What this covers

Common questions

What is the current e-invoicing turnover threshold?
E-invoicing is mandatory for businesses with aggregate turnover above ₹5 crore in any financial year from 2017-18 onwards. The threshold has been progressively reduced from ₹500 crore down to ₹5 crore.
Which documents require IRN?
Tax invoices (B2B, exports, SEZ supplies), credit notes and debit notes issued under section 34 of the CGST Act. B2C invoices do NOT require IRN but must carry a QR code if turnover exceeds ₹500 crore.
Who is exempt from e-invoicing?
SEZ units (but not SEZ developers), banks, insurance companies, financial institutions, NBFCs, GTAs, passenger transport, multiplex/cinema admissions, and government departments are notified as exempt regardless of turnover.
Is there a time limit to generate an e-invoice (IRN)?
Yes. Taxpayers with aggregate turnover of ₹10 crore or more must report invoices to the Invoice Registration Portal within 30 days of the invoice date (effective 1 April 2025). Older invoices are rejected by the portal.
What happens if I don't generate an e-invoice when required?
An invoice without a valid IRN is not a legal invoice, so the buyer cannot claim ITC. A penalty of ₹10,000 per invoice (or 100% of the tax due) can apply, plus ₹25,000 per invoice for an incorrect e-invoice.
How do I cancel an e-invoice?
An IRN can be cancelled on the portal within 24 hours of generation, and only in full (partial cancellation is not allowed). After 24 hours you must issue a credit note instead.
