Montana Sales Tax — Frequently Asked Questions
What is the sales tax rate in Montana?
Montana is one of five U.S. states with no general sales tax — there is no statewide sales tax and no local sales tax. You generally pay $0 in sales tax on retail purchases in Montana, though some narrow categories (lodging, prepared food, rental cars) may carry their own excise taxes. The other no-sales-tax states are Alaska (no statewide rate, but some local), Delaware, New Hampshire, and Oregon.
How is sales tax calculated in Montana?
Because Montana has no general sales tax, the formula sales tax = price × rate evaluates to $0 at the default 0% rate. You can still use this calculator if you cross a border to shop in a neighboring state — enter that state's combined rate in the Tax Rate field and the calculator will compute tax and total for you.
What is exempt from Montana sales tax?
Because Montana has no general sales tax, the question of exemptions does not apply to most retail purchases. Note however that specific categories — lodging, prepared meals, rental cars, alcohol, and tobacco — may still carry state or local excise taxes that look and feel like sales tax. Check the receipt: those line items are real, they are just not called sales tax.
Do I owe sales tax on online purchases in Montana?
No — because Montana has no general sales tax, online retailers do not collect Montana sales tax at checkout, and there is no general use-tax liability on purchases you make from out-of-state sellers. If you have items shipped to an address in another state, that state's sales-tax rules apply to the transaction, not Montana's.
Why does my actual Montana sales tax differ from this estimate?
Because Montana has no statewide sales tax, the default 0% calculation matches what you pay on most retail transactions. The main reasons a receipt might show tax anyway are: a specific excise tax (lodging, prepared food, rental car, alcohol, tobacco), a city or borough that does levy a local sales tax (relevant in Alaska only), or a transaction shipped from or to another state where that state's sales tax applies.
