Warning: there's a really important point missing from this list - pay taxes in California. There's a minimum "Franchise Tax" of $800 plus a percentage of California-derived revenue. All entities doing business in California (be that selling to customers based there or having employees there) must register with the state and pay this. The first year is free though - the minimum is waived.
