Montana Sales Tax Calculator
Estimate the total price after sales tax on a purchase in Montana.
Sales tax in Montana
Montana is one of the states with no statewide sales tax. That means a listed price is generally the price you pay at checkout, with no state-level tax added on top.
How this estimate works
We multiply your purchase amount by Montana's estimated combined sales tax rate to get the sales tax amount, then add that to your original price to get the total price after tax. Because local county and city taxes can stack on top of the state rate and vary by jurisdiction, the actual rate you're charged at a specific store may differ slightly from this estimate.
This tool provides an estimate for planning purposes only and is not a substitute for checking the exact rate in your city or county. See our national sales tax calculator to compare other states.
Frequently Asked Questions
What is the sales tax rate in Montana?
Montana has no statewide sales tax, so the rate is effectively 0% at the state level.
Does Montana have no sales tax?
Yes. Montana is one of five US states — alongside Delaware, Montana, New Hampshire, Oregon, and Alaska (at the state level) — that charge no statewide sales tax, instead relying on other revenue sources like income tax or property tax.
Is the rate shown here exactly what I'll pay at checkout in Montana?
Not necessarily. The figure above is an estimated combined state-plus-average-local rate, but actual sales tax in Montana can vary by the specific city or county where you shop, since local jurisdictions often add their own tax on top of the state rate. Treat this as a solid planning estimate rather than an exact quote.
How do I calculate sales tax on a purchase in Montana?
Multiply your purchase amount by Montana's sales tax rate (0.00%) expressed as a decimal, then add that tax amount to your original price to get the total. Enter any purchase amount above and this calculator does that math for you instantly.
Are groceries and clothing taxed the same as other purchases in Montana?
Not always. Many states, potentially including Montana, exempt or reduce the tax rate on groceries, prescription medication, and sometimes clothing, while taxing general merchandise at the full rate. This calculator applies a general estimated rate and doesn't account for category-specific exemptions.
Does sales tax apply to online purchases shipped to Montana?
In most cases, yes. Since a 2018 Supreme Court ruling, most online retailers are required to collect sales tax based on the buyer's location, so an online purchase shipped to Montana is generally taxed similarly to an in-store purchase there.
Does Montana charge sales tax on car purchases?
Many states apply standard sales tax to vehicle purchases, though some use separate vehicle excise taxes, different rate structures, or reduce the taxable amount for a trade-in. Check Montana's specific vehicle tax rules with your local DMV before budgeting for a car purchase.
Is Montana a high sales tax state?
Montana has no statewide sales tax, making it one of the most favorable states for shoppers on that front, though other taxes like income or property tax may be higher to compensate.
