About the Corporation Internet Filing service

What do I require from CRA to file my T2 Corporation income tax return through the Internet?

To file your T2 Corporation income tax return directly to the CRA through the Internet, you require one of the following,

  • A Web Access Code - generally used if filing for one corporation; or
  • An EFILE number and password - generally used if filing tax returns for multiple corporations.

How to obtain a Web Access Code

If you transmit your T2 return using a Web Access Code, you can apply for, and receive, this code within certain commercial tax preparation software packages without having to call the Canada Revenue Agency’s Corporation Internet Filing Helpdesk.

Otherwise, contact the Corporation Internet Filing Helpdesk; please refer to the Helpdesk hours of service.

Alternatively, you may request Web Access Codes by fax. You must provide the corporation name, Business Number and Tax Year End. Send the request to the attention of the 'Corporation Internet Filing Help Desk' in Summerside at 902-432-5938 or Winnipeg at 204-984-0418.

How to obtain an EFILE online number and password

Complete the EFILE Registration online form if you are a tax professional and wish to use the Internet to file your client's Corporation income tax returns or you are responsible for filing multiple Corporation income tax returns (i.e. you are a corporate conglomerate). You must indicate during the EFILE registration process that you will be transmitting T2 returns. When you receive confirmation that you have successfully registered, you will be given an EFILE online number and password. Once you receive notification that you are certified for T1 EFILE, you will also automatically be certified for T2 EFILE and you can transmit Corporation income tax returns using your EFILE online number and password. For more information about EFILE registration, contact the EFILE Helpdesk.
