What Is the 30-Day IRN Reporting Window for E-Invoices?
The 30-day IRN reporting window is a deadline for uploading e-invoices to the Invoice Registration Portal (IRP). Under a GSTN advisory issued in November 2024 and effective 1 April 2025, a business with aggregate turnover of ₹10 crore or more must report each invoice, credit note, and debit note within 30 days of its document date. Miss it and the IRP refuses to generate the IRN, which leaves the invoice without a valid e-invoice and puts the buyer input tax credit at risk.

As long as you eventually upload an e-invoice, the date you report it does not matter.
For businesses with aggregate turnover of ₹10 crore or more, the Invoice Registration Portal rejects any invoice reported more than 30 days after its document date, effective 1 April 2025 per the GSTN advisory.
What is the 30-day IRN reporting window?
Short answer
It is a hard deadline to upload an e-invoice to the IRP: the invoice must be reported within 30 days of its document date, effective 1 April 2025 per the GSTN advisory.
E-invoicing is not finished when you print the bill. You report its details to the Invoice Registration Portal, which returns the IRN and signed QR code under Rule 48(4). The 30-day rule puts a clock on that step: the portal counts 30 days from the date on the document and will not accept a late upload.
Which businesses does the 30-day clock apply to?
Short answer
Businesses with aggregate turnover of ₹10 crore or more in any financial year from 2017-18 onward, per the GSTN advisory effective 1 April 2025.
- The window applies to invoices, credit notes, and debit notes alike, each measured from its own document date.
- Below ₹10 crore turnover, the 30-day limit currently does not bite, though e-invoicing itself may still apply from ₹5 crore.
- The turnover slab for this rule has been tightened over time, so confirm the current GSTN advisory before relying on a higher cut-off.
What happens if you miss the 30-day window?
Short answer
The IRP refuses the upload, so no IRN is generated, and an e-invoice without an IRN is not a valid document for the buyer to claim credit under Section 16.
- A rejected invoice cannot be salvaged after the deadline, so the discipline is to report close to the invoice date, not at month-end.
- The buyer's input tax credit rides on a valid IRN, so a late, IRN-less invoice can cost your customer the credit.
- Late reporting can also leave a gap between your books and your GST returns that has to be reconciled.
How is this different from the ₹5 crore e-invoicing threshold?
Short answer
The ₹5 crore threshold decides whether you do e-invoicing at all; the 30-day window decides how quickly you must report once you do.
- Crossing ₹5 crore turnover brings you into e-invoicing and the IRN requirement.
- Crossing ₹10 crore turnover adds the 30-day reporting deadline on top.
- A business can be in e-invoicing without yet being under the 30-day clock, which is why the two limits are easy to confuse.
