How do I use the Montana sales tax calculator?

Enter the ZIP code where the buyer receives the order, or start typing the address and pick a suggestion, then enter the price. The calculator shows the combined rate for that ZIP and its state, county, city and district parts, the sales tax on the price, and the total.

What if I sell to buyers in other states?

Most states tax a remote sale at the rate where the buyer receives it, so a seller based in Montana may still have to collect other states’ sales tax where it has nexus. The US sales tax calculator looks up the rate for any state’s ZIP codes.

This is an estimate based on location alone. The tax you owe also depends on what you sell, who you sell to and the exact delivery address. If you intend to rely on these rates, use the Kintsugi platform (opens in a new tab).

How the Montana calculator works

Montana has no statewide sales tax. Some resort communities charge a local resort tax on certain goods and services, which this calculator doesn’t include.

Every Montana ZIP code returns 0%, so there’s no sales tax to add to a price. For the formula and worked examples, see how to calculate sales tax. Rates are as of September 2026.
