Gather evidence: recent comparable sales, appraisal reports, photographs, repair invoices, and plats or surveys.
Request an informal review or conference with the Assessor's Office; many adjustments are resolved informally before formal filing.
File a formal appeal with the appropriate board or commission if informal review does not resolve the issue. The state-level process may apply for some disputes; see the Missouri State Tax Commission for certain review paths Missouri State Tax Commission^[3].
Attend the hearing and present evidence. Hearings typically allow sworn testimony, witness statements, and documentary exhibits.
If the decision is adverse, follow the post-decision appeal route specified in the decision notice; this may include judicial review or additional administrative petitions.
