Big Sky, MT Tourism Data: The Resort Tax Is a Real Number

Read this piece alongside the market report elsewhere in this cluster, which relies on entirely different, vendor-sourced revenue figures rather than the tax and visitation data covered here.

Big Sky's primary tourism-data source is the Big Sky Resort Area District, BSRAD, a special-purpose local-government district that has levied a resort tax inside the Big Sky Resort Area boundary since 1992, raised from an original 3% to 4% effective July 1, 2020. BSRAD's audited fiscal year 2025 collections figure is $23,135,037, up 11% year over year. A separate, unaudited monthly collections report from the same period shows $23,271,267. Those two figures don't match each other exactly, and this piece isn't going to average them into one number; both are presented here, labeled by source, so you can decide which is more appropriate for your own citation needs.

This piece exists to give a Big Sky host three genuinely different tourism-data lines, kept on separate lines rather than blended into one "tourism number," because they measure three different things: resort-area tax collections, Yellowstone National Park visitation, and Gallatin County-wide visitor spending. None of these substitutes for another, and none of them is an occupancy figure for short-term rentals specifically, a distinction worth stating directly before the data itself.

This piece is written for a host who wants to cite real, accurate tourism context, whether in a listing description, a guest-facing page, or a conversation about the local economy, without accidentally blending three different measurements into a single misleading number. The discipline here is simple to describe and easy to skip under deadline pressure: know exactly what each figure measures, know its source, and never let one substitute for another just because they're all broadly "tourism-related." This is not legal advice.

BSRAD's Collections: Two Figures, One Source, Neither Averaged

BSRAD's audited fiscal year 2025 collections total is $23,135,037, representing an 11% increase over the prior year. A separate, unaudited monthly collections report covering the same period shows $23,271,267. The gap between the two, roughly $136,000, is small relative to the total but real, and it's worth citing the audited figure as the primary number when precision matters, while noting the unaudited monthly figure exists as a secondary, less finalized data point. Don't average the two into a single number; that blended figure wouldn't match either BSRAD's own audit or its own monthly report.

Within fiscal year 2025, BSRAD's monthly collections peaked in March at $4,125,806 and bottomed out in November at $574,165, a swing covered in more depth in this cluster's shoulder-season report, where it serves as a secondary signal alongside AirROI's occupancy data. Here, the point is narrower: this is a tax-collections figure, reflecting the 4% resort tax applied across eligible transactions in BSRAD's boundary, not a short-term rental occupancy or revenue figure specifically. Lodging, retail, and services inside the boundary all contribute to this total.

It's worth flagging directly that this research found a specific caution around any future-year figure: a July-only vintage for fiscal year 2026 data would represent a single month, not a full-year total, and citing it as if it were a comparable annual figure to the $23,135,037 FY25 audited total would meaningfully overstate or understate the actual year-over-year comparison depending on how it's framed. Confirm the reporting period explicitly any time you cite a BSRAD figure going forward, and check the publication date on any collections report you're referencing before treating it as current.

There's also a real question, unresolved as of this research, about how BSRAD's collections split between the Gallatin County and Madison County sides of the resort area. One reading of the available materials suggests roughly a 54/46 split favoring Gallatin; another suggests something closer to 47/53. This research can't resolve which is currently accurate, and rather than pick one to present as settled, this piece flags the discrepancy directly. If a Gallatin-versus-Madison split matters to your specific claim, confirm the current figure directly with BSRAD rather than relying on either number found during this pass.

Park Visits and County Spending: Real Numbers, Wrong Question

Yellowstone National Park recorded 4,762,988 recreational visits in 2025. That's a real, well-documented figure, and it's tempting to treat a busy Yellowstone year as a proxy for a busy Big Sky short-term rental year, given the park's West Entrance proximity covered elsewhere in this cluster. Resist that temptation directly: this is a park-level visitation figure, not a Big Sky occupancy or lodging figure, and this cluster's own vendor data actually points toward Big Sky's demand pattern being winter-led rather than tied to summer park traffic, a genuine tension worth naming rather than smoothing over.

Separately, Gallatin County's own ITRR, Institute for Tourism and Recreation Research, figure shows $887.3 million in visitor spending. That's a county-wide figure, covering all of Gallatin County's tourism economy, not a Big Sky-specific or short-term-rental-specific number. Big Sky sits inside Gallatin County but represents only a portion of that county-wide spending total, and this research did not find a reliable Big Sky-specific breakout of that figure. Cite it as county context, not as a Big Sky number.

This research also found a Madison County all-visitor ITRR figure during its pass, but it isn't included here because this research couldn't confirm it to the same standard as the Gallatin County figure. Rather than publish a number this pass can't stand behind, this piece leaves it out entirely and flags the gap directly: a Madison County-side visitor spending figure remains unconfirmed as of this research, and any figure circulating for it should be treated with the same caution as the podcast figure covered next, until it can be traced to a primary, citable source.

A Figure Worth Naming Only to Rule Out

During this research, a $25 million figure attributed to an Explore Big Sky podcast appearance surfaced in passing. This piece is naming it here only to rule it out: it isn't sourced to BSRAD's own audited or unaudited collections reporting, and this research can't verify its methodology or what exactly it's measuring. Don't cite this figure in place of BSRAD's own $23,135,037 audited total; if it shows up in a pitch deck or a secondhand summary, ask directly what it's actually measuring and where it originated before treating it as equivalent to BSRAD's own reporting.

The broader lesson here applies beyond this one figure: tourism data for a market this size circulates through podcasts, secondhand blog posts, and informal summaries as often as it does through primary sources, and each step away from the primary source is a chance for a number to get rounded, misattributed, or blended with something else. When precision matters, go back to BSRAD's own published collections reports rather than a number that's been repeated a few times removed from the source, and don't let a confident, round figure substitute for one you can actually trace.

Building an Honest Tourism-Data Line for Your Own Marketing

If you're citing tourism data in your own marketing, a guest-facing page, or a pitch to a potential guest about why Big Sky is worth visiting, keep these three lines separate and correctly labeled: BSRAD's audited FY25 resort-tax collections of $23,135,037, up 11% year over year, as the primary Big Sky-specific tourism-economy indicator; Yellowstone National Park's 2025 visitation of 4,762,988 as a separate, park-level statistic relevant mainly to guests planning a park visit from a Big Sky base; and Gallatin County's $887.3 million ITRR visitor spending figure as broader county context, not a Big Sky-specific number.

None of these three should be cited as if it answers what your own short-term rental will earn; that's a separate question this cluster's market report addresses using AirROI, AirDNA, and Rabbu's vendor-specific data, not tourism-tax or park-visitation figures. Tourism data tells you about the broader area's economic activity and visitor volume; it doesn't translate directly into your own listing's occupancy or revenue without the property-specific, vendor-sourced figures covered elsewhere in this cluster, and conflating the two is one of the more common mistakes in market-report writing generally.

Keeping these lines separate isn't just a citation-hygiene exercise; it's what lets a reader, whether a guest, a lender, or another host, trust the specific number you're using for the specific claim you're making, rather than wondering whether a big, impressive-sounding figure has been borrowed from a different context to make your own pitch sound stronger than it actually is.

Why This Cluster Leans on BSRAD Over Other Sources

BSRAD is the closest thing Big Sky has to a CVB, DMO, or county-level tourism-tax authority, the kind of source this site's standing research standard calls for whenever a market's own tourism-tax data is available. It's a special-purpose local-government district specifically tied to the Big Sky Resort Area boundary, which makes its collections data more geographically precise to Big Sky than a county-wide or state-wide figure could be. That's why this piece treats BSRAD's audited collections as the primary tourism-economy indicator for this cluster, rather than defaulting to a broader Montana or Gallatin County statistic that happens to be easier to find.

That said, BSRAD's own reporting still requires the same source discipline as any other data set in this cluster. The gap between its audited and unaudited figures, small as it is in percentage terms, is a reminder that even a market's own dedicated tourism-tax authority can publish two slightly different numbers for the same period depending on where in its own reporting cycle a given document sits. Treat the audited figure as more authoritative, and note the unaudited monthly figure as a secondary, less finalized data point rather than a competing truth.

The Secondary Sources This Piece Doesn't Lead With

The Big Sky Chamber of Commerce and Visit Big Sky maintain a membership base of over 485 member businesses and a published events calendar. Those are useful, real indicators of local business activity, and this cluster's visitors-guide report leans on the events calendar specifically for guest-facing content. But membership counts and event calendars measure business activity and community engagement, not visitor spending or tax collections, and they shouldn't be cited as a stand-in for either BSRAD's collections figures or the ITRR spending data covered above, however useful they are for their own specific purpose.

At the state level, Montana recorded 13.787 million visitors and $5.0 billion in visitor spending in 2024. That's a real, useful figure for understanding Montana's overall tourism scale, but it's a state-wide number, several layers removed from Big Sky specifically, sitting above even the Gallatin County figure in terms of geographic breadth. Cite it only as broad state context, clearly labeled as such, never as a stand-in for a Big Sky or even a Gallatin County number, no matter how tempting the larger figure might be for a headline.

Laid out together, the geographic hierarchy here runs from broadest to narrowest: Montana state-wide visitor spending, Gallatin County ITRR spending, Yellowstone National Park visitation as its own separate park-level measure, and BSRAD's Big Sky Resort Area-specific resort-tax collections as the most geographically precise figure available. Citing the right level for the right claim is the whole discipline this piece is built around, and it's worth keeping this hierarchy in mind every time a new tourism figure crosses your desk.

The County-Level Figure, Named and Then Set Aside

One more number belongs in the same file this piece has already built for park visits: Gallatin County's ITRR visitor spending figure, $887.3 million. Like the Yellowstone park-visit count already discussed, this is a real, sourced number, and it's the wrong scale for describing what's happening at the level of an individual Big Sky listing. It measures spending across an entire county, not the resort area specifically, and it shouldn't be cited as though it quantifies Big Sky's own tourism economy.

Naming this figure and immediately setting it aside is more useful than pretending it doesn't exist. If a guest, a lender, or a marketing partner ever raises a county-wide spending statistic as evidence about Big Sky specifically, you're better positioned having already seen the number and understood why it doesn't answer the question being asked, than encountering it for the first time and having to work out the scale mismatch on the spot.

The BSRAD collections figures already covered in this piece remain the most directly relevant tourism-economy data for Big Sky specifically, precisely because they're collected at the resort-area level rather than the county level. Lead with those, and treat the county and park-level figures as context that answers a different, broader question.

Frequently Asked Questions

What is BSRAD's total resort-tax collection for fiscal year 2025?

BSRAD's audited FY25 figure is $23,135,037, up 11% year over year. A separate unaudited monthly collections report for the same period shows $23,271,267. Both are presented here rather than averaged, since they come from different reporting processes and shouldn't be blended into a single figure. Treat this as a starting point for your own research, not a final answer on its own.

Does Yellowstone National Park's visitor count tell me how busy Big Sky's rental market will be?

No. Yellowstone recorded 4,762,988 recreational visits in 2025, but that's a park-level statistic, not a Big Sky occupancy figure. This cluster's own vendor data actually suggests Big Sky's short-term rental demand is winter-led rather than tied to summer park traffic, which makes this distinction especially important here. When in doubt, confirm directly with the source rather than relying on a secondhand summary.

What does Gallatin County's $887.3 million ITRR figure actually measure?

County-wide visitor spending across all of Gallatin County, not a Big Sky-specific figure. Big Sky is part of Gallatin County but represents only a portion of that total, and this research didn't find a reliable Big Sky-specific breakout, so cite this figure as county context rather than a town-level number. This detail is worth revisiting each season, since local conditions and figures can shift.

Which month had the highest BSRAD tax collections in fiscal year 2025?

March, at $4,125,806. November was the lowest, at $574,165. That pattern is covered in more depth in this cluster's shoulder-season report, where it serves as a secondary signal alongside AirROI's own occupancy data for the same period. The two data sets, tax collections and short-term rental occupancy, point in the same general direction even though they measure different things entirely.

Is there a reliable visitor spending figure specific to the Madison County side of Big Sky?

This research found a Madison County all-visitor ITRR figure but couldn't confirm it to the same standard as the Gallatin County number, so it isn't included in this piece. Treat that as an open data gap rather than assuming a figure that hasn't been verified. A quick follow-up call to the relevant office is worth the time here before you commit.

Should I cite the $25 million Explore Big Sky podcast figure in my own marketing?

This research recommends against it. That figure isn't sourced to BSRAD's own audited or unaudited collections reporting, and its methodology couldn't be verified during this pass. Use BSRAD's own published $23,135,037 audited FY25 total instead when precision matters, and treat any secondhand figure repeated from a podcast or informal source with real skepticism until you can trace it back.

Why shouldn't I average BSRAD's audited and unaudited collections figures together?

Because they come from different reporting processes at different stages of finalization, and averaging them would produce a number neither BSRAD's audit nor its monthly report actually shows. Cite the audited figure as primary and note the unaudited figure separately if you need to reference both. Your own property's specifics may shift this answer, so verify before you act on it.

Does BSRAD's resort tax apply only to short-term rentals?

No. It applies across eligible transactions within BSRAD's boundary, including lodging, retail, and services broadly, not short-term rentals exclusively. That's part of why this figure shouldn't be read as a short-term rental occupancy or revenue proxy on its own, even though its seasonal shape happens to roughly track AirROI's own occupancy pattern for the same year.

Can I use this piece's tourism figures to estimate my own rental's revenue?

No. Tourism-tax and visitation data describe the broader area's economic activity, not your specific property's performance. For revenue estimates, use the vendor-specific figures, AirROI, AirDNA, and Rabbu, covered in this cluster's market report instead, and treat this piece's tax and visitor figures strictly as background context for your marketing rather than a revenue input. This is exactly the kind of detail that's easy to get wrong from a secondhand source.

What should I watch for if I see a Big Sky tourism figure for fiscal year 2026?

Confirm the reporting period explicitly. A single month's collections figure, such as a July-only vintage, isn't comparable to a full fiscal year total like FY25's $23,135,037, and citing one as if it were the other would meaningfully misstate the actual year-over-year picture. Keep this figure separate from any other town's numbers you come across elsewhere.
