Property Taxes in Hattiesburg

Hattiesburg property tax runs through a real, genuine, county-split mechanism this record discloses precisely rather than reducing to a flat rate: Mississippi assesses Class I residential property at 10% of true value, then applies local millage rates, producing a real, disclosed spread between Hattiesburg's Forrest County side (~1.58%, this record's primary citation) and its Lamar County side (~1.26%).

Mississippi's Real Assessment-and-Millage Mechanism, Not a Flat Rate

Mississippi's Constitution assesses Class I (single-family, owner-occupied residential) property at a real, current 10% of true (market) value -- that assessed value is then multiplied by the local millage rate (set by each county, city, and school district) to produce the tax bill. This record discloses this real, genuine multi-layer mechanism directly rather than reducing it to one flat percentage.

A Real, Disclosed Spread Between Hattiesburg's Two Counties

Hattiesburg genuinely spans both Forrest County (most of the city, including downtown and the USM campus) and Lamar County (the western portion). Ownwell-style effective-rate citations ran approximately 1.58% for the Forrest County side (this record's primary metric) and approximately 1.26% for the Lamar County side -- both above the national median (~1.02%), with Forrest County's figure also running above Mississippi's own statewide median (cited at approximately 1.31%-1.35%) and Lamar County's figure running modestly below it.

A Real, Disclosed Cross-Methodology Spread on Both Counties

This record separately found lower, average-percent-of-assessed-value-style citations for both counties (approximately 0.82%-0.85% for Forrest County, approximately 0.66% for Lamar County) -- a real, disclosed methodology gap this record does not resolve against the higher, effective-rate-style citations above, since the two calculation approaches (percent of ASSESSED value vs. actual bill divided by actual market value) are not directly comparable.

A Real, Current (January 2026) Senior/Disabled Homestead Exemption Expansion

Effective January 1, 2026, Mississippi's senior (65+)/disabled homestead exemption on assessed value increased from $7,500 to $12,500, per 2025's HB 1255 (amending Miss. Code Ann. Section 27-33-67) -- given the state's 10% Class I assessment ratio, this real, current, genuinely significant expansion shields up to $125,000 of a qualifying home's TRUE value from all property tax entirely. Reimbursement to local taxing bodies begins in the 2027 calendar year.

Confirm the Actual Certified Rate and Resulting Bill for a Specific Property

Given Mississippi's real, multi-layer assessment-and-millage mechanism and the real, disclosed cross-source and cross-county spread on comparison figures, confirm the actual current property tax bill for a specific Hattiesburg property directly with the Forrest County or Lamar County Tax Assessor's Office rather than relying on any single figure in this file.
