Foreign corporations can e-file their TY2007 1120-F returns by:

  1. Registering as a Large Taxpayer - Foreign corporations with U.S. citizen employees can designate a representative to register with e-services and create an e-file Application. The registration process, is a one-time, universal process that allows Large Taxpayers to do business with IRS electronically. The e-file Application for Large Taxpayers (pdf, 1.42MB) provides the Electronic Filing Identification Number (EFIN) and Electronic Transmitter Identification Number (ETIN) necessary to e-file a return with IRS.

  2. Using an Online Provider - Online Providers offer software, origination and transmission services. Online Providers who have successfully passed IRS' Assurance Testing System (ATS) are listed on at Corporate Returns. You may have to contact the Providers individually if they have not updated this link to indicate that they offer 1120-F software and services.

  3. Using a tax professional - Electronic Return Originators/Transmitters can originate and transmit returns to IRS. For a list of Providers who are EROs/Transmitters and who have passed IRS' ATS testing.

While e-filing Form 1120-F is not mandatory for Tax Year 2007, recently passed Treasury Directive 9363 extends the requirement to e-file to other corporate returns, including the 1120-F, for Tax Years ending on or after December 31, 2008 and beyond.

The 1120-F shares many business rules and forms/schedules currently used by Forms 1120/1120S.  IRS provides a complete list of the forms and schedules that can be attached, including the maximum number of forms that can be attached to the 1120-F return and the required format (XML or Portable Document Format [PDF]).
