Tax Extension


The Tax Extension Department of the Will County Clerk's office accepts filings of annual budgets, appropriations, levies, bonds, boundary changes and other financial reports as mandated by the Illinois Property tax code.

Tax Extension is the process by which Taxing districts file their annual budgets and levies and request the amount of money needed to operate and to be raised from taxation (property taxes).
