Montana Sales Tax Guide (2026)
Montana has no statewide sales tax — only a handful of resort towns tax lodging and prepared food. For most sellers, there's nothing to collect.

Key Takeaways
Montana has no general state or local sales tax, so there is nothing to collect on most sales into the state [1]. The only exception is a local resort tax of up to 3% levied by a handful of tourist communities such as Whitefish, West Yellowstone, and Big Sky, which applies mainly to lodging, prepared food, and certain retail within those towns [1]. Because there is no general sales tax, there is no economic-nexus registration, no resale certificate, and no sales tax holiday [1]. Businesses operating inside a resort community register for that town's resort tax locally [1].

Registration or Nexus Threshold
Because Montana has no statewide sales tax, there is no statewide economic nexus and no general sales tax to register for, collect, or remit. Sellers shipping into Montana owe no Montana sales tax.
Businesses operating physically within a resort community may need to register with that town to collect its local resort tax on lodging, meals, and qualifying retail, but this applies only inside those specific jurisdictions.
Marketplace Facilitator Law
Montana has no general statewide sales tax and therefore no general marketplace-facilitator collection law for ordinary retail goods. Its marketplace-specific rules are limited to two sectors: under Senate Bill 52 and MCA § 15-68-111, short-term rental marketplaces and online hosting platforms must register with the Department of Revenue and collect, report, and remit the state's combined 8% lodging facility sales and use tax (4% sales plus 4% use) on facilitated accommodations, and third-party platforms facilitating rental-vehicle bookings must register for a seller's permit and collect and remit the state's 4% Rental Vehicle Tax. Lodging or rental-vehicle providers remain responsible for tax on bookings made outside a qualifying marketplace or platform.[4]
Filing Frequency & Deadlines
There is no statewide sales tax return in Montana. Businesses inside a resort-tax community file with that local government on its schedule, typically monthly or quarterly.
Exemptions
With no statewide sales tax, exemption questions do not apply to most Montana sales. SaaS, software, and digital products are not subject to any statewide Montana sales tax. Resort-tax communities define their own taxable categories, usually limited to lodging, prepared food, and luxury retail.
Resale & Exemption Certificates
Montana does not issue sales tax resale or exemption certificates because it has no general sales tax [1].
Penalties
There are no statewide sales tax penalties in Montana. Resort-tax communities set their own penalties and interest for late local filings.
Audits & Appeals
Local resort taxes are administered by the community, not the state Department of Revenue [1]. For state-administered taxes generally, a final department decision can be appealed to the Montana Tax Appeal Board within 30 days [3].
