Today, October 16, 2023, the IRS issued an announcement, further postponing tax deadlines for most California taxpayers to November 16, 2023. Because of the last winter’s natural disasters, the normal April 15 due dates had previously been postponed to October 16. As a result, most individuals and businesses in California will now have until November 16 to file their 2022 returns and pay any tax due. Fifty-five of California’s 58 counties — all except Lassen, Modoc and Shasta counties — qualify for the extended deadline.

Eligible returns and payments include:

  • 2022 individual income tax returns and payments normally due on April 18.
  • For eligible taxpayers, 2022 contributions to IRAs and health savings accounts.
  • Quarterly estimated tax payments normally due on April 18, June 15 and Sept. 15.
  • Calendar-year 2022 partnership and S corporation returns normally due on March 15.
  • Calendar-year 2022 corporate and fiduciary income tax returns and payments normally due on April 18.
  • Quarterly payroll and excise tax returns normally due on May 1, July 31 and Oct. 31.
  • Calendar-year 2022 returns filed by tax-exempt organizations normally due on May 15.

However, please note, that the FTB (as of this moment) has not followed suit:  As of now, October 16 remains the due date for filing of California tax returns and payment of state taxes.
