ST. CHARLES COUNTY, Mo. – Personal property assessment forms will be hitting mailboxes soon and people may see an increase in the assessed value of certain items.

St. Charles County will be mailing out about 181,000 personal property assessment forms for 2022 by January 26. Those completed forms need to be returned to the Assessor by March 1.

The increase in accessed value is likely to be seen in other counties as well.

“Taxpayers may see an increase in assessed value of certain items on their assessment form,” says St. Charles County Assessor Scott Shipman. “The used automobile market has seen an uptick in prices since the beginning of the COVID-19 pandemic. Many factories were closed and a number of car dealerships either temporarily closed or had little or no inventory, forcing many to purchase used vehicles.”

Scott Shipman, the St. Charles County Assessor, says large fleet companies that sell a large number of cars in the used market also were reluctant to sell their fleet because they were uncertain when they would be able to replace them. Shipman says the uptick in prices is a result of supply constraints.

He says as supplies return to normal, prices should eventually return closer to normal as well.

State statutes say the value is to be determined using information from the National Automobile Dealers’ Association Official Used Car Guide. The statute says a vehicle “shall not be assessed at a value greater than the average trade-in value without performing a physical inspection of the vehicle.”

There are several ways you can file your personal property:

  • Online – Individual personal property owners have the option to file online after receiving the assessment form in the mail. The e-filing website, account number, and unique secure access code for the individual personal property owner are printed in a green box on the top third of the form. The e-filing website also will be available through the Assessor’s website, Those who filed online in previous years should note that the unique access code changes each year. E-filing also allows personal property owners to save and print their completed 2022 assessment for their records after it’s submitted. 
  • Mail – Complete the form and send to: St. Charles County Assessor, 201 N. Second Street, Room 141, St. Charles, MO 63301.
