30-day e-invoice reporting rule: What businesses with ₹10 crore turnover must know: Businesses covered under the Goods and Services Tax (GST) e-invoicing framework need to pay close attention not only to whether e-invoicing applies to them, but also to when they must report invoice details.
For businesses with an aggregate annual turnover (AATO) of ₹10 crore or more, applicable invoices must be reported to the Invoice Registration Portal (IRP) within 30 days from the invoice date.
This requirement makes timely billing, accurate data entry and suitable accounting systems important parts of GST compliance. Understanding the current e-invoice applicability rules and the 30-day reporting requirement can help businesses organise their invoicing processes and reduce the possibility of delays.
What is e-invoice applicability under the current GST rules?
E-invoicing under GST is a system through which businesses submit specified invoice details to the IRP for authentication. The business continues to prepare the invoice through its accounting or Enterprise Resource Planning (ERP) software. The IRP validates the submitted information and, when the invoice passes validation, generates an Invoice Reference Number (IRN) and a digitally signed QR code.
Right now, whether you need to use e-invoicing depends on your total annual turnover. If your combined turnover across all GSTINs under one PAN is more than ₹5 crore, you must follow the e-invoicing rules for the relevant transactions.
The e-invoice requirement generally covers B2B supplies and exports for businesses that fall within the prescribed threshold. Certain entities and transactions are excluded from the requirement. Businesses therefore need to assess their turnover, GST registration details and transaction types before determining their specific compliance requirements.
Who must follow the 30-day e-invoice reporting requirement?
The 30-day reporting requirement applies to taxpayers whose aggregate annual turnover is ₹10 crore or more. From 1 April 2025, such businesses have been required to report applicable invoices to the IRP within 30 days of the invoice date.
This rule is particularly relevant because meeting the broader e-invoicing threshold does not automatically mean that every business follows the same reporting timeline. Businesses with turnover at or above ₹10 crore have the additional 30-day reporting requirement.
For example, if an applicable invoice is dated 10 August, the business needs to ensure that the invoice is reported within the prescribed 30-day period. This means invoicing teams cannot treat IRP reporting as an activity that can be postponed indefinitely after an invoice is issued.
The rule also highlights why businesses should regularly monitor turnover and keep their accounting systems aligned with GST requirements. A business in the applicable category should ensure its invoicing workflow allows enough time to validate and correct errors.
What happens if an invoice is reported after the deadline?
For businesses covered by the 30-day requirement, late reporting can create a compliance issue. This makes timely reporting an important operational requirement. Businesses should not wait until the end of the reporting period to identify whether invoices have been successfully processed. Instead, invoice generation, validation and IRP reporting can be incorporated into the regular billing workflow.
Accuracy is equally important. Incorrect GSTINs, duplicate invoice numbers, missing HSN or SAC codes, incorrect tax information and errors in the place of supply can result in invoice validation issues.
A well-managed process can therefore help businesses identify errors closer to the point of invoice creation, giving the finance or accounts team an opportunity to address them within the applicable timeline.
How can businesses prepare their billing and ERP processes?
Businesses can take several practical steps to make their invoicing systems better aligned with the 30-day reporting requirement.
Review e-invoice applicability
Start by checking whether the business falls within the current e-invoicing threshold and whether its transactions are covered. Since the threshold is based on aggregate annual turnover across GSTINs under the same PAN, businesses should consider their overall turnover rather than looking at individual locations in isolation.
Check ERP compatibility
The billing or ERP system should support the required e-invoicing workflow. Invoice information needs to be submitted to the IRP in the prescribed format. Businesses can review their existing software and confirm that the required integration or submission mechanism is available.
Keep master data updated
GSTINs, HSN or SAC codes, tax rates, customer information and other invoice details should be checked regularly. Maintaining accurate master data can reduce avoidable validation errors during invoice submission.
Establish an internal reporting process
Businesses can define responsibility for invoice generation, verification and IRP reporting. A simple internal process can help ensure that applicable invoices are monitored from the date of issue until successful IRN generation.
Monitor rejected invoices
An invoice that does not pass validation should be reviewed promptly. Finance and accounts teams can check the reason for rejection, correct the relevant information and follow the applicable process for resubmission.
Can a business loan support GST-compliant technology upgrades?
For some businesses, improving billing and ERP capabilities may involve investment in software, equipment, systems or other business requirements. A business loan may be considered where additional funding is required for eligible business-related needs, subject to the lending firm’s assessment and applicable terms.
The applicable interest rate is determined based on factors such as the business profile, turnover, credit score, location, income and existing financial obligations. Businesses considering financing should first assess the purpose of the funding, their repayment capacity and the applicable eligibility criteria. The objective should be to use financing as part of a considered business plan rather than as a substitute for establishing an effective compliance process.
Conclusion: Strengthen systems to avoid reporting delays
The 30-day e-invoice reporting rule sets a clear deadline for GST compliance if your business has a gross revenue of ₹10 crore or more. Although e-invoicing applies to businesses with turnover above ₹5 crore, those in the ₹10 crore-and-above range should be especially careful about meeting the reporting deadline.
Businesses can prepare by reviewing their GST applicability, keeping invoice data accurate, maintaining compatible ERP systems and establishing clear internal responsibilities for invoice reporting. Where technology or other eligible business requirements call for additional funding, a business loan may be considered based on the business’s requirements, eligibility and repayment capacity.
