The GST portal was developed to ensure a smooth transition to GST. Along with tracking all transactions, it also offers services like GST registration, filing returns, maintaining all tax details, and more. Instead of dropping emails to the helpdesk, taxpayers can also use this portal to lodge complaints. However, a lot of users have complained about the ‘emSigner error’.
