I appreciate your time and effort to reply. I was wrong on the due date for the filing. The annual LLC tax is due on the 4th month. It was only the 100S income tax filing that was changed to become due one month earlier to the 3rd month of the S-corps tax year.
However, I do not see the exception you describe for not using the form #3522 for making the annual payment. It seems any LLC that has become a Califonia S-corp would meet the three criteria for using that form. The instructions also state "Do not use any other form for payment of the tax"
