Corporation

A corporation is an artificial person or legal entity managed by a board of directors, consisting of one or more individuals, who collectively elect officers to run the corporation’s day-to-day business activities. There are two types of corporations in Virginia, stock corporations, which are authorized to issue shares to persons who become shareholders, the owners of the corporation, and nonstock corporations, which may have members, but not owners. Stock corporations are usually formed to generate a profit for the shareholders. Nonstock corporations are usually organized for not-for-profit purposes, such as a tax-exempt, charitable organization or a property owners’ association. Generally, officers, directors, shareholders and members are not liable for the obligations of the corporation.

Limited Liability Company

A limited liability company is an unincorporated association of one or more members (the owners) who share in the profits and losses of the company’s business. It is managed in accordance with an operating agreement by one or more members (member-managed) or by one or more managers (manager-managed). A limited liability company is a separate legal entity and, generally, the members and managers are not liable for the obligations of the limited liability company.
