GST was introduced on 1 July 2017. It replaced multiple taxes implied by the central and state governments into a single taxation system. Under GST goods and services are being taxed at different tax slabs such as 5%, 12%, 18%, 28%. The registration is mandatory for business whose turnover is more than Rs.20 lakhs (for services) and Rs. 40 lakhs (for goods) yearly. GST Registration is not mandatory in case of e-commerce sellers if total sales are less than Rs.20 lakhs.
