Big Rock Township Assessor

A message from your Assessor

Welcome to the Big Rock Township Assessor's web page. We have developed this page as a service to Big Rock Township Residents. We hope that it provides quick and convenient access to Big Rock Township assessment information.

You will also find information about the Illinois property tax system and exemptions that are available to homeowners and special exemptions for senior citizens. I hope that you find this web site useful.
