Platte County Assessor's Office
The Assessor assesses all real and personal property within the county including land, homes, commercial buildings, businesses, mobile homes, aircraft, vehicles, and other personal property. Our goal is to accurately value your property while providing you the best possible service with a trained and qualified staff.
While our office does not impose or collect property taxes, it’s important that our assessments are done accurately and on time as the money that is collected from property taxes is used to fund schools, libraries, fire protection, emergency services, and many other governmental services that support the communities where we live.
At the beginning of each year, Platte County residents and businesses will receive a Personal Property Assessment form to be completed and returned by March 1.
Our mission is to partner with the taxpayer to ensure accurate, consistent and transparent assessments — never overvaluing or undervaluing property — while providing exceptional service through a qualified staff and simple, convenient services.
