DuPage Township is a WILL COUNTY office

More info can be found at www.willcountysoa.com



SENIORS:  New freeze forms will be mailed out at the beginning of April 2018. If you did not file last year or have never qualified before, please come into our office with your income tax papers after April 1, and we will be able to assist you.  Please note the maximum income amount has changed. To qualify for 2018, you must be 65 or older, lived in your home more than 2 January 1sts, and have a total household income below $65,000. You can visit our “exemption” tab to read more about this.


We are available Monday thru Friday from 9am to 4pm to assist you in filling out the freeze, or any other exemptions you may qualify for. If you would prefer to fill out your freeze with a representative from Will County, they will be available at the Levy Center from 9:30am to 12:30pm on Tuesday, May 22, 2018.



2017 TAX BILLS (payable in 2018):  Tax bills will be mailed from Will County at the beginning of May 2018.  They are due in two installments (only one bill is mailed).  Due dates are usually on June 1st and September 1st, depending on the day of week.


Please check your tax bill for any missing exemptions.  They are explained on the back of your tax bill.  If there are missing exemptions, please call or come in to our office as soon as possible to have it looked over. If you are not sure what you qualify for, please visit our “exemption” tab to see what is available.  If you see no dollar amount in the senior freeze and you applied, please look at your assessments first. If your assessment is lower than the amount you were frozen at, there will be no adjustments made in that line item.  


There are two separate factors that make up your tax bill; the tax rates and assessments. The tax rate is determined by taxing bodies in the area. They are listed on the tax bill.  If you are concerned with the rate you are paying, please contact your taxing bodies.   Please see our tab “Taxing District Info” for name and contact information.  Budgets are set in the Fall and tax payers are encouraged to attend those meetings, which set the rates you pay.


The Assessor’s Office is responsible for assessing every property.  When tax bills are mailed, it is not the time to appeal your assessment.  Assessments for this tax cycle were finalized in September 2017.  Assessments cannot be changed at this point. The new 2018 assessment notices will be mailed out in August 2018 if there is a change in the assessed value. 


 If you feel you would like your assessment reviewed further for 2018, there is a tab for our Assessment Review – follow the instructions and send the paperwork to our office by the deadline noted.  Or please call our office and we will instruct you how to proceed.  Please always note the deadlines on the notices for appealing.  You DO NOT need a lawyer, tax consultant or to pay a fee to have your assessments reviewed.  This is what we do and we are here to help you understand the process. 


As always, if you have any further questions please feel free to call our office and anyone of our staff will be able to answer your questions.
