Montana’s property tax system is a complicated thing, involving mind-boggling math and a bewildering array of rules aimed at fairly dividing the bill for public services like schools and police departments between hundreds of thousands of properties.It’s a tricky task, of course, to agree on what exactly fair means when it comes to taxes — and a trickier one for lawmakers to write a tax code that implements a fair framework without loopholes. Earlier this week, Montana Free Press and High Country News published a lengthy investigation into a facet of the state’s tax code that has been a perennial concern on the loophole front for decades: whether a property tax break intended for farms and ranches is being abused by people who own luxury homes on rural parcels.Our full story, which you can read here, runs more than 3,400 words. If you’re looking for something briefer, here are some of the key takeaways:1. Agricultural tax status offers farm and ranch properties a discount relative to residential properties by marking down the value of the underlying land.If you own a Montana home in an urban or suburban neighborhood, it’s almost certainly classified as a residential property. For those, both the house structure and the home lot beneath it are valued and taxed based on their market value — how much the Montana Department of Revenue thinks they would sell for.Structures on agricultural properties are also valued and taxed based on their market value, but the underlying land is not. Instead, agricultural land is valued for tax purposes based on its production value — how much money the revenue department thinks its owner could make growing crops or grazing livestock.That’s a significant difference. Home lot prices vary from place to place across Montana, but the average residential property had a land value of about $127,000 in 2023. Production values are much, much lower. Some of the properties we looked at, for example, had grazing land valued at less than $50 an acre.2. The agricultural discount can translate into hundreds or thousands of dollars in annual tax savings.One example we looked at was a property on the Flathead River near Kalispell, described in a Zillow listing as a “gorgeous Montana river estate” with a putting green and orchard. Classified as agricultural land, the 10-acre property paid about $7,000 in property taxes in 2023, all but $20 of that based on the value of the property’s structures, according to our analysis.A 10-acre residential property next door, including a slightly less valuable home, paid about $9,100 in taxes in 2023, including about $3,300 in land taxes.That sort of disparity is typical. For parcels smaller than 20 acres, we found that residential properties paid a median effective land tax of $1,609 an acre in 2023, compared to only $6.61 for agricultural parcels.3. Critics worry that it’s too easy for high-end real estate to qualify for agricultural tax benefits.Unlike most western states, larger Montana properties automatically qualify for agricultural tax treatment without being required to document that the land is being used for agriculture. Properties of 160 acres or more are automatically granted a full agricultural designation, while properties bigger than 20 acres automatically qualify for a partial agricultural designation that offers slightly reduced tax benefits regardless of whether the land is being put to significant agricultural use.Smaller properties can qualify for the full designation by reporting at least $1,500 a year in agricultural income. Critics say that threshold, which hasn’t been updated since 1986, is low enough that savvy property owners can reach it with relatively little effort.4. Thousands of million-dollar Montana homes are benefiting from the ag tax treatment. Gov. Greg Gianforte’s Bozeman home is one of them.Looking at state property data for 2023, MTFP and HCN found more than 3,000 properties with million-dollar structure values that qualify for the full or partial agricultural tax benefit. In some cases, like the Flathead River example, those properties are adjacent to otherwise comparable residential properties, resulting in stark tax disparities.Another example is Gianforte’s home on an 11-acre parcel with an agricultural designation on the outskirts of Bozeman. According to our calculations, the governor and his wife, Susan, paid about $5.75 an acre in land taxes on it in 2023 while a neighbor with a residential parcel across the street paid $826 per acre. (The governor’s office said that the Gianfortes’ property, which also includes additional parcels, is used for barley and alfalfa production and is also used to board horses and mules.)The governor’s $66 land tax bill for the 11-acre parcel is also less than what the vast majority of urban homeowners in Montana pay each year for the lots beneath their homes.5. Lawmakers could change the tax code as the Montana Legislature meets this year.As the session opened in early January, there were two bills under consideration that would tighten qualification standards for the agricultural designations (House Bill 27) and increase taxes on homesite portions of high-value ag properties (Senate Bill 4).Similar measures have floundered in the past, in part because of opposition from people who would face higher tax bills. The sponsors of both measures told MTFP this week that they are working on revisions to their proposals in an effort to make the bills politically viable.READ MORE: Montana’s agricultural tax rules slash bills for thousands of million-dollar homes.The post Key takeaways from our investigation of Montana’s agricultural tax code appeared first on Montana Free Press.
