Key California Tax Deadlines for 2025

For most individuals and businesses in California, the tax filing year mirrors the federal tax calendar. However, there are some unique state-specific dates that you need to be aware of. Here are the most important tax filing deadlines in California for 2025:

  1. Personal Income Tax Filing Deadline
    The deadline to file your California state income taxes for the year 2024 is April 15, 2025. If this date falls on a weekend or holiday, it’s typically extended to the next business day. It’s important to file by this date to avoid late fees and interest charges.
  2. Extension Request Deadline
    If you can’t file by the April 15 deadline, you can request a tax extension. The California Franchise Tax Board (FTB) grants a six-month extension, giving you until October 15, 2025 to file your return. However, keep in mind that an extension does not extend the time to pay any taxes due.
  3. Quarterly Estimated Tax Payments
    If you are self-employed or have income that is not subject to withholding, you may be required to make quarterly estimated tax payments to avoid penalties. Here are the deadlines for 2025:
    • 1st Quarter: April 15, 2025
    • 2nd Quarter: June 15, 2025
    • 3rd Quarter: September 15, 2025
    • 4th Quarter: January 15, 2026
  4. Business Tax Filing Deadlines
    Businesses operating in California must adhere to specific tax deadlines, including for sales tax returns, payroll taxes, and corporate income taxes. Generally, corporate tax returns are due by March 15, 2025, unless an extension is filed. Be sure to check the specific requirements for your business type.

2025 Tax Calendar: Important Dates to Keep in Mind

  • January 31, 2025: Deadline for employers to provide employees with their W-2 forms and for businesses to send out certain tax forms (e.g., 1099).
  • March 15, 2025: Deadline for S corporations, LLCs, and partnerships to file their 2024 income tax returns.
  • April 15, 2025: Final deadline for filing individual and business tax returns (unless extended) for the year 2024.
  • October 15, 2025: Final deadline for filing extended individual returns.
