The most common post-secondary non-refundable tax credits that apply to students are interest paid on student loans, the tuition, education and textbook amounts, the public transit amount, and the Canada employment amount.
Interest on Student Loans
To be eligible for the credit, interest must, in fact, have been paid. The interest must be on a loan made under the Canada Student Loans Act, the Canada Student Financial Assistance Act or a law of the province or territory, which governs the granting of financial assistance to students at the post-secondary level. Personal or family loans will not qualify. Credits that are not needed to offset income taxes are available for carry forward for up to five years. You can only claim interest you have not previously claimed and you cannot claim interest that relates to a judgment obtained after you failed to pay back a student loan
