if a corporation is formed then the owners are known as
Corporation Where local law distinguishes corporations by the ability to issue stock, corporations allowed to do so are referred to as "stock corporations", ownership of the corporation is through stock, and owners of stock are referred to as "stockholders" or "shareholders". Corporations not allowed to issue stock are referred to as "non-stock" corporations; those who are considered the owners of a non-stock corporation are persons (or other entities) who have obtained membership in the corporation and are referred to as a "member" of the corporation.
Limited company In the United States, corporations have limited liability and the expression corporation is preferred to limited company. A "limited liability company" (LLC) is a different entity. However, some states permit corporations to have the designation Ltd.[7] (instead of the usual Inc.) to signify their corporate status. A Limited company must file annual tax returns ("corporation" tax returns) with the Securities and Exchange Commission.
