Most searches for a Montana sales tax exemption start from an assumption that holds in other states: register, get an exemption or resale certificate, and hand it to your vendors. Montana doesn't work that way. The state has no general sales or use tax, so there is no statewide sales tax to be exempt from, and the Montana Department of Revenue does not issue a general sales tax exemption certificate.
That doesn't make every Montana transaction tax-free. A few selective taxes apply inside the state, and Montana businesses that buy from or sell into other states deal with those states' rules. This guide covers both. It is educational information, not tax advice.
Does Montana have a sales tax?
No. The Montana Department of Revenue states plainly that Montana does not have a general-use sales tax, and there is no general use tax on retail goods either.
A few things follow from that:
- Montana retailers don't collect state sales tax on ordinary goods and services sold in Montana.
- There is no general economic nexus threshold in Montana. Remote sellers shipping ordinary goods to Montana customers have no Montana sales tax to collect.
- Online shopping doesn't change the picture. The Department notes that the Wayfair decision does not affect Montanans buying goods or services online, because Montana has no general sales tax to collect.
Is there a Montana sales tax exemption certificate?
Not for general purchases. Because there is no general sales tax, the Department of Revenue does not issue statewide exemption certificates for retail purchases.
That also applies when Montana residents shop elsewhere. Montana has no exemption certificate that works in other states. A Montana resident buying in a state that has a sales tax should check that state's revenue department for its rules on nonresidents.
You may see references to a "Montana resale certificate" or "Montana business exemption certificate" for purchases inside Montana. None is needed, because there is no Montana sales tax to exempt. The one related form, covered next, is for buying from vendors in other states.
Buying inventory out of state: the Montana Business Registry Resale Certificate
The Department of Revenue publishes the Montana Business Registry Resale Certificate for Montana buyers purchasing goods outside Montana for resale in the ordinary course of business. You give it to an out-of-state seller as evidence that your business is registered in Montana.
What to know before you rely on it:
- The vendor doesn't have to accept it. The out-of-state seller may accept it as a substitute resale certificate to exempt the sale from its own state's tax, but it isn't required to.
- Not every state accepts it. Some states require their own state-specific form or additional information.
- You need a Montana business registration number. The form asks for it, and sellers can verify it through the Montana Secretary of State's business name search.
- The resale certification is binding. You certify that you'll resell the items and use them only for demonstration and display while they're held for sale. If you use them any other way, you may owe use tax.
In practice, ask each vendor what documentation it accepts before placing a tax-exempt order, and keep a copy of every certificate you issue. For more on how cross-state resale documentation works, see our guide to out-of-state resale certificates.
Montana taxes that do apply
| Tax | Rate | What it covers |
|---|---|---|
| Lodging facility sales and use tax | 8% combined (4% sales + 4% use) | Total amount paid for accommodations |
| Rental vehicle tax | 4% | Base rental charges for vehicles rented for less than 30 days |
| Local resort tax | Up to 3%, plus up to 1% more for infrastructure in some communities | Goods and services sold by lodging, food service, bars, destination resorts, and luxury sellers in voter-approved resort communities and areas |
Lodging facility sales and use tax
The combined 8% tax applies to the total amount the purchaser pays for accommodations. Separately stated charges for meals, transportation, entertainment, and similar items aren't included. Units or spaces rented for 30 or more continuous days to the same purchaser are exempt.
Lodging businesses need a seller's permit before doing business and file quarterly returns through the Department's TransAction Portal (TAP), due by the last day of the month after each quarter. Short-term rental marketplaces and online hosting platforms collect on the stays they facilitate; operators remain responsible for bookings made outside those platforms.
Lodging exemptions are narrow. The Department's Form LTE covers U.S. government employees when the charge is billed directly to and paid by the agency. Montana state employees and employees of other states pay the tax.
Rental vehicle tax
The 4% tax applies to base rental charges for vehicles rented for less than 30 days, including cars, light trucks, motorcycles, boats, off-highway vehicles, and certain trucks and trailers under 22,000 pounds. Rental vendors and third-party rental platforms need a seller's permit and file quarterly on Form RVT.
Local resort taxes
State law lets voters in qualifying resort communities authorize a municipal resort tax, and lets resort areas adopt one through a county petition and election. The rate can't exceed 3%, and some communities may add up to 1% for infrastructure. It applies to goods and services sold by lodging and camping facilities, food service businesses, bars serving drinks, and destination ski resorts and recreational facilities, and to luxuries. Sales for resale are exempt. Rates and filing procedures are set locally, so confirm them with the community where you operate.
Other selective taxes
Montana also taxes cannabis (4% on medical and 20% on adult-use sales, plus an optional local tax of up to 3%), tobacco products, and telecommunications services under separate statutes, each with its own exemptions.
Selling into other states
Montana's lack of a sales tax stops at the state line. A Montana business with customers in states that impose sales tax has to evaluate those states' economic nexus and marketplace rules, and register and collect where required. Buying inventory tax-free for resale is a separate question from whether you have to collect tax on your own sales in another state. For a primer on thresholds, see economic nexus, simplified.

Frequently asked questions
Is Montana sales tax exempt?
Montana doesn't have a general sales tax, so ordinary retail purchases in Montana carry no state sales tax. Selective taxes still apply to lodging, rental vehicles, certain products such as cannabis, and sales in resort communities that have adopted a local resort tax.
Does Montana issue a resale certificate?
Montana doesn't issue a sales tax resale or exemption certificate for Montana purchases. The Department of Revenue does publish the Montana Business Registry Resale Certificate, which a registered Montana business can offer to out-of-state vendors when buying goods for resale.
Do out-of-state vendors have to accept the Montana Business Registry Resale Certificate?
No. A vendor may accept it as a substitute resale certificate, but it isn't required to. Some states require their own form or additional information.
Do nonresidents pay tax when they buy in Montana?
Ordinary purchases carry no Montana sales tax. Visitors still pay the 8% lodging facility sales and use tax on accommodations, the 4% rental vehicle tax on qualifying rentals, and any local resort tax where one applies.
Do remote sellers have to collect tax on sales shipped to Montana?
Not for ordinary goods. Montana has no general sales tax, so there is no economic nexus threshold for general retail sales. Businesses selling taxable lodging or vehicle rentals in Montana must get a seller's permit and collect those taxes.
