The Jefferson County Appraiser's Office mailed their Ad Valorem Tax Returns (also known as "Renditions") on 12/30/2010. Per K.S.A.79-303: Every person who owns Tangible Personal Property shall list said property for assessment. Property held, and taxable to others, shall be listed with the Appraiser in the name of the owner thereof. The filing deadline for the Renditions is March 15, 2010 to avoid any penalties. If you do not receive a Rendition, but own taxable personal property, please contact the Jefferson County Appraiser's Office (785) 863-2080 for assistance. Thank you.
