Informational notice
Figures describe the median homeowner household in Johnson 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 11.6% down between 2020 and 2024, a smaller shift than in 53% of U.S. counties. With the median home value rose 36.6%, the median bill rose 20.8% to $1,992: 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
Bills rose across 2020-2024, from $1,649 to $1,992, a gain of 21%. 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: 1,140 of 3,362 owner-occupied homes (33.9%) 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 3.2% 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 Johnson County Homeowners Actually Pay

Below Illinois on both measures
Johnson County's effective rate runs 38% under the Illinois median and its bill 62% 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 $1,992 median bill reflects a genuinely lighter charge than the Illinois 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. For change over time, compare releases that do not overlap.
