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; Boone County’s official Collector page states that 2026 e-billing/tax statements occur in November, but no specific paper-mail day was published.
- 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; 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.
Exemptions & appeals
View exemption application (opens in a new tab)Exemption filing
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.
Senior relief
Boone 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.
Valuation limits
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.
For a valuation appeal, use the appeal date in the tax and filing section above. Keep your notice, supporting evidence, and proof of submission.
