How to Appeal Your Property Tax Assessment in Missouri
The general appeal process in Missouri:
- Meet the deadline: Appeal to the county Board of Equalization must be lodged with the county clerk (as secretary of the board) on or before the second Monday in July of the assessment year; the board may in its discretion extend the time for filing. In 2026 the second Monday in July is July 13, 2026. After the board acts, an appeal to the State Tax Commission must be filed by September 30 of the year of the ruling, or within 30 days after the final action of the board of equalization, whichever date later occurs.
- File a appeal: Contact your county's BOE or file online through your county's online portal.
- Gather evidence: Market analysis, recent comparable sales, and documentation of property defects or errors.
- Attend your hearing: Present your evidence to the County Board of Equalization.
- Escalate if needed: After the initial hearing, consider County Board of Equalization (BOE).
Evidence and Hearing Tips
Strong evidence for a Missouri property tax appeal typically includes comparable sales data, a recent licensed appraisal, and documentation of any property defects or errors in your assessment record.
Hearings are conducted by the County Board of Equalization (BOE). Most appeals are resolved informally before a formal hearing.
