Personal identifiers

Corporation Internet Filing will ask you to provide the corporation's electronic signature with the following information on its online transmission form:

• Business Number
• Taxation Year End
• Corporation's assigned Web Access Code or EFILE On-Line number and password
• Path and name of the file containing your electronic corporation income tax return (".cor" extension)

Confirmation of receipt

After you fill in and send the Corporation Internet Filing online transmission form, we will do a preliminary check of your return. If it meets the basic requirements, we'll send you a confirmation number within seconds. This means that your tax return has been accepted for processing.

If there are any problems with the electronic tax return you sent us, we'll send you back an explanation of the errors or corrections needed. This means that your tax return was not accepted for processing. You should save, print, or note all messages we send. Before trying to retransmit the return, you must change the electronic version of the tax return by making the appropriate corrections according to the error messages you received. For information on making changes to an electronic tax return, see Corrections.

If your return has been accepted for processing, do not submit a paper copy of the return. After we have processed your return, we may need to contact you to obtain supporting documents, so remember to keep your receipts and information slips for at least six years. This is part of the same verification process that applies to all tax returns, whether paper or electronic.
