Informational notice

Figures describe the median homeowner household in Iroquois 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 11.0% down between 2020 and 2024, a smaller shift than in 56% of U.S. counties. With the median home value rose 28.4%, the median bill rose 14.3% to $2,504: 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 $2,190 to $2,504, a gain of 14%. 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: 3,354 of 9,154 owner-occupied homes (36.6%) 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.

The rate is in the national top quarter while earnings are only moderately above the midpoint, so the median bill claims 3.8% of median household income. A high rate is affordable only relative to something, and this is what it is relative to 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 Iroquois County Homeowners Actually Pay

Among the highest-taxed counties in the country

At 1.82%, Iroquois County sits in the top 4% 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 $2,504 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.
