Corporation Internet Filing - General

The Corporation Internet Filing option was developed to offer clients a convenient affordable filing option. By adopting this option the CRA is demonstrating its commitment to the Government Online Initiative.

All corporations with gross revenue in excess of $ 1 million and filing a return with tax year ending in 2010 and subsequent will be required to Internet file their return using the CIF service with the exception of:

  • non-resident corporations;
  • insurance corporations;
  • corporations reporting in functional currency; and
  • corporations those are exempt from tax under section 149 of the Income Tax Act.


The gross revenue in excess of $ 1 million will be determined by the total of lines 1258299, Total revenue and 1259659, Total farm revenue.

The Internet filing process is described in detail on the CRA`s Web site at We recommend you review instruction prior to beginning the internet filing procedure.

Return T183 - Mandatory

T183, Information Return for Corporations Filing Electronically, is the certification form, which must be completed when electronically filing a T2 return. This form is located in the Federal Tab and can be completed on line then printed. The form is not filed with the electronic return, but maintained by the corporation and the person who files the tax return over the Internet.

Part F of Form T183 must be completed in duplicate and signed by the taxpayer, or the person who is required to file the return under the Income Tax Act (examples: Trustee in Bankruptcy or Legal Representative), before the return is transmitted.

The form is year specific and only the current year version is acceptable.

Note: The use of signature labels on Form T183 is not acceptable. A signature other than the taxpayer's, the Trustee's, or the Legal Representative's, is acceptable as long as an applicable power of attorney exists.

The entries entered on Form T183 must accurately reflect the entries on the electronic return. If the return is not accepted as originally transmitted, and the changes required for re-transmission alter the refund or balance owing by more than $300, a new Form T183 must be completed and signed.

Part H - Document Control Number (DCN)

EFILE software generates a Document Control Number at the time a record is created. Record this DCN in Part H. In addition, for each EFILE Online return accepted, the system generates a confirmation number. This confirmation number should also be recorded in Part H of the form.


As required by subsection 150.1(4) of the Income Tax Act, both you and your client have to keep a copy of the completed Form T183. Do not to submit the form unless CRA asks for it. Keep your copy in a secure location.

Form T183 must be kept for at least six years following the date that the return was filed. Written permission is required for you or your client to destroy Form T183 before the six-year period is up. For more information, see Information Circular IC78-10R5, Books and Records Retention/Destruction.

CRA will periodically monitor Form T183 and will ask you for completed copies. If you fail to provide these completed forms when asked for them, CRA may suspend your electronic filing privileges.

Amended Federal Return and T2 Bar Code Return (T2 BCR)

As of October 2012, CRA can capture the information from an amended return in the T2 BCR format. An amended T2 BCR cannot be used to change the following information:

  • 200010: Head office address change
  • 200020: Mailing address change
  • 200030: Location of books and records change
  • 200910, 200914 and 200918: Direct deposit information
  • 200990: Language of correspondence

To identify an amended T2 Return, line 200997 (Amended return indicator) and line 200996 (Description of changes) must be used on Schedule 200, Page 1 and be part of the amended T2 BCR.

If the amended return indicator is 1 (Yes) at line 200997:

  • a relevant description of changes is mandatory at line 200996, and
  • letter A must be printed on the first page of the T2 BCR.

The amended T2 BCR must include all returns and schedules, i.e. not only the returns and schedules revised.

All schedules included in the amended T2 BCR are considered as amended. This means data from amended schedules will overlay the previous data.

Example 1 - Lines/rows not included in a schedule of the amended T2 BCR but existed previously. Even if the intention of the request is to simply increase the revenue on one of the Schedule 125 revenue lines, the entire Schedule 125 will have to be completed and included in the amended T2 BCR. If only the increase is completed, the new Schedule 125 included in the amended T2 BCR will be considered to have only one entry.

Note: Same process if a row existed previously but no longer exists on the schedule in the amended T2 BCR.

Example 2 - Schedule not included in the amended T2 BCR but existed previously. If a schedule was filed previously for example, in the initial return and is not included with the amended T2 BCR, this schedule won`t be considered.

Example 3 - Combination of example 1 and 2: For looping schedules as Schedule 125, if there is only one existing Schedule 125, the new Schedule 125 includes in the amended T2 BCR will replace the existing one. If there are three existing Schedule 125 and only one new Schedule 125 is included in the amended T2 BCR, the new Schedule 125 will become Schedule 125 sequence-1 and the existing Schedule 125 sequence-2 and 125 sequence-3 won`t be considered.
