I’m proud of you for asking such a clever question. Makes me wish the answer was just as thoughtful. Alas, it’s not: there’s no difference. A shareholder in a corporation, and a member in an LLC, are both nomenclature for defining owner. In fact, LLCs are flexible enough such that they can be structured to look like corporations, so their owners may also end up being “shareholders”. All that said, members in LLCs and shareholders in corporations are governed by different statutes, so their respective rights may differ.
