Revised Missouri Statute 137.115.9 In accordance with state statute, the Assessor shall use the trade-in value published in the October issue of the National Automobile Dealers' Association Official Used Car Guide, or its successor publication, as the recommended guide of information for determining the true value of motor vehicles described in such publication. In the absence of a listing for a particular motor vehicle in such publication, the Assessor shall use such information or publications which in the Assessor's judgment will fairly estimate the true value in money of the motor vehicle. In most cases, the average trade-in value of the base model is used as a basis of assessed value. Vehicles are assessed using a ratio of 33 1/3% of the trade-in value of the vehicle. (October Issue - NADA Average Trade-In Value) / 3 = Assessed Value

Personal property tax is a tax based on the value of tangible personal property. Personal Property is anything that is not real estate.
Revised Missouri Statutes 137.115 and 137.120 Taxable personal property consists of motor vehicles, trailers, mobile homes (situated on leased/rented land), watercraft, boat motors, aircraft, livestock, farm machinery and equipment, agricultural crops and any other personal property not exempted by law. RSMo 137.115 and 137.120 Also taxable is “business personal property”. This is tangible personal property used in a trade or business, or used for production of income and has a "useful" life of longer than one year. However, supplies used by a business are taxable as well. Revised Missouri Statute 137.122
Revised Missouri Statute 137.075 Every person owning or holding tangible personal property on the first day of January, including all such property purchased on that day shall be liable for taxes thereon during the same calendar year. However there are exceptions as noted in this summary.
You can submit documentation to support a possible value adjustment due to mileage or condition. You should attach the documentation to your declaration that must be returned no later than March 1. This documentation should identify the vehicle by its VIN and should be in the form of a State inspection, oil change or repair receipt, insurance settlement. Mileage documentation should be dated as close to January 1 of the tax year as possible. For condition adjustments, a written estimate of repairs is required, unless insurance documentation is provided. Photographs are not sufficient documentation.

The North American Industry Classification System (NAICS) is the standard used by Federal statistical agencies in classifying businesses for statistical purposes related to the economy. The use of this code provides uniformity for statistical purposes. It groups establishments into industries according to similarity in processes used to produce goods or services. NAICS replaced the Standard Industrial Classification (SIC) system in 1997. The Assessor’s Office is collecting this data to aid in more accurate assessment and classification of the many different types of businesses we have within St. Louis County. This code, along with other data such as real estate type (residential or commercial), total assessed value and number of employees, gives a clearer picture of the businesses located in our County.
