State Rep. Brendan Boyle is trying to throw a wrench in the city's plans to bring in extra dollars with a shift to a property tax system based on market values.

Boyle today introduced a bill in Harrisburg that would require that the move to the new property tax system – known as the Actual Value Initiative – be revenue neutral. Mayor Nutter plans to collect an additional $90 million in property taxes for the school district with the shift to AVI, although he says that is simply the city capturing the increase in property values.

"If you're going to go down this path, this would ensure that it must be revenue neutral. It would ensure that this reassessment isn't just a back door tax increase," Boyle said.

We've sought comment from the administration and will update when we hear back.
