Informational notice
Figures describe the median homeowner household in Knox 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
Knox County's effective rate fell 16.1% across the 4-year span while its median home value rose 54.8%, leaving the median bill 29.9% higher at $3,786. That rate move is larger than the one in 69% 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
The bill here climbed steeply over 2020-2024, up 30% from $2,914 to $3,786. 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: 9,229 of 14,551 owner-occupied homes (63.4%) 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 the income and the rate here sit in the third quarter nationally, and the median bill is 5.1% of median household income. Two above-average figures pulling in opposite directions is why the rate on its own is a poor guide.
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.
