E-Invoice Limit in India: Updated Guide for Businesses

E invoice limit in India has become a crucial topic for all businesses, especially small and micro-sized enterprises trying to stay GST-compliant. With new rules and updates from the government, understanding the e-invoicing limit, its turnover threshold, and applicability is more important than ever.

In this guide, we’ll walk you through the latest e-invoice limit in GST, the current e-invoice applicability limit, how to generate e e-invoice, and how platforms like GimBooks can simplify the process for your business.

 E-Invoice Limit in India – 2026 Update

• Mandatory for businesses with annual turnover above ₹5 crore.
• Applicable to B2B invoices under GST.
• Helps prevent invoice fraud and ensures accurate tax compliance.
• Covers all types of invoices: goods, services, credit, and debit notes.

Current E-Invoice Limit in India for FY 2026–27

The current e-invoice limit in India is an aggregate annual turnover exceeding ₹5 crore. Under Notification No. 10/2023-Central Tax, effective from 1 August 2023, eligible GST-registered businesses must generate e-invoices if their aggregate turnover exceeded ₹5 crore in any preceding financial year from FY 2017–18 onwards.

The e-invoice limit in GST applies to eligible B2B transactions, exports and other notified supplies, subject to applicable exemptions.

The ₹5 crore threshold determines whether e-invoicing is mandatory, while the ₹10 crore threshold determines whether the separate 30-day IRP reporting restriction applies.

Businesses should not confuse these two requirements when checking their GST compliance obligations.

What is E-Invoicing?

Let’s start with the basics.

E-invoicing, or electronic invoicing, is a system where invoices are generated digitally and reported to the government through the GST portal. These invoices are validated and assigned an Invoice Reference Number (IRN) by the Invoice Registration Portal (IRP).

Once validated, the invoice is digitally signed and returned with a QR code. It ensures accuracy, reduces fraud, and streamlines tax filing.

E-Invoice Limit in GST: What’s the Turnover Threshold?

As per the latest notification by the GST Council, the e invoice limit has been reduced over time to cover more businesses. Here's how the applicability has evolved:

E-Invoice Turnover Limit History: GST Notifications and Effective Dates

The e-invoice turnover limit has been reduced in phases to bring more GST-registered businesses under the electronic invoicing system.

E-Invoice Limit Latest Notification

The e-invoice limit latest notification reducing the mandatory turnover threshold is Notification No. 10/2023-Central Tax, issued on 10 May 2023.

It reduced the earlier ₹10 crore threshold to ₹5 crore with effect from 1 August 2023.

The threshold remains applicable for FY 2026–27 under the current notified framework.

Businesses looking for the e-invoice limit 5 crore notification PDF can access the original notification through the official GST Council notification page.

The notification should be read together with the principal Notification No. 13/2020-Central Tax and its subsequent amendments to determine applicability and exemptions.

What Is the E‑Invoice Applicability Limit Now?

• Mandatory Applicability: All businesses with an Annual Aggregate Turnover (AATO) above ₹5 Crore in any financial year are currently required to generate e‑invoices under GST.
• Reporting Time Limit: From 1 April 2025, businesses with an AATO of ₹10 Crore and above must upload e‑invoices (including invoices, credit and debit notes) to the Invoice Registration Portal (IRP) within 30 days of the invoice date or the portal will reject them.

This 30‑day reporting rule was earlier applicable only to much larger taxpayers but has now been extended to the ₹10 Crore AATO category to improve timely compliance.

Why is E-Invoicing Important?

E-invoicing helps make business processes smoother and more transparent. Here’s why it matters:

Benefits of E-Invoicing

• Reduces human errors in invoices.
• Simplifies GST return filing with automated reporting.
• Improves cash flow by avoiding mismatches.
• Prevents fake invoices and reduces tax evasion.
• Enhances digital record-keeping for audits and compliance.

Is E-Invoicing Mandatory for Small Businesses?

If your annual turnover is below ₹5 crore, e-invoicing is not yet mandatory. However, it’s good to be prepared as the government may reduce the threshold further in the future.

Even if you are not required to generate e-invoices, using digital invoicing can help keep your records in order and avoid last-minute compliance problems.

E-Invoice Applicability for Manufacturers, Traders and Service Providers

The e-invoice mandatory limit is generally the same for manufacturers, wholesalers, retailers and service providers. There is no separate ₹10 crore mandatory e-invoicing threshold for manufacturing businesses.

The above requirements are subject to notified exemptions and the preceding-financial-year turnover test.

Which Transactions Require an E-Invoice Under GST?

For covered taxpayers, e-invoicing under GST generally applies to the following transactions:

• B2B taxable supplies to GST-registered recipients.
• Export invoices for goods or services.
• Eligible supplies to SEZ units and developers.
• Taxable supplies between different GSTINs under the same PAN.
• Eligible supplies to GST-registered government departments.
• Applicable GST credit notes and debit notes.

Ordinary B2C invoices, bills of supply for exempt supplies and purely commercial credit notes are generally outside the standard e-invoice mandate.

For example, a retailer with ₹8 crore aggregate turnover may need to generate e-invoices for eligible B2B sales while continuing to issue regular GST invoices for ordinary B2C sales.

The turnover threshold determines whether the supplier is covered, while the transaction type determines whether a particular document requires an IRN.

E-Invoice Time Limit: 30-Day Reporting Rule for ₹10 Crore Businesses

The e-invoice time limit depends on the applicable reporting requirement and the statutory time limit for issuing a tax invoice.

From 1 April 2025, taxpayers with aggregate annual turnover of ₹10 crore and above must report applicable invoices, credit notes and debit notes to the Invoice Registration Portal within the permitted 30-day window.

E-Invoice Generation Limit vs Reporting Time Limit

Example of the 30-Day E-Invoice Rule

A business covered by the 30-day restriction creates an invoice dated 1 November 2026.

The invoice must be reported to the IRP by 30 November 2026 under the applicable reporting-window calculation.

If it is reported after the permitted window, the IRP will reject the request for IRN generation.

Businesses below the ₹10 crore reporting threshold must still comply with the applicable invoice issuance and e-invoicing requirements if they are covered by the mandatory e-invoice rules.

The 30-day reporting window is not permission to issue an invalid invoice or delay IRN generation until month-end.

For practical deadline controls, read how to avoid missing the 30-day e-invoice reporting window.

If an incorrect IRN has already been generated, refer to the e-invoice cancellation process.

Who Is Exempt from E-Invoicing Under GST?

Even when the aggregate turnover exceeds ₹5 crore, certain notified categories of registered persons are exempt from mandatory e-invoicing.

The principal exemptions include:

• Special Economic Zone (SEZ) units.
• Insurers, banking companies and financial institutions, including NBFCs.
• Goods Transport Agencies covered by the specified exemption.
• Passenger transportation service providers covered by the relevant provision.
• Suppliers providing admission to cinematograph films in multiplex screens.
• Government departments and local authorities covered by the notification.

Are SEZ Developers Exempt from E-Invoicing?

The exemption for SEZ units should not automatically be extended to SEZ developers.

SEZ developers must check their own e-invoice applicability based on turnover and the applicable notification.

Similarly, an eligible supplier making taxable supplies to an SEZ unit may still need to generate an e-invoice for that transaction.

Is E-Invoicing Mandatory for Small Businesses?

A business that has never exceeded the prescribed ₹5 crore turnover threshold in any relevant preceding financial year is generally outside the mandatory e-invoicing requirement.

However, a business that exceeded the threshold in an earlier year may remain covered even if its current turnover is below ₹5 crore.

Businesses should verify their eligibility using historical PAN-based turnover rather than relying only on current annual sales.

Mistakes to Avoid in E-Invoicing

Avoid these common errors that can lead to penalties:

• Not generating the e-invoice before delivery.
• Missing required invoice fields.
• Using non-compliant software.
• Sharing invoices without IRN or QR code.

Stay ahead by using tools like GimBooks to reduce manual steps and prevent mistakes.
