1- No The Canadian Inland Revenue Department cancelled the consumption tax refund service for foreigners (whether working, studying or traveling) several years ago. Well, I must admit it's deceptive. Compared with Australia and Britain, it's really unbearable. ...

2- Definitely impossible. International students do not enjoy any government financial subsidies, compensation and funding. In fact, when applying for a study visa, there is one thing on the form: "I promise that I will not seek any financial support from the Canadian government for my study and school expenses during my study in Canada."

3- The so-called "tax return" means that you declare your total income in Canada and around the world in the past year to the Inland Revenue Department. According to your report, the tax bureau decided to give you the amount of tax refund. So it's not that you tell the government how much tax you paid, otherwise it will be very troublesome to calculate.

4- No consequences. But I suggest you file tax returns, especially if you want to immigrate in the future. An international student who insists on filing tax returns every year is a "good student" in the eyes of the government.

5- Understand the third point and you will understand. Chinese translation "tax filing" kills people. English translation is to submit tax returns. This translation is completely inconsistent. I don't even know who came up with the word "tax return" ... if you don't have a job at all, report your income directly. It's done.

In addition, I want to tell you that international universities in Canada generally have offices of the International Student Service Department, and they generally provide detailed tax assistance and consultation for international students. If you find it difficult to file tax returns, you can ask them for help.

I hope it helps you, and I wish you all the best! Good luck:-)
