EFILE for Electronic Filers

Important notice

Auto-fill my return
Auto-fill my return is a new secure Canada Revenue Agency service. It allows authorized representatives to electronically request and receive certain tax information to fill in parts of their client’s income tax and benefit return.

EFILE is an automated service that permits those who prepare and file taxes on behalf of others to electronically file the current and first prior year income tax and benefit return to the CRA directly from the software used to prepare the tax return.

To become a registered electronic filer you must first register or, if you already have a tax preparer number, you must renew.

EFILE web service allows you to transmit your client's returns directly from your tax preparation software. You get an acknowledgement of the individual return instantly. Your software has the capability to simulate the batch filing process by transmitting multiple returns at once, and providing an instant acknowledgement of each return that you have transmitted.

If your business provides tax-discounting services, see our Web page with information for discounters.
