Frequently asked questions
What is the sales tax rate in Montana?
Montana charges no state sales tax at all, so most purchases have no sales tax added at checkout, though a small number of localities or special-purpose taxes may still apply in specific cases.
How much sales tax is added to a $100 purchase in Montana?
Nothing at the state level, a $100 purchase stays $100 in most of Montana.
Does sales tax vary by city within Montana?
Montana's combined rate here uses the state's population-weighted average local rate, since per-city rate data for this state isn't broken out individually. Actual city/county rates can differ slightly from this average; confirm with the retailer or your state revenue department for an exact figure.
Is Montana sales tax charged on top of the price or included in it?
Sales tax in the US is added on top of the listed price at checkout, unlike VAT-style taxes that are baked into a sticker price. The calculator above supports both directions: adding tax to a price, or working backward from a total that already includes tax.
