How the Missouri system works

County assessors maintain property values; county collectors generally collect taxes.

County or city assessors determine market and assessed value. Real property is commonly reassessed in odd-numbered years, personal property is assessed annually, and local Boards of Equalization hear formal appeals.

Before opening a property portal

  • Identify whether the task concerns value, payment, recorded documents or an appeal.
  • Use the official office or authorized portal listed on a completed county page.
  • Do not assume a county office handles municipal assessment where the state uses city or town systems.
  • Confirm filing dates for the current year before submitting an exemption or appeal.
