What should I attach to my IL-1040 if I cannot obtain copies of my W-2 forms?

If you are unable to obtain copies of your W-2 forms you may fill out  Form IL-4852, Substitute for Unobtainable Form W-2, and attach it to your tax return.  You must also attach proof of wages and withholding, such as copies of check stubs or a letter from your employer.

Your check stubs or letter should include the following information:  

  • your name,
  • your Social Security number,
  • tax year,
  • amount of Illinois Income Tax withheld, and
  • total wages.

We will accept a copy of your properly completed federal Form 4852, along with any required attachments, as proof of your Illinois Income Tax withheld from your wages.
