Your annual property taxes are made up of levies from the individual taxing bodies that service your area. Each taxing body determines how much money is needed to operate during the coming year, and how much needs to be raised through property taxes. The amount to be raised is the levy. The levy is sent to the County Clerk where the tax rate is calculated by dividing the total amount of assessed value in the jurisdiction by the levy.
