Illinois 2026 filing changes

Illinois returns follow the new structure without any action from you.

Starting with 2026 filing periods, Illinois requires food and drugs to be reported separately. They were previously combined as food, drug, and medical. Zamp's Illinois summaries now follow the new structure.

On Form ST-1, Line 5 is split into drugs and food. Schedule A Line 2 is split into 2a and 2b, and the ST-2 multiple site form has separate drug and food columns. Summaries for 2025 and earlier are unchanged.
