How this compares nationally
The population-weighted average modeled rate across indexed Montana counties is 0.77%. That modeled effective rate is below the broad national band many surveys use for orientation (often roughly 1–1.3% of home value, varying by source and methodology)—local bills still depend on your parcel.
Orientation band (~1–1.3%): broad U.S. survey context. See Tax Foundation — Property taxes as a percentage of owner-occupied housing value (state / local, illustrative national context).

FAQ
Common questions
Statewide orientation for Montana—open a county page for parcel-level rules.
What do these Montana county pages show?
Each indexed Montana county page uses U.S. Census Bureau ACS 2023 5-year county medians (B25103 / B25077) with an implied effective rate (median tax ÷ median value), plus state statutory and agency references.
Why is the statewide average different from one Montana county?
This hub averages population-weighted implied rates across 56 counties using POPESTIMATE2024 (or ACS B01003 where aligned in source data). Each county’s median tax ÷ median value reflects its own housing stock—not your parcel.
When are property taxes due in Montana?
Montana property taxes are collected in two installments in many counties—often November and May—confirm on your county treasurer statement.
How should I compare Montana counties to the rest of the U.S.?
Montana county pages use ACS 2023 medians—align comparisons to the same Census definitions; local assessments, classes (especially in Hawaii), and district millage drive actual bills. See our national context note and Rate Gazetteer’s methodology page.
