Definition and Meaning of Form 1120S

Form 1120S is a tax return form utilized by S corporations to report income, gains, losses, deductions, and credits to the Internal Revenue Service (IRS). Unlike standard C corporations, S corporations are designed to avoid double taxation by passing corporate income, losses, deductions, and credits through to their shareholders. This means that shareholders report the income on their personal tax returns and pay taxes at their individual tax rates. As a result, the S corporation itself typically does not pay federal income tax.

The S corporation status can benefit small businesses by providing tax relief and simplifying taxation with single-layer taxation. Businesses must elect to be treated as S corporations by filing Form 2553, which must be approved by the IRS. Only eligible entities, such as domestic corporations and certain limited liability companies (LLCs), can elect for S corporation status. Furthermore, the shareholders must meet specific requirements, such as being U.S. citizens or residents and being limited in number.

Key Features of S Corporations

  • Pass-Through Taxation: Income is taxed at the shareholder level rather than at the corporate level.
  • Limited Liability: Shareholders are typically protected from personal liability for the debts of the corporation.
  • Single Level of Taxation: Avoids double taxation that C corporations face at both the corporate and personal levels.
  • Requirements for Eligibility: There are restrictions on the number and type of shareholders and only one class of stock is permitted.
