Like a C corporation, an S corporation is generally a corporation under the law of the state in which the entity is organized. However, with modern incorporation statutes making the establishment of a corporation relatively easy, firms that might traditionally have been run as partnerships or sole proprietorships are often run as corporations with a small number of shareholders in order to take advantage of the beneficial features of the corporate form; this is particularly true of firms established prior to the advent of the modern limited liability company. Therefore, taxation of S corporations resembles that of partnerships.
