Assessment notices are sent in the spring each year and typically reach your mailbox by the middle of May.
Each property owner receives an assessment notice that contains both the market value and assessed value, along with an estimate of your property tax bill. The median tax bill in Benton County is $3,052, compared with the national median property tax bill of $2,400. West Richland has the highest median home price at $396,520.
