According to the Illinois Compiled Statutes, 35 ILCS 200/15, the Lake County Collector is bound by state law to collect 1.5% penalty per month on any unpaid installment balance after the due dates.
For this year, due dates are June 5th and September 5th, therefore the penalty is calculated on the 6th of each month and is not prorated by state law.
Forgiveness of the penalty must be due to a Lake County error and must be documented.
PLEASE NOTE: Not receiving a tax bill, medical emergencies, travel or payment history do not qualify for exemption.
