GST E-Invoicing in 2026: Who Needs It & How to Comply

E-invoicing is now mandatory for turnover above ₹5 crore. Setup, IRN, QR codes and common errors — explained.

15 April 2026·6 min read

E-invoicing is a compliance requirement — not an optional upgrade. Generate the IRN before you issue the invoice, or your buyer loses their input credit.

Applicability

  • Businesses with aggregate turnover > ₹5 crore in any FY since 2017-18
  • Applicable to B2B invoices, credit notes and debit notes
  • Exempt: SEZ units, insurance, banking, GTA, passenger transport

How to generate IRN

  • Register on the IRP portal (einvoice1.gst.gov.in)
  • Push invoice JSON via API or offline utility
  • IRP returns IRN + QR code — print on invoice
  • IRN auto-populates GSTR-1
