SPOILER ALERT if you are watching the TV Series Yellowstone: at the start of Season 5, John Dutton (played by Kevin Costner) is sworn in as Governor of Montana. One of his first proposals in his inaugural address is that the state legislature “double property taxes for non-residents” who have been buying up vacation homes in the state, and contributing to the increase in property values in the state (a fact which drives many plotlines throughout the series). This episode aired in November 2022.
This week, the real governor of Montana signed a pair of bills which effectively did what the fictional governor John Dutton proposed: significantly increasing property taxes on non-residents. Starting in tax year 2026, the property taxes for non-primary residences (which will include non-Montana residents and Montanans who own vacation homes) will be based on 1.9% of market value, while Montana residents will pay a graduated rate structure for their primary residence: 0.76% for property up to the state median (currently about $340,000), 0.9% up to two times the state median, 1.1% for the value between 2 and 4 times the state median, and 1.9% (the same as non-residents) for the value of homes above 4 times the state median ($1.36 million currently). Currently residential property is taxed at 1.35% of market value, meaning that while the rate hasn’t fully doubled for non-residents, most non-residents will be paying twice or more in property taxes than Montana residents.
I was a non-resident member of the Montana Property Tax Task Force, and served on the “Tax Fairness” subcommittee where the plan for HB 231 originated, so I have somewhat of a unique perspective on these changes to property tax rates. I will offer a few thoughts, some of which are critical, but let me first say that it was a great honor to be asked to serve on the Task Force by Montana’s Governor. Also, everyone on the Task Force was very friendly and receptive to ideas from outsiders (I was one of three non-Montanans on the Task Force), and so my comments here are not critical of the Task Force process nor anyone on it. As I did when I served on the Task Force, my goal in this post is to try, as best as I can, to objectively analyze how this proposal (now law) will impact Montana.
