How do I change my mailing address on file with the California Franchise Tax Board?

You can change your mailing address with the California Franchise Tax Board (FTB) online, by mail, or on your annual state tax return. The fastest and most reliable method is to use your MyFTB online account. Here are the steps to formally change your address: Step 1: Choose the Best Method for You You have three primary options: using the FTB's online portal (MyFTB), mailing a specific form (Form 3533), or updating your address when you file your next tax return. Your choice depends on your urgency and access to the internet. Step 2: Use MyFTB for the Fastest Update The quickest way is to log into your MyFTB account at ftb.ca.gov. If you do not have an account, you can create one. You will need your Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN) and information from a previously filed California tax return (Form 540) to verify your identity. Once logged in, navigate to your profile settings to update your address. Step 3: Mail Form 3533, Change of Address If you cannot use MyFTB, download Form 3533, Change of Address for Individuals, from the FTB website. Complete the form with your name, SSN or ITIN, old address, and new address. You must sign the form. Mail the completed form to: Franchise Tax Board, PO Box 942840, Sacramento, CA 94240-0002. Step 4: Update Your Address on Your Tax Return If you are about to file your annual California tax return, you can simply enter your new mailing address in the designated section of the form (e.g., Form 540). Be aware this method is the slowest, as the FTB will not process the change until it processes your entire return. Important details and nuances: The FTB sends all official notices, including deficiency assessments and collection actions, to your "last known address" on file, as per California Revenue and Taxation Code Section 19032. Failing to receive a notice because your address is outdated is not a valid excuse. Informing the U.S. Postal Service, the DMV, or the IRS of your move does not update your address with the FTB; you must contact them directly. Warnings and limitations: We strongly recommend using MyFTB or Form 3533 instead of waiting to file your next tax return. Relying on your tax return can cause significant delays in receiving important correspondence or your tax refund. Due to strict privacy laws (R&TC § 19542), the FTB will not change your address over the phone. This is general information and does not constitute legal advice. For complex situations, such as if you are in a dispute with the FTB or have a business entity, consult with a qualified California attorney.
