A Homeowner Exemption provides property tax savings by reducing the equalized assessed value of an eligible property. Most homeowners are eligible for this exemption if they own and occupy their property as their principal place of residence. Once the exemption is applied, the Assessor’s Office auto-renews it for you each year.

Automatic Renewal: Yes, this exemption automatically renews each year. 

How can a homeowner see which exemptions were applied to their home last year?
Check the Cook County Portal website, then review the Exemption History and Status section.

? Reminder: Exemptions appear on your second installment tax bill issued in the summer. To learn more about how the property tax system works, click here

Frequently Asked Questions

Info Tab Content

I have never applied for the Homeowner Exemption. How do I do that?
If you have never received a Homeowner Exemption on your home, you will need to file an initial application. Exemption forms may be filed online, or you can obtain one by calling one of the Assessor's Office locations or your local township assessor. 

Do I have to apply every year?
No. Once you apply, the Homeowner Exemption will renew automatically in subsequent years as long as your residency remains the same. 

Can I receive a prorated exemption if my home is new construction and I move in after January 1?
This exemption will be prorated if you purchased a newly constructed home that was not ready for occupancy until sometime after January 1 of the tax year in question. For further assistance regarding an exemption for a newly constructed home, please contact us.

How are Homeowner Exemption savings calculated?
Your property tax savings from the Homeowner Exemption is calculated by multiplying the Homeowner Exemption savings amount ($10,000) by your local tax rate. Your local tax rate is determined by the Cook County Clerk and can be found on your second installment tax bill or by contacting the Cook County Clerk's Office at 312- 603-6566.

Please Note: The Homeowner Exemption reduces the Equalized Assessed Value (EAV) of a property by $10,000.  EAV is the partial value of a property used to calculate tax bills. It is important to note that the exemption amount is not the dollar amount by which a tax bill is lowered.

I am no longer eligible for the Homeowner Exemption, how do I opt out? 
Please complete the Exemption Waiver

How can I apply for a Homeowner Exemption for a prior tax year?
If you were eligible for the exemption in a prior Tax Year but the exemption was not on your bill, you can apply for a refund or corrected bill by filing for a certificate of error
