Lake County Treasurer  

Welcome to the Lake County Treasurer's website 

Tax year 2014 dates are
June 3rd & September 3rd 2015

Important Notice: Those homeowners that may depend on the U.S. Postal Service to "Temporarily Forward" their bill to a second location should be aware that due to new postal regulations, your future bills may not be forwarded as they have in the past.   We ask those homeowners affected to please sign up for e-notification on our website.  Once the annual tax bills are available, a notification will be mailed.  Failure to receive a bill does not relieve the taxpayer of penalty if payment is late.

New this year: The return envelopes that accompany your tax bill will include the return address of our new PO BOX located in Bedford Park, IL. This location was selected as it is the closest Post Office to our Lock Box facility. We are very excited for this new option as we are always looking for ways to improve productivity here at the Treasurers’ office.
