Informational notice

Figures describe the median homeowner household in Louisa 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 Louisa County rose 39.1%, from $107,900 to $150,100. The effective rate fell 20.5% over the same span, a steeper move than in 84% of U.S. counties.

The median bill still rose 10.6%, to $1,751. 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

Bills rose across 2020-2024, from $1,583 to $1,751, a gain of 11%. This is a comparison of published ACS medians, not an explanation of a particular property's assessment or tax bill.

The fullest band here is the $800 to $1,499 range, holding 819 of 3,401 owner-occupied homes (24.1%). The band shows where the largest share of reported owner-occupied households falls; it is not an individual-bill estimate.

Earnings are in the national top quarter and the rate is above the midpoint, so the median bill represents 2.3% of median household income. A headline bill conflates the dollar figure with the proportion; the two come apart here, and the ratio above is the second of them.

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 Louisa County Homeowners Actually Pay

Below Iowa on both measures

Louisa County's effective rate runs 16% under the Iowa median and its bill 40% under. Both sitting on the same side means the gap is not a valuation artefact: a county can post a low rate purely because its homes are expensive, but then the bill rises to meet the state. Here it does not, so the $1,751 median bill reflects a genuinely lighter charge than the Iowa norm rather than a different denominator. Compare it against the state page before reading anything into the county rank.

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.
