What is the tax rate for property taxes?

There is no set rate for property tax in Illinois. Your tax bill is based on two factors, the equalized assessed value (EAV) of your property, and the amount of money your local taxing districts need to operate during the coming year.

  • Most property is assessed at 33 1/3 percent of its fair market value. 
  • Farmland is assessed based on its ability to produce income (its agricultural economic value). A farm building is assessed at one-third of the value that it contributes to the farm’s productivity. ( Farm home sites and farm dwellings are assessed at one-third of their market value.)
  • Cook County uses a different system that assigns assessment levels to different classes of property. Assessment levels range from 10 percent of market value for residential property to 25 percent of market value for commercial property.
  • Other specific types of properties may qualify for a preferential assessment as permitted by law.
