What you still pay
No state sales tax does not mean no tax at all. Montana raises money in other ways, and some goods carry their own taxes, such as fuel, tobacco, alcohol and hotel stays.
Good to know
No state or local sales tax (special taxes in local resort areas are not counted by the source).
Buying online
Since the 2018 Wayfair decision, most online sellers charge sales tax based on the delivery address, so an online order shipped to Montana is taxed at Montana rates, not the seller's.

Sources and assumptions
- State rates are the general sales tax rate on most goods. Groceries, clothing, cars, services and hotel stays can be taxed differently.
- Local rates are state averages; the exact local rate depends on the city, county and district of the sale or delivery address.
