Unless exempt under section 501, all domestic corporations must file an income tax return whether or not they have taxable income. Domestic corporations must file Form 1120, unless they are required, or elect to file a special return.

Generally, only a corporation files an 1120 form however, an LLC can file this form if it has filed Form 8832 to elect to be treated as an association taxable as a corporation.Corporations can generally electronically file Form 1120, related forms, schedules, and attachments. If there is a balance due, the corporation can authorize an electronic funds withdrawal while e-filing. The option to e-file does not, however, apply to certain returns.

  1. Gross receipts or sales.
  2. Cost of Goods Sold

Who signs this form?

The return must be signed and dated by one of the following officers: president, vice president, treasurer, assistant treasurer, chief accounting officer; or any other corporate officer (such as tax officer) authorized to sign. If an employee of the corporation completes Form 1120, the paid preparer space should remain blank. Anyone who prepares Form 1120 but does not charge the corporation should not complete this section. Generally, anyone who is paid to prepare the return must sign it and fill in the "Paid Preparer Use Only" area.

Returns and forms signed by a receiver or trustee in bankruptcy on behalf of a corporation must be accompanied by a copy of the order or instructions of the court authorizing signing of the return or form.
