​​​​​​​​​​​​​Assessment Complaints

The final filing deadline for the 2024 (payable 2025) taxable year has passed for all Kane County Townships, and the Board of Review is prohibited by Illinois law from accepting further assessment complaints for this taxable year.  35 ILCS 200/16-75.

Assessment complaints for the 2025 (payable 2026) taxable year can be filed after the 2025 assessment notice is published in a local newspaper.  In the meantime, any questions about your property's valuation can be addressed to the Assessor of the Township in which the property is located.  Click here to see a list of Township Assessor contact information.
