Effective 1 April 2025, businesses with an AATO of ₹10 crore or more are required to report e-invoices on the Invoice Registration Portal (IRP) within 30 days from the invoice date. If they miss that window, the IRP blocks IRN generation. For the seller, this means they can't issue a valid tax document. For the buyer, it means ITC gets delayed.
What is the 30-day e-invoice reporting limit?
The 30-day e-invoice reporting limit requires eligible businesses to upload invoices, credit notes and debit notes to the IRP within 30 calendar days of the document date. Once 30 days have passed, the IRP rejects the upload and no IRN is generated. IRIS IRP, one of the authorised invoice registration portals, confirms that the portal displays an error when an invoice is submitted beyond this window.
Who does the 30-day e-invoice rule apply to?
Businesses with an AATO of ₹10 crore or more fall under the IRP 30-day limit. This rule came into effect on April 1, 2025. Businesses below the ₹10 crore threshold do not currently need to generate e-invoices, and the e-invoice 30-day limit does not apply to them.
What happens if an e-invoice is not reported within 30 days?
When an invoice is not uploaded within the 30-day window, the IRP rejects the request and blocks IRN generation. Without an IRN, the document is not a valid e-invoice under GST. The seller then has to re-raise the invoice if the date was entered incorrectly, or accept that the transaction will not have a registered e-invoice. GSTR-1 auto-population fails for that invoice, and manual entry becomes unavoidable, which increases the chance of errors and mismatches in the return.
How does missing the 30-day limit affect sellers?
A missed deadline creates pressure on multiple fronts. The buyer does not receive a valid tax document on time, which can hold up payments. If the original invoice date was entered incorrectly, the seller must correct or cancel and re-raise the document.
GSTR-1 filings take longer because invoices that were failed to be registered on the IRP due to a missed deadline must be entered manually rather than auto-populated from e-invoice data. Buyers who do not receive a valid e-invoice may also dispute the transaction, adding to the follow-up workload.
How does the e-invoice 30-day rule affect buyers and ITC?
ITC is available only when the supplier’s invoice appears in GSTR-2B, and that depends on the supplier having a valid IRN. When the seller misses the 30-day window, the invoice does not auto-populate in GSTR-2B, and the buyer cannot claim ITC on that purchase.
Reconciliation gets harder because the purchase appears in the buyer’s books but not in GSTR-2B. The buyer then has to follow up with the supplier to get the corrected invoice, which delays the ITC claim further and adds to the compliance workload.
How can a business avoid missing the 30-day reporting window?
A few practical measures help businesses stay within the e-invoice 30-day reporting limit.
- Report invoices daily rather than batching them at the end of the month. Daily uploads surface errors early while there is still time to fix them.
- Track pending invoices using the pending invoice report in your accounting software. This shows which documents are still waiting for an IRN.
- Validate master data (GSTIN, HSN codes and recipient details) before raising invoices. Data errors cause IRP rejections that eat into the available time.
- Use a maker-checker flow for invoice approval. A second review before upload catches most entry errors before they reach the IRP.
Conclusion
The 30-day e-invoice reporting limit is manageable when invoice submission is part of a daily routine. Problems mostly arise when businesses batch-upload at month-end and discover errors too late to correct them within the allowed window. TallyPrime helps by tracking pending IRN status, flagging invoices approaching the 30-day cut-off and allowing error correction before upload. This helps the IRP receive clean data from the start.
