California Form 8879 – Fill Out and Use This PDF

California Form 8879 PDF Details

The California Form 8879 is issued by the California Franchise Tax Board (FTB). Its official title is the California e-file Signature Authorization for Individuals. Taxpayers use this form when an Electronic Return Originator (ERO) submits their state return to the FTB electronically on their behalf. The form applies specifically to filers who use the Practitioner PIN method for their California state tax return.

Under the Practitioner PIN method, you select a five-digit PIN that acts as your electronic signature. Your ERO enters that PIN when transmitting your return. You do not need to mail any paper documents to the FTB. Both you and your ERO must sign Part III of the form before the return is transmitted. You should keep a copy of the signed form for at least three years after the filing date.

Parts of California Form 8879: The form is divided into three main sections. Part I captures identifying information, including your name, Social Security number, adjusted gross income (AGI), and any refund or balance due amount shown on your return. Part II contains the taxpayer declaration, where you confirm the accuracy of your return and authorize the use of your PIN as your legal signature. Part III is the ERO Certification section. Your tax preparer enters their firm name, their six-digit Electronic Filing Identification Number (EFIN), and their PIN. If you are filing jointly with a spouse or Registered Domestic Partner (RDP), each person must provide a separate five-digit PIN entry in Part I.

California Form 8879 versus FTB 8453: Not all California e-filers use Form 8879. If your ERO does not use the Practitioner PIN method, they will use FTB 8453 instead. FTB 8453 requires you to physically sign the form, which your ERO then retains on file. Ask your tax preparer which form applies to your return before you begin. If you are also filing a federal return electronically, your preparer uses a separate document, the IRS Form 8879, for the federal filing. The California state form and the federal form are separate documents even though they serve the same purpose.

Bank authorization and refunds: Taxpayers who plan to pay a balance due by electronic funds withdrawal must enter bank routing and account information in Part I. This authorizes the FTB to debit your bank account on the payment date you choose. If you expect a refund, the deposit details come from your California Form 540 return, not from Form 8879 itself. Form 8879 is strictly an authorization document. It does not replace your income tax return or any payment voucher.

Tax year and version notes: The FTB issues updated versions of Form 8879 each year. Make sure you are using the version that matches the tax year you are filing. For example, a 2024 California return requires the 2024 version of the form. Older versions of the form should not be used for current-year filings. If you are unsure which version your ERO is using, ask them to confirm before you sign. You may also encounter a related form called FTB 8879-PMT, which covers electronic authorization specifically for estimated tax payments. That form is distinct from the standard individual e-file authorization form covered here.
