The State of Illinois offers a State Property Tax Credit. It is not contingent on your Federal Return status.
It would be in the "Tax Credit Section" of your State Return. Select State (Property) Tax Credits and follow all of the prompts.
The Illinois Property Tax Credit is a credit on your Illinois state income tax return (Form IL-1040) equal to 5 percent of Illinois Property Tax (real estate tax) you paid on your principal residence. You must own your residence in order to take this credit.
Individuals can claim a credit against personal income tax liability for part of the real property taxes paid during the tax year on a principal residence in Illinois. ( 35 ILCS 5/208; Publication 108, Illinois Department of Revenue, February 2018)
Taxpayers cannot claim the credit if their federal adjusted gross income for the tax year exceeds:
$500,000 for taxpayers filing a joint federal return; or
$250,000 for all other taxpayers.
When determining the credit, taxpayers can include:
property tax paid on a lot next to the principal residence if the taxpayer uses it for residential purposes;
prorated property tax paid in the year a taxpayer sold his or her principal residence;
village tax paid in the tax year;
multi-unit property tax paid, but only on the unit used as a principal residence; and
back property tax if the tax was paid during the current tax year. ( 35 ILCS 5/208; Publication 108, Illinois Department of Revenue,
