Montana Property Tax Calculator
Montana has no general sales tax, which leaves property tax carrying a substantial share of local budgets. Values are appraised, mill levies are adopted by the county, city, and school system serving your address, and the product of the two becomes your annual bill. Relief programs and appeals exist for those who qualify or disagree. County medians feed the estimates here — pick a Montana county above.

Methodology
Rates are aggregate-derived from the Census Bureau's ACS 2024 5-year American Community Survey (total real-estate taxes paid ÷ total home value, by county). This is a statistical estimate, not a bill lookup — actual property tax bills vary by city, school district, and special-district levies layered on top of the county rate, and by any homestead, senior, veteran, or other exemptions you qualify for. Montana ranks #35 of 51 (including DC) by statewide average effective rate, where #1 is the highest.

Frequently asked questions
How is property tax calculated in Montana?
A value is appraised for your property, and the mill levies adopted by the county, city, and school system that serve your address are applied to it. The calculator above stands in for that levy detail with a county-median effective rate.
How much property tax will I pay in Montana?
Your county and home value determine the estimate. Select a Montana county above, enter the value, and you'll see annual and monthly figures derived from official county-level data.
Can I lower my Montana property tax bill?
Assistance programs reduce the burden for qualifying lower-income homeowners and some seniors and veterans, and appraised values can be appealed when they overstate the market. Watch the deadlines attached to each.
Are property taxes deductible?
On an itemized federal return they fall under SALT, which carries a cap set in statute. Confirm the operative cap with IRS guidance for your filing year.
