California Tax Extension

For Tax Year 2022, if you expect a refund or you don't owe taxes, you do not have to file a tax extension. However, if you believe you will owe taxes and can't file on time, you should take action. Here are the options available for California:

  • If you do not owe California income taxes by the tax deadline of April 18, 2023, you do not have to prepare and file a CA tax extension. In case you expect a CA tax refund, you will need to file or e-File your CA tax return in order to receive your tax refund money. 
  • If you owe CA income taxes, you will either have to submit a CA tax return or extension by the April 18, 2023 tax deadline in order to avoid late filing penalties. The extension will only avoid late filing penalties until Oct. 16, 2023. Note: Unless you pay all your Taxes or eFile your tax return by Oct. 16, 2023, the late filing penalties will start again after Oct. 16, 2023. You have the follow two options to file a CA tax extension:
    • Pay all or some of your California income taxes online via: California Web Pay or via Official Payments. Paying your CA taxes online on time will be considered a CA tax extension and you do not have to mail in Form FTB-3519.
    • Complete Form FTB-3519, include a Check or Money Order, and mail both to the address on Form FTB-3519.
    • Even if you filed an extension, you will still need to file your CA tax return either via eFile or by paper by Oct. 16, 2023.
  • Important: If you owe California and/or IRS income taxes and do not file an IRS and California tax return or extension by April 18, 2023, you will be subject to IRS and CA late filing penalties. Estimate IRS late filing, payment penalties. In addition, if you do not pay your taxes by April 18, 2023, you will be subject to late tax payment penalties. Filing an extension on time will ONLY eliminate the late filing penalties, but not the late tax payment penalties. Late filing penalties are generally higher than late payment penalties, so you should file something on time even if you can't pay anything on time!
