Frequently Asked Questions
When will the 2017 payable 2018 tax bills be mailed?
The 2017 tax bills will be mailed approximately June 4, 2018, with due dates of July 13th and September 13th.
I have applied for and thought that I received the Senior Freeze exemption; how could my tax bill go up?
The Senior Freeze exemption does freeze the assessment, but it does not freeze the tax rates. In most cases this year, tax rates have increased. The taxing districts can continue to ask for more money and if the rate goes up then your tax bill will go up. But you have to remember that over the years; because of this exemption you have saved hundreds if not thousands of dollars each year.
Home values have been declining, so why is my bill higher?
There are several factors that could make your tax bill increase: an increase in the property equalized assessed value, an increase in tax rates, which come from the individual taxing districts, and new referendums approved by voters.
My tax bill seems too high. Is it too late to appeal?
Basically yes, appeals should be filed within 30 days from the date of Assessment Roll Publication. The only exception would be incorrect data that the assessment was calculated on (example would be incorrect square footage).
My mortgage company pays my taxes. Why did I get a bill?
Many mortgage companies pay electronically, and do not require a bill. We suggest that you contact your mortgage company to confirm this. A bill is mailed to you for your records.
I did not live here in 2017. Why did I receive a 2017 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.
I did not pay my taxes last year. Where can I find out how much I owe?
Call the Williamson County Clerk at 618-998-2110 and ask for an Estimate of Redemption. Make sure you have your parcel number.
I own multiple parcels in Williamson County. Can I pay with one check?
Yes you can. Please make sure that your math is correct. List the parcel numbers of the properties you are paying on your check. Include the correct coupon(s) for each payment you are making.
What are the hours for the Treasurer’s office?
Monday – Friday 8:00am – 4:00pm. Additional hours: 8:00am -6:00pm on July 13 and Sept 13 ONLY.
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 enclose a short note requesting a receipt or call us at 618-998-2142. Please allow 1 week for a receipt to be issued.
How do I pay my tax bill?
You can pay by mail, in person and at most Williamson County banks. Also, online.
Can I use my credit card for payment?
Online, you can use Visa, Mastercard, American Express and Discover credit cards. Please be aware that a convenience fee will be charged by your credit card company.
If I pay by mail do you honor postmark?
Yes, only before or on the due date, and it must be an official U.S. postmark.
What if, for some reason, I have to pay my taxes late?
You will be assessed a penalty at 1 ½% per month. After October 3rd, a $10 fee PER PARCEL will be added in addition to the 1 1/2% per month late fee.
What if, for some reason, I am altogether unable to pay my taxes? Will I lose my property?
According to Illinois State Statute, the County Treasurer must hold an annual tax sale to sell unpaid property taxes. Please remember that the county is not selling the property at the sale, but rather, the unpaid taxes. The homeowner has at least two years to pay the redemption. It should be noted that the longer the homeowner waits to redeem these taxes, the more the interest could be.
