Idaho property tax by county
The median Idaho homeowner pays $2,006 a year in property tax on a home worth $376,000, an effective rate of 0.53%. That ranks Idaho #44 of 51 states, against a national 0.98%.
Why the county matters more than the state
Nez Perce County charges an effective 0.87% and Valley County 0.30%, a spread of 0.57 points inside one state. Property tax in the United States is set by counties, cities, school districts and special districts, not by states. A statewide figure is a weighted average of thousands of separate decisions, and it can be a poor guide to any particular address.
Idaho sits 0.45 points below the national effective rate. A low rate is not the same as a low bill: on an expensive home it can still produce a large one. House prices in the state moved +3.5% over the year to 2026 Q2, which changes the denominator of this rate over time.
