Question 1

What is the sales tax rate in Montana?

Accepted Answer

Montana charges no state or local sales tax in 2026. It is one of five US states with no statewide sales tax (Alaska, Delaware, Montana, New Hampshire, and Oregon).

Question 2

Do businesses in Montana ever collect sales tax?

Accepted Answer

Yes — when selling into other states. Since the 2018 Wayfair decision, a Montana business that exceeds another state's economic nexus threshold (commonly $100,000 in sales or 200 transactions per year) must register and collect that state's sales tax, even with no physical presence there.

Question 3

Is shopping in Montana tax-free for out-of-state visitors?

Accepted Answer

At the register, yes. But technically your home state may charge "use tax" on purchases you bring back — the self-reported counterpart to sales tax. Enforcement for personal purchases is rare, but businesses are audited on use tax regularly.

Question 4

Which states do charge sales tax?

Accepted Answer

45 states and the District of Columbia levy a statewide sales tax in 2026, ranging from 2.9% in Colorado to 7.25% in California. See the full table on our sales tax by state page, or use the calculator for any state.
