Tax relief and valuation review
A homestead exemption, senior-relief program, or valuation protest can change the amount a homeowner owes—but only if the filing reaches the right local office in the correct window. Use the verified county guidance below as your working checklist, then confirm the current form and deadline with Marion County Assessor and Collector of Revenue.

Appealing an assessment
Use the valuation notice and the county’s published protest guidance to determine the last day to file. Do not assume the payment deadline controls the appeal.
Gather comparable sales, photographs, repair records, appraisal evidence, property characteristics, and any documentation that explains why the assessed value is incorrect.
Submit through the official channel, save the confirmation, and attend the board or review hearing if one is scheduled. An appraiser or attorney can help evaluate evidence when the value or stakes are substantial.
The verified protest guidance for this county is: July 13, 2026 (the second Monday in July), the statutory county Board of Equalization filing deadline; a Missouri State Tax Commission complaint is due September 30, 2026, or within 30 days after the Board of Equalization decision, whichever is later. If the language is not a specific calendar date, contact the office promptly for the current notice and board-review schedule.
