Exemptions & appeals

Exemption filing

No general Missouri homestead exemption form was verified. 2026 personal-property assessment lists are generally due March 1, 2026; late filing can incur the statutory penalty.

Senior relief

No separate countywide senior freeze was verified in official sources reviewed. Eligible seniors, disabled individuals, and qualifying surviving spouses may apply for Missouri's Property Tax Credit (circuit breaker) through the Missouri Department of Revenue; eligibility and income limits apply.

Valuation limits

No general local annual valuation cap was verified. Missouri real property is generally reassessed in odd-numbered years; statutory assessment ratios are 19% residential, 32% commercial, and 12% agricultural. New construction and qualifying changes are assessed annually. A county senior tax credit, where authorized, limits tax liability rather than market or assessed value.

For a valuation appeal, use the appeal date in the tax and filing section above. Keep your notice, supporting evidence, and proof of submission.
