IL Tax Filing document requirements - mail-inversion

[bechicago90]

Hi.  Where can I find the list of required documents if I mail-in my IL Tax return?  I assume it's just a printed, signed copy of my 2022 IL 1040 Tax form and a copy of my  2022 W2.  Additional docs required?  Thx!

all w-2's and other withholding forms. if there are amounts, other than zero, on other lines the IL-1040 will state what form or schedule is needed

If you use TurboTax to prepare your state return, when you choose to print "All Official Forms Required For Filing", you will have everything that you need to include except for the copy of your W-2 and any other tax forms that show Illinois state tax withholdings (as mentioned by Mike9241).  There should also be an instruction sheet that will let you know where to mail the return.  

For further information, here is a link to the 2022 Illinois Income Tax Instruction Booklet.
