Problem: The Illinois State - not eFile.com - has rejected the secondary taxpayer driver license signature field must be exactly has shown on record.
Solution: Sign into your eFile.com account at https://mytaxes.efile.com/1040/SignIn/ and click on My Return, and follow the instructions on the right side to correct this. You can either correct the spouse's Illinois driver's license/state ID information or use a different signature verification method on your Illinois return (follow the Try This First instructions in this article for the spouse). Note: If the spouse didn't file an Illinois return in 2014 and 2015, his or her Illinois driver's license/state ID is the only signature verification method available to them. If they don't have this, you'll be filing a paper return this year. Next year, however, you should be able to e-file.
After that you can re-eFile your federal and state returns at no additional charge.
