IRS Announces Tax Extension for California Filers: What You Need to Know

Read the Article

Update: October 16, 2023: The IRS today further postponed federal tax deadlines for most California taxpayers to November 16, 2023. Fifty-five of California’s 58 counties – all except Lassen, Modoc, and Shasta counties – qualify for relief due to three different FEMA disaster declarations over a period of several months. The California Franchise Tax Board confirmed that tax filers living in the covered disaster areas have until November 16, 2023 to file and pay their state tax year 2022 taxes in alignment with the extended federal tax deadline.

Residents and businesses located in the counties listed as covered disaster areas in the IRS January 10 announcement, IRS January 24 announcement, and IRS March 17 announcement are eligible for the extended tax relief. The postponement of time to file and pay does not apply to residents and businesses located in Lassen, Modoc, and Shasta.

Update: June 7, 2023: The IRS apologizes to California taxpayers for any confusion caused by balance due mailings, Notice CP14, sent out as a legal requirement. While the letter states that taxpayers need to pay in 21 days, most California taxpayers have until later this year to pay under the disaster declaration. Taxpayers who have received these letters do not need to call the IRS and the disaster dates remain in effect. 

These past few weeks severe winter storms, flooding, and mudslides have ravaged parts of California leaving many without power and in a state of disaster.  If you were impacted by these storms we want you to know TurboTax is here for you, and we want to keep you up to date with important tax relief information that may help you in this time of need.

The Federal Emergency Management Agency (FEMA) declared the recent events as a disaster, and the IRS announced that victims of these California storms have until November 16, 2023, to file various individual and business tax returns and make certain tax payments. Currently tax relief is available to any area designated by FEMA. This means that individuals and households that reside or have a business in Alameda, Contra Costa, Colusa, El Dorado, Fresno, Glenn, Humboldt, Kings, Lake, Los Angeles, Madera, Marin, Mariposa, Mendocino, Merced,  Modoc, Mono, Monterey, Napa, Orange, Placer, Riverside, Sacramento, San Benito, San Bernardino, San Diego, San Joaquin, San Luis Obispo, San Mateo, Santa Barbara, Santa Clara, Santa Cruz, Shasta, Solano, Sonoma, Stanislaus, Sutter, Tehama, Tulare Ventura, Yolo and Yuba counties qualify for tax relief. Taxpayers in certain storm impacted localities designated by FEMA will automatically receive the same filing and payment relief.  The current list of eligible localities is available on the disaster relief page on

What are the extended tax and payment deadlines for victims of California storms?

The tax relief postpones various tax filing and payment deadlines that occurred based on three different FEMA disaster declarations covering severe winter storms, flooding, landslides, and mudslides over a period of several months. . As a result, affected individuals and businesses will have until November 16, 2023 to file returns and pay any taxes that were originally due during this period. These include:

  • 2022 Individual and Business Returns: Individual income tax returns and various business returns normally due on March 15 and April 18, 2023 will now have until November 16, 2023 to file their 2022 return and pay any tax due. Among other things, this means that eligible taxpayers will have until November 16 to make 2022 contributions to their IRAs and health savings accounts.
  • Quarterly Estimated Tax Payment: Tax Year 2022 4th quarter estimated tax payment with a deadline of January 17, 2023 and Tax Year 2023 estimated tax payments normally due April 18, June 15 and Sept. 15 have been extended until November 16, 2023. This means that individual taxpayers can skip making the fourth quarter estimated tax payment, normally due January 17, 2023, and instead include it with the 2022 return they file, on or before November 16.
  • Quarterly Payroll and Excise Tax Returns: Quarterly payroll and excise tax returns that are normally due on May 1, July 31, and October 31 are also extended until November 16, 2023. In addition, penalties on payroll and excise tax deposits due on or after January 8, 2023 and before January 23, 2023 will be abated as long as the deposits were made by January 23, 2023. 

What do I need to do to claim the tax extension? 

The IRS automatically provides filing and penalty relief to any taxpayer with an IRS address of record located in the disaster area. Taxpayers do not need to contact the IRS to get this relief. However, if an affected taxpayer receives a late filing or late payment penalty notice from the IRS that has an original or extended filing, payment or deposit due date falling within the postponement period, the taxpayer should call the number on the notice to have the penalty abated.

The current list of eligible localities is always available on the disaster relief page on

Is there an extension for the California state tax return? 

California has announced that taxpayers and business owners affected by the recent winter storms in California qualify for an extension to file and pay taxes until November 16, 2023. 

Do surrounding areas outside of California qualify for an extension? 

The IRS will work with any taxpayer who lives outside the disaster area but whose records necessary to meet a deadline occurring during the postponement period are located in the affected area. Taxpayers qualifying for relief who live outside the disaster area need to contact the IRS at 866-562-5227. This also includes workers, assisting the relief activities, who are affiliated with a recognized government or philanthropic organization.

How can I claim a casualty and property loss on my taxes if impacted?

Individuals or businesses who suffered uninsured or unreimbursed disaster-related casualty losses can choose to claim them on either the tax return for the year the loss occurred (2023 return normally filed next year in this instance) or the loss can be deducted on the tax return for the prior year (2022, normally filed this tax season). Individuals may also deduct personal property losses that are not covered by insurance or other reimbursements. 

If you are claiming the disaster loss on your tax return be sure to write the Disaster Designation, “California, severe winter storms, flooding, landslides and mudslides“, in bold letters at the top of the form. 

Also be sure to include the following FEMA declaration number on any return claiming a loss:  

  • March 9, 2023 severe winter storms, flooding, landslides and mudslides: 
    • Be sure to include the FEMA disaster declaration number, FEMA-3592-EM, on any return.
  • Dec. 27, 2022 severe winter storms, flooding, landslides, and mudslides:
    • Be sure to include the FEMA disaster declaration number, FEMA-4683-DR, on any return. 
  • Jan. 8, 2023 severe winter storms, flooring, and mudslides: 
    • Be sure to include the FEMA disaster declaration number, FEMA-3591-EM, on any return.

The tax relief is part of a coordinated federal response to the damage caused by the harsh storms and is based on local damage assessments by FEMA. For information on disaster recovery, visit
