Illinois-Cook County Program Overview

Cook County offers five property tax exemptions: homeowner, senior, senior freeze, persons with disabilities, and veterans with disabilities. All five programs require proof of identity, occupancy, and tax liability in 2021 (Senior Freeze also requires 2020 identification.) Once the homeowner and senior exemption is applied, it auto-renews each year — meaning you only have to apply once!

Homeowner Exemption

The Homeowner Exemption reduces the Equalized Assessed Value (the value you pay taxes on) by $10,000. The Homeowner Exemption is calculated by multiplying the savings amount ($10,000) by local tax rate.

Eligibility

You may be eligible if:
  • You either own or have a lease or contract which makes you responsible for the real estate taxes of the residential property
  • You occupy the property as your principal place of residence on January 1, 2021.

Application Deadline

Cook County second installment property tax bills for tax year 2021 will be mailed in late August. The anticipated due date is October 1.

Once this exemption is applied, the Assessor’s Office auto-renews it for you each year.

Required Documentation

Homeowners

  • The Cook County Assessor Exemption Application for Tax Year 2021

    • Being listed on the deed recorded at the Office of the Cook County Recorder of Deeds verifies property tax liability

    • Proof can be Illinois driver's license/ID card, Matricula Consular ID, City of Chicago ID card
    • Name and property address must verify the application

    • You may also be able to prove occupancy and identity by providing alternate forms of ID and documents such as a bank statement, utility bill, and social security award letter.

Senior Exemption

The Senior Exemption exempts $8,000 of assessed value from the owner’s tax bill. The Senior Exemption is in addition to the Homeowner Exemption. Those that qualify for the Senior Exemption automatically qualify for the Homeowner Exemption ($10,000).

Eligibility

You may be eligible if:
  • Must be born in 1956 or prior
  • You either own the property or have a lease or contract which makes you responsible for the real estate taxes.

  • If you are a surviving spouse and 65 or over, you will qualify for this exemption in your name and can apply online.
  • Otherwise, your property will receive the exemption for the remainder of the year of your spouse’s death. You will then have to apply when you turn 65.
  • A parent who passed away in 2021 is eligible if the parent was alive and resided in the home January 1, 2021 as the principal place of residence.
