That's a good question... the last couple of LLCs that I've formed have been for businesses that are clearly operating in CA (one was for real estate here and the other for a local service company) and thus require the LLC there. Since I'm selling to the whole US here, maybe it is a better option... I will look into it.
Lawyer here. Not yours. But consider Delaware or really any state. You do not need to form it in CA just because that’s where you are. Just get a registered agent and pick a state that doesn’t have oppressive LLC fees...
Why an LLC instead of an S-corp?
