If an eligible loan is refinanced, it will lose its
eligibility for the tax credit, unless the refinancing is
done under the above-mentioned legislation.
There are both federal and provincial non-refundable tax
credits for student loan interest. The tax credit is
calculated by multiplying the lowest
federal/provincial/territorial tax rate by the amount of the
loan interest, except in Québec, where the rate of 20% is
used.
Tax tip: If you do not
need to claim the student loan interest because your taxes
are already zero, save it to claim in a future year.
