Director of Equalization

The value determined by the assessor is the assessed value and is the value indicated on the assessment roll.

The Assessor does not: Collect taxes, Calculate taxes, Determine tax rate, or Set policy for the Board of Review. The Assessor is concerned with value, not taxes. The taxes you pay are proportionate to the value of your property compared to the total value of the taxing district in which your property is located.
