Tax Extension

The levies for each local taxing body are set by its governing board. The County Clerk tax staff extends, or calculates, the tax rate (set within statutory limits by the local board for each taxing district) to each property's valuation set by the Township Assessor. Property valuations are certified to the County Clerk by the Chief County Assessment Officer.

The extension of taxes is computed according to the state statute and no adjustments may be made to assessed valuations or levy rates once the values have been certified to the Clerk. This information is sent to the County Treasurer whose office prepares and mails each tax bill.
