2023 IL-1040 Schedule IL-WIT Instructions

Schedule IL-WIT, Illinois Income Tax Withheld, allows you to enter your withholding information in one place and calculate total Illinois withholding.

If you enter an amount on Form IL-1040, Line 25, attach a copy of your Schedule IL-WIT and all your Forms W-2 and 1099 showing Illinois income and withholding.

If you received more than five W-2Gs from the same payer, add the amounts for Columns C, D, and E from all W-2Gs issued by the same payer FEIN reported in Column B and report only the total in each column. See the form reference tables below to determine which boxes should be reported in Columns C, D, and E.

If your withholding form does not show Illinois income or withholding, do not include it on this schedule. However, if the withholding form provides verification of amounts reported on lines other than Line 25 on your form IL-1040, attach a copy of the withholding form to your return. Examples include:

• A military W-2 received for combat pay that does not include Illinois withholding but supports the subtraction reported on Schedule M, Line 21.
• A W-2 from an out-of-state employer that does not include Illinois withholding but supports the foreign tax credit claimed on your Schedule CR.
• A 1099-MISC form that does not include Illinois withholding but supports the non-employee compensation reported as business income (or loss) on your US 1040, Schedule 1, and Schedule IL-E/EIC, Line 2.
