E-file rejection error IL1040-8000-2 or IL1040-9900-2: Please review and correct your signature requirements...

Your e-filed Illinois state return is rejected with one of these errors:

IL1040-8000-2: Please review and correct your signature requirements. At least one of the following signature fields must be present and valid on the Dept. Of Revenue's file: Primary Signature, IL Shared Secrets, IL PIN, Prior Year AGI, Driver's License, or State ID Number or Zip Code.

IL1040-9900-2 : Please review and correct the Secondary taxpayer's signature requirements...

This rejection occurs if the signature info you entered on the Illinois e-file agreement doesn't match what's on file with the Illinois Department of Revenue.

Try This First (Recommended)

  1. Open your tax return, if it's not already open.
  2. Click File and proceed to the Sign Your Illinois Return screen.
  3. On this screen, select I don't have my Illinois 2015 Adjusted Gross Income.
  4. Enter your signature information in only one of the signature option fields, leaving the others blank:
    • 2015 AGI from line 1 of your 2015 Form IL-1040 (not your federal AGI); or
    • 8-digit Illinois PIN, which you might be able look up at the Illinois Department of Revenue's website; or
    • Illinois driver's license number or Illinois State ID (info from other states won't work for Illinois). 
      • Note: If you didn't file an Illinois return in 2014 and 2015, this is the only signature option available to you. If you don't have an Illinois driver's license or state ID, you'll be filing a paper return this year.
    • If you are unable to supply any of these items, STOP. You cannot e-file this year. Click Back until you get to where you can change your filing option to file by mail.
  5. Click Continue and follow the onscreen instructions to resubmit your return.

If your return gets rejected again with the same error, try a different signature option in Step 4, or proceed to Other Options, below.

Other Options

If you've tried signing your Illinois return with information you know is correct, and you still keep getting rejected, you'll need to file a paper return this year.

Illinois will continue rejecting your return because your data doesn't match what they have on file.

Regrettably, we are unable to assist you further, as the problem lies with government agencies' data that we have no control over.

After mailing your return, we suggest you follow up with the Illinois Department of Revenue and request that they correct their records so you can e-file next year.
