IIRC it is generally preferable to incorporate in DE for dispute resolution but doing so does not exempt you from paying CA taxes & fees. You will still need to pay the minimum tax amount if you are doing business in CA.
Yes this is correct. I have an LLC in Nevada and I still have to register an LLC in California because I live and work here. It's a foreign LLC entity.
Could you expand on that?
I really don't understand.
In this case, a foreign entity is an LLC that is registered in another state, but does enough business in CA to require registering in CA. In this case you register as a "foreign entity".
If you get to the point of having more than 50% of your employees outside of CA, I believe you can avoid registering as a foreign entity.
