Informational notice

Figures describe the median homeowner household in Clay 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

Clay County's effective rate fell 17.6% across the 4-year span while its median home value rose 15.4%, leaving the median bill 4.9% lower at $1,392. That rate move is larger than the one in 75% 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

This is one of the counties where the typical bill came down, from $1,463 in 2020 to $1,392 in 2024, a fall of 5%. The source reports the change but does not distinguish among rate, value, or household-composition effects.

The largest reported group here falls at the bottom of the national range: 1,356 of 4,211 owner-occupied homes (32.2%) report annual real-estate taxes under $800. This distribution describes reported owner-occupied homes, not an affordability judgment for any property.

A top-quartile rate meets below-median earnings here, and the median bill reaches 2.3% 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.

The published bill went DOWN here

Between the 2020 and 2024 ACS releases the median annual property tax in Clay County fell from $1,463 to $1,392, a change of -4.9%. Fewer than three counties in a hundred recorded any decline over this period; nearly everywhere else the published figure rose. A fall can reflect reassessment, a shifting mix of the homes surveyed, or genuine rate relief, and these estimates cannot separate those causes.

What Clay County Homeowners Actually Pay

Below Illinois on both measures

Clay County's effective rate runs 29% under the Illinois median and its bill 74% 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 $1,392 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.
