Georgists like to say that one of the many advantages of a real estate tax over other taxes is that, if the owner does not pay it, eventually s/he’ll lose the property, which can be sold to pay the arrears. But “eventually” is an important word here.
Now Cook County Treasurer Maria Pappas has compiled data showing the extent to which taxes don’t get paid. For this purpose, “not paid” means “not paid within a month of the due date.” I suspect that in most cases, these taxes are eventually paid, with a penalty (9% interest, recently reduced from 18%) included. But years might elapse, and various games can be payed by “investors” regarding these properties. (Some detail is on pages 23-26 of this pdf.)
The reports are broken out by property class, by ward, by municipal area, and by taxing agency, showing amount billed and amount paid, and can be downloaded to spreadsheets.
Countywide, 96% of all taxes billed were collected within a month of the deadline. In the impoverished Village of Ford Heights, only 28.55% of taxes got paid, but no other community had less than 50%. The six lowest percentages are all in the south suburbs, followed by the Chicago community areas of Englewood and West Garfield Park.
For parcels coded as “vacant,” only 71% of taxes were collected; all the other categories were above 95%. Total taxes billed to vacant parcels was $121,810,594, of which $86,873,652 was paid, implying that, were vacant parcels taxed at the same rate as commercial and industrial land, government revenue would increase by something like $130 million to $183 million — not counting the development which such a tax increase would encourage.
