A Senior Exemption provides property tax savings by reducing the equalized assessed value of an eligible property. Most homeowners are eligible for this exemption if they meet the requirements for the Homeowner Exemption and were 65 years of age or older during calendar year 2020. Once this 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 received the Senior Exemption on my tax bill last year. Do I have to reapply for the Senior Exemption this year?
No. Senior exemptions renew automatically, meaning you only have to apply once. If you received a Senior Exemption on the second-installment tax bill you received in July 2020, you do not have to reapply for this exemption.

I qualified for a Senior Exemption. Do I have to apply for a Homeowner Exemption separately?
No. Seniors receiving the Senior Exemption automatically qualify for the Homeowner Exemption and do not have to apply for it separately.

How are Senior Exemption savings calculated? 
A Senior Exemption is calculated by multiplying the Senior Exemption savings amount ($8,000) by your local tax rate. Your local tax rate is determined each year 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.

Are there other property tax savings available to seniors?
