Definition and Purpose of Form 1120-S

Form 1120-S is a tax document used by S corporations in the United States to report their financial activity to the Internal Revenue Service (IRS). It serves as the U.S. Income Tax Return for an S Corporation. This form allows these corporations, which elect to pass corporate income, losses, deductions, and credits through to their shareholders for federal tax purposes, to comply with tax regulations. By utilizing Form 1120-S, S corporations ensure proper reporting of their income and deductions, which are then allocated to shareholders as defined by their ownership stakes.

Who Typically Uses Form 1120-S

Typically, S corporations use Form 1120-S. An S corporation is a closely held corporation that has chosen to be taxed under Subchapter S of the Internal Revenue Code, thereby passing income and losses through to shareholders. Owners of S corporations must meet specific criteria, such as having 100 or fewer shareholders, all of whom must be U.S. citizens or residents. This form is crucial for businesses structured as S corporations, allowing them to report their income and distribute tax liabilities accordingly.

State-Specific Rules for Form 1120-S

• California: Requires S corporations to file Form 100S.
• New York: Requires S corporations to file Form CT-3-S.
• State Tax Treatment: Not all states recognize S corporation status; therefore, tax treatment might differ at the state level.
