When do I have to pay the Annual California LLC Tax?

The annual LLC tax is due and payable on or before the 15th day of the 4th month after the beginning of the LLC’s taxable year (fiscal year) or April 16, 2001 (calendar year). The first taxable year of an LLC that was not previously in existence begins when the LLC is organized. For example, if the Articles are filed on June 1, 2001, the annual LLC tax is due on September 15, 2001.
