Property Taxes in Idaho
Idaho's property taxes run genuinely low by national standards -- a statewide average effective rate of roughly 0.49%-0.53% -- anchored by a real, broadly available homeowner's exemption, though this record discloses real, meaningful variation by county and even by ZIP code rather than one flat statewide figure.

Learn moreThe homeowner's exemption is Idaho's central property-tax relief mechanism
Idaho exempts 50% of a primary residence's assessed value from property tax, capped at $125,000 of exempted value (raised from a $100,000 cap in 2021) -- filed with the county assessor. This is a real, meaningful, and broadly available benefit applied automatically for coded primary residences in the place-level records reviewed for this build, distinct from more narrowly income-qualified programs in some other states.
Idaho's statewide average runs low, but real county and ZIP-level variation applies
Tax Foundation cites Idaho's statewide average effective rate at approximately 0.50%; other aggregators cite 0.49%-0.53% depending on methodology -- a real, disclosed spread, though all sources agree Idaho sits among the lowest-property-tax states nationally. Place-level records built alongside this one disclose real variation: Boise's own median effective rate runs around 0.59% (above Ada County's broader 0.46% median, reflecting Boise's relatively higher home values), Kootenai County's runs a disclosed 0.36%-0.64% depending on citation, and Bonneville County's (Idaho Falls) runs roughly 0.43%-0.79%.
Confirm your specific county and even ZIP code directly before budgeting
Given this real, disclosed variation -- and intra-city spreads as wide as Boise's own 83702 ZIP (0.77% median effective rate) versus 83709 (0.43%) -- confirm your specific target property's current rate and homeowner's-exemption eligibility directly with the county assessor rather than relying on one statewide Idaho property-tax figure.
