Treasurer Frequently Asked Questions
My mortgage company pays my taxes. Why did I get a bill?
A bill is mailed to you for your records.  A tax bill is often requested to prove residency.  Many mortgage companies pay electronically and do not require a bill. We suggest that you contact your mortgage company to confirm this.
As the new property owner, I did not live here in 2022.  Why did I receive a 2022 tax bill?

The tax remains with the property regardless of ownership. To determine your liability for paying the tax, check your closing statement to see if the seller gave you credit, or contact your attorney.

How do I change the mailing name and/or address on my tax bill?

To change the mailing name and/or address on your tax bill, contact the DuPage County Treasurer's office at 630-407-5900.

My tax bill seems too high. How can I make sure it is correct?
We suggest that you call your Township Assessor to verify that you are receiving the exemptions for which you qualify. They can also answer any questions pertaining to your assessed valuation. If you have questions about the rate charged by a specific taxing body, we suggest that you contact that taxing body.
I did not pay my taxes last year.  Where can I find out how much I owe?

Call the DuPage County Clerk's office at 630-407-5500, and ask for an Estimate of Redemption. Make sure to have your property index number (also known as parcel number or PIN number) available.

I don't know my property index number (also known as parcel number or PIN number), how can I get it?
Your Township Assessor can look up a parcel number by property address.
May I prepay my taxes?

Yes, DuPage County is now able to accept prepayment of property taxes. Contact the Treasurer's Office at 630-407-5900 and ask to speak with the collection department for additional details.  Prepayment information will not be available online.

I own multiple parcels in DuPage County.  May I pay with one check?
Yes, you may.  Please make sure that your math is correct and include a list the parcel numbers of the properties you are paying on your check.  Include the correct installment coupon(s) for each payment you are submitting.
Does a late tax payment affect my credit rating?
No, this office does not report late tax payments to any credit bureau.
If I pay by mail, how can I get a receipt?

Your canceled check is your receipt. If you should need an official document, please either call our Tax Information Department at 630-407-5900 or enclose a note requesting a receipt.  Please allow two weeks for a receipt to be issued.

Is there a charge for a copy of my bill?
No, we do not charge for duplicate copies of tax bills for the property owners.
What is the Residential Homestead Exemption?
The Residential Homestead Exemption, also called Homestead Exemption, reduces the assessed value of your property by $6,000. In order to qualify, the property must be owner occupied as of January 1st of the tax year. Contact your Township Assessor’s Office for more information. The phone number is on your tax bill, or click on the Township Assessor link on this document.
