Assessment Process

After the Board of Review has heard all complaints in the County, the finalized assessment books are delivered to the County Clerk. The County Clerk totals the equalized assessed value for each taxing body district. By this time, the County Clerk has received the levy requests from all taxing bodies within the County. The Clerk then calculates the tax rates for each combination of taxing districts. The tax rate is applied to the billing value assessment to create the tax bill.

County Treasurer

The County Treasurer prepares and mails the tax bills on or about May 1 in DuPage County. The taxpayer pays the bill in two equal installments due on June 1 and September 1. The Treasurer distributes the tax money proportionately to each taxing district as the tax money is collected. The Treasurer also prepares a delinquent tax list and sends Notice of Application of Judgment on Real Estate. After receiving judgment from the Circuit Court the Treasurer also administers the sale of lien on real estate due to nonpayment of taxes.

Tax Bill Calculation

Equalized Assessment - Exemptions = Billing Value x Tax Rate / 100 of valuation = Total Tax Bill

The DuPage County tax bill also lists all of the taxing bodies being paid. The current and prior years's taxing body's tax rates, property assessments, and the corresponding market value of the property.
