I'm snail mailing form FTB 3522 and payment to the State of California Franchise Tax Board today. It is the annual $800 tax for all LLCs doing business in Calfornia. Any new business must pay the fee by the 15th day of the 4th month, or by April 15, 2008 for an existing LLC.
This is a very simple process and one that could have been easily been done online, without having to print out a form, write a check, stuff and stamp an envelope and trudge to the nearest post box. Technology people, let's use it!
