The evidence
Boards act on value, not frustration.

The process
How Missouri handles appeals.
Missouri reassesses in odd-numbered years, and assessors must notify you when your value increases. The path runs: informal review with the county assessor’s office, appeal to the county Board of Equalization (generally filed by the second Monday in July), and then a fresh appeal to the State Tax Commission, whose hearing officers function much like a tax court. Residential property is assessed at 19% of market value, so the fight is over the market value behind that math — and decisions lean heavily on adjusted comparable sales as of January 1 of the reassessment year, which is what a licensed appraisal puts on the record.
Worth knowing in Missouri
The State Tax Commission level is where documentation quality really pays: it decides value fresh on the evidence presented, without deference to the BOE’s number.
