Are you getting every property tax exemption you qualify for?

Exemptions lower the taxable value of your home before the tax rate is applied. They're often worth more than an appeal, and a missed one can usually be claimed for up to three past years.

How to check what you already get

Look at your second-installment tax bill: exemptions you received are listed on it.
Or look up your PIN on the Assessor's exemptions page, which shows each year's exemptions.
If one is missing, apply online with the Assessor. For past years, ask the Assessor about a Certificate of Error.

Amounts are the Cook County exemption amounts in effect for recent tax years; confirm on the Assessor's site. Savings are estimates: exemption × your tax rate. Without your rate we use 6.5% to 14%.
