FAQs

How do I appeal a supplemental assessment?

You must file an application for reduced assessment no later than 60 days from the date of mailing of this notice. We always encourage you to contact our office at (530) 283-6380 for a review of your assessment prior to filing a formal appeal. Please note: If there have been multiple changes of ownership within the same tax year, the supplemental notice may reflect no change in value for the subsequent transfers, although supplemental taxes or a refund may be due if there has been an increase or decrease in value since lien date, January 1. Supplemental taxes are based on the change in value from lien date to the date of transfer, prorated for your period of ownership.
