How this is calculated
The effective property tax rate is the median real-estate tax bill divided by the median home value — both for owner-occupied homes, from the U.S. Census Bureau's American Community Survey (ACS 5-year estimates)1. Median income is also from the ACS1. Federal and state income-tax figures use IRS2 and Tax Foundation3 data.
About Jefferson County, ID
Jefferson County’s 0.447% effective property tax rate sits just a hair above Idaho’s statewide median of 0.446% — a difference so slight it barely registers, yet enough to place the county 22nd among the state’s 44 counties. That middle-of-the-pack ranking signals a fairly ordinary position within Idaho, where property taxes generally run well below the national median of 0.794%. The gap against that national figure is substantial: homeowners here pay roughly half the rate a median U.S. county would charge. On a median home value of $408,400, the annual tax bill comes to about $1,824. With median household income at $86,679 and per-capita income of $31,834, that bill amounts to a modest slice of yearly earnings. Communities like Lewisville, Menan, and Terreton reflect the county’s rural character, where property taxes tend to stay restrained.
