A licensed professional needs to incorporate their business as either a professional limited liability company (PLLC) or a professional corporation (PC). What does it mean to incorporate as a professional LLC or a professional corporation? Much like an LLC, a professional LLC (PLLC) also separates personal and professional assets with limited liability protection. A professional corporation is designed to protect licensed professionals and their personal assets. Those associates that have not incorporated as a professional corporation do not receive the same type of protection.
