Montana Lodging Tax for Short-Term Rental Investors: Resort Tax, State Tax, and What Platforms Don't File

Most short-term rental investors in Montana assume that if they are using Airbnb or Vrbo, their tax obligations are handled. For state-level lodging taxes, that assumption is largely correct. For local resort taxes, it is wrong — and the penalty for that assumption lands entirely on you.

Montana's STR tax structure has two tiers. Understanding which layer the platform handles and which layer you handle is the difference between compliance and a tax liability you did not know you were accumulating.

Montana State Lodging Tax

All short-term rentals in Montana — stays under 30 consecutive days — are subject to a combined state lodging tax rate of 7% to 8%. This figure comprises two components: the 4% Montana Lodging Facility Use Tax and the 4% Lodging Sales Tax.

Major booking platforms — Airbnb and Vrbo — do collect and remit these state-level taxes automatically on your behalf. As of current platform tax agreements with the state, you do not need to separately register for or remit the state lodging component if you are listing exclusively through these platforms. Verify this annually, as platform tax collection agreements change.

If you operate any direct bookings — through your own website, a direct reservation from a repeat guest, or any channel not covered by a platform tax agreement — you are responsible for collecting and remitting the full state lodging tax on those transactions yourself. That requires registering with the Montana Department of Revenue as a lodging facility.

Whitefish Resort Tax: 3%, Manually Filed, Extended Through 2045

Whitefish operates a 3% local resort tax on gross rental receipts from all short-term lodging within city limits. This tax was extended by Whitefish voters through January 31, 2045.

Airbnb and Vrbo do not collect this tax. The platforms collect and remit the state lodging component. The local Whitefish resort tax is entirely your responsibility to register for, collect, and remit.

Property owners must register independently with the City of Whitefish and file monthly returns, with remittance due by the 20th of the following month. The annual Short-Term Rental Permit ($400 fee) and City of Whitefish Business Registration are also required for legal STR operation — but even those do not create an automatic mechanism for resort tax collection. That administrative burden sits with you.

For Whitefish STR operators, the compliance stack is:

1. Annual STR Permit ($400)
2. City Business Registration
3. Annual fire safety inspection (pass required)
4. Montana Public Accommodations License through Flathead City-County Health Department
5. Monthly Whitefish Resort Tax filing and remittance (3% of gross receipts)

Missing monthly resort tax filings accumulates liability quickly. At 3% of gross receipts on a property generating $6,000 per month in gross rental revenue, you are accumulating $180 per month in local tax liability if you are not filing. A year of non-compliance is $2,160 in tax owed, plus any penalties and interest the city applies.

Big Sky Resort Area District Tax: 4%

Big Sky operates under the Big Sky Resort Area District Tax — a 4% tax assessed on all lodging agreements under 30 days. This is separate from both state lodging taxes and any Gallatin County or Madison County local taxes.

Like the Whitefish resort tax, this local tax is not collected by Airbnb or Vrbo. Operators must independently register with the Big Sky Resort Area District and remit quarterly (or more frequently, depending on revenue volume).

Adding the Big Sky resort area tax to the state lodging rate produces a combined effective tax rate of 11% to 12% on gross rental revenue for stays under 30 days. For properties in Big Sky's high-cost bracket — entry prices regularly exceed $1.5 million for basic condos — this tax stack affects yield analysis materially.

The 2026 Property Tax on STRs: An Additional Layer

Beyond lodging taxes, Montana's 2026 property tax overhaul imposes a flat 1.90% property tax rate on short-term rental properties — defined as residential properties used for stays under 28 days. This rate is a significant increase from the baseline residential rate and is designed specifically to differentiate STR operators from long-term landlords.

The flat 1.90% rate applies to the property's assessed market value, not to rental revenue. At Montana's elevated property values in resort markets, this translates to a substantial fixed annual cost that does not fluctuate with occupancy.

Properties that transition to long-term rental status — 28 or more consecutive days for at least seven months per year — qualify for the lower tiered rate structure. Operators evaluating the STR-to-long-term rental conversion should model both the tax differential and the revenue differential against each other before making that decision.

Compliance Checklist for Montana STR Investors

Direct bookings, vacation rental management company bookings outside platform agreements, and any channel not covered by a platform remittance agreement require owner-filed state tax returns.

Why STR Investors in Bozeman Face a Different Problem Entirely

Bozeman does not have a local resort tax. What it has is a complete ban on new non-owner-occupied (Type 3) short-term rentals, enacted by the city commission on October 18, 2023. Approximately 100 grandfathered legacy permits exist and are non-transferable — if the property sells, the STR permit terminates with it.

New STR activity in Bozeman is limited to owner-occupied arrangements: spare rooms rented while the host is present (Type 1) or the entire primary residence rented while the host is temporarily away, with the owner required to reside in the home for at least 70% of the calendar year (Type 2A). Operating an unregistered STR in Bozeman is a misdemeanor subject to criminal fines and civil penalties.

For investors evaluating Montana's resort markets with STR strategies in mind, Whitefish and Big Sky remain viable — with the permit requirements and tax filing obligations outlined above — while Bozeman is functionally closed to new investment STR operators.

The Montana Investment Property Guide covers the full STR regulatory framework across every major Montana market, including the 2026 property tax implications for short-term rental classification and the compliance requirements for resort tax registration and filing.
