General Instructions

Getting a California business tax extension depends on the type of business you’re filing for. All of California’s tax extensions are paperless, meaning there are no forms or applications to file. Note that sole proprietorships seeking a state extension should look to California’s personal tax extension guidelines instead.

Corporations

California corporation tax returns are due by the 15th day of the 3rd month following the end of the tax year (or March 15 for calendar year filers). A corporation can receive an automatic 7-month California tax extension as long as it is in “good standing” with the Franchise Tax Board and the California Secretary of State. No written request is necessary. The corporation must then file its return by the extended deadline (October 15 for calendar year taxpayers).

A tax extension does not give you more time to pay your state tax balance. If the corporation owes tax to the State of California, it is still due by the original deadline (March 15). You can make a state tax payment using Form FTB 3539 (Payment for Automatic Extension for Corporations and Exempt Organizations), found on Page 33 of California’s “Corporation Tax Booklet.”

General Partnerships, Limited Partnerships, and Limited Liability Partnerships

California partnership tax returns are due by the 15th day of the 4th month after the end of the tax year (or April 15 for calendar year filers). A partnership can automatically receive a 6-month state tax extension without having to submit a written request. A California tax extension moves the filing deadline to October 15 (for calendar year taxpayers).

A tax extension does not give you more time to pay your state tax balance. If the partnership owes tax to the State of California, it is still due by the original deadline (April 15). You can make a state tax payment using Form FTB 3538 (Payment for Automatic Extension for LPs, LLPs, and REMICs), found on Page 37 of California’s “Partnership Tax Booklet.”

Limited Liability Companies (LLCs)

California LLC tax returns are due by the 15th day of the 4th month following the end of the tax year (or April 15 for calendar year filers). An LLC can receive an automatic 6-month state tax extension as long as the LLC is not forfeited or suspended. A California tax extension will move the filing deadline to October 15 (for calendar year taxpayers).

A tax extension does not grant more time to pay state taxes. If the LLC owes tax to the State of California, it is still due by the original filing deadline (April 15). You can make a state tax payment using Form FTB 3537 (Payment for Automatic Extension for LLCs), found on Page 53 of California’s “Limited Liability Company Tax Booklet.”
