Informational notice
Figures describe the median homeowner household in St. Clair 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.
The rate held while the market moved
St. Clair County sits in the quarter of U.S. counties whose effective rate moved least over this span: 2.5% up, against a median home value that rose 36.4%.
A near-steady rate on a moving market passes that movement straight through: the median bill rose 39.8%, from $518 to $724.
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
The bill here climbed steeply over 2020-2024, up 40% from $518 to $724. These ACS medians describe the reported change; they do not identify whether a levy, assessment, home value, or change in the responding households caused it.
The largest reported group here falls at the bottom of the national range: 13,283 of 29,001 owner-occupied homes (45.8%) report annual real-estate taxes under $800. This distribution describes reported owner-occupied homes, not an affordability judgment for any property.
The most forgiving PAIRING in the data, top-quartile household income with a bottom-quartile effective rate, puts the median bill at 0.9% of median household income. Home values still drive the dollar figure, which is why the ratio above varies widely among counties that share this position.
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.
Paying off the mortgage changes the picture here
31.8% of St. Clair County homes owned free and clear (3,864 of 12,142) report no property tax at all, against 11.3% of homes still carrying a mortgage. A reported zero is not proof of an exemption: it can equally mean a bill paid by another party, or a reporting artefact. But a gap this size is where age- and disability-based relief usually shows up, because those programmes reach owners who have finished paying.
What St. Clair County Homeowners Actually Pay
The single largest group of St. Clair County homeowners, 13,283 of 29,001 owner-occupied homes (45.8%), pays less than $800 a year. The median is one point in this spread, not a typical bill.
- Less than $800 45.8% (13,283)
- $800 to $1,499 23.2% (6,720)
- $1,500 to $1,999 6.0% (1,734)
- $2,000 to $2,999 3.8% (1,091)
- $3,000 or more 1.4% (407)

At 0.32%, St. Clair County sits in the lowest 3% of all U.S. counties by effective property-tax rate. A low rate does not by itself mean a low bill: the median here is $724, and what a homeowner actually pays depends as much on local home values as on the rate.

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.
