No, you cannot appeal your property taxes to the Board of Review because you believe your taxes are too high. The Board of Review does not have the power to set property tax rates. The taxing entities (e.g., schools, libraries, park districts) that your property sits within have the ability to set property tax rates. The Board of Review may review only the assessed valuation of the property based on the information submitted by the taxpayer. The assessed valuation of a property cannot be changed once the Board of Review completes its session for the year. 

Not necessarily. Your property tax bill is the product of your property’s Equalized Assessed Value times the aggregate tax rate for the taxing entities where your property is located. The Equalized Assessed Valuation (EAV) is your property’s fair market value times .3333. So if your EAV went down, but your aggregate tax rate went up, it is entirely possible that your actual property tax bill stayed the same or increased. The Board of Review has no power to affect the aggregate tax rate for your property.
