"S" Corporation

S corporations are corporations that elect to pass corporate income, losses, deductions, and credits through to their shareholders for federal tax purposes.

Shareholders of S corporations report the flow-through of income and losses on their personal tax returns and are assessed tax at their individual income tax rates. This allows S corporations to avoid double taxation on the corporate income. S corporations are responsible for tax on certain built-in gains and passive income at the entity level.

To qualify for S corporation status, the corporation must meet the following requirements:

  • Be a domestic corporation
  • Have only allowable shareholders
    • May be individuals, certain trusts, and estates and
    • May not be partnerships, corporations or non-resident alien shareholders
  • Have no more than 100 shareholders
  • Have only one class of stock
  • Not be an ineligible corporation (i.e. certain financial institutions, insurance companies, and domestic international sales corporations).

In order to become an S corporation, the corporation must submit Form 2553 Election by a Small Business Corporation (PDF) signed by all the shareholders. See the Instructions for Form 2553 (PDF) for all required information and to determine where to file the form.
