A Professional Limited Liability Company (usually shortened as PLLC, P.L.L.C., or P.L., sometimes PLC, standing for professional limited company - not to be confused with public limited company) is a limited liability company organized for the purpose of providing professional services. Usually, professions where the state requires a license to provide services, such as a doctor, chiropractor, lawyer, accountant, architect, landscape architect, or engineer, require the formation of a PLLC. However, some states, such as California, do not permit LLCs to engage in the practice of a licensed profession. Exact requirements of PLLCs vary from state to state. Typically, a PLLC's members must all be professionals practicing the same profession. In addition, the limitation of personal liability of members does not extend to professional malpractice claims.
A Series LLC is a special form of a Limited liability company that allows a single LLC to segregate its assets into separate series. For example, a series LLC that purchases separate pieces of real estate may put each in a separate series so if the lender forecloses on one piece of property, the others are not affected.
An L3C is a for-profit, social enterprise venture that has a stated goal of performing a socially beneficial purpose, not maximizing income. It is a hybrid structure that combines the legal and tax flexibility of a traditional LLC, the social benefits of a nonprofit organization, and the branding and market positioning advantages of a social enterprise.
An anonymous Limited Liability Company is a LLC for which ownership information is not made publicly available by the state. Anonymity is possible in states that do not require the public disclosure of legal ownership of a LLC, or where a LLC's identified legal owners are another anonymous company.
