Why am I not eligible to file my tax return using NETFILE?
If you still feel that you are eligible, please go through the My Info part of the review again and make sure all the questions are answered, and that they are answered correctly. Ex: On the Contact Info page, make sure you have answered NO to the question “Is your mailing address outside Canada?”.
Also, if you didn’t do so before, go through the Review before using NETFILE.
