The latest release moved the bill up

This page is for informational purposes only and is not tax, legal, or financial advice. Figures describe the median homeowner household in St. Clair County as reported to the Census Bureau, your own bill can differ based on your parcel's assessed value, exemptions, special districts, and municipal overlays. Always consult your county assessor, tax collector, or a qualified professional before making decisions that depend on these numbers.
How to read this county's bill
The bill here climbed steeply over 2020-2024, up 27% from $760 to $966. 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: 1,122 of 3,093 owner-occupied homes (36.3%) report annual real-estate taxes under $800. This distribution describes reported owner-occupied homes, not an affordability judgment for any property.
Incomes here are in the lowest quarter nationally while the rate sits just below the middle, and the median bill lands at 1.8% of median household income. The rate reads as unremarkable in a national ranking; the earnings behind it are not, and the ratio above is where the two meet.
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 St. Clair County Homeowners Actually Pay
The single largest group of St. Clair County homeowners, 1,122 of 3,093 owner-occupied homes (36.3%), pays less than $800 a year. The median is one point in this spread, not a typical bill.

Property Tax History · QUIET · LIGHT
| Year | Median Tax (vs prior release) | Effective Rate |
|---|---|---|
| 2024 | $966 +6.0% | 0.61% |
| 2023 | $911 +4.6% | 0.64% |
| 2022 | $871 +5.7% | 0.69% |
| 2021 | $824 +8.4% | 0.73% |
| 2020 | $760 | 0.80% |
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.
Tax Burden
Tax Affordability Score
An effective rate well below the national average of 0.92% puts St. Clair County in the "Very Affordable" band for property tax burden.
How this score is calculated: a 1-10 scale derived mechanically from the ratio of this county's effective rate to the national average effective rate (0.92%) - a ratio at or below 0.5× scores 10, a ratio at or above 2.0× scores 1, with a linear scale between. It is a factual comparison of Census figures only, not a recommendation, quality rating, or endorsement of St. Clair County or any other county.

What tax filers report in St. Clair County
Of the 3,960 federal returns filed from St. Clair County in 2022, 50 (1.3% of filers) itemised and reported real estate taxes on Schedule A, averaging $2,720 each. The largest group was filers with adjusted gross income of $100-200k, who accounted for 60% of the county's reporting returns.
Two things this does not say. The amount is what filers reported, recorded before the $10,000 cap on combined state and local tax deductions applies, so it is not the amount deducted. And the share is of everyone who files a return, not of homeowners: most filers now take the standard deduction, so a minority itemise at all.
