From the Governor's announcement:
To help alleviate some of the hardship many have endured during this trying period, the FTB has extended the filing and payment deadlines for individuals and businesses in California until October 16, 2023.
This relief applies to deadlines falling on or after January 8, 2023, and before October 16, 2023, including the 2022 individual income tax returns due on April 18 and the quarterly estimated tax payments, typically due on January 17, 2023 and April 18, 2023. Those payments were previously extended to May 15, 2023 for those impacted by winter storms.
