Box A is marked instead of B on the section below line 35, "Base income or loss," on Form IL-1065 or IL-1120-ST. This section is completed automatically based on your data entry:
Box A is marked if both of the following are true:
-
All of the base income or loss is derived inside Illinois.
-
There is no income or loss to report on line 36, 37, 44, or 45.
In this case, nothing carries to Step 6, and the amount from Step 5, line 35 flows to Step 7, line 47
Box B is marked if any of the following apply:
-
The base income or loss is derived inside and outside Illinois.
-
All of the base income or loss is derived outside Illinois.

There is income or loss to report on line 36, 37, 44, or 45.
In this case, all lines in Step 6 must be completed. See the IL 1065 or 1120-ST instructions for details.
Note NOTE: If the partnership or S corporation received a K-1 from another pass-through entity, the following amounts on IL screens K1P and K1T flow to the applicable line on Form IL-1120-ST or IL-1065, which causes box B to be marked:
