If you had no income, you can indicate this on your T1 return by entering "0" in the income sections. However, you must report your worldwide income from all sources earned to the CRA on your T1 personal income tax filing to ensure you receive any benefits or credits you are entitled to, such as the Goods and Services Tax/Harmonized Sales Tax (GST/HST) credit or the Canada Child Benefit (CCB).
