How do I appeal my county property tax assessment in California if I believe it's too high?

To appeal your county property tax assessment, you must file a formal application with your county's Assessment Appeals Board and present evidence showing your property's value is lower than its assessed value. Here are the steps to appeal your property tax assessment in California: Step 1: Obtain the Application Form Contact your county's Clerk of the Board of Supervisors or visit their website to get an "Application for Changed Assessment." This is the official form to start the appeals process. Do not send this to the Assessor's Office; it goes to the appeals board. Step 2: File Your Application by the Deadline You must file the application within the strict filing period. For most counties, the regular period is from July 2 to September 15. Some counties have a later deadline of November 30. Check your county's specific deadline and ensure you file on time, as late applications are rarely accepted. Step 3: Gather Your Evidence The burden of proof is on you to show the assessor's value is incorrect. Collect strong evidence, such as: - Comparable Sales: Information on at least three similar properties in your area that sold for less than your assessed value around the January 1 lien date. - Photographs: Pictures showing your property's condition, especially if it has significant issues like a bad roof, cracked foundation, or other deferred maintenance. - Appraisals or Repair Estimates: A recent appraisal or written estimates from licensed contractors for necessary repairs. Step 4: Prepare For and Attend Your Hearing You will be notified of a hearing date before the Assessment Appeals Board. At the hearing, you will present your evidence and explain why you believe the assessment is too high. The County Assessor’s office will also present its evidence. Be prepared to answer questions from the board. Important Details and Nuances Your appeal must be based on the property's market value as of the January 1 lien date for that tax year. Your personal opinion of value or your inability to pay the tax bill are not valid reasons for an appeal. You are challenging the factual basis of the valuation. Warnings and Limitations You must pay your property tax bill on time, even if you have an appeal pending. If you do not pay, you will face steep penalties. If your appeal is successful, the county will issue a refund for the overpayment. The board has the authority to lower, uphold, or even raise your assessed value based on the evidence presented.
