Grundy County Real Estate Tax Bills Press Release

June 2, 2016

The County Clerk’s office works to provide accurate tax levy data for use in determining tax rates.  Every year during the tax extension process, levy requests are entered into the Clerk’s software, including bond amounts.

However, very infrequently, errors do occur.  Fortunately, there is a system of checks and balance in place to catch and rectify such errors prior to the taxpayers’ receipt of their tax bill.  Such was the case when an error in the Clerk’s calculation of the school district’s debt service levy was discovered by Minooka School District No. 111, and reported to the Clerk’s office prior to the mailing of the tax bills.   The tax bills were scheduled, and ready for delivery on June 3rd, however, once this was discovered, the Treasurer’s office pulled the bills from being sent.  The Clerk’s office has since recalculated the levy, the District has approved the calculations, and the tax bills will be mailed on or before June 15th with the first installment due July 15thand the second installment due September 15th.
