An appeal of an assessment listed on the property roll must be filed on or before the end of the county’s normal business hours on the fourth Monday of June. An appeal of an assessment listed on the subsequent property roll must be filed on or before the end of the county’s normal business hours on the fourth Monday of November.

The board of equalization may consider an appeal only if it is timely filed.
