Informational notice
Figures describe the median homeowner household in Jefferson 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 10.2% down between 2020 and 2024, a smaller shift than in 59% of U.S. counties. With the median home value rose 47.2%, the median bill rose 32.2% to $3,082: 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
The bill here climbed steeply over 2020-2024, up 32% from $2,331 to $3,082. 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 heaviest band is also the fullest one here: 87,029 of 170,969 owner-occupied homes (50.9%) 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 most forgiving PAIRING in the data, top-quartile household income with a bottom-quartile effective rate, puts the median bill at 2.8% 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.

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.
