SACRAMENTO – In addition to tax relief measures that Governor Gavin Newsom announced in January, California is also extending the state tax filing and payment due dates to October 16, 2023 for Californians impacted by the winter storms in December and January. This aligns California with the Biden Administration, which announced that the IRS extended various due dates until October 16, as well.

“As communities across the state continue recovering from the damage caused by the winter storms, California is working swiftly to help recovering Californians get back on their feet,” said Governor Newsom. “The state is aligning with the Biden Administration and extending the tax filing deadline in addition to the tax relief announced earlier this year.”

Last month, Governor Newsom announced tax relief for those impacted by winter storms, giving people the ability to claim a deduction for disaster loss and extending certain filing deadlines.

The following counties are eligible for this extended tax relief, per the IRS announcements here and here:

Residents and businesses 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 who have been affected by severe winter storms, flooding, landslides, and mudslides are eligible for tax relief.
