MFA required for electronic filing

Effective May 3rd, the 2017 version of UltraTax CS requires multi-factor authentication (MFA) to transmit e-files from CS Connect. Find out more.

Use this procedure to ensure the correct preparation of Illinois combined income tax returns if the members of the Illinois unitary business group are the same as those included in the federal consolidated group.

Note: If the combined unitary group contains members other than C Corporations, refer to 1120 Illinois frequently asked questions for information on how to prepare an Illinois unitary group return.

  1. Add Illinois to the parent client, the eliminations client, and the applicable subsidiary clients. Complete all data entry for these member clients. Each member's state return should be complete and correct before proceeding to the next step.

    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. Add Illinois to the federal consolidated client.

    Note: When adding Illinois to a consolidated federal client, the state automatically defaults to being a combined return.

    If the state is added as a C Corporation to a federal consolidated group, the consolidated functionality does not take place. The amounts from each member are not combined, and the combined forms are not available.

  3. Review all Illinois combined client input screens and complete any necessary remaining data entry.
  4. For each category not marked in the File > Client Properties > Advanced Properties > Options dialog, enter the necessary data in the applicable input screens.

    Note: If a category is not marked, enter the data on the applicable input screens in the combined client. For a list of categories and related input screens, see Categories and related Illinois input screens.

    Any changes made to the File > Client Properties > Advanced Properties > Options dialog affects both the federal and state return.

  5. Click the Combined folder in the Illinois folders block. Complete the necessary information in Screens ILAffil and ILComb.
  6. To make manual adjustments in other areas of the return, click the Group View button or press F7 in the input screen field you want to adjust, and then enter the adjustment amount in the Group View dialog.
  7. To change amounts entered in the Illinois parent, eliminations, or subsidiary clients, go back to the original source of data entry. For instance, if you made a mistake when you entered the apportionment of the first subsidiary, close the consolidated client and reopen the first subsidiary. Choose View > Apportionment for that client and correct the data. Close the subsidiary client and reopen the consolidated client. The correct amount is now a part of the consolidated group return.
  8. Print and review the Illinois combined tax return.
