According to the U.S. Census Bureau's American Community Survey (2024), the median Idaho homeowner pays $2,038 a year on a home worth $418,600, an effective rate of 0.49%.

How small is Idaho's share of U.S. property-tax collections?
In Census FY2024, Idaho's state and local governments collected $2.1B in property tax, only 0.29% of the national haul (#46 of 51). Spread across 514,361 owner-occupied homes, that haul is about $4,119 per home - 2.0× the ACS median homeowner bill of $2,038. The gap is expected: LF0009 covers all taxable property (including commercial and other non-household parcels), while the ACS median is a household figure.

Home values amplify the dollar bill
The median Idaho home is $418,600, compared with $227,791 nationally. This helps explain why two places with similar effective rates can still produce different annual dollar bills.
