Tax relief and valuation review

Protect your exemption and appeal rights.

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 McDonald County Assessor and Collector of Revenue.

What the local record says

Homestead filing

The filing guidance for this county is: McDonald County’s official Senior Citizens Tax Credit application was due May 31, 2026. The county’s separate 2026 SB 3 homestead property-tax credit was approved by voters, but the county stated implementation guidance and litigation made filing details unavailable at the time of review. Use the official form or application channel, provide the residence and ownership documentation requested, and keep a copy of the submission.

Open homestead application

Senior citizen tax relief

McDonald County Senior Citizens Tax Credit under county ordinance/SB 190: applicant must be at least 62 by January 1, 2026, own and occupy a primary homestead in the county, be the legal taxpayer, and have current taxes. The official application required return by May 31, 2026. The credit is based on eligible tax-liability increases over the 2025 base year.

Valuation cap or growth limit

No general local annual valuation cap was verified. McDonald County’s SB 190 senior program credits eligible homestead tax-liability increases over the 2025 base year rather than capping market or assessed value; Missouri ratios are 19% residential, 32% commercial, and 12% agricultural.

Appealing an assessment

Build the objection around evidence and the notice date.

Calendar the window

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.

Assemble support

Gather comparable sales, photographs, repair records, appraisal evidence, property characteristics, and any documentation that explains why the assessed value is incorrect.

File and preserve proof

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 under the Missouri statutory Board of Equalization filing deadline; McDonald County’s official 2026 BOE date was July 20, 2026, 8:00 a.m.–2:00 p.m., by appointment only. The Missouri State Tax Commission complaint deadline is September 30, 2026, or within 30 days after the BOE 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.
