Informational notice
Figures describe the median homeowner household in Union 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
Union County's effective rate fell 15.3% across the 4-year span while its median home value rose 44.7%, leaving the median bill 22.6% higher at $918. That rate move is larger than the one in 65% 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
Bills rose across 2020-2024, from $749 to $918, a gain of 23%. 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: 2,539 of 7,353 owner-occupied homes (34.5%) report annual real-estate taxes under $800. This distribution describes reported owner-occupied homes, not an affordability judgment for any property.
Both sides of this comparison sit low: household income here is in the bottom quarter of US counties, and so is the effective tax rate. The median bill works out at 1.7% of median household income, which is the arithmetic of a modest levy on modest earnings rather than of any deliberate relief.
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
31.2% of Union County homes owned free and clear (1,124 of 3,603) report no property tax at all, against 18.2% 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 Union County Homeowners Actually Pay
The single largest group of Union County homeowners, 2,539 of 7,353 owner-occupied homes (34.5%), pays less than $800 a year. The median is one point in this spread, not a typical bill.
- Less than $800 34.5% (2,539)
- $800 to $1,499 22.6% (1,663)
- $1,500 to $1,999 7.0% (517)
- $2,000 to $2,999 6.1% (452)
- $3,000 or more 5.1% (377)

1,805 homes here (24.5%) report no real estate tax at all, a sizeable minority for a county this size. Exemptions are set by state: how Mississippi handles assessments and appeals.

Below Mississippi on both measures
Union County's effective rate runs 22% under the Mississippi median and its bill 24% under. Both sitting on the same side means the gap is not a valuation artefact: a county can post a low rate purely because its homes are expensive, but then the bill rises to meet the state. Here it does not, so the $918 median bill reflects a genuinely lighter charge than the Mississippi norm rather than a different denominator. Compare it against the state page before reading anything into the county rank.

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.
