In a very last minute announcement, IRS has postponed the deadline for filing and paying 2022 tax returns for almost everyone in California from the previously established October 16 to November 16, 2023. This applies to everyone in Calif except three counties: Lassen, Modoc and Shasta.
As has long been its policy, the Calif Franchise Tax Board has announced that it is granting the same extra month postponement as IRS has.
