As noted, the Assessor's Office is not responsible for the second major component of the tax system: taxation. However, we are including a few facts about taxation and would be happy to discuss this component of the tax system in more detail with you.

Taxing Authorities

Taxing authorities include government bodies such as school districts, park districts, municipalities, library districts and the township. As taxpayers, we demand certain levels of service from these taxing bodies which are paid for through our taxes. If you are concerned about your taxes, you may wish to attend budget hearings, call or write board members, or serve as an elected official.

Tax Rate

Taxing authorities set the tax rates and levy taxes. The tax rate is calculated by dividing the amount of taxes to be raised by the total assessed value of property within the taxing authority.

  • Tax Spending divided by Total Assessed Value equals the Tax Rate Percentage

Tax Bills

Tax bills are issued by the Lake County Treasurer's Office. Taxes may be paid in two installments: the first installment due the first week of June and the second due the first week of September. The Treasurer's office can be contacted at 847-377-2323.

Your tax bill is calculated by multiplying your property's assessed value by the tax rate.

  • Assessed Value multiplied by the Tax Rate equals Your Taxes
