- Once the Chief County Assessment Office and the Lake County Board of Review have completed their work for a given tax year, the assessment rolls are turned over to the County Clerk's Office for the calculation of the tax rates for each individual parcel.
After the Board of Review completes their work reviewing assessment appeals, the County Clerk's office performs a series of calculations to create the tax bill. Our tax extension department staff calculate the proportionate share of your total tax bill that each local unit of government will receive.
