The tax extension also applies to Californians who need to file federal business tax returns or make tax payments.

Gov. Gavin Newsom announced the tax extension in March.

“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,” Newsom said in a statement. “The state is aligning with the Biden Administration and extending the tax filing deadline in addition to the tax relief announced earlier this year.”
