My ILLINOIS state return was rejected due to the AIG not matching last year. This data was accurate that I was entering. I don't have the code , but it starts with IL-1040 then 4 more number. Here is what you can do. Get your PIN online. MyTax Illinois They tell you this is mailed to you, well, I never saw anything like this. Just go online, get the 8 digit pin. When you are refiling, do not fill in your AIG from last year, instead click the box on the bottom that says something like I don't have my aig or i want to file differently, going off of memory here. It will pop up a box that can enter either you pin or DL #,...you can only enter one. I entered the pin, then finished refiling and it was approved in less than 8 hours. Hopefully this helps my fellow Illinois folks!!!!
