Whenever a partner or sole proprietor dies, the business also ceases. In a similar fashion, whenever a new partner is added or a partner wants to leave, a new partnership must be formed. This is not the case with the corporate form. If someone wants to become an owner of a corporation, then that person buys stock. Sale of stock transfers ownership from seller to buyer.
Stockholders can come and go without affecting the legal status or operations of the firm.
Moreover, if the corporation needs money to expand its operations or pay off debt, funds can usually be raised by selling additional stock. This is not exactly the case, but there are some similarities. Your accountant should be in a good position to identify the merits of forming your business as a Sub S corporation. The Sub S type of corporation does not pay a federal corporate income tax. In a regular corporation, the firm pays a federal tax on its profits and the stockholders pay tax only on the dividends they receive.
