Supporting documentation for online filing

In this part, all elections, designations, agreements, waivers, and special elective returns are referred to as elections.

Elections and supporting documentation

The Income Tax Act provides for various elections to be made. Some are made on authorized Canada Revenue Agency (CRA) forms. Others are made by providing specific information in a letter or note.

Elections and Form T1135, Foreign Income Verification Statement, have to be sent only if they apply to the return you filed. You do not have to send any other supporting document when filing online. Keep all documents used to prepare a return, such as books, records, forms, schedules, and receipts for six years. Be ready to send your documents to the CRA on request.

All elections, including the supporting documentation, must be submitted to the CRA in writing or through the Submit documents online service. For an election to be considered valid, it must be submitted by the due date established in the Income Tax Act.

When submitting this documentation:

  • Clearly state the trust name and the trust account number on all the election forms and letters
  • Clearly indicate in the covering letter that the documentation is submitted to support the trust’s electronically filed return

All other documentation used to prepare the return, excluding elections as indicated, is to be kept and sent to the CRA only if requested.

For more information on other documents available for electronic filing, see Submitting and filing documents online related to T3.

Where to send paper documents

With the exception of Form T1135, all paper documentation to support elections should be sent to the tax centre that serves the area where the legal representative lives. Each election form and letter should include the trust’s name, representative’s name, address, and trust account number. A covering letter should also be included that indicates the documentation is to support the trust’s electronically filed return.

Send your completed Form T1135, Foreign Income Verification Statement, to the tax centre address shown on the form.
