What is the Illinois Homestead Exemption Program, and who qualifies? 
There are seven different types of exemptions, this program will reduce or defer an increase in the equalized value of your property. The net effect of these exemptions is to lower the assessed valuation to which the tax rate is then applied. Qualifications and application procedures vary for each program. However, you must own the property to qualify for any of these exemptions.

Can I estimate the amount of my exemption?   
Yes. Here are some examples for 2023 tax year payable 2024.
Tax year 2022 payable in 2023 has lower exemption amounts for GHE & SHE.
