In plain words.
Illinois taxes homes on an assessed value, and the state gives homeowners exemptions that lower that value: one for living in the home, one more from age 65, and for seniors with modest incomes a freeze that holds the assessed value where it was when they first applied. The amounts differ by county. This tool takes your county, your assessed value, your age, and your household income, and shows which apply and what each is worth in dollars at your rate.
Why it matters.
The senior exemptions are not automatic everywhere, the freeze needs a yearly form, and the saving is real money every year for as long as you own the home.
An example.
A Cook County home assessed at $60,000, owner 70, household income $50,000, frozen at $50,000, at an 8 percent rate: $28,000 of exemptions, about $2,240 a year saved on a $4,800 bill.
Where it stops.
The assessed value and the local rate come from your bill, and the freeze depends on when you first applied. It does not cover the exemptions for veterans or people with disabilities, or appeals of the assessment itself, which are the county's process.
