Frequently Asked Questions

• When will the 2022 payable 2023 tax bills be mailed?
  September 22, 2023
• 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).

  According to Illinois State Statute, the County Treasurer must hold an annual tax sale to sell unpaid property taxes.

It should be noted that the longer the homeowner waits to redeem these taxes, the more the interest could be.
