If the unitary group consists only of S Corporation and Partnership members, use the following procedures to prepare a unitary return.

  1. Create and complete each member client and add Illinois to each member.

    Note: Apportionment data entry must be completed for each member client, even if the client is 100 percent in-state. The same apportionment method must be used by the parent client and applicable subsidiary clients. Apportionment data entry is accessed through View > Apportionment.

  2. Open the S corporation acting as the designated agent for the unitary group. Mark the Designated Agent checkbox in File > Client Properties > Illinois tab in the Unitary group box.

    Note: To determine the designated agent for the group, refer to the Schedule UB instructions.

  3. With the designated agent’s return open mark the Designated Agent checkbox in File > Client Properties > Illinois tab under the Unitary heading. Print preview the return.

  4. Open each S Corporation member and enter the Designated Agent’s EIN in the Unitary return group box in File > Client Properties > Illinois tab. Print preview each S Corporation member return after adding the designated agent’s EIN. This stores off the member’s data for use in the designated agent client.

    Note: Data is not shared between 1120-IL and 1065-IL.

  5. Open the designated agent’s return and accept the shared data from each S Corporation member. Complete all necessary information in the following input screens: ILAffil, ILComb, ILUMemb, ILUInc, ILUAdj, and ILUAppt.

  6. Print and review the Illinois unitary group tax return.

  7. S Corporation and Partnership members must file a copy of the designated agent’s Schedule UB with their separate Forms IL-1120-ST or IL-1065 returns with combined amounts. Use Screen ILUMod in each member client to enter the combined additions and subtractions for the group.
