California has an automatic six month extension for individual tax returns.
We give you an automatic 6-month extension to file your return. You must file by the deadline to avoid a late filing penalty.
The deadline is October 15, 2025.
An extension to file your tax return is not an extension to pay. Pay the amount you owe by April 15, 2025 to avoid penalties and interest.
