do International students who work and study in Canada need to file T1 tax returns in Canada?
If you are an international student studying in Canada and have Canadian income, you are required to file a tax return. You must determine your residency status to know whether you need to file it as a Canadian resident or non-resident. You can read Taxes for International students studying in Canada on the CRA website for more information. You can contact student service in your university or college for more information or call CRA directly for guidance.
You may be eligible for some benefits and credits by filing a tax return, e.g. GST credits, tuition carryon-forward credits, and other provincial credits or tuition rebates.
