Reminder-2nd Installment of Real Estate Tax Due

August 20, 2019


DeKalb County Treasurer Christine J. Johnson would like to remind taxpayers that the second installment of real estate taxes is due Tuesday, September 3, 2019. Taxes may be paid by mail, at most county banks, online, or in person at the Treasurer’s Office in the DeKalb County Administration Building, 110 East Sycamore Street in Sycamore from 8:30 a.m. to 4:30 p.m., Monday through Friday. Please note, the Treasurer’s Office will be closed on Monday, September 2, 2019 in observance of Labor Day.

The Treasurer’s Office accepts tax payments online using Visa, Master Card, American Express, and Discover credit cards, Visa or Master Card debit cards, and E-checks. Taxpayers may also pay using credit or debit cards in person at the Treasurer’s Office. Please note that the credit card service provider charges a convenience fee for those wishing to charge their real estate taxes on a credit or debit card. Online payments may also be made by E-check, a direct debit from your account, for a nominal processing fee.

In order to pay taxes online, taxpayers should visit the DeKalb County website at and click on the box with the red text that says “Pay My Property Taxes.” From there, search for the parcel(s) you wish to pay and click “Pay Taxes” to add the parcel to your shopping cart. When you are ready to pay, go into the shopping cart and follow the prompts to complete your transaction. You will find it helpful to have your tax bill at hand when making your payment online.

Taxpayers may also pay their taxes at most banks in DeKalb County during the bank’s normal business hours, on or before the due date of the installment. Taxpayers should bring the entire tax bill to the bank and put their parcel number on their check. Banks cannot accept payments after the due date.
If you mail your payment, the stub on the bottom of your tax bill should accompany your payment. Please put your parcel number on your check to ensure proper credit. Treasurer Johnson also reminds taxpayers paying by mail that payments should be postmarked on or before the second installment due date of September 3, 2019. Treasurer Johnson also strongly recommends that you have the post office hand cancel your payment envelope at the counter.
