Do tutors need to charge GST?
The GST exemption for education covers schools and institutions that teach towards a qualification recognised by law. Private tuition and coaching classes aren't covered by it, so they're taxable like other services.
In practice, most individual tutors are below the registration threshold - ₹20 lakh of turnover a year, or ₹10 lakh in some special-category states - and invoice without GST, as in this example. Once registered, coaching services are generally taxed at 18%.
