Save time (and a stamp!) by filing your 2023 personal property assessment online. Just find the e-filing website and unique secure access code on the form mailed from the St. Charles County Assessor at the end of January. Assessment forms must be completed and returned to the Assessor by March 1.
Personal property assessments must be filed every year. Those who do not turn it in may be charged a late filing penalty fee of up to $105 and experience delays in renewing or registering license plates. For more information, visit the Assessor’s website. For questions, please call 636-949-7420.
