LLCs and S-Corps also differ greatly in terms of how they are managed. LLCs can be managed by either their owners or designated managers. S-Corps, on the other hand, are required to have a board of directors and corporate officers, such as a CEO, CFO, and CMO. S-Corps are also legally required to adopt corporate bylaws, conduct initial and annual shareholder meetings, produce company meeting minutes, and follow extensive stock issuing regulations.
