The C corporation is the standard (or default) corporation under IRS rules. The S corporation is a corporation that has elected a special tax status with the IRS and therefore has some tax advantages. Both business structures get their names from the parts of the Internal Revenue Code that they are taxed under.
The IRS does not offer a standard form for changing your company's tax status from S corporation to C corporation. Instead, it simply requires a written statement be filed with the appropriate IRS service center, along with consent signed by a majority (more than 50%) of your corporation's shareholders.
We recommend converting to a C-Corp if a company wants to issue qualified small business stock and plans on selling its business in no less than five years.
Names of corporations must end with either the identifier "Incorporated" or "Corp." If one of these identifiers is present, then the company is most likely a corporation.
Because of the one-class-of-stock restriction, an S corporation cannot allocate losses or income to specific shareholders. Allocation of income and loss is governed by stock ownership, unlike partnerships or LLCs taxed as partnerships where the allocation can be set in the partnership agreement or operating agreement.
