Pittsburgh’s mayor has given the city’s universities an ultimatum: Cough up five million dollars by Monday, or we’ll start taxing your students on Wednesday.

Pittburgh, which is facing a $15 million budget deficit for the coming year, is attempting to close that gap by doing something no American city has ever done before — tax college tuition. Mayor Luke Ravenstahl proposal for a one percent annual tax has drawn strong opposition from Pittsburgh’s student community, but it appears to have the support of five of the nine members of the city council.

Pittsburgh’s universities have said that they will not consider increasing their voluntary donations to the city until the tuition tax is taken off the table. The first of two council votes required to implement the tax is scheduled for this Wednesday.
