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 S-corporation, C-corporation, or LLC, 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. Unlike a traditional corporation, operation as a professional corporation does not insulate a professional for personal liability for her own negligence or malpractice. The principal reason why groups of professions choose to organize as a professional corporation is that, unlike a general partnership, an owner is not personally liable for the negligence or malpractice of other owners.
