Family Holding Company Structured as General Partnership

[Henry Thai]

My siblings and I want to pool our savings together to invest with a syndicate. We are thinking about setting up a holding company structured as a general partnership instead of a LLC to avoid California taxes and fees. But, will one of the partners have to pay self-employment tax?

Also, we plan to use this holding company for future investments, but do not intend to keep the same partners split. Could we use the same holding company? Or would it be easier to just start another one?

Thanks in advance to anybody who has any insight to my questions above!
