Tax Bill Questions? We've Got Answers
Property tax bills have arrived. Tax bills are due for the 2014 tax year in two equal installments (June 3 and Sept. 3). Visit the Treasurer’s Office website for information on how to make a payment. 

We have a number of transparency tools to help you understand your tax bill. Get answers to some frequently asked questions​, and you can also view current and previous bills.  

Keep in mind, while you send your payment to Lake County, the County only keeps a small portion (about 7%), and the rest is distributed to many other taxing districts. Check out our new interactive Property Tax Tour to see exactly where your tax dollars go. And, visit Lake County’s budget portal​ to see what Lake County does with its portion.
