What to check on your notice
The typical Montgomery County home gained 6.2% in the year to January 2026. A notice that rose far more than that, or a value above what similar homes nearby actually sold for, is the usual starting point for an appeal.
Keep the state's limits in mind: Residential property is assessed at 19% of true value. Statute requires a physical inspection before the assessor raises a residential value more than 15% since the last assessment (not counting new construction). This is an inspection rule, not a hard cap.
How a Missouri appeal works
Values in Montgomery County are set by the local county assessor, and the appeal starts there. The rules below apply statewide; your notice has the exact dates and office for your property.
| Who sets the value | County assessor. Each county assessor, and the City of St. Louis assessor, values property. Missouri reassesses in odd-numbered years and the values usually carry into the next even year. |
|---|---|
| Valuation date | January 1 of each odd-numbered year |
| Your notice | Notice of Assessed Valuation Increase |
| Deadline | Appeal to your county Board of Equalization before the second Monday in July. The board may extend the date. St. Louis City follows the second Monday in July. Jackson County has listed the third Monday in June as its 2026 deadline, so always check your own county. |
| First step | Informal review with the county assessor, then a hearing before the county Board of Equalization. |
| If you still disagree | Appeal to the Missouri State Tax Commission by September 30 of the assessment year or within 30 days of the Board of Equalization decision, whichever is later. |
| Form | Complaint for Review of Assessment (State Tax Commission, filed online with a copy of the board decision) |
| Fee | No fee to file an appeal with the State Tax Commission. |
Reading this in fall 2026? The 2026 Board of Equalization window has closed. Missouri's next general reassessment is as of January 1, 2027, so the realistic next chance is the 2027 board window: forms and notices come out in spring 2027 and the statutory deadline is before the second Monday in July 2027 (July 12, 2027), though some counties set earlier dates. If you lost at the board this year, you have until September 30 or 30 days after the board decision, whichever is later, to appeal to the State Tax Commission.
- In even years, values generally carry over, so reassessment years (odd years) are the main opening.
- The county board may extend its deadline, but do not count on it.
- St. Louis City hearings run from the first Monday in July through the fourth Saturday in August, and Jackson County hearings may begin July 13, 2026.

- Bring a recent appraisal or a sales contract if you bought the home recently.
- Bring comparable sales near January 1 of the reassessment year and photos of condition issues.
- In St. Louis City, bring six copies of anything the board should review.
