Informational notice
Figures describe the median homeowner household in Will 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
Will County's effective rate fell 12.9% across the 4-year span while its median home value rose 33.5%, leaving the median bill 16.3% higher at $7,173. That rate move is larger than the one in 53% 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 $6,166 to $7,173, a gain of 16%. 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: 178,804 of 202,150 owner-occupied homes (88.5%) 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.
Both figures are in the national top quarter, and the median bill still equals only 6.5% of median household income. A high rate on high earnings produces a large dollar figure, and only the dollar figure tends to get quoted; the ratio above is the other half.
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 Will County Homeowners Actually Pay
The single largest group of Will County homeowners, 178,804 of 202,150 owner-occupied homes (88.5%), pays $3,000 or more a year. The median is one point in this spread, not a typical bill.
- Less than $800 2.2% (4,487)
- $800 to $1,499 1.9% (3,787)
- $1,500 to $1,999 1.4% (2,836)
- $2,000 to $2,999 4.0% (8,186)
- $3,000 or more 88.5% (178,804)

Among the highest-taxed counties in the country
At 2.24%, Will County sits in the top 1% 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 $7,173 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.
