My Sister Sophie has recently started her teaching career on Udemy as a Canadian Tutor for 6 months now. She teaches accounting to her students. At first, she finds it difficult to calculate the prices of her tailored courses, which include HST taxes only from Canadian Students. But when I suggested to her this tax calculator Ontario, she found it easy to calculate Federal Tax and Provincial taxes as well, without logging in or any ads. The best part is that we can even “Download PDF”.
