tax bills

The St. Charles County Assessor will mail approximately 181,000 personal property assessment forms for 2023 by Jan. 26. Completed assessment forms are due to the Assessor by March 1. 

Due to the COVID-19 pandemic, taxpayers are strongly encouraged to file personal property using contactless methods: online, by mail, or in the drive-up drop outside the County Administration Building at 201 N. Second Street in St. Charles. 

Ways to File

  • 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 blue 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 2023 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. 
  • Drop Box – Completed assessment forms must be submitted in the "County" drive-up drop box outside the County Administration Building. The drop box is located on Monroe Street near the corner of N. Second Street.
  • In Person – Again, taxpayers are strongly encouraged to file personal property through contactless methods due to the COVID-19 pandemic. Those who wish to file in person can do so from 8 a.m.-5 p.m., Monday-Friday, excluding holidays, at the Assessor’s service windows at the County Administration Building, 201 N. Second Street in St. Charles. Forms also may be submitted in the indoor drop box located on the first floor of the Administration Building. Visitors will need to register for the Assessor’s queue through the QLess kiosk in the lobby, through the QLess app on their mobile device, or through the QLess link available at or Monitors in the lobby and a text notification on a mobile device will update those in the queue, and visitors will be alerted visually and audibly through the monitor or their mobile device when it is their turn to approach the windows. Staff at the security desk in the lobby are available to assist with QLess registration.

Additional Personal Property Assessment Information

By state law, the Assessor is charged with placing a fair market value on real and personal property, as property tax in Missouri is based on property value. Personal property assessments must be filed annually by those who own personal property and live in St. Charles County as of Jan. 1. Examples of personal property include vehicles, motorcycles, campers, boats and farm equipment. Those who fail to complete their personal property assessment may be charged a late-filing penalty up to $105. Additionally, failing to file a personal property assessment form may delay the ability to renew or register license plates for a vehicle.

“The tax rate for everyone in the county is impacted by those who do not declare their personal property,” says Shipman. “A fair and equitable distribution of taxes is assured when everyone submits the form by the deadline.” 

Residents can visit to verify the Assessor has received their completed assessment. Verification of assessment receipt is posted within two business days for online filing and as soon as possible for mail and drop box submissions after the assessment is received and processed. For questions about assessments, or if you are a new resident in the county and need to be added to the Assessor’s records, call the Personal Property office at 636-949-7420.
