Informational notice
Figures describe the median homeowner household in Twin Falls 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.
The rate gave way faster than almost anywhere
Between the 2020 and 2024 releases the median home value in Twin Falls County rose 85.6%, from $182,100 to $337,900. The effective rate fell 24.2% over the same span, a steeper move than in 92% of U.S. counties.
The median bill still rose 40.6%, to $2,066. Where the rate drops this far and the bill rises anyway, what changed is the value the rate is applied to.
Effective rate is the published median bill divided by the published median home value, so the two multiply back to the bill exactly; the rate's movement here is derived from those two figures rather than read from the rounded published rate. Both are ACS 5-year survey estimates for the median owner-occupied household, compared across non-overlapping releases. They describe what the Census published, not a local policy, assessment, or exemption change.
How to read this county's bill
The bill here climbed steeply over 2020-2024, up 41% from $1,469 to $2,066. 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 plurality of owner-occupied homes here falls in the $2,000 to $2,999 band, at 6,080 of 24,488 (24.8%). This shows the reported distribution around the county median, while individual assessments can vary.
Above-median earnings meet a slightly-below-median rate, and the median bill amounts to 3.1% of median household income. That is the comfortable middle of this dataset, and comfortable middles are easy to overlook when only rankings get published.
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.
