Among the more elaborate business structures, a corporation is considered a legal entity with the power to sue, be sued, purchase property in its name, and enter contracts. While it is owned by its shareholders, it is also considered a separate entity that files its taxes and requires many formalities before its formation and during its existence. One of the most significant advantages of a corporation is the increased level of protection from liability that it provides its shareholders. Business owners can choose to begin a C-Corporation (that pays its own taxes) or an S-Corporation (a pass-through entity that requires shareholders to pay taxes on the business).
