Dade 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 Dade County Assessor Annette Black and Collector/Treasurer Jarromy O'Connor.
Rate context
Confirmno single countywide effective average published; Missouri property-tax rates are set by the county, cities, schools, and other local taxing districts.
Statement mailing
PublishedNovember 2026; Dade County states real-estate and personal-property statements are mailed in November, without a specific 2026 day.
Payment deadline
Published2026 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.
Valuation protest
PublishedJuly 13, 2026 (second Monday in July) for the County Board of Equalization; Dade County also advises taxpayers with an incorrect new value to contact the Assessor for an informal hearing. State Tax Commission appeal is generally due September 30, 2026, or within 30 days after the BOE 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.
