How Montana sales tax is calculated
Sales tax in Montana is calculated by multiplying the pre-tax purchase price by the applicable combined rate. The formula is simple:
Sales Tax = Purchase Price × 0.000% (avg combined)
Total = Purchase Price + Sales Tax
The exact rate depends on where the purchase occurs, the state base rate (0.000%) plus any local city or county add-ons. Montana allows local jurisdictions to add their own taxes, so the rate varies by location.

Montana sales tax in context: rates, history, and neighbors
Montana is one of five US states with no state sales tax, the others being Alaska, Delaware, New Hampshire, and Oregon. Montana funds state government primarily through individual income tax (top rate 5.65% for 2026 income), corporate income tax, mineral severance taxes, and natural resource royalties. Resort communities (Whitefish 3%, Big Sky 4%, West Yellowstone 3%, Gardiner 3%, Red Lodge 3%) charge a local Resort and Recreation Tax on tourist-oriented purchases (lodging, restaurants, bars, recreation), Montana residents typically get exempted by showing a state ID. Compared to neighbors: Idaho (6%), Wyoming (~5.44% combined), North Dakota (~7.05%), South Dakota (~6.10%), Canada (5%+ GST/HST), Montana's no-tax status makes it a popular cross-border shopping destination for Idahoans and Wyoming residents.

Collecting sales tax in Montana: business guide
Montana has no general statewide sales tax, so there is nothing to register for, collect, or remit at the state level, and no economic-nexus threshold to track for Montana sales. If you sell to customers in other states, you may still owe sales tax there once you meet those states' thresholds, but Montana itself imposes none. A few Montana resort or tourist localities levy narrow local taxes on lodging or prepared food; check the specific jurisdiction if that applies to you.
Montana-specific business compliance details
Montana businesses do not collect a general state sales tax, there is none. Most Montana businesses have no sales tax registration or compliance burden. Resort tax businesses (in qualifying resort communities) must register with their local resort tax board and file monthly. Out-of-state businesses selling to Montana customers have no Montana state sales tax obligations. Montana businesses selling to other states must comply with those states' economic nexus rules. Montana's lack of sales tax simplifies compliance dramatically, most businesses only deal with income tax, payroll tax, and property tax obligations. The resort tax compliance is location-specific, only ~15 Montana communities have resort taxes.
