You will need to file the previous four years in order that your Tuition & Education Amounts CarryForward. Even if you had no income to pay tax on, you may be eligible for Provincial Benefits and the GST/HST Credit for the years you haven't filed.
Once the previous years are filed, you''ll be able to file your current year return and CRA will apply these Tuition Credits for you automatically.
