Montana Has No Sales Tax

Montana is one of five US states with no sales tax at any level — state, county, or city. All purchases made in Montana are completely free from sales tax. This makes Montana attractive for large purchases, and many residents of neighboring states (Idaho, Wyoming, North Dakota, South Dakota) cross the border for significant shopping trips.

Local and special taxes in Montana

Montana does not layer county or city general sales tax on top of a state rate. Businesses should still review gross receipts, lodging, and industry-specific taxes that may apply.

Use tax and online purchases

Residents who buy taxable goods from out-of-state sellers without tax collected may owe use tax in their home state when required. Marketplace facilitators often collect tax on behalf of remote sellers once economic nexus thresholds are met.

What shoppers should know

Tax-free shopping in Montana can attract cross-border purchases from neighboring states. For large-ticket items, confirm whether delivery to another state triggers tax in the destination state instead.

Common mistakes to avoid

Assuming every purchase is tax-free

Montana may still have local sales taxes, lodging taxes, or special excise taxes depending on location and product type.

Ignoring use tax on untaxed online orders

If tax was not collected at checkout, your home state may require use tax on taxable goods used locally.

Using this page for business registration

Confirm zero-rate treatment with the official tax agency before assuming no permit or filing obligation.

Cross-border shopping without documenting delivery
