Like any Canadian, students including international ones must complete their annual tax return. Although they may not have earned income to report, they may be eligible for certain tax refunds or credits. INTERSTUDCanada will fill in your tax return for you in order to facilitate this task.
An Individual Tax Number (ITN) is allocated to international students who have never worked and who declare income annually. If you need it, let INTERSTUDCanada know who will make the application for you.
As for the Social Insurance Number (SIN), It is mandatory to have one before taking a job in Canada. Contact INTERSTUDCanada once an employer makes you an offer of employment. INTERSTUDCanada will fill out the form for your SIN application and either will take you to the office for submission or will send it by mail on your behalf.
