How Can I Get an Extension to File?


You automatically receive an extension to file through October 17.

If you can't file by April 18:

  • Refund — File your return by October 17. Choose e-file and direct deposit for the fastest refund.
  • Balance due — Pay the amount you owe by April 18 to avoid penalties and interest. You can pay online, by credit card, or by check with Form FTB 3519. Then file your return by October 17. Choose e-file to ensure we receive your return on time.
  • Not sure if you have a balance due? — Use the worksheet on form FTB 3519 to figure your tax.
