2025 Assessments Now Available in Assessor's Property Search Online Database

The Kane County Supervisor of Assessments, has published all 2025 assessment changes in  Kane County Chronicle and  the Elburn Herald's September 18th editions. All properties with 2025 assessment changes for reasons other than the Annual Equalization Factor will also receive a Notice of Revised Assessment mailed by the County.

By State law, our 2025 assessments are based on the prior three years' worth of sales, that is, sales from 2022, 2023, and 2024. Based on these sales, the 2025 Annual Equalization Factor issued by Kane County for Campton Township is 1.0843  (that is, +8.43%).

The September 18th publication of all assessment changes in the Kane County Chronicle and the Elburn Herald commences the annual 30-day property assessment appeal filing period with the Kane County of Board of Review (BOR). The deadline for filing 2025 assessment appeals for Campton Township with the BOR is  October 20th, 2025.

Please note that if you have any concerns about your assessment, our Township Assessor's Office should be your first contact - the Township Assessor and his staff are happy to discuss your assessment with you, resolve any problems, and answer any questions that you might have.

Also note that all 2025 assessments are still subject to further equalization by the Kane County Board of Review and the State of Illinois Department of Revenue.
