California Code, Government Code - GOV § 13995.112

An assessed business may appeal an assessment to the county commission upon the basis that the business does not meet the definition established for an assessed business within its industry segment, or that the level of assessment is incorrect. If the error is based upon failure of the business to provide the required information in a timely manner, the county commission may recommend to the county a fine to be collected by the county treasurer/tax collector as a condition of correcting the assessment.
