The Property Tax Code states that each property shall be assessed at 33 1/3% of “Fair Cash Value” (i.e. a fair cash value of 120,000 x .3333 of /3 = 40,000 assessed value).  Fair Cash Value is defined as; the amount for which a property can be sold in the due course of business and trade, not under duress, between a willing buyer and willing seller.  The date of valuation is January 1 of each year. Illinois law requires the assessor to update values at least once every four years.  Our goals are to determine an accurate market value estimate of property, and to assure that similar properties have similar assessments.If you own and occupy (legal residence) you may be eligible for exemptions to that property.
