TaxCycle T2 is certified by CRA for electronically filing the T1134 Information Return Relating To Controlled and Not-Controlled Foreign Affiliates. Here's what you need to know to get set up and transmitting T1134 forms.

EFILE number and password

To electronically file T1134s with the Canada Revenue Agency (CRA), you must have an EFILE number and password issued by the Canada Revenue Agency (CRA):

  • To register for EFILE and receive these credentials, go to the CRA electronic filers page
  • If you already have an EFILE number, you must complete a yearly renewal to receive a new password for the latest T1 tax season. Always use the latest password given to you.

The registration or renewal process includes a suitability screening. This process may take up to 30 days. To allow enough time for the review of your application before the filing season starts, we encourage you to renew your application as soon as possible.

Enter the CRA EFILE number and password in TaxCycle options:

  1. If you have a file open, go to the File menu, then click Options. To open Options from the Start screen, click Options in the blue bar on the left side. (You can also access these EFILE options any time by clicking on the wrench icon in the Transmit sidebar.)
  2. On the left side of the screen, expand Transmission and then click on EFILE Accounts.
  3. Enter your CRA EFILE Number and EFILE Password.

Answer "Yes" to the T1134 question

Review messages and transmission function for the T1134 form are triggered based on a question in the Filing section on the Info worksheet. Answer Yes to this question.


2018-t1134-outstanding-error-efile Complete the T1134 and T1134Sup

Once you answer Yes to the question on the Info worksheet, the T2 T1134 box appears in the Transmit sidebar. It will show any outstanding errors preventing filing of the T1134:

  1. Complete the T1134.
  2. Complete one T1134Sup for each foreign affiliate and/or controlled foreign affiliate.
  3. To file amended, cancelled, or additional slips or summary, select the correct check box at the top of the forms. For more details, see the section on How to file amended T1134 and T1134Sup, below.
  4. Click Transmit in the sidebar, or press F12.
  5. Click once on the T2 T1134 box to expand it and see a list of all outstanding errors preventing filing of the T1134.
  6. Click a blue link to jump to a field and address an issue.

T1134 certification date

A review message will prompt you to enter a certification date on the T1134. The T1134 uses the same date set for the T2 return. This information flows from the Filing section on the Info worksheet.

Confirm signature of the T1134

The CRA requires that the taxpayer sign a paper copy of the T1134 before the preparer can electronically file it on his/her behalf. It is also important that you keep this signed form in your files should the CRA ask for it. They regularly check with preparers. 

By default, TaxCycle requires you confirm the taxpayer has signed the form before you can transmit. Do this from the transmit sidebar:

  1. 2018-t1134-efile-confirm-signatureClick T1134 link to open the form.
  2. Click Print the T1134 link to print the form on whatever printer is configured for single-form printing. This opens the Print/Generate forms dialog box, where you can change the printer/output settings. From this dialog box, click the Print or Generate button to print/PDF the form. You can also send this document for electronic signature. (Read the Print/PDF a Form help topic to learn more about the options available from this box.) 
  3. TaxCycle records the date and the name of the person who printed the form. Click the link to print it again if need be.
  4. Once you have a signed T1134 on file, click the Confirm signature link. TaxCycle records the signing date and the name of the person who confirmed the signature.


Transmit a return

  1. Once you confirm the signature, the return is Ready to transmit
  2. Click the Transmit Now! link to begin the transmission.

You can also transmit other returns and requests (like T2 CIF or T1135) at the same time by using Transmit multiple. Learn how in the Transmit Multiple help topic.

Successful transmission results

2018-t1134-successful-transmissionIf a T1134 transmission is successful, you will see:

  1. The words Transmission successful in green text and green happy face. This is the same symbol that appears in the Client Manager for returns that have been successfully filed, and it also appears (white on blue) in the blue bar at the bottom of the window of any open tax return, so you can quickly see the current filing status.
  2. The box also shows the Confirmation number and Transmission number for future reference. 
  3. Any messages returned from the CRA appear in this box. They begin with the number. Click the more link to see the full message.
  4. Click the Print the T1134 Receipt link to give a copy of this information to your client.
  5. Click the T1134 Electronic Transmission Results link to view the worksheet which contains a full list of the results from all transmission attempts.
  6. In the rare case you need to re-transmit the form, click Dismiss all CRA messages and start again.

Rejected transmission with errors

If a T1134 transmission is rejected by the CRA due to errors, you will see:

  1. Transmission rejected and a red sad face. This is the same symbol that appears in the Client Manager for transmission that have failed, and it also appears (white on blue) in the blue bar at the bottom of the window of any open tax return, so you can quickly see the current status.
  2. Any error messages received from the CRA also appear in this box, starting with the error number. This number may be useful if you need to contact the CRA regarding an error.
  3. The longer error description usually contains information on what went wrong with the transmission, so you can work to correct it.
  4. Click the T1134 Electronic Transmission Results link to view the worksheet which contains a full list of the results from all transmission attempts.
  5. When you have resolved the issue, click Dismiss results and start again to re-transmit. This rechecks the return for outstanding errors before returning to the transmission step.


After successful transmission, the T1134 shows a watermark—on screen and when printed—to remind you and your client that the statement has already been submitted to the CRA and the form should not be sent by mail again.


T1134 results worksheet

The T1134 Results worksheet lists the results of any attempts to electronically file a T1134.  Regardless of a successful or failed transmission, TaxCycle records the time and the result of the transmission, so you always have a complete record of transmission attempts and returned messages, even if you have to re-transmit the return.

How to file amended T1134 and T1134Sup

  1. For any amended, cancelled or additional slips, check the appropriate box at the top of the affected T1134Sup:
  2. Check the first box at the top of the T1134 summary. This marks the form as amended and puts a watermark on the form.
  3. If the T1134 summary is amended in addition to the slips, check the second box.
  4. The field with the summary filing code will automatically change based on this selection.
  5. In the Transmit sidebar, click the link to Dismiss results and start again, then follow the same steps as above to the file return.

Transmission history

No matter what type of transmission you make (EFILE, ReFILE, PAD, T1135, etc.), each transmission attempt is recorded in the file history:

  1. Go to the File menu, then click on Info
  2. Click on History
  3. Find the record of the transmission in the list.
  4. Click the first save button (the one with the lightning bolt) to save a copy of the XML file that was transmitted to the CRA.
  5. Click the second save button (the one with the green arrow) to save a copy of the response sent back from the CRA.
  6. TaxCycle also updates the workflow information for the taxpayer. (See the Workflow Groups and Tasks help topic.)
