The State Information Data Exchange System (SIDES) is a convenient and secure way for employers (or their agents) to electronically receive and respond to requests for information regarding unemployment insurance benefit claims.  Use of SIDES is free. 

Benefits of using SIDES include:

  • Quicker notification of claims filed and potential charges to your employer account.  Know who has filed for benefits right away versus waiting for the mail to arrive. 
  • Greatly reduces any forfeiture or rights to protest benefits due to lost or late responses.
  • Nationally consistent format for any size business. Eliminates submission errors and improves the quality of data provided. 
  • Enhances the integrity of the UI system.  Better responses in a shorter time frame help to reduce waste within the UI program and stop fraud.

  • We strongly encourage all employers to utilize SIDES. Using SIDES to respond to benefit claim information requests saves both time and money for Montana employers and the state. It also better ensures the security and accuracy of the information being exchanged. Our goal is to one day have all benefit claim exchanges of information done electronically.

    Employers new to Montana UI and existing Montana employers who are new to eServices (and not already participating in SIDES), will be required to sign-up for SIDES during the registration and/or access request process on eServices. Existing eServices users, who are not already participating in SIDES, will be prompted to enroll when you log in to eServices. If using SIDES will not work for your business, you may contact our office to unenroll.

  • SIDES is compartmentalized into exchanges based on the type of claim issue being investigated or information being requested. Currently Montana is participating in SIDES exchanges for:

    • Separation Information,
    • Monetary and Potential Charging,
    • Earnings Verification Reviews,
    • Determinations and Decisions (or Redeterminations), and
    • Additional Fact Finding.

    With the Determinations and Decisions exchange participating employers can review determination and redetermination notices and electronically request a redetermination or appeal via SIDES. Decisions above the redetermination level are not available through SIDES and will be mailed directly to the parties.

  • You might. Not all requests for information can be handled electronically through SIDES. For those that cannot, you will receive paper notices. As Montana and NASWA bring on additional SIDES exchanges, more and more requests will be done electronically reducing the amount of paper notices you’ll receive. It is important you continue to respond to all notices timely and appropriately regardless of how they are received.

  • No. For claims initiated prior to your enrollment in SIDES and/or issues not currently supported via SIDES, you will need to respond as directed on the paper notice.

  • I’m a Third-Party Administrator (TPA) but not a Broker; can I use SIDES to respond on behalf of my clients?

    Yes. TPA’s who are not SIDES brokers but are authorized to respond to benefit claim requests on behalf of their clients, may utilize eServices to link to SIDES E-Response. An authorization form, specifically authorizing eServices SIDES access, will be required.

SIDES Brokers

  • A SIDES Broker is typically a large employer or third-party administrator (TPA) who responds to benefit claim information requests on behalf of multiple employers (clients). Instead of logging into a website to receive or respond to requests, electronic files are securely exchanged between brokers and Montana UI.

    To exchange data with Montana (via SIDES), brokers are required to sign a Memorandum of Understanding (MOU) confirming they are authorized to respond on behalf of the employers they represent. They will also provide us with a list of their clients. Employers who utilize a broker to respond to requests for benefit claim information requests will not receive email notifications regarding the requests.

    Becoming a broker does involve system development, testing, and certification coordinated through the national SIDES team with NASWA.
