Attaching documents for EFILE of T2 returns with the Attach a Doc feature

Frequently Asked Questions about attachments

What modules allow electronic transmission of attachments in ProFile?

The existing ProFile feature “HyperDocs” exists in all modules for users to add attachments. Currently only the T2 module allows transmission of attachments via the “Attach a Doc” feature.

When are attachments transmitted?

CRA allows corporations to transmit supporting documentation via ProFile’s “Attach a Doc” feature within 24 hours of the EFILE of a T2’s initial or amended return.

What files types are supported?

The following file types can be used as attachments:

  • .pdf
  • .doc
  • .docx
  • .xls
  • .xlsx
  • .rtf
  • .txt
  • .jpg
  • .jpeg
  • .tiff
  • .tif
  • .xps

What is the maximum attachment size?

The maximum attachment size is 150 megabytes (MB); this is a CRA limitation.

Is there a limit to the number of attachments transmitted?

Provided the attachments are transmitted within 24 hours of EFILE of the T2 return, there are no limitations to the number of attachments that can be transmitted.

Can I make attachments prior to the T2 return being transmitted?

Yes, but the T2 return must be transmitted first, before the attachments.

To learn more, please review our tutorial video. The Attach a Doc content begins at 28:07 of the video:

There are two methods to start attaching documents: from the right-click menu in a T2 return or from the ProFile top toolbar.

From the right-click menu:

1.  Open the T2 return.

2. Right-click on the return or field.

3. Select the “Attach a Doc” option from the menu:


The attachment wizard displays.

From the ProFile toolbar:

4. Select the “Attach a Doc…” option from the “EFILE” menu in the top toolbar:


The attachment wizard displays.

The attachment wizard provides the ability to attach documents to a previously transmitted T2 return:


1. Click the “Browse” button; the browse window displays:


2. Navigate to the location of the file and select it.

3. Click the “OK” button; the “Attach a file to return” window displays with the file path and name of the document being attached:


4. Select the “Document type”; the list pre-populates with document types accepted by CRA for transmission. Start typing to see options or scroll down the list and make the selection:


5. Enter a brief description in the “Description” field; this is a mandatory field to meet CRA requirements.

6. Click the “Save” button.

The attachment wizard accepts the document and lists the “NAME”, “DOCUMENT TYPE”, and “STATUS” values:


7. Use the “ACTIONS” icons to preview, delete, or edit the attachment description, if needed:


An attachment that fails to meet the requirements for transmission displays in red text:


Errors must be addressed prior to re-saving the window. Errors can include, but are not limited to:

  • special characters in the file name
  • failure to enter a description of the attachment
  • the file was moved or deleted since being attached

See the section “Troubleshooting attachment issues” below for error examples and resolutions.

1. Ensure all relevant files are included in the “Add attachments” tab of the attachment wizard.

2. Click the “Transmit attachments to CRA” button:


The “Transmit attachment(s) to CRA” window displays:


3. Select EFILE number and password or Web Access Code (WAC) as the method of transmission. If you require a WAC but do not have one, select the “I want to request a Web Access code and transmit the attachment(s)” option.

4. Click the “Decline” button to end the transmission process. The attachment remains in the “Add attachment(s)” pane until submitted or deleted.

5. Click the “Accept” button to transmit; the “Transmitting attachment(s)” window displays:


Note: do not close the “Transmitting attachment(s)” window while transmission is underway. Larger files may take several minutes to complete transmission.

The “Attachments(s) successfully transmitted” window displays when the document successfully transmits:


1. Click the “Print response code” button to view and print a record of the transmission for your records:


Note: the response code includes a timestamp that features the date of transmission (for example, 2019-06-17), the transmission time to the millisecond (for example, 10:36:24:680) and the time zone (for example, -04:00).

2. Click the “View transmissions” button to review transmissions and their status related to the T2 return:


An unsuccessful transmission returns an error:


A CRA error code is provided as well as an explanation of the issue.

Address the issue (for example, the file is too large) and reattach and retransmit.

If the issue persists, contact CRA’s Corporation Internet Filing Helpdesk at 1-800-959-2803 for assistance.

The “HyperDocs” feature in ProFile allows users to review previously transmitted documents.
