Yes, Californians, you have to register your non-CA LLC with CA.
I've seen this question asked almost daily on the boards: "I'm a California resident with an LLC formed in Ohio / Indiana / [insert-turnkey-haven-here] that holds my properties in that state. Do I have to register my LLC with the California Secretary of State and file a California tax return and pay the $800 LLC Tax every year?"
The answer is almost always YES since California considers the LLC as "doing business in California" and therefore required to do all the things mentioned in the first paragraph above if you, as a member of the LLC, do anything on the LLC's behalf while you are in California. Below are two excerpts from that I'm pretty sure indicts the whole lot of you!
I hope this clarifies the issue. Feel free to reach out with any questions.
