Montana sales tax rate
Montana is one of a handful of states with no statewide general sales tax, so most retail purchases are not taxed at the state level. There is also no general local sales tax on most goods. A 0% general reference rate does not by itself prove that a transaction is exempt. Confirm the rules for the product, service, customer location and transaction before invoicing or filing.
