Why is TELEFILE only available to certain people?
TELEFILE is designed for taxpayers with the most common types of income tax information such as employment income, pension income, interest income, registered pension plan contributions, and charitable donations. More complex tax information, such as self-employment income, capital gains and rental income are not accepted by the system, since they would take more telephone time and could require documentation before we can process them. Requests for documentation would slow our processing times.
