Need an e-invoice summary for 2026? Start with three questions: does your business fall within the mandate, is this document covered, and has the IRP registered it? For the requested Hindi explanation, read the Hindi summary.
Key takeaway: A PDF invoice is not automatically a GST e-invoice. Registration on an Invoice Registration Portal (IRP) produces an Invoice Reference Number (IRN) and signed QR code.
What does e-invoice mean?
You prepare the invoice in your billing system and report its structured data to an authorised IRP. The returned IRN and signed QR code identify the registered document. See the IRP’s explanation of e-invoicing.
The turnover threshold
Notification 10/2023–Central Tax lowered the threshold to aggregate turnover exceeding ₹5 crore, effective 1 August 2023. Check applicable turnover history from FY 2017–18 onward, covered documents and exempt classes; do not decide using only one branch’s sales. Read the notification and the IRP mandate guide.
For an applicable supplier, B2B and export documents are important covered categories. Ordinary B2C invoices are outside this e-invoice reporting mandate. Confirm your specific case before changing your billing process.
Do not confuse ₹5 crore with ₹10 crore
The mandate threshold and reporting deadline are different rules. From 1 April 2025, taxpayers with AATO of ₹10 crore and above must report covered invoices, credit notes and debit notes within 30 days of the document date. Late reporting is blocked for IRN generation. Read the reporting-time advisory.
A business exceeding ₹5 crore but below ₹10 crore can still fall under the mandate. Do not treat the reporting window as permission to issue a required invoice without its IRN.
A daily billing checklist
- Confirm applicability and the buyer’s GSTIN.
- Check document date, number, item details and tax calculation.
- Report through the authorised IRP or a supported integration.
- Save the returned IRN, signed QR code and registered document.
- Track rejected submissions and reconcile records before return filing.
What if an invoice has a mistake?
The IRP permits cancellation within 24 hours of IRN generation, subject to portal conditions. Do not simply edit a saved PDF and assume the registered data changed. Ask your CA about the correct route when cancellation is unavailable. See the IRP cancellation guidance.
Frequently asked questions
Are e-invoice and e-way bill the same?
No. Invoice registration and the movement-of-goods document serve different purposes. Check each requirement separately.
Does IRN generation finish my GST return?
No. Review the relevant return data and complete filing; registration does not replace return filing.
Keep customer and invoice records organised, but verify that your chosen billing workflow actually supports IRP reporting. For more context, read the detailed e-invoicing guide. Summary reviewed on 4 October 2026; recheck official advisories before acting.
