Informational notice
Figures describe the median homeowner household in Whiteside 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 8.7% down between 2020 and 2024, a smaller shift than in 65% of U.S. counties. With the median home value rose 17.9%, the median bill rose 7.7% to $2,598: 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
Very little moved here between 2020 and 2024: the typical bill went from $2,413 to $2,598, a change of 8%. The comparison describes county-level medians only; individual assessments and bills can differ.
The heaviest band is also the fullest one here: 6,805 of 17,786 owner-occupied homes (38.3%) 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.

Among the highest-taxed counties in the country
At 2.04%, Whiteside County sits in the top 2% 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 $2,598 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.
