Senate Republicans Back Flat Income Tax Plan
Republican leaders in the Montana Senate will back Gov. Greg Gianforte’s push for the state to have a single, flat income tax rate during the 2027 session.
In a press release on Monday, July 13, Senate President Matt Regier, R-Kalispell, announced he officially requested a draft bill titled “Lower Montana state income tax rate” to match Gianforte’s goal for his final session as governor.
