A Message from DuPage County Treasurer/Collector: Gwen Henry

Dear Property Owners:

In Illinois, the 2020 taxes are billed and collected in calendar year 2021. The first installment of taxes is due by June 1, 2021, and the second installment is due by September 1, 2021. Taxpayers who have experienced a financial hardship due to the effects of the COVID-19 pandemic should fill out a waiver form to delay the 1st installment payment until August 1, 2021 without penalties. Last year, 1,992 property owners participated in this program. The waiver is available on the Treasurer’s website:  

As I write this letter, I understand that the average tax rate is down .62% with the average tax bill up 3.18%. Even though your tax rate may have decreased, the amount of taxes you owe can increase if the taxing bodies ask for more money. The assessed property value for DuPage County is $43,052,174,491 an increase of 3.8% in 2020. We will collect approximately $3,027,817,624.46 to distribute to the appropriate taxing bodies..

Due to the COVID-19 pandemic, the vacancies of commercial property are increasing, lowering their assessed value. As commercial property values decrease, residential property will take on a greater percentage of the tax burden. In tax year 2019, residential property made up 76.0% of the County’s value compared to 2020’s 76.3% of the County’s value. .

Please review your tax bill to ensure you are receiving all the exemptions you are entitled to receive. The most often missed is the senior exemption. If you are 65 or older, check to make sure you are utilizing this exemption. This year, seniors in DuPage County have been granted exemptions on 69,283 parcels of property resulting in a reduction of $364,415,000 in assessed value. There have been instances where taxpayers in their 80s have never benefited from this exemption.

The Treasurer’s team is ready to assist you with your questions and payments. Our website is available 24/7. It has some interesting information about your property including: Property Tax distributions, assessment information regarding your property, a five (5) year Property Tax history and a sale history on your property. You can also print a duplicate bill. We also urge you to consider using ePay for your property tax payments.

If you have questions, please feel free to contact my office at 630-407-5900 or  It is a privilege to serve you.

Gwen Henry, CPA, DuPage County Treasurer
