Why Iowa County's ACS bill runs high vs the U.S.

Informational notice
Figures describe the median homeowner household in Iowa 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.
A falling rate took the edge off
Iowa County's effective rate fell 15.2% across the 4-year span while its median home value rose 36.2%, leaving the median bill 15.5% higher at $4,038. That rate move is larger than the one in 64% of counties, so a good deal of the market's rise never reached the bill.
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
Bills rose across 2020-2024, from $3,495 to $4,038, a gain of 16%. This is a comparison of published ACS medians, not an explanation of a particular property's assessment or tax bill.
The heaviest band is also the fullest one here: 5,505 of 7,828 owner-occupied homes (70.3%) 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.
Both figures are in the national top quarter, and the median bill still equals only 4.9% of median household income. A high rate on high earnings produces a large dollar figure, and only the dollar figure tends to get quoted; the ratio above is the other half.
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.
What Iowa County Homeowners Actually Pay

Among the highest-taxed counties in the country
At 1.52%, Iowa County sits in the top 10% of all U.S. counties by effective property-tax rate. That is the rate, not the bill: a high rate on a modest home can still produce a smaller cheque than a low rate on an expensive one, which is why the $4,038 median bill is the number to compare against another county.

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.
