Lake County property taxpayers receive their tax bill from the Lake County Treasurer in May with due dates in June and September. 


What happens if i don't pay my property taxes in time?

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. 

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.
