What is the HSN code for the GST registration portal?

The official government GST portal is a platform of the Government and does not raise GST invoices. But private service providers who help with GST registration and filing use service codes. Such services often fall under information technology and support service headings, such as 99831 or similar IT related service codes.

How GST registration and filing portals are classified under HSN?

  • Online GST filing platform that charges service fees: service code under IT or online information services
  • Professional firm doing registration and monthly filing: professional, tax, or legal service codes
  • Back office that only uploads data: business support services

GST implications on portal services

Service providers that assist with GST registration and filing must:

  • Charge GST on their service fees at rates like 18 percent
  • Use proper HSN or SAC code on invoice
  • Allow clients to claim ITC if conditions are met

The government GST portal itself does not charge GST on tax paid, since it is tax, not service fee.
