Under Illinois law, unpaid property taxes in Cook County accrue statutory interest at the rate of 1.5% per month. That adds up fast. If taxes stay unpaid, the county holds a tax sale where investors pay the back taxes. The property owner then has a redemption period of 2 to 3 years to pay back the amount plus interest and penalties. All of these actions create property tax records that show up when you search a parcel in Cook County.
