Sales Tax on Cleaning Services in Montana (2025)

Montana belongs to a small club of states, alongside Alaska, Delaware, New Hampshire, and Oregon, that impose no general statewide sales tax at all. For a cleaning business operating anywhere from Billings to Missoula to Kalispell, this means the question of whether janitorial or maid services are "taxable" doesn't really apply, because Montana has never built a sales tax framework, retail or service-based, to apply it under.

Why Montana never adopted a general sales tax

Montana's constitution and statutes have never established a broad-based sales tax, a policy choice with deep political roots in the state, where sales tax proposals have been put to voters multiple times over the decades and consistently rejected. Instead, Montana funds state government primarily through individual income tax and, notably, taxes on natural resource extraction (oil, gas, coal, and mining royalties) that play an outsized role given the state's economy. The Montana Department of Revenue administers income tax, property tax oversight, and a handful of narrow, industry-specific taxes, such as a lodging facility use tax and a rental vehicle sales tax, but nothing resembling a general retail or service sales tax.

Because there's no general sales tax framework, there is also no dedicated statute addressing whether cleaning services are taxable, the way Nebraska's DOR Information Guide 6-401 or Florida's Rule 12A-1.0091 do. The absence of the framework is itself the answer: nothing about a cleaning transaction in Montana triggers a state sales tax obligation.

The resort tax: what the statute actually says

The one local tax that operators in Montana ask about is the resort tax, and the statute answers the question more cleanly than most people expect. Montana authorizes designated resort communities and resort areas to levy a local tax under MCA 7-6-1501 through 7-6-1509. A resort community must be an incorporated municipality with fewer than 5,500 residents that draws more than half its employment-related economic activity from businesses serving travelers, and must be designated as such by the Department of Commerce. A resort area is the unincorporated equivalent, capped at 2,500 residents. That is why Big Sky, which is unincorporated, operates as a resort area district while West Yellowstone is an incorporated resort community.

The part that decides your invoice is MCA 7-6-1503(2). The resort tax applies to the retail value of goods and services sold within the district by four named establishment types, and only those four:

• hotels, motels, and other lodging or camping facilities
• restaurants, fast food stores, and other food service establishments
• taverns, bars, night clubs, lounges, and other public establishments serving alcohol by the drink
• destination ski resorts and other destination recreational facilities

Separately, establishments that sell "luxuries" must collect the tax on those luxuries, and 7-6-1501(3) defines luxuries as gift or luxury items normally sold to the public or to transient visitors, expressly excluding unprepared food, medicine, medical supplies, appliances, hardware supplies and tools, and necessities of life.

A janitorial contractor is not a lodging facility, a restaurant, a bar, or a destination recreational facility, and cleaning labor is not a gift item sold to a tourist. The tax reaches the hotel's room charge, not the invoice the hotel's cleaning vendor sends it. The rate itself is capped at 3 percent under 7-6-1503(1)(a), with an additional levy of up to 1 percent available for infrastructure funding in qualifying districts.

Two caveats worth keeping. First, a cleaning company that also sells product retail inside a resort district — retail-packaged supplies from a storefront, for example — is in different territory than one billing service contracts, and that retail line should be checked against the local ordinance. Second, resort districts administer their own collections, so if you have any doubt about your specific service line, the district's tax administrator is the right call rather than the state.

Montana's other narrow taxes stay clear of cleaning work as well. The lodging facility use tax applies to hotel and short-term rental stays, not to a housekeeping company's labor charges even when hotels and vacation rentals are its clients. The rental vehicle sales tax applies to vehicle rentals.

Worked example: a Bozeman janitorial contract

A janitorial company billing $8,000 a month for office cleaning services in Bozeman, outside any designated resort district, issues that invoice with zero sales tax, since there is no state, county, or general municipal sales tax anywhere in Montana. Now move that same contract 45 miles south to a hotel in Big Sky, inside a resort area district that levies a local resort tax. The cleaning company's invoice is still untaxed. Under MCA 7-6-1503(2)(a), the resort tax reaches goods and services sold by lodging facilities, food service establishments, alcohol-serving establishments, and destination recreational facilities. Your client is one of those establishments; you are not. The hotel collects resort tax on the room it rents to a guest. It does not collect resort tax on the janitorial services it buys from you, and you do not collect it either. The one line worth a second look is retail product: if you sell packaged supplies over a counter inside the district rather than consuming them on a service contract, check that against the district's ordinance.

What this means for running a cleaning business in Montana

• No state sales tax registration required. There is no Montana Department of Revenue sales tax account to open, since the tax does not exist at the state level.
• No use tax on supply purchases. Unlike most other states in this guide, Montana cleaning businesses generally don't pay a state sales or use tax when purchasing chemicals, equipment, or supplies for their operations.
• Resort districts do not change your service invoice. MCA 7-6-1503(2)(a) limits the resort tax to four establishment types, none of which describe a janitorial contractor. Work in Big Sky, West Yellowstone, Whitefish, or Red Lodge the same way you work in Billings. The only line that warrants a look is over-the-counter retail product sold inside the district.
• Simpler pricing model than most states. Without a sales tax to calculate, collect, and remit, Montana cleaning businesses can build simpler, more transparent client quotes than operators in states like Minnesota or Nebraska.
• Multi-state operators should not assume parity. A business expanding into a neighboring state like Idaho (largely exempt) or North Dakota (also largely exempt for janitorial work) will still encounter a fundamentally different compliance framework than Montana's complete absence of sales tax.

Montana in context with other no-tax and low-tax states

Montana's complete absence of a sales tax puts it in the same practical category as New Hampshire for cleaning businesses, though Montana's resort-district exception introduces a narrow local wrinkle that New Hampshire's framework does not have.

Operating without a general sales tax simplifies invoicing but does not remove the analysis, because a contractor here will eventually bid work in a state that taxes services. The AICPA state and local tax resource center sets out the nexus and registration questions that arise the first time a crew crosses into a taxing jurisdiction, which is a threshold most growing companies hit before they have a compliance function.
