If your business has AATO of ₹10 crore or more and a covered e-invoice document is older than 30 days, the IRP reporting restriction introduced from 1 April 2025 can block IRN generation for that document. Overall e-invoicing applicability generally starts at ₹5 crore AATO for notified taxpayers, subject to exemptions. Do not backdate or create a substitute invoice without reviewing the original invoice date, document type and customer impact.
What this means for the business owner
If your business has AATO of ₹10 crore or more and a covered e-invoice document is older than 30 days, the IRP reporting restriction introduced from 1 April 2025 can block IRN generation for that document. Overall e-invoicing applicability generally starts at ₹5 crore AATO for notified taxpayers, subject to exemptions. Do not backdate or create a substitute invoice without reviewing the original invoice date, document type and customer impact.
The return/application history and underlying source records should tell one consistent story before any correction, payment or clarification is submitted.
Who should use this guide
This guide is for taxpayers facing the exact fact pattern in the title. It is especially useful when the portal and your books/documents do not agree, when another person handled the original filing, or when a current application/return deadline is approaching.
Why this problem usually happens
Missed windows usually come from offline ERP queues, failed IRP integration, old manual invoices or delayed identification of applicability.
What should be checked immediately
Do not start with a correction entry. First collect the minimum evidence needed to prove what actually happened.
| AATO | E-invoice issue |
|---|---|
| ₹5 crore to below ₹10 crore | Mandate may apply; 30-day IRP restriction described here is not the ₹10 crore+ rule |
| ₹10 crore or more | 30-day reporting restriction applies under current IRP guidance |
| Exempt entity/supply | Separate exemption review required |
What to do now
Check PAN-level AATO history, exemption status, GSTIN, invoice/document type and invoice date. Capture IRP error, reconcile GSTR-1 and customer status, then obtain a transaction-specific correction view rather than fabricating an IRN.
Before submission, the client should receive a concise summary of the problem, the proposed tax/ITC/registration treatment, payment impact and any unresolved item. After submission, keep the ARN/order/acknowledgement and filed copy.
The 2026 legal and portal position
Official IRP guidance states the 30-day reporting restriction applies to taxpayers with AATO ₹10 crore and above from 1 April 2025. E-invoicing mandate applicability was reduced to ₹5 crore AATO from 1 August 2023 under Notification 10/2023, subject to exclusions.
GST Portal workflows, notifications and due-date extensions can change. The official sources below were checked for this article on 19 August 2026; recheck them immediately before filing if the matter is time-sensitive.
A realistic hypothetical
A ₹15 crore-AATO company discovers a B2B invoice 45 days after invoice date. IRP rejects reporting under the 30-day restriction. The business must review the customer invoice and GST reporting consequences; it should not simply issue a fake current-date invoice for the same historic supply.
What happens if the problem is ignored
Missing IRN can affect invoice validity and buyer ITC/commercial acceptance, and create GSTR-1/e-invoice reconciliation gaps.
What TargoLegal checks before filing or responding
TargoLegal checks AATO, exemption, invoice type/date, IRP error and return/customer impact before recommending next steps.
Before filing
Documents received, missing items, reconciliation difference, legal/portal route, payment impact and client approval.
After filing
Filed copy, ARN/acknowledgement, payment proof and a short open-items list for the next period.
What to send for a first review
Missed IRN window? Send turnover/AATO and invoice date.
Related questions
What should I send first?
Send the GSTIN/ARN, the exact period or application stage, and the document that shows the problem. For this topic, the most useful starting point is: PAN-level AATO history, GSTIN/e-invoice applicability, Invoice date/type.
Can I fix this by making an adjustment in the next return?
Not automatically. A later adjustment is appropriate only when the GST law and current portal workflow allow it and the original error has been reconciled.
Should I rely only on what the GST Portal auto-populates?
No. Portal data is essential evidence, but the taxpayer remains responsible for reconciling it with books, invoices and the applicable legal conditions.
What should I keep after the correction or filing?
Keep the filed return/form, ARN or acknowledgement, payment evidence, reconciliation working and any supplier/customer correspondence that explains the change.
When should professional review be considered?
Use professional review where the issue affects material tax or ITC, several periods, a registration notice, refund, e-invoicing, cancellation/revocation or a customer’s credit.
