Grant Third-Party Administrator (TPA) Access in Illinois

A Third-Party Administrator (TPA) is an external organization or service provider that manages payroll and employee benefits on behalf of a company. To comply with Illinois state regulations, 7shifts Payroll customers must grant Check (our payroll processing partner) TPA access to the Illinois MyTax portal. This enables Check to handle payroll-related communications directly with the department on your behalf.

Note: Confirm that Check Technologies has TPA access for the current year and upcoming filing periods. Access can have a prescribed end date or extend indefinitely. Update or renew the access as needed.

Steps to Authorize Check as Your TPA in Illinois:

  1. Log in to MyTax Illinois
  2. Navigate to Settings → Manage Third Party Access
  3. Set:
    1. Allow = Yes
    2. Default Access = Third Party
    3. Default Account Access = Full Access
