Learn moreA moderate implied effective property tax rate
Columbus's total city-jurisdiction millage rate ran 115.89 mills -- under Mississippi's standard 10%-of-true-value residential assessment ratio, that implies an effective rate of approximately 1.16%, a calculated estimate this record discloses as such.
A real, current property reassessment
Lowndes County's Mississippi Department of Revenue-driven reassessment raised home values by an average of approximately 18%, with a cited example tax bill rising roughly 21% -- and neighboring Golden Triangle counties enter the same new appraisal cycle in 2026.
Mississippi's real, current 4% flat income tax
Mississippi taxes income above $10,000 (single) / $20,000 (married filing jointly) at a flat 4% for 2026, with Social Security and qualified retirement income fully exempt statewide, no income or age limit.
Key takeaways
- Columbus's implied effective property tax rate runs approximately 1.16% (calculated).
- A real, current Lowndes County reassessment is raising home values and tax bills.
- Mississippi's 4% flat income tax (2026) and full retirement-income exemption apply statewide.
