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 Welge. “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.
