HESS pays hourly for classes taught and guarantees 20 teaching hours a week. Initially all teachers are charged 18% tax by the government. If they are in the country for more than 183 days, then their tax rate drops to 5% and they get the difference back when they file their taxes.
The numbers in this calculator are based on a teacher at the starting pay of NT $620 per hour, before tax with 4.3 weeks in a month. A teacher's starting pay can go up to NT $660 per hour based on previous teaching qualfications - e.g. having an education degree, a TEFL certfiicate, or previous full-time teaching experience.
