The annual DuPage County real estate tax bills are mailed on or about April 30th of each year. This general mailing of over 300,000 tax bills is the only mass mailing of real estate tax bills for both the 1st and 2nd installments. Unfortunately, many tax bills are returned to the Treasurer's
Office by the U.S. Post Office for a variety of reasons. If you do not receive a tax bill by the second week of May, please contact this office and a copy bill will be provided.
According to Illinois Compiled Statutes, FAILURE TO RECEIVE A BILL DOES NOT RELIEVE THE TAXPAYER OF THE PENALTY IF THE PAYMENT IS LATE. The U.S. postmark is used to determine the late penalty.
The DuPage County real estate tax bill is mailed with two installment payment coupons attached; each representing an equal installment of the real estate tax due. The first installment is due on or before June 1, 2018, and the second installment is due on or before August 31, 2018. The lower section of the tax bill shows a
comparison between this year’s taxes and the prior year’s taxes. The comparisons (by amount and by tax rate) are shown for each taxing district that receives your money. See Sample Tax Bill (when available).
This section also illustrates how your individual tax bill was computed. Please note the exemption boxes. Senior exemption information is described on the SeniorServe website. The residential
exemption is granted to owner-occupied residences. If you did not receive a residential exemption, and you believe you should have, contact your Township
Assessor. The Township Assessor’s phone number is listed on the front of your bill.

PLEASE NOTE: Only balanced transactions will be processed. Include a self addressed envelope with sufficient postage or a return airbill with your account number for the return of your receipts. We do not pay postage or carrier fees to return printed
materials. Duplicate tax bills are available online under Tax Payment Status at no charge.
Payment Under Protest
Per state statute, you may protest your tax by completing both of the following actions.
1) Pay the tax in full no later than October 31, 2018. Penalty computed at 1.5% per month must be added if payment is made after the installment due dates of June 1 or August 31, 2018.
2) File a tax objection complaint with the DuPage County Circuit Court Clerk. Forms may be obtained from the Circuit Court Clerk’s office or by calling 630-407-8700. A tax objection complaint filing fee may be imposed by the Circuit
3) Property tax is calculated multiplying the tax rate by the assessed valuation. After a review of these factors, you must determine the basis for filing an objection.
OBJECTION TO TAX RATES
The tax rate, which is determined by the DuPage County Clerk, is based on the amount levied by each of the local taxing districts. To effectively protest a tax rate,
you must prove that the tax rate or a portion of the tax rate is illegal or excessive. You may wish to seek legal advice.
OBJECTION TO ASSESSED VALUATION
The assessed valuation is based on a property’s fair cash value, which is determined by the township assessor. In order to file a tax objection based on the assessed valuation, you must have already filed an assessment complaint with the DuPage County Board of
Review 630-407-5888. You should not file a tax objection based on assessed valuation if you have already filed an appeal with the State Property Tax Appeal Board for tax year 2017.
If you believe there is an error in your assessment, you should contact your township assessor before August 31, 2018. An assessment review may reveal a computational error, which the assessor can
correct by issuing a certificate of error. This could eliminate your need to file an objection. Additionally, confirm that you are receiving all
exemptions for which you qualify, including senior, senior assessment freeze, residential, or the home improvement exemption.
Mobile Home Tax
There are approximately 300 mobile homes in DuPage County. Tax bills for the current year are mailed by August 1st of each year with a due date of October 1st. The tax amount is based on the age and square footage of the mobile home. Taxes that remain unpaid by the due date will result in a penalty of $25.00 per month with
a maximum penalty of $100.00. Failure to pay a mobile home tax will result in a lien being recorded against the owner. Title on a mobile home cannot be transferred without a tax payment certification from the County Treasurer indicating all taxes are paid. For more information please contact the Treasurer's
