How this ranking is calculated

The effective property tax rate is the median annual property tax paid divided by the median home value in each county, expressed as a percentage. It is the most practical way to compare property tax burden between counties because it neutralizes differences in home values.

Counties with the highest rates in Idaho often share a few characteristics: lower home values and/or higher millage rates driven by school and local service funding needs.
