This page is for informational purposes only and is not tax, legal, or financial advice. Figures describe the median homeowner household in Knox 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.
Most of the market's rise reached the bill
The effective rate here moved 11.0% down between 2020 and 2024, a smaller shift than in 55% of U.S. counties. With the median home value rose 35.0%, the median bill rose 20.1% to $842: 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
Bills rose across 2020-2024, from $701 to $842, a gain of 20%. This is a comparison of published ACS medians, not an explanation of a particular property's assessment or tax bill.
The largest reported group here falls at the bottom of the national range: 509 of 1,096 owner-occupied homes (46.4%) report annual real-estate taxes under $800. This distribution describes reported owner-occupied homes, not an affordability judgment for any property.
Earnings are below the national midpoint while the rate is above it, and the median bill equals 1.5% of median household income. The gap between those two positions is the whole story on this page.
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 Knox County Homeowners Actually Pay
The single largest group of Knox County homeowners, 509 of 1,096 owner-occupied homes (46.4%), pays less than $800 a year. The median is one point in this spread, not a typical bill.
- Less than $800 46.4% (509)
- $800 to $1,499 28.4% (311)
- $1,500 to $1,999 5.3% (58)
- $2,000 to $2,999 7.5% (82)
- $3,000 or more 8.6% (94)

Same rate as Missouri, a smaller bill
The effective rate here sits within 2% of the Missouri median, yet the median bill runs 57% below it. When the rate matches and the cheque does not, the difference is in what is being taxed, not how heavily: the same percentage applied to cheaper housing produces $842 here. That is why comparing counties on rate alone can invert the answer a homeowner actually cares about.

Property Tax History · UNDER · LIGHT
| Year | Median Tax (vs prior release) | Effective Rate |
|---|---|---|
| 2024 | $842 +7.9% | 0.83% |
| 2023 | $780 -0.9% | 0.80% |
| 2022 | $787 +0.6% | 0.88% |

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 notably lower than the national average of 0.92% puts Knox County in the "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 Knox County or any other county.

What tax filers report in Knox County
Of the 1,740 federal returns filed from Knox County in 2022, 30 (1.7% of filers) itemised and reported real estate taxes on Schedule A, averaging $1,633 each. The largest group was filers with adjusted gross income of $50-75k, who accounted for 100% 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.
