How sales tax works in Montana

Groceries, prescription drugs and some other categories are often taxed at a lower rate or exempt.

Note: No general sales tax (a few resort towns levy a local-option tax).

For online orders shipped to Montana, the seller generally collects the buyer's local rate (destination sourcing) if they exceed the state's economic-nexus threshold. See how US sales tax works and sales tax vs use tax.
