Second Installment Property Tax Bills - Missing Exemptions
The Lemont Township Assessor's Office encourages all residents to carefully review their Second Installment Property Tax Bills to ensure they have received all eligible exemptions. We recently received communication from many residents about exemption issues and their property tax bills.
We are actively working with the Cook County Assessor's Office to identify the source of the issue and determine the appropriate next steps for affected homeowners. As of now, residents are expected to make their second installment tax payments to the Cook County Treasurer's Office by the October 1st deadline.
If we receive additional guidance, we will advise.
If you believe your exemptions were dropped or not applied, please send an email to Deputy Assessor Diana Groselak at [email protected] by Tuesday, September 15, 2026 with the following information:
Name
Address
Property Identification Number (PIN) (If available.)
Telephone Number
Email address
Exemptions You Believe Were Dropped OR Not Applied
We will then review the information,
compile a list, and communicate with the
Cook County Assessor's Office to address these concerns.
Thank you for your understanding.
