You may be eligible for a refund. This is only available by filing. You may be eligible for benefits or credits payments. Filing a tax return will ensure that the CRA is using the most accurate information to calculate benefit and credit payments . You could be eligible for certain benefit and credit payments, such as the Goods and Services Tax/Harmonized Sales Tax (GST/HST) credit, the Canada child benefit (CCB) or the Guaranteed Income Supplement (GIS). The longer you wait to file, the more likely it is that payments will be interrupted.
