Late Payment Penalty

  • According to the Illinois Compiled Statues, 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 7th and September 7th, therefore the penalty is calculated on the 8th 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.
  • Not receiving a tax bill, medical emergencies, travel or payment history do not qualify for exemption.
