e-Invoicing Rule: 30-Day Limit for Businesses with Over ₹10 Cr AATO

Introduction

Effective April 1, 2025, key changes to e-invoice reporting rules will come into force. As part of ongoing efforts to streamline GST compliance, the Indian tax system is introducing a mandatory 30-day deadline for reporting e-invoices on the Invoice Registration Portals (IRP).

Previously applicable only to taxpayers with an Annual Aggregate Turnover (AATO) of ₹100 crore and above, this threshold has now been lowered to ₹10 crore as per the GST advisory issued on November 5, 2024. This article outlines the importance of the new e-invoicing deadline, who it applies to, and the steps businesses must take to ensure timely compliance

30-Day e-Invoice Deadline Now Applies to Businesses With ₹10 Crore Turnover

The Goods and Services Tax Network (GSTN) has tightened the e-invoicing window to improve compliance and efficiency. Beginning 1 April 2025, any business with an Annual Aggregate Turnover (AATO) of ₹10 crore or more must upload its e-invoices, credit notes, and debit notes to the Invoice Registration Portal (IRP) within 30 days of the document date.

How the Rule Has Evolved

Advisory	AATO Threshold	Reporting Window	Effective From
13 Sep 2023	≥ ₹100 crore	30 days	1 Nov 2023
5 Nov 2024	≥ ₹10 crore	30 days	1 Apr 2025

What the New Limit Means

Who’s Affected: All GST-registered businesses whose previous-year AATO is ₹10 crore or above.
Practical Impact: From 1 April 2025, an Invoice Reference Number (IRN) cannot be generated for any invoice, credit note, or debit note older than 30 days.
Transition Period: The five-month lead time gives affected taxpayers scope to upgrade accounting systems, train staff, and tighten invoice-approval cycles.
Unaffected Entities: Businesses with AATO below ₹10 crore may continue to report e-invoices without a statutory time cap.

Next Steps for Taxpayers

Review Turnover: Confirm whether your FY 2023-24 AATO meets or exceeds ₹10 crore.
Update Systems: Configure ERP or billing software to block uploads after 30 days automatically.
Align Workflows: Shorten internal approval times so invoices reach the IRP well before the deadline.
Train Teams: Educate finance, sales, and compliance staff on the revised timelines and penalties for late IRN generation

What Is e-Invoicing Under GST?

e-Invoicing, or electronic invoicing, is a system introduced by the Goods and Services Tax Network (GSTN) where B2B invoices are digitally authenticated before being used for GST compliance. Instead of manually uploading invoices on the GST portal, businesses generate invoices using their internal accounting or ERP systems and submit them to the Invoice Registration Portal (IRP).

The IRP validates the invoice and issues a unique Invoice Reference Number (IRN), along with a QR code. This validated invoice data is then automatically shared with the GST portal and e-way bill system, streamlining return filing and reducing manual effort.

Initially rolled out for large enterprises, the GST Council has progressively extended e-invoicing to medium and small businesses, making it a standard compliance requirement across various turnover thresholds

Who Must Generate e-Invoices? — Applicability Based on Turnover

The requirement to generate e-invoices is based on a business’s Annual Aggregate Turnover (AATO). Below is a phased rollout of e-invoicing applicability:

Phase	Turnover Threshold (AATO)	Applicable From
I	₹500 crore and above	1st October 2020
II	₹100 crore and above	1st January 2021
III	₹50 crore and above	1st April 2021
IV	₹20 crore and above	1st April 2022
V	₹10 crore and above	1st October 2022
VI	₹5 crore and above	1st August 2023

As per the latest compliance update, from 1st April 2025, all businesses with an AATO of ₹10 crore or more must not only generate e-invoices but also ensure that each invoice is reported to the IRP within 30 days of its issuance

Benefits of the 30-Day e-Invoice Reporting Limit for SMEs

The extension of the 30-day e-invoice reporting deadline to businesses with an annual turnover of ₹10 crore brings multiple advantages, especially for small and medium enterprises (SMEs):

Lower Compliance Pressure: SMEs now have a broader window to prepare and report invoices, reducing the likelihood of errors and avoiding penalties for late submission.
Better Cash Flow Planning: The added flexibility helps businesses manage cash flows more efficiently by aligning invoice processing with payment cycles.
Boost to e-Invoicing Adoption: With a manageable timeline, more SMEs may feel encouraged to adopt e-invoicing, promoting transparency and streamlining tax compliance across the ecosystem

Risks of Missing the 30-Day Reporting Window

Failing to report e-invoices within the 30-day timeframe can lead to several operational and financial setbacks:

Invoice Rejection by IRP: Invoices reported beyond the 30-day limit will be automatically rejected by the IRP, making it impossible to generate an IRN.
Need to Re-Issue Invoices: Businesses may be forced to cancel and re-issue invoices, leading to confusion, extra work, and the risk of duplication.
Disruption in ITC Claims and Cash Flow: Delays in reporting can interrupt the timely flow of Input Tax Credit (ITC), affecting vendor relationships and liquidity.
Risk of Penalties and Audits: Consistent non-compliance could trigger GST audits, legal notices, and financial penalties
