First time filers will not have an Illinois filing PIN. However, with a valid Illinois Driver's License or Illinois State Identification Card, you can still e-file your Illinois return. Married filing joint filers will be required to enter valid Driver's License or State ID information for the spouse as well.
Once a return is successfully filed with Illinois, an eight digit IL-PIN will be issued.
If you have successfully filed an Illinois return in a prior year, visit IL-PIN inquiry or call 800-732-8866 to see if an IL-PIN has been issued to you.
