FAQ / What is e-file for large and mid-size corporations?

IRS e-file is the name for the electronic filing of tax returns. When a corporation e-files they send their income tax return data to IRS electronically instead of on paper forms. In 2004 IRS started a new e-file system for corporations, referred to as “Modernized e-file” (MeF) that is web-based, allowing electronic filing of corporate income tax returns through the Internet. MeF uses the widely accepted XML format, a standardized way of identifying, storing and transmitting data.

Certain corporations are required to e-file as explained in these FAQs. With few exceptions, all corporations that file Forms 1120, 1120S, or 1120-F may file electronically.

IRS e-file is available to corporations that prepare and/or transmit their own returns and to those that rely upon a tax professional to prepare and/or transmit their returns.
