Governor Launches “Flat. Fair. Montana” Tax Reform Plan

He's discussed it for the past year, and now Governor Greg Gianforte is officially launching a push to move Montana to a single flat income tax rate of 4.7 percent.

At a state capitol press conference yesterday, Gianforte teamed up with the Mountain States Policy Center to announce the "Flat. Fair. Montana." campaign ahead of the 2027 legislative session.

The governor argues that despite recent tax cuts, Montana's tax bill is still too high.

"Despite our conservative reforms, however, Montana still has one of the highest income tax rates in the region. And that's just wrong." -Governor Greg Gianforte

Backers see economic boost

Policy center leaders point to an economic study showing a flat rate could add over 500 million dollars to the state's economy and boost after-tax income by roughly 650 dollars per taxpayer.

And the Governor agrees

"More businesses would choose to invest and start their business year if we can fix our tax climate. That means even more jobs, more opportunity, and more prosperity for Montana families. That has got to remain our top priority," Gianforte stressed.

He believes that will have a long-term effect on Montana families and future jobs.

"So we can invest in a future of our kids and grandkids so they don't have to leave Montana to find greater opportunity. And that's why, in this next legislative session, our administration will propose a flat fair tax for Montana."
