Is there sales tax in Montana?

No statewide sales tax. Montana is one of five states without one, along with Alaska, Delaware, New Hampshire, Oregon. Montana has no general sales tax. Some resort areas charge their own resort taxes, which the Tax Foundation's table doesn't count.


State sales tax rate	0%
Average local rate	0%
Average combined rate	0%
Combined rate rank (1 = highest of 50 states)	47 (tied, no sales tax)

Using the calculator

The rate starts at 0%. Buying in a neighboring state, or ordering from a seller that charges another state's tax? Type that rate in. For example, at 6% a $100 purchase costs $106.00. You can also take tax out of a total, or work out the rate from a receipt.

Tax = price × rate ÷ 100 · Total = price + tax

Limitations

No sales tax doesn't mean no tax on purchases: lodging, meals, fuel and similar items can have their own taxes.
Rates change. Check the Montana revenue department for anything specific.

Compare every state on the sales tax by state page.
