T1-ADJ — T1 Adjustment Request

The preparer must use this form to request an adjustment (i.e. a reassessment) to an individual income tax return. You can get more information about CRA's rules and policies for reassessments in Information Circular IC75-7R3, Reassessment of a Return of Income at canada.ca/en/revenue-agency/services/forms-publications or by calling 1-800-959-8281.

Part B of this form is usually completed by the preparer, however, when the form is completed by the taxpayer, you must enter an "X" in the applicable box at the end of Part B (Authorization).

He must provide a detailed description of each change he requests (he does not have to recalculate the tax amount).

If he is changing a line on which he already claimed an amount and he did not previously provide the supporting documentation, he now has to provide supporting documentation for the entire revised amount.

With ReFILE, you are transmitting an entire T1 return that has been amended to reflect the desired changes. You are not electronically filing a T1-Adjustment form.

However, in Personal Taxprep, we are using the automatic T1-Adjustment feature as part of the ReFILE process so that you can review the lines that have changed in the return and ensure that only the desired changes have been made.

Therefore, the process involved in preparing an amended T1 return will be similar to the process already in place to automatically prepare an adjustment. It is recommended that you use a copy of the data file for the original return when preparing an amended return.

Important information relating to the ReFILE service

To electronically transmit an amended return, you must answer “Yes” in response to the question Do you want to electronically retransmit the amended T1 return (using the ReFILE service) instead of mailing a T1ADJ form? in the “ReFILE” section of Form T1 ADJ, T1 Adjustment Request (Jump Code: T1ADJ).

Once you respond yes to this question, the EFILE status of the return will no longer be “Accepted” and you can then modify the return to reflect the desired changes. Follow the steps on the T1-Adjustment form to electronically transmit an amended T1 return.

The lines that have been changed in the return will be displayed on Form T1-ADJ as will the anticipated change to the refund or balance due. You will need to confirm that the changes indicated are correct in order to transmit the return.

You may want to print Form T1-ADJ for reference purposes and/or to provide to the client, but the client does not need to sign Form T1-ADJ.

Instead, your client will need to authorize the transmission by signing a new copy of Form T183, Information Return for Electronic Filing and Individual’s Income Tax and Benefit Return.

You must then print Form T183, have the client sign it, and retain the original signed copy to be provided upon request.

Once the client has provided authorization, you can transmit the return in the normal manner.

The confirmation number and date accepted will be recorded in both the Form T1-ADJ, T1 Adjustment Request as well as in the Form EFILE INFO, EFILE Information (Jump Code: EFILE INFO).

The EFILE exclusions that apply to transmitting original T1 returns also apply to transmitting amended returns. However, there are also some additional exclusions, including the exclusions that apply when using the Change My Return service via the Represent a Client portal. The EFILE diagnostics will identify amended returns that are not eligible for transmission.
