Platte County personal property forms are due by March 1
March 1 is the date to circle after the January 1 snapshot. Platte County values personal property owned on the first day of January, then expects the annual assessment form back by March 1 to avoid late filing fees.
The list can include motor vehicles, motorcycles, trailers, boats, mobile homes, aircraft, farm machinery, livestock, grain, and boat docks. That is why a driver, farmer, or boat owner should treat the form as more than junk mail. It is the front end of the tax record.
Here the Assessor and Collector have separate jobs. Assessment is the list-and-value step. Collection is the bill, payment, and receipt step after the assessment turns into taxes due. If a vehicle is missing, sold, or tied to the wrong address, fix the assessment record first. Once the tax is paid and proof is needed for plates, the errand moves to the collector receipt side.
