In California, taxpayers who are unable to file their state income tax returns by the original due date can request an extension of time to file. The extension allows taxpayers to file their tax returns up to six months after the original due date.

To request an extension, taxpayers must complete and file California Form FTB 3519, which can be obtained from the California Tax Extension 2023. The form must be filed by the original due date of the tax return, which is usually April 15th of each year.

It is important to note that an extension of time to file does not extend the time to pay any tax due. Taxpayers must estimate their tax liability and pay any amount owed by the original due date to avoid penalties and interest.

I recommend checking the California Franchise Tax Board's website closer to the tax season in 2023 for updated information regarding tax extensions and deadlines for that year.
