HOW MISSOURI APPEALS WORK
THE SHORT VERSION

Missouri assesses homes at 19 percent of market value and lets you appeal to the county board of equalization by the second Monday in July, then to the State Tax Commission by September 30. An appeal makes sense when comparable sales show your value is too high.

WHEN AN APPEAL MAKES SENSE
  • Recent comparable sales show your market value is too high.
  • Your home is valued higher than similar homes nearby.
  • Your county just reassessed (odd year) and the value overshot the market.
WHEN IT USUALLY WILL NOT
  • Your bill went up but your value is fair. Local levies set the rate, not the assessor.
  • You missed the second Monday in July. The board cannot take a late appeal.

Read the full explanation

In Missouri, your county assessor sets your home's market value in odd numbered years and assesses residential property at 19 percent of that value. You appeal the value, not your tax bill, to the county board of equalization by the second Monday in July. If the board denies you, you can appeal to the State Tax Commission by September 30. An appeal helps when recent comparable sales show your value is too high. It usually will not help just because your bill went up, since local levies set the tax rate. This is general information, not tax advice.
