Informational notice

Figures describe the median homeowner household in Decatur 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

Decatur County's effective rate fell 13.5% across the 4-year span while its median home value rose 37.6%, leaving the median bill 19.0% higher at $1,831. That rate move is larger than the one in 57% 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 $1,539 to $1,831, a gain of 19%. 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: 495 of 2,130 owner-occupied homes (23.2%) 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.

A top-quartile rate meets below-median earnings here, and the median bill reaches 3.1% of median household income. A rate ranking places this county by the rate alone; the ratio above is the figure that accounts for what is earned 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.

What Decatur County Homeowners Actually Pay

A high rate, a smaller bill

Decatur County taxes property at 1.61%, about 16% above the Iowa average, yet its median bill of $1,831 lands roughly 37% below it. The effective rate is the bill divided by the home's value, so a county can only sit on opposite sides of the state average this way when its homes are worth materially less than the state norm. The rate is the policy; the bill is what the housing market does with it.

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.
