The Assessment and Taxation Department is responsible for a variety of tasks: appraisals of both real and personal property; keeping track of ownership of land; mailing tax statements; and collecting taxes to be turned over to the Finance Department. This Department keeps track of 43,758 properties within the County. Staff is responsible for insuring the accuracy of assessed values, processing recorded documents and assigning values to newly created parcels. The reappraisal of these properties is an ongoing process. We calculate a tax levy for each of the 64 districts each year. This includes cities, schools, Fire Districts, Cemetery Districts and a variety of other taxing authorities, who use the tax roll to generate their revenue source. The Director of A&T certifies a total assessed value each year. Once the roll has been certified, the tax statements can be generated and money collected. The Taxation side of this department collects the tax money and figures the allocation of all tax dollars to each district
