Informational notice
Figures describe the median homeowner household in Mahaska 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.
Most of the market's rise reached the bill
The effective rate here moved 8.3% down between 2020 and 2024, a smaller shift than in 66% of U.S. counties. With the median home value rose 39.5%, the median bill rose 27.9% to $2,077: the rate did comparatively little to offset the market.
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 28% from $1,624 to $2,077. 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 heaviest band is also the fullest one here: 1,703 of 5,942 owner-occupied homes (28.7%) report annual real-estate taxes above $3,000. That band has no upper edge in the source, so the county median understates the burden carried by the plurality rather than describing it.
The rate is in the national top quarter while earnings are only moderately above the midpoint, so the median bill claims 2.9% of median household income. A high rate is affordable only relative to something, and this is what it is relative to here.
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.
