    What is an Examiner's Report?

    The Examiner's Report (EDA-131), is a detailed notification of the proposed changes made to your Illinois Income Tax Return.  The information in this report should be compared to your federal and state tax records for accuracy. If you agree to the proposed tax due or to claim the proposed refund, sign this document and return it to the IDOR.  If you disagree, see below.

    If you are changing the federal tax information such as the federal adjusted gross income, filing status, exemptions, or earned income tax credit, we will accept an IRS Account Transcript as support to correct your federal tax information. You may obtain your IRS account transcript by visiting www.irs.gov/individuals/get-transcript and using the "Get Transcript Online" option.
