E-Invoicing Under GST in 2026: Do You Need It Now?

GST e-invoicing — where invoices are validated on a government portal and get an IRN (Invoice Reference Number) — started with only the largest businesses. But the turnover threshold has steadily come down, pulling in more and more mid-sized businesses. Do you need it now?

How e-invoicing works

Instead of just issuing an invoice, you upload its details to the Invoice Registration Portal, which returns a unique IRN and a signed QR code. Only then is the invoice valid for GST purposes. It flows automatically into your returns and your customer's 2B.

Who needs it

E-invoicing applies to B2B invoices once your aggregate turnover crosses the notified threshold in any year. Because that threshold has been reduced over time, businesses that were exempt before may now be covered — so check your turnover against the current limit.

Getting it right

• Confirm whether your turnover crosses the current threshold.
• Set up e-invoicing in your billing software.
• Generate the IRN for every applicable B2B invoice.

E-invoicing actually reduces work once set up — fewer mismatches, auto-populated returns. The key is knowing if you've crossed the threshold, since applying it late (or ignoring it) causes compliance problems. Confirm the current limit for your business.
