E-Invoice Turnover Limit in India: Who Needs to Comply

As of 2026, the e-invoice turnover limit in India is ₹5 crore. If your aggregate annual turnover crossed ₹5 crore in any financial year from 2017-18 onwards, you must generate e-invoices for your B2B (business-to-business) supplies. This threshold has only ever moved downward, so confirm the current figure on einvoice.gst.gov.in before you decide you are exempt.

What is the e-invoice turnover limit right now?

The e-invoice turnover limit is the aggregate annual turnover at which a GST-registered business must start generating e-invoices. As of 2026, that limit is ₹5 crore.

"E-invoicing" does not mean emailing a PDF. It means uploading your invoice details to the government's Invoice Registration Portal (IRP), which validates the invoice and returns an Invoice Reference Number (IRN) plus a signed QR code.

The key word is aggregate. Your turnover is calculated across all GSTINs (your GST registration numbers) under the same PAN, all over India. So if you have one unit in Maharashtra and another in Gujarat under the same PAN, you add both together.

This figure changes. The government has lowered it several times and may lower it again. Always verify the current number on the official portal or with your CA before acting.

How "turnover" is counted

Aggregate turnover includes taxable supplies, exempt supplies, exports, and inter-state supplies. It is computed on an all-India PAN basis but excludes the GST itself. The trigger is any financial year since 2017-18, not just the latest one.

So even if your turnover dipped below ₹5 crore last year, once you have crossed the limit in any earlier year, you stay inside the e-invoicing net.

Exactly who and what it applies to

E-invoicing applies to most GST-registered businesses above the threshold, but the scope of transactions is narrower than people expect.

You must generate e-invoices for:

• B2B supplies: Taxable sales to other GST-registered businesses.
• Exports: Including supplies with or without payment of tax.
• Supplies to SEZ: Special Economic Zone units and developers.
• Deemed exports: As notified under GST law.
• Credit notes and debit notes: Issued against these B2B documents. See our guide on credit notes vs debit notes under GST for the difference.

You do NOT need e-invoices for:

• B2C supplies: Sales to unregistered end consumers. Read more on B2B vs B2C invoices under GST.
• Most exempt or nil-rated goods.

Businesses that are exempt regardless of turnover

Some categories are kept out of e-invoicing even when they cross the limit, as of 2026:

• Banks and financial institutions, including NBFCs and insurers.
• Goods Transport Agencies (GTA).
• Passenger transport services.
• Multiplex cinema operators (admission tickets).
• SEZ units (units, not developers).
• Government departments and local authorities.

These exemptions are set by notification and can change. Confirm your category on gst.gov.in or with your CA.

How the threshold has changed over time

E-invoicing started as a big-business rule and steadily reached down to small businesses. The direction has been one-way: downward.

• October 2020: Turnover above ₹500 crore.
• January 2021: Lowered to ₹100 crore.
• April 2021: Lowered to ₹50 crore.
• April 2022: Lowered to ₹20 crore.
• October 2022: Lowered to ₹10 crore.
• August 2023: Lowered to ₹5 crore (the limit as of 2026).

The pattern is clear. Each step roughly halved the threshold. If your turnover is approaching ₹5 crore, treat e-invoicing as something you will need soon, not later. If you run a smaller business, our guide on e-invoicing for businesses under ₹5 crore explains what to watch for.

Because the figure is volatile, do not rely on this list a year from now. Check the latest notification before you assume you are outside the net. For the full picture of how the system works end to end, see our complete GST e-invoicing guide.

Why the limit keeps dropping

E-invoicing tightens the GST chain. It curbs fake invoicing, auto-populates GSTR-1, and makes input tax credit (ITC) cleaner. The government wants more businesses inside the system, so the threshold keeps falling. For a deeper look at where the line sits, see our note on the e-invoice applicability limit.

What you must do once you cross it

Crossing the threshold is not optional paperwork. From the applicable date, an invoice without a valid IRN is not a valid tax invoice, and your customer may lose ITC on it.

1. Register on the e-invoice portal. Enable e-invoicing for your GSTIN on einvoice.gst.gov.in.
2. Set up invoicing software that can generate the required JSON and connect to the IRP, either directly or through a GSP (GST Suvidha Provider).
3. Generate the IRN for every B2B invoice before you issue it. See our step-by-step on how to generate an IRN.
4. Print the signed QR code and IRN on the invoice you hand to the customer.
5. Reconcile your e-invoice data with GSTR-1, since e-invoice details auto-flow into it.
6. Handle changes correctly. You cannot edit an IRN; you cancel within the allowed window and re-issue. Read e-invoice cancellation and amendment.

What happens if you ignore it

An invoice issued without an IRN, when you are required to have one, is treated as no invoice at all. That can mean penalties, denial of ITC to your buyer, and trouble during e-way bill generation, since the e-way bill system pulls from e-invoice data above the threshold.

Invodo handles the heavy lifting for you. It generates GST-compliant tax invoices, pushes them to the IRP, captures the IRN and QR code automatically, and keeps your data ready for GSTR-1. If you are at or near the ₹5 crore line, create your free Invodo account and stay compliant without rebuilding your billing process.
