How this compares nationally
The population-weighted average modeled rate across indexed Idaho counties is 0.55%. 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 Idaho—open a county page for parcel-level rules.
What do these Idaho county pages show?
Each indexed Idaho 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 Idaho county?
This hub averages population-weighted implied rates across 44 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 Idaho?
Idaho property taxes are often payable in two halves (many counties: December and June)—verify dates on your county treasurer bill.
How should I compare Idaho counties to the rest of the U.S.?
Idaho 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.
