Ways to pay real estate and mobile home taxes
The Treasurer / Collector accepts several payment methods for real estate and mobile home taxes. Review the county’s How to Pay Real Estate & Mobile Home Taxes page before paying if you need payment-method details.
- Pay online through the county’s online payment system.
- Pay through the automated phone payment system at 1-855-544-1055.
- Pay real estate taxes at most banks in DeKalb County on or before the matching installment due date.
- Pay by mail with the proper payment stub and parcel number or mobile home number written on the check.
- Pay in person at the DeKalb County Treasurer / Collector’s Office.
For mailed payments, the county recommends mailing early and having the payment hand-canceled at the post office because local postmark timing can vary.
Mobile home tax information
Mobile home local service tax is billed in one installment. The initial bill gives the owner 60 days to pay. After that, monthly delinquent notices may add a $25 late penalty per month for four months, up to a $100 maximum late penalty.
The county also requires a current mobile home registration form for each mobile home in Illinois. A new owner who buys or moves into a mobile home has five business days to file registration with the Treasurer’s Office.
Use the county’s Mobile Home Information page for mobile home registration and payment links.
Assessment details and tax rates
The Property Tax Inquiry may include assessment, sketch, and square footage information submitted by township assessors. If those details are missing or unclear, contact the township assessor first.
For broader tax rate and levy information, DeKalb County publishes Property Tax Levies & Rates reports. These include tax computation, district values, district rates, tax code details, exemption abstracts, drainage district summaries, and tax extension information.
Email reminders for tax collection
The Treasurer’s Office offers email reminders before each installment due date. Property owners can create an Invoice Cloud account for billing emails and paperless billing or use the county’s reminder form.
Use the Tax Collection Email Reminder page if you want reminder emails from the Treasurer’s Office.
