Montana sales tax
Montana has no sales tax. There is no state sales tax and no local sales tax, so the price on the shelf is the price you pay. Montana is one of five states with no general sales tax. You can still owe tax on some specific purchases, and buying from Montana does not always exempt you from your own state's use tax, both covered below.
What is the Montana sales tax rate in 2026?
There is no rate. Montana levies no general sales tax at the state level, and its local governments do not levy one either. That is different from a state like Alaska, which has no state rate but where individual cities and boroughs do charge their own.
No general state or local sales tax; state law does allow a handful of designated resort communities (e.g. Whitefish, Big Sky, Red Lodge) to levy a local-option resort tax up to roughly 3% on lodging, restaurants, and luxury goods.
What is the sales tax rate in my county in Montana?
Every one of Montana's counties has its own page with the rate, its components, and what the rate does not cover: Montana sales tax by county. The rate does not vary in Montana, but the county pages carry the exemptions and the caps, which is where it gets complicated.
What is unusual about sales tax in Montana?
No general state or local sales tax; state law does allow a handful of designated resort communities (e.g. Whitefish, Big Sky, Red Lodge) to levy a local-option resort tax up to roughly 3% on lodging, restaurants, and luxury goods.
When does a business have to collect Montana sales tax?
It does not. With no sales tax to collect, Montana has no seller registration requirement and no economic nexus threshold. Selling into Montana from another state creates no Montana sales tax obligation.
Selling from Montana is a different question: if you ship to customers in states that do tax, their thresholds apply to you. The economic nexus checker covers those.
How do I find the exact sales tax rate for an address in Montana?
Use the state's own lookup rather than an average. Montana publishes an official rate finder at https://mtrevenue.gov/, which returns the combined rate for a specific address. That is the figure that governs what you charge or what you should have been charged.
The flat truth on Montana sales tax
Montana does not charge sales tax, full stop. The thing that catches people out is use tax: if you live in a state that does tax and you buy in Montana to avoid it, you generally owe use tax at home. Enforcement is uneven, the obligation is not.
