Some processes documented in the Help & How-To Center are no longer applicable, due to the discontinuation of Creative Solutions Accounting.

UI-3/40, UI-40A, IL-501, IL-941, and IL-W-3

You must first register with the Illinois Department of Revenue. You will need to complete Form IL-8633-B (Business Electronic Filing Enrollment) to register with Illinois to file as a reporting agent and obtain Form IL-8655 (Reporting Agent Electronic Services Authorization) for each client on whose behalf you will be filing returns. Form IL-8633-B must be filed with Illinois and Form IL-8655 must be retained in your files.

If you were to fail to register with Form IL-8633-B, any forms you transmit would be rejected.

  1. Choose Setup > FSET Transmission > Client when the Illinois Payroll Tax Processing window is active. Enter the appropriate information and click OK
  2. Choose Setup > FSET Transmission > Firm, enter the appropriate information and click OK.

    Note: The information entered in the FSET Firm dialog is global and will apply to any other Illinois clients.

  3. Choose File > Print.
  4. Mark the Queue checkbox next to the form(s) you would like to e-file and then click OK.
  5. Choose File > FSET Utilities > Queue Maintenance to delete any files prior to transmission via CS Connect.
  6. Choose File > FSET Utilities > FSET Maintenance to view or delete any return or acknowledgement files.
  7. When you are ready to send your files to Illinois, click the Done button to close the Payroll Tax Processing dialog and then choose File > CS Connect.
  8. In the CS Connect dialog, mark the Transmit returns checkbox in the Electronic filing section. Use the Electronic filing tab to select the files to be sent and then click the Call Now button.

    Note: The Transmit returns checkbox will transmit both state and federal files. If you would like to send only IL files, you should use the Electronic filing tab to select them for submission.

  9. Once Illinois has accepted or rejected your file(s), you will receive an acknowledgement file via CS Connect. To download the acknowledgement file, open the CS Connect dialog, mark the Retrieve acknowledgements checkbox in the Electronic filing section, and click the Call Now button.
  10. If acknowledgements were downloaded, you can view them in the FSET Maintenance dialog by choosing Utilities > Payroll Tax Processing, selecting Illinois, and then choosing File > FSET Maintenance.
