  • direct-deposit information (nor can direct deposit be requested)

Web access code

If you cannot access your WAC online or want to change it, call the Business Enquiries line at 1-800-959-5525.

Supporting documentation for online filing

What is required

Note

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

Only elections and Form T1135, Foreign Income Verification Statement, have to be sent 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 Canada Revenue Agency (CRA) on request.

Some elections are made on CRA forms, while others are made by providing specific information in a letter or note. All elections, including supporting documentation for those elections, must be sent to the CRA in writing, unless otherwise indicated. For an election to be considered valid, the CRA must receive the election no later than the due date given in the Income Tax Act.

Where to send the 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 in support of the trust’s electronically filed return. 

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

Filing a T3 return on paper

Send the T3 return by mail to the apporpriate tax centre. For more information, go to Where to file a T3 return.
