Deadline Relief for California Severe Winter Storms

The IRS has announced the postponement of certain tax-related deadlines for victims of severe winter storms, flooding, and mudslides in California. The tax relief postpones various tax filing deadlines that began on January 8, 2023. Affected individuals and households who reside or have a business in Colusa, El Dorado, Glenn, Humboldt, Los Angeles, Marin, Mariposa, Mendocino, Merced, Monterey, Napa, Orange, Placer, Riverside, Sacramento, San Bernardino, San Diego, San Joaquin, San Luis Obispo, San Mateo, Santa Barbara, Santa Clara, Santa Cruz, Solano, Sonoma, Stanislaus, Sutter, Tehama, Ventura, Yolo, and Yuba counties, as well as taxpayers with records located in the covered area that are needed to meet covered deadlines, qualify for relief.

In addition to extending certain tax filing and tax payment deadlines, the relief includes completion of many time-sensitive, tax-related acts described in IRS Revenue Procedure 2018-58 and Treasury Regulation 301.7508A-1(c)(1). Affected taxpayers with a covered deadline on or after January 8, 2023, and before May 15, 2023, will have until May 15, 2023, to complete the acts. This includes filing Form 5500 series returns that are required to be filed on or after January 8, 2023, and before May 15, 2023.


"Affected taxpayer" automatically includes any individuals who live, and businesses whose principal place of business is located, in the covered disaster area. Those who reside or have a business located outside the covered disaster area, but have been affected by the disaster, may contact the IRS to request relief.
