Chief County Assessment Office

• The Chief County Assessment Office is the coordinating arm for all tax assessment activity for Lake County's 280,210 real estate parcels.
  
  
• Oversees the work of local township assessors and acts as a resource to these local offices, yet the township assessor has the primary responsibility for valuing property for assessment purposes.
  
  
• This office is also where the Lake County Board of Review conducts the assessment appeal process, with the CCAO staff serving as the support for the Board’s work.
  
  
•  Determines the equalization factors for each township.
  
  
•  Mails assessment notices to all taxpayers annually.
  
  
• Processes all homestead exemption applications.
  
  
• Once the Chief County Assessment Office and the Lake County Board of Review have completed their work for a given tax year, the assessment rolls are turned over to the County Clerk's Office for the calculation of the tax rates on each individual parcel.
