How property taxes work in Idaho
Idaho property taxes are levied locally — typically a stack of county, municipal, school, and special-district rates applied to assessed value after any exemptions. The 0.50% figure on this page is an ACS effective rate (taxes paid ÷ owner-occupied home value), which is useful for comparing counties and modeling PITI. It is not the millage printed on a specific parcel's bill.
For millage, exemption filings, or an official estimate, use Idaho State Tax Commission.

Methodology
Statewide effective rates use 2024 ACS owner-occupied data. County rates are median real-estate taxes paid divided by median owner-occupied home value (ACS 2020–2024 5-year). Last reviewed August 13, 2026. Estimates only — confirm with the local taxing authority.
On a $400,000 home, the U.S. benchmark used for comparison is 0.90% ($3,600 / year).
