E-Invoice Registration

Mandatory for eligible businesses to issue GST-compliant e-invoices.

What is e-Invoice Registration?

e-Invoicing is a system introduced under GST where B2B invoices,B2G , debit/credit notes, and exports must be reported electronically to the Invoice Registration Portal (IRP).

Upon reporting, the IRP:

  • Generates a unique Invoice Reference Number (IRN)
  • Issues a QR Code
  • Validates the invoice as legally compliant

This ensures that invoices are standardized, authenticated, and integrated with GST returns.

Businesses meeting the turnover criteria must register on the IRP and generate e-invoices for every B2B transaction.

Why is it Needed?

e-Invoicing is required to:

  • Prevent invoice fraud
  • Ensure real-time GST reporting
  • Enable auto-population of GSTR-1 & GSTR-3B
  • Allow seamless Input Tax Credit (ITC) to buyers
  • Reduce mismatches and disputes
  • Improve business transparency
  • Ensure compliance under GST rules

For eligible businesses, not generating e-invoices results in invalid invoices.

Such invoices:

  • Cannot be used for ITC
  • Cannot be used for transport
  • Attract penalties

Who Should Apply?

e-Invoice Registration is mandatory for businesses whose aggregate turnover exceeds the notified limit.

Current Turnover Threshold (as of 2025–26):

  • ₹5 crore and above in any financial year since 2017–18 must issue e-invoices.

  • Companies
  • LLPs
  • Partnership firms
