 It's up to the town to decide how much to tax. Well, of course, Senator, the towns have their own mill rate. Republicans argue the change is effectively a tax increase, with Senator Ryan Fazio, Republican Greenwich, on this show yesterday, saying that he thinks leaving the number at 80% shows the state is moving in the right direction. But they're not leaving it at 80%. They're changing it to start on the high end at 85%.
