Open February to September, this service is one of the electronic filing options available to Canadians, to transmit their tax returns to the Canada Revenue Agency (CRA). Using software approved by the CRA, filers prepare their tax returns, and then upload them on the CRA's website using a code provided to them in their annual tax package.

It is important to note that filers can not make changes to their personal information such as name, address, date of birth, or direct deposit information, when using Netfile. To make changes to your personal information using your return, you must file your return by the traditional paper method. Alternatively you can change your personal information by contacting the CRA directly.
