There is no need to register for NETFILE, but you should need to register for a CRA My Account if you haven’t already. This will make it easier when submitting your tax return since you can take advantage of features such as “Auto-fill my return”. This does not apply to first-time filers since the CRA requires you to file at least one tax return before you can register for a CRA My Account. If you haven’t registered for an account, you can still use NETFILE to submit your tax return electronically.
