How Does NETFILE Work Exactly?
First, you prepare your tax return with any of the TurboTax Software solutions.
Then, when you complete your return, TurboTax will prompt you to choose to file online with NETFILE. You simply accept the invitation, and follow the on-screen instructions.
The requirements for submitting your tax return to the CRA electronically via the NETFILE service have changed for tax year 2012.
The CRA no longer requires a Netfile Access Code:
The Canada Revenue Agency has eliminated the requirements for the NETFILE Web Access Code (WAC). The WAC was the four-digit personalized code printed on the information sheet of the T1 personal income tax return package. You will still be able to use NETFILE to file your 2012 individual Income tax and benefit returns. The only information you now required, to access NETFILE, is your Date of Birth (DOB) and your Social Insurance Number (SIN).
