What is the process for appealing a decision made by the FTB to the California Office of Tax Appeals (OTA)?

To appeal a Franchise Tax Board (FTB) decision, you must file a formal written appeal directly with the California Office of Tax Appeals (OTA) before the strict deadline expires. This process moves your case from the FTB to an independent body for review. Here is the step-by-step process for filing your appeal: Step 1: Receive a Final Notice from the FTB You can only appeal after the FTB has made a final decision on your case. This decision will arrive in a letter titled either a "Notice of Action" (if the FTB denied your protest of a proposed tax assessment) or a "Notice of Determination Concerning Claim for Refund" (if the FTB denied your claim for a refund). The appeal clock starts on the date of this notice. Step 2: Determine Your Filing Deadline You have a very strict deadline to file your appeal with the OTA. - For a "Notice of Action," you must file your appeal within 30 days of the date on the notice. - For a "Notice of Determination Concerning Claim for Refund," you must file your appeal within 90 days of the date on the notice. Step 3: Prepare Your Written Appeal Your appeal is a formal letter to the OTA. It must include your name, address, daytime phone number, the FTB account number, the tax years involved, the specific amount you are disputing, and a clear statement explaining why you disagree with the FTB's decision. You must also attach a complete copy of the FTB notice you are appealing. Step 4: File the Appeal with the OTA You can file your appeal with the OTA in one of three ways. The easiest method for most people is online through the OTA's website at ota.ca.gov. You can also file by mail or fax to the addresses listed on the OTA website. Be sure to get proof of mailing or a fax confirmation. Important details and nuances: After you file, the OTA will process your appeal and set a schedule for both you and the FTB to submit written arguments and evidence. You have the right to request an oral hearing before a panel of three administrative law judges who will make the final decision. The OTA is an independent agency and is not part of the FTB. Warnings and limitations: The filing deadlines are not flexible. If you miss the deadline, the OTA will reject your appeal, and the FTB's decision will become final. While the OTA’s decision is binding on the FTB, you may have the right to challenge an unfavorable OTA decision by paying the tax and filing a lawsuit in superior court.
