What is a CA tax extension? A California tax extension grants a 6 months extension from the original tax due date.
Extension filers should file by Wednesday, Oct. 15, 2025. Taxpayers should file electronically and choose direct deposit for their tax refund its the fastest and safest way to receive their money. Taxpayers in disaster areas may have more time to file.
If you are not ready to file your state tax return by that date, you can get an automatic 6-month State of California tax extension and have until October 15 to file your return. California tax extensions require no form to be filed to apply for a state tax extension.
The Oct. 15, 2025, deadline applies to individual income tax returns and payments normally due on April 15, 2025.
State Income Tax (Franchise Tax Board) Use Payment Voucher for Automatic Extension for Individuals (PDF) (FTB 3519) if you owe tax and are unable to file your tax return by April 15. If you are residing or traveling abroad on April 15, California law allows you an additional two months to file your return.

Unlike the automatic six-month extension granted in April, the IRS typically does not offer further extensions beyond October 15 for personal tax returns. This deadline represents the absolute cutoff for most filers. Missing it can result in late-filing penalties and interest charges that accumulate over time.
Personal income tax. The due date to file your California state tax return and pay any balance due is April 15, 2025. However, California grants an automatic extension until October 15, 2025 to file your return, although your payment is still due by April 15, 2025.
Accordingly, certain deadlines falling on or after Jan. 7, 2025, and before Oct. 15, 2025, are postponed until Oct. 15, 2025. As a result, affected individuals and businesses will have until Oct. 15, 2025, to file returns and pay any taxes that were originally due during this period.
