Tax bills & filing dates
These are the dates and qualifications recorded in the directory. Confirm your tax year and current deadline with the official office and your property’s notice.
- Tax bill mailing
- November 2026; the official Collector site publishes November tax-bill notices but no specific 2026 mailing day.
- Payment deadline
- 2026 real-estate and personal-property taxes are due December 31, 2026; payment must be received or postmarked by December 31 to avoid statutory penalty and interest.
- Assessment appeal
- July 13, 2026 (the second Monday in July), the statutory County Board of Equalization valuation-appeal filing deadline; a Missouri State Tax Commission appeal is generally due September 30, 2026, or within 30 days after the BOE decision, whichever is later.
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 DeKalb County senior freeze or local senior exemption was verified in official county sources reviewed. The official Collector site directs eligible seniors and disabled taxpayers to Missouri Department of Revenue Form MO-PTC (Property Tax Credit/circuit breaker).
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.
