IRS and California Extend Tax Filing Deadlines


Both the IRS and the State of California extended the tax filing deadline for Californians impacted by December and January winter storms to October 16, 2023.


Individuals whose principal residence is located in, and businesses whose principal place of business is located in, Alameda, Alpine, Amador, Butte, Calaveras, Colusa, Contra Costa, Del Norte, El Dorado, Fresno, Glenn, Humboldt, Inyo, Kings, Lake, Los Angeles, Madera, Marin, Mariposa, Mendocino, Merced, Mono, Monterey, Napa, Nevada, Orange, Placer, Riverside, Sacramento, San Benito, San Bernardino, San Diego, San Francisco, San Joaquin, San Luis Obispo, San Mateo, Santa Barbara, Santa Clara, Santa Cruz, Siskiyou, Solano, Sonoma, Stanislaus, Sutter, Tehama, Trinity, Tulare, Tuolumne, Ventura, Yolo, and Yuba counties are eligible for tax relief (affected taxpayers).


To help alleviate some of the hardship many have endured during this trying period, the IRS and CA FTB extended the filing and payment deadlines for affected taxpayers in California until October 16, 2023. This relief applies to deadlines falling on or after January 8, 2023, and before October 16, 2023, which includes:

  • Individuals whose tax returns and payments are due on April 18, 2023.
  • Quarterly estimated tax payments due January 17, 2023, April 18, 2023, June 15, 2023, and September 15, 2023.
  • Business entities whose tax returns are normally due on March 15 and April 18.
  • CA Pass Through Entity Elective Tax payments due on June 15, 2023.
  • Estate, Trust, and Gift tax returns and payments.
  • Tax-exempt entities.


Please note that if you file tax returns in states other than California, which has conformed with the IRS extended tax deadline to October 16, 2023, then we still need to file your other state returns by the original state deadlines or obtain an extension. In addition, any tax payments due on income from other states will need to be paid on or before the original due dates. In most cases, this will require that your federal return be finalized so that we can file an accurate state tax return or have enough work done on the federal return to prepare an accurate state extension. While not covered in this discussion, the IRS has granted similar relief for parts of Alabama and Georgia.
