If you have residency in a foreign country, living there full time, and have no other tax liability in California, then there is no obligation to pay CA state taxes.

Be aware that it’s generally not recommended to tell any of your US banking, investment, or credit card companies that you will be living full time overseas. Use a relative’s or friend’s address as a “home address” along with a virtual mailbox as a “mailing address”. Also keep some sort of US phone number that can receive text messages for banking verification needs. Letting the banks and investment firms know you live outside of the country may result in your accounts being shut down and could result in your foreign address ending up on your credit report making applying for a new US credit card or bank account difficult/impossible.
