Please Note: The Senior Freeze Exemption freezes the Equalized Assessed Value (EAV) of a home. A property's total tax bill depends on the EAV and the tax rate. Because the tax rate is calculated each year and can change each year, so can the property tax bill. It is important to note that the exemption amount is not the dollar amount by which a tax bill is lowered. EAV is the partial value of a property to which tax rates are applied; it is this figure on which a tax bill is calculated. The Assessor does not set tax rates.

1. Proof of age and identity and occupancy in 2025.

• A copy of one photo ID from List A must be provided along with an Occupancy Affidavit (the affidavit is provided within the online application).  The name and property address must match the application and the date of issue must verify that you occupied this property in 2025.

• List A: Photo IDs that verify identity and occupancy • Illinois Drivers License / ID Card • Matrícula Consular ID • City of Chicago ID Card

         If the address on your photo ID does not match the property address, include a copy of one document from List B and one from List C, and an Occupancy Affidavit. 

• List B: Photo IDs that verify identity and date of birth • Illinois Drivers License / ID Card • Matrícula Consular ID • City of Chicago ID Card • Passport • Certificate of Naturalization (N-550/N-570) • Permanent Resident Card (I-551) • Refugee Travel Document (I-571) • Employment Authorization Card (I-766)

  List C: Documents that verify 2025 occupancy • Bank statement • Landline, cable, or internet bill • Pay stub or Social Security Award letter • Voting record from 2025 (from Cook County Clerk’s office or Chicago Board of Elections)

     2. Proof of Property Tax Liability

• If you are listed on the deed recorded at the Cook County Clerk's Office, this verifies your property tax liability. The Assessor’s Office staff can verify recorded deeds for you, so you do not need to provide a document.
   
• If you are NOT listed on the recorded deed, please provide one of the following documents to verify you are liable for payment of property taxes for this property:
  • Deed (if not recorded) or contract for a deed
  • Lease
  • Trust Agreement
  • Stock Certificate
  • Occupancy Agreement
