Figures describe the median homeowner household in Boise County as reported to the Census Bureau; your parcel can differ. Not tax, legal, or financial advice: check the county assessor or a qualified professional before decisions that depend on these numbers.
How to read this county's bill
The bill here climbed steeply over 2020-2024, up 27% from $1,272 to $1,611. These ACS medians describe the reported change; they do not identify whether a levy, assessment, home value, or change in the responding households caused it.
The fullest band here is the $800 to $1,499 range, holding 989 of 3,244 owner-occupied homes (30.5%). The band shows where the largest share of reported owner-occupied households falls; it is not an individual-bill estimate.
The most forgiving PAIRING in the data, top-quartile household income with a bottom-quartile effective rate, puts the median bill at 2.0% of median household income. Home values still drive the dollar figure, which is why the ratio above varies widely among counties that share this position.
The share above is the median annual bill divided by median household income, a ratio of two county-level medians rather than a household-by-household figure.

Each row is a separate ACS 5-year release, and consecutive releases share four of their five survey years. The percentage beside each bill is therefore movement in the published estimate against the previous release, not a single year's tax change. The two releases largely describe the same households. For change over time, compare releases that do not overlap.
