From registration to return filing to cancellation of registration, all these tasks can be performed at this portal. To put it in colloquial terms, it is from “womb to tomb” for  all  registrations. When GST was introduced in July 2017, there were around 64 lakhs existing taxpayers registered under various indirect tax laws. Along with them many more were expected to register under this act. Therefore a very robust, quick, and resilient portal was needed which could handle such a large number of taxpayers and other allied services.

It performs all the functions of tax management like tax determination, tax collection, refund, management of taxpayers, distribution of revenue among States and Centre etc. By March 2018 there were more than 1.03 crore registered persons. Therefore this portal was upgraded to handle 3 lakh returns simultaneously. Some of its functionalities are;

  • Voluntary payment of tax
  • Appeal to the authorities
