What is "professional corporation"

Professional corporations or professional service corporation (abbreviated as PC or PSC) are those corporate entities for which many corporation statutes make special provision, regulating the use of the corporate form by licensed professionals such as attorneys, architects, engineers, public accountants and physicians. The general category of the PC or PSC can be as a S-corporations, C-corporations or LLCs, but with subcategorization as a PC or PSC. Legal regulations applying to professional corporations typically differ in important ways from those applying to other corporations. Professional corporations, which may have a single director or multiple directors, do not usually afford that person or persons the same degree of limitation of liability as ordinary business corporations ( cf. LLP). Such corporations must identify themselves as professional corporations by including "PC" or "P.C." after the firm's name. Professional corporations often exist as part of a larger, more complicated, legal entity; for example, a law firm or medical practice might be organized as a partnership of several or many professional corporations.
