I am an international student and I bought a house. Can I claim the NRST rebate on my house?

Yes you can, but there are some conditions to qualify.

If an International student enrolls in a full-time program from an approved Ontario institution within 2 years from the date of purchase (or acquisition), they can claim the NRST. This rebate is 15% tax on the purchase.

This property should be, or within 60 days of purchase become, your principal residence. This process should be started within the period of four years and 90 days from the date the NRST became payable. Any false information or misrepresentation can cause a penalty, fine and/or imprisonment. There will be an audit on the submission of the application.
