How to ReFILE a T1 return

What is ReFILE?

If you are an EFILE service provider, you can use ReFILE to send T1 adjustments online for tax years 2017, 2018, 2019, and 2020 on behalf of your clients. The ReFILE service lets you change the same lines that individual taxpayers can with the Change my Return service in My Account.

Who can use ReFILE?

Preparers can use the ReFILE service if the following conditions apply:

  • you have ProFile version 2016.4.3 or later (for tax year 2017, 2018, 2019, and 2020 ReFILE)
  • you have level 2 authorization from your client on an Authorize a Rep form
  • the initial return was filed online (EFILE)
  • the initial return was assessed
  • you have acquired a new sign-off of a revised T183 from client

What tax years does ReFILE support?

ReFILE is supported for 2017, 2018, 2019, and 2020 tax years with the latest ProFile version (2016.4.3 or later).

Please see the Frequently Asked Questions section at the bottom of this article for more information.

You can also review the CRA article EFILE for electronic filers for additional information.

Prepare a Return to ReFILE

  1. Open ProFile.
  2. Open a T1 return that has already been filed online, and for which a CRA assessment has been received.

ProFile recommends that preparers save the return as a new file, using the Save As… option from the File drop-down menu in the top toolbar.

  1. Enter the new information that mandates a ReFILE into the return. For example, a client has received an unexpected T4 indicating additional income.

Complete a ReFILE Request Form

You can review our tutorial video on completing a T1 ReFile Request form below:

  1. Open a ReFile Request form:


2. Ensure the client information (SIN, Name) is correct:


3. Enter the current date in the Date of ReFILE field:

4. Select the Yes option in the Is this an amended tax return? field:


Note: failing to select the Yes option will produce an error when attempting to ReFILE.

5. Answer the subsequent questions in the form. Note that in 2019 the question section in the image below was removed and replaced with a Notes section:


Note: these questions are not mandatory and preparers are not required to provide answers. Any notices related to these questions may be ignored.

Verifying an Authorize a Rep form is Present

A valid Authorize a Rep form with level 2 authorization must be on file with CRA for any ReFILE web service transmissions.

If CRA already has the authorization information on file, another filing of the Authorize a Rep form is not required. A preparer needs only to fill out the Authorize a Rep and select 2 authorization in the Level of authorization (1 or 2) section:


Updating the T183 Form

If using module 2016:

  1. Open the T183 Form used for the initial EFILE of the return:


2. Confirm the checkbox under Part C that asks Want to ReFILE like you EFILE? is checked:


A letter R now displays on the T183 form indicating the form was referenced for the ReFILE:


This new designation is permanent and cannot be rescinded from the form.

3. Acquire a new sign-off from the client on the updated T183 form prior to ReFILE attempt.

If using module 2017 and later:

  1. Open the T183 Form used for the initial EFILE of the return:


2. Enter the preparer name (person or firm) and electronic filer number in section C:


A letter R now displays on the T183 form indicating the form was referenced for the ReFILE:


This new designation is permanent and cannot be rescinded from the form.

3. Acquire a new sign-off from the client on the updated T183 form prior to ReFILE attempt.

ReFILE the Return

Select the EFILE/ReFILE this return… option from EFILE top toolbar menu:


The ReFILE process begins; preparers receive a confirmation window if the ReFILE is successful:


Confirming ReFILE

Confirmation on Return's Info page

The ReFILE confirmation number displays automatically on the Info form related to the return; it matches the number displayed in the ReFILE confirmation message.

The confirmation number is displayed in the T1 EFILE/ReFILE confirmation number field:


The ReFILE may be confirmed by examining the history of the return.

  1. Select the Properties option under the File drop-down menu in the top toolbar.

I'm getting an error from the CRA that my EFILE return has not yet been assessed; does this mean I cannot ReFILE?
