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 Boone County Assessor (Kenny Mohr).
Relief programs
The filing guidance for this county is: April 1 through 5:00 p.m. June 30, 2026, for the Boone County Senior Real Estate Tax Relief Program’s 2026 base year; no general homestead exemption was verified. A 2026 base-year credit is expected on the 2027 bill. Use the official form or application channel, provide the residence and ownership documentation requested, and keep a copy of the submission.
Open homestead applicationBoone County Senior Real Estate Tax Relief Program: Boone County resident age 62 or older before January 1 of the initial credit year, owner or qualifying interest holder of a primary-residence homestead, and liable for the real-property tax. The 2026 base-year application period was April 1–June 30, 2026; renewal is automatic for approved participants under the 2026 amended policy.
No general local annual valuation cap was verified. Boone’s senior program credits the increase in eligible homestead tax liability over the participant’s base year and does not cap market or assessed value; Missouri uses odd-year reassessment and 19%/12%/32% statutory ratios.
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 (second Monday in July statutory county Board of Equalization filing deadline; no separate 2026 Boone deadline was published in the official sources reviewed). The Missouri State Tax Commission complaint deadline is September 30, 2026, or within 30 days after the county 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.
