Prepare Illinois Unitary Business Group income tax returns

Follow these steps to prepare a Illinois Unitary Business Group income tax return consisting of C Corporation and S Corporation or Partnership members.
If the unitary group consists of both C Corporation members and S Corporation or Partnership members, use the following procedure to compete the unitary return.
  1. Add Illinois to all members of the unitary group. Complete all data entry for these member clients. Each member’s state return should be complete and correct before proceeding to the next step.
  2. Create a federal consolidated client by selecting all C Corporation member clients in the Advanced Properties dialog (accessed via File then Client Properties). When selecting the parent of the combined group, Illinois’s designated agent should be selected as the "Parent."
  3. Open the federal consolidated client return, and mark the
    Designated agent
     checkbox in the File, Client Properties, then Illinois tab. A Unitary input screen folder is now available in the list of Illinois input screen folders.
  4. In each S Corporation member return, choose the File, Client Properties, then Illinois tab, and enter the EIN of the designated agent client in the
    Designated agent EIN
     field.
  5. Print preview each S Corporation member return after adding the designated agent’s EIN to prepare each member’s state return information to share data into the designated agent’s return.
  6. Open the federal consolidated client return and navigate to the Illinois input screens. The Data Sharing – Pending Updates dialog opens listing each member client available for data share.
  7. Select the first member and press
    Add Unit
      at the bottom of the Data Sharing dialog. You will now see a list of the data to be imported into the federal consolidated client. Select the
    Accept and import new source data
     option and press
    Accept
     at the bottom of the dialog. Repeat this step for each member of the unitary group.
  8. Select the Illinois Unitary input screen folder. There is now a separate unit for each member client with shared data in step 7.
  9. Review each unit of the Unitary input screens and complete all necessary information in the following input screens: ILAffil, ILComb, ILUMemb, ILUInc, ILUAdj, and ILUAppt.
  10. Print and review the Illinois Unitary Business Group income tax return.
  11. S Corporation and Partnership members must file a copy of the designated agent’s Schedule UB with their separate Forms IL-1120-ST and IL-1065 with combined amounts. Enter the combined additions and subtractions for the group on the ILUMod Screen in each member client return.
