Deadline and where to file
Saint Martins values are set by the local county assessor. 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.
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.
The Cole County guide covers the full Missouri appeal process: forms, fees, hearing levels and what happens next.
