How to complete and file a Part XVIII Information Return – International Exchange of Information on Financial Accounts slips and summary

Under Part XVIII of the Income Tax Act, Canadian financial institutions are required to:

  • apply due diligence procedures to identify U.S. reportable accounts and accounts held by non–participating financial institutions; and
  • annually report to the Canada Revenue Agency (CRA) the information required on a Part XVIII Information Return.

The following information relates to the reporting aspect — how to complete and file the new return. These instructions are to be used in conjunction with the Guidance on Enhanced Financial Accounts Information Reporting – Part XVIII of the Income Tax Act, XML specifications and schema. The guidance document provides details on due diligence and reporting obligations. It is also designed to help financial institutions prepare for the release of that information return. 

Due date

The Part XVIII Information Return (slips and summary) must be filed before May 2nd of the following calendar year to which the information return applies.

When the due date falls on a Saturday, a Sunday, or a public holiday recognized by the CRA, we consider your return to be on time if we receive it on the next business day. Your return is considered on time if we receive it or if it is postmarked on or before the next business day.

For example, returns for the 2020 tax year are due before May 2, 2021. Since May 1, 2021 is a Saturday, the due date is May 3, 2021.

What's new

As of May 2021, the procedures to target records for an amendment, cancel or fix return have been updated. When filing an amendment, cancel or fix return it is critical that the correct reporting financial institution record be targeted to avoid errors. As such, financial institutions are required to keep track of which slips belong to which reporting financial institution record. For more information, go to After you file a Part XVIII or Part XIX Information Return.

Also effective May 2021, you can no longer file an amended return without a slip. You can now cancel the reporting financial institution record, but only if all of the associated slips are cancelled.
