Butler County, Missouri property-tax payment and appeal deadlines
Tax bills, payment rules, and valuation-review windows are controlled by the local jurisdiction and the governing state framework. The reviewed record below separates published figures from items that still require confirmation with Butler County Assessor (Chris Rickman).
Rate context
Confirmno single countywide effective average published; Missouri property-tax rates vary by local taxing district.
Statement mailing
PublishedNovember 1, 2026; Butler County’s official FAQ states property-tax statements are typically mailed November 1 each year.
Payment deadline
PublishedFor the 2026 tax year, Butler County taxes are due and payable November 1 and may be paid through December 31, 2026 without penalty and interest; a December 31 postmark or timely drop-box deposit is accepted.
Valuation protest
PublishedInformal assessment appeals must be completed by July 1, 2026; Butler County says its Board of Equalization is typically held the third Monday in July (July 20, 2026). 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.
Do not assume a grace period.
The reviewed record identifies the payment timing above but does not establish a universal penalty schedule for this page. Late charges, interest, collection costs, tax-sale procedures, and lien or foreclosure timelines can depend on state law and the local collector’s process. If the deadline is close or a balance is delinquent, contact the tax collector directly and request the current payoff amount in writing.
Treat a published payment deadline as a hard operational date and retain your receipt or confirmation number.
From assessment to collection
01Valuation and notice
Review the assessment notice as soon as it arrives. The protest window may run from the notice date rather than from the payment due date.
02Statement and account review
Match the tax statement to the parcel or account number and confirm exemptions, assessed value, taxing units, credits, and balance.
03Payment confirmation
Use the official collector channel, then save the receipt, transaction reference, and date posted. A bank submission is not always the same as a county posting date.
