Appeals Process

Assessor Level Real Property Appeals

Appeals for real property value or its classification are held May 1st thru June 1st. During this time you may appeal your value by mail, email, fax, or in person. (Should these dates fall on Saturday, Sunday, or legal holiday, it shall be deemed to have been timely filed on the next business day.)

Real property is reappraised by the Assessor’s Office every odd-numbered year. The value determined by the Assessor for the year of reappraisal is generally used for the intervening year also. 

The actual value of real property is based on its value as of the appraisal date, which is June 30 of the year prior to the reappraisal year. The appraisal data used to establish the value is from the 24-month period ending June 30 of the year prior to the reappraisal year.

Mill Levies may vary in different tax areas. We review appeals for the valuation of the property only, not the amount of taxes you pay.

The value of residential property is based on the market approach to value. Generally, the value of all other property is based on consideration of the market, cost, and income approaches to value.
