When can I appeal my assessed value?

Under State law, if the January 1 market value of your property falls below the assessed or taxable value as shown on the tax bill issued in the same year (i.e., January 1, 2009 and tax bill fiscal year 2009/10 issued September 2009), the Assessor’s Office is required to lower the assessment. This type of property tax relief generally applies to recently purchased property. Appeals may be filed between July 2 and November 30 for the annual roll. For supplemental events, or escaped assessments, the appeal must be filed within 60 day of the mailing date of the notice. Appeal forms can be obtained and must be filed with the Clerk of the Board. For more information, call (925) 655-2008.
