Residential assessed values in Macon County rose nearly half over the past decade while agricultural assessed values rose about 9%, shifting a larger share of the real-property tax base onto homes, according to Missouri State Tax Commission county tables for tax years 2015 and 2025.
Residential assessed valuation, combining rural and town lots, climbed from $81.0 million in 2015 to $118.9 million in 2025, a 46.8% increase, the commission's Table III reports show. Agricultural assessed valuation rose from $19.8 million to $21.5 million, or 9.0%.
Residential property's share of the county's locally assessed real property grew from 64.6% in 2015 to 66.3% in 2025. Agriculture's share fell from 15.8% to 12.0%. Total locally assessed real property rose from $125.5 million to $179.5 million over the same span.
The pattern matches a statewide trend. The Missouri Independent reported in May 2026 that residential assessments rose 75% statewide since 2015 while agricultural assessments rose 14%. Both of Macon County's increases were smaller than the statewide figures.
Every county that borders Macon showed the same direction: residential assessed value grew faster than agricultural assessed value from 2015 to 2025, according to the same State Tax Commission tables.
- Adair: residential +54.0%; agricultural +11.8%
- Chariton: residential +43.7%; agricultural +9.0%
- Knox: residential +47.6%; agricultural +11.6%
- Linn: residential +26.3%; agricultural +10.8%
- Monroe: residential +50.6%; agricultural +14.5%
- Randolph: residential +42.4%; agricultural +4.7%
- Shelby: residential +40.4%; agricultural +9.2%
Among the eight counties, Linn had the smallest residential increase and Adair the largest. Randolph had the smallest agricultural increase. Monroe had the largest agricultural increase among the neighbors.
Assessed value is the figure local governments multiply by their tax rates. It is not the market price of a house or an acre. Missouri assesses residential real property at 19% of market value and agricultural real property at 12% of productive value under state law, so the two subclasses are not valued the same way. The commission tables report the assessed amounts counties certified, not the underlying market or productive values.
2027 is a statewide reassessment year. Odd-numbered years are when Missouri assessors update real-property values for the next tax cycle. The 2015 and 2025 figures already reflect prior reassessment cycles; they do not preview what Macon County's 2027 values will be.
The State Tax Commission publishes county subclass totals each year in its annual report. The figures above come from Table III for tax year 2015 (the Seventieth Annual Report) and tax year 2025 (the Eightieth Annual Report).
