Tax Extension Services


The Will County Clerk's Office Tax Extension Department accepts filings of annual budgets, appropriations, levies, bonds, financial reports, and boundary changes for all local taxing districts. These filings tell the County Clerk how much money each district is requesting and what properties have to pay their share of the burden. Tax extension is the process whereby tax levy requests are divided by assessed values provided by the Will County Assessor to calculate tax rates and tax dollar extensions for each unit of government. These rates and extensions are used by the Will County Treasurer to send out and collect each tax bill. The Treasurer then distributes the collected tax money to each tax district so the tax district can provide services back to the taxpayers.

For more on property tax law see the online version of the Illinois Statutes, Chapter 35 REVENUE 200/ Property Tax Code.
