IL-1120-ST - Filing Electronically a Short Year 2023
Hello, I need to e-file an IL-1120-ST for a short year tax for a business that ended on 11/30/2023, but proseries is giving me an error message saying that "per Illinois Department of Revenue only returns with tax years ending between 12/25/2023 and 12/25/2024 can be electronically filed". That statement is wrong. Is anyone else experiencing this program error? Thank you for your help.
