What county are you actually buying into when you buy in Mountain Village?
Most buyers assume the question doesn't apply. Big Sky reads as one place, one resort, one market. But Big Sky is not a single jurisdiction. It is a community split across two counties, and the Mountain Village area, the ski-in/ski-out base area built around Lone Mountain, sits entirely on the Madison County side of that line. A few miles down the road, Meadow Village and Town Center sit entirely in Gallatin County. Same resort town, same zip code in casual conversation, two different county governments, two different school assignments, and until recently, two different answers to which hospital your property taxes actually fund.
That distinction is not trivia. It shapes what a specific Mountain Village parcel owes under Montana's new 2026 property tax rules, what district your taxes support, and how fast your assessed value has been climbing relative to the rest of Big Sky. None of it shows up on a listing sheet. It shows up in the closing documents and the first tax bill.
One resort, two counties, and Mountain Village lands on one side
Big Sky straddles the Gallatin-Madison county line, which runs roughly north-south through the Madison Range. According to Explore Big Sky's reporting on how the two counties divide the town, Big Sky Resort, Moonlight Basin, and Yellowstone Club all sit in Madison County, while Meadow Village, Town Center, and the Gallatin Canyon sit in Gallatin County. That places Mountain Village, along with its immediate neighbors on the mountain, squarely in Madison County, whose seat is Virginia City, a different county government than the one running Meadow Village three miles away, seated in Bozeman.
For a buyer comparing a condo in Mountain Village against one in Meadow Village or Town Center, that's not a stylistic difference between neighborhoods. It's a difference in which county assessor values the property, which county treasurer bills it, and which special districts it belongs to.
The school assignment on paper isn't the one in practice
Big Sky's two counties also feed two different school systems. The Gallatin County portion of Big Sky, including Meadow Village and Town Center, is zoned to the Big Sky School District. The Madison County portion, which includes Mountain Village, is zoned to the Ennis K-12 school district, seated on the other side of the Madison Range.
In practice, most Madison County families in Big Sky send their kids to Big Sky's own schools rather than driving around the mountain to Ennis. For years that mismatch meant Big Sky's district was educating students it wasn't fully funded to serve. The Montana Legislature addressed it directly in 2025 with House Bill 846, which now requires the Ennis school district to pay Big Sky's district for the roughly 25 to 26 students who live in Madison County but attend school in Big Sky. If you're buying a Mountain Village property as a full-time residence with school-age kids, it's worth knowing the zoning on paper and the arrangement in practice are two different things, and the second one is now a funded agreement rather than an informal courtesy.
The hospital tax question that just went to voters
The same county line determines which hospital district a Mountain Village property's taxes support, and that arrangement has been unsettled for years. Madison County properties in Big Sky, Mountain Village included, have paid into the Madison Valley Hospital District, which funds Madison Valley Medical Center roughly 90 road miles away in Ennis. Big Sky has its own hospital, Big Sky Medical Center, but it sits across the line in Gallatin County, so Madison County residents needing care in an emergency typically go there instead, despite their hospital tax dollars flowing to Ennis.
That mismatch reached the Montana Legislature in 2025 through Senate Bill 260, which created a path for Big Sky's Madison County taxpayers to withdraw from the Ennis-based hospital district over an eight-year step-down period rather than all at once. The resolution went before voters directly on a May 5, 2026 mail-in ballot, asking Gallatin County residents whether to form a new local hospital and wellness district and asking Madison County residents whether to withdraw from the Ennis district in favor of one. If you're closing on a Mountain Village property this year, the useful takeaway isn't the history, it's that the hospital-tax framework attached to that parcel has been actively changing within the past year, and it's worth asking your title company or the Big Sky Resort Area District for its current status before you close.
Why the county line matters more under the 2026 tax rules
Montana's property tax structure changed for 2026 bills. Primary residences and qualifying long-term rentals now get tiered rates that start low and rise gradually with value, according to the Montana Department of Revenue. Second homes and short-term rentals, the ownership profile that dominates Mountain Village, go straight to a flat 1.90% of assessed value regardless of price point.
That flat rate lands on top of a valuation trend that isn't uniform across Big Sky. At an August 2025 forum in Big Sky, the state's revenue director walked residents through assessed value changes on each side of the county line. Per Explore Big Sky's coverage of that forum, the median property value on Big Sky's Gallatin County side, covering Meadow Village, Town Center, and the Canyon, roughly tripled between 2021 and 2025, moving from about $500,000 to $1.5 million. On the Madison County side, where Mountain Village sits, the median value more than tripled over the same span, from about $1.2 million to $4 million.
Pair that steeper valuation curve with the flat 1.90% non-homestead rate and the arithmetic is straightforward: a Mountain Area second home has been appreciating faster, on average, than a comparable property down in Meadow Village, and it's being taxed at the same flat percentage regardless of how high that value climbs. If a property in Mountain Village will function as your primary residence for at least seven months of the year, it may instead qualify for the tiered homestead rate, but you have to apply. The application window for the 2027 tax year opened May 4, 2026 and runs through March 1, 2027, so if you're closing this year, that filing is worth putting on the calendar rather than assuming it happens automatically.
What to verify before you write an offer
A short verification pass before you write an offer answers most of this in one phone call:
- Confirm the county of record for the specific parcel with the title company or county assessor, not just the general Mountain Village name.
- Ask whether the property currently qualifies for the homestead or long-term rental tiered rate, or falls under the flat 1.90% non-homestead rate, and confirm whether that status carries over to a new owner or needs to be filed again.
- Confirm the school district the parcel is zoned to on paper, particularly if the home will be a full-time residence.
- Ask about the current status of the property's hospital district taxes, since that framework has been mid-transition through 2026.
- Request the most recent actual tax bill for that parcel rather than relying on a neighborhood-wide estimate.
None of this is a reason to avoid Big Sky's Mountain area. It's a reason to ask precise questions about a specific address rather than general questions about a neighborhood name, because in this case the neighborhood name covers one county government, one school arrangement, and one tax curve that looks different from the rest of Big Sky.
FAQ
Are Moonlight Basin and Yellowstone Club in the same position as Mountain Village? Yes. Both sit in Madison County alongside Mountain Village, so they share the same county-level tax, school zoning, and hospital district framework, though individual valuations vary by property.
If my kids would attend Big Sky's schools anyway, does the Ennis zoning still matter? It matters for the paperwork more than the classroom. House Bill 846 now funds the arrangement that lets Madison County students attend Big Sky's own schools, but the underlying zoning is still worth confirming when you close.
Does the May 2026 hospital district vote affect a purchase I'm closing on now? It may. Ask your title company or the Big Sky Resort Area District for the current status of the hospital district tied to your specific parcel, since the transition outlined in the 2025 legislation was still being implemented as of this writing.
Mountain Village rewards buyers who ask about a specific parcel rather than a general neighborhood. If you want a clear read on what a particular Mountain Village address actually costs to own, from the county it sits in to the tax bracket it falls under, Sandy Revisky De Leon can walk through it with you.
