Cook County’s property tax system is confusing enough when people pay on time, but when they don’t, there’s a whole new level of bewilderment.
Properties with back taxes go into a knot of tax sales in which investors pay what’s due and then try — or maybe not — to collect the back taxes with interest from the owner. It’s a system for collecting tax revenue owed to local governments, but research has shown it doesn’t do a good job. Nor does it help with what should be a secondary goal of getting problem homes into responsible hands so they are no longer a blight.
