If I filed my extension form 4868 and paid my estimate federal taxes, how do I file my CA state extension and pay my estimated state taxes?

California gives you an automatic filing extension to October 15, but if you owe, you must submit payment by April 18 to avoid penalties and interest. They offer 3 payment options:

1. Pay by bank account (Web Pay)
2. Pay by credit card
3. Print and mail Form FTB 3519 (3519-PIT) along with your check payment
