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.
- Payment deadline
- For the 2026 tax year, Missouri real-estate and personal-property taxes are due December 31, 2026; a December 31 postmark is timely where the county accepts mailed payment.
- Assessment appeal
- July 13, 2026 (second Monday in July statutory county Board of Equalization filing deadline). 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.
Exemptions & appeals
Senior relief
Benton County Commission minutes dated October 7, 2024 record adoption of an ordinance authorizing an SB 190/SB 756 property-tax credit for eligible senior citizens’ primary residences; current 2026 eligibility and filing instructions were not published in official sources reviewed.
Valuation limits
No general local annual valuation cap was verified. The county’s SB 190/SB 756 authorization is a tax credit limiting eligible tax liability, not a cap on market or assessed value; Missouri uses odd-year reassessment and 19%/12%/32% statutory real-property assessment ratios.
For a valuation appeal, use the appeal date in the tax and filing section above. Keep your notice, supporting evidence, and proof of submission.
