within ten days after the date we mailed the form. This protects your appeal rights.

Why should I respond?

Our adjudicators investigate separation and eligibility issues. We rely on you, the employer, for much of our information. Your timely response to this notice entitles you to a decision you can appeal if an issue exists that may affect the person's eligibility for benefits. If a claimant stopped working for you for any reason other than lack of work, provide details of the separation in the space provided and use the back if necessary. Please be sure your information is correct and true. Willful false statements can result in additional charges against your account.

Your response is very important. The facts surrounding an employee's separation can directly affect your tax rate because we decide to pay or deny benefits based, in part, on this information. Without your response, we must make a decision based on available information. Decisions to allow benefits affect all base year employers. Benefit charges may affect tax rates or contributions as a result of a person's most recent separation.​
