When to File California State Taxes
California state tax returns are due the same day as federal returns—typically April 15. Extensions are available until October 15, but any tax owed must still be paid by April 15 to avoid penalties.
California Residency and Tax
You're a California resident for tax purposes if:
- You're domiciled in California (permanent home)
- You spend more than 9 months of the year in California
- You maintain a California driver's license, voter registration, or business
California aggressively audits residents who claim to have moved out of state. If you earned income while a CA resident, you owe CA tax even if you later moved.
