To e-file an Illinois tax return, you (and/or spouse) must have:
Note. If you (and/or spouse) have not filed an Illinois tax return within the past two years and you (and/or spouse) do not have a valid Illinois driver's license or Illinois State ID, you must paper file your Illinois return. However, you (and/or spouse) should be assigned an IL-PIN to e-file next year. See the Illinois File 2020 IL-1040 electronically through a Tax Professional webpage for more information on these requirements.
Note. If your return is rejected with Reject Code IL1040-8000-2, IL1040-8000-2, IL1040-10500-3 or IL1040-9900-2, the signature alternative for the taxpayer (and/or spouse) does not match the IDOR Records.
Your (and/or spouse’s) alternative signature options depend on whether or not you have filed an Illinois tax return within the past two years.
If you filed an Illinois tax return within the past two years, the IDOR should have provided you with an Illinois Personal Identification Number (IL-PIN) on your IL-1040 booklet or on a postcard. To obtain your IL-PIN, visit the IL-PIN Inquiry website or call 1-800-732-8866.

For your signature alternative, each of the following must be entered exactly as shown on your Illinois driver’s license or state ID:
