California grants an automatic 6 months extension of time to file a state income tax return if you are granted for Federal Tax Extension. So there are no forms required to file for California state extension. However, if you owe taxes you must then pay the taxes by due date to avoid penalties. If you are due for refund then file your return by October 15.

If you have balance due, pay the amount you owe before the deadline to avoid penalties and interest. For most Businesses it is March 16 whereas for Individuals, it is April 15. If you are not sure about your balance due then use the worksheet on form FTB 3519/FTB 3539 to figure your tax.

What is the due date to apply for automatic extension?

March 16.

Do I need to file a California state extension form in addition to my federal extension?

No. If you were approved for a federal tax extension, the State of California will automatically grant you a 6 month tax extension.

If I file an extension, will I get an extension for paying the taxes I owe?

No. Extension is granted only for filing the returns. The payment has to be made before the due date to avoid penalties.

Is there any penalty involved if I miss the due date?

Yes. If the corporation or exempt organization fails to pay its total tax liability by the original due date, the corporation or exempt organization will incur a late payment penalty plus interest. The FTB may waive the late payment penalty based on reasonable cause. Reasonable cause is presumed when 90% of the tax shown on the return, but not less than minimum franchise tax if applicable, is paid by the original due date of the return. However, the imposition of interest is mandatory.

If the corporation or exempt organization does not file its CA tax return by the extended due date, or the corporation's powers, rights, and privileges have been suspended or forfeited by the FTB or the California SOS, as of the original due date, the automatic extension will not apply and a delinquency penalty plus interest will be assessed from the original due date of the CA tax return.If the corporation or exempt organization is required to remit all of its payments electronically and pays by another method, a 10% non-compliance penalty will be assessed.
