Your tax bill may include separate property tax rates paid to everything from the county, township, city, and school district to park, fire protection, sanitary, and even mosquito abatement districts!

This high number of taxing districts is one reason Illinois ranks #2 for the highest property taxes in America – with DuPage County second in the state!

DuPage County Property Taxes | Overview & General Information

Property taxes in DuPage County, IL are assessed and collected through a complex cycle.

  • #1. Property values are assessed by the county clerk and, with the Illinois Department of Revenue, applies an equalization factor. The assessed value (taxable value) is 33% of the fair market value of the property.
  • #2. Taxing districts pass budgets and set levies or tax rates which are delivered to the county clerk. Taxing districts include counties, cities or towns, townships, school districts, park districts, and much more.
  • #3. The county clerk calculates tax rates for every combination of taxing districts in DuPage County. These combinations are tax code areas.
  • #4. The County Treasurer is the DuPage County property tax collector. They prepare and mail tax bills, collect taxes, and distribute the money to taxing districts.

The DuPage County Treasurer is Gwen Henry.

How Much Are Property Taxes in DuPage County, IL?

Illinois does not have set property tax rates. Instead, your tax bill will be based on your home’s equalized assessed value (EAV) and the rates set each year by your local taxing districts based on their budget.

The average DuPage tax rate for the 2020 tax season was 7.3825. The average EAV for 2020 was $103,380 for an average property tax bill of $7,632.03.

Glendale Heights had the highest average property tax rate of 9.9167 in 2020 but an average tax bill of $5,548.67. In Bartlett, the average property tax rate of 9.0406 resulted in an average bill of $7,868.94 due to higher assessed values.

How Are DuPage County Property Taxes Calculated?

Here is how to calculate DuPage County property taxes.

  1. Multiply the property’s fair market value by the assessed rate of 33% to get an assessed value.
  2. The assessed value is multiplied by the State Equalization Factor to make sure tax assessments are “equalized”. If average sales prices were higher or lower than 33% of assessed values, the previous value will be adjusted. This factor is usually 1. This gives you your Equalized Assessed Value (EAV).
  3. If you qualify for an exemption, it is subtracted from your EAV.
  4. Your adjusted EAV is multiplied by the aggregate property tax rate and divided by 100 to give you your total property taxes.

The median home price in DuPage County is $335,000. The assessed value will be $110,550 assuming it does not need to be equalized. The standard homestead exemption is $6,000 which reduces the assessed value to $104,550.

The average DuPage tax rate for the 2020 tax season was 7.3825. This gives you a property tax of $7,718.40 ($104,550 x 7.3825 / 100).

Your aggregate tax rate is determined by your tax code. In Naperville, for instance, there are eight tax codes. School taxing districts vary and not all tax codes are assessed the Naperville city, parks district, or library district tax. Tax rates ranged from 5.7638 to 6.8643.

With an assessed value of $104,550 (example above), your property taxes in Naperville would range from $6,026.05 to $7,176.63 depending on the location in the city.

Taxing Districts & Your DuPage Property Tax Bill

Most people in the U.S. pay taxes to one or two local government bodies: county and city/town/village governments. There may be a separate property tax for the school district and sometimes special assessments or districts. However, the county and city use funds to pay for community services and amenities like roads, parks, and libraries.

In Illinois, it works very differently. You likely have three local government taxing districts: county, city or village, and township plus up to one dozen or more special taxing districts that may include transportation, schools, parks, libraries, fire protection, pension funds, and even mosquito abatement.

Below, you can see a sample DuPage County property tax bill for Wheaton, IL in Wayne township. There are 23 separate taxing districts with 23 different property tax rates!

Special Service Area Taxes – Another Part of Your Property Tax Bill!

Under Illinois law, a “Special Service Area” can be created within a county, city, or village in which special services or major physical improvements are provided. An SSA can be created to finance these improvements or services without levying a tax on the entire municipality or incurring debt.

An SSA tax is a 10- to 20-year bond tied to properties within the Special Service Area to pay for the service or improvement. The bond is paid off with the SSA tax rate that’s based on the assessed value of your property. The SSA assessment may range from $200 to $3,000 per year. The tax rate will depend on:

  • The size of the bond
  • The assessed valuation of properties in the SSA
  • The interest rate
  • The length of the bond

For instance, the DuPage County SSA #34 had a rate of 0.8408 in 2019. This SSA was formed for the Hobson Valley Water System Improvement Project near Woodridge, IL. The bond was issued in 2009 for $1.88 million with an interest rate of 3.0% to 4.75%.

Once the tax is levied, it is set for a specific amount of time and remains with the property.

If you are buying a home in Illinois, make sure you check the property’s tax history! You can see the SSA assessment on the property tax bill. You will be able to see how much longer the tax is levied.

What Happens if You Don’t Pay Your Property Taxes? | DuPage Property Tax Liens & Late Penalties

Property taxes are due in June and September for the previous tax year. The day after each installment is due, interest is charged at 1-1/2% per month on the delinquent balance. If you do not pay your taxes, the overdue tax amount becomes a lien on your property.

During the annual tax sale, property taxes for the previous tax year are offered for sale. If taxes are delinquent for three or more years, the debt can be offered through a scavenger sale. At least 15 days before the sale, the property owner must receive a mailed notice.

When someone buys the delinquent tax debt, they do not purchase the title to the home and instead receive a certificate of purchase representing the lien.

You have up to the day immediately before the sale to pay all delinquent taxes and other costs to stop the sale. After the sale, the property owner has up to 2.5 years to redeem the property and keep the home. If the home isn’t redeemed, the purchaser can receive the title or deed to the home.
