Professional corporation
Professional corporations or professional service corporations (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 lawyers, 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.
