Time Limit for Reporting e-Invoices on IRP Portal | GST E-Invoicing Guidelines 2025

One of the most important elements of the GST system is the time limit for reporting e-invoices on IRP Portal, which requires businesses to not only correctly generate invoices but also report the invoices to the IRP within the specified timelines for compliance purposes. Read this article more to learn about what it is and how should your business operate under its guidelines.

Starting June 1, 2025, the IRP system will no longer count invoice numbers as case sensitive for IRN generation and will convert all invoice numbers to uppercase automatically, to promote consistency and to avoid duplication. Also, as communicated in the advisory on the GSTN portal on November 5, 2024, for taxpayers whose AATO is over ₹10 crore, the 30-day deadline for reporting e-invoices on the IRP portals will be applicable starting April 1, 2025, to give them enough time to comply with it.

What is the E-Invoice Reporting Time Limit?

The reporting timeframe for e-invoices on the IRP is for invoices, credit notes, and debit notes, 30 days after the invoice date.

Previously, the government proposed a reduced timeframe of seven days, but this was eventually modified and postponed so that businesses would have adequate time to adjust. The 30-day timeframe now creates a balance between compliance and operational flexibility.

For example, if the invoice is dated 2nd November 2023, then the latest reporting date to the IRP would be 1st December 2023. The purpose of this time limit is to report the tax compliance information supplied by taxpayers accurately in real-time, to limit manipulation, and to maintain smooth supply chain operations.

Applicability of the Time Limit

The timeframe is not a generic timeframe for all taxpayers, but rather is linked to the thresholds of AATO. The table below outlines applicability:

Effective Date	Taxpayer Category (AATO)	Reporting Time Limit
From 1st Nov 2023	₹100 crore and above	30 days
From 1st Apr 2025	₹10 crore and above	30 days
Ongoing	Less than ₹10 crore	Not Applicable

This staged rollout gives mid-sized businesses time to get compliant, but large companies must comply with the board 30 days' requirement.

Legal Framework and Notifications

It's also important to note that the GST ACT itself is not a statutory requirement for when an invoice must be submitted. It's an obligation derived from GST Network (GSTN) notifications and the e-invoicing design of the IRP system. The GST ACT continues to deal with the time period under which a supply is made and when an invoice must be issued, but the IRP validation rules effectively impose on the businesses with a legal requirement to report e-invoices within 30 days. This means that a business cannot be legally compliant, purely because the IRP will not accept any "old" invoices, whether compliant or not, if they are submitted after the 30 period.

Consequences of Non-Compliance

The implications of not reporting invoices on time are much more severe.

1. The invoice is rejected by the IRP: If an invoice is older than 30 days, it cannot be registered, forcing businesses to reissue documentation.

2. Delay in compliance filings: Since e-invoices auto-populate into GSTR-1 returns, a delay in the reporting cycle must occur.

3. The Input Tax Credit (ITC) is disrupted: Downstream buyers would have an ITC mismatch, which could cause them to conflict with their customers.

4. Penalties under the GST law:

Incorrect invoicing = ₹25,000.00 per invoice (missing the IRN/QR code)
Failure to generate an e-invoice = 100% of the tax due, or ₹10,000.00 per invoice, whichever is higher.

Practical Impact on Businesses

For such businesses with turnover above the ₹10 crore (θ) threshold, complying with the e-invoice extended deadlines has now become a compliance duty. Larger businesses with turnover greater than ₹10 crore have also taken up IRP integrations with automobile ERPs to get their invoices reported automatically now.

Small and medium enterprises that are still working on the deadline of April 2025 will need to consider:

Upgrading your ERP or accounting systems will allow you to connect to the IRPs in real-time.
Training staff to look out for compliance deadlines.
Building some reconciliation procedures to position yourself away from ITC disputes.

Failure to do so means not only that you will get penalties, but you will also incur your business a loss of credibility with your customers or vendors that could shake their confidence in your business.

Conclusion

The government is gradually broadening e-invoicing to a larger taxpayer base. Should e-invoicing uptake continue to improve, shorter reporting windows could return in the future. Businesses should therefore future proof their systems by investing in automation and compliance ready infrastructure. By aligning operational processes with regulatory requirements, organizations can mitigate risk, keep tax credits flowing without interruption, and improve their competitive position.
