IL-4506 Request for Copy of Tax Return
IL-4506 (R-02/20)
When should I complete this form?
You should complete this form if you need a copy of your tax return and any
attachment to that return. A separate Form IL-4506, Request for Copy of Tax
Return, must be completed for each tax type requested. There is a $5 charge
for each copy of the return, which includes all attachments, and an additional
$5 charge if you want the document certified.
What should I provide with this form?
You must submit a copy of a government-issued identification such as:
a driver's license,
a passport, or
another government-issued form of identification.
In addition, if you are not the taxpayer, please enclose a copy of your authorization
to receive this information. You may submit a power of attorney, tax information
authorization, or (if the taxpayer is deceased) a certified copy of your letters
of administration or testamentary. If more than one year has passed since the
letters were issued, you must also send a certification from the clerk of the court
stating they are still in effect.
What is certification?
Certification is confirmation that the reproduction of your tax return and any
attachment is true and correct. We will certify your copy by stamping the face
of the return. Certification usually is required only for judicial or administrative
proceedings or for attachments to another state’s tax return.
What is my identification number?
Your identification number is the series of numbers you used to file your
original tax document. You must use this same identification number to obtain
a copy of your tax return. The most common identification numbers used are:
Federal Employer Identification Number (FEIN) for all business, trust,
estate, and withholding tax returns;
Social Security numbers (SSN) for individual income tax returns;
Illinois account ID numbers for sales tax returns;
License numbers for motor fuel, cigarette, and liquor tax returns; and
Vehicle Identification Numbers (VIN). Attach a copy of the title if requesting
vehicle tax documents.
This form is authorized as outlined under the Illinois Income Tax Act. Disclosure of
this information is required. Failure to provide information could result in a penalty.
